Culture can affect not just language and customs, but also how people experience the world on surprisingly basic levels.
Researchers, with the help of brain scans, have ______ shocking differences in perception between Westerners and Asians, what they see when they look at a city street, for example, or even how they are _____ of a simple line in a square, according to findings published in a(n) _____ science journal.
In Western countries, culture makes people think of themselves as highly ______ entities. When looking at scenes, Westerners tend to focus more on central objects than on their surroundings. East Asian cultures, however, ________ inter-dependence, When Easterners look at a scene, they tend to focus on the surroundings as well as the object.
Using an experiment ________ two tasks, Dr. Hedden asked subjects to look at a line simply to estimate its length, a task that played to American’s _______. In another, they estimated the line’s length relative to the size of a square, an easier task for the Asian.
The level of brain activity, by ______ blood flow, was then measured by Brain Scanners. The experiment found that although there was no difference in performance, and the tasks were very easy, the levels of activity in the subjects’ brain were ______. For the Americans, areas ______ to attention were more favorable to them, when they worked on the task they tended to find more difficult --- estimating the line’s size relative to the square. The findings are a ______ of more than ten years of previous experimental research into East-West differences.
In one study, for instance researchers ______ people a choice among five pens; four red and one green. Easterners were more likely to choose a red pen, and Westerners were more likely to choose the green one.
Culture does not only make a(n) ______ on how you see the world, but how you choose to understand and internalize it. But such habits can be changed. Some psychological studies suggest that when an Easterner goes to the West or vice versa, habits of thought and perception also begin to change. Such research gives us ______ to how our brain works and holds new promises for us to develop programs to improve our memory techniques and __________ our learning skills.

For centuries, magicians have used various ways to shock the audience. We all have seen how a 36 performer carefully steps 37 a bed of burning coals -- barefoot. Then he walks across 38 a single burn on his feet. Is it mind over matter, or is it just physics? As it turns __39 , walking on burning coals isn’t that hot as 40 . “The coals are hot enough to 41__ you, but if you walk quickly across them you 42 being burned.” says Jonathan Hall, a physician at Penn State University in Eric Pennsylvania.
That’s because some coals are made 43 burning wood chips. Wood has two 44__ properties（特性）for fire-walking, explains Hall. First, wood is an insulator（绝缘体）--it doesn’t __45 heat very well. “It 46 _ time for heat to travel 47 the wood to your feet.” Hall says. If the performer walked across red-hot metal 48 , that would truly be 49 , because metal conducts, or transmits, heat very well. The metal would 50 burn a performer’s feet.
Second, wood has a low specific heat-- it doesn’t take much heat to 51 its temperature. Heat is a form of 52 . Temperature is a 53 of heat, in units of degrees. So 54 the coals are hot, the value（数值）of heat energy they contain is low. Thus, a well-trained performer can 55 such an amazing result.
Still, you don’t want to walk on burning coals, do you?

People often fall ill because of me. 36 , they can hardly blame me; it is largely their own 37 . A tired person may get 38 , especially when he goes to crowded places with polluted air. A sudden change in 39 is another factor. In hot summer, people turn on the air-conditioner upon returning home. They will catch a cold easily.
My latest victim is an energetic student. After school, he played football hard for two hours. Though 40 , he still went to the cinema .Then he got back home and took a cold shower immediately.
I seized this golden chance to 41 him .He reacted, trying to 42 me , but I was already 43 deep in his throat. He kept sneezing（打喷嚏） and his nose was running. 44 he put on some warm clothes, it didn’t work, for there were too many of us. Besides, his sore throat kept 45 him, and he developed a cough to force me and my family out, but 46 .
The next day he couldn’t go to 47 . He had lost his appetite and was not as 48 as before. His mother made him orange juice every few hours for more vitamin C, which would help his 49
For two days he was 50 by his mother. As he rested more, his defense strengthened and I began to feel the 51 . I knew I had to 52 him before long.

Sea turtles have been on Earth for millions of years, but they may soon die out. The main 1 to them is people who kill them for food, according to Dr. Wallace J. Nichols of the University of California.
But the latest news may 2 turtle hunting: Dr. Nichols has found that sea turtles 3 a lot of pollution from the ocean. This pollution is unhealthy for both turtles and humans. It can cause __4__ damage to their bodies and lead to death. Research shows that many people get sick and even die from eating sea turtle meat.
In the US, most people have never eaten turtle. This is because turtles are 5 by the United States law, which makes it 6 to harm or kill these amazing animals. “But many people in other countries still eat them,” explains Nichols. “Our first 7 was to save turtles; now we must save 8 too.”
Davis said he also wants to send out a bigger 9 that we should protect the oceans. “The health of the ocean, animals in the ocean, and our own health are all 10 . A clean ocean is really good for us too because of the food we eat from there.”

