There are robots all around us,Some do very complicated jobs like flying airplanes and driving subway trains. And some do a simple job. When an automatic washing machine is switched on, water pours in. The machine waits until the water is hot before washing the clothes. It does this by "feedback". Information about what is happening is "feedback"into the robot to tell it what to do next. Our eyes,ears and other senses are our feedback. They tell us what is going on around us. So robots are like people in two ways:They work and they have feedback. There are robots all around, making our lives easier. Some of them, like the pocket calculator, can work much more quickly than human beings can. And they rarely make mistakes. In some ways robots are better than people. They work quickly, but do not make mistakes. They do not get bored doing the same job over andover again. And they never get tired. Robots are very useful in factories. They can be taught to do many different jobs. First their electronic brains must be shown how the job is done. A person moves the robot's"arm"and"hand"through each part of the job. The robot's brain remembers each move. When the robot is put to work on its own, its brain controls the rods, wheels and motors which move its arm. When the robot is needed for a new job, its electronic memory is"wiped clean."Then it is taught how to do its new task. If the robot's hand stops working, or if something gets in the way, it cannot do the next part of the job. So it stops and signals for help, then a human engineer repairs it. The most"intelligent"robots can move and see. Their eyes are cameras. Their metal fingers can feel shapes and even find out how hot and cold objects are. These robots have computer brains, linked to their eyes and fingers, which control their actions. In thisstory the author tells us that _ .

You may have noticed that you feel hungry a lot. This is natural----during teens, a person's body needs more nutrients to grow. Snacks are a great way to satisfy that hunger and get all the vitamins and nutrients your body needs. But you need to pay attention to what you eat. Filling your stomach with a lot of fries after class may give you a short-time help, but a snack high in fat and calories will only slow you down in the long time. To keep energy levels going---and avoid gain weight---keep away from foods like candy or soda. Look for foods like bread and grains and combine them with some food like peanut butter or low-fat milk or cheese. Choosing healthy snacks means shopping smart. Be careful of the health instructions on food bags. Here are some things to watch out for. That something is "all natural " doesn't necessarily mean that it's nutrients. For example, "all natural" juice drinks or sodas can be filled with sugar (which means they'll be high in calories and give you little nutrition.) A granola bar is a good example of a snack that people think is healthy. Although granola bars can be a good source of certain vitamins and nutrients, may also contain a great deal of fat, including a particularly harmful type of fat called trans fat. Check the Nutrition Facts instructions on the bag to be sure. We need snacks to _ .

On February 3, a Laysan albatross , a large seabird, named Wisdom, which is 62 years old, hatched a healthy chick on a Pacific island near Hawaii,. It was the sixth year in a row this bird has hatched a chick. Wisdom's species normally lives only 12 to 40 years, while she is able to hatch healthy chicks into her 60s. At breeding time, the Laysan albatross will dig out a shallow nest in the ground. The female then lays a single egg. Both she and her mate will take turns incubating the egg until it hatches. More than seven out of every 10 Laysan albatrosses' nests are on just one island -Midway Atoll. That's Wisdom's home. But her species spends most of its time in the air. In fact, biologists observe that after learning to fly, these birds may not set foot on land for the next three to five years. Albatrosses are powerful gliders , With their six-foot, nearly two-meter, wingspan, Laysan albatrosses can ride wind currents for hundreds of miles or more. Biologists now estimate that Wisdom has flown for an unusually large number of miles-between two million and three million. That is equivalent to traveling from Earth to the moon and back-four to six times! And in the months when these birds are not breeding, they stay in the air, and even sleep there. Wild albatrosses often die long before they come close to Wisdom's age. Some are eaten. Others starve, get sick or suffer life-threatening injuries from people's fishing boats. Clearly, Wisdom is special. She may have raised as many as 35 chicks in her life. Which of the following is TRUE about albatrosses?

[
"The females are responsible for hatching the eggs.",
"They can fly hundreds of miles or more in the wind.",

Maps of the world's population show that the majority of people today live near water. We live along coastlines, around bays, up the course of rivers and streams and on islands. We also vacation at the beach and find comfort fishing on a lake. Nothing makes small children happier than the chance of playing in water. More surprisingly, this human favor for water makes evolutionary sense. Sure, we need drinking water to live, but we have also benefited from what's swimming under the waves. Neuroscientist Crawford of the University of North London has proposed that our ancient ancestors attached to the sea, and that their devotion paid off by allowing the human species to develop large and complex brains. Crawford claims that when humans separated from apes and appeared in the forests of Africa, they stuck close to rivers and beaches and started catching fish, clams and crabs. That seafood was packed with omega-3 fatty acids, essential fatty acids that promote brain cell growth. It's no coincidence, Crawford claims, that human brain growth began to increase rapidly once we left the woods and headed for the beach. Scientists have also discovered that people who eat fish regularly are less likely to suffer from depression than those who eat less seafood. Biochemist Hibbelin of the National Institutes of Health has shown that across cultures there is a direct link between amount of fish eaten each week and rates of depression. More interestingly, Hibbelin and researcher Laura have found that fish is commonly used as a symbol of happiness and good health in various religions and cultures. We know that fish and the sea are good for us, and so we seek them out. We vacation on the coast and see the waves come and go, feeling happiness has taken over our brain. When we move inland, or go home from vacation, we lose touch with our sea roots and feel unhappy. To explain human's favor for water, the author _ .

The year 2006 was a busy one for space and technology workers. A planet lost its status and space flights caught the imagination of people around the world. The following is a short list of the major events of the year: _ IBM has built a chip that runs about 100 times faster than the ones we have now. The development could lead to faster computers. The chip was first made in June. It can run at a speed of 500 gigahertz . Pluto loses face The International Astronomical Union created the first scientific definition of the word "planet" in August. Under the new rules, Pluto is no longer called a planet but a "dwarf planet" . Pluto had been considered a planet since its discovery in 1930. For now, there are only the eight "classical" planets in the solar system : They are Mercury, Venus, Earth, Mars, Jupiter, Saturn, Uranus and Neptune. Woman space tourist The first woman space tourist was launched on a Russian rocket from Kazakhstan on September 18. The flight carried a businesswoman, named Anousheh Ansari, along with a fresh crew for the International Space Station (ISS). Ansari is a 40-year-old American. She has paid at least US$20 million for the trip. She returned on September 28 after her eight-day stay at the International Space Station. Discovery sent up The US space shuttle Discovery took seven astronauts on a 12-day repair mission to the International Space Station on December 9. It was the first night launch by NASA in four years. The last one ended in the failure of the space shuttle Columbia in 2003. The passage is written mainly to tell us _ .

Tears are nature's way of making us feel more comfortable. When our eyes is made uncomfortable by some small pieces of pollution, or when we are cutting onions, or when we are exhausted and "red-eyes" from over work and late hours, tears form in our eyes to clean and refresh them. Tears are also a sign of strong emotion . We cry when we are sad and we cry when we are happy. And tears seem to be uniquely human. We know that animals also experience emotion fear, pleasure, loneliness, but they do not shed tears. Biologically speaking, tears are actually drops of saline fluid, which is a little bit salty, produced by a gland in the body. Because salt is an important component, tears may actually constitute the most conclusive evidence that the human animal is the end product of a long evolutionary process that began in the sea. And it is clear that, in addition to the emotional benefits, the shedding of tears has a specific biological function as well. Through tears, we can eliminate from our body certain chemicals which build up in response to stress and create a chemical imbalance in the body. Crying actually makes us feel better by correcting that imbalance and making us feel good again. And thus the emotional and the biological functions of tears merge into one and make us even more "human" than we would otherwise be. Which of the following is the best title of the passage?

"Tears are a sign of strong emotion.",
"Tears are always making us feel more comfortable.",

Every five minutes my children ask me for the "latest thing". They tell me that all their friends have it already and they can't live without it. Our house is full of Game Boys, Play Station CDs and a million other "latest things". But, the one "latest things" we have refused to buy is a mobile phone. Our twelve-year-old son wants one, and we've said "no". He says he'll only use it for texting and he really needs it for emergencies. We don't want him to have a mobile phone, because it may be bad for children's health. Unfortunately, when I say, "As your father, I don't want you to have a mobile phone, because you might get a brain tumour ," he tells me that he doesn't mind. Why do twelve-year-old boys only want things that are bad for them? We've already told him that he can't listen to rap music--the words are disgusting . And I've said no to beer with his meals. Right now I'm saying no to everything. Then a few weeks ago he asked for something called a BB gun. He says everybody's got one. Of course they have. He shows me a website full of them and tells me it only fires plastic pellets . Finally, I say yes. I can't believe I've said no to phones and yes to guns. In October our son becomes a teenager, and I pray that research will find that mobile phones are safe...even better, that young people may become less moody--and more interested in personal hygiene . Until _ , I'm saying no. Which of the following is NOT the reason why the father said yes to a BB gun for his son?

