Goats are amazing animals. They can survive just about anywhere. Altogether there are nine species of goats in the world. Goats have more uses than you could ever imagine. Goat's meat can be eaten and goat's milk is becoming popular as a healthy choice to drink milk. Goat's milk is easier to take in than cow's milk and it is called universal milk as it can be used to bottle-feed most animals. In nutrition, it is also good. Goat's skins are still used today to make gloves and other items of clothing. The initial reasons for domesticating goats were to get goat's hair, meat and milk. Goat's skins were used up until the Middle Ages for making bottles to hold water and wine for people who were traveling or camping. Just like sheep, goats are considered to be the first domesticated animal. The domestication process began over 10,000 years ago in a North Iranian town. A lot of people keep goats as pets nowadays. Goats are easily trained and you can teach them to pull carts and walk on ropes. Goats are also known for escaping their pens . If you have unsecured fencing, your goats will be interested in it and test it out and soon you will know where the openings are. Goats are also widely known for their ability to climb trees, although the tree generally has to be at a slight angle . If goats are raised correctly and trained from an early age, they never develop any bad habits. Goats will attack each other. However, if they're corrected from an early age they never attack humans or other animals. If you want to keep a goat as a pet, it is important _ .

American this year will swallow 15,000 tons of aspirin, one of the safest and most effective drugs invented by man. The most popular medicine in the world today, it is an effective pain reliever. Its bad effects are ly mild and it is cheap. For millions of people suffering from arthritis . It is the only thing that works. Aspirin, in short, is truly the 20th-century wonder drug. It is also the second largest suicide drug and is the leading cause of poisoning among children. It has side effects that, although ly mild, are largely unrecognized among users. Although aspirin was at first sold by a German company in1899, it has been around much longer than that. Hippocrates, in ancient Greek, understood the medical value of the leaves and tree bark which today are known to contain salicylates , the chemical in aspirin. During the 19thcentury, there was a great deal of experimentation in Europe with this chemical, and it led to the introduction of aspirin. By 1915, aspirin tablets were available in the United States. A small quantity of aspirin (two-grain tablets) relieves pain and inflammation. It also reduces fever by interfering with some of the body's reactions. The passage is written to _ .

I shall never forget the night, a few years ago, when Marion J. Douglas was a student in one of my calsses. (I have not used his real name for personal reasons. As he requested.) But here is his real story as he told it before one of our adult - education classes. He told us how tragedy had struck at his home, not once, but twice. The first time he had lost his five-old daughter, a child he adored. He and his wife thought they couldn't bear that first loss; but, as he said:"Ten months later, God gave us another little girl and she died in five days." This double was almost too much to bear. "I couldn't take it," this father told us. "I couldn't sleep, I couldn't eat, I couldn't rest or relax. My nerves were entirely shaken and my confidence gone." At last he went to doctors; one recommended sleeping pills and another recommended a trip. He tried both, but neither helped. He said:"My body felt as if it was surrounded in a vice , and the jaws of the vice were being drawn tighter and tighter." The tension of grief ----if you have ever been paralyzed by sorrow, you know what he meant. But thank God, I had one child left ----a four --year-- old son. He gave me the solution to my problem. One afternoon as I sat around feeling sorry for myself, he asked; 'Daddy, will you build a boat for me?' I was in no mood to build a boat; in fact, I was in no mood to do anything. But my son is a persistent little fellow! I had to give in. Building that toy boat took me about three hours. By the time it was finished, I realized that those three hours spent building that boat were first hours of mental relaxation and peace that I had had in months! I realized that it is difficult to worry while you are busy doing something that requires planning and thinking. In my case, building the boat had knocked worry out of the ring. So I determined to keep busy. The following night, I went from room to room in the house, making a list of jobs that ought to be done. Scores of items needed to be repaired: bookcase, stair steps, storm windows, window-shades, locks, leaky taps. Amazing as it seems, in the course of two weeks I had made a list of 242 items that needed attention. "During the last two years I have completed most of them. I am busy now that I have no time for worry." No time for worry! That is exactly what Winston Churchill said when he was working eighteen hours a day at the height of the war. When he was asked if he worried about his huge responsibilities, he said :"I am too busy. I have no time for worry." Marion felt his body as if it was caught in a vice because _ .

The Process of Ageing At the age of twelve years, the human body is at its most vigorous. It has yet to reach its full size and strength, and its owner his or her full intelligence; but at this age the possibility of death is least. Earlier, we were infants and young children, and consequently more vulnerable ; later, we shall undergo a progressive loss of our vigour and resistance which, though vague at first, will finally become so steep that we can live no longer, however well we look after ourselves, and however well society, and our doctors, look after us. This decline in vigour with the passing of time is called ageing. It is one of the most unpleasant discoveries which we all make that we must decline in this way, that if we escape wars, accidents and disease we shall eventually "die of old age", and that this happens at a rate which differs little from person to person, so that there are heavy odds in favor of our dying between the ages of sixty-five and eighty. Some of us will die sooner, a few will live longer -- on into a ninth or tenth decade. But the chances are against it, and there is a virtual limit on how long we can hope to remain alive, however lucky and physically strong we are. Normal people tend to forget this process unless and until they are reminded of it. We are so familiar with the fact that man ages, that people have for years assumed that the process of losing vigour with time, of becoming more likely to die the older we get, was something self-evident, like the cooling of a hot kettle or the wearing-out of a pair of shoes. They have also assumed that all animals, and probably other organisms such as trees, or even the universe itself, must in the nature of things "wear out". Most animals we commonly observe do in fact age as we do, if given the chance to live long enough; and mechanical systems like a wound watch, or the sun, do in fact ran out of energy in accordance with the second law of thermodynamics . But these are not similar or equivalent to what happens when man ages. A run-down watch is still a watch and can be rewound. An old watch, by contrast, becomes so worn and unreliable that it eventually is not worth mending. But a watch could never repair itself -- it does not consist of living parts, only of metal, which wears away by friction . We could, at one time, repair ourselves -- well enough, at least, to overcome all but the most instantly fatal illnesses and accidents. Between twelve and eighty years we gradually lose this power, an illness which at twelve would knock us over, at eighty can knock us out, and into our grave. If we could stay as vigorous as we are at twelve, it would take about 700 years for half of us to die, and another 700 for the survivors to be reduced by half again. What can be learned from this passage is that _ .

In the United States you will find yourself being urged from every page of every newspaper and every television station to buy all kinds of goods. Not only is there a wide range of prices for goods in America, there is also a wide range in the quality of goods offered for sale. Unlike some countries, Americans generally pay the price of a product without question, instead of trying to get a lower price by bargaining. However, there are many "sales" in the United States, during which time stores will lower their normal prices. This may all be very confusing to visitors. How are you going to know how to "get your money's worth" when you shop? Perhaps the best advice is: Don't hurry. Visit various stores and determine the quality of goods. Read the advertisements so that you can compare prices. There is a great variety of shops in the United States, ranging from very large stores called "department stores" to very small shops. There are "discount houses" offering goods at low prices, and "dime stores" specializing in a wide range of inexpensive items. Most department stores in large cities carry better quality products at higher prices. However, they offer the shoppers great convenience since they contain such a wide variety of products. If convenience isn't as important to you as price, you may want to shop in discount houses. These stores have nearly as great a variety of goods as department stores, but offer lower prices. They can do so for several reasons. They don't offer the same services to buyers that department stores do; there may be fewer sales people; and the store probably doesn't deliver purchases. Another popular shop is the "dime store". No longer selling many things for five or ten cents, these stores got their name in the last century when it was decided that a small profit on a great quantity of goods would be better than a large profit on fewer sales. Dime stores specialize in a wide variety of inexpensive items and today, prices range from a quarter or 50 cents up to several dollars. Where can we most probably read this passage?

We know that sugary sodas aren't good for our bodies. Now it turns out that they may not be good for our minds, either. A new study of more than 260,000 people has found a link between sweetened soft-drinks and depression, and diet sodas may be making matters worse. Americans drink far more sodas than people in other countries-- as much as 170 liters per person per year. But the impact of this study isn't limited to the United States. "Sweetened drinks, coffee and tea are commonly consumed worldwide and have important physical consequences. And they may have important mental-health consequences as well," study author Dr Honglei Chen said in a statement. The study studied 263,925 people between the ages of 50 and 71. Researchers followed their consumption of drinks like soda, tea coffee, and other soft drinks from 1995 to 1996 and then. 10 years later, asked them if they had been diagnosed with depression since the year 2000. More than 11,3000 of them had. Participants who drank more than four servings of sodas per day were 30 percent more likely to develop depression than participants who did not drink sodas at all. People who stuck with fruit punch , had a 38 percent higher risk than people who didn't drink sweetened drinks. And all that extra sugar isn't the actual problem. Researchers say that the artificial sweetener _ may be to blame. The study found a link but could not surely determine whether sodas and other sweet soft drinks cause depression. Still, the results "are consistent with a small but growing body of evidence suggesting that artificially sweetened beverages may be linked to poor health outcomes." But there's a bright side for those who can't live without their daily sodas. Adults who drank coffee had a 10 percent lower risk of depression compared to people who didn't drink any coffee, according to the study. "Our research suggests that cutting out or down on sweetened diet drinks or replacing them with unsweetened coffee may naturally help lower your depression risk," said Chen. It is implied in the passage that _ .