Almost everyone wants to get smarter. We struggle to improve our 36_ , intelligence and attention. We drink cup after cup of coffee to help us 37_ the day.
38 __, a new study published in Current Directions in Psychological Science warns that there are 39___ to how smart humans can get.
Each of our body parts develops in a certain way for a reason. 40 _, we are not 3 meters tall 41 _ most people’s hearts are not strong enough to send 42 _ up that high. Scientists say that our thinking ability works in the same way. A baby’s brain size is limited by a series of __43 , such as the size of the mother’s pelvis (骨盆). If our brains developed to be bigger, there could be more 44 during childbirth.
The study of Jews, who have an average IQ much _ 45_ than other Europeans, showed they were more _46_ to develop diseases of the _47_ system. This might be because of their increased brainpower.
If intelligence cannot be improved, can we at least get better at _ 48 _ ? Not really, say scientists. They studied _49_ like caffeine (咖啡因)that improve attention. They found the drugs only helped people with serious 50 _ problems. For those who did not have trouble paying attention, the drugs could have the 51 _ effect. Scientists say that this suggests there is a(n) 52 limit to how much people can or should concentrate.
Our memory is also a “double-edged sword”. People with extremely good memories could 53__ having a difficult life because they cannot _54 bad things that happen to them.
Thomas Hills, one of the authors of the paper, said that 55 all the problems in trying to get smarter, it’s unlikely that there will ever be a “super mind”.

Water and its importance to human life were the centre of the world’s attention last week. March 22 was World Water Day and 36 the theme “Water for Life”.
There are more than one billion people in the world who live without 37 drinking water. The United Nations 38 to cut this number in half by 2015.
Solving such a big problem seems like a(n) 39 challenge. But everyone, 40 teenagers, can do something to help. A teenage girl in the US has set an example to the 41 of her age around the world.
Rene Haggerty, 13, was awarded the 2004 Gloria Barron Prize for her work— 42 discarded(废弃的) batteries（电池）which pollute water.
In 2003, Haggerty went on a field trip to the Great Lakes Science Centre in Ohio. There she saw an exhibit about how 43 in old batteries harm the water of Lake Erie.
Haggerty learnt that 44 the batteries was an easy solution. “I think everybody can do it, because everyone 45 batteries, and it can make a big difference.” With these words, she began to 46 awareness in her area.
She 47 her county government and school board. She got permission to start a recycling programme in schools 48 the public library, hospital, and churches. With help from her family, friends and local waste-management 49 , she gathered containers, arranged transportation, and made a(n) 50 video.
Over the past two years, she collected four tons of batteries and drew the attention of officials, who were in charge of a battery recycling programme but had made 51 progress.
When asked 52 she feels like a hero, Haggerty is quite ____53 . “Not really. Well, maybe for the fish I saved!”
Every year the Gloria Barron Prize 54 young Americans aged 8 to 18 who have shown leadership and courage in 55 the public and the planet. Each year ten winners receive US $ 2,000 each, to help with their education costs or their public service work.

People do not analyse every problem they meet. Sometimes they try to remember a solution from the last time they had a 36 problem. They often accept the opinion or ideas of other people. Other times they begin to act without 37 ; they try to find a solution by trial and error. However, when all of these methods 38 , the person with a problem has to start analysing. There are six 39 in analysing a problem.
40 , the person must recognize that there is a problem. For example, Sam’s bicycle is broken, and he cannot ride it to class as he usually does. Sam must 41 that there is a problem with his bicycle.
Next the person must 42 the problem. Before Sam can repair his bicycle, he must know why it does not work. For example, he must 43 the parts that are wrong.
Now the person must look for 44 that will make the problem clearer and lead to 45 solutions. For example, suppose Sam 46 that his bike does not work because there is something wrong with the brakes. 47 , he can look in his bicycle repair book and read about brakes, talk to his friends at the bike shop, or look at his brakes carefully.
After 48 the problem, the person should have several suggestions for a possible solution. Take Sam as an example 49, his suggestions might be: tighten or loosen the brakes; buy new brakes and change the old ones.
In the end, one 50 seems to be the solution to the problem. Sometimes the 51 idea comes quite 52 because the thinker suddenly sees something in a 53 way. Sam, for example, suddenly sees there is a piece of chewing gum stuck to a brake. He immediately hits on the solution to his problem: he must 54 the brake.
Finally the solution is 55 . Sam does it and finds his bicycle works perfectly. In short he has solved the problem.