In traditional Chinese medicine, the body, mind and spirit cannot be divided and so the unique whole-body treatment in Tui Na can also be a useful treatment correcting any imbalances in the body's energy before symptoms and disease can develop. It also works to bring back emotional peace as well as physical health. This is why after a Tui Na treatment many people "feel good". Many people in China use Tui Na regularly to keep healthy and to deal with some specific illnesses. Tui Na is performed on the clothed body and the patient is either lying on a couch or sitting on a chair. Therapists , by using a variety of movements, will control the intensity and direction of pressure in an exact way. The unique rolling movement in Tui Na is one of the most difficult movements to learn and students have to practice sometimes for many months on a rice bag before they are allowed to practice on the human body. Stress Tui Na is of course very useful for treating stress. It spreads the energy around the whole body. It is believed that Tui Na moves the strong energy in the tight muscles to the weaker areas, thus making a more balanced body. When your energy flowing inside your body is balanced, you feel relaxed and comfortable. Tui Na is especially useful for _ shoulders and tight neck muscles. Emotions In Traditional Chinese Medicine each major organ is linked to an emotion. By balancing the energy in the organ, the related emotion will be calmed. When your emotions are out of control, you would usually turn to your doctor or perhaps a psychotherapist . But perhaps some people would not like to be seeing a psychotherapist or feel nervous about discussing their problems with others. With Tui Na, one does not need to tell the therapist anything one does not want to. The treatment of Tui Na can deal with the problem itself. But if one does need to pour out his/her worries or troubles, an active dialogue between the psychotherapist and the patient will help to get a better effect. Organs & Emotions Each major organ -- the heart, the stomach, the liver , the lungs, and etc.--are linked to a relevant emotion. The heart is linked to joy, excitement and sadness. If the heart is out of balance, the patient may dream a lot at night and often forget something important in the day. The stomach is connected with too much thinking or worrying about anxiety. When the stomach is out of balance there is often a lack of energy. The patient often feels very tired and has no interest in doing anything at all. The liver is linked to anger. In Chinese medicine, the eyes are connected with the liver, and many people who suffer from anger often suffer from eye problems. The lung rules decision-making and too much energy here can lead to rashness , while if there is too little, it can bring about indecision. When there is a history of depression with a patient, it may have effect on the liver. ks5u Tui Na can help release most of the discomfort and it is used in almost all the hospitals in China and very popular among Chinese people. It is a useful and valuable method for the balance of your energy flowing, when emotional and physical health is out of balance. Tui Na is one of the remaining secrets of Chinese medicine. How can the emotion be calmed by Tui Na?

Scientists from the United States say they have found fish and other creatures living under key waters in Antarctica. They made the announcement after completing three months of research at the Ross Ice Shelf, the world's largest floating ice sheet. The researchers hoped to find clues to explain the force of the melting ice and its effect on sea level rise. Reed Scherer and Ross Powell are with Northern Illinois University in DeKalb, Illinois. They just finished up their research on our southernmost continent. Money for the project came from America's National Science Foundation. "We chose a study site where, in the first year ,We went into the subglacial lake and tried to understand the environment in there, both ecologically and in terms of the ice dynamics about how the lake operates ,and how the sediment underneath the ice sheet operates, as well, because it's the water and the sediment underneath the ice that controls how fast the ice is flowing into the ocean" says Ross Powell, who led the investigation. The team included scientists ,engineers, machinery and other supplies across the ice from the main U.S. scientific base at Mc Murdo Station to the researcher's camp .The camp was near a subglacial lake ,where an earlier study took place, Ross Powell says the latest study may provide evidence that can help predict the effect of climate change on rising sea levels. "What we have found is that these are very sensitive areas to the stability of how dynamic the ice is and how fast the ice may react to increases of melting both from the ocean and the atmosphere." Among the new instruments built for the project was a powerful hot water drill. The researchers used the drill to dig down some 740 meters. They collected water ,sediment and other material from the grounding zone. Working around the clock before the deep hole refroze, they sent a video camera down to the 400-square-meter undersea area. Reed Scherer says the video images they saw in the Command Center were a total surprise. "It's a very mobile environment. The bottom is changing constantly. And so the things that we saw were all very mobile organisms, things that swim and some things that crawl. And obviously they are getting enough nutrition that they can thrive, Some of the little crustacean-like creatures called amphipods that we saw swam quite quickly and were quite active." This is the farthest south that fish have ever been seen. How did the creatures get here? What do they feed on? And what effect will the retreating ice have on them? Ross Powell says the ice and sediment cores taken from the grounding zone can offer clues. "We know that the ice is melting there at the moment and so by opening up the cores once they get back, we hope to be able to understand what the ice was doing in the past ,relative to what it is doing now. And because it is melting so fast or seems to be melting fast at the moment, we anticipate that there will he some differences that we'll see in the history of the ice sheet from the sediment cores, once we open them up ."But Ross Powell says the work raises more questions than it answers. Scientists conducted the three-month research at the Ross Ice Shelf with the intention of _

One day, I went to see my last patient, an old woman. In the doorway, I saw she was struggling to put socks on her swollen feet in the bed. I stepped in, spoke quickly to the nurse, read her chart noting . I was almost in the clear that she was not in serious condition. I asked, "Could I help put on your socks? How are you feeling? Your sugars and blood pressure were high but they're better today. The nurse mentioned you're anxious to see your son. He's visiting you today. It's nice to have a family visit. I think you really look forward to seeing him." "Sit down, doctor. This is my story, not yours." She said with a serious voice. I was surprised as I helped her with the socks. She told me that her only son lived across from her house, but she had not seen him for five years. She believed that was the main cause of her health problems. After hearing her story and putting on her socks, I asked if there was anything else I could do for her. She shook her head no and smiled. All she wanted me to do was to listen. Each story is different. Some are detailed and others are simple. Some have a beginning, middle and end but others don't have clear ends. Some are true but others not. Yet all those things do not really matter. What matters to the storyteller is that the story is heard -- without interruption or judgment . It was that woman who taught me the importance of stopping, sitting down and truly listening. And, not long after, in an unexpected accident, I became a patient. 20 years later, I sit all the time -- in a wheelchair. For as long as I could, I continued to see patients from my chair. I believe in the power of listening. Which statement is NOT right according to the passage?

A 14-year-old British student is packing for the next day of school: textbooks, notebooks, pens, 250 grams of flour, an egg and some cooking oil. Wait, what? It's not a joke. From September, cookery will be a compulsory course for kids aged 7-14 in the UK. Primary school students will learn how to put things together and make simple, healthy food. At high school, students will then master a number of different meals. They will also learn some cooking skills including baking. Britain is sometimes known as a country with bad food and unhealthy eating habits. These new courses are part of the country's effort to bring healthy food back onto the table. "One in four British families no longer has a table that everyone can eat around. One out of every two meals we eat is eaten alone. Only four out of ten of us enjoy eating meals with our children," British writer Joanna Blythman wrote in her book Bad Food Britain: How A Nation Ruined Its Appetite in 2006. Instead, ready meals have become the first choice for many British kids, because their parents are often too busy to cook a proper meal. The Department for Education hopes that the cookery courses can introduce children to good food and reduce childhood _ . "It's important that children can develop an interest and understanding of good food," said a spokesman for the department. "We want to encourage them to develop a love of food and cooking that will stay with them as they grow up. From the passage, we can learn that _ .

When I arrived in Beijing more than five years ago, I had already given blood 79 times. I wanted to continue to be a donor and asked around if there was a Red Cross clinic in Beijing. There was one, and I went. I was very surprised to be received as a hero; for me, a blood donation was simply a good habit and a gift of love to Humanity. In Canada, donors can give 450ml each time every 51 days. That means six times a year. In China, we can give only 200ml, every four months. In 1984, there were only 19 donors in Beijing who offered their blood for free. One year later, there were 141. In 1986, 1,083, and so on until the figure reached 10,046 in 1990,14,016 in 1992 and more than double that the following year. There were 41,037 in 1994, and my statistics stop here. I'm so glad to see that the Chinese have understood that giving blood is not dangerous, and that it's a way to say, in a real communist spirit, "brother, I love you". In fact, every time I give blood, I think of my blood running in a man or a woman's veins, someone who has become my brother or my sister through a transfusion. Thirteen Chinese have become my s now; isn't that great? Giving blood is like giving birth. Some of these thirteen people may have died without my donation; doesn't that make it worth becoming a volunteer? What makes me even happier is when I can convince a Chinese friend to come with me and become a donor too. From the third passage we can infer that _ .

