[单选题]Drunken driving, sometimes called America's socially accepted form of murder, has become a national epidemic. Every hour of every day about three Americans on average are killed hy drunken drivers, adding up an incredible 350,000 over the past decade. A drunken driver is usually defined as one with a 0.10 blood alcohol content or roughly three beers, glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American alcohol image and judges were lenient in most courts, but the drunken slaughter has recently caused so many well-publicized tragedies, especially involving young children, that public opinion is no longer so tolerant. Twenty states have raised the legal drinking age to 21, reversing a trend in the 1960s to reduce it to 18. After New Jersey lowered it to 18, the number of people killed by 18 to 20-year-old drivers more than doubled, so the state recently upped it back to 21.Reformers, however, fear raising the drinking age will have little effect unless accompanied by educational programs to help young people to develop"responsible attitudes" about drinking and teach them to resist peer pressure to drink. Tough new laws have led to increased arrests and in many areas already, to a marked decline in fatalities. Some states are also penalizing bars for serving customers too many drinks. As the fatalities continue to occur daily in every state, some Americans are even beginning to speak well of the 13 years' national prohibition of alcohol that began in 1919, which President Hoover called the"noble experiment". They forget that legal prohibition didn't stop drinking, but encouraged political corruption and organized crime. As with the booming drug trade generally, there is no easy solution. Which of the following four drivers can be defined as an illegal driver?
A.A sixteen-year-old boy who drank a glass of wine three hours ago.
B.An old lady who took four shots of whisky in yesterday's party.
C.A policeman who likes alcohol very much.
D.A pregnant woman who drank a beer an hour ago.

[简答题]

It is hard to predict how science is going to turn out, and if it is really good science it is impossible to predict. If the things to be found are actually new, they are by definition unknown in advance. You cannot make choices in this matter. (46) You either have science or you don’t, and if you have it you are obliged to accept the surprising and disturbing pieces of information, along with the neat and promptly useful bits.
The only solid piece of scientific truth about which I feel totally confident is that we are profoundly ignorant about nature. Indeed, I regard this as the major discovery of the past hundred years of biology. It is, in its way, an illuminating piece of news. (47) It would have amazed the brightest minds of the 18th century Enlightenment to be told by any of us how little we know and how bewildering the way ahead seems. (48) It is this sudden confrontation with the depth and scope of ignorance that’ represents the most
