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.

I fell in love with the minister’s son in winter when I turned fourteen. He was not Chinese.For Christmas I prayed for the boy, Robert. When I found out that my parents had invited the minister’ s family over for Christmas Eve dinner, I cried in panic What would’ Robert think of our shabby Chinese Christmas What would he think of our noisy Chinese relatives who lacked proper American manners
On Christmas Eve, my mother created abundant Chinese food.And then they arrived--the minister’ s family and all my relatives.Robert greeted hello, and I pretended he was not worthy of existence.
Dinner threw me deeper into disappointment.My relatives licked(舔)the ends of their chopsticks and reached across the table.Robert and his family waited patiently for a large plate to be passed to them.My relatives murmured with pleasure when my mother brought out the whole steamed fish.Robert made a face.Then my father reached his chopsticks just below the fish eye and picked out the soft meat. "Amy, your favorite," he said, offering me the tender fish cheek.I wanted to disappear.
At the end of the meal, my father leaned back and burped(打嗝)loudly, thanking my mother for her fine cooking."It’s a police Chinese custom to show you are satisfied, "explained my father to our astonished guests.Robert was looking down at his plate with a reddish face.The minister managed to bring up a quiet burp.I was shocked into silence for the rest of the night.
After everyone had gone, my mother said to me, "You want to be the shame as American girls on the outside. "She handed me an early gift. It was a miniskirt. "But inside you must always be Chinese. You must be proud you are different. Your only shame is to have shame. "
It was not until years later that I was able to fully appreciate her lesson and the purpose behind her particular menu. For Christmas Eve that year, she had chosen excellent Chinese food.

Dinner threw me deeper into disappointment mainly because（）

A:My relatives licked the ends of their chopsticks B:My father reached his chopsticks to pick fish for me C:My father leaned back and burped loudly D:I childishly expected all of us to act in the same way as Americans at table

Passage 2
Flying over a desert area in an airplane,two scientists looked down with trained eyes at trees and bushes,After an hour's flight one of the scientists wrote in his book,“Look here for probable metal.”Scientists in another airplane,flying over a mountain area,sent a message to other scientists on the ground,“Gold possible.”Walking across hilly ground,four scientists reported.“The ground should be searched for metal.”From an airplane over a hilly wasteland a scientist sent there by radio one word:“Uranium.” None of the scientists had X ray eyes:they had on magic powers of looking down below the earth's surface.They were merely putting to use one of the newest methods of locating minerals in the ground,using trees and plants as signs that certain minerals may lie beneath the ground on which trees and plants are growing. This newest method of searchng for minerals is based on the fact that minerals deep in the earth may affect the kind of bushes and trees that grow on the surface. At Weston Bar Greek,a brook six thousand feet high in the mountains of British Columbia,Canada,a mineral search group gathered bags of tree seeds.Boxes were filled with small branches from the trees.Roots were dug and put into boxes.Each bag and box was carefully marked.In a scientific laboratory the parts of the forest trees were burned to ashes and tested.Each small part was examined to learn whether there were minerals in it. Study of the roots,branches,and seeds showed no silver.But there were small amounts of gold in the roots and a little less gold in the branches and seeds.The seeds growing nearest to the tree trunk had more gold than those growing on the ends of the branches.

The study of trees, branches and roots shows that （）.

A:larger amounts of gold in the branches than in the seeds B:smaller amounts of gold in the roots than in the branches C:less amounts of gold in the seeds growing on the ends of branches than seeds growing nearest to the tree trunk D:there was more gold in the branches than in the roots