The time children spend outdoors could be linked to a reduced risk of being short-sighted, research suggests. An analysis of eight previous studies by University of Cambridge researchers found that for each additional hour spent outside per week, the risk of short-sightedness was reduced by 2%.They said exposure to natural light and time spent looking at distant objects could be key factors . The studies involved more than 10,000 children and adolescents. Dr Justin Sherwin and his research team concluded that short-sighted children spent an average of 3.7 fewer hours per week outdoors than those who either had normal vision or were far-sighted. But they said the reasons were not yet clear.They expected to find that children who spent more time outdoors also spent less time doing activities like reading, studying or playing computer games, but no such link was found in two of the eight studies which looked at this relationship. However, Dr Sherwin said they would now need more precise data to try to understand which factors, such as increased use of distance vision, reduced use of near vision, natural ultraviolet light exposure and physical activity,are most important. "Any increase in time spent outdoors must be weighed against exposure to ultraviolet radiation and the increased risk of skin cancer, cataracts and other cancers."he said."On the other hand, increasing outdoor physical activity could protect against diabetes and obesity, for example." Short-sightedness is a common eye condition that causes distant objects to appear blurred , while close objects can be seen clearly. It is much more common today in the UK and the United States than it was just 30 to 40 years ago. Approximately 1-2% of five-year-olds to seven-year-olds in the UK have short-sightedness.About.five million British people are short-sighted and some 200,000 of them will be seriously short-sighted. In some parts of Asia, more than 80% of the population suffers from short-sightedness. Which of the following is TRUE?
|
[
"Students who spent more time outdoors read less",
"Only one factor contributes to short-sightedness",
"The increase in time spent outdoors means more exposure to ultraviolet radiation",

We all know that exercise is good for your health. But some kinds of exercise may be better than others. Running, for example, may help to protect against heart disease and other health problems. Running may also help you live longer. Recently, researchers studied more than 55,000 adults. About a quarter of the adults have a good habit of running. The study found these runners were much healthier than non-runners. In fact, the runners lived, on average , three years longer than the non-runners. Running may be good exercise, but it can be difficult on the body. Here are commonly shared ideas among fitness experts to lower the risk of injury for people who are new to running. [?]Take it easy. Do not run too much, too soon or too fast. Most people get running injuries when they push themselves too hard. The body needs time to get used to increases in distance or speed. [?] Get good running shoes. There is no single best shoe for every runner. You should find the shoe that offers the best fit and support for your feet. More importantly, you should have a new pair of shoes every 500 to 800 kilometers. [?]Take good notes. Take time after each run to write down notes about what you did and how you felt. Look for things that happen again and again. For example, you may find that your knees hurt when you run sometimes. But perhaps you feel great when you have a rest between running days. These notes will help you make the best plan for running. Increases in distance or speed depend on _ .

A recent trend in Californian restaurants shows new eating habits among those people out to have an interesting dining experience. Appetizers seem to be the name of the games as diners turn away from the more traditional three-course meal in favor of smaller snacks served in various types of restaurants, bars and cafes. In this way, in the course of an evening out, you might go to a restaurant for a tasty dish to eat at one end of town, to a bar with some live music at the other end, then for a coffee, and finally back to the restaurant for a further appetizer. Reasons for this trend are the fact that so many different types of restaurants have been set up recently, each with their own particular type of food and special atmosphere, together with the increased specialty in the type of snacks being offered. Gone are the cheese sticks of the old days, when appetizers were not really taken seriously. Some favorite snacks of the moment are slices of hot pizza, creamy fish-based dishes and crispy cakes and so on. Prices for appetizers are not equal to a full meal; however, their new popularity has meant that they are by no means as cheap as they used to be. Certainly, for that special occasion, a meal in a nice restaurant, complete with the piano performance, is hard to beat. However, if we see this trend for "butterfly eating"---moving around several different places in one evening continues, then all the traditional style restaurants may well have to provide their own appetizer bars as well! If you go out for an evening of appetizers, you are likely to _ .

Wherever life takes you after A-level results day, it's likely to bring increased independence. That means it's time to take care of yourself. Students, take note. When you arrive at university, make sure you register with a doctor near your term-time address. If there is a university doctor at your institution, they will be your best choice. If not, ask student services for a recommendation. Once registered, do everything you can to make sure you never have to pay them a visit. Don't take unnecessary health risks. Cook meat thoroughly. Throw food away if it's out of date. Clean up after yourself. Food poisoning can be harmful, but it's easy to avoid if you pay due care and attention. University often brings a certain lifestyle, and while that's usually a whole lot of fun, it can quickly tip into a whole lot of sorrow. Know your limits when it comes to alcohol. Habitual drinking can be dangerous, and while every student will have nights of excess, these should be the exception, not the norm. Look out for your friends, too. If you're worried about alcohol or substance abuse, visit alcoholics-anonymous.org.ukorukna.orgfor free and confidential support. Anyone living with teenagers and young adults, especially in environments such as halls of residence, must accept that germs will be shared. Bugs and colds will spread like wildfire. Living communally brings certain health risks, and _ is probably the most serious of these. Symptoms include a rash, stiff neck and an aversion to bright lights. It's rare, but seek immediate medical attention if you're concerned (meningitis.org). Gappers, meanwhile, may need to consider specific health risks. If you're planning a trip abroad, especially in rural areas of poor countries, make sure you get the necessary vaccinations in good time before you leave. Research these at www.netdoctor.co.uk. You should be able to get everything you need from your doctor, although you may have to give them notice and you may have to pay, even on the NHS . If you also need to take medication while you're away, such as anti-malarials, do it faithfully. On a general note, whoever you are, wherever you are and whatever you do with your time, never walk alone at night, especially in quiet and badly lit areas. Always carry your phone. Never get in an unlicensed cab. Be careful who you trust. Respect your new independence, and keep yourself safe. Which of the following statements is true?

The way people hold to the belief that a fun-filled,pain-free life equals happiness actually reduces their chances of ever attaining real happiness.If fun and pleasure are equal to happiness then pain must be equal to unhappiness.But in fact,the opposite is true:more often than not things that lead to happiness involve some pain. As a result,many people avoid the very attempts that are the source of true happiness.They fear the pain inevitably brought by such things as marriage, raising children, professional achievement,religious commitment,self improvement. Ask a bachelor why he resists marriage even though he finds dating to be less and less satisfying.If he is honest he will tell you that he is afraid of making a commitment.For commitment is in fact quite painful.The single life is filled with fun,adventure,excitement.Marriage has such moments,but they are not its most distinguishing features. Couples with infant children are lucky to get a whole night's sleep or a three-day vacation.I don't know any parent who would choose the word fun to describe raising children.But couples who decide not to have children never know the joys of watching a child grow up or of playing with a grandchild. Understanding and accepting that true happiness has nothing to do with fun is one of the most liberating realizations.It liberates time:now we can devote more hours to activities that can genuinely increase our happiness.It liberates money:buying that new car or those fancy clothes that will do nothing to increase our happiness now seems pointless.And it liberates us from envy:we now understand that all those who are always having so much fun actually may not be happy at all.

Tattoos and body piercings have moved up on the trend list in recent years. Around Western schools lots of teens are sporting new holes and "flesh ink" . As with all other subjects, the Chinese will surely have to deal with this situation with respect to their children. To get a better view of what has happened in the West, 1et's sit down and hear what they say. Tiara from Indiana: I personally think body piercing is sickening. If there were supposed to be holes in your body,you would have been born with them. I do,however,think that ear piercing is not wrong. There is a difference between ear piercing and belly button piercing. Ear piercing is not nearly as dangerous. I would be sick if someone stuck a needle in my belly button. Lee from Illinois: Hi! I live in Illinois. I am 23. I have 12 tattoos and three piercings. I love my tattoos and consider myself an art collector. You would be surprised at who has given me the thumbs up on my art work. People on the street stop me to look at the tattoo on my leg. Most of them don't know what it is. They just think the work itself is great. Subotai from California: I'm not forbidden of self-expression,but when I see high school students getting these piercings, I really wonder. In some cases, the drive is deeper and darker than mere fashion. A friend of mine tried piercing her own tongue with a safety pin. It got infected and she had a tongue the size of a cow's. Jackson from Ohio: I don't think it is wrong, but when people do it all over the place like their face and everything--I think that's ridiculous. People who get the big "dragons that cover the whole body--I don't think that's necessary." When I see naked chicks on guys, I think, "You have no respect for women." We can conclude that _ .

Living abroad to study can certainly be an interesting experience but is that alone a good enough reason for spending years far away from home? To make the experience truly worthwhile, there has to be a goal behind the decision to study abroad. This may be a wish to perfect language skills in a foreign language environment, or a clever move in your career development. You must also consider the costs, not just of living and studying abroad, but of applying. Most universities now charge application fees for international students. If after considering these points you are sure that you want to apply to study abroad, your next step is to choose the right programme of studies. Research your choices and select carefully. You must do your homework well. Most universities have information online but you can also email and ask them to send you more details. You can find a lot of information on school ranking from education websites. But read carefully. Different universities emphasize different strengths. Don't just think about the university's reputation ; look for the most suitable for your goals. Next, you must deal with a large pile of paperwork. This involves filling in application form, preparing your school records, and getting reference letters. Reading the instructions and requirements of the universities carefully is of great importance. Sadly, many fine applicants get kicked out in the first round, simply because they don't follow the application procedure properly. Money is another important consideration. Some scholarships are provided by governments, others by schools and colleges. This information, again, can be found on the Internet. If you find a scholarship that is suitable for you, follow the application procedure carefully; the earlier you apply, the better your chance of getting it. A school ranking list tells you _ .

(Natural News)Many parents have tried to gave their children a head start on education with get-smart videos and enrichment activities as early as infancy, but free play is often sacrificed, so the American Academy of Pediatrics says that the best medicine for busy children is an increase in traditional "playtime". A number of studies suggest that unstructured play can help children become creative, discover their own interests, develop problem-solving abilities, and relate to others socially, according to a report prepared by two academy committees for release Monday at the group's annual meting. On the contrary, a lack of such playtime can create stress for both children and parents, and it can also cause obesity when children spend too much time sitting in front of educational videos. The report notes lack of playtime could even lead to depression in many children. The report thinks the lack of playtime lies in the fact that parents want to have super-smart children and safe places for children to play is decreasing. A balance between free playtime and educational activities should be struck, the report states. "In the current environment, where so many parents feel pressure to be super parents, I believe this message is an important one," said Dr. Kenneth Ginsburg, the report's lead author and a pediatrician at The Children's prefix = st1 /HospitalofPhiladelphia. Noted pediatrician, author, and presenter of cable TV's "What Every Baby Knows," Dr. T. Betty Brazelton agreed. "Children with structured activities" are missing the chance to dream, to make their own world work the way they want it. That to me is a very important part of childhood.