When I grew up, all the schools in the village demanded that girls cut their hair. The teachers would measure our hair and make sure it was not too long. I remember crying and begging as the scissors cut my hair. My dad told me that a girl who was in school needed to concentrate on books and that hair was a distraction . I cut my hair all the way through primary school and middle school. Then I went to a high school that allowed long hair but no styles or braids during class hours. Even then, still adhering to my dad's words, I never wore my hair long. When I graduated from high school, I started growing my hair. I spent hours looking in the mirror and shaping my hair. My sister complained, wondering why I had to have two styles in a day. In college I heard the word perm . Girls had some strong chemicals put on their heads and made the hair look beautiful. I quickly sat in a salon and changed my hair. I returned to the salon once every month. Even during the days when I had no money for food, I had to find money for my hair. After college, I was jobless and broke. I had to have my hair cut. At that time I saw a bald black model. Her style shocked me and I admired her so much that I began to follow her. Therefore, there I was. I wore some large earrings and walked around like a model. And many people admired my style. At this point the journey with my hair stopped completely. I decided to have natural hair. I soon found out natural hair is the cheapest, easiest and healthiest way to wear African hair. The author thought the bald black model looked _ .

Penguins can taste only sour and salty food, scientists have discovered. A genetic study suggests the flightless birds lost three of the five basic tastes long ago in evolution. Taste is critical for survival in most animals, but may not matter in the penguin, which swallows fish whole, say researchers in China and the US. Many other birds are unable to taste sweet things, but they do have receptors for detecting bitter and umami (or meaty) flavours. The discovery was made when researchers decoding penguin genomes found some of the taste genes were missing. A closer look at the DNA of penguins revealed that all species lack functioning genes for the receptors of sweet, umami, and bitter tastes. "Based on genetic data, penguins are believed to have sour and salty tastes, but have lost sweet, umami, and bitter tastes," lead researcher Prof Jianzhi Zhang, of the University of Michigan, US, and Wuhan University, China, told the reporter. The umami taste gives food the strong, savoury flavour associated with meat. Lacking this sense is surprising for a carnivorous animal, but does not matter that much in the penguin, which swallows fish without chewing. "Their behaviour of swallowing food whole, and their tongue structure and function, suggest that penguins need no taste perception," said Prof Zhang. "Although it is unclear whether these traits are a cause or a consequence of their major taste loss." The findings, published in Current Biology journal, were a puzzle, he added. One clue comes from the bird's evolution on the frozen ice sheets of Antarctica. Sending signals from sweet, umami, and bitter (but not sour or salty) taste receptors to the brain does not work at very low temperatures. This may have led to the penguin gradually losing its sense of taste, say the researchers. Intriguingly , the sweet taste is missing in almost all birds. The hummingbird, which feeds on sweet nectar, is an exception. Which of the following statements is not true according to the passage?

They don't quite know how to cope with all the dam trouble they've got down in Hampden, Maine. And according to town manager Leslie Stanley, it doesn't look as if things will improve any in the immediate future. "We've got a real annoying problem on our hands," he says. The annoyance began in late May. About three miles outside of town a group of beavers built a dam near the mouth of a culvert that carries a stream under Canaan Road. Some 50 feet of roadway and several hundred feet of land on each side of the culvert were flooded. Stanley sent a road crew out to level the dam. The beavers rebuilt it. The crew tore it apart again. In fact, they tore it apart for ten mornings-and for ten straight nights the beavers rebuilt it. On the eleventh day, the foreman tossed the problem back to the town manager. He, in turn, tossed it on to the local game warden . The warden, absorbed in beaver knowledge, moved quietly and carefully out one night and placed a petrol-soaked bag over the dam. (Any beaver expert will tell you the creatures just can't tolerate petrol smell.) In the morning the bag was found artistically woven into the dam. The warden set out three steel traps that night. In the morning one was empty. The other two had been stolen by the beavers and used to strengthen the dam. The warden, cursing the state law against hunting beavers with firearms, got his traps back and set them out again and again. And every night the beavers stole them. Town manager Stanley enlisted additional troops. He telephoned his police chief. Those beavers were breaking a state law against blocking up a natural watercourse. "Why aren't you out there to _ the law?" Stanley asked. "You're the police chief. So remove them. Arrest them. Do something." Three mornings later, the police chief proudly announced the end of the dam. At 2:00 A.M., he said, he and a licensed dynamiter had blown it to small pieces. Stanley said he'd believe it when he saw it. They drove out to the culvert and found a new dam already half-built. They also found the highway choked with mud and remains thrown up by the dynamite. Stanley said maybe they should call in the Army Corps of Engineers. But the police chief's faith in explosives was unshaken. He launched an all-out campaign,but the beavers always managed to have the holes plugged by the time the fire department appeared on the scene for its morning mop-up. In time, the beavers tired of this nonsense and moved their dam "inside" the culvert-where it couldn't be blown up without destroying the road too. Stanley and his general staff held a council of war and agreed that fresh strategy was called for. Then they came up with an inspired idea. If we remove every branch of the dam by hand, we'll force the beavers to go in search of new building material to replace what we've taken. Then we can place box traps along their runways and seized them. The plan was completely approved. Moreover it worked. On July 30, town manager Stanley was able to announce that the beaver group had been trapped and removed to a remote wilderness area. And there was great joy in Hampden-until the middle of October, that is, when a group of young beavers was spotted swimming in the same waters from which its elders had recently been taken away. But to make a long story short, the strategy that worked with the older beavers worked with the young ones too. What can we learn about beavers from the passage?

[
"The beavers seem to be stubborn about building dams.",
"The beavers are allowed to be killed when causing trouble.",
"The beavers can't adapt themselves to living in wilderness.",
"The beavers finally returned to the culvert with their young."

Our listener question this week comes from Abdullahi Farah, who wants to know about the life and work of Doctor Benjamin Carson. Doctor Carson is an internationally recognized doctor at Johns Hopkins Hospital in Baltimore, Maryland. He has been the director of Pediatric Neurosurgery at the hospital for twenty-five years. At the age of thirty-three, he became one of the youngest doctors in the United States to hold that position. And he was the first African-American to have that position at Johns Hopkins Hospital. Ben Carson is known for his work as a brain surgeon for children. For example, in nineteen eighty-seven, he led a team of seventy doctors and nurses in an operation to separate two babies joined at the head. Earlier attempts by other on other babies had failed. Doctor Carson successfully performed the operation. Both babies were able to survive independently. Doctor Carson has written four books. His first book, "Gifted Hands," tells the story of his life. Benjamin Carson was born in nineteen fifty-one in Detroit, Michigan. As a boy, Ben was not a good student. In fact, he was the worst in his class. When his mother learned of his failing grades she asked her sons to read two library books every week. She limited the amount of time they watched television. And she told them to respect every person. Ben Carson soon became the top student in his class. He went on to study at Yale University, one of the best universities in the country, and later to medical school at the University of Michigan. Doctor Carson has received many awards and honors. Last year he received the nation's highest civilian honor. Former President George W. Bush presented Benjamin Carson with the Presidential Medal of Freedom at a ceremony at the White House. The passage is probably taken from _ .

When you watch 3D movies or TV,you have to wear a special pair of glasses.The 3D glasses make the images from the screen look like they are there in the room with you. Three-dimensional,or 3D,means having three dimensions : width,height and depth.3D technology is based on the way the human brain and eyes work.Because the _ of a person's eyes are about 6.5era apart ,when we look at something,each eye sees it from a different angle .Our eyes send the two images to our brain,and the brain puts them together.The small difference between the image from the right eye and the image from the left eye allows us to see depth. When we view pictures and television in two dimensions,each eye gets the same information.That is because the image has no real depth,and there is only one of viewing it.So the goal of 3D technology is to get a different image into each of the viewer.It uses two film projectors.One projects a left eye image and the other projects a right image.The 3D glasses allow us to see a different image in each eye. While watching 3D films,we feel that we are in the same environment as the things we're watching.However,it also has its disadvantages.The 3D glasses work by controlling the amount of light that reaches the eyes.It makes the screen look darker.What's more,people with eye problems may get headaches if they spend too much time watching 3D movies,because their brains need to work harder to "read" the images. Which of the following is TRUE?

"3D glasses make the screen look brighter.",
"People with eye problems can't see 3D films.",
"A 3D film needs making by two film projectors.",
"3D glasses held people get the same image in each eye."

The Internet is becoming important in our life. How much do you know about it? The following questions and their answers will help you to know more about the Internet. What is the Internet? The Internet is a large, world-wide collection of computer networks . A network is a small group of computers put together. The Internet is many different kinds of networks from all over the world. These networks are called the Internet. If you have learned to use the Internet, you can have a lot of interest on the World Wide Web . What is the World Wide Web? The World Wide Web has been the most popular development of the Internet. It is like a big electronic book with millions of pages. These pages are called homepages. You can find information about almost anything in the world on these pages. For example, you can use the Internet instead of a library to find information for your homework. You can also find information about your favourite sport or film star, talk to your friends or even do some shopping on the pages. Most pages have words, pictures and even sound or music. What is e-mail? Electronic mail (e-mail) is a way of sending messages to other people. It's much quicker and cheaper than sending a letter. If you want to use e-mail, you must have an e-mail address. This address must have letters and dots and an @ (means "at"). For example: Lily @ Yahoo.com. Write a message, type a person's e-mail address, and then send the message across the Internet. People don't need to use stamps, envelopes or go to the post office because of the invention of the Internet. Quick, easy and interesting -- that's the Internet. The World Wide Web is like _ .

