Dad,in a hurry to get home before dark so he could go for a run,had forgotten to wear his safety belt--a mistake 75% of the US population make every day.The big question is why.
There have been many myths about safety belts ever since their first appearance in cars some forty years ago.The following are three of the most common.
Myth Number One:It’s best to be“thrown clear”of a serious accident.
Truth:Sorry,but any accident serious enough to “throw you clear”is also going to be serious enough to give you a very bad landing.And chances are you’ll have traveled through a windshield(挡风玻璃)or door to do it.Studies show that chances of dying after a car accident are twenty-five times greater in cases where people are“thrown clear.”
Myth Number Two:Safety belts“trap”people in cars that are burning or sinking in water.
Truth:Sorry again,but studies show that people knocked unconscious(昏迷)due to not wearing safety belts have a greater chance of dying in these accidents,People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations,not to be trapped in them.
Myth Number Three:Safety belts aren’t needed at speeds of less than 30 miles per hour(mph).
Truth:When two cars traveling at 30 mph hit each other,an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.

habit of rushing through lift, being on the go from morning till night, it is hard to slow down. But relaxation
is essential for a healthy mind and body.
Stress is a natural part of everyday life and there is no way to avoid it. In fact, it is not the bad thing it
is often supposed to be. A certain amount of stress is vital to provide motivation and give purpose to life.
It is only when the stress gets out of control that it can lead to poor performance and ill healthy.
The amount of stress a person can withstand depends very much on the individual. Some people are
not afraid of stress, and such characters are obviously prime material for managerial responsibilities.
Others lose heart at the first signs of unusual difficulties. When exposed to stress, in whatever form, we
react both chemically and physically. In fact we make choice between "fight" or "flight" and in more
primitive days the choice made the difference between life or death. The crises we meet today are
unlikely to be so extreme, but however little the stress is, it involves the same response. It is when such
a reaction lasts long, through continued exposure to stress, that health becomes endangered. Such
serious conditions as high blood pressure and heart disease have established links with stress. Since we
cannot remove stress from our lives (it would be unwise to do so even if we could), we need to find
ways to deal with it.
B. they do not believe that relaxation is important for health
C. they are travelling fast all the time
D. they are becoming busier with their work
B. knowing the art of relaxation
C. high sense of responsibility
D. having control over performance
B. Stress is always harmful to people.
C. It is easy to change the habit of keeping oneself busy with work.
D. Different people can withstand different amounts of stress.
B. "reaction to stress both chemically and physically"
C. "responding to crises quickly"
D. "losing heart at the signs difficulties"
B. "find ways to deal with stress"
C. "remove stress from our lives"
D. "established links between diseases and stress"
Life in 2060
Let us suppose it is now about A.D. 2060. Let"s make believe it is about fifty years from now. Of
course, things have changed and life is very different.
Voyages to the moon are being made every day. It is as easy to take a holiday on the moon today as
it was for the people in 1960 to take a holiday in Europe. At a number of scenic spots on the moon, many hotels have been built. The hotels are air conditioned, naturally. In order that everyone can enjoy the
beautiful scenery on the moon, every room has at least one picture window. Everything imaginable is
provided for entertainment of young and old.
What are people eating now? People are still eating food. They haven"t yet started to take on heir
(继承) supply of energy directly as electrical current or as nuclear power. They may some day. But many
foods now come in pill form, and the food that goes into the pill continues to come mainly from green
plants.
Since there are several times as many people in the world today as there were a hundred years ago,
most of our planet"s surface has to be filled. The deserts are irrigated with water and crops are no longer
destroyed by pests. The harvest is always good.
Farming, of course, is very highly developed. Very few people have to work on the farm. It is possible
to run the farm by just pushing a few buttons now and then.
People are now largely vegetarians (素食者). You see, as the number of people increases, the
number of animals decreases. Therefore, people have to be vegetarians and we are healthier both in our
bodies and in our minds, and we know the causes and cure of disease and pain, and it is possible to get
rid of diseases. No one has to be ill any more.
Such would be our life in 2060.
1. When was the passage written? ( no more than 5 words)
2. According to the passage, what does each room of the hotels have on the moon? (no more than 8
words)
3. What will people eat then according to the passage? (no more than 5 words)
4. Why are people largely vegetarians in 2060? (no more than 7 words)
There are various reasons why cancers appear to be on the increase. For one thing, though their
sufferers are to be found in all age groups, cancers are particularly likely to attack persons in their
middle and advanced years. Naturally, since people live longer these years, there are more cancer
sufferers than before. Again, with better methods of diagnosis (诊断), doctors can more easily
recognize cancerous growths that would formerly have passed unnoticed or that would have been
wrongly diagnosed. It is also believed that certain habits and conditions of modern living, including
heavy smoking and the pollution of the air, may leave people living in more cancer-causing conditions
than before.
We all look forward to the day when a simple medical test can find cancer while it is still small.
Researchers around the world are working on such a test. Most of their work deals with the
examination of the blood.
Researchers in Boston have found something in the blood of cancer patients that does not
appear in healthy persons. The test showed which persons had cancer and which did not. It was
correct more than 90 percent of the time. The researchers believe the test may be able to show
cancer very clearly in its development. Cancers discovered early usually can be treated successfully.
The test examines very small bits of fat in the blood called lipids (脂质). Cancers seem to change
lipids although doctors do not know why. The test showed differences between the lipids of the
persons with cancer and the lipids of those without cancer. The researchers say the new test could
be a step to develop a simple way to check patients for cancer before the disease shows on an X-ray.
1. Who will have cancer from the study of the researchers?
A. The young.
B. The middle age and the older.
C. The man.
D. The woman.
2. The underlined words "such a test" refer to________.
A. the test that shows which persons have cancer and which don’t .
B. the test that may be able to show cancer very early in its
development。
C. a simple medical test that cannot find cancer when it is small
D. a new test that could be a step to develop a difficult way
3. Which of the following statements is true according to the passage?
A. Cancers have much to do with something in patients’ blood.
B. People living in better conditions are most likely to be attacked by
cancer.
C.X-raying is the best way to determined whether a person has cancer
or not.
D. Cancers have nothing to do with a person’s habits and living
conditions.
4. What would be the best title for the passage?
A. A simple way to cancer
B. Cancers can be cured
C. How to find cancer
D. Early discovery of cancer

