Wang Bing’s father began smoking when he was in college. His friend passed him his first cigarette(香烟). He has now been smoking for more than 30 years.It’s an example of how young people are introduced to cigarettes，except that nowadays smokers develop their habit at an even younger age.It has become a main worry in China that many teenagers begin to smoke. A showed that 22.5 % of the middle school students questioned had tried smoking and 15.8% of them smoked regularly(经常).For many teenagers, smoking is a symbol of being an adult，matiirity (成熟) and attractiveness because the images who they love best often smoke on screen.
The social environment also plays an important role in attracting(吸引）teenagers, to smoking. They are used to seeing their elders, especially male (男性）family members, smoking at home. Many of them imitate adult behavior and become new smokers.
To increase the price of cigarettes is a useful way to reduce the number of young smokers, as teenagers have no enough money to spend on them.
Another way is to teach the teenagers to refuse cigarettes. A survey shows that 92.5% of the students know smoking will be bad for their health. If we tell them, in a proper way, most of them may give up smoking.
All in all, the society, the government, the school and the family should join together to take the responsibility(责任）for an anti-smoking(禁烟)act aimed at teenagers，not just to put empty words and warnings on cigarette packs.

A new study finds that plants communicate with one another to warn of danger.
We often consider plants as the furniture of the natural world. They don’t move; they don’t make sounds；they don’t seem to act on anything. But as is often the case, plants talk to each other all the time. And the language is a chemical (化学物质).
Over the years, scientists have reported that different types of plants, from trees to tomatoes, give out chemicals into the air to help neighbouring plants. These chemical warnings can spread information about one plant’s disease or infestation (虫害)，so other plants can protect themselves. But how plants receive and act on the information exactly is still mysterious (神秘的）.
In this week’s Science Magazine, researchers in Japan offered some explanations. They have found out one chemical message and traced it all the way from beginning to end.
The scientists looked at tomato plants infested by a common pest (害虫）.To start out，they grew plants in two separate plastic spaces connected by a tube (管子）. One plant was infested and placed upwind and the other was uninfested and placed downwind. The downwind plants were later exposed (暴露的）to the pest. The results showed that plants near sick neighbours before were able to protect themselves better against the pest.
They found one chemical appeared more often in the exposed plants. The chemical is called HexVic. The scientists discovered where HexVic came from, and put it over healthy plants. Those plants were then able to produce HexVic. Researchers made sure that uninfested plants could fight off bugs and diseases. How do they know when to protect themselves? They are warned first by their friendly plant neighbours.
It is not a simple story , and it may be happening in many other plants besides tomatoes. It may also be happening with more chemical signals that are still unknown to us. In a word, we know that plants not only communicate, but also look out for one another.
( )57. The underlined word “traced” in the fourth paragraph probably means _______here.
A. reported B. followed C. doubted D. developed
( )58. For scientists, which are the right steps to watch tomato plants infested by a pest?
① Place the infested plant upwind.
② Place the uninfested plant downwind.
③ Expose the downwind plants to the pest.
④ Grow plants in two separate plastic spaces connected by a tube.
A.③①②④ B.①④③② C.④①②③ D.④②①③
( )59. You can put the sentence “The researchers also studied leaves from exposed plants and unexposed plants." at the beginning of Paragraph ____.
A. 3 B. 4 C. 5 D.6
( )60. Which of the following can be the best title of this passage?
A. Communicating Plants and Terrible Diseases
B. Talking Plants and Friendly Warnings
C. Protecting Plants and Clear Information
D. Growing Plants and Mysterious Chemicals
