| Now medical researchers are discovering
a truism: "alcohol and tobacco do not mix." These two substances, both dangerous
to health, act synergistically, each making the other more powerful and thereby
causing worse damage than either would do alone. Because of this interaction, the person who both smokes and drinks heavily may be at a greater risk of becoming ill than one who drinks like a fish, but never smokes or who smokes like a chimney, but never drinks. To get an idea of how this synergism may work, consider what happens when a smoker lights up a cigarette. With each puff he inhales at least 4,000 different chemicals. These include toxic hydrogen-cyanide, carbon monoxide and nitrogen-dioxide gases, and four dozen compounds such as benzo pyrene and radioactive polonium 210. All are known as carcinogens.

A.正确 B.错误 [填空题]Joan Thomas:
My husband has been reduced to the condition of a vegetable. Keeping him alive is meaningless now. I’m sure that if he could speak, he would beg us to switch off that oxygen machine. Why can’t he die of dignity Seeing him in this condition is causing us all great suffering. He has been in a coma for more than five months and is being kept alive by this machine which supplies him with oxygen. I have applied to a court for permission to have the machine switched off. I believe that he would rather have died peacefully than prolonged suffering for such a long time. Doctor Williams: Mr. Thomson is clinically alive, but he has absolutely no chance of recovery. His brain has been irreparably damaged by the coma. He could remain in this condition for years. Frankly speaking, that would benefit nobody. Hospital beds are scarce and medical staff are very busy.