College provides an important platform for the future professional life.The grades speak well about the kind of student you are and will also determine the chances of further studies.You cannot do all things at one time.At time you need to decide what to do according to their importance.This is one good skill that you will be requiring even after graduation. There are few tips to help you at college: Just find the place where you will not be disturbed.Grab your reading material,note pad, pen and other necessities.Distraction is a biggest hurdle in focusing.You need to ask yourself what distracts you the most.Is it music from the neighbors,presence of someone at home, internet or anything else? Try to be aware of your weakest points and then stay away from them as much possible during your study time.The distraction may also include your friends and some other things.It is only you who can decide that what is best for you. When you are ready for studying,then arrange the reading material and decide what things you need to study first.Put maximum time on your weak and major subjects.Set aside your minor ones for few hours as you know that these are comparatively less important than the majors. Make a realistic study plan which you can follow and stick to it.There is no point of making all 8hr study schedule daily as you know that it's not possible for you.Start the preparation at least 4 weeks before the exams. While making a study plan,don't forget the breaks after every 90minutes of study.It will help your eyes to relax and focus in an effective manner.Make a checklist of small milestones and put this on your table so you can see them frequently.When you are done with one or more cross them from the list and focus on the new ones. By"Put maximum time on your weak and major subjcots.",the author suggests _ .

Has anyone noticed how, with the passage of time, one's relationship with one's grown-up daughters and sons becomes changed? I've been aware of this for some time but I'm not quite sure how to deal with it. Take the kitchen sink for example. Following a family get-together at my place, I walked into the kitchen to find Kate, my daughter carefully cleaning the sink. "Don't do that; what are you doing that for?" I said, unhappy about the hidden criticism. "Mum," she said, "you really ought to put your glasses on when you clean the sink. Behind the tap here was black!" But it's not just things like kitchen sinks. Another time Kate arrived to pick me up to lunch. She looked at me and then asked, "Mum, why do you use brown eyebrow pencil when your hair is grey?" A sudden memory of her, aged 14, going to her first mixed party flooded back. She had come in to say goodbye. For a moment I thought she'd been an accident. Both eyes were black. I remember suggesting that perhaps a little less eye make-up might be more effective. Now I told her, "My hair used to be brown." "It looks absurd." "Mrs. Menzies had dark eyebrows with grey hair." "Yes, but you're not Mrs. Menzies, are you?" she said triumphantly, as if that proved her point. But a recent event made me realize that something really must be done. She had returned some for a few weeks before getting married. One evening I went out on a dinner date. By the time my companion left me at the front door, it was about 2am. As I stepped in, an angry figure in a white nightgown stopped me. "Well, what time of night is this to be coming home?" she shouted. "Where have you been? I've been worried sick!" Shades of the past come back to disturb me. But what should I do about all this? Nothing, probably. Maybe, after all, it's only a stage young people are going through. The daughter thought her mother didn't clean the kitchen sink well because of her_.

New Scientist Event Instant Expert-- How Your Brain Works Saturday, 20 May 2017from 10:00 to 17:00 London, United Kingdom Ever wondered how your brain works? How that stuff in your head enables you to see, hear and think about the world around you, make decisions and act on them? Join six leading scientists to explore what we know about 4fcthe most difficult kilo of matter in the universe". The day will be chaired by psychologist and presenter of BBC Radio 4's All in the mirtd,Claudia Hammond. ' Overview: The brain has long been a source of fascination. In 1819, the radical thinker and surgeon William Lawrence put it like this: "It's strongly suspected that a Newton or Shakespeare excels other men only ... by having an extra inch of brain in the right place."

Rico is a dog who lives in Germany . His owners trained him from a young age to find his toys. When they say the name of a certain toy, Rico can find it. In fact, he seems to know the names of 200 toys! Some researchers in Germany wanted to test Rico. They put his toys in a room and then told him to go in the room and find a certain toy. Since nobody was in the room with Rico, he had no help from anyone finding the right toy. The researchers did this test forty times. Rico found the right toy thirty-seven times! Then the researchers tried something else. They put seven of Rico's toys in the room together with one new toy that Rico had never seen before. Then they told Rico to go into the room and get the new toy. This new toy had a name Rico had never heard before. Rico found the right toy seven out of ten times! Researchers cannot really say that Rico knows words or language. However, these tests seem to show that Rico can think about what he hears and think about what he knows. In fact, Rico seems to think and remember things as well as a three-year-old child. From these tests, animal researchers know one thing for sure. Rico has given them a lot to think about.

Parents in three Midwestern states will soon know just how good or bad their kids' driving is when their children take the car for a spin . Starting today, American Family Insurance is offering customers with teen drivers free cameras that record what happens when a sudden change in the car's movement occurs. The cameras record the action inside and in front of the car in 20-second audio-video clips . The clips are then transmitted to Drive Cam, a prefix = st1 /San Diegocompany that analyzes the clips for risky behavior. Among things the analysts look for is the response time of the drivers and if they are paying attention to the road. Parents can receive a report on their kids' driving and view the clips on a home computer. Car accidents are the leading cause of death among U. S.teens, according to the NHTSA(National Highway Traffic Safety Administration). "There will be fewer accidents," Rick Fetherston, vice president at American Family said of the new system. American Family will test the system out by offering it for free for one year to 30.000 families in Wisconsin, Indiana and Minnesotato see whether the system results in fewer accidents. If the system is proven to prevent accidents, customers who volunteer to use it might see their insurance premiums drop. The company would not be viewing the videos or individual score cars, unless there is an accident. Bruce Moeller, president of Drive Cam, says his company's system is already being used by companies with lots of cars. "Some of our customers are reporting a 30% to 90% reduction in their risky driver events," Moeller says. But a lawyer in Minneapolissays. "If I felt I needed a camera in the car to watch over my kids, I shouldn't be letting them drive." American Family tested the system in two high schools in Minnesota and Wisconsin. Megan Ireland, 17, said the camera caught her stopping too late and taking turns too fast. The student at Prior Lake High School in Savage, Minn., said she didn't like it because she felt it invaded her privacy but has warmed up to the system. "Now I don't really have a problem with it because it's made me a better driver," she says. "For real." The camera is being offered to _ by _ free of charge now.

The olinguito is new to science. Although lt has been living in the cloud forests of South Amcrica for some time. Scientists say the olinguito is the first new carnivore discovered In the Americas in more than 30 years. It is a hairy orange-brown creature with a sweet face and big eyes The animal has small. rounded ears and lives in the trees An adult weighs one kilogram and measures about 75 centimeters. with half of those centimeters taken up by its ringed tail Most of the time. it likes to eat fruit, although it also eats meat. Active at night, the animal has lived in Colombia and Ecuador for a long time. But the olinguito did not exist in science books before now. Kristofer Helgen, director at the National Museum in Washington, led the research team that confirmed the existence of the olinguito. It had been mistaken more than a century ago for a look-alike animal -- a similar but larger olingo . Mr. Helgen had been studying olingos in a museum for ten years. At that time. he observed a difference in the size and shape of the heads and teeth. That led him on an effort to prove he was looking at an animal never before described by science. He got lucky when he communicated with a zoologist in Ecuador. The animal expert there made a short video that shows an olinguito in the trees. The video confirms that the oiinguito is different from the olingo Mr. Helgen says tens of thousands of olinguitos live in the wild and are not in danger of disappearing forever. Human beings, however, are moving closer to the olinguito habitat in the Andean cloud forests. The research team estimates that 42 percent of historic olinguiio habitat has been removed We can infer from the text that _ .

Many people think the camel stores only water in its hump ,but it does not,Instead,the camel stores something else there----food.The camel's hump is really a hump of fat.When the camel,often called"a ship of the desert",is not travelling and is in a place where there is plenty of food and water,it eats and drinks a lot. As it does so, its hump rises from the fat its body makes. Then when the camel is travelling through the desert and when there is little food,it can live off the stored fat. A camel can go on for days or weeks with little feed or water.However its hunger reaches the point starvation ,its hump shrinks and may even slip off its back and hang down its side. Camels are not fussy about what they eat.Thorny plants don't hurt their mouths,grasses of any kinds will do and so will hay,dry grain,cactuses.(,,) There are one--humpcamels and two--hump camels.

Everywhere man is altering the balance of nature.He is facilitating the spread of plants and animals into new regions, sometimes deliberately, sometimes unconsciously.He is covering huge areas with new kinds of plants, or with houses, factories, slag-heaps and other products of his civilization.He exterminates some species on a large scale, but favours the multiplication of others.In brief, he has done more in five thousand years to alter the biological aspect of the planet than has nature in five million. Many of these changes which he has brought about have had unforeseen consequences.Who would have thought that the throwing away of a piece of Canadian waterweed would have caused half the waterways of Britain to be blocked for a decade, or that the provision of pot cacti for lonely settlers' wives would have led to Eastern Australian being overrun with forests of Prickly Pear? Who would have prophesied that the cutting down of forests on the Adriatic coasts, or in parts of Central Africa, could have reduced the land to a semidesert, with the very soil washed away from the bare rock? Who would have thought that improved communications would have changed history by the spreading of disease-sleeping sickness into East Africa, measles into Oceania, very possibly malaria into ancient Greece? These are spectacular examples; but examples on a smaller scale are everywhere to be found.We make a nature sanctuary for rare birds, prescribing absolute security for all species; and we may find that some common and hardy kind of bird multiplies beyond measure and ousts the rare kinds in which we were particularly interested.We see, owing to some little change brought about by civilization, the starling spread over the English country-side in hordes.We improve the yielding capacities of our cattle; and find that now they exhaust the pastures which sufficed for less exigent stock.

