【题目】‘As I stood in front of the grave (墓) of President Richard Nixon, I was thinking about the time 25 years ago when this president helped bring the United States and China closer together. Young people of our two countries should help this relationship grow.’

This remark (评论) was made by a Shanghai student when speaking to his fellow students at the Nixon Library in California, U.S.A. He was one of 80 middle school students from China attending a month-long ‘Youth Summit’. The Summit was to mark the 25th anniversary (周年) of President Nixon’s journey to China, which was the turning point in China-U.S. relations.

The Youth Summit was aimed at increasing understanding and friendship between young students of the two countries through visits and discussions. Seventy-five American students were selected to visit China. They also visited the Nixon Library on July 21 before leaving for Beijing the next day. The head of the Library said he was pleased to see the American and Chinese students talking and laughing together.

One Chinese student said, ‘I didn’t find it particularly difficult to talk with Americans. We have our differences, but we have a lot in common. Dialogue is good for us.’

【题目】Why should mankind explore space? Why should money, time and effort be spent exploring and researching something with so few apparent benefits? Why should resources be spent on space rather than on conditions and people on Earth? These are questions that, understandably, are very often asked.

Perhaps the best answer lies in our genetic makeup (基因构成)as human beings. What drove our ancestors to move from the trees into the plains, and on into all possible areas and environments? The wider the spread of a species, the better its chance of survival. Perhaps the best reason for exploring space is this genetic tendency to expand wherever possible.

Nearly every successful civilization has explored, because by doing so, any dangers in surrounding areas can be identified and prepared for. Without knowledge, we may be completely destroyed by the danger. With knowledge, we can lessen its effects.

Exploration also allows minerals and other potential (潜在的)resources to be found. Even if we have no immediate need of them, they will perhaps be useful later. Resources may be more than physical possessions. Knowledge or techniques have been acquired through exploration. The techniques may have medical applications which can improve the length or quality of our lives. We have already benefited from other spin-offs including improvements in earthquake prediction, in satellites for weather forecasting and in communications systems. Even non-stick pans and mirrored sunglasses are by-products (副产品)of technological developments in the space industry!

While many resources are spent on what seems a small return, the exploration of space allows creative, brave and intelligent members of our species to focus on what may serve to save us. While space may hold many wonders and explanations of how the universe was formed or how it works, it also holds clangers. The danger exists, but knowledge can help human beings to survive. Without the ability to reach out across space, the chance to save ourselves might not exist.

While Earth is the only planet known to support life, surely the adaptive ability of humans would allow us to live on other planets. It is true that the lifestyle would be different, but human life and cultures have adapted in the past and surely could in the future.

D. To describe the conditions on Earth.

2 What is the reason for exploring space based on Paragraph 2?

A. Humans are nature-born to do so.

B. Humans have the tendency to fight.

C. Humans may find new sources of food.

D. Humans don’t like to stay in the same place.

3 The underlined word “spin-offs" in Paragraph 4probably refers to ________ .

A. survival chances

B. potential resources

C. unexpected benefits

D. physical possessions

4 What makes it possible for humans to live on other planets?

A. Our genetic makeup.

B. Resources on the earth.

C. The adaptive ability of humans.

D. By-products in space exploration.
