     Ali is from a Middle Eastern country. He now stays in the USA. He smokes a lot of cigarettes (香烟) every

day. He has smoked for nine years. Ali says," I tried to quit (放弃) smoking in my hometown, but it was

impossible. My brothers smoke. All my friends smoke. At parties and at meetings, almost all the men smoke.

Here in the United States, not as many people smoke. It will be easier to change my habit here."

     Many smokers are like Ali: they want to stop smoking. The smokers know that smoking is bad for their

health. They know it can cause cancer and heart disease. But it is difficult for them to give up smoking because cigarettes have a drug in them. The drug is nicotine (尼古丁). People who smoke a lot need nicotine.

     When a person first begins to smoke, he usually feels terrible. The nicotine makes him sick. In a few days,

the smoker's body is used to the nicotine, and he feels fine. Later, the smoker needs nicotine to keep feeling fine. Without nicotine, he feels bad.

     It is very hard to quit smoking, and many people who quit will soon smoke again. At a party or at work they will decide to smoke "just one" cigarette. Then they will smoke another cigarette, and another. Soon they become smokers again. Maybe there is only one easy way to quit smoking: never start.

Can trees talk? Yes — but not in words. Scientists have reason to believe that trees do

communicate with each other. Not long ago, researchers learned some surprising things. First a willow tree attacked in the woods by caterpillars(毛毛虫)changed the chemistry of its leaves and made them taste so terrible that they got tired of the leaves and stopped eating them. Then even more astonishing, the tree sent out a special vapor—a signal causing its neighbors to change the chemistry of their own leaves and make them less tasty.

Communication, of course, does not need to be in words. We can talk each other by smiling, raising our shoulders and moving our hands. We know that birds and animals use a whole vocabulary of songs, sounds, and movements. Bees dance their signals, flying in certain patterns that tell other bees where to find nectar for honey. So why shouldn’t trees have ways of sending messages?

A.have an unpleasant taste

B.are lying on the ground

C.have an unfamiliar shape

D.bees don’t like

2.According to the passage, the willow tree was able to communicate with each other by       .

A.waving its branches              B.giving off a special vapor

C.dropping its leaves               D.changing the color of its trunk

3.According to the passage, bees communicate by        .

A.touching one another             B.smiling one another

C.making special movement         D.making unusual sound

4.The author believes that the incident described in the passage         .

A.cannot be taken seriously          B.seems completely reasonable
