For many years, scientists couldn't figure out how atoms and molecules on the Earth combined to make living things. Plants, fish, dinosaurs, and people are made of atoms and molecules, but they are put together in a more complicated way than the molecules in the primitive ocean. What's more, living things have energy and can reproduce, while the chemicals on the Earth 4 billion years ago were lifeless.
　　After years of study, scientists figured out that living things, including human bodies, are basically made of amino acids and nucleotide bases. These are molecules with millions of hydrogen, carbon, nitrogen, and oxygen atoms. How could such complicated molecules have been formed in the primitive soup? Scientists were stumped.
　　Then, in 1953, two scientists named Harold Urey and Stanley L. Miller did a very simple experiment to find out what had happened on the Primitive Earth. They set up some tubes and bottles in a closed loop, and put in some of the same gases that were present in the atmosphere 4 billion years ago: water vapor, ammonia, carbon dioxide, methane, and hydrogen.
　　Then they shot an electric spark through the gases to simulate bolts of lightning on the ancient Earth, circulated the gases through some water, sent them back for more sparks, and so on. After seven days, the water that the gases had been bubbling through had turned brown. Some new chemicals were dissolved in it. When Miller and Urey analyzed the liquid, they found that it contained amino acids-the very kind of molecules found in all living things.
46. When did scientists come to realize how the atoms and molecules on the Earth combined to make living thing?
　　A. 4 billion years ago. B.1953. C. After seven days. D. Many years later.
47. Scientists figured out that human bodies are basically made of .

阅读下面短文，从每题所给的A、B、C、D四个选项中选出最佳选项，并在答题卡上将该项涂黑。
When John Milton, writer of “Paradise Lost”, entered Cambridge University, in 1625, he was already skilled in Latin after seven years of studying it as his second language at St. Paul’s School, London. Like all English boys who prepared for college in grammar schools, he had learned not only to read Latin but also to speak and write it smoothly and correctly. His pronunciation of Latin was English, however, and seemed to have sounded strange to his friends when he later visited Italy.
Schoolboys gained their skill in Latin in a bitter way. They kept in mind the rules to make learning by heart easier. They first made a word-for-word translation and then an idiomatic translation into English .As they increased their skill, they translated their English back into Latin without referring to the book and then compared their translation with the original. The schoolmaster was always at hand to encourage them. All schoolmasters believed Latin should be beaten in.
After several years of study, the boys began to write compositions in imitation of the Latin writers they read. And as they began to read Latin poems ,they began to write poems in Latin .Because Milton was already a poet at ten ,his poems were much better than those painfully put together by the other boys. During the seven years Milton spent at university, he made regular use of his command of Latin. He wrote some excellent Latin poems, which he published among his works in 1645.
41．What does the passage mainly tell about?
A．How John Milton wrote “Paradise Lost”. B．How John Milton studied Latin.
C．How John Milton became famous. D．How John Milton became a poet.

A. It has a strong Italian accent. B. It has an uncommon accent.　　
C. It was natural and easy to understand.　D. It was bad and difficult to understand.
43．It can be inferred from the passage that .
A．Milton’s training in Latin was similar to that of the other boys
B．Milton hadn’t learned any foreign language except Latin before going to college
C．Milton’s Italian friends helped him with Latin when talking
D．Milton’s classmates learned Latin harder but worse than Milton.

C．Schoolboys were expected to master Latin in a short time.
D．Schoolboys had to study Latin in a hard way.

If you ask people to name the one person who had the greatest effect on the English language, you will get answers like “Shakespeare,” “Samuel Johnson,” and “Webster,” but none of these men had any effect at all compared to a man who didn’t even speak English – William the Conqueror.
Before 1066, in the land we now call Great Britain lived peoples belonging to two major language groups. In the west-central region lived the Welsh, who spoke a Celtic language, and in the north lived the Scots, whose language, though not the same as Welsh, was also Celtic. In the rest of the country lived the Saxons, actually a mixture of Anglos, Saxons, and other Germanic and Nordic peoples, who spoke what we now call Anglo-Saxon (or Old English), a Germanic language. If this state of affairs had lasted, English today would be close to German.
But this state of affairs did not last. In 1066 the Normans led by William defeated the Saxons and began their rule over England. For about a century, French became the official language of England while Old English became the language of peasants. As a result, English words of politics and the law come from French rather than German. In some cases, modern English even shows a distinction between upper-class French and lower-class Anglo-Saxon in its words. We even have different words for some foods, meat in particular, depending on whether it is still out in the fields or at home ready to be cooked, which shows the fact that the Saxon peasants were doing the farming, while the upper-class Normans were doing most of the eating.
When Americans visit Europe for the first time, they usually find Germany more “foreign” than France because the German they see on signs and advertisements seems much more different from English than French does. Few realize that the English language is actually Germanic in its beginning and that the French influences are all the result of one man’s ambition.
36. The two major languages spoken in what is now called Great Britain before 1066 were _________.
A. Welsh and Scottish B. Nordic and Germanic
C. Celtic and Old English D. Anglo-Saxon and Germanic
37. Which of the following groups of words are, by inference, rooted in French?
A. president, lawyer, beef B. president, bread, water
C. bread, field, sheepD. folk, field, cow
38. Why does France appear less foreign than Germany to Americans on their first visit to Europe?
A. Most advertisements in France appear in English.
B. They know little of the history of the English language.
C. Many French words are similar to English ones.
D. They know French better than German.
39. What is the subject discussed in the text?
A. The history of Great Britain.
B. The similarity between English and French.
C. The rule of England by William the Conqueror.
D. The French influences on the English language.
40. Which of the following statements is NOT true?
A. The Old English was originated from Germanic language.
B. William the Conqueror invaded England and conquered the whole country in 1066.
C. William the conqueror’s great ambition was to introduce French words into the English language.
D. According to the text, Shakespeare’ contribution to the development of the English language is less than that William the conqueror made.

