1、Human Space ExplorationWhile scientists are searching the cause of the Columbia disaster, NASA is moving ahead with plans to develop a new craft that would replace shuttles(航天飞机) on space station missions by2012 and respond quickly to space station emergencies.The space agency released the first set of mission needs and requirements several days ago for me orbital space plane (轨道航天飞机), which would be designed to transport a crew of four to and from the International Space Station.Although it includes few specifics, the plan states the orbiter(轨道航天飞机) will be safer cheaper and require less preparation time than the shuttle. It would be able to transport four crew members by 2012 though it would be available for rescue missions by 2010. NASA says the craft should be able to transport injured or ill space station crew members to "definitive(决定性的) medical care" within 24 hours.The release of the requirements showed NASA remains focused on the long-term priorities of space exploration, even as questions exist concerning the loss of Columbia and its seven member crew on February l, 2003.Expels at Marshall Space Flight Center in Huntsville, Alabama, have been working for years on a successor to the shuttle. The project, known as the Space Launch Initiative (倡议), was divided last year into two parts----one focusing on a future launch vehicle, the other on a space station orbiter. The orbiter is expected to be ready sooner.The program\'s managers say NASA officials have told them not to alter Space Launch Initiative in light of the Columbia disaster.U. S. President George W. Bush asked Congress for about US$1 billion for Space Launch Initiative in 2004, funds that would be almost equally split between the Orbital Space Plane and Next Generation Launch Technology.NASA plans to design the new space craft to .【单选题】

3、Why Is the Native Language Learnt So Well?How does it happen that children learn their mother tongue so well? When we compare them with adults learning a foreign language, we often find this interesting fact. A little child without knowledge or experience often succeeds in a complete mastery of the language. A grown-up person with fully developed mental powers, in most case, may end up with a faulty and inexact command. What accounts for this difference?Despite other explanations, the real answer in my opinion lies partly in the child himself, partly in the behavior of the people around him. In the first place, the time of learning the mother tongue is the most favorable of all, namely, the first years of life. A child hears it spoken from morning till night and, what is more important, always in its genuine form, with the right pronunciation, right intonation, and right use of words and right structure. He drinks in all the words and expressions, which come to him in a flash, ever-bubbling spring. There is no resistance: there is perfect assimilation.Then the child has, as it were, private lessons all the year round, while an adult language-student has each week a limited number of hours, which he generally shares with others. The child has another advantage: he hears the language in all possible situations, always accompanied by the right kind of gestures and facial expressions. Here there is nothing unnatural, such as is often found in language lessons in schools, when one talks about ice and snow in June or scorching heat in January. And what a child hears is generally what immediately interests him. Again and again, when his attempts at speech are successful, his desires are understood and fulfilled.Finally, though a child\'s "teachers" may not have been trained in language teaching, their relations with him are always close and personal. They take great pains to make their lessons easy.Compared with adults learning a foreign language, children learn their native language with ease.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:题干大意：与学习外语的成年人相比，儿童学习母语很容易。该问题考查考生对事实的判断。利用答案线索词adult和children，我们很快在第一段的段首句中发现children，而在随后的一句中发现adult。第一句的句意是：为什么孩子学习母语学得这么好？第二句的句意是：当我们把孩子和学习外语的成年人比较时，我们发现了这个有趣的事实。依据这两句判断该题实际上是对原文中这两个句子的总结说明。有的问题是考查考生的语言总结能力。

4、Fermi ProblemOn a Monday morning in July, the world\'s first atom bomb exploded in the New Mexico desert, Forty seconds later, the shook waves reached the base camp where the Italian-American physicist Enrico Fezmi and his team stood. After a mental calculation, Fermi announced to his team that the bomb\'s energy had equated 10,000 tons of TNT. The bomb team was impressed, but not surprised. Fermi\'s genius was known throughout the scientific world. In 1938 he had won a Nobel Prize. Four years later he produced the first nuclear chain reaction, leading us into the nuclear age. Since Fermi\'s death in 1954, no physicist has been at once a master experimentalist and a leading theoretician.Like all virtuosos (大师), Fermi had a distinctive style. He preferred the most direct route to an answer. He was very good at dividing difficult problems into small, manageable bits talent we all can use in our daily lives.To develop this talent in his students, Fermi would suggest a type of question now known as a Fermi problem. Upon first hearing one of these, you haven\'t the remotest notion of the answer, and you feel certain that too little information had been given to solve it, Yet when the problem is broken into sub-problems, each answerable without the help of expert. s or books, you can come close to the exact solution.Suppose you want to determine Earth\'s circumference without looking it up. Everyone knows that New York and Los Angeles are about 3,000 miles apart and that the time difference between them is three hours. Three hours is one-eighth of a day, and a day is the time it takes the planet to complete one rotation, so its circumference must be eight times 3000 0r 24000 miles. This answer differs from the true value, 24,902. 45 miles, by less than four percent.Ultimately the value of dealing with everyday problems the way Fermi did lies in the rewards of making independent discoveries and inventions. It doesn\'t matter whether the discovery is as important as determining the power of an atom or as small as measuring the distance between New York and Los Angeles. Looking up the answer, or letting someone else find it deprives you of the pleasure and pride that accompany creativity, and deprives you of an experience that builds up self-confide. Thus, approaching personal dilemmas as Fermi problems can become a habit that enriches your life.Dividing a big problem into small problems is a talent Fermi had and a talent that has practical value in life.【单选题】

A.Right

B.Wrong

C.Not mentioned

正确答案:A

答案解析:答案的依据是第2段的第3句，题干只不过是换了一种表达方式。

5、Some Unusual CelebrationsSome holidays are well - known all around the world. Among them are New Year\'s Eve Celebrations. Also days are common in honor of love and friendship, like Valentine\'s Day. Each country has its own special holidays too, to mark important events in its history. Schools, banks, and government offices all close on days like these. Some of the days people celebrate, however, are less serious. A few of them are really very strange.Of course, they are not strange to the people who celebrate them. Perhaps that is because the celebrations have long traditions. Consider April Fool\'s Day, for example. No one knows when or why it began. Today it is celebrated in many countries－France, England, and Australia, etc. On this day, people play practical jokes. Jokes are supposed to be funny, but these jokes do not make everyone laugh. The ones who laugh are the ones playing the jokes. The people they fool often get angry. Does celebrating this day make sense to you?Dyngus Day in Poland seems strange, too. On this day, it is traditional for boys to pour water over the heads of girls. Here is the strangest part: they do it to girls they like.Other unusual celebrations take place in a single city or town. A holiday called La Tomatina is celebrated in Bunol, Spain. Every year, in late August, big trucks carry more than 200,000 pounds of tomatoes into this little town. ____ For two hours, people in the streets throw tomatoes at each other. Everyone ends up red from head to toe.August 10 marks the start of the Puck Fair, an Irish festival with a very unusual tradition. People from the town of Killorglin go up into the mountains and catch a wild goat. They bring him back to town, put a crown on his head, and make him king for three days.There are also some celebrations that are really strange. In the United States, sometimes one person gets an idea for a new holiday and tries to get others to accept it. Whose idea was Public Sleeping Day? That one is on February 28. It may seem strange, but it sounds like more fun than the one on February 9. That is supposed to be Toothache Day.Do you like the idea of inventing a new holiday? If you do, then you will want to mark March 26 on your calendar. That is Make Up Your Own Holiday Day.【单选题】
