Space is a dangerous place. not only because of meteors (流星) but also because of rays from the sun and other stars. The Atmosphere again acts as our protective blanket on earth. Light gets through, and this is essential for plants to make the food which we eat. Heat, too, makes our environment endurable. Various kinds of rays come through the air from outer space, but enormous quantities of radiation from the sun are screened off. As soon as men leave the atmosphere they are exposed to this radiation but their spacesuits or the walls of their spacecraft, if they are inside, do prevent a lot of radiation damage.

    Radiation is the greatest known danger to explorers in space. The unit of radiation is called “rem”. Scientists have reason to think that a man can put up with far more radiation than 0.1 rem without being damaged; the figure of 60 rems has been agreed on. The trouble is that it is extremely difficult to be sure about radiation damage-a person may feel perfectly well, but the cells of his or her sex organs may be damaged, and this will not be discovered until the birth of deformed (畸形的) children or even grandchildren. Missions of the Apollo flights have had to cross belts of high radiation and, during the outward and return journeys, the Apollo crew accumulated a large amount of rems. So far, no dangerous amounts of radiation have been reported, but the Apollo missions have been quite short. We simply do not know yet how men are going to get on when they spend weeks and months outside the protection of the atmosphere, working in a space laboratory. Drugs might help to decrease the damage done by radiation, but no really effective ones have been found so far.

1. According to the first paragraph, the atmosphere is essential to man in that ______.

A. it protects him against the harmful rays from space    

B. it provides sufficient light for plant growth

C. it supplies the heat necessary for human survival      

D. it screens off the falling meteors

2. It can be inferred from the passage that ________.

A. the Apollo mission was very successful        

B. protection from space radiation is no easy job

C. astronauts will have deformed children or grandchildren

D. radiation is not a threat to well-protected space explorers

3. The best title for this passage would be ________.

A. The Atmosphere and Our Environment   B. Research on Radiation.

C. Effects of Space Radiation             D. Importance of Protection Against Radiation

Last week my youngest son and I visited my father at his new home in Tucson, Arizona. He moved there a few years ago, and I was eager to see his new place and meet his friends.

    My earliest memories of my father are a tall, handsome, successful man devoted to his work and his family, but uncomfortable with his children. As a child I loved him. He seemed unhappy with me unless I got straight A’s and unhappy with my boyfriends if their fathers were not as “successful” as he was. Whenever I went out with him on weekends, I used to struggle to think up things to say, feeling on guard.

    On the first day of my visit, we went out with one of my father’s friends for lunch at an outdoor café. We walked along that afternoon, did some shopping, ate on the street table, and laughed over my son’s funny facial expressions. Gone was my father’s critical (挑剔的) air and strict rules. Who was this person I knew as my father, who seemed so friendly and interesting to be around? What had held him back before?

    The next day dad pulled out his childhood pictures and told me quite a few stories about his own childhood. Although our times together became easier over the years, I never felt closer to him at that moment. After so many years, I’m at last seeing another side of my father. And in so doing, I’m delighted with my new friend. My dad, in his new home in Arizona, is back to me from where he was.

56. Why did the author feel bitter about her father as a young adult?

A. He was silent most of the time.

B. He was too proud of himself.

C. He did not love his children.

D. He expected too much of her.

57. When the author went out with her father on weekend, she would feel         .

A. nervous                 B. sorry                C. tired              D. safe

A. More critical.          B. More talkative

C. Gentle and friendly.     D. Strict and hard-working.

59. The underlined words “my new friend” in the last paragraph refer to          .

A. the author’s son                               B. the author’s father

C. the friend of the author’s father         D. the café owner

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 dangers. 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.

56. Why does the author mention the questions in Paragraph 1?

A. To express his doubts.

B. To compare different ideas.

C. To introduce points for discussion.

D. To describe the conditions on Earth.

57. 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.

58. The underlined word “spin-offs” in Paragraph 4 probably refers to­­_______ .

A. survival chances

B. potential resources

C. unexpected benefits

D. physical possessions

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

A. Our genetic make up.

B. Resources on the earth.

C. The adaptive ability of humans.

D. By-products in space exploration.

60. Which of the statements can best sum up the passage? 

A. Space exploration has created many wonders.

B. Space exploration provides the best value for money.

C. Space exploration can benefit science and technology.

D. Space exploration may help us avoid potential problems on Earth.
