閱讀下列短文, 從每題所給的選項(xiàng)（A、B、C和D）中，選出最佳選項(xiàng)，并在答題卷上將該項(xiàng)涂黑。

      A

   One night recently, I was driving down a two-lane highway at about 60 miles an hour. A car approached from the opposite direction at about the same speed. As we passed each other, I caught the other driver’s eye for only a second. I wondered whether he might be thinking, as I was, how dependent we were on each other at that moment. I was relying on him not to fall asleep, not to be put off by a phone conversation, not to cross over into my lane and bring my life to a sudden end. Though we had never spoken a word to each other, he relied on me in just the same way.

Multiplied a million times over, I believe that is the way the world works. At some level, we all depend upon one another. Sometimes that dependence requires us simply not to do something like crossing over the double yellow line. And sometimes it requires us to act cooperatively, with friends or even with strangers.

As technology shrinks our world, the need increases for cooperative action among nations. In 2003, doctors in five nations were quickly organized to identify the SARS virus, which saved thousands of lives. The threat of international terrorism has shown itself to be a similar problem, one requiring team action by police and intelligence forces across the world. We must recognize that our fates are not ours alone to control.

In my own life, I’ve put great stock in personal responsibility. But, as time has passed, I’ve also come to believe that there are moments when one must rely upon the good faith and judgment of others. so, while each of us faces the case of driving alone down a dark road, what we must learn is that the approaching light may not be a threat, but a shared moment of trust.

The author considers it very important ______.

A. to drive with a company              B. to have personal independence

C. to gain certain responsibility             D. to share trust and cooperation

The author said that they depended on each other in the same way because ______.

A. the approaching car was very dangerous

B. they both drove their car at a terrific speed

C. he might be killed out of the other’s careless driving

D. it was dark and the road was not wide enough

From the second paragraph, we know the author drew the important lesson from ______.

A. only one experience                   B. many similar experiences

C. a driver on a dark road               D. many friends and strangers

The need for cooperation increases because ______.

A. peoples’ fates can’t be controlled by themselves

B. certain viruses can spread in a quick way

C. terrorism can happen everywhere and every day

D. the world has become much more dangerous

We can infer from the last paragraph that the author has ______.

A. believed in one’s own personal responsibility

B. counted upon himself alone in everything

C. had no trust in others’ good faith and judgment

D. had accomplished a change on his viewpoint of life

While researchers have long shown that tall people earn more than their shorter counterparts, it's not only social discrimination that accounts for this inequality -- tall people are just smarter than their height-challenged peers, a new study finds.
"As early as age three -- before schooling has had a chance to play a role -- and throughout childhood, taller children perform significantly better on cognitive tests," wrote Anne Case and Christina Paxson of Princeton University in a paper published by the National Bureau of Economic Research.
The findings were based primarily on two British studies that followed children born in 1958 and 1970, respectively, through adulthood and a U.S. study on height and occupational choice.
Other studies have pointed to low self-esteem, better health that accompanies greater height, and social discrimination as culprits(罪犯) for lower pay for shorter people.
But researchers Case and Paxson believe the height advantage in the job world is more than just a question of image.
"As adults, taller individuals are more likely to select into higher paying occupations that require more advanced verbal and numerical skills and greater intelligence, for which they earn handsome returns," they wrote.
For both men and women in the United States and the United Kingdom, a height advantage of four inches equated with a 10 percent increase in wages on average.
But the researchers said the differences in performance crop up long before the tall people enter the job force. Prenatal care(產(chǎn)前護(hù)理) and the time between birth and the age of 3 are critical periods for determining future cognitive ability and height.
"Prenatal care and prenatal nutrition are just incredibly important, even more so than we already knew," Case said in an interview.
Since the study's data only included populations in the United Kingdom and the United States, the findings could not be applied to other regions, Case said.
And how tall are the researchers?
They are both about 5 feet 8 inches tall, well above the average height of 5 feet 4 inches for American women.
51. What can be learnt from the study of Anne Case and Christina Paxson is that ______.
A. the reason for lower pay for shorter people is social discrimination
B. taller children perform significantly better on cognitive test
C. tall people earn more than shorter counterparts
D. prenatal care and prenatal nutrition are less important than we already knew
52. Which period is the most important for determining future cognitive ability and height?
A. between age 3 and schooling         B. between birth and the age of 3
C. the whole childhood                   D. between 1958 and 1970
53. The underlined phrase “crop up” in the Eighth Paragraph is closest in meaning to ______.
A. get in       B. rise up        C. come up       D. stand up
54. The best title for this passage would be _______.
A. Tall people earn more than shorter counterparts 
B. A study on height and occupational choice
C. The difference between tall people and short people 
D. Taller people are smarter

