From childhood to old age, we all use language as a means of broadening our knowledge of ourselves and the world about us.When humans first 1 , they were like newborn children, unable to use this 2 tool.Yet once language developed, the possibilities for human kind?s future 3 and cultural growth increased.
  Many linguists believe that evolution is 4 for our ability to produce and use language.They 5 that our highly evolved brain provides us 6 an innate language ability not found in lower 7 . Proponents of this innateness theory say that our 8 for language is inborn, but that language itself develops gradually, 9 a function of the growth of the brain during childhood.Therefore there are critical 10 times for language development.
Current 11 of innateness theory are mixed, however, evidence supporting the existence of some innate abilities is undeniable. 12 , more and more schools are discovering that foreign languages are best taught in 13 grades.Young children often can learn several languages by being 14 to them, while adults have a much harder time learning another language once the 15 of their first language have become firmly fixed.
16 some aspects of language are undeniably innate, language does not develop automatically in a vacuum.Children who have been 17 from other human beings do not possess language.This demonstrates that 18 with other human beings isnecessary for proper language development.Some linguists believe that this is even more basic to human language 19 than any innate capacities.These theorists view language as imitative, learned behavior. 20 , children learn language from their parents by imitating them.Parents gradually shape their child's language skills by positively reinforcing precise imitations and negatively reinforcing imprecise ones.

Computers. Love them or hate them, it is impossible to escape from them in the modern age. They are so much a part of our everyday lives—from instant messaging to e-mails. With many people preferring to use e-mail rather than traditional regular mail, it has become very important to be aware of how we express ourselves when using e-mail. The requirement of etiquette(網(wǎng)絡(luò)禮儀)is obviously needed.
Grammar and spelling
Firstly, if you are dealing with a formal e-mail, pay close attention to grammar and spelling. Don’t forget to run your spell-check (program) at the end of the document, but don’t treat it as the final word. Carefully re-read it yourself, as sometimes even spell and grammar checking programs come up with some strange explanations. Remember, your first e-mail to a potential employer or college could be your last — you won’t want to spoil your first impression by making basic errors.
E-mail addresses
Also, for official e-mails, carefully consider your existing e-mail address. A funny e-mail address (such as pinkfluffycutiepie@…com) may be fine for using with your friends, but what impression do you think this address might give to an employer or college admissions officer? Consider using one address for personal e-mails and a different one for formal use.
Upper case(大寫字母)
Take care also NOT TO TYPE UNNECESSARILY IN UPPER CASE, as this is the e-mail version of shouting.
Personal information
You should beware too about giving away too much personal information over the Internet. It may feel much more comfortable to “talk” using instant messages as there are no uncomfortable silences or awkward moments, but never forget that—unless the person you are speaking to is a friend or family member—you really know nothing about them, so be careful. Further to this, NEVER agree to meet a stranger that you have spoken to online, as it can be extremely dangerous.
My final message though is—have fun! The Internet is exciting, useful and informative. But, as with so many things that we believe we can’t live without, it is a much better servant than a master.
60.The text is mainly about______.
A.how to express ourselves when using e-mail
B.computers, so much a part of our everyday lives
C.the Internet, a much better servant than a master
D.paying close attention to grammar and spelling when dealing with a formal e-mail
61.What does the underlined word “beware” mean?
A.think          B.be careful          C.care     D.know
62.If you use all capital letters, it looks like you are______.
A.yelling             B.careful             C.unprofessional       D.childish
63.Which of the following statements would the writer agree to?
A.As time goes by, many people prefer to use traditional regular mail again.
B.It’s fun to meet a stranger that you have spoken to online.
C.If you want to apply for a job, you can’t use a funny e-mail address when writing e-mails..
D.Grammar and spelling are not important when you write e-mails.

