It's 4 am, and Danilo C. Dequina is already awake. Holding a flashlight and a bucket, he is walking in the pre-dawn darkness along the shore of Old Poblacion Beach in the town of Maitum, Sarangani, in the far south of the Philippines. A few minutes later, he spots a patch of sand that appears to have been disturbed by a turtle. Dequina studies the area carefully, figuring out where the eggs have been buried, and then starts digging slowly. After clearing away several centimeters of sand, he uncovers a large group of eggs, roughly the size of ping-pong balls. He picks them up and puts them in the bucket. Dequina carries the eggs to his hatchery , some 50 meters away from the seashore. The hatchery is really just a sandy patch of land under the coconut trees enclosed by a black fence. It is here that he buries the turtle eggs he has collected. Today, Dequina scoops a hole, puts the eggs in it, and covers them with sand. After 45 to 70 days, the eggs will hatch. Dequina will then carry the hatchlings to the shore, and release them into the sea. He admits to feeling sorrow as he sets the hatchlings free -- most are hunted down by natural predators, and just one percent survive to adulthood. According to the Philippine Department of Environment and Natural Resources (DENR), eight species of sea turtles face extinction, including four that come to the shores of Sarangani to lay their eggs -- the Hawksbill, Olive Ridley, Loggerhead and Green Turtles. After learning about their plight , Dequina attended a DENR training session on turtle conservation and decided to take action. He helped the local government to set up the Pawikan Nesting Sanctuary next to his house in 2003. The hatchery drew the attention of the locals. "They started to change their attitudes towards sea turtles," 52-year-old Dequina says. "If they see turtle eggs, they will either bring them to me or inform me of the nesting places." Over the past ten years, more than 3,000 hatchlings have been released to the ocean. When Dequina finds turtle eggs along the shore, he will _ .

Dr.Michael Prager, a leading Botox expert, said that a growing number of women are developing something called "computer face".He also mentioned that professionals who worked long hours in front of a screen were ending up with saggy jowls , "turkey neck" and deep-set wrinkles on their forehead and around their eyes. The Botox expert said that, of all his clients, office workers were most likely to show premature signs of ageing."If you are one of the unfortunate people who frown while you are concentrating on the screen then, over time, you will inevitably end up with frown lines," Dr.Prager said."What is perhaps more surprising is the number of women with saggy jowls because they are sitting in one position for so long.If you spend most of the time looking down then the neck muscles shorten and go saggy, eventually giving you a second neck." Dr.Prager, who has a practice near Harley Street in London, said he encourages his clients to put a mirror next to their computer so they can see if they are frowning at the screen."When people are stressed or thinking hard about something, then they will often put on a 'grumpy face' without even knowing what they are doing.When my clients put a mirror next to their desk, they are often shocked by the angry, frowning face which stares back at them." He said, "The women I am seeing at the moment have only been using computers at work for the last decade or so.But women in their 20s have grown up with them and use them for every single task.I think the problem is going to become much, much worse.In another ten years, they could be looking quite awful." Dr.Prager said there were several simple steps which could avoid "computer face" such as regular screen breaks and stretching the neck muscles.And, of course, there was always Botox.He said that, after a couple of sessions of Botox, the habit of "grumpy face" could be broken. In what way do women develop a "computer face"?

For many men, the idea that they have a better sense of direction than women has been improved by a scientific study. Researchers from Norway scanned on the brains of volunteers as they completed navigation tasks to discover men are more skillful at finding their way because they use a separate part of their brain. According to lead researcher Dr. Cal Pintzka from the Norwegian University of Science and Technology (NTNU), men and women have different navigational strategies. Med use basic directions--the use of north, south, east and west--during navigation to a greater degree. Men's sense of direction was more effective. They quite simply got to their destination faster. "If they're going to the Students Society building in Trodheim, for example, men usually go into the general direction where it is located." Dr. Pintzka explained. Women usually orient themselves along a route to get there, for example, go past the hairdresser and then up the street and turn right after the shore. The study shows that using the basic directions is more efficient because it is a more flexible strategy. The destination can be reached faster because the strategy depends less on where you start. Meanwhile, the study also shows both men and women use large areas of the brain when they navigate, but some areas were different. The man used the hippocampus more, whereas women use their frontal areas to a greater extent. That degrees with the fact that the hippocampus is necessary to make use of basic directions. Losing one's sense of direction is one of the first symptoms in Alzheimer's disease. Understanding how men and women use different brain areas and strategies to navigate, researchers will be able to enhance the understand of the disease's development, and develop coping strategies for those already affected. What strategy do men usually take to find a place?

Nick Vujicic was born with no arms or legs, but the brave 32-year-old man, plays football and golf, swims, and surfs. Nick has a small foot on his left side, which helps him balance and enables him to kick. He uses his one foot to type, write with a pen and pick things up between his toes. "I call it my chicken drumstick ," joked Nick, "I'd be lost without it. When I get in the water I float because 80 per cent of my body is lungs and my drumstick acts as a propeller." When Nick was born his father was so shocked he left the hospital room to vomit. His _ mother couldn't bring herself to hold him until he was four months old. "It was so hard for them, but right from the start they did their best to make me independent. My dad put me in the water at 18 months and gave me the courage to learn how to swim. " said Nick. Throughout his childhood Nick dealt with the typical challenges. At the age of seven, Nick tried out some specially designed electronic arms and legs, in hope that he would be more like the other kids. During the short trial period of the electronic arms and legs, Nick realized that even with them, he was still unlike his peers at school, and they turned out to be much too heavy for Nick to operate, affecting his flexibility quite significantly. "When I was 13 I read a newspaper article about a disabled man who had managed to achieve great things and help others," said Nick, "I realized why God had made us like this - to give hope to others. It was so inspirational to me that I decided to use my life to encourage others and decided to be thankful for what I do have, not get angry about what I don't." "I tell people to keep on getting up when they fall and to always love themselves," he said. "If I can encourage just one person then my job in this life is done." By now, he has visited 35 different countries, touring the world as a motivational speaker. Which of the following statements is true?

Science can't explain the power of pets,but many studies have shown that the company of pets can help lower blood pressure and raise chances of recovering from a heart attack,reduce loneliness and spread all-round good cheer. Any owner will tell you how much joy a pet brings.For some.an animal provides more comfort than a husband/wife.A 2002 study by Karen Allen of the State University of New York measured stress 1evels and blood pressure in people-half of them pet owners-while they performed 5 minutes of mental arithmetic or held a hand in ice water.Subjects completed the tasks alone,with a husband/wife,a close friend or with a pet.People with pets did it best.Those tested with their animal friends had smaller change in blood pressure and returned most quickly to baseline heart rates.With pets in the room,people also made fewer math mistakes than when doing in front of other companions.It seems people feel more relaxed around pets,says Allen,who thinks it may be because pets don't judge. A study reported last fall suggests that having a pet dog not only raises your spirits but may also have an effect on your eating habits.Researchers at Northwestern Memorial Hospital spent a year studying 36 fat people and their equally fat dogs on diet-and-exercise programs;a separate group of 56 people without pets were put on a diet program.On average,people lost about 11 pounds,or 5% of their body weight.Their dogs did even better,losing an average of 12 pounds,more than 15%of their body weight.Dog owners didn't lose any more weight than those without dogs but,say researchers,got more exercise overall-mostly with their dogs--and found it worth doing.

People are overweight for many reasons, the most important one of which is that they eat the wrong foods, get the wrong types of calories per meal, and they also eat meals at the wrong time each day. Food is more powerful than any weight loss pill, because the food that you eat can either make you thin or fat. This is true because your body is like an engine, and it only needs certain foods at certain intervals each day. Low-calorie Diets Do Not Work The reason people cannot lose weight by starving themselves is that their metabolism will detect any major drop in calories and it will then adjust itself by burning fewer calories each day. That is the reason why you can eat 1,000 calories per day and not lose any weight, while your friends can eat 2, 500 calories per day and not gain any weight. Low-fat Diets Do Not Work Many people in today's society are buying mostly low- fat or non-fat food at the grocery store. Everybody knows how much fat is inside the food they buy. However, people are getting fatter than ever before by doing this. They are not losing weight by changing to this low-fat lifestyle. Losing weight has nothing to do with these things. One of the most important things you can do to control your weight is to eat the proper foods, such as fruit and vegetables, eat them at the right time, and exercise every day. If people make this a habit, they will lose weight. What is the main reason why people are overweight according to the author?

Of all the websites,one that has attracted attention recently is _ .Most of this attention has come from the media and tells every reason why the website should be shut down.The threat of internet predators is indeed a tough reality,but shutting down the site is not the answer.If _ were shut down,another site would quickly take its place.Therefore,the right way is to teach teens how to use the site safely and educate them about who may be predators and how to avoid them. The key to staying safe on the Internet is to make sure that your profile is secure.The simplest way is to change the privacy setting on your profile to "private", which protects your information so that only the people on your friend list can view it.Although this is effective,it is not perfect.Predators can find ways to view your profile if they really want to,whether through hacking in or figuring out their way onto your friend list.Thus,you should never post too much personal information.Some people actually post their home and school addresses,date of birth,and other personal information, often letting predators know exactly where they will be and when.The most information that is safe is your first name and province.Anything more is basically inviting a predator into your life. Another big issue is photos. I suggest completely skipping photos and never posting a photo of a friend online without asking permission. Most importantly, never,under any circumstances,agree to a real-life meeting with anyone you meet online.No matter how well you think you know this person, there are no guarantees that they have told the truth.But you could feel free to chat with people you meet on the site, but just remember that not everyone is who they say they are.Hopefully,the next time you edit your profile,you'll be more informed about the dangers of internet predators and take the steps to defend yourself. Kids can avoid web predators successfully by_.