Science Daily -------- Dutch ecologist Roxina Soler and her colleagues have discovered that subterranean（地下的）and above ground herbivorous（食草的）insects can communicate with each other by using plants as telephones. Subterranean insects issue chemical warning signals through the leaves of the plant. Thus, aboveground insects are warned that the plant is already “ occupied”.
In recent years it has been discovered that different types of aboveground insects develop slowly if they feed on plants that also have subterranean residents and vice versa（反之亦然）. It seems that a system has developed through natural selection, which helps the subterranean and aboveground insects to communicate with each other. This avoids unnecessary competition.
Through the “green telephone lines”, subterranean insects can also communicate with a third party, namely caterpillars（毛蟲(chóng)）. Parasitic wasps（寄生的黃蜂）lay their eggs inside aboveground insects. The wasps also benefit from the signals sent by the leaves, The communication between subterranean and aboveground It is still not clear how widespread this phenomenon is.
This research was carried out at the Netherlands Institute for Ecology by Roxina Soler, Jeffrey Harvey, Martijn Bezemer, Wim van der Putten and Louise Vet. was funded by the Free Competition of NOW Earth and Life Sciences.
41. After finding a plant occupied by root-eating insects, aboveground insects will usually ________.
A. send out warning signals
B. choose to leave the plant
C. fight with the root-eating insects
D. compete with them for the same plant
42. Aboveground insects will develop more quickly if their food plants _______.
A. have more green leaves
B. get more water and sunlight
C. are often visited by parasitic wasps
D. are not occupied by root-eating insects
43. The underlined part “a third party” in Paragraph 4 refers to ______.
A. caterpillars               B. root-eating insects    
C. parasitic wasps          D. aboveground insects
44. What is the best title for the passage ?
A. Insects use plants as “telephones”
B. How do animals avoid competition
C. The living habit of different insects
D. Communication between different insects

May 16th               Wednesday                                                  Sunny

They used to call her “the witch（女巫）”, but today I found things were different.

         My legs were too short to reach the floor from up there on the big chair. I was so afraid. My legs started to shake.

         It was the first time I had been to the principal’s（校長(zhǎng)的） office. And I knew what she was going to ask me.

         Why had I been running on the concrete（混凝土） in the playground? Why hadn’t I followed the school rules?

         The principal’s secretary was sitting at her desk. She kept asking me questions like whether I liked school and what grade I was in. I didn’t want to talk to her, so I just gave one-word answers.         

         Then she asked what my dad did. But I didn’t really know what he did, so I made something up. “He plays basketball for the Boston Celtics,” I said.

         The secretary just looked at me, and said nothing more.

         Just then, the door to the principal’s office opened. There she was, the woman that everyone called “the witch”.

         Was she really that bad? I was surprised to see her office walls were bright yellow, and there were some nice pictures on the desk.

         She told me about the pictures. I was surprised that she had a family and a kid, just like me.

         Then she asked how my family was. It turned out that she had known me since I was only a few weeks old. I was happy to hear that. If she knew my mum, then I wouldn’t get into much trouble.

 She cleaned the cut on my knee and told me to be more careful. She also told me about the rules of the playground. But she didn’t punish or shout at me. And I forgot all the bad things I had heard about “the witch”. I had met her and I knew she was nice.

A. the writer                            B. the writer’s father                C. the secretary    D. the principal

　  C. Running in the playground was allowed by the school rules.

　  D. The writer’s father was an excellent basketball player.

3．Which word can replace the underlined phrase “made up” (in Paragraph 6)?

　  A. Told.                            B. Invented.                  C. Minded.                  D. Memorized.

4. How did the writer find the principal in the end?

　  A. Terrible.                 B. Kind.                        C. Proud.                     D. Strict.
