Why do people smoke? One reason is that people become addicted(成瘾) to cigarettes. The addictive substance(物质)in cigarettes is nicotine(尼古丁). When people smoke, the nicotine goes right into the blood stream and makes people feel comfortable. A smoker's body gets used to the nicotine, and if he stops smoking, he feels nervous. Many smokers try to stop smoking but because of the addiction to nicotine they feel so uncomfortable that they often find it too difficult____.

Another reason is that people simply enjoy smoking. Having a cigarette for many people means taking a break. For some people smoking becomes part of certain social rituals (礼仪), for example, sending the cigarette after dinner. Many people enjoy smoking because it gives them something to do with their hands. Reaching for a cigarette, lighting it and flicking (弹掉) the ashes are special comfort in a situation where they feel nervous.

Many people also like the taste of tar (焦油) in cigarettes. However, it is the tar that causes cancer. While governments and health experts have tried to get people to give up smoking completely, cigarette manufacturers (生产商) have tried to keep selling them by producing cigarettes with less tar. Many people in western countries have welcomed these cigarettes since they found it hard to stop smoking and wanted to reduce the danger to their health.

Many people know that rubbish is a big problem on planet Earth. What many people don't know is that junk(垃圾)has become a problem in outer space too.

According to BBC News, there are more than 22, 000 pieces of space junk floating around the earth. And these are just the things that we can see from the surface of the earth by telescopes (望远镜). There are also millions of smaller pieces of junk that we can't see.

Objects, like bits of old space rockets or satellites, move around the planet at very high speeds fast that even a very small piece can break important satellites or become dangerous to astronauts. If the tiniest piece of junk crashed into a spaceship, it could damage the vehicle.

To make things worse, when two objects in space crash, they break into many smaller pieces. For example, when a U.S. satellite hit an old Russian rocket in 2009, it broke into more than 2,000 pieces, increasing the amount of space junk.

To reduce additional space junk, countries have agreed that all new space tools can only stay in space for 25 years at most. Each tool must be built to fall safely into the earth's atmosphere after that time. In the upper parts of the atmosphere, it will burn up.

Many scientists also suggesting different ways to clean up space junk. In England scientists are testing a metal net that can be fired into space junk. The net catches the junk and then pulls it into the earth's atmosphere to burn up. The Germans are building robots that can collect pieces of space junk and bring them back to Earth to be safely destroyed.

The problem is becoming more challenging because we're sending more objects into space to help people use their mobile phones and computers,” says Marco Castronuovo, an Italian space

Researcher.

“The time to act is now. The longer we leave the problem, the bigger it will become,” he says.