These days we hear a lot about how air pollution is changing temperatures on the earth. New evidence from a mountaintop in China now suggests that pollution can also change the amount of rain and snow that falls in some places.
Usually, more rain falls in mountainous places than in flat areas upwind from the mountains. That’s because air can hold a lot of water. When wind blows wet air up a mountainside, the air gets colder. This temperature change often forces water to fall as rain or snow.
In recent years, however, many mountainous areas in the western United States have been getting less rain than normal. Mountains that are downwind from cities have experienced the biggest drops.
Some scientists have theorized(推理)that pollution drifts (趨勢)from the cities into the mountains, affecting rainfall, but proving this link has been difficult.
Searching for answers, a team led by a scientist from the Hebrew University went to s mountain in China called Mount Hua, which is 2,060 meters tall and lies about 120 kilometers east of the Chinese city Xi’an. Since 1954, scientists have been collecting details about rainfall, humidity(濕度), and visibility(能見度)in the area.
Using this data, the scientists compared rainfall on Mount Hua to rainfall in the nearest city, Huayin, on days with different levels of visibility. When the air was clear and people could see as far as 20 km, the scientists found that 65% more rain fell on the mountain than in the city.
But when the air was smoggy, allowing only 8 km of visibility through the mist, the mountain received just 20% more rain than the city. The new data supports the theory that pollution affects rainfall.
Some scientists believe that there are other explanations for the numbers. It’s possible, for example, that natural particles(微粒)in the air, rather than particles produced by pollution, are affecting visibility.
小題1:According to the 1st paragraph, air pollution is changing the following EXCEPT ______.
A.the temperature B.the amount of rain
C.the habit of eatingD.the amount of snow
小題2:According to the passage, what will probably happen when the wet air in the sky gets colder?
A.It will probably rain or snowB.It will probably be cloudy.
C.It will probably windD.It will probably become dry.
小題3:Why did the team led by a scientist go to Mount Hua?
A.They wanted to pay a visit to Mount Hua.
B.They wanted to collect the data for their theory.
C.They wanted to measure Mount Hua.
D.They wanted to have a good rest on Mount Hua.
小題4:You can most probably read the passage in _______.
A.a(chǎn) travel guide
B.a(chǎn) telephone book
C.a(chǎn) cartoon book

The latest research suggests that the key factor separating geniuses from the merely accomplished is not I.Q., a generally bad predictor of success. Instead, it’s purposeful practice. Top performers spend more hours practising their craft. It you wanted to picture how a typical genius might develop, you’d take a girl who possessed a slightly above average language ability. It wouldn’t have to be a big talent, just enough so that she might gain some sense of distinction. Then you would want her to meet, say, a novelist, who coincidentally shared some similar qualities. Maybe the writer was from the same town, had the same family background, or shared the same birthday.
This contact would give the girl a vision of her future self. It would hive her some idea of a fascinating circle who might someday join. It would also help if one of her parents died when she was 12, giving her a strong sense of insecurity and fuelling a desperate need for success. Armed with this ambition, she would read novels and life stories of writers without end. This would give her a primary knowledge of her field. She’s be able to see new writing in deeper ways and quickly understand its inner workings.
Then she would practise writing. Her practice would be slow, painstaking and error-focused. By practising in this way, he delays the automatizing process. Her mind wants to turn conscious, newly learned skills into unconscious. Automatically performed skills. By practising slowly, by breaking skills down into tiny parts and repeating, she forces the brain to internalize a better pattern of performance. Then she would find an adviser who would provide a constant stream of feedback, viewing her performance form the outside, correcting the smallest errors, pushing her to take on tougher challenges. By now she is redoing problems—how do I get characters into a room—dozens and dozens of times. She is establishing habits of thought she can call upon in order to understand or solve future problems.
The primary quality our young writer possesses is not some mysterious genius. It’s the ability to develop a purposeful, laborious and boring practice routine; the latest research takes some of the magic out of great achievement. But it underlines a fact that is often neglected. Public discussion is affected by genetics and what we’re “hard-wired” to do. And it’s true that genes play a role in our capabilities. But the brain is also very plastic. We construct ourselves through behaviour.
小題1:The passage mainly deals with________.
A.the function of I.Q. in cultivating a writer
B.the relationship between genius and success
C.the decisive factor in making a genius
D.the way of gaining some sense of distinction
小題2:By reading novels and writers’ stories, the girl could________.
A.come to understand the inner structure of writing
B.join a fascinating circle of writers someday
C.share with a novelist her likes and dislikes
D.learn from the living examples to establish a sense of security
小題3:In the girl’s long painstaking training process, ________.
A.her adviser forms a primary challenging force to her success.
B.her writing turns into an automatic pattern of performance
C.she acquires the magic of some great achievement
D.she comes to realize she is “hard-wired” to write
小題4:What can be concluded from the passage?
A.A fuelling ambition plays a leading role in one’s success
B.A responsible adviser is more important than the knowledge of writing.
C.As to the growth of a genius, I.Q. Doesn’t matter, but just his|her effort.
D.What really matters is what you do rather then who you are.

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(特點) 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(學(xué)步者) learn much faster than males how to pick up nonverbal cues(非言語暗示) 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.
小題1:The passage mainly discusses__________.
           