Linus Pauling,the only person who has won two undivided Nobel Prizes,was born in Portland,Oregon. He attended Washington High School but because of an unimportant detail he did not receive his diploma until 1962,long after he had received his Bachelor's degree in chemical engineering from Orgon State College in 1922. He had chosen to study his major because he could get a good job with it. He won the Nobel Prize for Chemistry in 1954 for his research into the nature of the chemical bond and its application to the explanation of the structure of complex substance. His interest in the "behavior" of molecules led him from physical chemistry to biological chemistry,especially of the human body. He began with proteins and their main parts,the amino acids ,which are called the"building blocks of life".In 1950,he constructed the first satisfactory model of a protein molecule,a discovery very important to the understanding of the living cell. During World WarII,Pauling was a member of the Research Board for National Security,for which he was awarded the Presidential Medal of Merit in 1948. However,the use of the atomic bomb near the end of the war turned Pauling in a new direction. Having long worked on the structure of molecules,he took an immediate interest in the deadly effects of nuclear fallout on human molecular structures. From then on,Pauling protested the production of the hydrogen bomb and supported the prevention of the spread of nuclear weapons. Through his efforts,The NuclearTestBan Treaty,declaring all nuclear tests to be illegal except underground ones,came into effect on October 10,1963,the same day Linus Pauling was awarded the Nobel Peace.

Second Life is a 3D online world in which computer users can create a new life and live a different life. Second Life is one of the most popular new online games. But unlike other games, Second Life is not about winning or losing. Second Life is technically a computer game. But people involved in it do not consider it a game because the players create everything. Second Life is more for socializing and creating communities. Users of Second Life are called residents( ). To take part, they must create an avatar, or an electronic image of themselves. Some avatars look like humans, while others look like animals or imaginary creatures. Inside the Second Life world, residents live in different versions of themselves. They build homes, run businesses, buy and sell things, work, play, and attend schools. They even have relationships and get married. Second Life was created in 2003 by Linden Lab in San Francisco, California. Linden Lab controls the website where the ever-changing world is being created. There are now about one million people around the world who are active to Second Life. The number has grown quickly since the beginning of the year when there were about one hundred thousand users. The average age of people involved with Second Life is about thirty. However, Linden Lab has recently created Teen Second Life for young users. Second Life has its own economy and its own money, called Linden dollars. Millions of dollars are made and spent each month in Second Life. Users can enter Second Life for free. But they must pay for a membership if they want to own land or buy and sell goods and services. Recently, several major companies have become involved with Second Life. They want to be part of the growing business world that exists within the made-up reality. Which of the following statements is NOT true about Linden Lab?

This March, the H7N9 virus hit Zhejiang, Shanghai, Anhui, Jiangsu and so on. It seemed that most people who were infected with H7N9 had the common flu. Some people suffered from a fever or a cough. Don't be afraid---it's not easy to be infected with the virus. Here is some advice to help you protect yourself when it comes. Wash your hands. You need to wash your hands with soap and hot water before you eat, after you use the toilet , and after you touch animals, because your hands may carry viruses. Cover your nose and mouth, when someone sneezes or coughs, flu viruses can travel as far as one meter through the air, so you'd better stand a proper distance while talking to someone who has a cold. And always cover your nose and mouth with a piece of paper when you sneeze or cough, and then clean your hands. Wear a mask . Some doctors say that masks can stop the flu as much as 80%, but if you don't wash your hands often, it's no use wearing a mask. And it's necessary to wear a mask in the groups of people. Do sports often. Exercise will help your body strong enough to _ the virus. How many ways to stop the virus are mentioned in the passage?

Rainy days don't have to get you down, a happiness expert has claimed. Paul Dolan, Professor of Behavioral Science at the London School of Economics, said that people only feel _ in bad weather because they think about it too much. Studies have shown that people who live in warm, sunny climates are no happier than those in chilly, wet climates, he says. So the British talking about the weather may be making us gloomier than the weather itself. He said: "A study was done that measured the happiness levels of people in California compared to the North West. "They expected that people in California would be happier because it is more sunny, but they found that levels of happiness were exactly the same. "If it is sunny every day you get used to it and the sunshine doesn't make you any happier. "Most of the time the weather doesn't affect our well-being at all. But when we think about it, and think that it does, that's when we get miserable." In his new book, Happiness By Design, Dolan argues that we can think ourselves happy by taking our attention away from what makes us sad. "Most of our anxieties come from what might be," he argues. "If you want to be happier, pay attention to the things that make you feel good." He also claimed that a problem shared was not always a problem halved. He claimed that humans are actually very good at being able to get over tragedy and loss. Professor Dolan also admitted for the first time that he had a stammer , which had made his early life miserable. He claimed it only got better when he learned not to pay attention to his speech problem. "Things are never as bad as you imagine them being," he said. People in California _ compared to people in the North West.

Large companies need a way to reach the savings of the public at large. The same problem, on a smaller scale , faces practically every company trying to develop new products and create new jobs. There can be little hope of raising the money needed from friends and people we know, and while banks may agree to provide short-term finance , they are generally unwilling to provide money, for long-term projects. So companies turn to the public, inviting people to lend them money, or take a share in the business in exchange for a share in future interests. This they do by issuing stocks and shares in the business through the Stock Exchange. By doing so they can put into circulation the savings of single persons and institutions, both at home and abroad. When the saver needs his money back, he does not have to go to the company with whom he originally placed it. Instead he sells his shares through a stockbroker to some other saver who is seeking to _ his money. Many of the services needed both by industry and by each of us are provided by the government or by local organizations. Without hospitals, roads, electricity, telephones and railways, this country could not work. All these require continuous spending on new equipment and new development if they are to serve us properly, requiring more money than it is raised through taxes alone. The government, local organizations and nationalized industries therefore frequently need to borrow money to finance(...) major capital spending, and they, too, come to the Stock Exchange. There is hardly a man or woman in this country whose standard of living does not depend on the ability of his or her employers to raise money to finance new development. In one way or another his new money must come from the savings of the country. The Stock Exchange exists to provide a channel through which these savings can reach those who need finance. The money which enables these companies to go ahead with their projects is _ .

Motherhood may make women smarter and may help prevent dementia in old age by bathing the brain in protective hormones , U.S.researchers reported on Thursday. Tests on rats show that those who raise two or more litters of pups do considerably better in tests of memory and skills than rats who have no babies, and their brains show changes that suggest they may be protected against diseases such as Alzheimer's .University of Richmond psychology professor Craig Kinsley believes his findings will translate into humans."Our research shows that the hormones of pregnancy are protecting the brain, including estrogen , which we know has many neuroprotective effects," Kinsley said. "It's rat data but humans are mammals just like these animals are mammals," he added in a telephone interview."They go through pregnancy and hormonal changes." Kinsley said he hoped public health officials and researchers will look to see if having had children protects a woman from Alzheimer's and other forms of age-related brain decline. "When people think about pregnancy, they think about what happens to babies and the mother from the neck down," said Kinsley, who presented his findings to the annual meeting of the Society of Neuroscience in Orlando, Florida. "They do not realize that hormones are washing on the brain.If you look at female animals that have never gone through pregnancy, they act differently toward young.But if she goes through pregnancy, she will sacrifice her life for her infant--that is a great change in her behavior that showed in genetic alterations to the brain."

Boom boom!( I'm here, come to me!) Krak krak!( Watch out, aleopard !) Hok hok hok!( Hey, crowned eagle!) Very good -- you've already mastered half the basic vocabulary of the Campbell's monkey, which lives in the forests of the Tai National Park in Ivory Coast. The adult males have six types of call, each with a specific meaning, but they can mix two or more calls together into a message with a different meaning. Having spent months recording the monkeys' calls in response to both natural and artificialstimuli , a group led by Klaus Zuberbuhler of the University of St. Andrews in Scotland argues that the Campbell's monkeys have a certain form ofsyntax . This is likely to be controversial because despite great effort to teachchimpanzees language, they showed little or no ability to combine the sounds they learned into a sentence with a larger meaning. Syntax, basic to the structure of language, uniquely belongs to humans. "Krak" is a call that warns of leopards in the neighborhood. The monkeys give it in response to real leopards and to leopard shouting broadcast by the researchers. The monkeys can vary the call by adding "-oo": "Krak-oo" seems to be a general word for hunter, but one given in a special context - when monkeys hear but don't see a hunter, or when they hear the alarm calls of another species. The "boom-boom" call invites other monkeys to come toward the male making the sound. Two booms can be combined with a series of "krak-oos", with a meaning entirely different to that of either of its single parts. "Boom boom krak-oo krak-oo krak-oo" is the monkey's version of "Timber!" - it warns of falling trees. If Zuberbuhler is correct, the Campbell's monkeys can both vary the meaning of specific calls by adding something and combine calls to make a different meaning. What is the passage mainly about?

Scottish pupils recently were part of a new scheme that allowed them to take their exams online. Those examinations provided a glimpse of the future in May when 120 _ in 10 centers in Scotland sat in front of computers to take a multiple-choice online exam. Although candidates were using a computer mouse instead of a pen, in all other ways the exam was the same as normal. Exam rooms were set out to ensure that only the candidates and the teachers were able to see the individual screens. The online answers were sent directly to a safe area. According to the students at St Ninian's in East Renfrewshire who took an online French exam, it was definitely the most motivated they had ever felt when taking an exam. "I could go as fast as I wanted to, rather than as slow as everyone else wanted to," said one. "It was better than looking back and forth between the questions," said another. One pupil even described it as fun. Their head teacher, Dorothy Graham, was not so surprised, "They are so used to doing things on computers that it seems natural for them. The boys liked it because they didn't have to worry about how neat their work was." The only things that worried her were power cuts and systems' crashing. It's thought that online exams could be the norm in about five years. However, last year there were warnings about computerizing exams in England and Wales. It's thought that it could be unfair to some students if they come from homes without access to a computer. We can learn from the passage that it is mainly about _ .

