_____. Fifty years ago, only 4 out of every 100 people in the United States were 65 or older. Today, 10
out of every 100 Americans are over 65. The aging of the population will affect American society in many
ways: education, medicine, and business. Quietly, the growing of America has made it a very different society,
one in which people have a quite different idea of what kind of behavior is suitable at various ages.
A person"s age no longer tells you anything about his or her social position, marriage or health. There"s no
longer a particular year in which one goes to school or goes to work or gets married or starts a family. The
social clock that kept us on time and told us when to go to school, get a job, or stop working isn"t as strong
as it used to be. It doesn"t surprise us to hear of a 29-year-old university president or a 35-year-old grandmother,
or a 70-year-old man who has become a father for the first time. Public ideas are changing.
Many people say, "I am much younger than my mother or my father was at my age." No one says, "Act
your age" any more. We"ve stopped looking with surprise at older people who act in youthful ways. |
1. What is mainly talked about in the passage? (Within 12 words)

How can you find out what is going on inside a person"s body without opening the patient up? Regular
X-rays can show a lot. CAT scans can show even more. They can give three-dimensional (三维) view of
body organs(器官).
What is a CAT scan? CAT stands for Computerized Axial Tomography (层面X线照相术). It is a special
X-ray machine that gets a 360 - degree picture of a small area of a patient"s body.
Doctors use X-rays to study and examine diseases and injuries within the body. X-rays can find foreign
objects inside the body or to take pictures of some organs inside if special things as dyes or special liquids
are added to the organs to be X-rayed.
A CAT scanner, however, uses a beam (光束) of X-rays to give a cross-sectional view of a particular
part of the body. A fine beam of X-rays is scanned across the body and circled around the patient from many
different angles (角度). A computer analyzes (分析) the information from each angle and produces a clear
cross-sectional picture on the screen. This picture is then photographed for later use. Several cross-sections,
taken one after another, can give a clear "photo" of the entire body or of any body organs. The newest CAT
scanners can even give a clear picture of active, moving organs just as a fast-action camera can "stop the
action" giving clear pictures of what appear only mistily (模糊) to the eye. And because of the 360-degree
pictures, CAT scans show 3-dimensional views of organs in a manner that was once only seen during surgery
or autopsy (examining a dead body). |

A. giving the patient an operation
B. checking body organs
C. getting a 360-degree picture of a small area of a patient"s body
D. examining the CAT |
| 2. From the last paragraph, we can infer that _____. |
| [ ] |

B. many pictures can be taken at the same time
C. the information about the scanned patient is not highly valued
D. some pictures of the scanned parts of the body are developed for further examinations in the future |
| 3. The best title of this passage might be _____. |

The hole in the Earth"s ozone layer (臭氧层) has until now protected Antarctica from the worst effects of
global warming. But scientists have warned that as the hole closes up in the next few decades, temperatures
on the continent could rise by around 3oC on average, with melting ice contributing to a global sea level
increase of up to 1.4 metres.
In the past decades the western Antarctic has seen rapid ice loss as the world has warmed, but the other
parts of the continent have, paradoxically, been cooling, resulting in a 10% increase in ice in the seas around
the region. This is because the hole in the ozone layer has increased cold winds in Antarctica, making much
of the continent surface colder than usual.
But now that the gasses that cause the ozone hole have been banned, scientists expect the hole to repair
itself within the next 50 to 60 years. By then the cooling effect will have faded out and the Antarctic will face
the full impact of global warming. This means an increase in average air temperatures of around 3OC and a
reduction in sea ice by around a third.
The biggest threat to the continent comes from warming seas. Robert Johnson, a scientist who monitors
Antarctica ice sheets, said, "The ice sheets in Antarctica are hundreds of metres thick. But once warm ocean
waters start flowing underneath, the ice will begin thinning and could break up very quickly." Thinning ice
sheets cause ice to break away from the continent and to melt even faster. Escaping ice from western
Antarctica has already resulted in a 10% rise in global sea level in recent decades.
Johnson believes that international action to reduce global warming is required immediately or it may be too
late. "Everything is connected-Antarctica may be a long way away but it is an important part of the Earth"s
system," said Johnson. "It contains 90% of the world"s ice, 70% of the world"s fresh water and that is enough,
if it melts completely, to raise sea levels by 63 metres."
Even in a worse-case situation scientists don"t expect the ice to entirely disappear, but predict that, because
of the melting ice sheets, average sea level rise will be around 1.4 metres higher by the end of the century. |

