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 (»ùÒò¹¹³É) 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 (DZÔÚµÄ) 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 (¸±²úÆ·) 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.

1£®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.

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 4 probably refers to ________. A£®survival chances B£®potential resources C£®unexpected benefits D£®physical possessions

4£®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. ¢õ.ÈÎÎñÐÍÔĶÁ

Disability

A disability is a physical or mental problem that makes it difficult or impossible for a person to walk, see, hear, speak, learn, or do other important things. Some disabilities last forever. 1.________ A disability can be something a person was born with. Or it can be the result of an illness or an accident.

2£®________ Physical disabilities may affect the eyes, the ears and the muscles. Some people with physical disabilities may use wheelchairs to move around.

A mental disability is a problem with the brain, or mind. Mental disabilities include developmental disabilities, mental illness, and learning disabilities. 3.________

With medical treatment or other help, people with disabilities can do many of the things that non¡Mdisabled people can do. 4.________ Many kinds of mental illnesses can be treated with medicines or other treatment. Organizations in community can help people with developmental disabilities to go to school, work or live on their own.

5£®________ It is a complex phenomenon, reflecting the interaction (Ï໥×÷ÓÃ) between features of a person's body and features of the society in which he or she lives. Overcoming the difficulties faced by people with disabilities requires us to remove environmental and social barriers.

A£®Others last for only a short time. B£®Disability is not just a health problem.

C£®A physical disability is a problem with the body. D£®Disability doesn't mean unable, and it isn't a sickness. E£®Disabilities make it harder to do normal daily activities.

F£®A person with a missing leg can learn to walk with a man¡Mmade leg.

G£®People with mental disabilities have trouble learning or getting along with other people.
