In the next century we'll be able to alter our DNA radically, encoding our visions and van

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.

What will the next decade bring, as we move into a new millennium？ That’s getting hard
er and harder to predict. Change is coming so fast that some of the most important technologies of the 21st century may now be just a sketch on the drawing board or glimmer in the mind of genius. Then again, the transcendent technologies may be right under our noses on the verge of having as great an impact as the car or telephone.

In the nineteenth century, the invention of the telegraph made it possible to send noise
s, signals, and even music over wires from one place to another. However, the human voice 36 this way. Many inventors tried to find a way to send a voice over wires, and in 1876 some of their efforts were awarded with success.

Two American inventors, Alexander Graham Bell and Elisa Gray, succeeded at almost the same time. The United States Supreme Court finally had to decide which of the two was the first inventor of the telephone. The Court decided 37 Bell’s favor.

Born in Edinburgh, Scotland, Bell grew up in a family that was very interested in teaching people to speak. His grandfather had been an actor who left the theatre to teach elocution(演讲技巧); his father was a teacher 38 deaf-mutes learn how to speak.

However, probably none of the later inventions gave Bell the same feeling of success __39_ he had on the day when he spilled some acid from his batteries. It was after he had worked for months to find ways to send something more than metallic twangs(金属砰弦声)over the wires. Thinking Watson, __40__, was in the next room, Bell called, "Mr. Watson, come here. I want you." Watson was not in the next room. He was down in his laboratory, next to the receiver. To Watson's surprise, he heard the words perfectly. He ran to tell Bell the news: the wires had carried Bell's voice perfectly.

Americans are getting ready for the biggest soccer event in the world. For the first t

ime the world cup soccer competition will be held in the United States. While millions play the game around the world, soccer or football has only recently become popular here. It is only in the last 30 years that large numbers of young Americans became interested in soccer. Now it is the fastest growing sport in the country. A recent study found that almost 18 million young boys and girls play soccer in the United States.

The study also found that soccer is beginning to replace more traditional games like American football as the most popular sport among students. And so, when the world cup begins next week, more than one million Americans are expected to go and see the teams play. Organizers say this year’s world cup will be the biggest ever. All the seats at most of the 52 games have already been sold.

Soccer has been played in the United States for a little more than one hundred years. But how did the sport come to this country？ And how long has it existed in other parts of the world？ No one knows exactly where the idea for soccer came from, or when people began playing the game. Some scientists say there is evidence that ball games using the feet were played thousands of years ago. There is evidence that ancient Greeks and Romans and native American Indians all played games sim­ilar to soccer.

Most experts agree that Britain is the birthplace of modem soccer. They also agree that the British spread the game around the world. Unlike the game today, which uses balls of man-made material or leather, early soccer balls were often made of animal stomachs. The rules of early soccer games also differed from those we have today.

1.Which of the following statements is NOT true according to the text？()

A.Americans were preparing for the world cup when the author wrote this article

B.More younger Americans became interested in soccer in the last 30 years

C.Soccer is the fastest developing sport in the world

D.The article was written before the world cup held in the United States

2.Which was the most popular sport as a traditional game among students？()

A.Basketball

B.American football

C.Soccer

D.Tennis

3.For how long has soccer been played in the United States？()

A.About a hundred years

B.About fifty years

C.Only recently

D.About thirty years

4.What is the author going to state in the next paragraph？()

A.There have been attempts to start a professional soccer organization in the U.S

B.In the 12th century soccer games in Britain often involved whole towns

C.Professional soccer grew quickly in Europe

D.Experts believed that the United States would win

第7题
Some expressions describe people who are important or who at least think they are. One suc
h expression is "big wig". In the 17th century, important men in Europe began to wear false hair called wigs. As years passed, wigs began to get bigger. The size of a man's wig depended on how important he was.

The more important he was or thought he was, the bigger the wig he wore. Some wigs were so large that they covered the man's shoulders or back. Today the expression "big wig" is used to make fun of a person who feels important. People never tell someone he is a big wig. They only use the expression behind his back. "Big wheel" is another way to describe an important person. A big wheel may be the head of a company, a political leader, a famous movie star. They are big wheels because they are powerful. What they do affects many people. Big wheel gives the orders and other people carry them out.

As in many machines, a big wheel makes the little wheel turn. "Big wheel" became a popular expression after World War Ⅱ. It probably comes from an expression used for many Years by people who fit parts of the cars and trucks. They said a person whirled a big wheel if he was important or had influence.

The top of something is the highest part of something. So it is not surprising that top is part of another expression that describes an important person. The expression is "top banana". A top banana is the leading person in a comedy show.

The funniest comedian is called the "top banana". The next is second banana, and so on. Why a "banana"？ A comedy act in earlier days often included the part where one of the comedians would hit others over the head with a soft object. The object was shaped like the yellow food — the banana. "Top banana" is still used mainly in show business. Yet the expression can also be used to describe a top person in any area,

A "kingpin" is another word for an important person. The expression comes from the game of bowling. The kingpin is the No. one pin. If it is hit correctly by the bowling ball, the kingpin will make all the other nine pins fall. And that is the object of the game. So the most important person in a project or business is the kingpin. If the kingpin is removed, the project or business is likely to fail. Kingpin is often used to describe an important criminal or the leader of a criminal gang. A newspaper may report, for example, that the police have arrested the suspected kingpin of a car stealing operation.

This passage is mainly about______.

A．important people

B．how to describe important people

C．important expressions

D．expressions for important people
