听力原文： Earthquakes are something that most people fear. There are some places that have few or no earthquakes. Most places in the world, however, have them regularly. Some places, like Iran and Japan, have them frequently. Countries that have a lot of earthquakes are usually quite mountainous.
The most talked about earthquake in the United State was in San Francisco in 1906. Over 500 people died in it. The strongest one in North America was in 1964. It happened in Alaska.
Strong earthquakes are not always the ones that kill the most people. In 1755 one of the strongest earthquakes ever recorded was felt in Portugal. Around 20,000 people died.
In 1923 a very powerful earthquake hit the Tokyo-Yokohama area of Japan. 140, 000 people died. Most of them died in fires which followed the earthquake.
One of the worst earthquake ever was in China in 1976. It killed over 240,000 people. The worst earthquake ever reported was also in China. 830, 000 people were killed in this quake which happened in 1556.
Earthquakes are not the only acts of nature which people fear. Flood and tidal waves also cause people to be afraid. So do bad storms like typhoons and cyclones. Sometimes these things caused lots of deaths. In 1970 a cyclone and tidal wave killed over 200,000 in Pakistan.
These kinds of things make people afraid and they are very dangerous. But why they probably do not worry people is that we often know they are coming, we have some warning. Someday we may be able to know an earthquake is coming. So far, however, no sure way is known to predict an earthquake. When one comes it is a surprise. People cannot prepare for it, so thousands of people still die in earthquakes like the one in China in 1976.
In what kind of countries are earthquakes likely to occur？

W: What's the main feature of drug addiction？
M: Drug addiction is marked by a compulsive craving for a substance.
W: Is it true that there is no escape once you fall in the hand of drugs？
M: Not exactly. Successful treatment methods include psychotherapy, and detoxification programs— medically supervised programs that gradually wean an individual from a drug over a period of days or weeks. Detoxification and psychotherapy are often used together.
W: Why are so many young people go in for drags？
M: Most of the young people go astray just out of curiosity, but some use drugs to relieve stress and to forget about their problems. Genetic factors may predispose other individuals to drug addiction. Environment factors such as peer pressure, and the availability of drugs, also influence people to abuse drugs.

听力原文： Experts say some farming activities are seriously damaging Earth's environment. Bad farming methods can damage soil, forests and water supplies. They also have caused some plants and animals to disappear.
Two groups now say that bad farming methods are threatening the ability of farmers to produce enough food to feed the world population in the future.
The groups used satellite images, maps and modern equipment to study the effect of agriculture on the environment. The study found that the destruction of soil is widespread. Important organic nutrients are being removed from farmland.
Agriculture uses seventy percent of the freshwater in the world each year. The study found that many farmers are wasting water supplies. In addition, chemicals designed to protect crops may pollute waterways.
The report also says as much as thirty percent of the world's forests have been cut down so the land could be used for agriculture. This has led to a severe loss of wildlife and their environments.
