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.
disease.
B. regular fish-eating
C. the kind of fish eaten
D. people of different regions
B. the changes in people"s diet in the United States
C. the daily fish consumption of people in different cultures
D. the effect of fish-eating regularly on people"s health
B. Because American people drink too much spirits.
C. Because there are a great number of fat people there.
D. Because American people eat too much fatty fish.
Dutch study?
B. 110,000.
C. 275,000.
D. 852.
25,000,000 children, half of all schoolchildren in the country. But these buses, on average, use four liters of
diesel (柴油) fuel to travel less than sixteen kilometers. When the school year began last fall, diesel averaged
55 cents a liter nationally. The price nearly doubled, to a dollar and 8 cents, by the end of school in June.
Bob Riley speaks for the American School Bus Council. He says fuel prices for schools are not much
lower than others have to pay. As a result, schools are looking for ways to reduce transportation costs. Bus
routes are being redrawn or, in some cases, canceled (取消). Some areas are buying buses that use natural
gas or other alternative fuels. Other steps include fewer field trips and less travel by sports teams. And some
school districts (地区) may end any bus service not required by law.
Studies show that school buses are the safest form of transportation to and from school. The American
School Bus Council says cuts in bus service are bad for children and possibly the environment. It says
removing buses from the road will mean an increase in other vehicles transporting students. Spokesman Bob
Riley says another concern is that reducing bus services might reduce attendance.
But it could also get more children to walk or bicycle to school. And that would surely make people happy
at the National Center for Safe Routes to School. More kids walking or biking safely to school is the aim of a
three-year-old federal program, part of an international movement. The goal is to increase physical activity and
reduce air pollution. The United States will celebrate Walk to School Day on October eighth this year. But for
some students, high fuel prices could make every day a walk-to-school day.
B. New measures to transport school students.
C. The safest form of student transportation.
D. The origin of Walk to School Day.
B. There are too many students in the US.
C. Diesel prices are going up too rapidly in the US.
D. School buses consume too much diesel in the US.
B. The US government is encouraging cuts in bus services.
C. The US schools are searching for the safest transportation means.
D. Reducing bus service will do a lot of good to the environment.
B. stopping some bus routes
C. asking parents to drive children to and from school
D. using other types of fuels
order to _____.
B. keep the children safe on their way to school
C. make the children live a simple life
D. keep the children healthy and the environment clean
to a close.
When his heart problems led to operation, Jim went through it successfully, and a full recovery was
expected. Within days, however, his heart was not beating properly. Jim was rushed back to operation, but
nothing was found to explain the cause of his illness. He died on the operating table on the day before his 48th
birthday.
Dr. Bruce Smoller, a psychologist, had had many conversations with him, and the more he learned, the
stranger he realized Jim"s case was. When Jim was a child, his father, a teacher, suffered a heart attack and
stayed home to recover. One morning Jim asked his father to look over his homework, promising to come
home from school at noon to pick it up. His father agreed, but when Jim returned his father had died. Jim"s
father was 48.
"I think all his life Jim believed he killed his father," Dr. Smoller says. "He felt that if he had not asked him
to look at his homework, his father would have lived. Jim had been troubled by the idea. The operation was
the trial he had expected for forty years."Smoller believes that Jim willed himself not to live to the age of 48.
Jim"s case shows the powerful role that attitude plays in physical health, and that childhood experiences
produce far-reaching effect on the health of grown-ups. Although most cases are less direct than Jim"s, studies
show that childhood events, besides genes, may well cause such midlife diseases as cancer, heart disease and
mental illness.
B. he expected a full recovery
C. his life was drawing to a close
D. the first one wasn"t well performed
B. Jim died on the operating table.
C. Both Jim and his father died of the same disease.
D. Jim"s death is closely connected with his father"s.
B. Smoller agreed that Jim did kill his father
C. Jim thought he would be punished some day
D. Smoller believed Jim wouldn"t live to the age of 48
a. One"s genes.
b. One"s life in childhood.
c. One"s physical education.
d. The date of one"s birthday.
e. The opinions one has about something.
B. a, b, e
C. a, c, e
D. b, c, d
B. Jim often asked his father to do his homework.
C. Jim was believed to kill his father.
D. Most childhood events can cause cancer, heart disease and mental illness.