Where is Love? How can we find Love? Once a little boy wanted to meet Love. He knew it was a long trip to where Love lived, so he got his things ready with some pizzas and drinks and started off. When he passed three streets, he saw an old woman sitting in the park and watching some birds. She looked very hungry. The boy gave her a pizza. She took it and smiled at him. The smile was so beautiful that he wanted to see it again, so he gave her a Coke. She smiled once again. The boy was very happy. They sat there all the afternoon, eating and smiling, but they said nothing. When it grew dark, the boy decided to leave. But before he had gone more than a few steps, he turned around, ran back to the old woman and gave her a hug. The woman gave him her biggest smile ever. When the boy opened the door of his house, his mother was surprised by the look of joy on his face and asked what had made him so happy. "I had lunch with Love. She has got the most beautiful smile in the world." At the same time, the old woman,s son was also surprised at his mother,s pleasure and asked why. "I ate a pizza in the park with Love," she said, "and he is much younger than I expected." If the world is full of love, we can enjoy a better life. When the little boy saw the old woman, she was _ .

Growing up in Puerto Rico, our family was no different from so many others. My parents got married after my father came back when the war ended. Both of my parents were struggling with the hard economic realities of the time. But somehow, they found time to cherish those cultural values that shaped our everyday life. In our daily life, we celebrated together with our friends or family members every birthday, every graduation, and all holidays with music and dancing, typical foods. When we visited our family in the countryside -- a trip that took about two hours in a car, with five children fighting as to who would get a window or the front seat -- we would break into song, and somehow the trip would turn into one full of happiness and fun. We would sing not only interesting children's songs but also beautiful love songs -- songs about the love of the country though we didn't understand the meaning of the words many times. I came to Philadelphia for the first time in 1973 to do a residency in family medicine. I remember the many hours of work. I was facing issues of life and death and suffering the clearly social unfairness and issues of poverty and race. These were all aggravated by my feeling of cultural differences. An important turning point in my life happened one Saturday night when I attended a concert of Puerto Rican singer and composer Antonio Caban Vale. The music showed my familiar rhythms, and the words spoke to my heart. I had found a space to express, celebrate, and share my culture in Philadelphia. Therefore, I believe diversity is seen as an advantage and not as a disadvantage. As a Puerto Rican, I am a mixture of races and I believe in my strength because of this. What do we know about the author's parents?

People who smoke could lose around one third of their daily memory, researchers say. A study by a team at Northumbria University showed that smokers lost more of their memory when compared to non-smokers. And the research also found that those who kicked the habit saw their ability to recollect information restored to almost the same level as non-smokers. The study involved more than seventy 18-to-25-year-olds and included a tour of the university's campus. Those who took part were asked to recall small details, such as a list of songs played at a campus concert and tasks completed at various points-known as real world memory test. Smokers performed badly, remembering just 59 percent of tasks. But those who had given up smoking remembered 74 percent and those who had never smoked recalled 81 percent of tasks. Dr. Tom Heffernan, who leads Northumbria University's Collaboration for Drug and Alcohol Research Group, said the findings would be useful in anti-smoking campaigns. He said, "Given that there are up to 10 million smokers in the UK and as many as 45 million in the United States, it's important to understand the effects smoking has on everyday cognitive function-of which prospective memory is an excellent example. " "This is the first time that a study has set out to examine whether giving up smoking has an _ on memory. We already know that giving up smoking has huge health benefits for the body, but this study also shows how stopping smoking can have knock-on benefits for cognitive functions too. '' The research will now investigate the effects of passive smoking on memory, while Dr. Heffernan and Dr. Terence O'Neil will look into the effects of third-hand smoking-toxins left on curtains and furniture. What will Dr. Heffernan and Dr Terence O'Neil do?

James Proud, a British businessman who settled in San Francisco launched a Twitter campaign called "Stop DST". Daylight Saving Time (DST) refers to the time during the summer when clocks are one hour ahead of standard time. "Daylight saving was created to save energy, and it doesn't really do that." Proud said, "but what's even worse are its negative health effects. It's both outdated and harmful." daylight saving has been linked to a surprising number of health issues such as heart attacks, but Proud has a particular interest in the topic because of its disruptive effects on sleep. Last year, German researchers suggested that our body cocks never really adjust t daylight saving, which causes a host of health problems. Till Roenneberg of Ludwig-Maximillians University said that because of DST, "the majority of the population has severely decreased productivity, decreased quality of life, increasing chance of getting illness, and is just plain tired." The week after daylight saving also witnesses a sudden increase in fatal traffic accidents, according to the University of Colorado. It is believed that this is caused both by disrupted sleep schedules and the shift of daylight hours from the morning to the evening. "Daylight saving is an economic tradition. And all economic choices involve achieving a balance. " said behavioral economist David Gerard. "Even if we decide to abolish daylight saving, there would be a large number of unhappy people." Some such people are shift works, students and parents of schoolchildren, all of whom get to enjoy an extra hour of daylight after work or class with DST. Plus, restaurants love the extra evening sales DST allows. Daylight saving has also been linked to lower crime rates, due to the "deterrent effect" of longer daylight. Basically, more light increase a criminal's chances of being seen by witnesses or police, which discourages criminal activity. Gerard also point out that an extra hour of daylight has vastly more influence in the American South, where the sun sets earlier, even in the summer, than in the north. That's why residents of southern states may values DST more. What causes Proud's greatest concern?

We have met the enemy, and he is ours. We bought him at a pet shop. When monkey-pox, a disease usually found in the African rain forest, suddenly turns up in children in the American Midwest, it's hard not to wonder if the disease that comes from foreign animals is homing in on human beings. "Most of the infections we think of as human infections started in other animals, " says Stephen Morse, director of the Center for Public Health Preparedness at Columbia University. It's not just that we're going to where the animals are, we're also bringing them closer to us. Popular foreign pets have brought a whole new disease to this country. A strange illness killed Isaksen's pets, and she now thinks that keeping foreign pets is a bad idea. "I don't think it's fair to have them as pets when we have such a limited knowledge of them," says Isaksen. "Laws allowing these animals to be brought in from deep forest areas without stricter control need changing," says Peter Schantz. Monkey-pox may be Researchers believe infected animals may infect their owners. We know very little about these new diseases. A new bug may be kind at first. But some strains may become harmful. Monkey-pox doesn't look a major infectious disease. But it is not impossible to pass the disease from person to person. What does the phrase "the wake-up call " in Paragraph 3 most probably mean?

Scientists have always been interested in the high level of organization in ant societies. American researchers have watched ants build life-saving rafts to keep afloat during floods. They also have documented how ant colonies choose their next queen--the female whose job is to produce eggs rather than seek food for others. New technology is helping to improve researchers' understanding of the insects. But there is still a lot to be learned. Fire ants living in Brazilian forests are perfectly at home in an environment where flooding is common. To save themselves, the insects connect their legs together and create floating rafts. Some ant rafts can be up to 20 centimeters wide. David Hu who is a mechanical engineer with the Georgia Institute of Technology, also known as Georgia Tech, says, "If you have 100 ants, which means 600 legs, 99 percent of those legs will be connected to a neighbor. So they're very, very good at maintaining this network." David Hu and other Georgia Tech researchers want to study ants and the secret of their engineering. They freeze ant rafts and then look at them with the help of computed technology, or CT, images. The pictures show that larger ants serve in central positions to which smaller ants hold. The larger ants form pockets of air that keep the insects afloat. Scientists say small robots or materials that can change shape could be programmed in a similar way, working towards a shared goal. Researchers at North Carolina State University are also studying ants. They examined how Indian jumping ants choose the leader of the colony when they lose their top female or queen. What can we know from what David Hu said?

Today, as in every other day of the year, more than 3,000 U.S. adolescents will smoke their first cigarette on their way to becoming regular smokers as adults. During their lifetime, it can be expected that of these 3,000 about 23 will be murdered, 30 will die in traffic accidents, and nearly 750 will be killed by a smoking-related disease. The number of deaths due to cigarette smoking outweighs all other factors, whether voluntary or involuntary, as a cause of death. Since the late 1970s, when daily smoking among high school seniors reached 30 percent, smoking rates among youth have declined. While the decline is impressive, several important issues must be raised. First, in the past several years, smoking rates among youth have declined very little. Second, in the late 1970s, smoking among male high school seniors beat that among female by nearly 10 percent . The statistic is reversing . Third, several recent studies have indicate high school _ have excessively high smoking rates, as much as 75 percent . Finally, though significant declines in adolescent smoking have occurred in the past decade, no definite reasons for the decline exist. Within this context, the National Cancer Institute (NCI) began its current effort to determine the most effective measures to reduce smoking level among youth. Every day there are over _ high school students who will become regular smoker.

