SECTION C NEWS BROADCAST

Directions: In this section, you will hear several news items. Listen to them carefully and then answer the questions that follow.

听力原文： Thai researchers have created a new strain of rice with 12 times as much protein as regular varieties, and aim to promote it to the world. Scientists at Kasetsart University told the VOA reporter yesterday that the new strain was the most nutritious of the rice strains developed so far. And it was created not by high-tech genetic modifications, but through natural method, Khao Hom Nil, or black fragrant rice, sprang from a variety brought from China to the University's Agriculture and Biotechnology Center. Scientists there discovered certain strain of the plant was unusually rich in protein.

According to the news, the new type of rice was created by ______.

A．high-tech genetic modification

B．Thai researchers

C．the help of some experts from China

根据以下内容回答题：

It is Dredicted that there will be four scientific breakthroughs in the 21 st centruy． We wiuknow where we came from．Since the l920s，scientists have known the universe is expanding，which means it must have started at a definite time in the past．They even have de-veloped theories that give a detailed picture of the universe from the time it was a fraction of a second old to the present．Over the next couple of decades，these theories will be improved by data from powerful new telescopes． We will find out the genetic code and conquer cancer．In l9th century operas，when the heroine coughs in the first act，the audience knows"she will die of tuberculosis in the third act．

But thanks to 20th century science，the once deadly disease now means nothing more serious than taking some pills．As scientists learn more about the genetic code and the way cells work，many serious desease——cancer．will become less threatening． We will live longer，probably up to 1 20 years．If the normal aging process is basically a fierce．invisible contest in our ceus——a contest between damage to our DNA and our ceils’abili-ty to repair that damage，gre{at progress around．But before we push scientists to do more，we should consider：do we really want to live in a world where no one grows old？We will haye a hrain road map．This is the real final frontier of the 21 st century．The brain is the most complex system we know．It contains about l00 billion nerve cells，each con-nected to as many as l000 0thers．Early in the 21 st century，progress in science will make it Dossible to produce detailed images of the nerve cells in operation．We will be able to say with certainty which ones are working when you read or think about a word．

Jadging from the second paragraph，the writer thinks of present theories about the uinverse as __________．

A.perfect

B.imperfect

C.groundless

D.complicated

ities 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.

Dr. Frankenstein's remarks are mentioned in the text ______.

A．to give an episode of the DNA technological breakthroughs.

B．to highlight the inevitability of a means to some evil ends.

C．to show how he created a new form. of life a thousand years ago.

D．to introduce the topic of moral philosophies concerning biotechnology.
