For years , many people would not believe that smoke could attack so many parts of the body in so many ways . Study shows , however , that tobacco isn’t one single thing .  At least 60% of it is gas—20 different kinds of gas . And one of these is the deadly carbon monoxide (CO) （一氧化碳）.
In factories , the amount of this gas in the air is measured , and it must be kept under fixed , safe level . But there is 640 times this safe amount in cigarette smoke .
Oxygen is carried through your body by the red blood cells . But this poison gas , CO, will get to the blood cells before the oxygen can . So , if you smoke your blood carries five to ten times more of this deadly gas than is normal . To make up for this , your body must make more red cells .
The oxygen in your blood passes into your tissues（組織）. But here again CO makes trouble . It keeps the oxygen from passing into your tissues as fast as it should . Because of this , cigarette country is always about 8000 feet above sea level . Someone who smokes and lives at sea level gets as little oxygen as a nonsmoker at an altitude（高度）of nearly two miles .This happens to everyone who smokes , no matter how old or how young . Anyone who competes in sports can tell you that those who smoke run out of breath more quickly than those who do not .

When thinking about quitting(停止) smoking…
List all the reasons why you want to quit. Every night before going to bed, repeat one of the reasons 10 times.
Decide positively that you want to quit. Try to avoid negative thoughts about how difficult it might be. Develop strong personal reasons as well as your health and responsibility to others. For example, think of all the time you waste taking cigarette breaks, rushing out to buy a pack, hunting a light, etc. Set a date for quitting --- perhaps a special day like your birthday, a holiday. If you smoke heavily at work, quit during your vacation. Make the date seriously, and don't let anything change it. Begin to condition yourself physically; start a modest (適當(dāng)?shù)? exercise; drink more water; get plenty of rest.
Immediately after quitting...
The first few days after you quit, spend as much free time as possible in places where smoking is prohibited, e.g. libraries, museums, theatres, department stores, etc.
Drink large quantities of water and fruit juice. Try to avoid wine, coffee, and other drinks which remind you of cigarette smoking.
Start a conversation with someone instead of a match for a cigarette.

第二節(jié) 信息匹配（共5小題；每小題2分，滿分10分）
閱讀以下應(yīng)用文及相關(guān)信息，并按要求匹配信息。
以下是有關(guān)吸煙問題的觀點：

A． Smoking is sure to cause diseases. Just have a look at those people with diseases in hospital and count how many of them do not smoke; you may be surprised at the number. Even these few people might be passive smokers without realizing it.
B．We have to admit that the tobacco industry contributes a lot to many countries' economies. It also creates job opportunities. But it's harmful to people in the long run. It's a short-sighted policy to depend on tobacco for money.
C．Non-smokers absorb nicotine and other harmful chemicals just as smokers do. This is an especially bad situation for children — some of them absolutely have no choice but to be passive smokers and to have lungs that are not as healthy as a normal child's.
D． Despite all the strict laws against smoking, the statistics have shown that more young people are lighting up. While it was absolutely a taboo (禁忌) for a woman to smoke before, now it's quite common to see young girls smoking. Many even walk around with a lighted cigarette in one hand.
E. However, smokers may feel a certain amount of pressure. On the one hand, they might feel guilty about the amount of money they spend on cigarettes each month, which could have been put to much better use, but on the other hand, they may also feel non-smokers should be more tolerant of them.
F.    Smoking can provide constant consolation. When people feel worried or nervous, they just get a cigarette and everything seems to get right After a day's hard work, what they want to do most is smoking. It can be even better than drinking a cup of coffee.
以下是個人對吸煙的認識，請匹配個人的認識與相應(yīng)的觀點。
56．Christopher: As a matter of fact, smokers are under a great deal of pressure, not only because they spend so much money on cigarettes but also because they don' t think people around them are tolerant enough of them.
57．Amanda: If you smoke and you still don't believe that there's a definite link between smoking and bronchial(支氣管的) troubles, heart disease and lung cancer, you are certainly deceiving your­self.
58．Harrison: Smoking brings some psychological benefits. Most smokers feel it's enjoyable and that it can relieve daily stress. So why must we ban it and take away a lot of people' s pleasure?
59．Brandon: Forbidden fruits always taste sweetest. That is to say, the stricter the laws against smoking are, the more people want to smoke. What worries me is that more young people are beginning to smoke.
60．Douglas: If there were some ways to stop a smoker from affecting others, I wouldn't object to smoking! Secondhand smoke does great harm to non-smokers, especially to children, who are much more sensitive than adults.
