参考答案:
Key Points: ①The World Health Organization estimates that more than four million people die each year from the effects of cigarette smoke. The number is increasing.
②Smoking not only leads to lung cancer but many other diseases such as heart attacks, sore throats, headaches, chronic bronchitis, etc.
③Doctors say that you will probably live longer if you stop smoking. You will feel better and look better. You will also protect the health of family members who breathe in your smoke.
④The World Health Organization claims that diseases linked to smoking are responsible for at least B,E00,000 deaths in every year.
⑤An American scientist estimated that smokers who average a packet a day for B0 years will lose about eight years of their lives.
⑥Pregnant women who smoke run the risk of having deformed babies.
⑦Children exposed to parental cigarette smoking are put at a higher risk of developing lung diseases later in their lives.
⑧Nicotine can have a tranquilizing effect in highly emotional situations, therefore helping to calm people down, and wipe out their fatigue.
⑨Most research workers in this field believe that cigarette smoke is an important factor in the development of cancer of the lungs and cancer of the throat. It is also believed to be related to cancer of the bladder and the oral cavity.
⑩Male cigarette smokers have a higher death rate from heart disease than men who do not smoke. Female smokers are thought to be less affected because they do not breathe in the smoke so deeply.
[*]Smoking is considered a health hazard because tobacco smoke contains nicotine, a poisonous alkaloid, and other harmful substances such as carbon monoxide, acrolein, ammonia, prussic acid, and a number of aldehydes and tars.
[*]Smokers have a significantly greater chance of contracting lung cancer than nonsmokers, the rate varying according to factors such as the number of cigarettes smoked per day, the number of years the subject smoked, and the time in the person’s life when he or she began smoking.
[*]Cigarette smoke was also found to be an important cause of cancers of the oesophagus, nasopharynx, mouth, larynx, kidney, and bladder as well as a cause of chronic obstructive pulmonary disease, emphysema, heart disease, strokes, and other cardiovascular diseases.
[*]Nowadays, smoking is popular. There are a large number of smokers all over the world. Even some teenagers smoke. If you ask them, "Why do you smoke " They might answer, "Don’t you know It is cool. " But it is really a cool thing to do I’m afraid I can’t agree to this.
[*]Smoking is not only harmful to the smokers themselves, but also results in the deaths of nonsmokers.
[*]Statistics show that passive smoking is causing C000 to E000 lung cancer deaths a year among American nonsmokers.
[*]Smoking makes the indoor environment far more polluted than the outdoor environment.
[*]Smoking not only pollutes the air but also makes the streets dirty, for some smokers flick the ash off their cigarettes and throw their cigarette butts on the ground.
[*]In this way smoking spoils the beauty of our countryside and is bad for our environment.
[*]Smoking is an expensive habit, a smoker who consumes a packet of cigarettes a day will have to spend at least A00 yuan each month -- more than one third of the average salary in China.
[*]Buying tobacco is a waste of money. Normally, it costs a smoker C to E yuan a day for his cigarettes. That is about a hundred yuan a month, or about one thousand yuan a year. We have so many better ways to use this money, why do we spend it on something that is harmful to our health
[*]Smoking consumes a great deal of money. Smoking wastes B00 billion dollars each year around the world. Smoking harms the health of smokers and is the main cause of lung cancer. About three billion people die from diseases related to smoking every year.
[*]More and more people are aware of how harmful smoking is. Tobacco consumption is on the decrease. This tendency is made clear by the following figures: in AIID the amount of tobacco produced worldwide totalled AD. CFD billion pounds. This figure dropped to AD.B billion pounds in AIIE. At the same time, many countries called people to give up smoking. The number of smokers is certainly on the decrease, but how to solve the other problems mentioned above
