Stimulating drinks, such as tea or coffee, can also keep people awake. Inability to fall asleep is sometimes a symptom of emotional or mental disorders. Insomnia may also be caused by pain and, very rarely, it can be a symptom of a physical disease.The cause of insomnia may be easy to correct. The sufferer should check the mattress, bedclothes and bedroom temperature, and make any necessary changes. An eye mask keeps out the night and ear-plugs shut out sound. He should relax for an hour or two before bedtime, perha watching TV, or taking a warm bath. If he wakes during the night he should try turning on the light and reading for a while.

In June, 2007, a group of students from eight high schools in Winnipeg, the capital of Canada’s Manitoba province, will begin test-launching (试发射) a satellite the size of a Rubik’s cube. The one-kilogram Win-Cub satellite, named for its home city and its shape, will be put into low orbit. Once in space, it can perform for a few months or up to several years, communicating information that could help find the signs of earthquakes. There are 80 similar satellite projects worldwide, but this is the first high-school based program of its kind in Canada. 30 Manitoba high school students are having a hand in designing and building the satellite, in cooperation with aerospace (航空航天的) experts and 10 students from the University of Manitoba, and with support from two other organizations. The Win-Cube project is not something that goes it is real-world engineering, allowing high school students to have an opportunity to learn more about the exciting world of engineering through their participation in this challenging program. It is also taken as a wonderful example of the unique partnerships within Manitoba. Designing, building and launching a satellite with high-school participation will bring this world-class educational project into reality and Manitoba closer to space“These Manitoba high school students deserve congratulations for their enthusiasm, innovation (创新), and a strong love for discovery,” said Education, Citizenship and Youth Minister Peter Bjomson. “We want to make science more relevant, interesting and attractive to high school students by showing them how classroom studies can relate to practical experience in the workplace or, in this case, in space,” Bjomson added.&The Win-Cube program is mainly named at inspiring a strong desire for discovery on the part of the students. It also shows Manitoba’s devotion to research and innovation and the development of a skilled workforce—all important drivers of knowledge-based economic growth. 1.

EMost of us are used to seasons. Each year, spring follows winter, which follows autumn, which follows summer, which follows spring. And winter is colder than summer. But the earth goes through temperature cycles over much longer periods than those that we experience.Between 65,000 and 35,000 years ago, the planet was much colder than it is now. During that time the temperature also changed a lot, with periods of warming and cooling. Ice melted during the warm periods, which made sea levels rise. Water froze again during the cold periods.A new study from Switzerland sheds light on where ice sheets melted during the ice age.It now seems that the ice melted at both ends of the earth, rather than just in either northern or southern areas. This surprised the researchers from the University of Bern.Scientists have long assumed(认为) that most of the ice that melted was in the Northern hemisphere(半球) during the 30,000-year-long ice age. That belief was held because the North Pole is surrounded by land, while the South Pole is surrounded by the
Antarctic Ocean. It is easier for ice sheets to grow on land. If surrounded by sea, the ice can easily just slip to the ocean instead of building up.The researchers used a computer model to look at the ways the ice could melt and how it might affect sea levels. They compared these results to evidence(迹象) of how temperatures and currents actually changed during that time.The model showed that if it was only in the Northern hemisphere that ice melted, there would be a bigger effect on ocean currents(洋流) and sea temperatures than what actually happened. Studies suggest that melting just in the Southern hemisphere would have been impossible, too.The only reasonable conclusion, the scientists could make, was that the ice melted equally in the North and the South. It is still a mystery(谜) as to what caused the temperature changes that caused the ice to melt.72. We can learn from the text that _____.A.we have experienced temperature cycles since they beganB.what caused ice to melt is still unknownC. the planet was much colder than it is now between 65,000 and 35,000 years ago, during which time temperature hardly changedD. before the new study, scientists long believed that ice melted just in either northern or southern areas73. The underlined phrase "sheds light on" （in Paragraph 3） can be replaced by _____.A. throws doubts on B. beats down on C. makes it clear D. makes light of 74. The first two paragraphs were written _____.A. to lead up to the subject that ice melted during the 30,000-year-long ice ageB. to describe what the weather was like during the ice ageC. to compare climate nowadays with that of the ice ageD. to explain what a temperature cycle is 75. Which of the following best shows the relationship between ice, ocean currents and temperatures according to the text?A. Ice can easily slip into the ocean.B. Temperature and currents changed as a result of ice melting.C. Temperature changes lead to ice melting or water freezing, which in turn has an effect on ocean currents and temperature.D. Ice melted and then froze again due to temperature.