Sheep Challenge Evolution A species of sheep lives on the Scottish island of Hirta. Hirta has plenty of grass for the sheep to eat, and no natural predators of the sheep live on the island. Some sheep have dark wool, and some have light wool. The sheep with dark wool tend to be much larger and stronger than the sheep with light wool. However, researchers have found that in the last 20 years, the sheep with light wool have increased in number. Usually, strength and size help animals survive and breed.

Alfred Nobel, a Swedish - born chemist, who died in 1896, at one time believed that his invention of explosives could bring wars to an end, But later he found he was wrong. Nobel was born in Sweden in 1833. With only one year of formal schooling, he became a chemist and inventor by age of 16. He was also a _ , speaking English, Russian, German and French besides Swedish. He wrote poetry . He began his work with producing liquid nitroglycerin for use in mining and construction. He then discovered that liquid nitroglycerin could be dried. He called it dynamite, after the Greek word dynamis, meaning "power". Then he became rich. When he died, his estate was worth about 89 million. Nobel never married, and he left most of his estate to those who have been known as Nobel Prizes. The money is invested and the interest is given out as yearly prizes for persons who have done something special for mankind in the fields of physics, chemistry, physiology, medicine, literature, and peace. Prizes were first awarded in 1901. Over the years, many great people such as Albert Einstein in physics, Marie Curie in chemistry, Martin Luther King, Jr. for peace and Mo yan for literature got the awards. Alfred Nobel believed _ .

These days, I'm surprised at what my classmates have changed since school started. It's not just the new teachers, new buildings, or new rules. I also notice how people are dressing differently. Dressing is not just a choice to keep warm. It's also a healthy personal choice in so many ways. Dress rules: Many schools have dress rules. They tell students what to wear at school. The teachers don't hope to see their students wear unsuitable clothes in the classroom. _ : The way we dress shows the way we feel about ourselves. If we aren't confident or need lots of attention, we'll often dress in ways that help us get that attention. If you want to get attention in a healthy way, you don't need to dress in an interesting way to express your mind. Body image : If some kids look very bad or ugly, dressing properly can cover them. And it can also help them feel beautiful and comfortable among their friends. Being what you wear: Dressing is important. Dressing in a wrong way can make people mistake you.

It would be a totally dark world without your eyesight.However, there is a lot we can do to preserve our eyesight. Protect your eyes from the sun.Continuous exposure to the sun's UV rays can severely damage your eyes over time.The UV rays from the sun will result in brown spots in the eyes or some eye diseases, in order to prevent harmful UV rays.if you plan to be in the sun for extended periods of time, you need to wear protective eye wear. Practice disease prevention.Diabetes is among the few diseases that can cause blindness if left untreated, mistreated or undiagnosed.One of the best ways to prevent disease related blindness is to prevent or control your disease.For example, if you have diabetes it is highly recommended that you eat a healthy diet.check your blood sugar often and lake medicine if your blood sugar is above 150. Add vitamin A to your diet.This concept is usually taught during your younger years.Vitamin A is required for the production of rhodopsin which is an eye pigment highly sensitive to light that is used to see in poor lighting conditions.To get your healthy portion of vitamin A, you can go to your local grocery store and pick up carrots, broccoli and other cruciferous vegetables. Visit your eye doctor routinely.Visiting your eye doctor can keep you up to dale on your eye health.You should visit your eye doctor for an eye exam once every one to two years (more often if you wear glasses) to help you keep good eyesight.You are advised to see your eye doctor immediately if you experience eye diseases or symptoms like loss of eye vision, eye pain, redness and itching around the eyes because _ eye diseases can result in permanent eye damage or blindness.

It is not a good idea for children to have to work hard. Children should study in school as hard as they can. They should not have to do heavy work with their bodies. When parents or others force their children to work hard, the results are never good. Many may be very bad. If a farmer makes his son work like a man, he may easily learn to hate farming. Children sometimes do too much in gardens, in shops, or even in their own homes. They soon begin to hate such work with a force, because that can destroy their happiness. But there may be a worse loss, child's love for its parents. The feeling may become something different. When that happens, the old kind of love never returns. It is not a good idea for _ to have to work hard.

Man-made nighttime lights have appeared everywhere in industrialized countries over the last century.What people are now asking is whether exposure to lightened darkness can affect the brain. To find out,Tracy Bedrosian,a doctoral student in neuroscience at Ohio State University,placed hamsters into two environments.In one,they were exposed to 16 hours of daylight and eight hours of complete darkness each day.In the other,the animals experienced 16 hours of daylight,but at nighttime,a dim light was kept on,at about the intensity of a TV screen lighting a dark room. After eight weeks,the researchers tested the hamsters for behavior that would suggest they were depressed.For example,they looked to see whether the hamsters still engaged in activities they normally enjoy,such as drinking sugar water. In people,loss of enjoyment is a major symptom of depression. Hamsters in both groups were given a choice between drinking tap water or sugar water.The hamsters exposed to light at night drank similar amounts of tap and sugar water----they'd lost their preference for the sweet treat. These changes in behavior were associated with changes in a brain region known as the hippocampus .The hamsters exposed to night light had a reduced number of so-called dendritic spines on the surface of cells in this region.These spines are hair-like things that stick out,and that brain cells use to communicate with one another. The findings match up with studies on humans that have d the hippocampus to be involved in depression. A patient with major depression has a smaller hippocampus. The brain changes in the hamsters might arise from fluctuations in the production of the hormone melatonin . Melatonin signals to the body that it's nighttime,but a light at night dampens its production. The hormone has been shown to affect mood,and so a decrease in melatonin might prompt depression,Bedrosian says. If the same mechanism is at work in people,then "people might want to try to avoid falling asleep with their TVs on at night,or to try to minimize light exposure during the night," she adds. According to the passage, the more light one is exposed to at night, _ .

But ever look at what people spend their money on? I have s and friends deeply in debt, spending $ 12 for every $ 10 they earn instead of the $ 8 you know they should be spending.When I see them, they're proud of their new whatever."What do you think of my new truck?" asked one from the driver's seat."Do you like my new shoes?" asked another on high heels."Check out my new big screen." said a third while holding the remote in his living room.We've all heard people fishing for compliments on their new toys. Every one of them was proud of what they'd financed.They seem to have bought it for the purpose of being proud, of showing off, of keeping up with the Joneses."Look at my new ...?" is everybody's favorite phrase, even when the object in question isn't theirs at all and won't be new when they've finally paid for it, if they ever do.

If you have ever been left wondering why your emails are riddled with grammatical errors, or why you can never quite find the right phrase, it may be because you are typing with both hands. Our vocabulary becomes richer and our writing style becomes more fluent when we type using just one hand, scientists have found. "Typing can be too fluent or too fast, and _ can actually weaken the writing process," said Srdan Medimorec, the lead author of the study conducted at the department of psychology at the University of Waterloo, Canada. "It seems that what we write is a product of the interaction between our thoughts and the tools we use to express them." Using text-analysis software, researchers asked 103 university students to write essays under different conditions, using one hand to type and using both hands to type. The software was used to analyze elements of the essays, such as range of vocabulary, sentence complexity and the cohesion of the writing. Researchers found that participants' vocabulary became more advanced when they typed with one hand rather than two. The research team said that by slowing our writing down, typing one-handed allows more time for an internal word search, resulting in a larger variety of words. In contrast, fast typists might just write the first word that comes to mind. However, it is important not to slow typing down too much. Those who typed essays one-handed in the current study slowed down to about the speed of handwriting. This is the first study to show that changing people's typing can make their writing get better. The researchers suggested that the speed of writing could affect writing quality regardless of the tools used, whether they are computers, or pen and paper, although further research would be required to prove that idea. Which of the following statements is true according to the passage?

[
"The study was carried out in 103 universities.",

When women sit together to watch a movie on TV, at the same time they usually talk about a lot of subjects, including children, men, careers and what's happening in their lives. When groups of men and women watch a movie together, the men usually end up telling the women to shut up. Men can either talk or watch the screen---they can't do both---and they don't understand that women can. Besides , women think that the point of all getting together is to have a good time and develop relationships--not just to sit there like couch potatoes staring at the screen. During the ad breaks, a man often asks a woman to explain the plot(the story that is told in a novel or play or movie etc.) and tell him where the relationship between the characters is going. He is unable, unlike women, to read the small body language signals that show how the characters are feeling emotionally . Since women originally spent their days with the other women and children in the group, they developed the ability to communicate successfully because they want to keep relationships. For a woman, speech continues to have such a clear purpose: to build relationships and make friends. For men, to talk is to connect to the facts. Men see the telephone as a communication tool for sending facts and information to other people, but a woman sees it as a way of keeping relationship. A woman can spend two weeks on vacation with her girlfriend and, when she returns home, telephone the same girlfriend and talk for another two hours. There is no convincing evidence that social conditioning, the fact that girls' mothers talked them more, is the reason why girls talk more than boys. Psychiatrist Dr. Michael Lewis, author ofSocial Behaviour and Language Acquisition, conducted experiments that found mothers talked to and looked at baby girls more often than baby boys. Scientific evidence shows parents reply to the brain differences of their children. Since a girl's brain is better organized to send and receive speech, we talk to them more. As a result, mothers who try to talk to their sons are usually pointed to receive only short complaints in reply. After a vacation with her girlfriend, a woman would talk to her again on the phone for hours so as to _ .

