第二大题： 用所给词的正确形式填空。

It was my first trip to India, alone. One day, as I was walking

through a local market, a ten-year-old boy came over and begged me to buy a book, which had the words "Interesting India" on its cover. I bought it, thinking that when I returned home it would remind me of my wonderful Indian adventure. The book claimed that India's people were very welcoming of tourists, and never tried to cheat them. As I read I felt deeply touched by these warm words.

Suddenly, a monkey came down from a nearby tree, snatched the book from my hand and took it away, along with my bag which contained all my belongings. I couldn't do anything but stand and stare. Then a man approached me and asked if I wanted my belongings back. He said it would cost me five US dollars. I had no other choice left , so I agreed to pay, but only after my bag was returned.

He blew a whistle and the monkey immediately threw the bag down. I picked it up and gave him the money. I later learned that the man made his living this way: tricking tourists. This was the worst thing I ever experienced in "Interesting India".

答案：11、was walking 12、which 13、of 14、to cheat 15、 it

16、but 17、 if 18、 left 19、 the 20、 worst

Passage A

A new study shows that rising levels of planet-warming gases may reduce important nutrients in food crops.

Researchers studied the effects of one such gas—carbon dioxide—on rice. The researchers grew rice plants in a controlled environment. They set carbon dioxide levels to what scientists are predicting for our planet by the end of the century. They found that the resulting rice crops had lower than normal levels of vitamins, minerals and protein. The researchers said the effects of planet-warming gases would be most severe for the poorest citizens in some of the least developed countries. These people generally eat the most rice and have the least complex diets, they noted.

In the experiment, scientists grew 18 kinds of rice in fields in China and Japan. They pumped carbon dioxide gas over the plants in an effort to create the atmosphere of the future. Rice grown under high carbon dioxide conditions had, on average, 13 to 30 percent lower levels of four B vitamins and 10 percent less protein. The crops also had 8 percent less iron and 5 percent less zinc（锌）an rice grown under normal conditions. However, vitamin E levels increased by about 13 percent on average.

The results are bad news, “especially for the nutrition of the poorer population in less-developed countries,” said the University of Tokyo’s Kazuhiko Kobayashi, who helped to write the report. That includes about 600 million people in Indonesia, Cambodia, Myanmar, Bangladesh, Laos and other nations, mainly in Southeast Asia, the report said.

One of the scientists is Sam Myers of Harvard University in the American state of Massachusetts. He said that findings like this are an example of the surprises climate change create. “My concern is there are many more surprises to come,” he said.

Myers noted that pollution, loss of some species, destruction of forests, and other human activities are likely to produce unexpected problems. He said that you cannot completely change all the natural systems that living organisms have grown to depend on over millions of years without having effects come back to affect our own health.

The new study suggests a way to lower the nutritional harm of climate change. One way, Kobayashi said, is grow different forms of rice that have shown to be more resistant to higher carbon dioxide levels.

21. Which county would be influenced most by planet-warming gases according to the text?( )

A. China B. Myanmar C. America D. Britain

22. How is Paragraph 3 mainly developed? ( )

A. By comparison. B. By giving examples.

C. By analyzing causes. D. By describing a process.

23. What does the underlined sentence in Paragraph 5 mean? ( )

A. Climate change will be difficult to predict.

B. Climate change will lead to more good effects.

C. Climate change will be harmful to environment.

D. Climate change will cause more unexpected problems.

24. Which of the following statements is true according to the text? ( )

A.Myers said we could change all the natural systems for the sake of our health.

B.The poorest people in all the least developed countries would be influenced most.

C.The researchers grew 18 kinds of rice in China and Japan in a controlled environment.

D.Protein in rice grown under high carbon dioxide conditions is increased by 10 percent.

Passage B

Plants are boring. They just sit there (光合作用)while animals have all the fun. Right? Not so much. A new study has found that there is a long history of interactions between ants and plants. The ant and plant co-evolution(协同进化)started with ants feeding on plants and plants evolving ant-friendly features.

Plants make a number of different structures that are specific for ant use. Some plants have evolved features that persuade ants into defending them from attack from other insects and even mXXXXXmmXXXXXl?. XXXXXhXXXXX?XXXXX ?nXXXXXludXXXXX hollow thorns that XXXXXnt? will live ?n??dXXXXX, or XXXXXXXXXXtra nXXXXXXXXXXtXXXXXr (琼浆) XXXXXn lXXXXXXXXXXvXXXXX? or stems for the ants to eat. Some ants will just cheat and take the nectar and run, but some will stick around and attack anything that tries to hurt the plant. Other plants get ants to help them move their seeds around, by providing them with rich food packets attached to the seeds. The ant will pick up the seed and carry it away, eat the food packet, and leave the seed - often in a nutrient-rich area where it'll grow better, and since it's farther away from its parent, they won't have to compete for resources.

But scientists weren't sure how the evolutionary relationship between ants and plants got started. If evolution is an arms race between species developing ways to make use of their neighbors, then scientists wanted to know whether plants or ants fired the first shot. It was a chicken-and-egg question, whether things started with ants developing behaviors to take advantage of plants, or plants evolving structures to take advantage of ants.
