We feel   28  and fall asleep at night and become  29  and energetic during the day. If the 24-hour cycle is   30  most people experience unpleasant   31 .

People from East Asia tend to have more difficulty than those from Europe in   42  facial expressions – and a new report published online in Current Biology explains why.
Rachael Jack, University of Glasgow researcher, said that rather than scanning evenly (均勻地) across a face as Westerners do, Easterners   43  their attention on the eyes.
“We show that Easterners and Westerners look at different face features to read facial expressions,” Jack said. “Westerners look at the eyes and the mouth in equal measure, whereas Easterners favor the eyes and   44  the mouth.”
According to Jack and her colleagues, the discovery shows that human   45  of emotion is more complex than previously believed. As a result, facial expressions that had been considered universally recognizable cannot be used to   46  convey emotion in a cross-cultural situation.
The researchers studied cultural differences in the   47  of facial expressions by recording the eye movements of 13 Western people and 13 East Asian people while they observed pictures of   48  faces and put them into categories: happy, sad, surprised, fearful, disgusted, angry, or neutral (中立的). They compared how accurately participants read those facial expressions using their particular eye movement strategies.
It turned out that Easterners focused much greater attention on the eyes and made   49   more errors than did Westerners. “The cultural difference in eye movements that they show is probably a reflection of cultural difference in facial expressions,” Jack said. “Our data suggest that whereas Westerners use the whole face to convey emotion, Easterners use the eyes more and mouth less.”
In short, the data show that facial expressions are not universal signals of human emotion. From here on,   50  how cultural factors have differed in these basic social skills will help our understanding of human emotion. Otherwise, when it comes to communicating emotions across cultures, Easterners and Westerners will find themselves lost in translation.

Energy is very important in modern life. People use energy to run machines, heat and cool their homes, cook, give light, and transport people and products from place to place. Most energy comes from fossil fuels—petroleum, coal, and natural gas. However, burning fuels causes pollution. Also, if we don’t find new kinds of energy, we will use up all the fossil fuels in the twenty-first century. Scientists are working hard to find other kinds of energy for the future. What might these sources of energy be?
Energy from the wind
All over the world, people use the power of the wind. It turns windmills and moves sailboats. It is a clean source of energy, and there is lots of it. Unfortunately, if the wind does not blow, there is no wind energy.
Energy from water
When water moves from a high place to a lower place, it makes energy. This energy is used to create electricity. In Brittany, France, for example, waterpower produces enough energy to light a town of 40,000people. Waterpower gives energy without pollution. However, people have to build dams to use this energy. Dams cost a lot of money, so water energy is expensive.
Energy from the earth
There is heat in rocks under the earth. Scientists use this heat to make geothermal energy. San Francisco gets half of the energy it needs from geothermal power. This kind of energy is cheap, but it is possible only in a few places in the world.
Energy from the sun
Solar panels on the roofs of houses can turn energy from the sun into electricity. These panels can create enough energy to heat an entire house. Solar power is clean and there is a lot of it in sunny places. But when the weather is bad, there is no sunlight for energy.
小題1:What does this passage mainly talk about?
A.Advantage of the energy from nature.
B.The future of the energy.
C.Scientists have been working hard to research other kinds of energy.
D.energy is the most important power in the word.
小題2:From the first paragraph we know ______.
A.energy can do everything for people
B.a(chǎn)ll the energy causes pollution
C.the new kinds of energy are badly needed
D.scientists have found other kinds of energy for the future
小題3:What is the writer’s opinion about the energy?
A.Try to use water energy more though it costs a lot.
B.Each natural energy has its own advantages and disadvantages.
C.Solar power is environmental.
D.Wind power is the cheapest but we can’t get.
小題4:What can be inferred from the passage?
A.In order to protect our environment, we should try other kinds of energy.
B.All scientists in the world will unite to find energy.
C.People in modern life use energy every day.
D.Energy changes people’s lives.

