The Great Wall of China is one of Beijing’s biggest draws for tourists; despite its fame and ubiquity in postcards across the world, it rarely fails to attract tourists at the first proper sight.Yet the authorities open only certain sections of the wall as fit for viewing, and few get to visit the unauthorized sections. Fewer still are aware of the existence of at least one part of the Wall that remains in almost original condition, nearly 1,500 years after construction of legendary fortification began. But there’s a good reason for this – it’s underwater.

American journalist Steven Schwankert has been diving since age 10. It was though his setting – up of a diving school that Schwankert came to explore some of lesser – known areas of China’s lakes – and discovered the underwater Wall under a reservoir.  “The most fascinating piece of diving I ever did in China must be the Great Wall. I managed to find out about it via the Internet. It wasn’t difficult to get to Pan Jiakou in Hebei Province, near the East Qing Tomb about 4 hour’s drive from Beijing. Why do I want to dive the Great Wall? Why do people want to walk on the Great Wall? It’s the same answer.”

There are, however, advantages of visiting the Great Wall in a diving suit over being on foot. The water acts as a preservative by preventing the kind of mass tourism that has brought trouble on other parts of the Wall. “Unlike the people who walk in the Wall, we as divers never need to actually touch it. I’ve dived twice there, the last time in July. I found that the water then was much deeper than it was before – 13 meters deep.” When he first dived, parts of the Wall were visible above the surface. Now even the guard tower is completely submerged. “It’s better that the Wall is deep under water, as there are lots of boats coming in and out around that area. Their wave action could potentially damage the brickwork. So, the deeper, the better.”

1.Steven Schwankert is most interested in           .

         A.collecting photos of the Wall     B.walking along on the Wall

         C.diving the underwater Wall       D.visiting some famous lakes

2.What does the underlined word “submerged” in Paragraph 5 most probably mean?

         A.Damaged by water.  B.Washed by water.

         C.Preserved by water.  D.Covered by water.

3.What is the topic discussed in the last paragraph?

         A.Advantages of walking on the Great Wall.

         B.Advantages of visiting the underwater Wall.

         C.The reasons why the Wall is deep under water.

         D.The reasons why the underwater Wall is protected.

4.What can we infer from the text?

        A.The underwater Wall will sink deeper year by year.

         B.Diving the Wall is popular with divers all over the world.

         C.Diving is a good way to visit the Wall without causing much damage.

         D.More and more tourists will come to visit the underwater Wall in China.

Gene technology to benefit people
Among all the fast growing science and technology, the research of human genes, or biological engineering as people call it, is drawing more and more attention now. Sometimes it is a hot topic discussed by people.
The greatest thing that gene technology can do is to cure serious diseases that doctors at present can almost do nothing with, such as cancer and heart disease. Every year, millions of people are murdered by these two killers. And to date, doctors have not found an effective way to cure them. But if the gene technology is applied, not only these two diseases can be cured completely, bringing happiness and more living days to the patients, but also the great amount of money people spend on curing their diseases can be saved, therefore it benefits the economy as well. In addition, human life span(壽命) can be prolonged.
Gene technology can help people to give birth to more healthy and clever children. Some families, with the English imperial(皇室) family being a good example, have hereditary(遺傳的) diseases. This means their children will for sure have the family disease, which is a great trouble for these families. In the past, doctors could do nothing about hereditary diseases. But gene technology can solve this problem perfectly. The scientist just need to find the wrong gene and correct it and a healthy child will be born.
Some people are worrying that the gene research can be used to manufacture human beings in large quantities. In the past few years, scientists have succeeded in cloning a sheep; therefore these people predict that human babies would soon be cloned. But I believe cloned babies will not come out in large quantities, for most couples in the world can have babies in very normal way. Of course, the governments must take care to control gene technology.
【小題1】 What does "these two killers" in the second paragraph refer to? 

A.Gene technology and another treatment of the two diseases.
B.The two murderers who killed the cloned baby
C.The two diseases of cancer and heart disease
D.Hereditary diseases and cancer
【小題2】What’s the main idea of the third paragraph?
A.How gene technology can be applied in the field of treating hereditary diseases.
B.Gene technology can be used to clone human babies.
C.Gene technology can help people to give birth of a baby.
D.Gene technology can help the English imperial family out
【小題3】In what way gene technology can help to treat hereditary diseases?
A.Using gene technology, people with hereditary diseases can have more living days.
B.Using gene technology, scientist finds the wrong gene and corrects it.
C.Using gene technology, human babies can be cloned.
D.Doctors can cure cancer and heart disease with the help of gene technology.
【小題4】 What is the main purpose of writing this passage?
A.Expressing the writer’s idea that gene technology will benefit people
B.Telling people the advantages of gene technology
C.Telling the readers that gene technology will not benefit people
D.Explaining that gene technology will also do harm to the humanity

Homeownership has let us down. For generations, Americans believed that owning a home was undoubtedly good. Our political leaders hammered home the point. Franklin Roosevelt held that a country of homeowners was “unconquerable.” Homeownership could even save babies, save children, save families and save America. A house with a lawn and a fence wasn’t just a nice place to live in or a risk-free investment; it was a way to shape a nation. No wonder leaders of all political types wanted to spend more than $100 billion a year on subsidies(補助)and tax breaks to encourage people to buy.
But the dark side of homeownership is now all too apparent: Indeed, easy lending stimulated(刺激)by the cult of homeownership may have triggered(引起)the financial crisis. Housing remains a drag on the economy. Existing-home sales in April dropped 27% from the previous month, worsening fears of a double-dip. And all that is just the obvious tale of a housing bubble and what happened when it popped. The real story is deeper and darker still.
For the better part of a century, politics, industry and culture lined up to create a fetish of the idea of buying a house. Homeownership has done plenty of good over the decades; it has provided stability to tens of millions of families. Yet by idealizing the act of buying a home, we have ignored the downsides. In the bubble years, lending standards slipped dramatically, allowing many Americans to put far too much of their income into paying for their housing. And we ignored longer-term phenomena too. Homeownership contributed to the hollowing out of cities and kept renters out of the best neighborhoods. It fed America’s overuse of energy and oil. It made it more difficult for those who had lost a job to find another. Perhaps worst of all, it helped us become casually self-deceiving: By telling ourselves that homeownership was a pathway to wealth and stable communities and better test scores, we avoided dealing with these frightening issues head-on.
Now, as the U.S. recovers from the biggest housing bust(破產)since the Great Depression, it is time to rethink how realistic our expectations of homeownership are—and how much money we want to spend chasing them. Many argue that homeownership should not be a goal pursued at all costs.
【小題1】Political leaders wanted to spend money encouraging people to buy houses because______.

A.owning a home was undoubtedly good
B.homeownership could shape a country
C.houses could save families and America
D.homeownership was unconquerable
【小題2】The underlined sentence in Para. 2 means ______.
A.homeownership has quite a lot of bad effects
B.there might be another housing breakdown in the U.S.
C.the existing-home sales will keep decreasing in the U.S.
D.the result of homeownership is much worse than it appears
【小題3】It can be inferred from Para. 3 that ______.
A.Americans choose to live out of urban areas
B.it is the way to wealth to have one’s own house
C.it is hard for Americans to get a home loan
D.homeownership has made many people out of work
【小題4】What is the author’s attitude towards homeownership?
A.Cautious.B.Ambiguous.C.Favorable.D.Optimistic.
