It is natural that children are curious (好奇的) about the world around them. For example, they want to know how their hearts beat. They want to know why the ocean water tastes salty.
As children grow up, they become curious about different kinds of things. When they are babies, they are interested in the parts of their bodies and in the smiles of their mothers. They become interested in the physical world around them: the plants, the animals, the sky. Later, they become interested in the things that people have made: wheels, bicycles, cars. And when they are adults, their curiosity continues. Sometimes this curiosity leads to a career (生涯、职业) in science.
Scientists spend their lives trying to find out about the world．Those who work with the earth sciences study the earth, the oceans, and the sky. Other scientists who study living things work with the biological sciences. A third group of scientists study the physical sciences, e. g. physics, chemistry .
These scientists have already discovered a lot about our world．For example, they tell us why your heart beats fast when you run. They say that when you are quiet, your heart normally beats sixty-five or seventy-five times a minute. Your heart is a pump (泵) that pumps blood to all parts of the body. The blood carries oxygen and nutrition. When you run, your muscles work very hard and use the nutrition that the blood carries to them. The muscles need oxygen, too . So your brain sends a signal to the heart. The signal means that the muscles need more nutrition and oxygen. Then the heart beats fast and sends blood quickly to the muscles. It may beat 90 to 140 times a minute.
Of course, scientists cannot answer all of our questions. If we ask, “Why does the ocean water taste salty” scientists will say that the salt comes from rocks. When a rock gets very hot or very cold, it cracks. Rain falls into cracks. The rain then carries the salt into the earth and into the rivers. The rivers carry the salt into the ocean. But then we ask , “What happens to the salt in the ocean? The ocean does not get saltier every year.” Scientists are not sure about the answer to this question.
We know a lot about our world, but there are still many answers that we do not have, and we are curious.

Molly Wilson had been a dancer and a mother for many years when she decided to sail round the world to raise money for charity.
As a child she had trained as a ballet dancer, but at 15 she had grown too tall for classical ballet, so she became a member of a pop dance team.
She got married, and after she had children she retired from show business to bring them up. They grew up, and when they were 18 they left home.
She says, “When I decided to do the round-the-world race, my husband thought I was bored because the children had left home. He was also worried because I had never sailed before. I was not bored, but I had met some people who told me about the race.
They had taken part in it, but they had only done one section, say, from New Zealand to Australia. I wanted to do the whole ten-month journey.”
Before Molly left she did a lot of training, but it hadn’t prepared her for the worst weather which they experienced. She tells one story. “One night the sea was very rough and it was very cold. I had gone downstairs when a hug
e wave smashed into the boat and injured two men on the deck. One of the men couldn’t move because he had broken his leg. They were taken to hospital by helicopter. That was the worst time.”
By the end of October last year, she had raised more than £50,000 for charity.
She says, “Sometimes I ask myself, what did I do? How did I do it? But then I think, it’s the same as being a dancer. Before I left on the trip, I had trained hard. I had got very fit and had prepared myself completely. Then on the trip I was simply a good team member.”
1. When I decided to do the round-the-world race, my husband thought I felt_________.
A. dissatisfied because I had nothing better to do at home

3. Which of the following is closest in meaning to “rough” in Para. 5?
A. not exact B. not smooth because of huge waves
C. difficult D. pleasant
4. The last paragraph suggests that _________.
A. she should be kind to other team members during the trip

MONTREAL (Reuters) – Crossing the US-Canada border to go to church on a Sunday cost an American ＄10,000 for breaking Washington’s strict new security（安全）rules.
The expensive trip to church was a surprise for Richard Albert, who lives on the Canadian border. Albert often crosses the border like the other half-dozen people of Township 15. The nearby Quebec village of St. Pamphile is where they shop, eat and go to church. There are many such situations in these areas along the largely unguarded 5,530-mile border between Canada and the US, which in some cases actually
runs down the middle of streets or through bu
ildings.
As a result, Albert says he did not expect any problems three weeks ago when he returned home to the US after attending church in Canada as usual. The US customs（海关）station in this area is closed on Sundays, so he just drove around the locked gate, as he had done every weekend since the gate appeared last May, following a tightening of border security. Two days later, Albert was told to go to the customs office, where an officer told him he had been caught on camera crossing the border illegally（非法）.
Ottawa has given out special passes to some 300 Americans in that area so they can enter the country when Canadian customs stations are closed, but the US stopped a similar program last May. That forces the people to a 200-mile detour along hilly roads to get home through another border checkpoint.
Albert has requested that the customs office change their decisions on the fine, but he has not attended a Sunday church since. “I feel like I’m living in a prison,” he said.