Think stars don't move? Think again! When you look at the sky at night, the stars may appear to stay in the same place. But stars are always on the move--they are just so far away that the movement is hard to see. But some stars move in ways that appear to be strange to be real. In 2005, astronomer Warren Brown found one of these space oddities . It was located on the outer edge of the Milky Way, the galaxy we live in. The star was speeding away like nothing he'd ever seen. "It seemed unbelievable. No star in the galaxy has a speed like that," Brown remembers. "I thought, oh my goodness, I have something kind of special here." No one had ever seen a star like this one. What does a scientist do when the results don't make sense? Brown didn't give up. Instead, he kept looking. And he kept finding more of these strange and speedy stars, called _ stars. Hyper means "above" and velocity has to do with speed. He and his team just found six more of these "above speed" stars, bringing to the total of 16. And, he says, he's found even more, and is just waiting for the scientific community to confirm them. In 2005, astronomer Warren Brown found _ .

Many years ago, my dad was diagnosed with a serious heart condition. He was unable to work a steady job. He would be fine for a while, but would then fall suddenly ill and have to be admitted to the hospital. He wanted to do something to keep himself busy, so he decided to volunteer at the local children's hospital. My dad loved kids. It was the perfect job for him. He ended up working with the seriously ill children. He would talk, play, and do arts with them. One of his kids was a girl with a rare disease that paralyzed her from the neck down. She couldn't do anything, and she was very depressed. My dad decided to try to help her. He started visiting her in her room, bringing paints, brushes and paper. He stood the paper up, put the paintbrush in his mouth and began to paint. He didn't use his hands at all. All the while he would tell her, "See, you can do anything you set your mind to." At the end of the day, she began to paint using her mouth, and she and my dad became friends. Soon after, the little girl was sent home because the doctors felt there was nothing else they could do for her. My dad also left the children's hospital for a little while because he became ill. Some time later after my dad had recovered and returned to work, in came the little girl who had been paralyzed, but this time she was walking. She ran straight over to my dad and hugged him really tight. She gave him a picture she had done using her hands. At the bottom it read: "Thank you for helping me walk." My dad would cry every time he told us this story and so would we. He would say sometimes love is more powerful than doctors, and my dad - who died just a few months after the little girl gave him the picture - loved every single child in that hospital.

It's true that many dads in the wild aren't interested in parenting, but there are some that work pretty hard to give their little ones a good start. Maybe one of these dads will make you remember your own dad! The male giant water bug doesn't seem to mind a heavy load on his back for his kids. The female puts about 100 to 150 eggs on the back of the male, and then she leaves. Once the female is gone, the male has to look after the eggs. It usually takes one to two weeks for the eggs to hatch. The father giant water bug jumps around to make sure the growing eggs get enough air and water. All this time he can't fly because of the weight of the eggs growing rapidly on his back. Now let's turn to the male stickleback fish. When the mother leaves after laying her eggs, the father tends his young. If the young fish go too far away, their father helps with their safe return by carrying them back in his mouth. The male stickleback looks after all his young -- as many as 100 -- until they can live on their own. A similar example can be found in emperor penguins living in cold areas. The male emperor penguin goes without food while looking after his egg until it hatches. For about 62 to 67 days, the egg stays on top of the father's feet, in very cold temperatures that drop down to -39deg C. As a result, the father may lose nearly 50 percent of his body weight while waiting for his baby penguin to be born! During the hatching period, the male emperor penguin _ .

It was something she had dreamed of since she was five. Finally, after years of training and intensive workouts, Deborah Duffey was going to compete in her first high school basketball game. The goals of becoming an outstanding player and playing college ball were never far from Deborah's mind. The game was against Mills High School. With 1 minute and 42 seconds left in the game, Deborah's team led by one point. A player of Mills had possession of the ball,and Deborah ran to guard against her. As Deborah was running to block the player, her knee went out and she fell down on the court in burning pain. Just like that, Deborah's season was over. After suffering the bad injury, Deborah found that, for the first time in her life, she was in a situation beyond her control. Game after game, she could do nothing but sit on the sidelines watching others play the game that she loved so much. Injuries limited Deborah's time on the court as she hurt her knees three more times in the next five years. She had to spend countless hours in a physical clinic to receive treatment. Her frequent visits there gave her a passion and respect for the profession. And Deborah began to see a new light in her life. Currently as a senior in college, Deborah focuses on getting a degree in physical treatment. After she graduates, Deborah plans to use her knowledge to educate people how to best take care of their bodies and cope with the feelings of hopelessness that she remembers so well. How did Deborah feel when she first hurt her knee?

With about 10 million new iPhone 6s ordered in the initial days on the market, a lot of old iPhones are bound to be thrown into the dustbins. Sure, you could sell, donate or recycle your old iPhone, but you probably will not. And there are better things to do with it. One creative example: At the Missouri University of Science and Technology, a biology class is making old iPhones into microscopes. Using less than $10 worth of supplies, the old phones are mounted onto a lens and can magnify an object to 175 times its size. Here are 5 smart-and-cheap uses for old iPhones. Music for your car Take your music library on the road. Some cars are equipped with docking ports for iPhones and have dashboard screens so you can choose your favourite music hands-free. Or you can just use the cigarette lighter for power. Remote Control Televisions, speakers and other devices now have apps that allow users to make their iPhones into fashionable remotes. Carm Lyman, 42, of Napa, California, transformed his iPhone 4 into a remote for his household sound system after his iPhone 5 arrived. Lyman can control the audio levels and activate speakers in various parts of his home as well as access different music services. Cookbook No need to go through recipe books or hunt around for other devices when you have a kitchen iPhone. Download a cookbook app, such as My Recipe Book (99 cents) or Big Oven (free), and just leave the device on the kitchen counter. It takes up almost no space and will hold far more recipes than any book. Baby Monitor Sure, you can spend $100 or more on a baby monitor, or you can just set your old iPhone up to watch video of your baby in real time as well as hear and even talk to him or her. Cloud Baby Monitor ($3.99) also allows parents to receive the signal on a wireless network or on WiFi so they do not have to be within a certain number of feet of the monitor. Vehicle Tracker Whether you need to find your car if it is stolen, record where you have traveled, or spy on your teenage driver, the built-in GPS in your phone can be used as a tracking device. An app like InstaMapper ($2.99) lets you watch the vehicle in real-time and have a record of it. Keep in mind that the phone can still dial 911, even if it does not have cellphone service, Smith said. You can also use your old phone as a back-up in case your new model suffers irreparable harm. That said, the battery of a phone that sits in a drawer unused could be exhausted to the point where it is no longer workable. Who will probably benefit the most from an old iphone?

Mandara seemed to know something big was about to happen. So she let out a yell, caught hold of her 2-year-old daughter Kibibi and climbed up into a tree. She lives at the National Zoo in Washington, D.C. And on Tuesday, August 23rd, witnesses say she seemed to sense the big earthquake that shook much of the East Coast before any humans knew what was going on. And she's not the only one. In the moments before the quake, an orangutan let out a loud call and then climbed to the top of her shelter. "It's very different from their normal call," said Brandie Smith, the zookeeper. "The lemurs (monkey-like animals of Madagascar) will sound an alarm call if they see or hear something highly unusual." But you can't see or hear an earthquake 15 minutes before it happens, can you? Maybe you can -- if you're an animal. "Animals can hear above and below our range of hearing," said Brandie Smith. "That's part of their special abilities. They're more sensitive to the environment, which is how they survive." Primates weren't the only animals that seemed to sense the quake before it happened. One of the elephants made a warning sound. And a huge lizard ran quickly for _ . The flamingoes (a kind of bird) gathered before the quake and stayed together until the shaking stopped. So what kind of vibrations were the animals picking up in the moments before the quake? Scientist Susan Hough says earthquakes produce two types of waves -- a weak "P" wave and then a much stronger "S" wave. The "P" stands for "primary". And the "S" stands for "secondary". She said she thinks the "P" wave might be what set the animals off. Not all the animals behaved unusually before the quake. For example, Smith says the zoo's giant pandas didn't jump up until the shaking actually began. But many of the other animals seemed to know something was coming before it happened. "I'm not surprised at all," Smith said. According to Brandie Smith, _ .