The blue tits have been inspecting the nest-box again this year. The male is the house-hunter but the female will make the final choice. He lands at the hole and turns his head to expose his white cheeks as a signal to attract the female from where she has been feeding. Among many birds that nest in holes, the male has a light-coloured patch on its plumage which acts as signal for drawing the female's attention to a suitable nesting-place. Unlike the blue tit, the redstart may be only the male that strikingly coloured and the female is not beautiful. A few years ago I was lucky enough to spot a pair of redstarts in action in a Walsh wood. The male was leading an interested female to holes that he had previously checked out. He sat at the entrance of each hole and put his head on to show off his white forehead, or his head in to reveal his tail. If the female failed to react to his visual signals, the male sometimes sang for extra effect, while gliding towards her on spread wings and tail. Once the female accepts by following the male through the hole the displays stop, you must be at the right place at the right time to watch them. You can spot a pair of redstarts in a Walsh wood _ .

Zach drove over to Mary's place. She would be his wife soon. She was in China, visiting her parents. Her son Bradley hadn't gone with her. Bradley was a junior in high school. He neither liked nor disliked Zach, even though he had known Zach for three years. Zach was still trying to get along well with Bradley. When Zach arrived, he asked if Bradley wanted to drive his car. Bradley had a driver's license. Bradley said all right. Zach told him not to drive fast, but that he could drive anywhere he wanted. Bradley got on the road. Zach gave Bradley a few driving tips: Don't drive next to big trucks, because you never know when they might crush you. Don't drive behind trucks filled with things, because you never know when something in the truck will fly out and hit your car. On their way back, Zach suggested that they stop at the golf course. He wanted to show Bradley how to play golf. Bradley wasn't interested. He preferred his video games. But Bradley soon discovered that golf was fun! He hit a lot of balls. Zach told him that he was doing well. The next day Bradley, for the first time ever, called Zach. He had a few blisters on his hands. Zach said that usually happened. Then Bradley asked if Zach would come next Saturday so they could take a drive and hit golf balls again. Zach said, of course, and felt happy. Zach let Bradley drive his car because _ .

The scientific world continues to be amazed by the speed of the development of cloning. Some scientists now suggest that the cloning of humans could occur in the near future. Despite the benefits of cloning, however, certain ethical questions concerning the possible abuse of cloning have been raised. At the heart of these questions is the idea of humans influencing life in a way that could harm society, either morally or in a real physical sense. Some people object to cloning because it allows scientists to "act like God" in the handling of living organisms. The cloning of Dolly raised the debate over this practice to a whole new level. It has become obvious that the technology for cloning Dolly could also be used to clone humans. A person could choose to make two or ten or a hundred copies of himself or herself by the same techniques used with Dolly. An active debate about the morality of cloning humans arises. Some people see benefits from the practice, such as providing a way for parents to produce a new child to replace one dying of a fatal disease. Other people worry about humans taking into their own hands the future of the human race. At the beginning of the twenty-first century, many scientists say the controversy over the ethics of cloning humans is overstressed because of the unpredictability of cloning in general. While scientists have cloned animals such as sheep, mice, cows, pigs, and goats, fewer than 3 percent of all those cloning efforts have succeeded. The animal clones that have been produced often have health problems. Scientists believe the rapid reprogramming in cloning can introduce random errors into a clone's DNA. Those errors have altered individual genes in minor ways, and the genetic defects have led to the development of major medical problems. Some scientists say this should make human cloning out of the question, but others argue that cloning humans may actually be easier and safer than cloning animals. Whatever, I agree that further research in the field of cloning is needed. Some scientists think the debate over ethics of cloning humans is overstressed because _ .

Offering a powerful new tool against terrorism, researchers have found a way to detect lies in the liar's blushing face. The technique, described in the journal Nature, uses a thermal camera to detect the sudden shift of blood flow in the face. The system performed as a traditional polygraph , the scientists report. Pushed by technological advances and with fresh interest since Sept.11, the discovery is part of the development in the scientific study of detection. Although the lie remains a mysterious phenomenon, researchers in recent years have found a number of new methods that might take the place of the polygraph, from brain scans, to slight changes in eye movement, to sparks of electrical activity that signal a person has seen a victim or a crime scene before. The new finding says, when a person tells a lie, there is a sudden change of blood to the area around the eyes. Although the change is not ordinary visible, the blood warms the skin, causing bands of color1 to appear through a camera sensitive to heat. One advantage of the camera can provide answers quickly, and doesn't require a highly trained expert to operate it or explain its results. In theory, this new technology could be used anywhere large numbers of people need to be quickly screened. But some scientists say the technology would need to be improved before it is ready for use, for it is possible that there are other reactions that cause a sudden change in blood flow in the face and there is also the danger that people will learn to fool the machine, the same way they try to fool polygraph examiners by controlling their breathing or taking drugs to relax themselves. It is NOT true that this new technology _ .

Robots industry is developing so rapidly that there is no denying that we may one day find ourselves surrounded by robots. The humanoid (human like) robots with two legs such as Honda Motor Co. Ltd's ASIMO would likely have an easier time climbing up stairs inside homes than a robot that moves on wheels, developers say. But it will be some time before such devices make their way into people's homes. "They may look smart, but they are still quite stupid," Shimoyama said. "I don't think they will ever be as smart as humans." While safety is an obvious concern, robots also need to be sensitive to people's needs. Researchers at Fujitsu Frontech Ltd and Fujitsu Laboratories responsible for developing "Enon", a guide and patrol robot designed for use in shopping malls and corporate facilities , are working on this. Enon, which has a humanoid upper body but no legs, is equipped with a touch screen on its chest and space in its stomach to carry loads weighting up to 10 kg. In guide mode, it will check a newcomer and approach the person with a nod and a greeting: "Are you a visitor? Hello." Visitors requiring directions can point to icons displayed on Enon's chest screen. If the restroom icon is pressed, the screen will display a map that shows the way. The robot will then face and point in the direction of the restroom, although it won't actually walk the visitor there. Enon is now in use at four locations in Japan, including a shopping mall near Tokyo. The main goal is to make it more helpful for the elderly. "People who work in the transportation sector often ask whether we can build a robot that will find elderly people who look lost in train stations, and ask them if they are all right," said Toshihido Marita, director of Fujitsu Laboratories Ltd's autonomous system laboratory. "Actually that is hard to do, very hard," he said. The advantage of Honda Motor Co. Ltd's ASIMO is that _ .

There is just one four-legged animal that can walk two hundred miles without stopping once to rest. It would take a person two days and two nights to walk this far, and only one man has ever done it without stopping. What amazing animal has such endurance ? The camel! The camel is well known for something else, too. It can cross an entire desert without a single drink of water. Its body is built in a special way to help it store water and food. A person has just one stomach, but a camel has quite a few. Within each stomach are layers and layers of cells. These cells are like tiny water balloons, storing liquids until the camel needs them. When the camel drinks, the cells grow larger and larger. For a whole week, they can keep the animal's thirst away by sending water to all parts of its body. Have you ever wondered why the camel has a hump ? The hump is a storage place for fat. Because it has this storage area, the camel does not need to eat very often. When the animal needs energy, the layers of fat serve as fuel to keep it going on the long, hot days in the burning sun. The camel has another gift that makes it well suited to arid regions. This gift is its amazing nose. A camel can smell a water hole from miles away! When a camel moves, it sways from side to side like a ship on a wavy ocean. Because of this swaying motion, the camel has been called the "ship of the desert". Which factor contributes to a camels' endurance except _ ?

