Drunken driving –sometimes called America’s socially accepted form of murder—has become a national epidemic (流行病). Every hour of every day about three Americans on average are killed by drunken drivers，adding up to an incredible 250,000 over the past ten years. A drunken driver is usually referred to as one with 0.10-blood alcohol content or roughly three beer glasses of wine or shots of whisky drunk within two hours. Heavy drinking used to be an acceptable part of the American manly image and judges were lenient in most courts，but the drunken killing has recently caused so many well-publicized tragedies，especially concerning 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 18-20 years 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.

    Though new laws have led to increased arrests and tests in many areas already，to a marked drop in accidents，some states are also punishing bars for serving customers too many drinks. A bar in Massachusetts was fined for serving six or more double brandies to a customer who was ‘obviously drunk’ and later drove off the road，killing a 9-year-old boy.

As the accidents 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 forgot 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.

　　Trees are useful to man in three very important ways: they provide him with wood and other products, they give him shade, and they help to prevent drought and floods.

　　Unfortunately, in many parts of the world man has not realized that the third of these services is the most important. In his eagerness to draw quick profit from the trees, he has cut them down in large numbers, only to find that without them he has lost the best friends he had.

　　Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to gain itself an empire. It gained the empire but, without its trees, its soil became hard and poor. When the empire fell to pieces, the country found itself faced by floods and starvation.

　　Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by making charcoal or selling wood to the townsman. He is usually too lazy or too careless to plant and look after trees. So unless the government has a good system of control, or can educate the people, the forests will slowly disappear.

　　This does not only mean that the villagers? sons and grandsons have fewer trees. The results are even more serious. For where there are trees their roots break the soil up—allowing the rain to sink in and also hold the soil, thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert.

Let children learn to judge their own work.1.if corrected too much， he will stop talking. He notices a thousand times a day the difference between the languages he uses and the language those around him use.