A.how sex differences are demonstrated in social relations
  
B.how hormone determines sex differences
  
C.why there are differences between males and females
  
D.why men and women have different social roles
小題2:Which of the following is true of women's nurturing nature according to the passage?
A.It is not inborn in any sense.
B.It is inspired by women’s families.
C.It is caused by social prejudice.
D.It is partly biological in origin.
小題3:The Harvard Law School example in paragraph 3 suggests that_________.
A.women are not as competitive as men
B.law is not the fight profession for women
C.women are as excellent as men when they are young
D.a(chǎn)cademic qualities are not equal to performance
小題4:Which of the following statement is true according to paragraph 4?
A.Men leaders should consult colleagues and subordinates more often.
B.Female leaders' success is due to their imitating male leaders.
C.Men and women are different in their leadership style.

Against the supposition that forest fires in Alaska, Canada and Siberia warm the climate, scientists have discovered that cooling may occur in areas where burnt trees allow more snow to mirror more sunlight into space.
This finding suggests that taking steps to prevent northern forest fires to limit the release of greenhouse gases may warm the climate in northern regions. Usually large fires destroyed forests in these areas over the past decade. Scientists predict that with climate warming, fires may occur more frequently over the next several centuries as a result of a longer fire season. Sunlight taken in by the earth tends to cause warming, while heat mirrored back into space tends to cause cooling.
This is the first study to analyze all aspects of how northern fires influence climate. Earlier studies by other scientists have suggested that fire in northern regions speed up climate warming because greenhouse gases from burning trees and plants are released into the atmosphere and thus trap heat.
Scientists found that right after the fire, large amounts of greenhouse gases entered the atmosphere and caused warming. Ozone(臭氧) levels increased, and ash from the fire fell on far-off sea ice, darkening the surface and causing more radiation from the sun to be taken in. The following spring, however, the land within the area of the fire was brighter than before the fire, because fewer trees covered the ground. Snow on the ground mirrored more sunlight back into space, leading to cooling.
“We need to find out all possible ways to reduce the growth of greenhouse gases in the atmosphere.” Scientists tracked the change in the amount of radiation entering and leaving the climate system as a result of the fire, and found a measurement closely related to the global air temperature. Typically, fire in northern regions occurs in the same area every 80 to 150 years. Scientists, however, found that when fire occurs more frequently, more radiation is lost from the earth and cooling results. Specifically, they determined when fire returns 20 years earlier than predicted, 0.5 watts per square meter of area burned are soaked up by the earth from greenhouse gases, but 0.9 watts per square meter will be sent back into space. The net effect is cooling. Watts are used to measure the rate at which energy is gained or lost from the earth.
小題1:According to the new findings, taking steps to prevent northern forest fires may __________.
A.result in a warming climate
B.cause the forest fires to occur more frequently
C.lead to a longer fire season
D.protect the forests and the environment there
小題2:The following are all the immediate effects after a forest fire EXCEPT __________.
A.large amounts of greenhouse gases enter the atmosphere
B.the levels of ozone which is a type of oxygen increase
C.snow on the ground mirrors more sunlight back into space
D.a(chǎn)shes from the fire fall on the ice surface and take in more radiation from the sun
小題3:Earlier studies about northern forest fires __________.
A.a(chǎn)nalyze all aspects of how northern fires influence climate
B.indicate that forest fires will pollute the atmosphere
C.suggest that people should take measures to protect environment
D.suggest that the fires will speed up climate warming
小題4:The underlined phrase “soak up” in the last paragraph most probably means __________.

