C Since the earliest times,trees have always been very useful and important to man who made use of them in many ways for his daily life.Today trees continue to play a very important part in many ways.They provide man with fruits,fuel for burning,wood for building and furniture.You can imagine what would happen if there were no trees in the world in which we're living. In the tropics where it's very warm throughout the year,trees protect man from the heat of the hot sun.They are also very useful in protecting good and rich topsoil from being washed away,as there are many heavy rains there. Without trees and grass,heavy rains would wash away the rich surface soil which is so essential for agriculture.The result is that the land becomes useless and unproductive. There are many desert areas in the world,which used to be very rich and fertile areas.But people in ancient times cut down trees indiscriminately and no new trees were planted.When strong winds came,they blew away the rich surface soil and for this reason the land was ruined into useless deserts where nothing could grow. 64.From the passage,we know_________.

Do n’t get mad. He’s just telling you the truth. Teenagers in Britain and the US have a weapon against the older generation，especially parents and teachers. It’s a ring tone that many adults cannot hear. According to a recent report from the New York Times，in some Manhattan schools，students have begun using the technology. Cellphone use is usually forbidden in class. But using the high-pitched (频率) ring tone，students can successfully exchange phone messages without being found by their teachers. The technology relies on the fact that most adults gradually lose the ability to hear high-pitched sounds, It was developed in Britain but has recently spread to America by the Internet. However，the technology was originally aimed at annoying teenagers，not the other way around. Called the Mosquito，it was marketed last year by a Welsh security company. It is an ear-splitting 17-kilohertz buzzer (蜂鸣器) designed to help shopkeepers get rid of young people hanging around in front of their stores. Humans can hear sounds taking place in a frequency range between 200 and 20,000 hertz，as the research shows. But our hearing gradually becomes worse when we grow up. (责任编辑：admin) |
