1. She couldn't have come at a better time. 2. She has been a widow only six months. 3. I believe the speech was needlessly stubborn. 4. The Macedonian argument has a Greek dimension too. 5. The Englishman feels no less deeply than any other nationality. 6. From a physical standpoint, there ought to be as many colours as there are different wave lengths. 7. But the next century we'll be able to alter our DNA radically, encoding our visions and vanities while concocting new life-forms. 8. As a human being, we should demonstrate our intellectual and moral superiority by respecting others for who they are -- instead of rejecting them for who/what they are not.

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 tech nology 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 importance of a means to some everlasting ends.
C.to show how he created a new form. of life a thousand years ago.
D.to introduce the topic of moral philosophies incurred in biotechnology.

根据下面材料,回答题。
It is predicted that there will be 5 scientific breakthroughs in the 21st century. We"ll know where we came from. Why does the universe exist? To put it another way, why is there something instead of nothing? Since the 1920s, scientists have known the universe is expanding, which means it must have started at a definite time in the past. They even have developed theories that give a detailed picture of the evolution 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 refined by data from extraordinary powerful new telescope. We will have a better understanding of how matter behaves at the unfathomably high temperatures and pressures of the early universe.
We"ll crack the genetic code and conquer cancer. In 19th century operas, when the heroine coughs in the first act, the audience knows she will die of tuberculosis in Act 3. But thanks to 20th century antibiotics, the once dreaded, once incurable disease now can mean nothing more serious than taking some pills. As scientists learn more about the genetic code and the way cells work at the molecular level, many serious diseases——cancer, for one- will become less threatening. Using manufactured "therapeutic" viruses, doctors will be able to replace cancer causing damaged DNA
with healthy genes, probably administered by a pill or injection.
We"ll live longer (120 years?) If the normal aging process is basically a furious, invisible contest in our cells- a contest between damage to our DNA and our cells ability to repair that damage- then 21st century strides in genetic medicine may let us control and even reverse the process. But before we push scientists to do more, consider: Do we really want to live in a world where no one grows old and few children are born because the planet can hold only so many people?
Where would new ideas come from? What would we do with all that extra time?
We"ll "manage" Earth. In the next millennium, well stop talking about the weather but will do something about it. Well gradually learn how to predict the effects of human activity on the Earth,its climate and its ecosystems. And with that knowledge will come an increasing willingness to use it to manage the workings of our planet.
We"ll have "a brain road map". This is the real "final frontier" of the 21st century: The brain is the most complex system we know. It contains about 100 billion neurons (roughly the number of stars in the Milky Way), each connected to as many as 1,000 others. Early in the next century, we will use advanced forms of magnetic resonance imaging to produce detailed maps of the neurons in operation. We"ll be able to say with certainty which ones are working when you read a word, when you say a word, when you think about a word, and so on.
The sentence "In 19th century operas, when the heroine coughs in the first act, the audience knows she will die of tuberculosis in Act 3" means__________. 查看材料
A.there was not antibiotics at that time
B.tuberculosis was a terrible disease that couldn"t be cured during 19th century
C.the health of the heroine was very poor
D.this was a common situation in the 19th century operas