Most evenings, before watching late-night comedy or reading emails on his phone, Matt Nicoletti puts on a pair of orange-colored glasses that he bought for $8 on the Internet. "My girlfriend thinks I look ridiculous in them," he said. But Mr.Nicoletti, a 30-year-old consultant in Denver, insists that the glasses, which can block certain wavelengths of light emitted by electronic screens, make it easier to sleep. Studies have shown that such light, especially from the blue part of the spectrum , _ the body's production of melatonin ,which helps people fall asleep. Options are growing for blocking blue light, though experts caution that few have been adequately tested for effectiveness and the best solution remains avoiding brightly lit electronics at night. A Swiss study of 13 teenage boys, published in August inThe Journal of Adolescent Healthshowed that when the boys wore orange-colored glasses, also known as 'blue blockers' and shown to prevent melatonin, in the evening for a week, they felt "significantly more sleepy" than when they wore clear glasses.The boys looked at their screens, as teenagers tend to do, for at least a few hours on average before going to bed, and were monitored in the lab. Older adults may be less affected by blue light, experts say, but blue light remains a problem for most people, and an earlier study of 20 adults aged 18 to 68 found that those who wore orange-colored glasses for three hours before bed improved their sleep quality considerably relative to a control group that wore yellow-colored lenses, which blocked only ultraviolet light. LEDs used in devices such as smart phones, tablets and televisions tend to emit more blue light than incandescent products . LEDs are also increasingly popular as room lights, but "warm white" bulbs, with less blue, tend to be a better choice than "cool white" for nighttime use. The lighting company Philips also makes a reduced-blue LED bulb, meant to be used before bedtime."In theory, anything that will decrease that blue light exposure at night will be helpful." said Christopher Colwell, a scientist at the UCLA, "I know some gainers who swear by those orange-colored glasses." But orange glasses are not a panacea . Dr. Skene said."It isn't just getting rid of the blue and everything's fine," she said. The intensity of light, in addition to color, can affect sleep, she said, and not all brands of orange-colored glasses have undergone enough independent testing for their ability to aid sleep. During the daytime, experts say, exposure to blue light is good. Best of all is sunlight, which contains many different wavelengths of light."That's what our brain knows," said Kenneth P.Wright Jr., director of the sleep and chronobiology lab at the University of Colorado, Boulder. A 2013 study he led, published in the journalCurrent Biology, showed just how different things can be without nighttime lights. After participants had camped in the mountains for a week, their bodies began to prepare for sleep about two hours earlier than normal. Short of cutting out all evening electronics, experts say, it's advisable to use a small screen rather than a large one; dim the screen and keep it as far away from the eyes as possible; and reduce the amount of time spent reading the device. "If you can look at the iPhone for 10 minutes rather than three hours, that makes a lot of difference," Dr.Skene said. The purpose of this article is to _ .

The idea for a science experiment can come from an unusual place. After watching a YouTube video of a dancing bird named Snowball, a scientist in Californina decided to study the ability of animals to keep the beat. Bird lovers have long claimed that their pets have rhyhm, and there are many videos of dancing birds online. Until now, scientists have suspected that humans are the only animals that can accurately keep rhythm with music. Thanks to Snowball, is changing. Snowball is a cockatoo, a kind of parrot, and his favorite song is "Everybody" by the Backstreet Boys. When he hears the song, he moves his feet and rocks his body with the tempo, or pace of the music, as though he is the only bird member of the boy band. Aniruddh Patel is a neuroscientist, or a scientist who studies how the brain and the nervous system contribute to learning, seeing and other mental abilities. He works at the Neurosciences Instiute in San Diego. After seeing Snowbaill's dance online, Patel visited the cockatoo at the bird rescue facility he's called home for two years. The scientist played "Everybody" for Snowball and also played versions of the song that were sped up or slowed down. Sometimes, Snowball danced too fast or too slowly. Often, when there was a change in tempo, Snowball adjusted his dancing to match the rhythm. In other experiments, scientists have observed the same abilities in preschool children. Patel isn't the only scientist who has studied Snowball's moves. Adena Schachner, who studies psychology at Harvard University, also wanted to know more about the dancing bird. Schachner's team played different musical pieces for Snowball and a parrot named Alex, as well as eight human volunteers. The scientists observed that the birds and the humans kept time to the music with about the same accuracy. Schachner and her team watched thousands of YouTube videos of different animals moving to music. Not all the animals could dance, however. From watching the videos, the scientists observed that only animals that imitate sounds, including 14 parrot species and Asian elephants, accurately moved in time to music. The idea of studying animals' ability to keep the beat comes from _ .

Men have always believed that they are smarter than women. Now, a study has found that while this is certainly true, men also have to deal with the fact that they are also more stupid than the fairer sex. In the study, scientists measured the IQ of 2500 brothers and sisters and they found an uneven number of men not only in the top two percent, but also in the bottom two percent. The study's participants were tested on science, maths, English and mechanical abilities. Though there were twice as many men as women in the smartest group, there were also twice as many men among the bottom. The aggregate scores of men and women were similar. One of the study's authors, psychology professor Timothy Bates, said that the phenomenon may be because men have always been expected to be high achievers and women have been restricted to spend more time taking care of their homes. "The female developmental program may be tilted more towards ensuring survival and the safety of the middle ground.," the Daily Mail quoted Professor Bates, of Edinburgh University, as saying. The research _ past results that men were more likely than women to receive first class University degrees or thirds and women secured the seconds. It has been said that men are more ready to take risk when it comes to academics. Women have always found to be steadier in their learning. A past study has shown that women are securing more firsts and seconds, while men are continuing to receive more thirds. The argument for the change is that the increase of coursework at the cost of exams favors women's steady approach. According to Timothy Bates, less women are in the smartest group because _ .

Some people think only school children do not agree with their parents, however, it is not true. Communication is a problem for parents and children of all ages. If it's hard for you to communicate with your parents, don't worry about it. Here are some advice for you to _ the generation gap . Don't argue with your parents. Don't get to your parents when you are angry. Your parents probably won't consider your ideas if you are shouting at them. And you can't express yourself well if you are angry. Go someplace to cool off. Make sure you understand why you are unhappy. Then think about what you want to say to your parents. If you don't think you can speak to them at the moment, try writing a letter. Try to reach a compromise . Perhaps you and your parents disagree on something. You can keep your disagreement and try your best to accept each other. Michael's mother didn't agree with him about buying a motorbike. They argued over it. But they finally came to a compromise. Michael bought the motorbike, but only drove it on certain days. Of course, your parents might refuse to compromise on something. In these situations, it is especially important to show love and respect to them. Showing respect will keep your relationship strong. Talk about your values. The values of your parents are probably different from those of your own. Tell your parents what you care about, and why. Understanding your values might help them see your purposes in life. A good relationship with your parents can make you a better and happier person. It is worth having a try! ,. The best title for the passage is _ .

The Chang'e-3, named after a Chinese goddess, is China's first spacecraft to make a soft landing on the moon. It includes a lander and a moon rover called Yutu. The Chang'e-3 spacecraft is the second phase China's lunar rogramme, which includes orbiting, landing and returning to Earth. It follows the success of the Chang'e-1 and Chang'e-2 spacecraft in 2007 and 2010. The launch of Chang'e-3 was successful. The Chang'e-3 is one of the most difficult tasks in China's space programme, the news says. The news adds that exploring the universe and seeking peaceful use of space are dreams of Chinese for thousands of years. With a lander and the moon rover Yutu, Chang'e-3 soft-landed on the moon at 9:11 p.m. Saturday. Yutu later separated from the lander and ran to the moon surface earlier Sunday. China has chosen the name Yutu for its first moon rover, after a worldwide online vote attracted people to come up with names. In Chinese folk tale, Yutu is the white pet rabbit of Chang'e, the moon goddess. Chang'e took her pet and flew towards the moon. She became a goddess and has lived there with the white animal ever since. Which of the following is Not true?

Why doesn't the unemployment rate ever reach zero? Economists, who generally believe that supply tends to meet demand, have long thought about this question. Even in good times, i.e. not now, there are people who can't find work. And even in bad times, i.e. now, there are job openings. With over 14 million people out of work and looking for a job, you would think every available job would be filled. But that's not the case. Not now and not ever. On Monday, the Nobel Prize committee awarded the prize for economics to the three scholars who have done the most to explain this phenomenon. Two of the winners are Americans, Peter Diamond of MIT and Dale Mortensen of Northwestern. The third winner is Christopher Pissarides, who teaches at the London School of Economics and was born on Cyprus. Like most of economics, what they have found about why the jobless and ready-employers don't find each other seems obvious. You have to find out there is job opening you are interested in. Employers need to get resumes . It takes a while for both employers and employees to make the decision that this is what they want. And these guys came up with a frame-work to study the problem of why people stay unemployed longer than they should and what can be done about it. So what would today's Nobel Prize winners do to solve the current problem of the unemployed? And does the awarding of the prize contribute to the politicians' lowering joblessness? Speaking from his north London home, Pissarides told The Associated Press the announcement came as "a complete surprise" though his work had already helped shape thinking on both sides of the Atlantic. For example, the New Deal for Young People, a British government policy aimed at getting 18-24-year-olds back on the job market after long periods of unemployment, "is very much based on our work," he said. "One of the key things we found is that it is important to make sure that people do not stay unemployed too long so they don't lose their feel for the labor force," Pissarides told reporters in London. "The ways of dealing with this need not be expensive training - it could be as simple as providing work experience." According to Pissarides, _ is effrctive in dealing with unemployment.

The purpose of keeping fit is to avoid illness ,resist the mental and physical fatigue that make us more likely to contract infections ,and above all to feel more pleasure in being alive. Research has shown the value of a balanced diet ,fresh air, sunshine ,enough rest and some forms of regular exercise for everyone .If everyone followed this plan ,the number of people visiting the doctor and going to hospital would be considerably reduced. Unfortunately ,although most people acknowledge the importance of physical fitness ,not enough of us put this into practice .We spend too much time watching others from the comfort of an armchair or a seat in the stand at a sports stadium. One reason why people who are physically fit to live longer is that they do not put the heart under excessive strain and so they reduce the risk of heart and blood vessel diseases .They also avoid suffering the consequences of weakened muscles ,which are the cause of a great deal of back and abdominal trouble. About 640 muscles for about 45% of our body's weight ,they must have the ability to store energy and be continually supplied with fuel by the blood .Sensible exercise ,suited to each individual and preferably undertaken on the advice of a doctor ,is the best insurance of meeting these requirements. Which of the following is TRUE according to the passage?