Alzheimer"s disease affects millions of people around the world. American researchers say the disease
will affect more than one hundred million people worldwide by the year twenty fifty. That would be four
times the current (现在的) number. Researchers and doctors have been studying Alzheimer"s patients for
a century. Yet the cause and cure for the mental (智力的) sickness are still unknown. However, some
researchers have made important steps towards understanding it.
Several early signs of the disease involve (涉及) memory and thought processes. At first, patients have
trouble remembering little things. Later, they have trouble remembering more important things, such as the
names of their children.
There are also some physical tests that might show who is at risk of developing Alzheimer"s disease.
The tests look for proteins (蛋白质) in brain and spinal cord fluid (脊髓). The proteins appear to be found
only in people with the disease. The protein tests correctly identify (确定) the presence of the disease in
about ninety percent of patients.
Now, a much simpler physical test to predict Alzheimer"s risk has been developed. Researchers found
that trouble with the sense of smell can be one of the first signs of Alzheimer"s disease. Using this information,
they developed a test in which people were asked to identify twelve familiar smells. These smells included
cinnamon (桂皮), black pepper, chocolate, paint thinner (涂料稀释剂), and smoke.
The study continued for five years. During this period, the same people were asked to take several tests
measuring their memory and thought abilities. Fifty percent of those who could not identify at least four of
the smells in the first test had trouble with their memory and thinking in the next five years.
Another study has shown a possible way to reduce a person"s chances of developing Alzheimer"s disease
in old age. Researchers in Chicago found that people who use their brains more often are less likely to develop
Alzheimer"s disease. Those who read a newspaper, or play chess or word games are about three times less
likely to develop the condition.
Researchers say they still do not know what causes Alzheimer"s disease. But they say these findings might
help prevent the disease in the future. |

Trees are useful to man in three very important ways: they provide him with wood and other products;
they give him shade, and they help to prevent droughts (干旱) and floods.
Unfortunately, in many parts of the world man has not realized that the third of these services is the most
important. In his eagerness (渴望) to draw quick profit from the trees, he has cut them down in large numbers,
only to find that without them he has lost the best friends he had.
Two thousand years ago a rich and powerful country cut down its trees to build warships, with which to
gain itself an empire (帝国). It gained the empire but, without its trees, its soil became hard and poor. When
the empire fell to pieces, the country found itself faced by floods and starvation.
Even though a government realizes the importance of a plentiful supply of trees, it is difficult for it to
persuade the villager to see this. The villager wants wood to cook his food with, and he can earn money by
making charcoal (木炭) or selling wood to the townsman (城市居民). He is usually too lazy or too careless
to plant and look after trees. So unless the government has a good system of control, or can educate the people,
the forests will slowly disappear.
This does not only mean that the villager"s sons and grandsons have fewer trees. The results are even more
serious. For where there are trees their roots break the soil up-allowing the rain to sink in and also hold the soil,
thus preventing it being washed away easily, but where there are no trees, the soil becomes hard and poor. The
rain falls on hard ground and flows away on the surface, causing floods and carrying away with it the rich
topsoil, in which crops grow so well. When all the topsoil is gone, nothing remains but a worthless desert. |

| [ ] |
A. tell people the use of wood
B. tell people the function of tree roots
C. warn that man mustn"t destroy forests any more
D. explain how trees help to prevent droughts and floods |
| 2. Which function of trees is the most important? |
| [ ] |
A. Giving shade to human.
B. Preventing droughts and floods.
C. Providing charcoal (木炭).
D. Offering wood to human. |
| 3. In the writer"s opinion, _____, or the forests will slowly disappear. |
| [ ] |
A. measures must be taken
B. people shouldn"t draw benefit from the trees
C. government must realize the serious results
D. unless trees are never cut down |
| 4. According to the article we know it is _____ to prevent the forests from slowly disappearing. |
| [ ] |
A. necessary but impossible
B. necessary but difficult
C. impossible and unimportant
D. difficult and impossible |
| 5. In the last two paragraphs, the writer wanted to make it clear that _____. |
| [ ] |
A. where there are no trees, the soil becomes poor but soft
B. where there are many trees, there are more floods
C. where there are no trees, the land might become desert slowly
D. floods will make the land become desert |

A quarrel at home may result in you falling ill. Don"t laugh, it"s true. Family matters including living habits
and even the way we speak have a big effect on our health, doctors say.
Wang Xiaoyu, a Senior 2 girl from Xichang, Sichuan Province, fainted (晕倒) in class when she heard
her classmates quarrel at the top of their voices. Quarrels between her parents also put the girl into a coma.
It is because she is suffering from depression (抑郁症), caused by bad relations at home, doctors explained.
"We don"t get sick or stay well by ourselves," says Dr Robert Ferrer from the US. Ferrer shows that family
forces may explain up to a quarter of health problems, in his recent research. The genes you get from your
family may cause illness. If one of your parents has a heart attack, your risk of being affected may double.
But effects on health are not only written in our DNA.
Unrelated people who live under the same roof also get similar problems. Diet, lifestyle and environment
affect our health, too. Ferrer"s research also found that if teenagers feel they are ignored or unimportant at
home they are more likely to get sick.
We may never fully understand all the effects that families have on our health. But just as individual (个别
的) problems can have effects on others, a small improvement can have big benefits, Ferrer said. |
| 1. Which of the following can best explain why Wang Xiaoyu fainted in class? |
| [ ] |
A. Because her classmates often quarreled in class.
B. Because her parents used to quarrel.
C. Because of her depression caused by bad family relations.
D. Because her classmates shouted loudly at her. |
| 2. According to Dr Ferrer, which of the following statements is TRUE? |
| [ ] |
A. We get sick or stay well by ourselves.
B. Only the genes we get from our family have a big effect on our health.
C. Our health has nothing to do with diet, lifestyle and environment.
D. Teenagers who are ignored at home get sick more easily than those who are not. |
| 3. The underlined word "coma" in Paragraph2 probably means _____. |
| [ ] |
A. surprise
B. faint
C. tiredness
D. sadness |
| 4. The best title for this passage is _____. |
| [ ] |
A. Family relations
B. The reasons why we get sick
C. Family-another cause to health
D. A research about health |
