seriously. Now however, doctors have begun to look into laughter and the effects it has on the human body.
They have found that laughter really can improve people"s health.
Tests were carried out to study the effects of laughter on the body. People watched funny films while
doctors checked their heart, blood pressure, breathing and muscles. It was found that laughter has similar
effects to physical exercise. It increases blood pressure, makes the heart beat quicker and makes people
breathe deeper; it also works several groups of muscles in the face, the stomach, and even the feet. If laughter
exercises the body, it must be beneficial.
Other tests have shown that laughter appears to be able to reduce the effect of pain on the body. In one
experiment doctors produced pain in groups of students who listened to different radio programmes. The
group that tolerated (忍耐) the pain for the longest time was the group which listened to a funny programme.
The reason why laughter can reduce pain seems to be that it helps to produce a kind of chemical in the brain
which diminishes both stress and pain.
As a result of these discoveries, some doctors in the United States now hold laughter clinics, in which they
help to improve their patients" condition by encouraging them to laugh. They have found that even if their
patients do not really feel like laughing, making them smile is enough to produce beneficial effects similar to
those caused by laughter.

babies" lungs. They say reduced lung growth could cause the babies to suffer breathing problems and lung
diseases later in life. Doctors in Boston, Massachusetts studied 1,100 children. The mothers of some of the
children smoked, the other mothers did not. Doctors found that the lungs of the children whose mothers
smoked were 8% less developed than the lungs of the children whose mothers did not smoke, and that the
children whose mothers smoked developed 20% more cold and breathing diseases than other children later
in life.
Another recent study found that children had a greater chance of developing lung cancer if their mothers
smoked. The study also showed that the danger of lung cancer increased only for sons and not for daughters,
and that the father"s smoking did not affect a child"s chance of developing lung cancer.
( )2. Mothers who smoked did not reduce the growth of their children"s lungs.
( )3. The lungs of the children whose mothers smoked were 8% less developed than those of other children.
( )4. Suppose John"s father was a heavy smoker, so was Mary"s mother. According to the text, neither John
nor Mary has the chance to develop lung cancer.
( )5. The text is to warn us of the danger of smoking before children.
better health. According to the latest figures, 59 percent of American adults exercise regularly-up 12 percent
from just two years ago and more than double the figure of 25 years ago. Even non-exercisers believe they
would be more attractive and confident if they were more attractive.
It is hard not to get the message. The advantage of physical fitness are shown on magazine covers, postage
stamps, and television ads for everything from beauty soaps to travel books. Exercise as a part of daily life did
not catch on until the 1960s when research by military doctors began to show the health benefits of doing
regular physical exercises. Growing publicity for races held in American cities helped increase a strong interest
in the ancient sport of running. Although running has leveled off in recent years as Americans have discovered
equally rewarding-and something safer-forms of exercise, such as walking and swimming, running remains the
most popular form of exercise.
As the popularity of exercise continues to increase, so does scientific evidence of its health benefits. The
key to fitness is exercising the major muscle group strongly enough to double the heart rate and keep it doubled
for 20 to 30 minutes at a time. Doing such physical exercises three times or more a week will produce
considerable improvements in physical health in about three months.

Some parents try to get rid of half of the candy after their children go to bed, but dentists say parents also need
to separate the good kinds of treats from the bad.
It is not exactly what a child eats that truly matters, but how much time it stays in his mouth. According to
pediatric dentists Dr Kaneta Lott, the most damaging stuff is something that is sticky or very hard and thus stays
in the mouth for a long time. This is because we all have bacteria in our mouths. When we eat, the bacteria take
our food as their food and produce an acid that destroys the surface of the teeth, causing cavities to form. The
longer the food stays in the mouth, the more likely cavities will develop. Therefore, potato chips are worse than
candy because they get stuck between teeth. For the same reason, raisins and crackers are not the best choice.
Hard candies take a long time to consume and are also a bad choice for Halloween treats.
If children really love candy, dentists recommend that they eat chocolate instead. Unlike hard candies,
chocolate dissolves quickly in the mouth. Besides, chocolate contains tannins, which help to kill some of the
bacteria in the mouth. But no matter what a child eats, brushing after each meal is still the best way to fight
cavities.
B. To point out the problems with Halloween celebrations.
C. To tell parents what sweets are less damaging to their children"s teeth.
D. To teach parents the meaning of Halloween candies for their children.
B. They help bacteria to produce tannins.
C. They contain too much sugar.
D. They stay in the mouth for a long time.
B. Crackers
C. Raisins
D. Potato chips
B. They help to get rid of some bacteria in the mouth.
C. They help chocolate to dissolve more quickly.
D. They destroy the surface of the teeth.
Dutch men in which deaths from heart disease were more than 50 percent lower among those who consumed
(吃) at least an ounce of salt water fish per day than those who never ate fish.
The Dutch research is one of three human studies that give strong scientific backing to the long-held belief
that eating fish can provide health benefits, particularly to the heart.
Heart disease is the number-one killer in the United States, with more than 550, 000 deaths occurring from
heart attacks each year. But researchers previously have noticed that the incidence (发生率) of heart disease is
lower in cultures that consume more fish than Americans do. There are fewer heart disease deaths, for example,
among the Eskimos of Greenland, who consume about 14 ounces of fish a day, and among the Japanese,
whose daily fish consumption averages more than 3 ounces.
During the last two decades, 78% of the men died from heart disease. The fewest deaths were among the
group who regularly ate fish, even at levels far lower than those of the Japanese or Eskimos. This relationship
was true regardless of other factors such as age, high blood pressure, or blood cholesterol (胆固醇) levels.
B. There is a low incidence of heart disease in countries like Japan and Greenland.
C. Among all the diseases heart disease is the most dangerous in America.
D. Heart doctors won"t call your house so long as you keep eating fish each day.