How Do Animals Catch their ZZZ's ? Different creatures have developed some pretty creative ways to get their rest and stay safe. The lizard likes to sleep at the far end of small branches hanging out over a pond or lake in the rain forest. If a snake tries to slither up the branch to eat it, it will shake the branch and knock the lizard off, and the lizard will fall safely into the water. Chameleons can change color to match their surroundings in order to hide even while sleeping. Gorillas like to sleep high in the trees. They build a new bed every night, sometimes taking up to half an hour to pile branches, twigs, and leaves into a comfortable bed. Birds also find it safe to sleep in the trees, but unless they have eggs or young chicks, they don't use a nest. They just lock their feet around a branch and hang on. A special tendon in their legs is automatically tight when they are at rest, so they won't let go and fall. Dolphins live underwater, but must come to the surface to breathe. Scientists now believe that dolphins may sleep with only half their brain, while the other half stays awake to keep them safe and breathing. Seals also do this, lying on their sides on the surface of the water with one flipper underwater paddling to keep their noses above the surface. Some ducks may also have this ability, and actually sleep with one eye closed and one eye open. How does a chameleon protect itself while sleeping?

It's usually because the PC monitor in her refrigerator's door has informed her that a new email message has arrived. Rikke and her husband are taking part in a six-month trial sponsored by a Danish firm and two Swedish partners. They hope to show that computers can be put to much more practical daily use than most people think. Fifty families and singles were provided with a free model known as the "Screenfridge" for the duration of trial. "It's really very clever", says Rikke. She can call up email, news reports, sales items at the supermarket or addressed out of the endless ocean Internet possibilities. "I'm not the type who wants to sit in front of the computer and wait 10 minutes for the modem to connect," she says. The creators of the Screenfridge aim at this type of buyer. They think the machine should attract people who have limited time to solve technical problems or surf online. The PC that is built into the door is very small. It is only two centimeters wide, and completely silent. "Everything moves quickly", as Rikke admits. "Well, the whole thing is really just an amusement", she says. "But when the thing is gone after the test, it will be pain to have to go down in the basement again to download my email". The Screenfridge is due to hit the market sometime next year. How long has Rikke probably been using the Screenfridge?

What do you think of a " talking kitchen"? A French Digital Kitchen has been developed at Newcastle University in the UK. It teaches students how to cook French food and speak French at the same time. For the first time, students can learn a language by the following cooking steps. All grammar and _ have been carefully chosen to make sure the users can understand French well. After learning for some time, the users can test themselves by doing a short test on the computer. The kitchen project was started by Professor Paul Seedhouse. He became interested in the idea after he visited another kind of talking kitchen. He said, " The purpose of the French Digital Kitchen is to make learning a language more interesting and more educational." How does the kitchen work? There is a computer in the kitchen. With this computer, the users can first choose a French recipe( ) that they want to follow. Using information in the computer, the kitchen starts to guide the users how to make a French dish. If you follow the instructions on the computer, it moves on to the next. If you go wrong, the program goes back and repeats the recipe or information. At any time, the users can also ask the kitchen to repeat the recipe or any information.. The new kitchen can be used in school, universities and even people's homes. The researchers will also be developing the European Digital Kitchen, for the next three years. The passage is written to _

This was no ordinary class. The students who came together were all science or engineering professors at Cornell University. They had interrupted their research to accept an invitation to take part in an unusual experiment: "an interesting week of poetry." This class was part of a study to answer the questions: Why is science difficult for many nonscience students? What can teachers learn about teaching if they take a class that is not in their field? The students in the poetry class listened to lectures and took notes. They had reading tasks and had to write three short papers. All students noticed one thing - the importance of spoken words. In science and engineering classes, the instructors put tables and drawings on the blackboard. But in this poetry class, the instructors just talked. They didn't write anything on the board. The scientists and engineers noticed one similarity between science and poetry. In both subjects, students need to find layers of meaning . Some layers are simple, clean, and on the surface; other layers are deeper and more difficult. This search for different levels of meaning doesn't happen much in undergraduate science classes, but it is important later, in graduate school. And it is always important in humanities . Both the poetry instructors and their students learned something about teaching from this experience. One poetry instructor, for example, now sees the importance of using informative as he teaches. Most of the scientists agreed on several points. First, humanities classes might help science students to see patterns and decide which information is important. Second, the poetry class was fun. One engineer decided, "We need to change the way we teach engineering to make to make it an enjoyable experience for students." But perhaps the most important result of the experience was this; All of the professors began to think about how they teach and how they cam teach better. The experiment was designed to find out _

Too many people want others to be their friends,but they don't give friendship back.That is why some friendships don't last long.To have a friend,you must learn to be one.You must learn to treat your friend the way you want your friend to treat you.Learning to be a good friend means learning three rules:be honest;be generous;be understanding. Honesty is where a good friendship starts.Friends must be able to trust one another.If you do not tell the truth,people usually find out.If a friend finds out that you haven't been honest,you may lose the friend's trust.Good friends always count _ on one another to speak and act honestly. Generosity means sharing and sharing makes a friendship grow.You do not have to give your lunch money or your clothes.Naturally you will want to share your ideas and feelings.These can be very valuable to a friend.They tell your friend what is important to you.By sharing them,you help your friend know you better. Sooner or later everyone needs understanding and helping with a problem.Something may go wrong at school.Talking about the problem can make it easier to solve.Turning to a friend can be the first step in solving the problem.So to be a friend you must listen and understand.You must try to put yourself in your friend's place so you can understand the problem better. No two friendships are ever exactly alike.But all true friendships have three things in common.If you plan to keep your friends,you must practice honesty,generosity and understanding.

In recent years, advances in medical technology have made it possible for people to live longer than in the past. New medicines and machines are being developed every day to extend life. However, some people, including some doctors, are not in favor of these life extending measures, and they argue that people should have the right to die when they want. They say that the quality of life is as important as life itself and that people should not be forced to go on living when conditions of life have become unbearable . They saw that people should be allowed to die with dignity and to decide when they want to die. Others argue that life under any conditions is better than death and that the duty of doctors is always to extend life as long as possible. And so the battle goes on and on without a definite answer. Which of the following statements is true according to the passage?

(This selection was originally published in 1992. Pluto is no longer classified as a planet.) Pluto is in many ways the strangest of the planets. It is small and has a large moon(called Charon). Its orbit is unusual, which may cause it to have seasons in the sense that when it is close to the sun, the liquid methane on its surface boils to form a kind of atmospheric haze . When the planet moves farther away from the sun, it starts to snow solid methane. Pluto is not dark. Despite its great distance from the sun, the surface of Pluto is probably as bright as a moonlit night on Earth. The reason is all that methane, which is as white as newly fallen snow. The discovery of Pluto was more accident than design. The American astronomer Percival Lowell had predicted the existence of a ninth planet(he called it Planet X)based on what he took to be irregularities in the orbit of Neptune. Today astronomers argue that these "irregularities" weren't real, but the result of instrumental error. Nevertheless, Lowell produced predictions about where Planet X ought to be(although, to be honest, the predictions changed occasionally when he redid the calculations).In any case, in 1930 Clyde Tombaugh, doing a systemic sky survey that would have found the planet no matter where it was, discovered the planet we now call Pluto. By coincidence, its position was pretty close to where Lowell's last prediction said it should be. Was it just luck? We'll never know. On Pluto's surface, liquid methane boils to form an atmospheric haze, which would be most similar to _ .

Getting enough sleep on a regular basis is one important way to protect the health of your heart. Poor sleep is associated with a range of cardiovascular problems, including high blood pressure, heart attack, and heart failure. Both men and women are at increased risk for these conditions. But we continue to learn that when it comes to health problems associated with sleep, the particular risks to men and women are not always the same. A new study suggests that for women who already have heart disease, poor sleep may be particularly dangerous to their heart health. Research indicates that poor-quality sleep--and waking too early in particular--is associated with increased inflammation among women with heart disease. There was no similar association found for men, suggesting that women with heart disease and sleep problems may be at particular risk for inflammation that can be damaging to the heart. Researchers at the University of California, San Francisco investigated the relationship between sleep quality and inflammation linked to coronary heart disease. They also sought information about how an association between sleep and inflammation might differ between men and women. Their investigation included 980 men and women at first, and 626 completed the 5-year study. All of those included were suffering for coronary heart disease. The average age of men in the study was 66. Women were slightly younger, with an average age of 64. Researchers measured sleep quality by asking participants to rate their sleep over the previous month. They also asked for reports of some of the most common sleep problems, including difficulty falling asleep, difficulty staying asleep, waking frequently throughout the night, and waking too early in the morning. After 5 years, researchers repeated tests for inflammation and once again sought reports on sleep quality and sleep problems. When they analyzed data for both men and women together, researchers found no links between inflammations and sleep quality. However, when they analyzed data taking gender into account, researchers found a relationship between inflammation and sleep existed for women, but not for men. Which of the following is the suitable title for the passage?

