第一节（共15小题；每小题2分，满分30分）

　　阅读下列短文，从每题所给的四个选项（A、B、C和D）中，选出最佳选项，并在答题卡上将该项涂黑。

A

　　Soon it may be harder to stop and smell the roses.

　　Growing levels of air pollution from power plants and automobiles have reduced flower fragrances (芬芳) by up to 90 percent in the US.That is compared with pre-industrial levels,a new study has found.

　　The trend is unpleasant for human noses,but may be life - threatening for bees and butterflies.

　　"Many insects find flowers by folowing the scent(香味) produced by those flowers," said the studies lead author Jose D.Fuentes,an environmental scientist at the University of Virginia.

　　"The increasing pollution makes it difficult for them to locate the flowers and feed on their nectar(花蜜)."

　　Scientists have alrady known that flowers produce scent molecules(分子) that bond with pollutants.The process breaks down the plants' sweet smell.

　　With more pollution in the air,the scent molecules don't remain effective as long and travel shorter distances on the wind.

　　The new study suggests that in the mid - 19th century,when pollution levels were first recorded,scent molecules would have been able to travel some 1,000 to 1,200 meters.

　　Today,in the polluted air found downwind of large cities,scentst may only make it some 200 to 300 meters.

　　The report was recently published in the journal,Atmospheric Environment.

　　Bee farmers have reported that bee populations are dropping dramatically in many parts of the world in recent years. Could these missing scents be a factor?

　　Scientists trying to hind the cause of bee population declines have blamed bacteria,pesticides,and even cellphone radiation.

　　Jay Evans,an entomologist(昆虫学者) at the US Department of Agriculture's bee research laboratory,was interested in the new study.But he says he hasn't seen bee behavior that suggests trouble with scents.

　　"Over the last couple of summers I don't think the bees in this area were bringing in much less food,"he said.

　　"It might be that they had to work harder,but it seems like as long as there were bees to collect food they were finding flowers somewhere."

　　But Fuentes fears that the fading smell of flowers may stress insects that are already faced with other threats.

　　"The effects shown in these studies will simply exacerbate whatever the bees are going through right now,"he said.

　　"It's something that is really worthwhile paying attention to."

　　56.What's the passage mainly about?

　　　A.How greatly air plooution affects our lives.

　　　B.Effects of air pollution on bee populations.

　　　C.Measures to fight air pollution.

　　　D.The rapid decline of bee populations in the world.

　　57.According to the passage,Jay Evans probably agrees that ______ .

　　　A.bees are the insect that suffers most from air pollution

　　　B.bees are at risk of dying out owing to air pollution

　　　C.the fading smell of flowers doesn't affect bees so greatly as was thought

　　　D.as is often the case,bees fail to locate the flowers because of the missing scents

　　58.The word"exacerbate" in the last paragraph but one probably means ______.

　　　A.worsen B.improve C.get rid of D.decrease

　　59.Which of the following is NOT true according to the passage?

　　　A.The more air pollution there is in a region,the greater the destruction of the flower scents.

　　　B.Bacteria,pesticides,and cellphone radiation are blamed for causing the decline of bees.

　　　C.The scent molecules produced by flowers in a less polluted environment oculd travel longer and farther.

　　　D.Air pollution does more harm to insects such as bees and butterflies than human beings.

Many animals use some kinds of “language”. They use signals(信号) and the signals have meanings. For example, 1 a bee has found some food, it goes 　2 its home. 　3　 is difficult for a bee to tell 4 bees where the food is speaking to them, but it can do a little dancing. This tells the bees where the food is and 　5 it is.

Some animals show 　6 they feel by making sounds. It is not difficult to tell if a dog is angry because it barks. Birds make several different sounds and 　7 has its meaning. Sometimes we humans make sounds in the same way. We make sounds like “Oh” to 　8 how we feel about 9 or we 　10 something on our feet.

We humans have languages. We have words. These words have meaning of things, action, feeling or ideas. We are able to 11 each other information, to tell other people 12 we think or we feel. By writing down words, we can remember what has happened or 13 messages to people far away.

Languages, like people, live and die. If a language is not used by people, it is called a dead language. This language cannot live and grow because 　14 speaks it.

A living language, of course, is often spoken by people today. It grows and changes with time. New words are created, and some old words have 　15 meanings.

1. A. because 　　　　　　 B. since 　　　 　　　 C. when 　　　　　　 D. as

2. A. out of 　　　 B. back from　　　　 C. away from 　　　 D. back to

3. A. It　　　 　 B. This　 　　 　　　 C. That　 　　 D. He

4. A. each other 　 B. another　 　　　 C. the other 　 D. others

5. A. how long 　 B. how far away　 C. how many 　　　 D. how old

6. A. why　　 　　 B. which 　　 　　　 C. how　 　　 D. what

7. A. each　　　　　　　　　　 B. every 　　 　　　 C. all　 　　　 D. some

8. A. show　 　　 B. say　 　　 　　　 C. talk　 　　　 D. speak

9. A. everything　 　　　 B. something 　　　 C. nothing　 D. anything

10. A. put　　　　　　　 B. drop　 　　　　　 C. fall　 　　　　　　 D. set

11. A. give　　 　 B. put　　 　　　　　 C. show 　　 D. take

12. A. that　　 　　 B. which　 　　　 C. what　 　　 D. why

13. A. send　　 　　 B. bring　　 　　　 C. push　 　　 D. get

14. A. someone 　 B. no one　 　　　 C. anyone 　 D. everyone

15. A. new　　　 B. right　　 　　　　 C. real　 　　 D. good

　　A rabbit is running into its hole. You will ask,“What has this to do with language?”

　　Well, when a rabbit sees something dangerous, it runs away. Its tail moves up and down as it runs. When other rabbits see this tail moving up and down, they run too. They know that there is danger. The rabbit has told them something without making a sound. It has given them a signal.

　　Many other animals use this kind of language. When a bee has found some food, it goes back to its home. It cannot tell the other bees where the food is by speaking to them, but it does a little dance in the air. This tells the bees where the food is.

　　Some animals say things by making sounds. A dog barks, for instance, when a stranger comes near. A cat purrs when pleased. Some birds make several different sounds, each with its own meaning.

　　But human beings have something that no animal has--a large number of words which have the meanings of things, actions, feelings or ideas. We are able to give each other information, to tell or inform other people what is in our mind or how we feel. By writing words down we can remind ourselves of the things that have happened, or send messages to people far away. No animals can do this. No animal has the wonderful power of language.

　　No one knows how man learned to make words. Somehow he learned to make them. As centuries went by, he made more and more new words. This is what we mean by language.

　　People living in different countries made different kinds of words. Today there are about fifteen hundred different languages in the world. A very large English dictionary, for example, contains four or five hundred thousand words, but we do not know all these. The words we know are called vocabulary. We should try to make our vocabulary larger. Read as many books as possible. When we meet a new word, look it up in the dictionary. A dictionary is the most useful book.