Sports shoes that work out whether their owner has done enough exercise to warrant time in front of the television have been devised in the UK.
The shoes — named Square Eyes — contain an electronic pressure sensor and a tiny computer chip to record how many steps the wearer has taken in a day. A wireless transmitter(傳話器) passes the information to a receiver connected to a television, and this decides how much evening viewing time the wearer deserves, based on the day’s efforts.
The design was inspired by a desire to fight against the rapidly ballooning waistlines among British teenagers, says Gillian Swan, who developed Square Eyes as a final year design project at Brunel University to London, UK. “We looked at current issues and childhood overweight really stood out,” she says. “And I wanted to tackle that with my design.”
Once a child has used up their daily allowance gained through exercise, the television automatically switches off. And further time in front of the TV can only be earned through more steps.
Swan calculated how exercise should translate to television time using the recommended daily amounts of both. Health experts suggest that a child take 12,000 steps each day and watch no more than two hours of television. So, every 100 steps recorded by the Square Eyes shoes equals precisely one minute of TV time.
Existing pedometers (計步器) normally clip onto a belt or slip into a pocket and keep count of steps by measuring sudden movement. Swan says these can be easily tricked into recording steps through shaking. But her shoe has been built to be harder for lazy teenagers to cheat. “It is possible, but it would be a lot of effort,” she says. “That was one of my main design considerations.”
小題1:According to Swan, the purpose of her design project is to ________.
A.keep a record of the steps of the wearer
B.deal with overweight among teenagers
C.enable children to resist the temptation of TV
D.prevent children from being tricked by TV programs
小題2:Which of the following is true of Square Eyes shoes?
A.They regulate a child’s evening TV viewing time.
B.They determine a child’s daily pocket money.
C.They have raised the hot issue of overweight.
D.They contain information of the receiver.
小題3:What is stressed(強(qiáng)調(diào))by health experts in their suggestion?
A.The exact number of steps to be taken.
B.The precise number of hours spent on TV.
C.The proper amount of daily exercise and TV time.
D.The way of changing steps into TV watching time.
小題4:Compared with other similar products, the new design ________.
A.makes it difficult for lazy teenagers to cheat
B.counts the wearer’s steps through shaking
C.records the sudden movement of the wearer
D.sends teenagers’ health data to the receiver
小題5:Which of the following would be the best title for the text?
A.Smart Shoes Decide on Television Time
B.Smart Shoes Guarantee More Exercise
C.Smart Shoes Measure Time of Exercise
D.Smart Shoes Stop Childhood Overweight

A strong wind can be a dangerous thing — sometimes it is powerful enough to knock you off your feet. But to plants, the wind is a source of new life, carrying them or their spores (孢子) thousands of miles.
A NASA satellite called QuikSCAT has discovered highways of wind over the Earth's oceans. Scientists believe these invisible roads may explain why many nonflowering plants, such as mosses (苔) and lichens (地衣), grow where they do.
The satellite is able to send microwaves (微波) from space to the surface of the ocean. The pattern of signals that come back shows which way the winds are blowing.
Using this data, the scientists studied a group of islands in the southern hemisphere (半球), near Antarctica.Winds tend to blow anticlockwise (逆時針) in this region, but there are lots of local differences.
When the researchers compared these local patterns to botanical (植物學(xué)) data, they found that the wind had an important effect on where species of mosses, lichens, and other nonflowering plants grow.
For example, Bouvet Island and Heard Island, share 30 per cent of their moss species, 29 per cent of liverworts (葉苔), and 32 per cent of lichens — even though they are 4,430 kilometers apart. In contrast, Gough Island and Bouvet Island, separated by just 1,860 kilometers of sea, share only 16 per cent of mosses and 17 per cent of liverworts. They have no lichens in common.
Ferns (蕨類植物) and flowering plants don't travel as well in the wind, so they don't show the same kinds of distribution (分布) patterns.
小題1:This story is about _____.
A.the discovery of wind highwaysB.how wind travels
C.how wind affects different plantsD.one function of the wind
小題2:The underlined word "data" in the fourth paragraph means _____.
A.signalB.patternC.informationD.research
小題3: Which of the following is wrong?
A.Bouvet Island, Heard Island and Gough Island are all in the southern hemisphere.
B.Winds in the researched area blow anti-clockwise.
C.The scientists shouldn't base this research on how winds affect where ferns grow.
D.Without the discovery of QuikSCAT, the research wouldn't have made sense.
小題4: Which of the following diagrams shows the correct position of the islands?

On the afternoon of September27, 2008, Astronaut Zhai Zhigang became the first Chinese man to walk in space on Saturday, clambering(爬上,攀登) out of China's Shenzhou VII space craft in a technological feat(成就,功績)that made the Chinese people excited.

"I'm feeling quite well. I greet the Chinese people and the people of the world," Zhai said as he climbed out of the craft at around 16:40 Beijing time, a historic achievement telecast live on CCTV. Tens of millions of Chinese viewers gathered before TV screens to watch the moment.
Chinese President Hu Jintao and other top leaders had appeared at the Beijing Aerospace Control Center to watch the live transmission of Zhai's spacewalk.
Zhai, 42, chosen by an expert team for the first "out-of-capsule activity," showed a red national flag, helped by colleague Liu Boming, who also briefly popped his head out of the capsule.
Zhai slowly made his way towards a test sample of solid lubricant(潤滑劑)outside the capsule, took a sample and handed it to Liu.
Zhai safely returned inside the craft after about 20 minutes. The walk marked the highpoint of China's third manned space journey, which has received widespread media coverage.
Zhai wore a $4.4 million Chinese-made suit weighing 120-kg. Liu wore a Russian-made one and acted as an assistant.
The third crew member, Jing Haipeng, monitored the ship from inside the re-entry module. w.w