Most people agree that honesty is a good thing. But does Mother Nature agree? Animals can't talk, but can they lie in other ways? Can they lie with their bodies and behavior? Animal experts may not call it lying, but they do agree that many animals, from birds to chimpanzees, behave dishonestly to fool other animals. Why? Dishonesty often helps them survive. Many kinds of birds are very successful at fooling other animals. For example, a bird called the plover sometimes pretends to be hurt in order to protect its young. When a predator（猎食动物）gets close to its nest, the plover leads the predator away from the nest. How? It pretends to have a broken wing. The predator follows the "hurt" adult, leaving the baby birds safe in the nest.&&&&Another kind of bird, the scrub jay, buries its food so it always has something to eat. Scrub jays are also thieves. They watch where others bury their food and steal it. But clever scrub jays seem to know when a thief is watching them. So they go back later, unbury the food, and bury it again somewhere else.Birds called cuckoos have found a way to have babies without doing much work. How? They don't make nests. Instead, they get into other birds' nests secretly. Then they lay their eggs and fly away. When the baby birds come out, their adoptive parents feed them. Chimpanzees, or chimps, can also be sneaky. After a fight, the losing chimp will give its hand to the other. When the winning chimp puts out its hand, too, the chimps are friendly again. But an animal expert once saw a losing chimp take the winner's hand and start fighting again. Chimps are sneaky in other ways, too. When chimps find food that they love, such as bananas, it is natural for them to cry out. Then other chimps come running. But some clever chimps learn to cry very softly when they find food. That way, other chimps don't hear them,& and they don't need to share their food.As children, many of us learn the saying "You can't fool Mother Nature." But maybe you can't trust her, either.小题1:A plover protects its young from a predator by______.A．getting closer to its youngB．driving away the adult predatorC．leaving its young in another nestD．pretending to be injured小题2:By "Chimpanzees, or chimps, can also be sneaky" (paragraph 5), the author means______.A．chimps are ready to attack othersB．chimps are sometimes dishonestC．chimps are jealous of the winnersD．chimps can be selfish too小题3:Which of the following is true according to the passage?A．Some chimps lower their cry to keep food away from others.B．The losing chimp won the fight by taking the winner's hand.C．Cuckoos fool their adoptive parents by making no nests.D．Some clever scrub jays often steal their food back.小题4:Which of the following might be the best title of the passage?A．Do animals lie?B．Does Mother Nature fool animals?C．How do animals learn to lie?D．How does honesty help animals survive?

