完形填空(共20小题;每小题1.5分,共30分) If you think you are sick, you are sick no matter what 41 says. 42 , if you believe in your doctor, and if he tells that you are going to feel better, you probably will. The 43 of the mind on the body does exist and sometimes can be powerful. It exists whether one is 44 of it or not. Take the 45 of Mrs. Green, for example. She was unable to get to sleep at night and was too tired during the day to do some simple things that she 46 enjoy doing. She had headaches more often which 47 her from reading or watching TV. The more she thought about her conditions, 48 she felt. At last she went to 49 her doctor, whom she had known for years. The doctor listened to her and gave her a very 50 examination. Then he said to her, “ There is nothing 51 wrong with you physically, but I accept the fact 52 you don’t feel well. I’m going to give you some pills that should help. I want you to 53 one after dinner and one half an hour 54 you go to bed tonight. Call me tomorrow and tell me 55 you feel. 56 Mrs. Green telephoned, “Doctor, I had the first 57 night’s sleep in two months. What is in this pills 58 ?” The doctor said, “It is an old formula(配方) I have 59 for years. Just 60 taking them for a week.” Turning to the nurse, he said, “It’s wonderful what a little baking soda(苏打) can do.”

In the next century we’ll be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. When Dr. Frankenstein made his monster, he wrestled with the moral issue of whether he should allow it to reproduce, "Had I the right, for my own benefit, to inflict the curse upon everlasting generations" Will such questions require us to develop new moral philosophies
Probably not. Instead, we’ll reach again for a time-tested moral concept, one sometimes called the Golden Rule and which Kant, the millennium’s most prudent moralist, conjured up into a categorical imperative: Do unto others as you would have them do unto you; treat each person as an individual rather than as a means to some end.
Under this moral precept we should recoil at human cloning, because it inevitably entails using humans as means to other humans’ ends and valuing them as copies of others we loved or as collections of body parts, not as individuals in their own right. We should also draw a line, however fuzzy, that would permit using genetic engineering to cure diseases and disabilities but not to change the personal attributes that make someone an individual (IQ, physical appearance, gender and sexuality).
The biotech age will also give us more reason to guard our personal privacy. Aldous Huxley in Brave New World, got it wrong: rather than centralizing power in the hands of the state, DNA technology has empowered individuals and families. But the state will have an important role, making sure that no one, including insurance companies, can look at our genetic data without our permission or use it to discriminate against us.
Then we can get ready for the breakthroughs that could come at the end of the next century and the technology is comparable to mapping our genes: plotting the 10 billion or more neurons of our brain. With that information we might someday be able to create artificial intelligences that think and experience consciousness in ways that are indistinguishable from a human brain. Eventually we might be able to replicate our own minds in a "dry-ware" machine, so that we could live on without the "wet-ware" of a biological brain and body. The 20th century’s revolution in infotechnology will thereby merge with the 21st century’s revolution in biotechnology. But this is science fiction. Let’s turn the page now and get back to real science.
Judged from the information in the last paragraph, we can predict that the author is likely to write which of the following in the next section()
A. The reflection upon biotechnological morality
B. The offensive invasion of our personal privacy
C. The inevitable change of IQs for our descendants
D. The present state of biotechnological research