"Hey, don't read in the hallway. Your eyesight will be damaged." You must have heard such warnings many times. Don't read in dim light! This is one of the "pearls of wisdom" that are supposed to help us live a healthy life. Such common beliefs, however, lack scientific basis, according to a paper published recently in theBritish Medical Journal. Do you believe in the following everyday wisdom? Reading in dim light ruins your eyesight. In dim light, you might blink more, feel discomfort from drying and have trouble focusing. But the majority of eye experts believe it is unlikely to do any permanent damage. We must drink at least eight glasses of water a day In 1945, the Nutrition Council in US suggested that people need to consume 2.5 litres of water a day. But the water contained in food, particularly fruit and vegetables, as well as in milk, juice and soft drinks, also counts towards the total. We only use 10 percent of our brains. This myth arose as early as 1907. People have long argued about our power of self-improvement and our brains' potential abilities. But detailed imaging shows that no area of the brain is silent or inactive. Shaving your legs causes hair to grow black faster and thicker. This theory is also illusion. Shaving has no effect on the thickness or rate of hair growth, studies say. Just over time, the edge of hair gets worn away and thus the edge of long hair becomes finer . So hair that is newly grown gives the impression of darkness. What does the paper say about some common beliefs?

About ten men in every hundred suffer from color blindness in some way. Women are luckier, only about one in two hundred is affected in this matter. Perhaps, after all, it is safer to be driven by a woman! There are different forms of color blindness. In some cases a man can not see deep red. He may think that red, orange and yellow are all shades of green. Sometimes a person cannot tell the difference between blue and green. In rare cases an unlucky man may see everything in shades of green - a strange world indeed. Color blindness in human beings is a strange thing to explain. In a single eye there are millions of very small things called "cones". These help us to see in a bright light and to tell difference between colors. There are also millions of "rods" but these are used for seeing when it is nearly dark. They show us shape but no color. Some insects have favorite colors. Mosquitoes like blue but do not like yellow. A red light will not attract insects, but a blue lamp will. In a similar way human beings also have favorite colors. Yet we are lucky. With the aid of the cones in our eyes we can see many beautiful colors by day, and with the aid of the rods we can see shapes at night. One day we may even learn more about the invisible colors around. We can attract and kill mosquitoes by using a _ .

Have you ever heard of blogs ? If you haven't, you should have. It's here, it's growing and it's having an influence on our life. Surf the Internet and you'll find blogs everywhere. A blog, shortened from "weblog", is a public Internet journal written by one person or a group of people. It is a website in which a person or a group can place news, personal thoughts, text, photos, video or audio files, or links upon which visitors can comment. A blog lets you post on the Internet without having to know web design or be technical. You are given an environment to make dated entries on the topic of your choice which are "published", so other people can read them. Authoring a blog, maintaining a blog or adding an article to an existing blog is called "blogging". Blogging has revolutionized Internet publishing in the last several years because it gives everyone with Internet access the opportunity to become an online writer. Objects, such as "text and photos" in a blog can be called "blog posts", "posts", or "entries". The person who posts these entries is called a "blogger". Now, somewhere around the world, a blog is created almost every 6 seconds. Because it's great potential, Bill Gates views it as important as e-mail, BBS, and MSN. He's trying to make blogs the important tools for future business communications. A blog is _ .

Is your TV connected to the Internet? What about your chair,or your fridge? Probably they are not. But in the future, most things in your home may be connected, thanks to the so-called "Internet of things". The Internet of things may be coming sooner than you think. Earlier this year, A Samsung CEO spent a lot of time talking about the Internet things. He said that five years from now,every Samsung product will be part of the Internet of things,no matter whether it's a remote control or a washing machine. So, how do household objects that are part of the Internet of things work? Well,think of a common chair. When connected to the Internet, the chair warms up when it knows the user has just walked into the room and is feeling cold. An Internet-connected camera could help people feel safer in their homes. It can know people's faces and has an infrared sensor ,so even if it's dark it can see when someone passes by and send you a message on your smartphone to let you know who's there. If the person is someone you don't know,it can tell you that ,too. But according to MIT Technology Roview, whether companies are connecting dog food bowls or security systems to the Internet, there may be some problems. For example, many early connected-home objects don't have much built-in security, which means they could be hacked . Morever, it could be difficult to get these new machines to work together especially when they are made by different companies. To fight this ,many companies have joined the Open Interconnect Consortium, which had 45 menbers by late 2014. So, picture this: you enter your home.The temperature changes to make you feel comfortable. Your favorite music starts playing for you. Do you think that this would be a good thing? I t may happen sooner than you think. What does the article mainly talk about?

Deep in the western Amazon rainforest, live butterflies that drink turtle tears. That sounds like a line straight out of a fantasy novel, but it's one hundred percent real life! It's an unusual sight--a crowd of butterflies flying around the eyes of yellow-spotted river turtles, trying to get a little tear.s. The poor turtles try to avoid them, hut the butterflies insist drinking their tears until they've had their fill. The butterflies are likely attracted to the turtles' tears because the liquid drops contain salt, specifically sodium, an important mineral that is rare in the western Amazon rainforest, said Phil Torres, a scientist who does much of his research at the Tambopata Research Center in Peru and is associated with Rice Univtrsity. Turtles get plenty of sodium through their largely carnivorous diet. Meat contains significant levels of the salt, Torres told LiveScience. But herbivores butterflies sometimes .struggle to get this extra mineral source, he added. Torres explained the western Amazon rainforest is lower in sodium than many places on earth, because it t is over l,000 miles away from the Atlantic Ocean---a main source of salt. The region is also cut off from the mineral dirt blown towards the west from the Andes Mountains. Most of these windblown minerals are removed from the air by the rain before they have a chance to reach the western Amazon. In fact, the butterflies have other sources to get sodium besides turtles' tears, which include animal urine , muddy river banks, sweaty clothes and so on. People can't help wondering if the process is painful for turtles. Torres said it's not completely clear, but the teary effort probably has little effect on the turtles, other than perhaps making them more vulnerable to their enemies like big cats, since the butterflies can block out their vision. The butterflies drink turtle tears to _

The events of Saturday night in Kunming are deeply engraved in the mind of Xie Qiming, who narrowly escaped death in the terrorist attack at the city's railway station. The 48-year-old policeman intervened to stop the butchering of unarmed civilians, saving many from death and injury, but he was injured in the process. Lying in a hospital bed, his head and nose marked by serious hacking wounds - one more than 20 centimeters long - Xie recounted his actions on the day he describes as a nightmare. "I shot at them but fell to the ground during the fighting. After the shots, the terrorists turned their attention to the police and several of them surrounded me and stabbed me like crazy," he said. "There is no humanity in them." Xie is from the Beijinglu Police Station, the closest to the attack, and four police officers from the station were the first to respond. He survived because he was wearing a bulletproof vest, which was damaged by the attackers. When the officers arrived, the attackers were running out of the ticket hall, attacking people with long knives. Xie and his colleagues tried to stop the attack, which is when Xie was injured. In addition to the deep cuts, his skull was fractured, and at the time of writing he was awaiting further surgery. "A wave of fierce anger rose up in my mind, and we all forgot to think about the possible danger to us," said Hu Zhe, 23, a police officer trainee at the Beijinglu Police Station. Having no firearm, he fought the terrorists with a wooden baton, but it got broken in the fighting. He sustained a 6-centimeter wound to his left eyebrow. Wan Weiqing, a neurosurgeon from Beijing Tiantan Hospital, learned of the attack at 2 am on Sunday and took the first flight to Kunming, where he has been helping the victims. He said that 71 victims are being treated at the Kunming First People's Hospital, most of them with severe multiple injuries. "There is one victim whose rib, breastbone, lung and even heart were all injured in one chopping action. The attackers had obviously prepared and practiced for a long time," he said. Zhou Hongmei, director of the Medical Reform Office at the Yunnan Health Department, said a team of medical experts including 29 doctors had arrived in Kunming by Monday night. They have been working at the five hospitals treating victims of the attack. Chen Min, a Neurology Department nurse at Kunming First People's Hospital, said the department usually had seven nurses in the daytime and three at night. "But all the other nurses who were not on duty returned to the hospital voluntarily on Saturday night," she said. In the past three days, none of them had more than 10 hours of rest. "The crucial factor in saving lives in such incidents is treatment without delay," said Chai Wenzhao, associate director of the Intensive Care Unit in the Peking Union Medical College Hospital. Chai has participated in many emergency rescue efforts. He said that the victims will need psychological counseling once their physical injuries have been dealt with, because the emotional impact of such an incident can be severe. Four psychologists from Anding Hospital in Beijing have begun treating some of the victims. What's the best title of the passage?

The sharp drop in world oil prices has led oil companies in the United States to dismiss thousands of workers. Some companies have also delay new oil drilling and exploration projects. The drop in oil prices has also affected small service companies and even stores that do business with oil companies in big producer states like Texas. But the drop in oil prices has not been bad for everyone. Oil platform workers are often called roughnecks. In Texas, many roughnecks have lost their jobs because of the drop in oil prices. The effect of falling prices has been worse in states like Alaska and North Dakota. That is because production costs are higher there than they are in the Eagle Ford area of south-central Texas. Adam Perdue is an economist at the University of Houston's Institute for Regional Forecasting. He has been studying the effect of falling oil prices in Texas. He says oil company exploration and production budgets are being cut between 10 and 50 percent, with most of them being cut by a third. He thinks the lower spending will affect the local economy. The economic slowdown will affect companies that manufacture pipes and other equipment for oil exploration and production. It will also have an effect on trucking companies that supply sand and chemicals, and other small businesses that serve the energy industry. But low oil prices are good for chemical companies.