If you want to learn anything at school, you need to listen to your teachers. Unfortunately, millions of kids can't hear what their teachers are saying. And it's not because these students are _ . Often, it's the room's fault. Building architecture and building design can createecho -filled classrooms that make hearing difficult. Children with hearingimpairments suffer most from noisy classrooms. They sometimes can't hear questions that other students ask in class. Compared with kids with healthy hearing, they have a harder time picking up new vocabulary words by hearing them in talking. Even kids with normal hearing have a harder time in the classroom when there's too much noise. Younger children in particular have trouble separating important sounds - like a teacher's voice - from background noise. Kids with learning disabilities and speechimpediments and kids for whom English is a second language also have a harder time learning in noisy situations. In recent years, scientists who study sound have been asking schools to reduce background noise, which may include loud air-conditioners and pipes. They're also targeting outdoor noises, such as highway traffic. Noise reduction is a big deal. Why? Because quieter classrooms might make you smarter by letting you hear your lessons better. "It's so obvious that we should have quiet rooms that allow for access to the lesson," says Dan Ostergren, a hearing scientist. "Sometimes it surprises me that we spend so much time discussing this topic. I just want to go. Why is this hard for anyone to grasp?" Who is most affected by noisy classrooms?

Don't drive your kids to school. Let them ride a bike to school. In England 8.3 million children travel to school every day. It is reported that only a small number of pupils cycle to school (under 2%), although one in three children would actually like to. Experts say that to stay healthy, children need at least one hour of moderate exercise every day. But only six out of ten boys and four out of ten girls get that. One of the reasons is that parents have developed a habit of driving their children to school when they could just walk or ride a bike to school. Teachers often say that children who walk or ride a bike to school are more ready to listen to their classes, ask and answer questions in class than those driven by car, and the school journey is a good chance for children to learn about road safety and other life skills. Also, for many children, riding a bike is more fun than going to school by car. Most parents know the benefits . Then what's stopping them from letting their kids ride a bike? Safety is the number one worry for them. But actually riding a bike is not as dangerous as parents think it is. When you decide to buy a bike, you should be aware that a bike that is too big or too small is dangerous. Don't try to get a bike that your child will "grow into". Get the right size in good working order. Generally, 20-inch wheels are on bikes for 5-8 year olds; 24-inch wheels are for 9-11 year olds; 26-inch wheels are suitable for those over 11, and some older children should even take bikes with 28-inch wheels, but the main thing is that the bike fits your child. This passage is mainly written for _ .

The German shepherd runs off and noses around in the grass of Kenya's Laikipia Plateau. "OK, Oakley," the dog's handler orders, "Find it!" Oakley sniffs until he comes to a bush, then stops, sits, and looks up at his handler. She bends to see what he has found: the waste of an endangered African wild dog. "Good dog!" she praises. The handler pulls a tennis ball from her pocket. Oakley jumps for his reward. "He doesn't actually want the waste," says Aimee Hurt, a founding member of the U.S.-based group Working Dogs for Conservation. Hurt is in Kenya to train both Oakley and his handler. "He finds it so he can play with his ball. We're the ones who want the waste." Detection dogs are sometimes taught to locate actual animals. Black-footed ferrets have been studied with their help. But more often the dogs learn to locate the waste of creatures such as bears, wolves and mountain lions. What the dogs find provides scientists with data about a species. Scientists can use the DNA collected from animal waste to identify individuals, sex, and population sizes -- all without ever seeing the animal itself. "It can take years to gather this kind of information if you have to trap animals," Hurt explains. Waste analysis might make a huge difference when wild species are accused of attacking domestic livestock . Hurt says, "A good detection dog will find the waste so we can see what the animal is actually eating." This may help reduce problems between people and wildlife. Oakley is interested in finding the waste because _ .

Rome-Doctors and medical groups around the world last weekend reacted with strong opposition to the news that an Italian specialist is _ cloning the first human baby. DL Severino Antinod,who is the head of a hospital in Rome,has been referred to in an Arab newspaper as claiming that one of his patients is eight weeks pregnant with a cloned baby. Antinori refused to comment on the reports,but in March 2001 he said he hoped to produce a cloned embryo for implantation within two years.So far seven different kinds of mammals have already successfully cloned,including sheep,cats and most recently rabbits. Doctors showed their doubt and were strongly opposed although they admit that human cloning would finally come true unless there was a world wide ban on the practice. Professor Rudolf Jaenisch of the Whitehead Institute for Biomedical Research at the Massachusetts Institute of Technology says,"I find it astonishing that people do this where the result can be foretold that it will not be a normal baby.It is using humans as guinea pigs.It makes people feel sick."But Ronald Green,director of the Ethics institute at Darmouth College in the US,said it is unlikely that an eight-week-old pregnancy would lead to a birth. So far all cloned animals have suffered from some different serious disorders,many of them dying soon after their births. Doctors are opposed to human cloning because they are worried about the welfare of the cloned child if there is one. "There are no benefits of cloned human begins,just harm."said Dr.Michael Wilks of the UK. Which is the best title for the embryo?

Once Dr. Mellinkoff invited me to join him at the hospital to discuss interesting cases(, ) with his students.The case at hand was a Guatemalan man, aged 34, who had a fever and many other medical problems.His condition was not improving, and there was not much hope he would live. Dr.: Mellinkoff asked to see the patient.He introduced himself in Spanish and, in a very gentle voice, asked how he felt.The patient smiled and said everything was all right.Then the doctor asked if he was able to eat.The patient said that he had no desire to eat. "Are you getting food you like?" The patient said nothing. "Do you get the kind of food you have at home?" The answer was no. The doctor put his hand on the man's shoulder and his voice was very soft. "If you had food that you liked, would you eat it?" "Yes, yes," the patient said. The change in the patient's appearance couldn't have been more obvious.Nothing was said, but it was easy to tell that a message had been sent and had also been received. Later, the doctor asked why the Guatemalan man wasn't getting food he could eat.One of the students said, "We all know how difficult it is to get the kitchen to make special meals." "Suppose," the doctor replied, "you felt a certain medicine was absolutely necessary but that our hospital didn't carry it, would you accept defeat or would you insist the hospital meet your request?" "I would probably insist," the student said. "Very well," the doctor said."You might want to try the same method in the kitchen.It won't be-easy, but I can help you.Meanwhile, let's get some food inside this man as fast as possible, and stay with it.Or he'll be killed by hunger.By the way, there must be someone among you who can speak Spanish.If we want to make real progress, we need to be able to talk with him." Three weeks later.Doctor Mellinkoff told me that the Guatemalan man had left the hospital under his own power.It takes more than medicine to help sick people; you also have to talk to them and make them comfortable. The patient had no desire to eat because _ .

Scientists will put some robot fish into the sea near Spain this year. These robot fish will help people find out the pollution in the water. If the robot fish are able to finish their work successfully, the team of scientists hopes the fish will be used in rivers, lakes and seas around the world. The robot fish are about 1.5 meters long. There is a detector in their bodies. It can find the pollution in the water, and then the robot fish will eat part of it. They can "swim" for eight hours in the sea freely and send back information to people on the beach. After their energy runs down, they will go back to the beach by themselves. There are five robot fish altogether. Each costs about 29,000 dollars. They are part of a three-year project between engineering company BMT Group and Essex University in southeastern England. ,. (2,10) What will the robot fish do if they swim in the water?

Millions of young people are writing blogs . Millions of others are reading them. The word "blog" is a short way of saying Web log. Many popular Web sites now offer free, easy ways to create personal Web pages and fill them with writings and pictures. Web sites called "Face book" and "My Space" are some of the most popular blog sites for young people. Blogs offer young people a place to show their writings and feelings. They can also be helpful to connect young people with others. But blogs can become dangerous when they are read on the Internet by millions of people all over the world. Recent studies show that young people often tell their names, age and where they live on the Internet. That may not be safe for them. This personal information puts them in danger when found out by dangerous people who want to hurt them. Students can also get into trouble when they put information about others on their blogs. As a result, many schools don't allow using blogging web sites on school computers. Many schools have also begun teaching parents about the web sites. Parents should know what their children are doing online and should read their blogs to make sure they are not giving out personal information. One way to keep away from these problems is to use programs so that blogs can be read by "friends only." people can read the website only if they know a secret word chosen by the blogger.

When was the last time your family sat down together to have a dinner? The speed at which we live today no longer allows for slow eating habits. Most people work long hours. There is lots of fast food and eating out is now on the increase. Often, food is eaten in front of the television in silence, or a child eats alone in front of the computer. When I was a child, every evening around the same time, one of the children would be asked to set the table, and then we'd go and wash our hands: before the meal. This was the time of day when we would talk about our day at school. But now things have changed a lot. A family environment plays an important role for children in learning to communicate with others and understanding table manners, such as waiting for others to finish before leaving the table and not speaking with a mouth full of food. Parents' likes and dislikes of a certain food will also influence a child's own likes and dislikes. Studies have shown that children who often eat with their families have better results at school than children who eat with their families less than twice a week. Regular meal times give children the chance to discuss their problems with family members. They can also learn to respect others around the table. Talking to your children over dinner is the best way of having their-trust. Children learn good eating habits from their parents at a very young age. Family meals are important. Prepare them for your children. Which would be the best title of the passage?

