小学生10分钟应用题系列答案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(寿命) 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(遗传的) 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.
【小题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 |

| C．Gene technology can help people to give birth of a baby. |
| D．Gene technology can help the English imperial family out |
| 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. |
| 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（补助）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（破产）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.

| A．Americans choose to live out of urban areas |
