In the US, poll after poll has shown a majority in favour of animal experimentation, even without statements about its value. Why is opinion in Britain so different？ I think that there are two reasons.
The first is the success of antivivisection campaigners in lampooning animal research as outdated, intentionally cruel, "bad" science, which achieves nothing. All drugs and procedures developed with the help of animal tests are said to be dangerous. The occasional failure of animal testing to identify a dangerous drug is developed as an argument for abandoning safety tests involving animals altogether--with no mention of the terrible human suffering that this would cause. They say that "alternative" methods already exist for all animal experiments, but the fact is that the law specifically forbids animal use if there is any alternative.
The second reason is that scientists and doctors have failed to oppose such misrepresentation. In the early 1990s, animal rights campaigning in the US was met with much more forthright defense, not only by the major scientific societies, funding agencies and medical organizations, but also by the US government.
To be positive, there are many encouraging features of the New Scientist poll. Interestingly, the public seems to employ the same kind of utilitarian philosophy that underpins the law in Britain--weighing potential benefits against the species involved (thus, monkeys are more "valuable" than mice) and the likelihood of suffering.
Clearly, people in Britain do not recognize the essential link between animal research and testing and the medical treatments that they receive. Only 18 percent of those who had taken (or had a close family member who had taken a drug prescribed for a serious illness realized that the drug had been tested on animals, as all drugs are. Obviously, a large majority of those surveyed believe that they can happily benefit from medical treatment without taking advantage of animal research. No wonder so many people oppose it when asked the straight yes/no question.
The views of the public must be respected. But this poll tells us that, while they are open to persuasion, their reaction is based on misunderstanding. The responsibility for providing honest evidence for the public lies not just with those who use animals in their research, but with other scientists who depend on that work. It lies with the doctors who benefit from animal research, with the pharmaceuticals and biotech industries, and the medical charities and funding age, les whose work would be crippled without it. But most of all, responsibility rests with government, which should cultivate serious and transparent debate between those of different opinion, and provide the public--especially young people--with the honest evidence they need and deserve.
In the first sentence of Paragraph 3, "such misrepresentation" refers to ______.
A．the idea that other methods can be substituted for animal research
B．the claim that animal experiment is intentionally cruel
C．the belief that all drugs developed with animal tests are dangerous
D．the fact that scientists and medical organizations support animal experimentation

听力原文：There are two factors which determine an individual's intelligence. The first is the sort of brain he is born with. Human brains differ considerably, me being more capable than others. But no matter how good a brain he has to begin with an individual will have a low order of intelligence unless he has opportunities to learn. So the second factor is what happens to the individual — the sort of environment in which he is.
The importance of environment in determining an individual's intelligence can be demonstrated by the case history of the identical twins, Peter and Mark. Being identical, the twins had identical brains at birth, end their growth processes were the same. When the twins were three months old, their parents died, and they were placed in separate homes. Peter was reared by parents of low intelligence in an isolated community with poor educational opportunities.
Mark, on the other hand, was raised in the home of rich parents who had been to college. He was read to as a child, sent to a good school, and given every opportunity to be stimulated intellectually. This environmental difference continued until the twins were in their late teens, when they were given tests to measure their intelligence. Peter's score was 85, well below the level he might have attained if reared under average conditions. Mark' s score was 125, twenty-five points above the average and fully forty points higher than his identical brother. Given equal opportunities, the twins would have tested at roughly the same level.
(38)
A．Children reared under average conditions possess average intelligence.
B．Lack of opportunity prevents the growth of intelligence.
C．An individual's intelligence is determined chiefly by his environment.
D．Changes of environment produce changes in the brain structure.

Rugby has the reputation of being the roughest sports in the world. Outside the British Isles, rugby is little known and, in fact, is often confused with soccer. But in England, as old sports saying serves to point out the differences between the two games: soccer is supposedly a gentlemen's game played by ruffians, whereas rugby is a ruffian's game played by gentlemen.
The game begins with a kick-off from one end of a 100-yard field. The receiving ruggers, as a rugby team is called, attempt to move the ball down the field, the opposing team attempts to stop the man with the ball.
The rules are quite simple. You cannot tackle anyone but the man who is carrying the ball, and once the ball carrier is tackled, he must give up the ball. Obviously, a good strategy for moving the ball. downfield is to carry it as far as possible, then pass the ball before being tackled.
If the ball carder can travel the length of the field, his team is awarded four points, and another two points are won by kicking the ball over the goalpost after the score. Penalties are equally simple, tackling a player who is not carrying the ball carries a ten-yard penalty. Much of rugby's reputation for roughness stems from the fact that the players wear no pads. To Americans accustomed to seeing professional foot-ball players in suits and helmets like armor, a rugby player's uniform. seems suicidally simple. Most ruggers wear a very thick jersey, heavy gymnasium shorts, heavy socks, rugby shoes, and a mouthpiece. Ruggers use other equipment or pads only when an injury requires protection. But even with this minimal equipment, the game is apparently not as brutal as it might seem. The players are quite satisfied with the lack of padding and helmets and actually think the game might be too rough if players used more equipment. "Human nature is not to hit as hard if no one is wearing pads," one rugger explains. Rugby games are played in two halves, each lasting forty minutes. Teams always meet to play two games consecutively, back-to-back. Again, playing a demanding physical sport like rugby for more than 160 minutes seems like an impossible task, but the ruggers love this idea. "It gives everyone on the team a chance to get into the game," they say. Rugby is slowly catching on in America. The sport is gaining an enthusiastic following among college teams and in independent ruggy "unions" organized on the British model. It has all the appeal of football, but it is simpler and requires much less costly equipment. Rugby is ready to be rediscovered.
The main purpose of this passage is to ______.
A．compare English and American sports
B．compare rugby to football
C．discuss the brutality of rugby
D．provide a brief introduction to rugby