A couple of weeks ago, my 12-year-old daughter, Ella threatened to take my phone and break it. "At night you'll always have your phone out and break you'll just type," Ella says. "I'm ready to go to bed, and try to get you to read stories for me and you're just standing there reading your texts and texting other people," she adds. I came to realize that I was ignoring her as a father. Ella isn't the only kid who feels this way about her parent's relationship with devices. Catherine Steiner-Adair, a psychologist at Harvard, wrote The Big Disconnect: Protecting Childhood and Family Relationships in the Digital Age. For her book, Steiner-Adair interviewed more than 1,000 kids from the ages of 4 to 18. She talked to hundreds of teachers and parents. One of the many things that knocked my socks off, " she says, "was the consistency with which children -- whether they were 4 or 8 or 18 or 24-- talked about feeling exhausted and frustrated or mad trying to get their parents' attention, competing with computer screens or iPhone screens or any kind of technology." A couple of years ago, my daughter got a laptop for school. And because she was becoming more independent, we got her a phone. We set up rules for when she could use the device and when she'd need to put it away. We created a charging station, outside her bedroom, where she had to plug in these devices every night. Basically -- except for homework-- she has to put it all away when she comes home. Steiner-Adair says most adults don't set up similar limits in their own lives. "We've lost the boundaries that protect work and family life,'' she says. "So it is very hard to manage yourself and be present in the moments your children need you.'' After my daughter's little intervention ,I made myself a promise to create my own charging station. To plug my phone in-- somewhere faraway -- when I am done working for the day. I've been trying to leave it there untouched for most of the weekend We can infer from the text the author _ .

Coffee is one of the most popular drinks throughout the world today. In fact, according to some estimates, over 30% of all adults in the world drink coffee at least once a day on the average. Coffee contains a kind of drug called caffeine. Caffeine is a chemical that stimulates the nerves of the body. Drinking coffee tends to make people a little bit more awake--at least for a short time--because of this stimulating effect on the nervous system. A cup of coffee has, on the average, about 3% caffeine in it. One story of the discovery of the coffee plant relates to this effect of caffeine. According to the story, coffee was discovered in East Africa. The story says that coffee was first found by a goat farmer named Kaldi. This was about the year 850. Kaldi was leading his animals through the mountains and the goats were stopping repeatedly to eat the plants near the path. Suddenly, some of the goats started jumping up and down in a very strange way. Kaldi figured out that the goats were acting this way because of the plants they were eating. Kaldi himself tried eating some of the green beans that the goats had been eating. He, too, felt the stimulating effect of the beans. Kaldi wanted to prove what had happened, so he picked some of the beans and took them back to the village, where he told his story. The green bean got the name "Kaffa" and later "coffee" because the beans were discovered in a place called Kaffa in Africa. Then for years, people used to eat a few of the green Kaffa beans when they were in the mountains and needed extra energy to do their work. It was later found that the coffee beans could be picked and then dried until they turned brown, and then they could be stored. If the beans were dried and stored, they could be used at any time. How did the goats react after eating the plants?

A person who is deaf when he is born is usually dumb as well. There may be nothing wrong with his mouth and tongue, but he cannot speak. This is because he cannot hear people, so he has nothing to imitate . He may try to make sounds himself, but cannot hear his own voice. However, even though he finds it difficult to speak and cannot hear, he can learn to read. Nowadays such persons can also be taught to speak because we have modern methods and equipment, but we did not have these when Helen Keller was born. Even with modern methods and equipment, however, it is not easy for deaf children to learn to speak, though most of them succeed. When a child is deaf and blind as well, it becomes much more difficult, though it is possible. Helen Keller was born in 1880. She became very ill at the age of nineteen months. Medical knowledge was not as great then as it is now. She did not die but lost her sight and hearing. As a result, she became dumb as well. Her parents did their best to teach her, but she couldn't speak by the age of six. Then, in 1887, a teacher, Miss Sullivan, came to live with her. Miss Sullivan herself had been blind. She had been partly cured. Though she could not see very well, she was not blind. Helen was a difficult pupil at first, but in a month Helen had learned how to understand signs and how to make them herself. At last in spite of her great difficulties, Helen learned to read, write and speak, even though she was deaf and blind. She even went to college and had full education. She wrote many books, and though other people have written books about her, her own books are the ones that best explain how it feels to be deaf, dumb and blind. Her best book is The Story of My Life. Perhaps you have read it. Though it was written in 1902, it is still a very interesting book. Even if you have not read it, you may have heard of Helen Keller. A person who is deaf at birth is also dumb because _ .

Running like the wind, roaring like thunder, tigers have long been feared and respected as a king of the animal world. But last week a report said that there are no more than 30 wild tigers left in south China. This was the conclusion of a team of scientists from China's State Forestry Administration and the World Nature Fund. The South China tiger, also known as the Chinese tiger, is native to southern China. In the 1950s, there were over 4,000 tigers found in mountain forests in the country. But due to the destruction of their natural habitat and uncontrolled hunting, it has been pushed on to the list of the world's top ten most endangered species. Sixty-six of the big cats can be found in the cages of a dozen zoos around China. But they are nothing like their wild cousins. They have lost their natural skills such as hunting and killing. If they were set free they could not look after themselves. "Breeding has damaged the quality of the species," said Pei Enle, deputy director of the Shanghai Zoo. To reintroduce the species into the wild, the country started a programme to send five to ten young tigers to South Africa. Four of them have already arrived. Progress has been made as two elder tigers have recovered some of their instincts and can hunt wild animals by themselves at the African base. "South Africans are very experienced in reintroducing big animals to the wild. The country has very good natural conditions for the tigers to learn in," said Lu Jun, office director of the National Wildlife Research and Development Centre. "We tried in Fujian Province, but it was not successful as there was not a complete eco-chain and there was a lack of space." The tigers should return to China in 2009 when the reservations in Fujian are ready. What is the main reason for the South China tiger becoming one of the world's top ten most endangered species?

A "blogger" is a person who writes on an Internet computer Web site called a "blog ".The word "blog" is a short way of saying Web log, or personal Web site. Anyone can start a blog, and they can write about anything they like. There are millions of blogs on the Internet today. They provide news, information,advertisements, advice and ideas for many people who read them. They contain links to other Web sites. And they provide a place for people to write about their ideas and react to the ideas of others. A research company called Perscus has studied more than 300 Web logs. It says that blogs are most popular with teenage girls. They use them to let their friends know what is happening in their lives. The study also says that more than 100,000 bloggers stopped taking part in the activity after a year. However, some people develop serious blogs to present political and other ideas. For example, the Republican and Democratic parties in the southern state of Kentucky recently started their own blogs. And American companies are beginning to use blogs to advertise their products. At the same time, some long-standing blogs have ended. Last week, blogging leader Dave Winer closed his free blog service "weblogs. com". He says the site became too costly to continue. He started the blog four years ago. And thousands of people had written on it. They are now upset because they did not know that the site was closing. One blog that is still going strong is called Rebecca's Pocket. Rebecca Blood created the Web-site in 1999. She wrote about the history of blogs on the site. That article led to a book called "The Weblog Handbook". It has been translated into four languages so far. Ms. Blood says Rebecea's Pocket gets about 30,000 visitors a month. She writes about anything and everything -- politics, culture and movies. She recently provided medical advice. And she wrote about how to prevent people from stealing money from on -line bank accounts. Dave Winer closed his "weblogs. Com" because _ .

If you're a male and you're reading this, congratulations: you're a survivor. According to a survey, you're more than twice as likely to die of skin cancer than a woman, than nine times more likely to die of AIDS. Assuming you make it to the end of your natural term, about 78 years for men in Australia, you'll die on average five years before a woman. There're many reasons for this -- typically, men take more risks than women and are more likely to drink and smoke--but perhaps more importantly, men don't go to the doctor. "Men aren't seeing doctors as often as they should," says Dr. Gullotta. "This is particularly so for the over-40s, when diseases tend to strike." Gullotta says a healthy man should visit the doctor every year or two. For those over45, it should be at least once a year. Two months ago Gullotta saw a 50-year-old man who had delayed doing anything about his smoker's cough for a year. "When I finally saw him it had already spread and he finally died from lung cancer," he says. "Earlier detection and treatment may not have cured him, but it would have prolonged his life." According to a recent survey, 95% of women aged between 15 and early 40s see a doctor once a year, compared to 70% of men in the same age group. "A lot of men think they can never defeated," Gullotta says. "They only come in when a friend drops dead on the golf course and they think, 'Geez, if it could happen to him, ...'" Then there's the ostrich approach. "Some men are scared of what might be there and would rather not know," says Dr, Ross Cartmill. "Most men get their cars serviced more regularly than they service their bodies," Cartmill says. He believes most diseases that commonly affect men could be addressed by preventive check-ups. Regular check-ups for men would inevitable place strain on the public purse, Cartmill says. "But prevention is cheaper in the long run than having to treat the diseases. Besides, the ultimate cost far greater; it's called premature death." What does Dr. Ross Cartmill mean by " the ostrich approach" (Line 1, Para. 9)

A recent report has suggested that air pollution in our big cities could be as damaging to our health. The report put forward practical tips that city people can take to reduce their exposure to city air pollution. Quite a lot, it turns out. * Watch where you walk Avoid walking along busy streets and thoroughfares , instead choosing side streets and parks. because pollution levels can fall by a factor of 10 just by moving a few metres away from the main source of the pollution - exhaust fumes. " Don't walk behind smokers, and walk on the windward, side of the street where exposure to pollutants can be 50% less than on the leewardside. * Pavement sense When you're crossing a road, stand well back from the kerb while you wait for the lights to change. Every metre really does count when you are close to traffic. As the traffic moves, the gases can disappear in just a few seconds, particularly if the wind is up, which means holding your breath during this period can make a difference, silly as that might sound. Besides, cross the road as quickly as possible. And once you're over, continue along the pavement as far away from the kerb as possible. * Where to sit on the bus Sitting on the driver's side of a bus can increase your exposure by 10% compared with sitting on the side nearest to the pavement. And sitting upstairs on a double-decker can reduce your exposure too. It's difficult to say whether travelling on an underground train is better or worse than taking the bus, but the air pollution on underground trains tends to be less toxic by weight than that found at street level. * Wear a mask Masks can be a good thing, but they only make a difference if they fit tightly and are cleaned regularly. Even the slightest gap to allow you to breathe more easily will _ any advantages. Worse, if you fail to clean or change the mask regularly, something dangerous can form on the mask. So the air you breathe is dirtier rather than cleaner. Which of the following is NOT TRUE according to the passage?