Do you know how it is when you see someone yawn and you start yawning too? Or how hard it is to be among people laughing and not laugh yourself? Well, apparently it's because we have mirror neurons in our brains. Put simply, the existence of mirror neurons suggests that every time we see someone else do something, our brains imitate it,whether or not we actually perform the same action. This explains a great deal about how we learn to smile, talk, walk, dance or play sports. But the idea goes further: mirror neurons not only appear to explain physical actions they also tell us that there is a biological basis for the way we understand other people. Mirror neurons can undoubtedly be found all over our brains, but especially in the areas which relate to our ability to use languages, and to understand how other people feel. Researchers have found that mirror neurons relate strongly to language. A group of researchers discovered that if they gave people sentences to listen to (for example: "The hand took hold of the ball"), the same mirror neurons were as when the action was actually performed (in this example, actually taking hold of a ball). Any problems with mirror neurons may well result in problems with behavior. Much research suggests that people with social and behavioral problems have mirror neurons which are not fully functioning. However, it is not yet known exactly how these discoveries might help find treatments for social disorders. Research into mirror neurons seems to provide us with ever more information concerning how humans behave and interact .Indeed, it may turn out to be the equivalent for neuroscience of what Einstein's theory of relativity was for physics. And the next time you feel the urge to cough in the cinema when someone else does---well, perhaps you'll understand why. We can learn from the passage that mirror neurons _ .

We all know that the normal human daily cycle of activity is of some 7-8 hours' sleep alternating with some 16-17 hours' wakefulness and that the sleep normally coincides with the hours of darkness. Our present concern is with how easily and to what extent this cycle can be modified. The question is no mere academic one. The ease, for example, with which people can change from working in the day to working at night is a question of growing importance in industry where automation calls for round-the-clock working of machines. It normally takes from five days to one week for a person to adapt to a reversed routine of sleep and wakefulness, sleeping during the day and working at night. Unfortunately, it is often the case in industry that shifts are changed every week; a person may work from 12 midnight to 8 a.m. one week, 8 a.m. to 4 p.m. the next, and 4 p.m. to 12 midnight the third and so on. This means that no sooner has he got used to one routine than he has to change to another, so that much of his time is spent neither working nor sleeping very efficiently. The only real solution appears to be to hand over the night shift to a number of permanent night workers. An interesting study of the domestic life and health of night-shift workers was carried out by Brown in 1957. She found a high incidence of disturbed sleep and other disorders among those on alternating day and night shifts, but no abnormal occurrence of these phenomena among those on permanent night work. This latter system then appears to be the best long-term policy, but meanwhile something may be done to relieve the pressure of alternate day and night work by selecting those people who can adapt most quickly to the changes of routine. One way of knowing when a person has adapted is by measuring his body temperature. People occupied in normal daytime work will have a high temperature during the hours of wakefulness and a low one at night; when they change to night work the pattern will only gradually go back to match the new routine and the speed with which it does so parallels, broadly speaking, the adaptation of the body as a whole, particularly in terms of performance. Therefore, by taking body temperature at two-hour intervals throughout the period of wakefulness, it can be seen how quickly a person can adapt to a reversed routine, and this could be used as a basis for selection. So far, however, such a form of selection does not seem to have been applied in practice. The best solution for implementing the 24-hour working system seems to be _ .

A new study has found no evidence that sunscreen, commonly used to reduce the risk of skin cancer, actually increases the risk. Researchers from the University of Iowa based their findings on a review of 18 earlier studies that looked at the association between sunscreen use and melanoma . They said that they found _ in studies that had reported associations between sunscreen use and higher risk of melanoma. Most health experts believe that by protecting the skin from the harmful effects of the sun, sunscreen helps prevent skin cancer, which is increasing in incidence faster than any other cancer in the United States. But questions have been raised about sunscreen and whether it may have the opposite effect, perhaps by allowing people to remain exposed to the sun longer without burning. The researchers said that among the problems with some earlier studies is that they often failed to take into account that those people most at risk for skin cancer--people with fair skin and freckles , for example--are more likely to use sunscreen. As a result, it may appear that sunscreen users get cancer more often. The studies, which generally relied on volunteers to recall their sunscreen use, were also unable to prove how well the products had been applied, said the new study.

Mr. Knight was the manager of a hotel. One weekend all of the hotels in the city were full because there was a large meeting. On Friday, three men came into the hotel and asked for rooms. Mr. Knight said there were no rooms ready because of the meeting. The men were unhappy. Mr. Knight wanted to help them. He remembered that Room 418, a small room, was empty. He asked them if they could share a room. The three men said they would. Mr. Knight said the room would be thirty dollars; ten dollars for each person. Each man gave him the money and then went up to the room. Mr. Knight soon began to feel sorry. "Thirty dollars is a lot to ask as a price for that small room." he thought. He called his assistant over and said, "Here is five dollars. Take it to the men in Room 418. I asked too much for their room." The assistant took the money. While he was on the way there, he started to think, "How can three men divide five dollars? I'll give them each only one dollar and keep the two dollars for myself. The men will be happy to get something back. And Mr. Knight will never know." So the assistant returned one dollar to each man. Each man had at first paid ten dollars. After the assistant returned them one dollar each, each had actually(in fact) paid nine. There were three men. $9 3="$27." The assistant kept$2. $27+$2="$29." Where is the missing dollar?

The most frightening words in the English language are, "Our computer is down." You hear it more and more when you are on business. The other day I was at the airport waiting for a ticket to Washington and the girl in the ticket office said, "I'm sorry, I can't sell you a ticket. Our computer is down." "If your computer is down, just write me out a ticket." "I can't write you out a ticket. The computer is the only one allowed to do so." I looked down on the computer and every passenger was just standing there drinking coffee and staring at the black screen. Then I asked her, "What do all you people do?" "We give the computer the information about your trip, and then it tells us whether you can fly with us or not." "So when it goes down, you go down with it." "That's good, sir." "How long will the computer be down?" I wanted to know. "I have no idea. Sometimes it's down for 10 minutes, sometimes for two hours. There's no way we can find out without asking the computer, and since it's down it won't answer us." After the girl told me they had no backup computer, I said. "Let's forget the computer. What about your planes? They're still flying, aren't they?" "I couldn't tell without asking the computer." "Maybe I could just go to the gate and ask the pilot if he's flying to Washington, " I suggested. "I wouldn't know what gate to send you to. Even if the pilot was going to Washington, he couldn't take you if you didn't have a ticket." "Is there any other airline flying to Washington within the next few hours?" "I wouldn't know, " she said, pointing at the dark screen. "Only 'IT' knows. 'It' can't tell me." By this time there were quite a few people standing in lines. The word soon spread to other travelers that the computer was down. Some people went white, some people started to cry and still others kicked their luggage. The best title for the article is _ .

The defeat of Lee Sedol, the world's strongest Go player, by a Google artificial intelligence (AI) program, looks like another milestone towards a world where computers can do almost anything a human can. It is not. There are uncountable things that only a human can do, and that no computer seems close to. The problem is that the purely human things are not economically useful to anyone. The things that computers can be taught to do are by contrast economically fantastic. But even the most powerful programs are not human, just as a shovel . They have no feelings. What they have is power, but this power is growing at a rate that should frighten us all. It might be less frightening if computers were truly intelligent, but even the most powerful networks are less human than monstrous Martians . Their power will be used to make money for the firms that finance their development, and then for others quick and clever enough to take advantage of the new world. It is far more likely that they will increase inequality and still further remove the middle classes as we move towards an hourglass society in which everyone is either very rich or very poor and likely indebted. One of the ill effects of the spread of more intelligent computer networks is, at the same time, the spread of what might be called artificial stupidity. If AI is employed largely to replace unskilled labour, it is most productive when labour is kept unskilled or redefined that way. So much of the work in service industries is now simplified until it might be automated . And robots will never need pensions. AI is slowly reducing skilled work, like some forms of medical diagnosis , at the same time, as older doctors complain that the traditional human skills of diagnosis are falling out of medical training. The belief that everything worthwhile can be measured and then managed is far more damaging to humanity than the threat of artificial intelligence on its own. But no victory in complicated Go games can bring us closer to truly human-like computers. What does "artificial stupidity" in Paragragh 3 mean?

Twelve years ago, when I was 50,I wondered what 60 or 70 would be like? I looked around and saw only one style of living. It's not fair, I thought. Young people have so many styles to choose from, but older people have just one choice. So I decide to do something about it , something practical. I worked on my fitness by joining exercise classes in town. A few years later, my husband and I moved to a retirement community, and I wanted to teach aerobic classes. The community center wouldn't give me a room to teach in, so I had to walk around and find any available empty room. One day, the community center staff came to me and asked if I would help with the entertainment for a Hawaiian luau they were putting on. I said yes. Then I talked five other ladies into dancing with me. We performed the hula and a war chant and brought the house down. Someone had a camera and took pictures, and then sent them to our local paper. We got requests for more engagements, which in turn led to more publicity and yet more engagements. Soon we had invitations from all over the country. The Dancing Grannies were born! I think the real secret of the Dancing Grannies is out attitude. I was raised extremely poor ---no-food poor. If we wanted toys we had to make things up to play with ,so I learned early to be very creative. And you know,I think being poor was one of the best things that ever happened to me because I learned to look for treasures. That's what I'm still doing today--looking for the treasure in growing old. I'm getting better and better. It's true that _ have to be treated a bit differently, with a little care, but they still have a beauty of their own. What did the writer think of the living style of the older people when she was 50?