There is one difference between the sexes on which every expert and study agrees: men are more aggressive than women. It shows up in 2-year-olds. It continues through school days and persists into adulthood. It is even constant across cultures. And there is little doubt that it is rooted in biology. If there's a woman's trait which is the same as men's aggressiveness, it's what social scientists refer to as the result of "education". Feminists have argued that the caring nature of women is not biological in origin, but rather has been forced into women by a society that wanted to keep them in the home. But the signs that it is at least partly inborn are too numerous to ignore. Just as tiny infant girls respond more readily to human faces, female toddlers learn much faster than males how to pick up nonverbal cues from others. And grown women are far more skilful than men at interpreting facial expressions: A recent study by University of Pennsylvania brain researcher Ruben Gur showed that they easily read emotions such as anger, sadness and fear. The only such emotion men could pick up was disgust. What difference do such differences make in the real world? Among other things, women appear to be somewhat less competitive--or at least competitive in different ways--than men. At the Harvard Law School, for instance, female students enter with qualities just as outstanding as those of their male peers. But they don' t qualify for the well-known Law Review in proper numbers, a fact some school officials owe to women' s discomfort in the incredibly competitive atmosphere. Students of management styles have found fewer differences than they expected between men and women who reach leadership positions, perhaps because many successful women deliberately imitate men. But an analysis by Purdue social psychologist Alice Eagly of 166 studies of leadership style did find one difference: Men tend to be more "autocratic"-making decisions on their own--while women tend to consult colleagues more often. Studies of behavior in small groups turn up even more differences. Men will typically dominate the discussion, says University of Toronto psychologist Kenneth Dion, spending more time talking and less time listening. Which of the following is true of women's nurturing nature according to the passage?

Whether it's for a hobby or profession, photography has always been highly valued. Photography has been around for over a hundred years, but what has recently revolutionized it is digital photography. A digital camera looks like a film camera, but it works differently. A digital camera takes pictures or a video by using a CCD sensor instead of film. The data about the images are electronically saved on a flash card. Later on, the flash card can be removed from the camera and put into a card reader. The card reader can be plugged into a computer's USB port. The images and videos can then be saved on a computer for viewing, editing, emailing, or printing. Digital photography received a great deal of criticism in its beginning stages, but with its continued development, it is now capable of producing images of a quality that is similar to. or even better, than that of film photographs. However, what really makes digital photography attractive is its convenience and low cost. Instead of having to go to a lab and waiting to get pictures developed to see what they look like, you can always view the images or-video on the LCD screen that is on the back of the camera. Not only does this feature save time, but it also prevents common mistakes like using a wrong exposure( ) that could ruin an image or video. With the usage of computer programs like Photoshop, more serious photographers can edit their images without the expense of a darkroom. Digital photography is also friendlier to the environment, as harmful chemicals that are needed in the development of film are not used in digital photography. Printing only the best pictures and not having to buy film make digital photography much cheaper. In a digital camera, an image is taken by the camera's _ .

Scientists are placing robotic dogs in the homes of lonely old people to test whether they can improve the quality of life for humans. Alan Beck, an expert in human-animal relationship, and Nancy Edwards, a professor of nursing, are leading the animal-assisted study on the effect of robotic dogs on old people's depression , physical activity, and life satisfaction. In the study, the robot, called AIBO, is placed for six weeks in the houses of some old people who live alone. Before placing AIBO in the home, scientists will collect baseline data for six weeks. These old people will keep a diary to note their feelings and activity before and after AIBO. Then, the scientists will review the data to test if it has produced any changes in the life of its owner. "I talk to him all the time, and he responds to my voice," says a seventy-year-old lady. "When I'm watching TV, he'll stay in my arms until he wants down. He has his own mind." The AIBOs respond to certain orders. The scientists say they have some advantages over live dogs, especially for old people. Often the elderly are disabled and cannot care for an animal by walking it or playing with it. A robotic dog _ exercise and feeding concerns. "At the beginning, it was believed that no one would relate(......) to the robotic dog, because it was metal and not furry." Beck says. "Hopefully, down the road, these robotic pets could become a more-valuable health helper. They will record their masters' blood pressure, oxygen levels or heart rhythms . AIBOs may even one day have games that can help stimulate older people's minds." In the research, the old people are asked to _ .

The extraordinary Eastgate Building in Harare, Zimbabwe's capital city, is said to be the only one in the world to use the same cooling and heating principles as the termite mound . Architect Mick Pearce used precisely the same strategy when designing the Eastgate Building, which has no air-conditioning and almost no heating. The building--the country's largest commercial and shopping complex--uses less than 10% of the energy of a conventional building of its size. The Eastgate's owners saved $3.5 million on a $36 million building because an air-conditioning equipment didn't have to be imported. The complex is actually two buildings linked by bridges across a shady, glass-roofed atrium open to the air. Fans suck fresh air in from the atrium, blow it upstairs through hollow spaces under the floors and from there into each office through baseboard vents . As _ rises and warms, it is drawn out via ceiling vents and finally exists through forty-eight brick chimneys. During summer's cool nights, big fans blow air through the building seven times an hour to cool the empty floors. By day, smaller fans blow two changes of air an hour through the building, to circulate the air which has been in contact with the cool floors. For winter days, there are small heaters in the vents. This is all possible only because Harare is 1600 feet above sea level, has cloudless skies, little dampness and rapid temperature changes--days as warm as 31degC commonly drop to 14degC at night. "You couldn't do this in New York, with its hot summers and cold winters," Pearce said. The engineering firm of Ove Arup&Partners monitors daily temperatures. It is found that the temperature of the building has generally stayed between 23degC and 25degC, with the exception of the annual hot period just before the summer rains in October and three days in November, when a doorkeeper accidentally switched off the fans at night. And the air is fresh--far more so than in air-conditioned buildings, where up to 30% of the air is recycled. Why was Eastgate cheaper to be built than a conventional building?

Until recently, the "science of the future" was supposed to be electronics and artificial intelligence. Today it seems more and more likely that the next great breakthroughs in technology will be brought through a combination of those two sciences with organic chemistry and genetic engineering. This combination is the science of biotechnology. Organic chemistry enables us to produce marvelous synthetic materials. However, it is still difficult to manufacture anything that has the capacity of wool to conserve heat and also to absorb moisture. Nothing that we have been able to produce so far comes anywhere near the combination of strength, lightness and flexibility that we find in the bodies of ordinary insects. Nevertheless, scientists in the laboratory have already succeeded in "growing" a material that has many of the characteristics of human skin. The next step may well be "biotech hearts and eyes" which can replace diseased organs in human beings. These will not be rejected by the body, as is the case with organs from humans. The application of biotechnology to energy production seems even more promising. In 1996 the famous science fiction writer, Arthur C. Clarke, many of whose previous predictions have come true, said that we may soon be able to develop remarkably cheap and renewable sources of energy. Some of these power sources will be biological. Clarke and others have warned us repeatedly that sooner or later we will have to give up our dependence on non-renewable power sources. Coal, oil and gas are indeed convenient. However, using them also means creating dangerously high levels of pollution. It will be impossible to meet the growing demand for energy without increasing that pollution to catastrophic levels unless we develop power sources that are both cheaper and cleaner. It is attempting to think that biotechnology or some other "science of the future" can solve our problems. Before we surrender to that temptation we should remember nuclear power. Only a few generations ago it seemed to promise limitless, cheap and safe energy. Today those promises lie buried in a concrete grave in a place called Chernobyl, in the Ukraine. Biotechnology is unlikely, however, to break its promises in quite the same or such a dangerous way. In 1996, Arthur C. Clarke predicted that _ .

Let's face it -- you're going to get a lot of well-intentioned advice from friends, parents and grandparents about your sleep. Some of this advice is going to be just wrong. Myth 1: Sleeping late on the weekends will make up for lost sleep during the week. Fact: Getting less than the amount of sleep that you need night after night accumulates over time and starts to create a "sleep debt". And like all debts, eventually you need to pay the price. The problem with waiting until the weekend to meet sleep needs is that in the meantime, you are paying the price of being less alert, feeling more moody, thinking slower and having less stimulation. Myth 2: A boring teacher (or warm room, full stomach, etc.) can put teens to sleep. Fact: If you are getting enough sleep on a regular basis, there is no teacher, math book or reading assignment in the world boring enough to make you fall asleep in class. There are basically two things that make people sleepy -- not getting enough sleep and not getting good quality sleep. The environment kids are in, including the room temperature, light level and entertainment value, may unmask underlying sleepiness, but the environment does not cause it! So if you are dozing off in class, don't blame it on bad teaching. Myth 3: Teenagers can pull an all-nighter to study and still be ready for the big test in the morning. Fact: Teenagers are much better off studying less and getting a good night's sleep. Research clearly shows that the ability to concentrate and learn new information, as well as to work efficiently, declines sharply after being awake for 15-16 hours, and continues to bottom out the longer you stay up. Plus, if the big test is at 8:00 am, the problem gets even worse. That's because morning time typically represents a low energy point in the body's normal 24-hour circadian rhythm, especially in teenagers. According to Myth 2, which of the following is TRUE?
|
[
"Students who eat a lot are sleepy at class.",
"The warm room can make students fall asleep easily.",
"Students' sleepiness has nothing to do with teaching.",
"The light level may lead students to feel sleepy ."