How far would you be willing to go to satisfy your need to know? Far enough to find out your possibility of dying from a terrible disease? These days that’s more than an academic question，as Tracy Smith reports in our Cover Story.There are now more than a thousand genetic(基因的)tests，for everything from baldness to breast cancer，and the list is growing．Question is do you really want to know what might eventually kill you? For instance，Nobel Prize-winning scientist James Watson，one of the first people to map their entire genetic makeup, is said to have asked not to be told if he were at a higher risk for& Alzheimer’(老年痴呆症)．“If I tell you that you have an increased risk of getting a terrible disease，that could weigh on your mind and make you anxious，through which you see the rest of your 1ife as you wait for that disease to hit you．It could really mess you up．”Said Dr．Robert Green，a Harvard geneticist.“Every ache and pain，”Smith suggested，could be understood as“the beginning of the e nd．”“That’s right．If you ever worried you were at risk for Alzheimer's disease，then every time you can’t find your car in the parking lot，you think the disease has started．”Dr．Green has been thinking about this issue for years．He led a study of people who wanted to know if they were at a higher genetic risk for Alzheimer’s．It was thought that people who got bad news would，for lack of a better medical term，freak out．But Green and his team found that there was “no significant difference”between how people handled good news and possibly the worst news of their lives．In fact，most people think they can handle it．People who ask for the information usually can handle the information，good or bad，said Green．小题1:The first paragraph is meant to ．A．ask some questionsB．introduce the topicC．satisfy readers，curiosity D．describe an academic fact小题2:Which of the following is true of James Watson?A．He is strongly in favor of the present genetic tests.B．He is more likely to suffer from Alzheimer's disease．C．He believes genetic mapping can help cure any disease.D．He doesn’t want to know his chance of getting a disease．小题3:According to Paragraphs 3 and 4，if a person is at a higher genetic risk，it is .A．advisable not to let him knowB．impossible to hide his diseaseC．better to inform him immediately D．necessary to remove his anxiety小题4:The underlined part“freak out”in Paragraph 5 is closest in meaning to .A．break downB．drop outC．leave offD．turn away小题5:The study led by Dr．Green indicates that people .A．prefer to hear good newsB．tend to find out the truthC．can accept some bad news D．have the right to be informed

Although the U.S. is so big and its people have so many different ethnic (racial) backgrounds, it is in some ways less varied than Europe. The English language is used almost everywhere in its American form. The American way of speaking has developed independently of England and is on the whole closer to what can be heard in Ireland.American instance of uniformity（一致性） is in habits and ways of living. From Boston to Los Angeles it is as far as from France to Central Asia, and from east to west there but everywhere people get up and go to bed at about the same time, eat the same kind of food, buy in the same kind of shops, work and rest at the same times of the day and have the same pattern of holidays. In most of the things that matter there is less difference between rich people and ordinary people, or between town and country, than in any single European nation.Although the United States covers so much land and the land produces far more food than the present population needs, its people are by now almost entirely an urban society. Less than a tenth of the people are engaged in agriculture, and most of the rest live in or around towns, large and small. Here the traditional most Americans do not live in small towns any more. Half the population now live in some thirty metropolitan（大城市的） areas.The fact that the United states has always been a single economic unit has contributed to uniformity. Modern industry favors large organizations, and it is no accident that the world’s biggest commercial firms are American. The people can choose between the products of competing manufacturers, but the products are all much alike. 小题1:In describing the uniformity in the U.S. the author does not mention thatA．the American people get up and go to work at the same time.B．the American people spend their holidays in the same pattern.C．the American people buy and eat the same kind of food.D．the American people have more or less the same income.小题2:What can we learn from the passage about the U.S. agriculture?A．The American farmers need more land than before.B．More and more Americans are interested in farming.C．It is quite modernized.D．It is now going backward.小题3:What is the feature of the U.S. modern industry according to the last paragraph?A．The production scale and the organizational scale are very big. B．It is a single economic unit that manufactures the same kind of products.C．There are more and more competing manufacturers.D．There are always a variety of products to choose from.小题4:What does “most of the things” in the second paragraph refer to? A．food, clothing and houses.B．Cars, computers and TV sets.C．Their wealth and income.D．Land, housing and bank savings.

