【题目】Among the most popular books being written today are those which are usually classified as science fiction. Hundreds of titles are published every year and are read by all kinds of people. Furthermore, some of the most successful films of recent years have been based on science fiction stories.

It is often thought that science fiction is a fairly new development in literature, but its ancestors can be found in books written hundreds of years ago. These books were often concerned with the presentation of some form of ideal society, a theme which is still often found in modern stories.

Most of the classics of science fiction, however, have been written within the last one hundred years. Books by writers such as Jules Verne and H. G. Wells, to mention just two well-known authors, have been translated in many languages. Modern science fiction writers don't write about men from Mars or space adventure stories. They are more interested in predicting the results of technical developments on society and the human mind, or in imagining future worlds which are a reflection of the world which we live in now. Because of this their writing has obvious political undertones.

In an age where science fact frequently over-takes science fiction, the writers may find it difficult to keep ahead of scientific advances. Those who are sufficiently clear-sighted to see the way we are going, however, may provide a valuable lesson on how to deal with the problems which society will inevitably face as it tries to master its new technology and come to terms with a continually changing view of the world.

【题目】There are many ways in which human cloning is expected to benefit mankind. Below is a list that is far from complete.

Dr. Richard Seed, one of the leading proponents (支持者) of human cloning technology, suggests that it may someday be possible to reverse the aging process because of what we learn from cloning. Scientists believe that they may be able to treat heart attack victims by cloning their healthy heart cells and injecting them into the areas of the heart that have been damaged. Heart disease is the number one killer in the United States and several other industrialized countries.

There has been a breakthrough with human stem cells. Embryonic (胚胎的) stem cells can be grown to produce organs to repair or replace damaged ones. Skin for burn victims, brain cells for the brain damaged, hearts, lungs, livers, and kidneys could be produced. By combining this technology with human cloning technology it may be possible to produce needed organs for suffering people that will be free of rejection by their immune systems. Conditions such as Alzheimer’s disease, Parkinson’s disease, diabetes, heart failure, and other problems may be made curable if human cloning and its technology are not banned.

Despite getting a fair amount of publicity in the news current treatments for infertility (不生育), in terms of percentages, are not very successful. One estimate is that current infertility treatments are less than 10 percent successful. Couples go through physically and emotionally painful procedures for a small chance of having children. Many couples run out of time and money without successfully having children. Human cloning could make it possible for more infertile couples to have children than ever before.

【1】 The passage mainly deals with _______.

A. cloning has already been used to treat heart diseases

B. we can treat a man’s heart disease by cloning others’hearts

C. most people in industrialized countries suffer from heart diseases

D. more people die of heart diseases than of other diseases in America

【4】What would be the best headline for the last paragraph?

A. With Cloning, Infertile Couples Could Have Children

B. Treatment of Infertility Is Not Successful

C. Physically and Emotionally Pain of Infertile Couples

D. The News Is Not Telling the Truth