Adults are often surprised by how well they remember something they learned as children but have never practised in the meantime. A man who has not had an opportunity to go swimming for years can 1 swim as well as ever when he gets back in the water. He can get on a bicycle after several decades and still 2 away. A mother who has not 3 the words for years can teach her daughter the poem that begins "Twinkle, twinkle, little star" or recite the story of Cinderella or Snow White.
One explanation is the law of over learning, which can be stated as following: 4 we have learned something, additional learning increases the 5 of time we will remember it.
In childhood, we usually continue to practise such skills as swimming, bicycle riding long after we have learned them. We continue to listen to and 6 ourselves of poems such as "Twinkle, twinkle, little star" and childhood tales such as Cinderella or Snow White. We not only learn but __7 .
The law of over learning explains why cramming (突击学习) for an examination, 8 it may result in a passing grade, is not a 9 way to learn a school course. By cramming, a student may learn the subject well enough to get by on the examination, but he is likely soon to forget almost everything he learned. A little over learning, 10 , is usually a good investment toward the future.

One of the most remarkable things about the human mind is our ability to imagine the future. In our 16 we can see what has not yet happened．For example, while we are looking forward to visiting a new place or country, we 17 what it will be like. We predict the 18 people will eat, dress and act. Of course, we do not always predict things correctly. Things are often very different from the way we 19 them to be.
One of the 20 dreams in history is the dream of the German scientist, Kekule, who had been 21 to work out a very difficult problem in physics. He had 22 and analyzed the problem from every angle for days, but there seemed to be no way of 23 out the answer. Then one night he went to bed and dreamed．When he 24 up, he realized that he knew the answer. He had solved the problem in his 25 .
The hypnotist(催眠者) sat in the chair opposite him and spoke 26 : I want you to concentrate on my voice. Think about nothing. You know nothing but my voice. And as you pay attention to my voice, your 27 will get heavier. Soon you’ll be asleep.
You will hear my voice and 28 my words, but your body will be asleep, your eyes are too heavy. You are almost asleep, and when you wake up you will 29 nothing.

The massive magnitude（震级） 8.8 earthquake that struck the west coast of Chile moved the entire city of Concepcion at least 10 feet to the west, and moved other parts of South America as far apart as the Falkland Islands and Fortaleza, Brazil.
These measurements, produced from data gathered by researchers from four universities and several agencies, paint a much clearer picture of the power behind this earthquake, believed to be the fifth-most-powerful since instruments have been available to measure earthquake.
Buenos Aires, the capital of Argentina moved about 1 inch to the west. And Chile's capital, Santiago, moved about 11 inches to the west-southwest. The cities of Valparaiso and Mendoza, Argentina, northeast of Concepcion, also moved.
The quake's epicenter (震中) was in a region of South America that's part of the so-called “ring of fire,” an area of major seismic（地震的） stresses which encircles（环绕，包围） the Pacific Ocean. All along this line, the plates on which the continents move press against each other.
Mike Bevis, professor of earth sciences at Ohio State, has led a project since 1993 that has been measuring crustal（地壳的）movement in the Central and Southern Andes. The effort is called the Central and Southern Andes GPS Project, or CAP.
Ben Brooks, an associate researcher with the School of Ocean and Earth Science and Technology at the University of Hawaii, said that the event, offers a unique opportunity to better understand the seismic processes that control earthquakes.
“We now have modern, precise instruments to evaluate this event, and because the site borders a continent, we will be able to get evidences of the changes it caused.” said Brooks.
What is the main idea of the passage?
A．The earthquake in Chile was dangerous. B．Earthquake often happen in Chile C．The earthquake in Chile moved cities. D．The earthquake in Chile had been predicted.
A．Concepcion B．Buenos Aires C．Santiago D．Valparaiso
A．the fire and the earthquake B．the beautiful places around the ocean C．the plate on which South America lies D．the area around the Pacific Ocean
A．It is under the leadership of Mike Bevis. B．It observes earthquakes worldwide. C．It is designed to watch climate changes. D．It mainly studies the Pacific Ocean.

Most people think of birds as feathered animals that fly. Scientists, 36 , do not define (给…下定义) birds as animals that fly, because some birds do not. Of the 10,000 or so species of birds, 46 cannot 37 . Flight plays a key role in 38 for most birds. It allows them to find food over a 39 area and to get away from enemies. Ancestors of flightless birds may have 40 their ability to fly because they had no regular predators (捕食者) or did not need to fly to find food. Rather than fly, some of these birds developed other 41 to catch food and avoid enemies. Two examples of 42 birds are penguins and ostriches.
43 birds that fly, penguins do not have wide wings or large feathers. In order to catch the fish they feed on, penguins use their powerful wings to swim 44 . And when they swim, they look as if they are flying through the water. The 45 of penguins’ bodies makes it possible for them to dive deep underwater, 46 their thick feathers protect them from the cold.
Ostriches are known for their long legs, long necks, and large size. To 47 themselves, they stay in groups and use their excellent sight and hearing to 48 enemies. As soon as 49 approaches, they can run at a speed of more than 65 kilometers per hour to 50 . In addition to using their strong legs to run, they can kick powerfully.
Not all flightless birds have been 51 in protecting themselves. Flightless birds on some islands had no enemies until people 52 . These birds were hunted and easily caught by people and the animals 53 by people. Human land development has 54 the habitats of some birds.