Stop Spam!When I first got an e-mail account ten years ago, I received communications only from family, friends, and colleagues. Now it seems that every time I check my e-mail, I have an endless series of advertisements and other correspondence that do not interest me at all. If we want e-mail to continue to be useful, we need specific laws that make spamming (发送垃圾邮件) a crime.If lawmakers do not do something soon to prohibit spam, the problem will certainly get much worse. Computer programs allow spammers to send hundreds of millions of e-mails almost instantly. As more and more advertisers turn to spam to sell their products, individual (个人的) e-mail boxes are often flooded with spam e-mails. Would people continue to use e-mail if they had to deal with an annoying amount of spam each time?This problem is troubling for individuals and companies as well. Many spam e-mails contain computer viruses that can shut down the entire network of a company. Companies rely on e-mail for their employees to communicate with each other. Spam frequently causes failures in their local communications networks, and their employees are thus unable to communicate effectively. Such a situation results in a loss of productivity and requires companies to repeatedly repair their networks. These computer problems raise production costs of companies, which are, in the end, passes on to the consumer.For these reasons, I believe that lawmakers need to legislate (立法) against spam. Spammers should be fined, and perhaps sent to prison if they continue to disturb people. E-mail is a tool which helps people all over the world to communicate conveniently, but spam is destroying this convenience.小题1:What does the underlined word “correspondence” in the Paragraph 1 probably mean?&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&&A．messagesB．ideasC．connectionsD．programs小题2:According to the text, what is the major cause of the flooding spam?&&&A．Companies rely on e-mail for communications.B．More people in the world communicate by e-mails.C．Many computer viruses contain spam e-mail.D．More advertisers begin to promote sales through spam.小题3:According to Paragraph 3, who is the final victim of spam?&&&&&&&&&&&&&A．The businessB．The advertiser.C．The employeeD．The consumer.小题4:What is the purpose of the text?A．To inform.B．To educate.C．To persuade.D．To instruct.

We are not who we think we are.The American self-image is spread with the golden glow of opportunity. We think of the United States as a land of unlimited possibility, not so much a classless society but as a place where class is mutable—a place where brains, energy and ambition are what counts, not the circumstances of one's birth.The Economic Mobility Project, an ambitious research led by Pew Charitable Trusts, looked at the economic fortunes of a large group of families over time, comparing the income of parents in the late 1960s with the income of their children in the late 1990s and early 2000s. Here is the finding: "The 'rags to riches' story is much more common in Hollywood than on Main Street. Only 6 percent of children born to parents with family income at the very bottom move to the top.That is right, just 6 percent of children born to parents who ranked in the bottom of the study sample, in terms of income, were able to bootstrap their way into the top . Meanwhile, an incredible 42 percent of children born into that lowest are still stuck at the bottom, having been unable to climb a single rung of the income ladder.It is noted that even in Britain---a nation we think of as burdened with a hidebound class system-children who are born poor have a better chance of moving up. When the studies were released, most reporters focused on the finding that African-Americans born to middle-class or upper middle-class families are earning slightly less, in inflation-adjusted dollars, than did their parents.One of the studies indicates, in fact, that most of the financial gains white families have made in the past three decades can be attributed to the entry of white women into the labor force. This is much less true for African-Americans.The picture that emerges from all the quintiles, correlations and percentages is of a nation in which, overall, "the current generation of adults is better off than the previous one", as one of the studies notes.The median income of the families in the sample group was $55,600 in the late 1960s; their children's median family income was measured at $71,900. However, this rising tide has not lifted all boats equally. The rich have seen far greater income gains than have the poor.Even more troubling is that our nation of America as the land of opportunity gets little support from the data. Americans move fairly easily up and down the middle rungs of the ladder, but there is "stickiness at the ends" —four out of ten children who are born poor will remain poor, and four out often who are born rich will stay rich.小题1:What did the Economic Mobility Project find in its research?A．Children from low-income families are unable to bootstrap their way to the top.B．Hollywood actors and actresses are upwardly mobile from rags to riches.C．The rags to riches story is more fiction than reality.D．The rags to riches story is only true for a small minority of whites.小题2:It can be inferred from the undertone of the writer that America, as a classless society, should ________.A．perfect its self-image as a land of opportunityB．have a higher level of upward mobility than BritainC．enable African-Americans to have exclusive access to well-paid employmentD．encourage the current generation to work as hard as the previous generation小题3:Which of the following statements is TRUE according to the passage?A．The US is a land where brains, energy and ambition are what counts.B．Inequality persists between whites and blacks in financial gains.C．Middle-class families earn slightly less with inflation considered.D．Children in lowest-income families manage to climb a single rung of the ladder.小题4:What might be the best title for this passage?A．Social Upward Mobility.B．Incredible Income Gains.C．Inequality in Wealth.D．America Not Land of Opportunity.