A．an American working in a Canadian church
B．a Canadian living in a Quebec village
C．a Canadian working in a customs station
D．an American living in Township 15
2．Albert was fined because he____________.
A. broke the American security rules
B．failed to obey traffic rules
C．worked in St. Pamphile without a pass
D．damaged the gate of the customs o
ffice
3．According to paragraph 4, how can Americans in that area get home ?
A．They have to drive through the town.
B．They have to race across the fields.
C．They have to drive to the mountain area.
D．They have to drive in a roundabout(绕道的) way.
4．What would be the best title for the text?
A．A Cross-country Trip B．An Expensive Church Visit
C．An Unguarded BorderD．A Special Border Pass
The desire to make explorations is born with man. Wherever his imagination goes, man also has a strong wish to go. A large part of human history is connected with the exploration of the world in which we live. Again and again people have set out with surprising courage and patience to look into unknown regions and lands to see what had not yet been seen, to make known the unknown. With kites, balloons and aircraft they left the ground to pass through the lower atmosphere. Now the outer space receives their attention.
Why should man take the trouble of exploring space? It is hard to list the specific practical benefits that will result in. But one knows, from past experience in other areas, that man will surely see and discover new things in space that will increase our scientific knowledge, and this new knowledge will find its
way into valuable practical uses. What we learn about man himself, from his experience in space, and from the effects of space and the space flight environment on him, will be extremely valuable. The new techniques developed to carry out the exploration of space, and to keep man alive in space, will certainly find practical uses in everyday life in some way. The areas that will benefit are manifold. They include communication, generation of power, transportation and travel, food production, materials, fuels and many others. But to say exactly what the practical results will be is almost impossible.

3. The author seems to be in favor of ____.
A. the exploration of space
B. doubting the necessity of the space exploration
C. exploring more in space than in sea

A. that can be made use of
B. that can be learned as knowledge
C. that are obtained from experience
D. helping us make further exploration

The Food and Drug Administration is, again, threatening to impose(征税) milk and meat from cloned animals on a public tha
t opposes the technology and its products.
Respected polls report that more than 60% of Americans think animal cloning is immoral, and that most people said they wouldn’t knowingly eat the products even if the FDA approved them. But because the FDA would allow cloned meat and milk to be sold without identifying labels, consumers wouldn’t be able to avoid them. The FDA has consistently tilted toward those who want cloned milk and meat in our food. Agency officials have repeatedly asserted that science shows cloned milk and meat are safe for humans. But the FDA has never published the complete scientific studies it says support that claim.
The argument that cloning is safe for animals is unconvincing. Cloned meat and milk offer no public economic benefits. Having cloned cows produce more milk wouldn’t reduce milk prices. US farmers produce 
more milk than we drink, and the government is required to buy the surplus. Since 2000, dairy support programs have cost taxpayers more than $ 5 billion.
Most important, this first decision to advance animal biotechnology raises ethical issues beyond the FDA’s expertise（专家意见）. Techniques used to clone animals will advance the ability to clone humans－and create animals with human genes. Neither the agency nor animal scientists are qualified to tell us whether and when it is ethically acceptable for humans to alter the essential nature of animals. We need a national discussion, including ethicists and religious leaders, to consider the wisdom of cloned and transgenic animals. Given the risk of unintended consequences, we should proceed cautiously. The president should halt further FDA action on cloning and set in motion(运作) a process for beginning this broader discussion.
1. The author’s attitude towards cloning is __________.
A. standing in the middle B. opposed C. approving D. supportive
3. In US many people buy cloned foods __________.
A. to support the new technique
B. because FDA approved them
C. because they cannot tell which is cloned food
D. because they cannot read the labels.
3. From the text we know that cloning technique ___________.
A. developed well enough to clone human beings
B. may cause unintended bad results to human beings
C. will bring more unexpected economic benefits
D. is supported by ethicists and religious leaders
4. What’s the best title of this passage?
A．Public Is Against Cloned Food B．Benefits of Cloned Food
C．Cloned Food Is Illegal D．Technique in Cloned Food