Prolonging human life has increased the size of the human population. Many people alive today
would have died of childhood diseases if they had been born 100 years ago. Because more people live l
onger, there are more people around at any given time. In fact, it is a decrease in death rates, not an
increase in birthrates, that has led to the population explosion.?
Prolonging human life has also increased the dependency load. In all societies, people who are
disabled or too young or too old to work are dependent on the rest of society to provide for them.
In hunting and gathering cultures, old people who could not keep up might be left behind to die. In times
of famine(饥荒), infants might be allowed to die because they could not survive if their parents starved,
but if the parents survived they could have another child. In most contemporary(当代的) societies,
people feel a moral responsibility to keep people alive whether they can work or not. We have a great
many people today who live past the age at which they want to work or are able to work; we also have
rules which require people to retire at a certain age. Unless these people were able to save money for
their retirement, somebody else must support them. In America many retired people live on social
security checks which are so little that they must live in near poverty. Older people have more illness
than young or middle-aged people; unless they have wealth or private or government insurance, they
must often “go on welfare” if they have a serious illness.?
When older people become senile (衰老的) or too weak and ill to care for themselves, they create
grave problems for their families. In the past and in some traditional cultures, they would be cared for
at home until they died. Today, with most members of a household working or in school, there is often
no one at home who can care for a sick or weak person. To meet this need, a great many nursing
homes and convalescent (疗养的) hospitals have been built. These are often profit-making
organizations, although some are sponsored(主办) by religious and other nonprofit groups. While a
few of these institutions are good, most of them are simply “dumping (倒垃圾的) grounds” for the
dying in which “care” is given by poorly paid, overworked, and under-skilled personnel.?
1.The author believes that the population explosion results from
A.an increase in birthrates
B.the industrial development?
C.a decrease in death rates
D.human beings" cultural advances
2.According to the passage, which of the following statements about the old people in America is
TRUE?
A.Many of them live on social security money which is hardly enough.?
B.Minority of them remain in a state of near poverty after their
retirement.
C.When they reach a certain age, compulsory retirement is necessary and
beneficial.
D. With the growing inflation(通货膨胀), they must suffer more from unbearable burdens than ever?
3.The underlined phrase “this need” in Paragraph 3 refers to ?
A.prolonging the dying old people"s lives?
B.reducing the problems caused by the retired people?
C.making profits through caring for the sick or weak people?
D.taking care of the sick or weak people?
4.Which best describes the author"s attitude toward most of the nursing homes, and convalescent
hospitals??
A.Sympathetic.
B.Approving.
C.Optimistic.
D.Critical.
"pure beauty" in Zhang Yimou"s new movie Under the Hawthom Tree.《山揸树之恋》
The film tells the story of the sad romance of Jingqiu and a handsome young man named Laosan. Set at
the end of the "cultural revolution" (1966-1976), the pair manage to fall in love although they come form
different political environments.
Before it was released, moviegoers speculated (推测) on just what this "pure beauty" could be.
Director Zhang complained of how long it had taken him to find the right girl for the part of Jingqiu-a
character so innocent that she believes simply lying on the same bed with a man will make her pregnant.
It was 18-year-old Zhou Dongyu who stood out from the crowd. According to Zhang, Zhou has "eyes
that are clear like a fountain on a mountainside". Born of an ordinary worker"s family, the Shijiazhuang girl
was in her final year of high school and working hard for a place in an art college.
While some teenagers consider such "pure beauty" illusory (虚幻的), others believe that it speaks of
something soulful.
Purity is all about the innocence that shines through from within, thinks 16-year-old Tan Mengxi of
Nanjing.
"Being pure can be simple, not having complicated thoughts and being inexperienced. However, it
doesn"t mean an ignorant or naive (天真的) person. So, a person is pure in his or her nature if he or she is
always enthusiastic and able to deal with difficult matters independently. This purity doesn"t pass with time,"
she said.

C. A romantic girl.
D. A silent girl
B. A girl has eyes that are clear like a fountain on a mountainside.
C. A girl who was born into an ordinary worker"s family.
D. A girl wears accessories and make-up.
B. Being pure can be simple, not having complicated thoughts and being inexperienced.
C. It is of whether someone is always enthusiastic.
D. Purity is a matter of internal quality and doesn"t pass with time.
B. A debate on the movie Under the Hawthorn Tree
C. Opinions on the character Jingqiu
D. It"s hard to find the character Jingqiu
B. In the 1980s
C. In the 1970s
