1、The Race into SpaceAmerican millionaire Dennis Tito will always be famous. He was the first tourist in space. "I spent sixty years on Earth ａｎｄ　eight days in space ａｎｄ　from my viewpoint, it was two separate lives," Tito explained. He loved his time in space. "Being in space ａｎｄ　looking back at earth is one of the most rewarding experiences a human being can have."This kind of experience isn\'t cheap. It cost $ 20 million. However, Tito achieved his dream, so he was happy. "Fｏｒme it was a life dream. It was a dream that began when didn\'t have any money," he told reporters.On 30 April 2002, Mark Shuttleworth became the world\'s second space tourist. Shuttleworth is a South African businessman. At the age of twenty - eight, he also paid $ 20 million fｏｒthe eight - day trip.Both Tito ａｎｄ　Shuttleworth bought their tickets from a company called Space Adventures. The company has around 100 people already on their waiting list fｏｒflights into space. The spaceship to take them doesn\'t exist yet.Many of the customers are people who like adventure. They are the kind of people who also want to climb Mount Qomolangma. Other customers are people who love space. However, these people are worried. Because it’s so expensive, only very rich people can go into space. They want space travel to be available to more people.That day may soon be here. Inter Orbital Systems (IOS) plans to send up to four tourists a week into space. The tours will depart from an islａｎｄ　in Tonga. The company promises a package that includes forty-five days of astronaut training in Russia ａｎｄ　California, seven days in space, ａｎｄ　a vacation in Tonga, fｏｒ$2 million.However, space flight is still very dangerous. Bill Readdy is NASA\'s deputy assistant administratｏｒfｏｒspace flight. He says that the chances of dying are about 1 in 500. Because of this, it may take time before space tourism really takes off. You might be able to go up, but will you come down?Bill Readdy thinks space flight is very dangerous.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:本题难度不大，找到答案依据不难。带着题干提示词Bill Readdy迅速回到文章定位。文中最后一段Bill Readdy谈到太空旅行死的几率是1/500，比较危险，所以本题正确，答案是A。

2、LanguageWhen one looks back upon the fifteen hundred years that are the life span of the English language, he should be able to notice a number of significant truths. The history of language is a history of constant change-at times a slow, almost imperceptible change, at other times a violent collision between two languages. Language a living growing organism, it has never been static. Another significant truth that emerges from such a study is that language at all times has been the possession not of one class orｇｒｏｕｐbut of many. At one extreme it has been the property of the common, ignorant folk, who have used it in the daily business of their living, much as they have used their animals ｏｒthe kitchen pots ａｎｄ　pans. At the other extreme it has been the treasure of those who have respected it as an instrument ａｎｄ　a sign of civilization, ａｎｄ　who have struggled by writing it down to give it some permanence, order, dignity, ａｎｄ　if possible, a little beauty.As we consider our changing language, we should note here two developments that are of special ａｎｄ　immediate importance to us. One is that since the time of the Anglo-Saxons there has been an almost complete reversal of the different relationship of words in a sentence. Anglo-Saxon(old English) was a language of many inflections. Modern English has few inflections. We must now depend largely on word ｏｒｃｅｒａｎｄ　function words to convey the meanings that the older language did by means of changes in the forms of words. Function words, you should understand, are words such as prepositions, conjunctions, ａｎｄ　a few others that are used primarily to show relationships among other words. A few inflections, however, have survived. ａｎｄ　when some word inflections come into conflict with word order,. there may be trouble fｏｒthe users of the language, as we shall see later when we turn our attention to such maters as WHO ｏｒWHOM ａｎｄ　ME ｏｒl. The second fact we must consider is that as language itself changes, our attitudes toward language forms change also. The eighteenth century, fｏｒexample, produced from various sources a tendency to fix the language into patterns not always ｓｅｔin ａｎｄ　grew, until at the present time there is a strong tendency to restudy ａｎｄ　re-evaluate language practices in terms of the ways in which people speak ａｎｄ　write.The authｏｒof these paragraphs is probably a (an) ____.【单选题】

A.historian

B.philosopher

C.anthropologist

D.linguist

正确答案:D

答案解析:此题考查考生的推测能力和词汇量，文章的具体细节，最适当的答案应该是D。作者很可能是一位语言学家。A选项（历史学家）和C选项（人类学家）也可以有点迷惑性。 B选项（哲学家）是最不符合的。

D.mostly

正确答案:A

答案解析:题干大意：看起来她非常不可能通过考试。画线词highly和very（非常）同义。completely：完全地；usually：通常地；mostly：主要地。故答案为A。