Air pollution by sources ranging from cooking fires to auto fumes contributed to an estimated seven million deaths worldwide in 2012, the UN health agency has said. "Air pollution, and we're talking about both indoors and outdoors, is now the biggest environmental health problem, and _ is affecting everyone, both developed and developing countries," said Maria Neira, the World Health Organisation's public and environmental health chief. Globally, pollution was linked to one death in eight in 2012, new WHO research found. The biggest pollution-related killers were heart disease, stroke, pulmonary disease and lung cancer. The hardest-hit regions of the globe were what the WHO labels Southeast Asia, which includes India and Indonesia, and the Western Pacific, ranging from China and South Korea to Japan and the Philippines. Together, they accounted for 5.9 million deaths. The global death toll included 4.3 million deaths due to indoor air pollution, chiefly caused by cooking over coal, wood and biomass stoves. The toll from outdoor pollution was 3.7 million, with sources ranging from coal heating fires to diesel engines. Many people are exposed to both indoor and outdoor pollution, the WHO said, and due to that overlap the separate death toll attributed to the two sources cannot simply be added together, hence the figure of seven million deaths. The new figure is "shocking and worrying", Ms Neira told reporters. When it last released an estimate for deaths related to air pollution, in 2008, the agency had put the figure related to outdoor pollution at 1.3 million, while the number blamed on indoor pollution was 1.9 million. But a change in research methods makes comparison difficult between the 2008 estimate and the 2012 figures, Neira said. In the past, for example, the WHO did not take into account the overlap between exposure to both forms, and only assessed urban pollution. Satellite imagery has made it easier to assess rural pollution, and new knowledge about the health impact of exposure has enabled a better count. "The risks from air pollution are now far greater than previously thought or understood, particularly for heart disease and strokes," said Neira. "Few risks have a greater impact on global health today than air pollution. The evidence signals the need for concerted action to clean up the air we all breathe." According to the WHO, some 2.9 billion people in poor nations live in homes that use fires as their principle method of cooking and heating. Carlos Dora, the WHO's public and environmental health coordinator, said that turned homes into "combustion chambers". Simple measures to stem the impact include so-called "clean cook stoves", which are a low-tech option, as well as improved ventilation, he said. Countries also need to rethink policies, Mr Dora said, pointing to the impact in the developed world of a shift to cleaner power sources, more efficient management of energy demand, and technical strides in the auto industry. He also said transport policies needed a shake-up. With air pollution having sparked a recent scare in France, leading to restrictions on car use and the temporary scrapping of public transport fees in Paris, Mr Dora said such measures could be applied in the longer term. "You can't buy clean air in a bottle," he said."The air is a shared resource. In order to breathe clean air, we have to have interventions in the areas that pollute air." The WHO said it planned by the end of this year to release a ranking of the world's 1,600 most polluted cities. The death toll in 2008 can hardly compare with that in 2012 because _ .

Have you ever wondered how and why a fall leaf changes color? We first have to understand what leaves are and what they do. Plants are the world's food factories. Plants take water from the ground and take CO2from the air. Plants use sunlight to turn water and CO2into glucose . Glucose is a kind of sugar. Using it as food, plants get energy and grow. Plants using sunlight to turn water and CO2into sugar is called photosynthesis . _ helps photosynthesis. It gives plants their green color. As summer ends and autumn comes, the days get shorter and shorter, and trees "know" to begin getting ready for winter. During winter, there is not enough light or water for photosynthesis. Trees rest during this time and live on the food they store during the summer. They begin to shut down their food -- making factories. As the green chlorophyII disappears from the leaves, we begin to see yellow and orange leaves. These colors have been in the leaves all the time. We just can't see them in the summer, because they are covered up by the green chlorophyII. The bright reds and purples we see in leaves are made mostly in autumn. In some trees, glucose is caught in the leaves after photosynthesis stops. Sunlight and the cool nights of autumn turn this glucose into a red color. The brown color of trees is made from waste left in the leaves. It is mixture of all these things. It makes the beautiful leaves during autumn. . Plants use sunlight to turn _ into sugar.

If you're looking for a fairly painless way to lose weight, researchers at Brigham Young University have a new solution for you: Put yourself on a regular sleep schedule. People who keep a regular sleep routine have a lower body fat than those who keep irregular sleep hours, says a new study. Led by Bruce Bailey, professor of exercise science, researchers followed 300 female college students aged 19 to 26, who were given activity trackers to watch their movements and activities, including waking and sleeping times . Researchers also measured their body composition before and after the one-week study period. What the researchers found: Body fat varied with sleep quantity. Women who slept between 8 and 8.5 hours a night had the lowest body fat. While those who slept less than 7 hours or over 9 hours had higher body fat. High quality sleep was associated with lower body fat while poor sleep was connected with higher body fat. Waking and going to sleep at the same time every day was most strongly linked with lower body fat. The difference in body weight was greater with more variation in sleep pattern. Women whose sleep patterns varied by 90 minutes a night had higher body fat than those whose sleep patterns varied by 60 minutes or less on average. The study followed up on a body of research conducted over the last few years that ties quality and quantity of sleep to weight loss and better weight control. While researchers don't know exactly how sleep schedules affect body weight and fat, other studies have shown that sleep has an effect on physical activity, appetite , and the hormones that control metabolism , and the signals that tell us we're full.

Students and Technology in the Classroom I love my blackberry -- it's my little connection to the larger world that can go anywhere with me. I also love my laptop computer,as it holds all of my writing and thoughts. Despite this love of technology, I know that there are times when I need to move away from these devices and truly communicate with others. On occasion, I teach a course called History Matters for a group of higher education managers. My goals for the class include a full discussion of historical themes and ideas. Because I want students to thoroughly study the material and exchange their ideas with each other in the classroom, I have a rule -- no laptop, iPads, phones ,etc .When students were told my rule in advance of the class, some of them were not happy. Most students assume that my reasons for this rule include unpleasant experiences in the past with students misusing technology. There's a bit of truth to that. Some students assume that I am anti-technology. There's no truth in that at all. I love technology and try to keep up with it so I can relate to my students. The real reason why I ask students to leave technology at the door is that I think there are very few places in which we can have deep conversions and truly _ complex ideas. Interruptions by technology often break concentration and allow for too much dependence on outside information for ideas. I want students to dig deep within themselves for inspiration and ideas. I want them to push each other to think differently and make connections between the course the material and the class discussion. I've been teaching my history class in this way for many years and the evaluations reflect student satisfaction with the environment that I create. Students realize that with deep conversation and challenge, they learn at a level that helps them keep the course material beyond the classroom. I'm not saying that I won't ever change my mind about technology use in my history class, but until I hear a really good reason for the change, I'm sticking to my plan. A few hours of technology-free dialogue is just too sweet to give up. Some of the students in the history class were unhappy with _ .

Zoo elephants don't live as long as those in the wild, according to a study sure to cause debate about keeping the giant animals on display. Researchers compared the life spans of elephants in European zoos with those living in Amboseli National Park in Kenya and others working on a timber enterprise in Buma. Animals in the wild or in natural working conditions had life expectancies twice than or more of their relatives in zoos. Animal care activists have urged in recent years to discourage keeping elephants in zoos, largely because of the lack of space and small numbers of animals that can be kept in a group. The researchers found that the _ life span for African elephants in European zoos was 16.9 years, compared with 56 years for elephants who died of natural causes in Kenya's Amboseli Park. Adding in those elephants killed by people in Africa lowered the median life expectancy there to 35.9 years. For the more endangered Asian elephants, the median life span in European zoos was 18.9 years, compared with 41.7 years for those working in the Burma Timber Enterprise. Median means half died younger than that age and half lived longer. There is some good news, though. The life expectancies of zoo elephants have improved in recent years, suggesting an improvement in their care and raising, but "Protecting elephants in Africa and Asia is far more successful than protecting them in Western zoos." There are about 1,200 elephants in zoos, half in Europe, researchers concentrated on female elephants, which make up 80 percent of the zoo population. One amazing thing was that Asian elephants born in zoos had shorter life spans that those brought to the zoos from the wild. Zoos usually lack large areas that elephants are used to in the wild, and that zoo animals often are alone or with one or two other unrelated animals, while in the wild they tend to live in related groups of 8 to 12 animals. In Asian elephants, baby death rates are two to three times higher in zoos than in the Burmese logging camps, and then, in adulthood, zoo-born animals die young. People are not sure why.

You may have heard all this before, but flu season is a great time to really start doing them. By following these pieces of advice, you might be able to keep yourself from getting sick and stop germs from spreading around and making other people sick. So your hands are very important. A lot of germs get in our bodies from there. Germs get on our hands and we put our hands in our eyes, noses, and, especially, our mouths. How to stop germs? Yeah, hand washing. You might pick up germs here and there. So when you wash your hands, you wash away germs. But how to wash your hands? That's easy: wash your hands with soap and warm water(not cold or hot). Don't forget to wash around your fingernails . This is one place germs like to be. Wash for about 15 to 20 seconds---about how long it takes to sing "Happy Birthday" twice.

The power of humor and laugher is numerous. They entertain us and make us feel good. But, above all, we have discovered that humor and laughter are the best medicine. They relieve pain, reduce stress and anxiety, and are anti-aging and longevity facilitators . They are extremely necessary for helping us to find and maintain a balance between life and work. However, they are slipping away from us. We have become far too serious. The only ones who still enjoy humor, laughter, fun and play to the fullest are young children. Children tend to laugh an average of 200 times a day. For adults, however, it is a totally different story. In the 1950s people laughed on average 18 times a day. Today, we are lucky if we average between 4-6 times a day. As a matter of fact, a recent study found that people laugh 6 more times in the presence of one person but 30 more times in a group of people. You can get a chuckle from jokes you get on the Internet, but it is not the same as belly jiggling laughter (a deep laugh) you get when you interact with others. Socializing with friends and relatives was much looked forward to. However, this is no longer the case. In fact, the majority of people can hardly find time, nor do they have the _ towards socializing outside home.