Normally, about 10 percent of the hair on your head is resting (not growing). After a few months, the resting hair falls out and new hair begins to grow in its place. The growing time can last from 2 to 6 years. During the growing period, hair will gain about 1 centimeter a month. It is normal to experience hair loss every day. Some people experience too much hair loss from a variety of causes. Most people _ believe that hair loss is caused by things like stress, scalp ,or wearing hats. With the exception of stress, none of these factors has been proven to be a cause of hair loss. Stress is also not very likely unless you have experienced extreme physical or psychological suffering. This hair loss also doesn't last long. The real cause of hair loss lies with hormonal problems. Hair loss occurs when male or female hormones are out of balance. An imbalance of hormones is usually genetic and cannot be cured. Male and female-pattern baldness is the most common form of hair loss. This is caused by a hormone called DHT, which helps in sexual development. An increase in DHT in a grown-up can lead to hair loss. There are also other causes of hair loss. Blood-thinners, some kind of medicines, and an excess of vitamin A, have all been shown to increase hair loss in certain people. Infections of the scalp can cause hair loss as well as certain diseases like diabetes. If a man experiences extreme physical suffering, he _ .

We are all busy talking about and using the Internet, but how many of us know the history of the Internet ? Many people are surprised when they find that the Internet was set up in the 1960s. At that time, computers were large and expensive. Computer networks didn't work well . If one computer in the network broke down, then the whole network stopped. So a new network system had to be set up. It should be good enough to be used by many different computers. If part of the network was not working, information could be sent through another part. In this way computer network system would keep on working all the time. At first the Internet was only used by the government, but in 1970s, universities, hospitals and banks were allowed to use it, too. However, computers were still very expensive and the Internet was difficult to use. By the start of the 1990s, computers became cheaper and easier to use. Scientists had also developed software that made " surfing " the Internet more convenient. Today it is easy to get on-line and it is said that millions of people use the Internet every day. Sending e-mail is more and more popular among students. The Internet has now become one of the most important parts of peoples' life. _ made "surfing" the Internet more convenient .

When couples get married, they usually plan to have children. Sometimes, however, a couple can not have a child of their own. In this case, they may decide to adopt a child. In fact, adoption is very common today. There are about 60 thousand adoptions each year in the United States alone. Some people prefer to adopt _ , others adopt older children, some couples adopt children from their own countries, and others adopt children from foreign countries. In any case, they all adopt children for the same reason ---- they care about children and want to give their adopted child a happy life. Most adopted children know that they are adopted. Psychologists and child-care experts generally think this is a good idea. However, many adopted children or adoptees have very little information about their biological parents. As a matter of fact, it is often very difficult for adoptees to find out about their birth parents because the birth records of most adoptees are usually sealed. The information is secret so no one can see it. Naturally, adopted children have different feelings about their birth parents. Many adoptees want to search for them, but others do not. The decision to search for birth parents is a difficult one to make. Most adoptees have mixed feelings about finding their biological parents. Even though adoptees do not know about their natural parents, they do know that their adopted parents want them, love them and will care for them. Why is it difficult for adoptees to find out about their birth parents?

Many people believe that you lose the ability to learn new languages as you get older. Language experts, however, will tell you that you're never too old to learn a new language. As you get older, it can be more difficult to learn a new language, though. Children and adults learn new languages in different ways. For children, language is their life. They study for thousands of hours every year, because they need to learn languages to become part of their communities. Adults, on the other hand, are already part of a language community. Learning a new language means becoming part of another language community, and adults rarely get the chance to practice as much as young children do. Moreover, children learning a new language are expected to make mistakes. This gives them freedom when learning to be daring and confident. Adults, however, often feel pressured to be perfect when learning a new language. This can discourage many people and make it even harder to learn a new language. When young children learn a new language, they come to see various languages as a "normal" part of society. This mindset helps them embrace learning a new language without feeling like they're doing something unusual or "too hard". So if you want to learn a new language, go for it! It's never too late to learn a new language. If you're older, it may take more work, but it can be done. If you're a young child, though, now is the time to step out and learn a new language! What may make it hard for the old people to learn to a new language?

"Over the years the unthinkable has become thinkable and today we sense we are close to being able to alter human heredity oe#)." These were the words of David Baltimore of the California Institute of Technology, on December 1st, when he opened a three-day meeting in Washington to discuss the morality and use of human gene editing. Dr Baltimore is an old hand at these sorts of discussions, for he was also a participant in the Asilomar conference, in 1975, which brought scientists together to discuss a safe way of using the then-new tcchnology of recombinant DNA, and whose recommendations influenced a generation of biotechnology researchers. Four decades on, the need for a similar sort of _ has arisen. The International Summit on Human Gene Editing has been held by the national scientific academies of three countries -- America, Britain and China. They are particularly concerned about whether gene editing should be used to make heritable changes to the human germ line, something Dr Baltimore described as a deep and troubling question. Like those of Asilomar, the conclusions of this meeting will not be binding. But the hope is that, again like Asilomar, a mixture of common sense and peer pressure will create a world in which scientists are trusted to regulate themselves, rather than having politicians and civil servants do it for them. The meeting is being held against a backdrop of rapid scientific advance, Since 2012 research into a new, easy-to-use editing tool called CRISPR-Cas9 has blossomed. This technique involves a piece of RNA (a chemical messenger, which can be used to recognise a target section of DNA) and an enzyme called a nuclease that can snip unwanted genes out and paste new ones in. Public interest was aroused in April, when Chinese scientists announced they had edited genes in non-viable ( ) human embryos, and again in November when British researchers said they had successfully treated a one-year-old girl who had leukaemia ( ), using gene-edited T-cells. T-cells are part of the immune system that attack, among other things, tumour cells. The researchers altered T-cells from a healthy donor to encourage them to recognise and kill the patient's cancer, to make them immune to her leukaemia drug, and to ensure they did not attack her healthy cells. In another recent development, a firm called Edit as Medicine, which is based in Cambridge, Massachusetts, has said it hopes, in 2017, to start human clinical trials of CRISPR-Cas9 as a treatment for a rare genetic form of blindness known as Leber congenital amaurosis . Though other companies are already testing gene-editing therapies, these employ older, clunkier forms of the technology that seem likely to have less commercial potential. Moreover, researchers at the Broad Institute, also in Cambridge, said this week that they had made changes to CRISPR-Cas9 which greatly reduce the rate of editing errors -- one of the main obstacles to the technique's medical use. On the subject of germ-line editing, Eric Lander, the Broad's head, told the meeting it would be useful only in rare cases and said it might be a good idea to "exercise caution? before making permanent changes to the gene pool. The need for caution is advice that might also be heeded by those pursuing work in animals other than people, and in plants -- subjects not being covered by the summit. This passage is most probably a _

It's a popular belief that a fish's memory lasts for only seven seconds. It may seem sad to think that they don't remember what they've eaten or where they've been, and they don't recognize you or any of their friends -- every moment in their life would be like seeing the world for the first time. But don't be so quick to feel sorry for them. A new study has found that fish have a much better memory than we used to think. In fact, certain species of fish can even remember events from as long as 12 days ago. In the study, researchers from MacEwan University in Canada trained a kind of fish called African cichlids to go to a certain area of their tank to get food. They then waited for 12 days before putting them back in the tank again. Researchers used computer software to monitor the fish's movements. They found that after such a long break the fish still went to the same place where they first got food. This suggested that they could remember their past experiences. In fact, scientists had been thinking for a long time that African cichlids might have a good memory. An earlier study showed that they behaved aggressively in front of certain fish, perhaps because they remembered their past "fights". But until the latest findings, there was no clear evidence. Just as a good memory can make our lives easier, it also plays an important part when a fish is trying to survive in the wild. "If fish are able to remember that a certain area contains safe food, they will be able to go back to that area without putting their lives at risks," lead researcher Trevor Hamilton toldLive Science. For a long time, fish were placed far below chimpanzees, dolphins and mice on the list of smart animals. But this study has given scientists a new understanding of their intelligence. Which of the following is TRUE according to the passage?

