1、Woman workThough some people have suggested that women should return to housework in ｏｒｃｅｒto leave more jobs fｏｒmen, the idea has been rejected by both women ａｎｄ　men in public opinion polls.Lately some ｕｎｉｏｎofficials have suggested that too many women are employed in types of work more suitable fｏｒmen ａｎｄ　that women should step aside to make way fｏｒunemployed young men. They argue that women, especially women in their childbearing years,actually delay economic development ａｎｄ　result in productivity, poｏｒquality ａｎｄ　inefficiency.To solve the problem, they suggested that working women stay at home while their husbands ｏｒbrothers were given double wages. They argue that under these circumstances, families would remain their same level of income, ａｎｄ　women could run the house ａｎｄ　raise children much better,The suggestion, however , has been flatly rejected by 9 0ut of 10 people ____ .Some other people have suggested another way called "phased employment" theory. The theory suggests that a woman worker take leave from her job when she is seven months pregnant ａｎｄ　stay off the job until her baby reaches the age of 3. It suggested that women on leave receive 75 percent of their normal salary ａｎｄ　be allowed to return to work after the three-year period. This will benefit children, women, their families ａｎｄ　the society ａｎｄ　it definitely seems to be more acceptable than the suggestion that women return to their homes forever.【单选题】

2、African wild dogFinding a babysitter while you go out to work is, fｏｒexample, an inconvenience. Fｏｒthe African wild dog, one of the continent\'s most endangered carnivores （食肉动物), it\'s a matter of life ａｎｄ　death. A new research shows that once packs (兽群) fall below a certain size, they are not enough animals to both hunt food ａｎｄ　stay at home protecting the young.The African wild dog has declined drastically over the past century. Habitual loss (栖息地的丧失), persecution ａｎｄ　unexplained outbreaks of disease have all been blamed. Only 3, 000 to5,000 animals remain, ａｎｄ　the species is expected to go extinct within decades if the trend continues.Other large carnivores such as the spotted hyena (鬣狗) face similar pressures, yet are not declining. Now Franck Courchamp of Cambridge University has found a reason why. The dog\'s weakness lies in its social organization.Within each pack of up to 20 adults ａｎｄ　pups, only the dominant male ａｎｄ　female breed. The remaining animals help raise the pups, cooperating to hunt prey ａｎｄ　defend the kill from other carnivores.Because pups can\'t keep up on a hunt, large packs leave an adult behind to protect them from predators (捕猎者), which include lions ａｎｄ　hyenas. But leaving a babysitter also carries costs. A smaller hunting party is less able to tackle large prey ａｎｄ　to defend the kill. There is also one less stomach in which to carry food back to the den, ａｎｄ　one more mouth to feed when they get there.Courchamp investigated this awkward trade-off (权衡) by modeling how the costs of a babysitter change with decreasing pack size. This showed that packs of more than five adults should be able to feed all the pups ａｎｄ　still spare a babysitter. But with smaller packs, either the hunting ｏｒthe babysitting suffers, ｏｒthe animals have to compensate by increasing the number of hunting excursions which itself carries a cost to the pack.Field observations in Zimbabwe supported the model. Packs of five animals ｏｒfewer left pups unguarded more frequently than larger packs did. There was also evidence that when they did leave a babysitter, they were forced to hunt more often.A pack which drops below a critical size becomes caught in a vicious circle (恶性循环), says Courchamp, who is now at Paris-Sud University. "Poｏｒreproduction ａｎｄ　low survival further reduces pack size, culminating in (最终造成) failure of the whole pack. " ａｎｄ　deaths caused by human activity, says Courchamp, may be what reduce pack numbers to below the sustamable threshold. Mammal ecologist Chris Carbone at London\'s Institute of Zoology agrees. Maintaining the integrity of wild dog packs will be vitalin preserving the species, he says.Steps will be taken to protect the African wild dog.【单选题】

3、What Is the Coolest Gas in the Universe?What is the coldest air temperature ever recorded on the Earth? Where was this low temperature recorded? The coldest recorded temperature on Earth was -91℃ which occurred in Antarctica in 1983.We encounter an interesting situation when we discuss temperatures in space Temperatures in Earth orbit actually range from about +120℃ to -120℃. The temperature depends upon whether you are in direct sunlight ｏｒshade, Obviously, -120℃ is colder than our body can safely endure. Thank NASA science fｏｒwell-designed space suits that protect astronauts from these temperature extremes.The space temperatures just discussed affect only our area of the solar system . Obviously, it is hotter closer to the Sun ａｎｄ　colder as we travel away from the Sun. Astronomers estimate temperatures at Pluto are about -210℃. How cold is the lowest estimated temperature in the entire universe? Again, it depends upon your location. We are taught it is supposedly impossible to have a temperature below absolute zero, which is -273℃, at which atoms do not move. Two scientists, whose names are Cornell ａｎｄ　Wieman, have successfully cooled down a gas temperature barely _____ absolute zero. They won a Nobel Prize in Physics in 2001 fｏｒtheir work not a discovery in this car.Why is the two scientists\' work so important to science?In the 1920s, Satyendra Nath Bose was studying an interesting theory about particles we now call photons. Bose had trouble convincing Other scientists to believe so he contacted Albert Einstein. Einstein\'s calculations helped him theorize would behave as Bose thought but only at very cold temperatures.Scientists have also discovered that ultra-cold atoms can help them make the world\'s atomic clocks even more accurate. These clocks are so accurate today they would only lose one second every six million years! Such accuracy will help us travel in space because distance is velocity times time(d=vxt). With the long distances involved in space travel to know time as accurately as possible to get accurate distance.【单选题】

A.above

B.below

C.within

D.beyond

正确答案:A

答案解析:本段前面的句子说到最低温度不会低于-273℃，所以below、within、beyond都有悖于上述论述。只有above（高于）才与上文的意思相符。

4、New Product Will Save LivesDrinking water that looks clean may still contain bugs, which can cause illness. A small company called Genera Technologies has produced a testing method in three stages, which shows whether water is safe. The new test shows if water needs chemicals added to it, to destroy anything harmful. It was invented by scientist Dr. Adrian Patton, who started Genera five years ago. He ａｎｄ　his employees have developed the test together with a British water company.Andy Headland, Genera\'s marketing director, recently presented the test at a conference in the USA ａｎｄ　forecast good American sales fｏｒit. Genera has already sold 11 0fits tests at $42,500 a time in the UK ａｎｄ　has a further four on order. It expects to sell another 25 tests before the end of March. The company says it is the only test in the UK to be approved by the government.Genera was formed five years ago ａｎｄ　until October last year had only five employees； it now employs 14. Mr. Headlａｎｄ　believes that the company should make around $19 million by the end of the year in the UK alone.Before he ｓｅｔup Genera. Dr Parton had worked fｏｒa British water company.【单选题】

B.Wrong

C.Not mentioned

正确答案:C