In the 1960s, medical researchers Thomas Holmes and Richard Rahe developed a checklist of stressful events. They appreciated the tricky point that any major change can be stressful. Bad events like “serious illness of a family member” were high on the list, but so were some helpful life changing events like marriage.
When you take the Holmes Rahe you must remember that the score does not show how you deal with stress -- it only shows how much you have to deal with. And we now know that the way you deal with these events dramatically affects your chances of staying healthy. By the early 1970s, hundreds of similar studies had followed Holmes and Rahe. And millions of Americans who work and live under stress worried over the reports. Somehow the research got boiled down to a memorable message. Women’s magazines ran titles like “Stress causes illness.”
If you want to stay physically and mentally healthy, the articles said, avoid stressful events. But such simplistic advice is impossible to follow. Even if stressful events are dangerous, many -- like the death of loved one--are impossible to avoid. Moreover, any warning to avoid all stressful events is a prescription for staying away from chances as well as trouble. Since any change can be stressful, a person who wanted to be completely free of stress would never marry, have a child, take a new job or move. The idea that all stress makes you sick also takes no notice of a lot of what we know about people. It supposes we're all vulnerable and not active in the face of the difficult situation. But what about human ability and creativity? Many come through periods of stress with more physical and mental strength than they had before. We also know that a long time without change or challenge can lead to boredom and physical and mental pressure.
小題1:.
The score of the Holmes Rahe test shows ____ .
A.how you can deal with life changing events
B.how helpful events can change your life
C.how stressful a major event can be
D.how much pressure you are under
小題2:.
. Which of the following expressions has the meaning most close to the underlined phrase “got boiled down to” in paragraph two ?
A.was argued aboutB.made clear
C.was concentrated onD.put an end to
小題3:.
. The studies on stress in the early 1970s led to ____ .
A.popular avoidance of stressful jobs
B.great fear over the mental disorder
C.a(chǎn) careful research into stress related illnesses
D.widespread worry about its harmful effects
小題4:.
Why is “such simplistic advice ”(Line 2, Para.3) impossible to follow?
A.No one can stay on the same job for long.
B.More effective ways have been found to get rid of stressful events.
C.People have to get married some day.
D.You could be missing chances as well.
小題5:.
. According to the passage people who have experienced ups and downs may become ____.
A.nervous when faced with difficulties
B.physically and mentally tired

If cars had wings,they could fly and that just might happen, beginning in 2011.The company Terrafugia, based in Woburn, Massachusetts, says it plans to deliver its car-plane, the Transition, to customers by the end of 2011.
“It’s the next ‘wow’ vehicle,”said Terrafugia vice president Richard Gersh .“Anybody can buy a Ferrari, but as we say, Ferraris don’t fly.”
The car plane has wings that unfold for flying—a process the company says takes one minute—and fold back up for driving. A runway is still required to take off and land.
The Transition is being marketed more as a plane that drives than a car that flies, although it is both. The company has been working with FAA to meet aircraft regulations, and with the National Highway Traffic Safety Administration to meet vehicle safety regulations.
The company is aiming to sell the Transition to private pilots as a more convenient and cheaper way to fly. They say it saves you the trouble from trying to find another mode of transportation to get to and from airports: You drive the car to the airport and then you’re good to go. When you land, you fold up the wings and hit the road. There are no expensive parking fees because you don’t have to store it at an airport—you park it in the garage at home.
The car-plane is designed to fly primarily under 10,000 feet. It has a maximum takeoff weight of 1,430 pounds, including fuel and passengers. Terrafugia says the Transition reduces the potential for an accident by allowing pilots to drive under bad weather instead of flying into marginal(臨界)conditions.
The Transition’s price tag: $194,000, But there may be additional charges for options like a radio, transponder or GPS. Another option is a full-plane parachute.
“If you get into a very awful situation, it is the necessary safety option,” Gersh said.
So far, the company has more than 70 orders with deposits.“We’re working very closely with them, but there are still some remaining steps,” Brown said.
小題1:
We can learn from the first paragraph that     .
A.car-planes will be popular in 2011
B.people might drive a car-plane in 2011
C.both Transition and Ferrari can take off and land
D.Richard Gersh is the vice president of Massachusetts
小題2:
lt takes the car-plane one minute to     .
A.fold and unfold its wingsB.unfold wings for flying
C.land in the airportD.meet flying safety regulations
小題3:
According to the passage, which of the following is NOT true?
A. The car-plane needs a runway to take off and land.
B. To meet aircraft regulations, the company has been working with FAA.
C. The car-plane may fly as high as normal planes.
D. People can park the car-plane in the garage at their home.
小題4:
The underlined word “it” in the last but one paragraph refers to     .
A.the radioB.the transponderC.the GPSD.the full-plane parachute
小題5:
What’s the best title for the passage?
A.Cars With Wings May Be Just Around The Corner
B.Which to Choose: A Ferrari or a Car Plane?
C.A more Convenient and Cheaper Way to Fly
D.Cars With Wings Can Fly as Fast as Planes

