【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 dangersThe danger exists, but knowledge can help human being 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. Humans don’t like to stay in the same place.

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

A. Our genetic makeup.

C. The adaptive ability of humans.

D. By-products in space exploration.

【题目】Driving to a friend's house on a recent evening, I was attracted by the sight of the full moon rising just above my friend’s rooftops. I stopped to watch it for a few moments, thinking about what a pity it was that most city people, myself included usually miss sights like this because we spend most of our lives indoors.

My friend had also seen it. He grew up living in a forest in Europe, and the moon meant a lot to him then. It had touched much of his life.

I know the feeling. Last December I took my seven-year-old daughter to the mountainous jungle of northern India with some friends. We stayed in a forest rest-house with no electricity or running hot water. Our group had campfires outside every night, and indoors when it was too cold outside. The moon grew to its fullest during our trip. Between me and the high mountains lay three or four valleys. Not a light shone in them and not a sound could be heard. It was one of the quietest places I have ever known, a bottomless well of silence. And above me was the full moon, which struck me deeply.

Today our lives are filled with glass, metal, plastic and fiber-glass. We have televisions, cell phones, pagers, electricity, heaters and ovens and air-conditioners, cars, computers.

Struggling through traffic that evening at the end of a tiring day, most of it spent indoors, I thought: before long, I would like to live in a small cottage. There I will grow vegetables and read books and walk in the mountains And perhaps write, but not in anger. I may become an old man there, and wear the bottoms of my trousers rolled and measure out my life in coffee spoons. But I will be able to walk outside on a cold silent night and touch the moon.

3What impressed the writer most in the mountainous jungle of northern India?

A. No modern equipment B. Complete silence.

C. The nice moonlight D. The high mountains

4Modern things (Paragraph 4) are mentioned mainly to______.

A. show that the writer likes city life very much

B. tell us that people greatly benefit from modern life

C. explain that people have fewer chances to enjoy nature

B. show the love for the moonlight

C. advise modern people to learn to live

D. want to communicate longing for modern life

【题目】Like all animal species, plant species must spread their off-spring to suitable areas where they can grow and pass on their parents' genes. Young animals generally spread by walking or flying. Because plants don't have that ability, they must somehow hitchhike(搭顺风车). Some plant seeds scatter by blowing in the wind or floating on water. Many other plant species, though, trick an animal into carrying their seeds. How do they do this? They enclose the seeds within a tasty fruit and advertise the fruit's ripeness by its colour or smell. The hungry animal collects and swallows the fruit, walks or flies off, and later spits out the seeds somewhere far from its parent tree. Seeds can thereby be carried for thousands of miles. It may surprise you to learn that plant seeds can resist digestion. In fact, some seeds actually require passage through an animal's body before they can grow.

Wild strawberries offer a good example of hitchhiking tactics. When strawberry seeds are still young and not yet ready to be planted, the surrounding fruit is green, sour and hard. When the seeds finally mature, the berries turn red, sweet, and tender. The change in the berries'colour serves as a signal to birds which then eat the strawberries, fly off, and eventually spit out the seeds.

Naturally, strawberry plants didn't set out with a conscious intention of attracting birds only when their seeds were ready to be dispersed . Nor did birds set out with the intent of planting strawberries. Rather, strawberry plants evolved through natural selection. The sweeter and redder the final strawberry, the more birds spread its ripe seeds ; the greener and more sour the young strawberry, the fewer birds destroyed the seeds by eating berries before the seeds were ready.

【1】 What does the underlined word "dispersed" in the third para-graph mean?

A. Spread. B. Eaten. C. Born. D. Planted.

【2】 For plants, which of the following is NOT a way of spreading their offspring to suitable areas?

A. Hitchhiking.

B. Blowing in the wind.

C. Floating on water.

D. Tracking an animal.

【3】 Which strategy does the example of wild strawberries describe?

A. The conscious intent of attracting birds.

B. Spreading by walking.

C. Spreading by flying.

D. The strategy of taking a lift.

【4】 Why does the author describe how strawberry seeds are spread?

A. To show plants are good at adapting to the environment.

B. To show strawberry's special way.

C. To show the plant has different ways of spreading seeds.

D. To show the mystery of plant.

【5】 What's the passage mainly about?

A. How animals disperse offspring.

B. How plants disperse their offspring.

C. Plant evolution.

D. Plants'hitchhiking on animals.
