题目内容
Critics of cloning often repeat the question related to the controversial(有争议的) science “Just because we can, does it mean we should?” The closer we come to being able to clone a human, the hotter the debate over it grows. For all the good things cloning may achieve, opponents say that it will do just as much harm. Another question is how to governing cloning process.
There is federal official law banning cloning in the United States, but several states have passed their own laws to ban the practice. The US Food and Drugs Administration(FDA), has also said that anyone in the United States attempting human cloning must first get its permission. In Japan, human cloning is a crime that is punished by up to 10 years in prison.
While laws are to ban cloning at this time, some scientists believe that the technology is not ready to be tested on humans. Ian Wilmut, one of the co-creators of Dolly, has even said that human cloning projects would be an irresponsible crime. Cloning technology is still in its early stages, and nearly 98% percent of cloning efforts end in failure. The embryos are either not suitable for implanting into the uterus(子宫) or they die shortly after birth.
The clones that do survive end up suffering from deadly or problematic genetic abnormalities(畸形). Some clones have been born with faulty heart, lung problems and blood vessel problems. One of the most famous cases was a cloned sheep that was born with but malformed arteries(畸形动脉) leading to the lungs.
Opponents of cloning will point out that we can enthanize(安乐死) these faulty clones of other animals, but they ask what if a human clone is born with these same problems. Advocates of cloning respond that it is now easier to pick out faulty embryos even before they are implanted into the mother. The debate over human cloning is just beginning, but as science advances, it could be the biggest moral dilemma of the 21st century.
68. Which word in the text is the opposite of the underlined word “opponents”?
A. critics B. advocates C. scientists D. co-creators
69. The writer writes this passage mainly to ________________.
A. support passing laws to ban human cloning
B. list problems with human cloning
C. introduce critics’ ideas about human cloning
D. state the debate over human cloning
70. Which of the following will Ian Wilmut probably NOT agree with?
A. Cloning technology is in its early stages.
B. Human cloning should be made illegal.
C. Very few cloning efforts are successful.
D. Cloning technology is ready to be tested on humans

Waste to Energy—JUST BURN IT!
WHY BURN WASTE?
Waste-to-energy plants generate (产生) enough electricity to supply 2.4 million households in the US. But, providing electricity is not the major advantage of waste-to-energy plants. In fact, it costs more to generate electricity at a waste-to-energy plant than it does at a coal, nuclear, or hydropower plant.
The major advantage of burning waste is that it considerably reduces the amount of trash going to landfills. The average American produces more than 1,600 pounds of waste a year. If all this waste were landfilled, it would take more than two cubic yards of landfill space. That’s the volume of a box three feet long, three feet wide, and six feet high. If that waste were burned, the ashes would fit into a box three feet long, three feet wide, but only nine inches high!
Some communities in the Northeast may be running out of land for new landfills. And, since most people don’t want landfills in their backyards, it has become more difficult to obtain permits to build new landfills. Taking the country as a whole, the United States has plenty of open space, of course, but it is expensive to transport garbage a long distance to put it into a landfill.
TO BURN OR NOT TO BURN?
Some people are concerned that burning garbage may harm the environment. Like coal plants, waste-to-energy plants produce air pollution when the fuel is burned to produce steam or electricity. Burning garbage releases the chemicals and substances found in the waste. Some chemicals can be a threat to people, the environment, or both, if they are not properly controlled.
Some critics of waste-to-energy plants are afraid that burning waste will hamper (妨碍，阻碍) recycling programs. If everyone sends their trash to a waste-to-energy plant, they say, there will be little motive to recycle. Several states have considered or are considering banning waste-to-energy plants unless recycling programs are in place. Massachusetts, New Jersey, and New York City have delayed new waste-to-energy plants, hoping to increase the level of recycling first.
So, what’s the real story? Can recycling and burning waste coexist? At first glance, recycling and waste-to-energy seem to be at odds (不一致), but they can actually complement (弥补) each other. That’s because it makes good sense to recycle some materials, and better sense to burn others.
Let’s look at aluminum, for example. Aluminum mineral is so expensive to mine that recycling aluminum more than pays for itself. Burning it produces no energy. So clearly, aluminum is valuable to recycle and not useful to burn.
Paper, on the other hand, can either be burned or recycled—it all depends on the price the used paper will bring.
Plastics are another matter. Because plastics are made from petroleum and natural gas, they are excellent sources of energy for waste-to-energy plants. This is especially true since plastics are not as easy to recycle as steel, aluminum, or paper. Plastics almost always have to be hand sorted and making a product from recycled plastics may cost more than making it from new materials.
To burn or not to burn is not really the question. We should use both recycling and waste-to-energy as alternatives to landfilling.