The United Nations says forty million people or so around the world went hungry in 2008，mainly because of higher food prices. Early estimates from the UN Food and Agriculture Organization (FAO) show that 963 million people did not get enough to eat.
World food prices have dropped since early 2008．Prices of major crops have decreased by more than half from their height earlier last year. But they remain high compared to earlier years．
But FAO official Hafez Ghana says lower prices have failed to end the food crisis（危机）in many poor countries．"For millions in developing countries," he says, "getting enough food every day to live an active and healthy life is a distant dream.”
The FAO says food shortage is a threat to people's health．Today, two-thirds of the world's undernourished people live in just a few countries. These are India, the Democratic Republic of Congo, Bangladesh, Indonesia, Pakistan, Ethiopia and so on.
A report on food insecurity warns that the current economic crisis could send even more people into hunger and poverty.
In sub-Saharan Africa, the percentage of the people who continually go hungry fell from 34% in 1997 to 30% in 2008．But the FAO says Ghana is the only country that has reached two sets of hunger reduction targets．These were set by the 1996 World Food Summit and the Millennium Development Goals．The main reason is the growth in agricultural production in Ghana.
The FAO says some countries in Southeast Asia like Thailand and Vietnam have made progress in hunger reduction goals．But South Asia and Central Asia haven't, and North Korea is still in hot water.
31. What FAO official Hafez Ghana says implies ＿．
A. it's easy but takes long to provide people with enough food
B. enough food can make people more active and healthier
C. there is difficulty solving the food shortage in a short time
D. people in developing countries will never get enough food
32. Ghana has reached the targets of hunger reduction mainly because of ＿．
A. the still high food prices
B. the donation of developed countries
C. the two targets of hunger reduction
D. the growth in agricultural production
33. The underlined word "undernourished" in Para. 4 probably means ＿．
A. hungry and unhappyB. unhealthy for lack of food
C. not fat because of poverty D. undeveloped and poor
34. Which country has not made progress in hunger reduction?
A. North KoreaB. ThailandC. Vietnam D. Ghana
35. What is the best title of this passage?
A. The food production of the world
B. The hunger reduction target of the FAO
C. The food shortage around the world
D. The solution to the global food shortage

第三部分：阅读理解（共20小题，每小题2分，满分40分）
第一节：(共15小题，满分30分)
阅读下列短文，从每题所给的A、B、C和D项中，选出最佳选项，并在答题卡上将该项涂黑。
Children start out as natural scientists, eager to look into the world around them. Helping them enjoy science can be easy: there’s no need for a lot of scientific terms or expensive lab equipment. You only have to share your children’s curiosity. Firstly, listen to their questions. I once visited a classroom of seven-year-olds to talk about science as a job. The children asked me “textbook questions” about schooling, salary and whether I liked my job. When I finished answering, we sat facing one another in silence. Finally I said, “Now that we’re finished with your lists, do you have questions of your own about science?”
After a long pause, a boy raised his hand, “Have you ever seen a grasshopper(蚱蜢) eat? When I try eating leaves like that, I get a stomachache. Why?”
This began a set of questions that lasted nearly two hours.
Secondly, give them time to think. Studies over the past 30 years have shown that, after asking a question, adults typically wait only one second or less for an answer, no time for a child to think. When adults increase their “wait time” to three seconds or more, children give more logical(符合逻辑的), complete and creative answers.
Thirdly, watch your language. Once you have a child involved in a science discussion, don’t jump in with “That’s right” or “Very good”. These words work well when it comes to encouraging good behavior. But in talking about science, quick praise can signal that discussion is over. Instead, keep things going by saying “That’s interesting” or “I’d never thought of it that way before”, or coming up with more questions or ideas.
Never push a child to “Think”. It doesn’t make sense, children are always thinking, without your telling them to. What’s more, this can turn a conversation into a performance. The child will try to find the answer you want, in as few words as possible, so that he will be a smaller target(目标) for your disagreement.
Lastly, show, don’t tell. Real-life impressions of nature are far more impressive than any lesson children can learn from a book or a television program. Let children look at their fingertips through a magnifying glass(放大镜), and they’ll understand why you want them to wash before dinner. Rather than saying that water evaporates(蒸发), set a pot of water to boil and let them watch the water level drop.
26. According to the passage, children are natural scientists, and to raise their interest, the most important thing for adults to do is _______.
A. to let them see the world around

A. ask them to answer quickly
B. wait for one or two seconds after a question
C. tell them to answer the next day
D. wait at least for three seconds after a question
