Ⅲ. 阅读理解

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. the problems with human cloning

B. the disadvantages of human cloning

C. the advantages of human cloning

D. the different ways human cloning is done

2. According to Dr. Richard Seed we can use cloning technology _______.

A. to make people look younger

B. to make people live longer

C. to cure people of many diseases

D. to produce more animals

3. From the passage we can infer that _______.

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

5. Treated with an organ cloned from his own stem cells, _______.

A. the patient is more likely to develop other diseases

B. the patient’s immune systems don’t reject the new organ

C. the patient will be free of rejection by his immune systems

D. the patient will suffer from Alzheimer’s disease

Ⅳ. 读写任务

阅读下面的短文，然后按照要求写一篇150词左右的英语短文。

The following story took place long ago in Israel. One day when government officials were using smoke to force the mice inside a hole to come out, they saw two mice, after all the others escaped, squeezing slowly out at the exit of the hole. The strange thing was that after they came out, they did not run away immediately. Instead, one chased after the other near the exit of the hole. It seemed that one was trying to bite the tail of the other.

Everyone was puzzled, so they stepped closer to take a look. They realized that one of the mice was blind and could not see anything, and the other one was trying to allow the blind mouse to bite on its tail so it could pull the blind one with it to escape.

After witnessing what happened, everyone was speechless and lost in thought. Then, one serious Rome official said:“I think the relationship between those two mice was that of emperor and minister. ”A smart Israel said：“I think husband and wife. ” A Chinese, who was accustomed to the firm tradition of loyalty to parents, said: “I think mother and son. ” And a pure Samaritan said. . .

Ⅳ. 【参考范文】

After seeing a mouse risked its life helping a blind mouse to escape, people made a lot of guesses at their relationship, thinking they might be emperor and minister, couple, or mother and son.

In my opinion, these two mice are most likely to be mother and son because I believe love from a mother is the most selfless and powerful emotion in the world. In such emergency, only a devoted mother has the extraordinary courage to save her son at any cost and protect her son against any harm. A mother can sacrifice anything for her son, even her life, not to mention, being bitten.

I can still remember the moving scene I saw on TV during the Wenchuan Earthquake. It’s reported that after several days of rescue, from inside a collapsed building came cries of a baby. Amazed how such a fragile baby can survive such a destructive catastrophe, people recorded the whole rescue process. It turned out that the baby’s mother, a weak woman, knelt down against a heavy wall with great power, creating a small shelter for her baby with her arms even after her death.

Love doesn’t necessarily mean romance, but we can easily see the unconditional love from a mother, whether it’s a bitten tail or broken arms.