BERLIN — With the crisis in Japan raising fears about nuclear power, Germany and Switzerland said on Monday that they would reassess(再次評(píng)估) the safety of their own reactors([核] 反應(yīng)堆).
Doris Leuthard, the Swiss energy minister, said Switzerland would put off plans to build nuclear plants. She said no new ones would be permitted until experts had reviewed safety standards.
Germany will put off “the recently decided extension of the running time of German nuclear plants,” Chancellor Angela Merkel told reporters. “This moratorium(延緩)will run for three months and it will allow for a thorough examination of the safety standards of the county’s 17 nuclear power plants.
The European Union called for a meeting on Tuesday of nuclear safety authorities to assess Europe’s preparedness.
Germany’s foreign minister, Guido Westerwelle, called for a new risk analysis of the country’s nuclear plants, particularly regarding their cooling systems. He is the leader of the Free Democratic Party, which strongly supports nuclear power.
A previous government, led by the Social Democrats, passed a law in 2001 to close all the country’s nuclear plants by 2021. But Mrs. Merkel’s government changed that decision last year to extend the lives of the plants by an average of 12 years.
In Switzerland, Doris Leuthard said she had already asked to analyze the exact cause of the problems in Japan and draw up new or tougher safety standards “particularly in terms of seismic(地震的,與地震相關(guān)的) safety and cooling.”
In Russia, the Prime Minister said his government would “draw conclusions from what’s going on in Japan.”
小題1: Where can you most likely read this passage?
A.In a newspaper.B.In a magazine.C.In a science report.D.In a diary.
小題2:How will Germany react to Japan’s nuclear crisis?
A.Germany will close all the country’s nuclear plants.
B.Germany will hold a meeting of nuclear safety authorities.
C.Germany will change the decision made last year.
D.Germany will delay the extension of nuclear plants running time.
小題3:The author mentions all the following EXCEPT ______.
A.The moratorium in Germany will give time to examine the nuclear plants safety standards.
B.Switzerland will not build new nuclear plants unless they meet the experts’ safety standards.
C.The Social Democrats in Germany shares the same view with the Free Democratic Party.
D.Russia will try to learn something from the nuclear power crisis in Japan.
小題4:What is the best title of the passage?
A.Watch Out for the Danger of Nuclear Power
B.Europe Is against Building Nuclear Plants

Compared to people with bad attitudes,people who are cheerful and relaxed are less likely to suffer from colds,according to a new study.“It’s possible that being upbeat helps the body fight illnesses,” says Sheldon Cohen,the study’s lead researcher from Carnegie Mellon University (CMU) in Pittsburgh.
In a previous(先前的) study,Cohen and his colleagues put cold­causing viruses into the noses of 334 healthy adults. People who tended to be cheerful and lively were least likely to develop sniffles,coughs,and other cold symptoms. People who showed positive feelings were also less likely to mention symptoms to their doctors,even when medical tests detected those symptoms.
Those findings were interesting,but they didn’t prove that a person’s attitude affects whether he or she gets sick. Instead,it was still possible that a person’s underlying personality is what matters. Evidence suggests,for instance,that certain people are naturally more likely to be outgoing and optimistic,with high self­esteem and a sense of control over life. This would mean that who we are,not how we feel,ultimately decides our chances of catching colds.
To figure out which mattered more (personality or emotions),the CMU team interviewed 193 healthy adults. The researchers talked to each person over the phone every evening for 2 weeks. At the end of the interviewing period,people got nose drops that contained either cold or flu viruses. Then,each person stayed in an isolated room for 5 or 6 days. The results showed that everyone in the study was equally likely to get infected. Their symptoms,however,differed depending on the types of emotions that they had reported over the previous 2 weeks. Among those who reported good moods and had been infected with the flu virus,for example,28 percent developed coughs and stuffy noses. On the other hand,those symptoms struck 41 percent of people who had been less upbeat.
小題1:
What would be the best title for the passage?
A.Smiles Turn away Colds
B.An Interesting Way to Beat Colds
C.Be Outgoing and Optimistic to Fight Colds
D.What Matters More,Personality or Emotions?
小題2:
In the previous study,people who showed positive feelings______.
A.didn’t catch colds as often
B.developed cold symptoms more slowly
C.were less likely to have cold symptoms detected
D.were less likely to feel cold symptoms
小題3:
What mainly decides our chances of catching colds according to the new study?
A.Personality.B.Self­esteem(自尊).C.Emotions.D.Attitudes.
小題4:
The underlined word “symptoms” probably means________.
A.something that causes cold
B.something that results in cold
C.signs that something exists,especially something bad
D.changes in your body or mind that show that you are not healthy

The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong wish to go. A large part human history is connected with the exploration of the world in which we live. Again and again people have set out with surprising courage and patience to look into unknown regions and lands to see what had not yet been seen, to make known the unknown. With kites, balloons and aircraft they left the ground to pass through the lower atmosphere. Now the outer space receives their attention.
Why should man take the trouble of conquering space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say definitely just what the practical results will be is almost impossible.
小題1:
The main idea of the first paragraph is that __________.
A.man desires to explore what is unknown
B.man often goes wherever his dreams go
C.man is no longer interested in the study of the land and sea now
D.man’s history is the exploration of the world
小題2:
The word “manifold” in the second paragraph probably means __________.
A.vast B.various C.valuable D.practical
小題3:
The author seems to be in favor of__________.
A.doubting the necessity of the space exploration
B.the exploration of space
C.exploring more in space than in the sea
D.his experience in space