At the U.S. Open championships in Flushing Meadows, New York last week, the United States Tennis Association (USTA) held an unusual youth press conference . I say "unusual" because the main idea wasn't to promote the sport for young children. Yes, there was a youth tennis exhibition in which a group of fresh-faced kids from the area showed off their well developed skills. They used junior racquets and larger, low-pressure balls on a half-size tennis court-a way the organization supports as a means to help children have early success and stick with the game. But the event's real purpose was to help parents realize the importance of introducing kids to all kinds of athletic programs rather than focusing specially on one. _ may sound like something easy to do, but it's not. In today's achievement-oriented ( ) environment, children are being pushed to specialize in a single sport-whether it's tennis, hockey, soccer, or gymnastics - at ever-younger ages. Tom Farrey, executive director of the nonprofit Aspen Institute Sports & Society Program, says year-round sports programs are now offered down to age 5, too early an age for a child to limit himself or herself to a single activity. While parents naturally want the best for their child, they are being pressured by coaches to let him or her stick with one thing. The result: More kids under age 12 are suffering injuries or, worse, burnout. According to the Aspen Institute's report, Project Play, fewer kids today are staying involved with sports than five years ago, partly because of forced specialization. Today's children are already on track to live shorter, less healthy lives than their parents because of obesity and related diseases, and this trend is only worsening matters. Multi-sport participation, however, leads to better performance (because kids get a chance to develop different sets of skills ) and greater enjoyment of the game, says Farrey. The headlining athletes at the event repeated the idea that having kids do more than one sport is a plus (good for them). What's the best title for the passage?

We've used the wind as an energy source for a long time. The Babylonians and Chinese were using wind power to pump water for irrigating crops 4,000 years ago, and sailing boats were around long before that. Wind power was used in the Middle Ages, in Europe, to grind corn, which is where the term "windmill" comes from. We can use the energy in the wind by building a tall tower, with a large propeller on the top. The wind blows the propellor round, which turns a generator to produce electricity. We tend to build many of these towers together, to make a "wind farm" and produce more electricity. The more towers, the more wind, and the larger the propellors, the more electricity we can make. It's only worth building wind farms in places that have strong, steady winds, although boats and caravans increasingly have small wind generators to help keep their batteries charged. The best places for wind farms are in coastal areas, at the tops of rounded hills, open plains and gaps in mountains - places where the wind is strong and reliable. Some are offshore. To be worthwhile, you need an average wind speed of around 25 km/h. Most wind farms in the UK are in Cornwall or Wales. Isolated places such as farms may have their own wind generators. In California, several "wind farms" supply electricity to homes around Los Angeles. The propellors are large, to obtain energy from the largest possible volume of air. The blades can be angled to cope with varying wind speeds. Some designs use vertical turbines , which don't need to be turned to face the wind. The towers are tall, to get the propellors as high as possible, up to where the wind is stronger. This means that the land beneath can still be used for farming. We can infer from the passage that _ .

You've heard of 3D printing from newspaper and TV programs. It can "print" in plastic, metal, nylon, and over a hundred other materials. 3D printing technology has been around since the 1980s, it was not widely used until the early 2010s. The first working 3D printer was created in 1984 by Chuck Hull. 3D printers use many different types of technologies, but they all share one thing in common: they create a three-dimensional object by building it layer , by continuing layer, until the whole object is completed. Imagine a baker lay down each layer one at a time until the whole cake is formed. 3D printing is somewhat similar, but just a bit stricter. How can 3D printers work so well? The most important thing-a program, a 3D printer also needs to have instructions for what to print from a computer. It needs a file as well. The file which is a Computer Aided Design (CAD) paper is created with the use of a 3D modeling program. The program creates a paper that is sent to the 3D printer. Along the way, software pieces the design into hundreds, or more likely thousands of layers. The 3D printer builds up one layer at a time, from the bottom to the top, until the object is done. 3D printings can be used for making many kinds of things such as machine parts, daily life objects, even human organs using a person's own cells. Nowadays, Marc. Dillon founds a project which deals with many world famous paintings like Leonardo da Vinci's Mona Lisa, Van Gogh's Sunflower with 3D technology. This project helps the blind people enjoy the fantastic art through touching. In order to provide a good user experience, these 3D paintings have special instruments which can tell people what they touch. Which of the following is true?

Is your TV connected to the Internet? What about your chair or your fridge? It is possible that they are not. But in the future, most things in your home may be connected, as the so-called "Internet of things" is developing. The Internet of things may be coming sooner than you think. It is reported that during his speech earlier this year, Samsung CEO BK Yoon spent a lot of time talking about the Internet of things. He said that five years from now,every Samsung product will be part of the Internet of things, whether it's a washing machine or a vacuum cleaner . So, how do household objects that are part of Internet of things work? Well, think of a usual chair. When connected to the Internet, the chair warms up when it knows that the user has just walked into the room and is feeling cold. An Internet-connected camera, like a smart-home camera, could help people feel safer in their homes. It can recognize people's faces, and even can see when someone passes by in the dark. Then it can 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 Review, whether companies are connecting dog food bowls or security systems to the Internet, there may be problems. For example,many early connected-home devices don't have much built-in security, which means they could be hacked ,In addition, it could be difficult to get these devices to work together because they are made by different companies. To fight this, many companies have joined the Open Interconnect Consortium, which had 45 members by late 2014. So, picture this: you walk in through the front door of your home. The temperature changes to make you feel comfortable after a long day at school. Your favorite music starts playing for you. Do you think that this would be a good thing? It may happen sooner than you think. What's the problem about the Internet of things?

The deadliest Ebola outbreak in recorded history is happening right now. The outbreak is unprecedented both in the number of people who have gotten sick and in the geographic scope. And so far it's been a long battle that doesn't appear to be slowing down. Ebola is both rare and very deadly. Since the first outbreak in 1976, Ebola viruses have infected thousands of people and killed roughly killed 60 percent of them. Symptoms can come on quickly and kill fast. The current outbreak started in Guinea sometime in late 2013 or early 2014. It has since spread to Sierra Leone and Liberia, including some capital cities. And one infected patient traveled on a plane to Nigeria, where he spread the disease to several others and then died. Cases have also popped up in various other countries throughout the world, including in Dallas and New York City in the United States. The Ebola virus has now hit many countries, including Guinea, Liberia, Sierra Leone, Nigeria, Senegal, and the United States. The virus, which starts off with flu-like symptoms and sometimes ends with bleeding, has infected about 6,500 people and killed more than 3,000 since this winter, according to the World Health Organization on September 30, 2014. There are some social and political factors contributing to the current disaster. Because this is the first major Ebola outbreak in West Africa, many of the region's health workers didn't have experience or training in how to protect themselves or care for patients with this disease. Journalist David Quammen put it well in a recent New York Times article, "Ebola is more dangerous to humans than perhaps any known virus on Earth, except rabies and HIV. And it does its damage much faster than either." Hopefully, researchers are working to find drugs, including a recent $50 million push at the National Institutes of Health. And scientists are working on vaccines , including looking into ones that might be able to help wild chimpanzees, which are also susceptible to the disease. The first human Ebola vaccine trial is scheduled to start in the spring of 2015. The Ebola virus was brought to Nigeria by _ .

To what degree can a computer achieve intelligence?The answer to this question may lie in a newly-developed US computer program called Smarter Child and the Internet. If you ran into Smarter Child online, you would be surprised at this kid's huge memory. It can recite many facts. For example, Smarter Child knows every baseball player in every team this season. He knows every word in the dictionary and the weather in every major city areas across the US. However, if you ask Smarter Child other questions, you get strange answers. A question about Smarter Child's age returns, "One year, 11 days, 16 hours, 7 minutes, and 47 seconds!" Asking where he lives gets, "In a clean room in a high-tech building in California." Smarter Child uses the vast information on the World Wide Web as his memory bank. To answer questions about spelling, for instance, Smarter Child goes to American Heritage Dictionary online. For the weather, he visits www.intellicast.com. Some scientists believe that by joining the many systems of the Internet, an artificial being with the combined knowledge of, say, Albert Einstein, Richard Nixon and Britney Spears could be born. However, if Smarter Child wants to think and learn on his own like the boy-computer David in the movie A. I. Artificial Intelligence, he must solve two problems. The first is that computers find it difficult to read web pages because the files are sorted in different ways. That's why programmers need to tell Smarter Child where to look for the weather. It would be a much more difficult task to let him find it himself. Another problem is that while Smarter Child can process information more exactly and faster than any human, he lacks common sense--a basic grounding of knowledge that is obvious to any young child. It is probably most difficult for Smarter Child to_.

