If you smoke-particularly cigarettes-you are far more likely than a non-smoker to suffer or die from several major diseases-notably lung cancer.
One smoker in four dies prematurely (过早的) because of his smoking. The risk of dy-ing for a heavy smoker (between the ages of 35 and 55) is roughly equal to the risk run by a non-smoker 10 years older.
Cigarette smoking-and to a lesser degree pipe and cigar smoking--may aggravate (使恶化) or be partly responsible for the development of a wide variety of other diseases, which include cancers of the mouth and throat, peptic ulcers (胃溃疡), and loss of teeth.
Women who smoke during pregnancy produce babies on average about 5 to 8 ounces lighter than those who don't.
Take lung cancer for example.Britain's lung cancer figures are the highest in the world, and still rising. Ninety peo-ple die every day, 33,000 in 1969. Almost all these deaths can be attributed directly to to-bacco smoking. The prospects of a cure for lung cancer are, at present, remote, and it is impossible to estimate when, if ever, someone will find one. You would be foolish to rely on someone finding a cure before you needed it.
One man in eight who die between the ages of 35 and 64 is killed by lung cancer. The figures for women in this age group are lower, about 1 in 20. This is partly because women smoke less, and have not smoked as long. But the figures are still very high.
According to the passage, lung cancer______.
A. is the major cause of death between the ages of 35 and 55
B. is most often caused by smoking
C. never affects non-smokers
D. has nothing to do with smoking
The passage suggests that women______.
A. smoke as much as men
B. react better than men to smoking
C. are affected by smoking only during pregnancy
D. run the same risks as men if they smoke
A good example is the football World Cup. Football is the world's most important sport. Winning the World Cup is perhaps the summit of international sporting success. Mention "Argentina" to someone, and the chances are that he'll think of football. In a sense, winning the World Cup "put Argentina on the map."
Sports fans and supporters get quite irrational about the World Cup. People in Eng-land felt that their country was somehow important after they won in 1966. Last year thousands of Scots sold their cars, and even their houses, and spent all their money travel-ing to Argentina, where the finals were played.
So, am I arguing that international competition kills the idea of sport? Certainly not!(77) Do the Argentinian really believe that because eleven of their men proved the most skilful at football, their nation is in every way better than all others? Not really. But it's nice to know that you won and that in one way at least your country is the best.
What is the author's main purpose in the passage?
A. To prove that football is the world's most important sport.
B. To show that Argentina is better than all others.
C. To compare Scotland with Argentina.
D. To explain the role of sport.