What is great art? On the one hand, we can all see that great art is old art which is called great. But how do we know which art of our own times is great, and which will be forgotten? And who decides?
These are important questions, for the great art of the past often was not considered great during its own time. When Shakespeare and Charles Dickens were writing, for example, most critics considered them as hack (平庸的) writers with little or no literary ability.
Similarly, Van Gogh and many of the other Impressionist painters of the late nineteenth century were not allowed to participate in events involving what were thought to be the "real" painters of the time, and often they were very poor. Yet today their paintings often sell for millions of dollars, while those so-called "real" painters are now barely remembered.
So what makes great art? Can, for example, rock music be great art? Music videos? Cartoons and comics? Those who call themselves critics of the fine arts often have been the last to recognize great art in the past, and we can probably expect this to be the situation today.
Critics often don’t recognize great art because they tend to be prejudiced against what is popular. Popular works, whether they are novels, movies, or comics, are usually considered to be produced for the sake of money only, and not for the sake of art.
But popularity, it seems to me, is one of the three signs that a present-day work of art may come to be thought of as great. The other two are that it is groundbreaking, and that it is inherently (内在的) beautiful.
Many works have one or even two of these qualities of being popular, unusual, and beautiful. But having all the three often will mean that a work of art will someday be seen to be great, though it may take a good spoonful of time, such as a century or two, to know for sure.

Concern with money, and then more money, in order to buy the conveniences and luxuries of modern life, has brought great changes to the lives of most Frenchmen. More people are working harder than ever before in France. In the cities the traditional leisurely midday meal is disappearing. Offices, shops, and factories are discovering the great efficiency of a short lunch hour in company lunch rooms. In almost all lines of work emphasis now falls on ever increasing output. Thus the “typical” Frenchman produces more, earns more, and buys more consumer goods than his counterpart of only a generation ago. He gains in creature comfort and ease of life. What he loses to some extent is his sense of personal uniqueness, or individuality.
Some say that France has been Americanized. This is because the United States is a world symbol of the technological society and its consumer products. The so called Americanization of France has its critics. They fear that “assembly line life” will lead to the disappearance of the pleasures of the more graceful and leisurely (but less productive) old French style. What will happen, they ask, to taste, elegance, and the cultivation of the good things in life to joy in the smell of a freshly picked apple, a stroll by the river, or just happy hours of conversation in a local café?
Since the late 1950s life in France has indeed taken on qualities of rush, tension, and the pursuit of material gain. Some of the strongest critics of the new way of life are the young, especially university students. They are concerned with the future, and they fear that France is threatened by the triumph of this competitive, goods-oriented culture. Occasionally, they have reacted against the trend with considerable violence.
In spite of the critics, however, countless Frenchmen are committed to keeping France in the forefront of the modern economic world. They find that the present life brings more rewards, conveniences, and pleasures than that of the past. They believe that a modern, industrial France is preferable to the old.
1.Which of the following is a feature of the old French way of life?
|
A．Leisure, elegance, and efficiency |

A．Many of them prefer the modern life style. |
|
B．They actually enjoy working at the assembly line. |
|
C．They are more concerned with money than before. |
|
D．They are more competitive than the old generation. |
3.The passage suggests that _________.
|
A．in pursuing material gains the French are suffering losses elsewhere |
|
B．it’s now unlikely to see a Frenchman enjoying a stroll by the river |
|
C．the French are fed up with the smell of freshly picked apples |
|
D．great changes have occurred in the life style of all Frenchmen |
4.Which of the following is true about the critics?
|
A．Critics are greater in number than people enjoying the new way of life. |
|
B．Students critics are greater in number than critics in other fields. |
|
C．Students critics have, on occasion, resorted to violent means against the trend. |
|
D．Critics are concerned solely with the present and not the future. |

|
B．Criticism of the New Life Style |
|
C．The Americanization of France |