Ask anyone what is the most difficult part of changing their lifestyle habits and they are most likely to say, "Staying motivated." But a 36-year-old professor from Carnegie Mellon University claims it may have the answer in the form of robot weight loss coach that dishes out daily health advice and encouragement. Autom is the work of Intuitive Automata, a company based in Sha Tin which claims to be a pioneer in commercial socially-interactive robots. The robot, which stands around 38 centimeters tall, has a head that swivels , blue eyes, and a touch screen which allows the user to input information daily about exercise and diet Its creators say Autom will have a daily conversation with its user lasting up to five minutes, giving feedback and encouragement.Over time, it will interact more with the user as it gathers more information about them. Cory Krdd, a research team manager with the Federal Emergency Management Agency claims research has shown that people find robots a more reliable source of information than on-screen-based character. In a controlled study in Pittsburgh City Council, 15 dieters were given Autom for six weeks. Another 15 received a touch-screen computer with identical software and 15 were given a paper log.The study found, people using the robot are more likely to stick with their diets longer, in fact twice as long as those using just a paper log. "While not one person among the computer or paper groups continued past six weeks, most who had Autom did not want to give her back at the conclusion of the study," he said. The bottom line is that a robot creates a more powerful and long-lasting relationship with the user than a character on the screen. Autom is expected to go on sale later this year in the United States for around $500.A robot which speaks and understands Cantonese and Mandarin in addition to English according to the demands is also being developed. What can we infer from the passage?

My life began much like most children before my father left us. I grew up without knowing what a father was and no one was there to teach me how to behave and how to tell right from wrong. Because of this, I developed problems with alcohol and spent seven years as a boy in the street, before ending up in a rehab clinic when I was 20. Inside I met my counselor , Bill, and he taught me a lot of things. The main thing was the gift of giving. It was the night before an important test and I was very nervous.

He stopped then and looked at me in a serious but loving way and said, "No, you won't." He told me that I didn't owe him anything and he was doing this because he wanted to. He then told me something that has followed me to this day, "One day you'll be around someone and they'll need a coffee, and you'll be able to buy it for them. That's how you can pay me back."

Cities with high levels of homeownership--in the range of 75%, like Detroit and St. Lous -had on average considerably lower levels of economic activity and much lower wages and incomes. Far too many people in financial problems are trapped in homes they can't sell, unable to move on to new centers of opportunity. The cities and regions with the lowest levels of homeownership--in the range of 55% to 60% like Los Angeles and New York--had healthier economies and higher incomes. They also had higher levels of happiness and well-being. I was shocked to read these interesting points that Richard Florida made in his recent article. Let me try to understand. The people in Detroit and St. Louis are less happy than the people in New York, and Los Angeles. And, the reason is because of home ownership rates? First, to compare them to New York City (the economic capital of the world), Los Angeles (the entertainment capital of the world) seems unfair. Most people in almost any other city in the world might be less happy! Next, let's try a different way of determining whether renters are happier than homeowners. Why don't we ask them? Fannie Mae's National Housing Survey 2010 reported: 75% of current renters believe owning a home makes more sense. 67% plan to buy a home at some point in the future. When they asked current renters for the major reason to buy a house, these were their answers (they could pick several answers): 78% said it was a good place to raise children. 75% said because they would feel safe. 70% said because you have control your own space. If you believe renters are happier, you would also have to believe the majority enjoy living in a less safe environment, which wouldn't be a good place to raise children and would be a place where they have less control of their space. ks5u Which of the following is a fact?

[
"People in Los Angeles earn high incomes because of its low homeownership rate.",
"New York's low homeownership rate increases people's happiness levels.",
"Detroit's high level of homeownership causes its economic problems.",

Have you ever walked outside thinking it was one temperature but quickly discovered it felt colder? That is because of the "wind chill" effect. Wind chill is how cold people and animals feel when they are outside, not the actual temperature on the thermometer . It is based on how quickly your body loses heat when it is exposed to wind and cold. When the wind is strong, your body quickly loses heat, making the temperature of your skin drop. When scientists first started calculating wind chill, they used research conducted in 1945 by explorers to Antarctica who measured how quickly water froze outside. But water freezes faster than exposed skin, so the wind chill index based on that data wasn't accurate. In 2001, the US government began to measure wind chill more precisely by testing how quickly people's skin froze. Twelve volunteers were placed in a chilled wind tunnel. Equipment was stuck to their faces to measure the heat flow from their cheeks, forehead, nose and chin while they walked three miles per hour on a treadmill . The experiment revealed how quickly exposed skin can be damaged, particularly unprotected areas like your fingers, toes, the tip of your nose and your ear lobes. In fact, 40 percent of your body heat can be lost through your head! Signs you might have frostbite are when the skin turns white or pale and you lose feeling in that area. The information collected from the volunteers helped scientists work out the math to compute wind chill. It involves wind speed and air temperature. If, for example, the temperature outside is zero degrees Fahrenheit and the wind is blowing at 15 miles per hour, the wind chill is calculated at 19 degrees below zero. At that wind chill temperature, exposed skin can freeze in 30 minutes. You can find a calculation table at www.nws.noaa.gov/om/windchill/index.shtml. Experts advise in cold weather that you wear loose-fitting, lightweight, warm clothing, worn on top of each other. Air caught between the clothes will keep you warm. The best cold-weather coats have head coverings made of woven material that keep out water. So next time the temperature drops and you want to play outside, listen to your parents when they tell you to wrap up warm! According to the text, wind chill _ .

Who wants to carry a _ bag to school? No children. Nobody wants one shoulder to be lower than the other, and paining too. In India, most of us would look at the reduction of textbooks as a way out. But in a country like America, there are always more choices. A company called Goreader has created a "school bag" which is the size of a laptop computer, weighing about 2.5kg. The Goreader has a colour screen and can "hold" all the textbooks that a student may need, says a report in "The Asian Age" newspaper. The company plans to work closely with the publishers of test books so that these books can be supplied on the Internet. All the students will have to download their textbooks. Making notes and marking important parts of a lesson can be done just as lots of students have done on their textbooks before. At present, the plan is being tested out in a university. Richard Katzmann, the owner of the company is having his creation tested at Chicago's DePaul University, where he studied. Does that mean it is goodbye to the newspaper, and the smell of the black ink? The writer may think that Americans have a _ way to solve the problem.

If you're training for a marathon, a proper plan for water intake is important. Of course, there's the risk of dehydration . But athletes now know they can also get into trouble by drinking too much. Too much water intake can lower levels of sodium in the blood. The death of a 28-year-old woman following the Boston Marathon caught the attention of many runners and led to new research. Experts advise long distance runners to replace the liquids they sweat out. Their goal is to try to keep someone from not getting dehydrated by more than 2 percent of their body weight. One technique for deciding how much water you need is to get the exact numbers. Runners have to weigh themselves before and after a run to determine how much water they've lost. If their weight drops by more than 2 percent, they have not drunk enough water. Hyponatremia occurs when runners drink so much water that blood salt levels drop off. A study published last year tested 488 runners who completed the Boston Marathon and found 13 percent of them had dangerously low blood salt levels. The first sign that runners may notice is slightly swelling in the hands. They can't get their rings off, and then they might feel sick. They may not remember where they are. In fact, most runners get enough salt to get back to normal levels by eating just one meal after a run. Contrary to the old advice that runners should drink as much as they can to prevent dehydration, the new research has shown that the body is a remarkable machine that actually tells you via thirst when you need water. What conclusion can we draw from the passage?

"Taking much salt during a run can avoid swelling in the body.",
"Either too much or too little of water intake is harmful.",

The great white shark is the largest shark and is probably the most well-known and feared shark. The great white shark is gray or bluish above and white below. The largest Great Whites can reach lengths of 22 feet and weigh up to 5,000 pounds. The Great White has massive teeth, which are positioned in rows. When the Great White attacks, it bites its prey and shakes its head back and forth. The serrated teeth act as a saw and literally tear the victim apart. Actually the Great White Shark often swallows many of its own teeth in an attack. Great Whites employ several hunting skills depending on the prey. Most of the time, the shark will remain still underwater before attacking its prey from underneath. In the case of hunting some kinds of seals, the impact of the shark is so powerful that it knocks both the shark and the seal clear out of the water. With larger prey such as elephant seals, the shark will simply take a huge bite out of it and wait for it to bleed to death. When hunting dolphins, the shark will attack from above, to avoid detection from the dolphin's echolocation. Interestingly, a Great White Shark has never been observed giving birth. However, pregnant females have been caught. The Great White Shark is known to be ovoviviparous. Females give birth to eight or nine pups that are already about five feet in length upon birth, which is different from other egg-laying animals. Despite the fear of Great White Sharks, at least in part generated by Steven Spielberg's 1975 movie, Jaws, Great White Sharks do not target humans as prey. Most attacks are attributed to mistaken identity. Sharks can easily mistake humans for seals. Many human injuries caused by Great White Sharks are cases of test-biting. If a shark is unsure about a floating object, it often gives it test bite to determine what kind of object it is. While such bites do little damage to buoys and other objects, they obviously can cause serious damage on the human body. Which aspect is not mentioned in the passage?

People who cannot tell all colors apart are said to be color-blind. Most color-blind people can see yellows and blues, but confuse reds with green. It is very rare for a person to be blind to all colors, but they may see everything in shades of black, white and gray. It is interesting to point out that many color-blind people don't even realize that they are color-blind, they don't know that the colors they are seeing and naming are not the actual colors that people with normal vision can see. This can be dangerous when a color-blind person confuses the red and green of a traffic light. Color blindness is thought to be inherited and although doctors have tested color blindness, there is no cure to treatment for it. A color-blind person _ .

