Presenter: Good evening and welcome to Issue for Today. Our topic tonight is experiment on animals and to start the discussion we have a strongly argued appeal from Jeff Sachs of the animal’s rights organization Animal Aid. Now Jeff, what’s all the fuss about After all, 85 percent of doctors support experiments on animals. Jeff: This is first and foremost a moral question. What kind of people are we As humans, we live in a society which protects the rights of the weak. We take care of the sick, the old and the disabled and punish those who are violent to others. But we also have a darker, cruel side. I believe that we experiment on animals because they are powerless to stop us, and we count their pain as unimportant when measured against our own interests. We live unhealthy lives and make animals suffer in the search for cures for our illnesses. We even see the production of a new lipstick as a good enough reason to inflict pain on animals. It’s not that we th

W: It’s well-known science fiction plot to freeze a body and bring it back to life years later.
However, this may no longer be so far from the truth. Joining us from our Cardiff studio is Professor Andrew Morgan, who’s been doing some research into this subject. Professor Morgan.

And, what I’ve been working on over the past two years is the particular process that enables them to do this.
W: What have you actually discovered
M: I think it’s a particular chemical in the animals’ bodies which begins to work under certain circumstances. And I’m now experimenting with this chemical to see if I can get other animals that wouldn’t normally be able to freeze themselves to be able to do this.

Malls are popular places for Americans to go. Some people spend so much time at malls that they are called "mall rats". Mall rats shop until they drop in the hundreds of stores under one rood.
People like malls for many reasons. They feel safe because malls have police stations of private security guards. Parking is usually free, and the weather inside is always fine. The newest malls have beautiful rest areas with waterfalls and large green trees.
The largest mall in the United States is the Mall of America in Minnesota. It covers 4.2 mil- lion square feet. It has 350 stores, eight night clubs, and a seven-acre park! There are park- ing spaces for 2,750 cars. About 750,000 people shop there every week.
The first indoor mall in the United States was built in 1965 in Edina, Minnesota. People like doing all their shopping in one place. More malls were built around the country. Now, malls are like town centers where people come to do many things, th

The history of English is conventionally, if perhaps too neatly, divided into three periods usually called Old (or Anglo-Saxon)English, Middle English, and Modern English. The earliest period begins with the migration of certain Germanic tribes from the continent to Britain in the fifth century A. D, though no records of their language survive from before the seventh century, and it continues until the end of the seventh century or a hit later. By that time, Latin, Old Norse(the language of the Viking invaders), and especially the Anglo-Nor-man French of the dominant class after the Norman Conquest in 1066 had begun to have a substantial impact on the vocabulary, and the well-developed inflectional (词尾变化的) system that typifies the grammar of Old English had begun to break down.
The period of Middle English extends roughly from the twelfth century through the fifteenth. The influence of French(and Latin, often by way of French)upon the vocabulary continued throughout the p

Whether work should be placed among the causes of happiness or among the causes of unhappiness may perhaps be regarded as a doubtful question. There is certainly much work which is exceedingly weary and an excess of work is always very painful. I think, however, that, provided work is not excessive in amount, even the dullest work is to most people less painful then idleness. There are in work all grades, from mere relief of tedium up to the profoundest delights, according to the nature of the work and the abilities of the worker. Most of the work that most people have to do is not in itself interesting, but even such work has certain great advantages. To begin with, it fills a good many hours of the day without the need of deciding what one shall do. Most people, when they are left free to fill their own time according to their own choice, are at a loss to think of anything sufficiently pleasant to be worth doing. And whatever they decide, they are troubled by the feeling that s
A. Work can keep people busy as if they were poor.
B. Work is a cause of the greatest delight of life.
C. Work is very tiresome, especially when too excessive.
D. Work can at least give relief from boredom. -

What is it about Paris For the last two centuries it has been the single most visited city in the world. Tourists still go for the art and the food, even if they have to brave the disdain of ticket-takers and waiters. Revolutionaries on the run, artists in search of the galleries and writers looking for the license to explore their inner selves went looking for people like themselves and created their own fields filled with experimentation and constant arguments. Would worldwide communist revolution have been conceivable without the Paris that was home to Marx, Lenin and Ho Chi Minh Would Impressionism or Cubism have become "isms" without Paris as a place to work and as a subject to paint How Paris came to be, for such a long time, "capital of the world"
The answer lies in the city’s "myths" according to the distinguished Harvard historian Patrice Higonnet in "Paris: Capital of the World. " In his book, Paris came to stand for

[简答题]American and Japanese researchers are developing a smart car that will help drivers avoid accidents by predicting when they are about to make a dangerous move.
The smart car of the future will be able to tell if drivers are going to turn, change lanes, speed up, slow down or pass another car.
If the driver’s intended action could lead to an accident, the car will activate a warning system or override the move.
(61)"By shifting the emphasis of car safety away from design of the vehicle itself and looking more toward the driver’s behavior, the developers believe that they can start to build cars that adapt to suit people’s needs," New Scientist magazine said.
Alex Pentland of the Massachusetts Institute of Technology collaborated on the project with Andrew Liu who works for the Japanese carmaker Nissan.
(62) Tests of their smart car using a driving simulator have shown that it is 95 percent accurate in predicting a driver’s move 12 seconds in

Every second in the United States alone, more than 250 animals are slaughtered for food, adding up to more than 8 billion animals each year. Reducing the amount of meat in one’s diet is nutritionally, environmentally, and ethically beneficial.
People who eat meat usually have weaker immune systems compared to those of vegetarians. Meat has been directly linked to diabetes, obesity, arthritis, and many other illnesses. Furthermore, meat-eaters are at a higher risk for diseases, including cancer, and they are more likely to die from these diseases. Critics say that a meatless diet does not provide enough nutrients, especially protein and iron. Actually, according to "A Teen’s Guide to Going Vegetarian", by Judy Krizmanic, protein is found in almost every food, and iron appears in many vegetables. Getting enough nutrients in a meat-reduced diet should not be difficult. A 1988 study found that some of the highest pesticide residues appear in meat and egg
A. They feel that eating animals is unethical.
B. There are fewer livestock available due to the environmental pollution.
C. The consumption of meat will lead to financial problem.

Every culture attempts to create a "universe of discourse" for its members, a way in which people can interpret their experience and convey it to one another. Without a common system of codifying sensations, life would be absurd and all efforts to share meanings would be doomed to failure. This universe of discourse--one of the most precious of all cultural legacies-is transmitted to each generation in part consciously and in part unconsciously. Parents and teachers give explicit instruction in it by praising or criticizing certain ways of dressing. of thinking, of gesturing, of responding to the acts of others. But the most significant aspects of any cultural code may be conveyed implicitly, not by rule or lesson but through modeling behavior. He child is surrounded by others who, through the mere consistency of their actions as males and females, mothers and fathers, salesclerks and policemen, display what is appropriate behavior. Thus the grammar of any culture is se