4、A Carrot a Day Keeps Cancer AwayAmong all the malignancies, lung cancer is the biggest killer: more than 100,000 Americans a year die of the disease. Giving up smoking is one of obvious way to reduce the risk, but another answer may lie in the kitchen. According to a new report, even heavy smokers may be protected from developing lung cancer by a simple dietary measure: a daily portion of carrots, spinach ｏｒany other vegetable ｏｒfruit containing a form of vitamin A called carotene.The finding, published in the British medical journal The Lancet, is part of a long-range investigation of diet ａｎｄ　disease. Since 1957 a team of American researchers has monitored the dietary habits ａｎｄ　medical histories of 2,000 middle-aged men employed by the Western Electric Co. in Chicago. Led by Dr. Richard Shelelle of Chicago\'s Rush-Presbyterian, St. Luke\'s Medical Center, the researchers recently began to sort out the links between the subjects\' dietary patterns ａｎｄ　cancer. Other studies of animals ａｎｄ　humans have suggested that vitamin A offers some protection against lung cancer. The correlation seemed logical, since vitamin A is essential fｏｒthe growth of the epithelial (上皮的) tissue that lines the airways of the lungs.Vegetables: But the earlier research did not distinguish between two different forms of the vitamin. "Preformed" vitamin A, known as retinol, is found mainly in liver ａｎｄ　dairy products like milk, cheese, butter ａｎｄ　eggs. But vitamin A is also made in the body from carotene, which is abundant in a variety of vegetables ａｎｄ　fruits, including carrots, spinach, squash, tomatoes, sweet potatoes ａｎｄ　apples.In the Western Electric study, Shekelle ａｎｄ　his colleagues found little correlation between the incidence of lung cancer ａｎｄ　the consumption of foods containing preformed vitamin A, but when they examined the data on carotene intake, they discovered a significant relationship. Among the488 men who had the lowest level of carotene consumption, there were fourteen cases of lung cancer, in aｇｒｏｕｐof the same size that ate the most carotene, only two cases developed. The apparent protective effect of carotene held up even fｏｒlongtime smokers but to a lesser degree.Further studies will be necessary before the link between lung cancer ａｎｄ　carotene can be firmly established. In the meantime, researchers warn against taking large numbers of vitamin A pills, because the tablets contain a form of the chemical that can be extremely toxic in high doses. Instead, they advise a well-balance diet that includes foods rich in carotene. Fｏｒa smoker, a half-cup of carrots every day might possibly make the difference between life ａｎｄ　death.Why do researchers warn against taking large numbers of vitamin A pills?【单选题】

A.The pills are hard to swallow.

B.The pills contain a chemical that can be toxic in high doses.

C.The pills are expensive.

D.The pills cause lung cancer.

正确答案:B

答案解析:根据最后一段，“因为该药片包含一种化学成分，大剂量服用时有巨毒”，因此答案B。

5、Stop Eating Too much"Clean your plate!"and" Be a member of the clean-plate club!" Just about every kid in the US has heard this from a parent ｏｒgrandparent. Often, it\'s accompanied by an appeal: "Just think about those starving orphans (孤儿) in Africa!" Sure, we should be grateful fｏｒevery bite of food. Unfortunately, many people in the US take too many bites. Instead of saying "clean the plate", perhaps we should save some food fｏｒtomorrow.According to news reports, US restaurants are partly to blame fｏｒthe growing bellies(肚子). A waiter puts a plate of food in front of each customer, with two to four times the amount recommended by the government, according to a USA Today story. Americans traditionally associate quantity with value ａｎｄ　most restaurants try to give them that. They prefer to have customers complain about too much food rather than too little.Barbara Rolls, a nutrition (营养) professｏｒat Pennsylvania State University, told USA Today that restaurant portion sizes began to grow in the 1970s, the same time that the American waistline(腰围) began to expand.Health experts have tried to get many restaurants to serve smaller portions. Now, apparently, some customers are calling fｏｒthis too. The restaurant industry trade magazine QSR reported last month that 57 percent of more than 4,000 people surveyed believed restaurants served portions that were too large; 23 percent had no opinion; 20 percent disagreed. But a closer look at the survey indicates that many Americans who can\'t afford fine dining still prefer large portions. Seventy percent of those earn at least $ 150,000 per year prefer smaller portions; but only 45 percent of those earning less than $25, 000 want smaller.It\'s not that working class Americans don\'t want to eat healthy. It\'s just that, after long hours at low-paying jobs, getting less on their plate hardly seems like a good deal. They live from paycheck (薪金支票) to paycheck, happy to save a little money fｏｒnext year\'s Christmas presents.(2008年)Why do American restaurants serve large portions?【单选题】

A.Because Americans have big bellies.

B.Because Americans associate quantity with value.

C.Because Americans are good eaters.

D.Because Americans are too weak.

正确答案:B

答案解析:题干问“为什么美国餐馆提供的食物量大”。参见文章第二段，传统上美国人把东西值不值跟数量联系在一起，因此餐厅给的食物分量大，乐于让顾客们抱怨饭菜给得太多而不乐于让他们抱怨饭菜给得太少。故正确答案为B。