A letter to Edward, a columnist Dear Mr Expert: I grew up in an unhappy and abusive home. I always Promised myself that I'd get out as soon as possible. Now, at age 20,I have a good job and a nice house, and I'm really proud of the independence I've achieved. Here's the problem: several of my friends who still live with their parents wish they had places like mine -- so much so that they make mine theirs. It started out with a couple of them spending the weekends with me. But now they seem to take it for granted that they can shou up any time they like. They bring boyfriends over, talk on the phone and stay out forever. I enjoy having my friends here sometimes-- it makes the place feel comfortable and warm-- but this is my home, not a party house. I was old enough to move out on my own, so why can't I seem to ask my friends to respect my privacy ?

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. What should you drink in order to reduce the risk of depression?

Studies show farmland in Africa is often lacking in important nutrients. But researchers say combining different farming methods may help. Since the world food crisis several years ago, researchers have directed more of their attention to small farms. Most farms in areas south of the Sahara Desert are only about one or two hectares. One of the goals is to increase production without necessarily clearing more land to grow additional crops. American researchers say that can happen with greater use of an agricultural system called perennation. It mixes food crops with trees and perennial plants - those that return year after year. Mr. Reganold, who is with Washington State University, says poor soil may have resulted from years of weathering that washed away many nutrients. He says some farmers may have done more harm than good. He estimates that up to two billion dollars worth of nitrogen, phosphorous and potassium is lost from African soil each year. The scientist says the word perennation defines three systems that are already used in Africa. The oldest of the three is called evergreen agriculture. This is where farmers plant trees with their crops. John Reganold says farmers in Africa have been doing this for sixty years, but it seems to be growing in popularity. The method is gaining widespread use in countries such as Niger, Burkina Faso, Malawi and Zambia. The trees are planted among maize, millet or sorghum crops. They not only add nitrogen to the soil through their roots, but also through their leaves when they fall off and break down. At other times of the year, the trees can protect plants from strong sunlight. Mr. Reganold was one of three researchers who wrote a report about perennation. It was published in the journal Nature. We can infer from the passage that _ .

Qi Haoran, a Junior One student, was quite busy over the past winter vacation - and not just with homework.Qi, together with 10 other classmates made a volunteer group to call on people to join the Clean Your Plate Campaign . The 11 students went to many restaurants and told people the importance of saving food. "Excuse me, do you know that 950 million people around the world still haven't got enough to eat? Could you please not waste food?" They would say this kind of thing hundreds of times every day. The Clean Your Plate Campaign began on the Internet in January.It _ people to reduce food waste. China in these years had serious problems with wasted food.CCTV reported in January that the food Chinese people waste every year is enough to feed 200 million people for a year. Chinese people are well known for being hospitable and generous.Many even feel that they lose face if their guests have eaten all their food. Luckily the campaign has got the support of many.In a restaurant in Xinjiang, the owner gives the guests who have eaten up all that they ordered a sticker.People can enjoy a free meal when they have 10 stickers.More than 750 restaurants in Beijing have begun to offer smaller dishes and encourage their guests to take leftovers home. To reduce food waste is a big task, and it needs time.It's important that everyone does their bit, just like Qi.Did you finish your meals today?

Since around the later part of the 1950s, society started to realize that tobacco cigarettes caused health problems. As research progressed along with increasing numbers of people that developed lung cancer, emphysema, and other smoking related illnesses, cigarette smoking has become less accepted and popular. Unfortunately, the nicotine contained in cigarettes is one of the most addictive substances on the planet and makes quitting smoking one of the hardest things to do. In 2003, Chinese pharmacist, Hon Lik invented the electronic cigarette as a safer, and cleaner way to breathe in nicotine after his father, a heavy smoker, passed away from lung cancer attributed to smoking tobacco cigarettes. Hon Lik applied for his first patent on the electronic cigarette in 2003 and afterwards introduced e-cigs to the Chinese market in the following year through his employer, Golden Dragon Holdings. Golden Dragon Holdings later changed the company's name to "Ruyan" in order to better match the company's name(Ruyan means "almost like smoke")to the new product. Since the renaming, the Ruyan company has continued e-cigarette development and grown to be one of the largest global e-cig manufactures. Dr.Sam Han, CEO of Cixi E-CIG Technology, Inc, Ltd. also has a number of e-cig related inventions, including four patents in the United States and two in China that are electronic cigarette and e-liquid technology related. Similar to Hon Lik's father. Dr. Han was a heavy smoker for more than 40 years before beginning to work on electronic cigarette technologies in order to help himself and others make the shift to vapor smoking. Dr.Han continues to market and conduct R&D in e-cig related techonologies to this date. After the successful deployment of Ruyan and Cixi E-CIG electronic cigarettes in China and Asia, the products started to be sold in significant quantities on the Internet.

If you see a person carelessly throw a cigarette to the ground, what are you likely to think? If you hate people throwing things on the ground, you might think, "That person shouldn't litter." If you are a smoker, you might think, "I would sure like a cigarette right now." Most likely, though, you are not thinking, "That unused cigarette butt could be used to make something amazing!" That is, unless you are a creative scientist. If you are, you may see potential--a possibility--where others simply see trash . That is just what has happened in South Korea. The spirit of invention can hit at the strangest times and in the most unusual places. In South Korea, it happened near a trash can. Kin Gil-Pyo is with the Seoul National University. He says he saw people throwing away cigarette butts, which got him thinking. He began wondering if something useful could be made from them. He and other researchers found a way to convert cigarette butts into materials required for high-performance batteries. Kim Gil-Pyo says they looked closely at used cigarette filters , the parts of cigarettes smokers put into their mouths. Filters are made of a material called "cellulose acetate ." Mr. Kim explains that cellulose acetate can be made into another material: carbon. The pieces of cellulose acetate, known as fibers, are changed through a one-step burning process. After this, they are turned into an energy storage material. But why use carbon? Carbon has many qualities that seem to make it the perfect material. Carbon has a high surface area. It conducts electricity well. It also stays stable, unlikely to change, for a long time. And carbon does not cost a lot. All these qualities make it the most popular material for making super-capacitors . Super-capacitors are good at storing energy. They have high-power mass, or density . They require only a short time for recharging. And they have a long lifecycle. Super-capacitors are used in products such as laptop computers and cell phones. They are also used in industrial energy converters, like wind turbine machines. Combining carbon and super-capacitors seems like a perfect marriage. Kim Gil-Pyo tells the Reuters News Agency that cigarette butts could affect the economy is a huge way. They could prove to be a low-cost source of carbon material. They are so cheap that smokers throw them to the ground. And you don't get much cheaper than that. Super-capacitors made from carbon _ .

Snowflakes! You can catch them on your tongue or use them to make a perfect snowball. But have you ever thought about taking pictures of them? Ken Libbrecht did. He is a physics professor from California. Although the weather in California is usually warm and sunny, Ken's hobby is taking pictures of snowflakes. He travels to cold areas like Alaska and Canada to find snowstorms and take pictures of the snowflakes. "They are often beautiful, and every snowfall brings new surprises," says Ken. Ken takes pictures of snowflakes with a high-quality digital camera. He uses a microscope to make the tiny snowflakes larger. To get the best images, Ken built a special photo-microscope just for snowflakes. He collects flakes by letting them fall onto a piece of foam board . The pictures must be taken outdoors, so Ken wears lots of clothes to stay warm. But his fingers often get cold, because it's difficult for him to take pictures of a tiny snowflake with gloves. Each snowflake has shapes and patterns that make it as unique as a person's fingerprint. The hobby of snowflake photography is also unique. Next time a snowstorm blows through your town, take a closer look at the flakes before you gather them into a snowball. See if you can notice their unique patterns. Millions of snowflakes are waiting for you! ,. Which of the following statements is TRUE?

How can you find out what is going on inside a person's body without opening the patient's body up? Regular X rays can show a lot. CAT scans can show even more. They can give a complete view of body organs. What is a CAT scan? CAT stands for a kind of machine. It is a special X-ray machine that gets a 360-degree picture of a small area of a patient's body. Doctors use X rays to study and determine diseases and injuries within the body, X rays can find a foreign object inside the body or take pictures of some inside organs to be X-rayed. A CAT scanner, however, uses a group of X rays to give a cross-sectional view of a specific part of the body. A fine group of X rays is scanned across the body and around the patient from many different directions. A computer studies the information from each direction and produces a clear cross-sectional picture on a screen. This picture is then photographed for later use. Several cross sections, taken one after another, can give clear "photos" of the entire body or of any body organs. The latest CAT scanners can even give clear pictures of active, moving organs, just as a fast-action camera can "stop the action", giving clear pictures of what appears unclear to the eye. And because of the 360-degree pictures, CAT scans show clear and complete views of organs in a manner that was once only shown during operation or examination of a dead patient. Frequent appearance before X rays can cause skin burns, cancer or other damage to the body. Yet CAT scans actually don't cause the patient to more radiation than regular X rays do. CAT scans can also be done without getting something harmful into the patient, so they are less risky than regular X rays. CAT scans provide exact, detailed information. They can quickly find such a thing as bleeding inside the brain. They are helping to save lives. We can infer from this passage that_.

"doctors need no opening-up of the body with CAT scanners",
