Are some people born clever, and others born stupid? Or is intelligence (智力) developed by our environment and our experience? Strangely enough, the answer to these questions is yes. In some degree, our intelligence is given to us at birth, and no education can make a genius (天才) out of a child born with low intelligence. On the other hand, a child who lives in a boring environment will develop his intelligence less than one who lives in rich environment. Therefore, the limits of person’s intelligence are fixed at birth, whether or not he reaches those limits will depend on his environment. This point of view, now is held by most experts.
It is easy to show that intelligence is something that we are born with. The closer the blood relationship between two people, the closer they are likely to be intelligence. If we take two strangers by chance from the population, it seems that their degree of intelligence will be completely different. If, on the other hand, we compare two twins, they will very likely be as intelligent as each other. Relations like brothers and sisters, parents and children, usually have similar intelligence, and this clearly suggests that intelligence depends on birth.
Imagine now that we take two twins and put them in different environments. We might send one, for example, to a university and the other to a factory separately where the work is boring. We would soon find differences in intelligence developing, and this shows that environment as well as birth plays an important role. This conclusion is also suggested by the fact that people who live in close contact (接觸) with each other, but who are not related at all are likely to have similar degree of intelligence.
小題1:How is man’s intelligence given?

A．At birth	B．Through education
C．Both at birth and through education	D．Neither at birth nor through education

小題2:What does the underlined word mean in the first paragraph?

A．穩固

小題3:According the passage, if a child is born with low intelligence, what might happen to him later?

A．Become a genius.

B．Still become a genius if he should be given special education.

C．Reach his intelligence limits in rich environment.

D．Never reach his intelligence in his life.

小題4:What can we learn from the example of the twins going to a university and to a factory?

A．The importance of their intelligence.

B．The role of environment on intelligence.

C．The importance of their jobs

D．The part that birth plays

小題5:What statement is TRUE according to the passage?

A．No education can help make a genius.

B．Personality is important as intelligence which was given to people at birth.

C．People who have similar degree of intelligence must be relatives.

D．Environment influences people in intelligence developing.

Carbon monoxide poisoning (一氧化碳中毒) causes death and injuries around the world. This gas is a problem in all parts of the world that experience cold weather. A few years ago, America’s Centers for Disease Control (C. D. C.) studied deaths linked (聯系) with carbon monoxide poisoning. It found that the number of carbon monoxide deaths in the United States was greatest in January. The C.D.C. also found that carbon monoxide kills more than four hundred Americans each year. And, it said more than twenty thousand people are taken to hospital for treatment of health problems linked with the gas.
Carbon monoxide is called the silent killer because people do not know it is in the air. The gas has no color, no taste and no smell. It does not cause burning eyes. And it does not cause people to cough. Yet, carbon monoxide gas is very deadly (致命的). It steals the body’s ability to use oxygen.
Carbon monoxide makes it difficult for the blood to carry oxygen to body tissues (血管). It does this by linking with the blood. When the gas links with the blood, the blood is no longer able to carry oxygen to the tissues that need it. Damage (損害) to the body can begin very quickly from large amounts (數量) of carbon monoxide.
How quickly this can happen depend on how long a person is breathing the gas and how much gas he or she breathes in.
Carbon monoxide poisoning has warning signs(標志). But people have to be awake to realize them. Small amounts of the gas will cause a person’s head to hurt. He or she may begin to feel tired. Their stomachs may feel sick. The room may appear to be turning around. The person may have trouble thinking clearly.
People develop serious headache as the amount of the gas continues to enter their blood. They will begin to feel very tired and sleepy. They may have terrible stomachache.
Doctors say carbon monoxide influences people differently. For example a small child will experience health problems or die much sooner than an adult. The general health of the person or his or her age can also be important.
小題1:The damage of carbon monoxide to the body has something to do with _____.

A．the amount a person breathes in

B．whether a person is healthy

C．how many signs a person finds

D．ages of people

小題2:One of the signs of carbon monoxide poisoning is _____.

A．burning eyes	B．bad cough
C．serious headache	D．high fever

小題3:Which of the following is TRUE according to the passage?

A．Carbon monoxide poisoning seldom happens in cold areas.

B．Twenty thousand Americans are killed by carbon monoxide each year.

C．Most people know whether there is carbon monoxide in the air.

D．Carbon monoxide stops the blood from carrying oxygen to body tissues.

小題4:What does the passage mainly talk about?

A．Warning signs that carbon monoxide poisoning has.

B．Reasons why carbon monoxide can cause person’s death.

C．The damage of carbon monoxide and how it works.

D．Influences of carbon monoxide on children and adults.

The world itself is becoming much smaller by using modern traffic and modern communication. Life today is much easier than it was hundreds of years ago, but it has brought new problems. One of the biggest problems is pollution.
To pollute means to make things unfit or unclean to use. Pollution comes in many ways. We see it, smell it, drink it and even eat it. Pollution is beginning to threaten (威脅) our health, our happiness and our life.
Man has been polluting the earth from the time he first made fire, washed his clothes in the river and threw his waste on the ground. When land was used up or water became dirty, men moved on to another place. At first, the problem was not so serious because there was plenty of clean air, land and water. There weren’t so many people then and their wants fewer. All the dirty things could be absorbed(吸收) by nature and soon covered over. But this is no longer true. The increase of pollution and the development of industry(工業) have changed that. Man is slowly poisoning(毒害)not only his environment but also himself.
Through the use of poison, man has polluted the land, killing the animals. By putting dirty water and chemicals into rivers and lakes we have polluted our drinking water, killing the fish.
Our increasing population is part of the problem. More people, more waste.
Where is this all to end? Are we turning the world into a big rubbish dump(堆存處)，or is there any hope that we can get rid of (擺脫，除去) the pollution? Luckily, millions of people have been warned of the danger of pollution. Large numbers of people are now working hard to bring pollution under control.
The earth is our home. We must take care of it. This means keeping the land, air and water clean. And we must take care of the rise in pollution at the same time.
小題1:Which of the following is NOT true according to the passage?

A．We live on the earth, so we should look after it.

B．Man is fighting against different kinds of pollution.

C．To pollute means to make air, water and land unfit for use.

D．All the waste produced by modern industry can be absorbed.

小題2:In Paragraph4, the underlined word “chemicals” mean ____________.

A．化學物質

B．醫療器械

C．污染源

D．塑料制品

小題3:Through the uncontrolled use of poison man has___________.

A．made the drinking water dirty	B．polluted the land
C．killed the animals	D．all of the above

小題4:From the sentences “More people, more waste.” We know that ___________

A．we need more people, not more waste

B．the increase of population caused more waste.

C．there isn’t any hope that we can get rid of the pollution

D．More people have been warned of the danger of more waste.

小題5:Which of the following is TRUE according to the passage?

A．Man begins to understand the pollution.

B．Man doesn’t know how to control pollution.

C．Man is doing something to control pollution.

D．Man still doesn’t realize how serious pollution is.

People are busy working every day, so they do not have enough time to do exercises. As a result, many people become too fat or too thin. To keep our bodies healthy, we have to do exercises every day.
There are many kinds of exercises. Bending (彎腰) and stretching (伸展) helps us move easily. Before we play ball games or swim, it is better for us to do bending and stretching exercises first. This kind of exercise is sometimes called warm-up exercise. Running is also a good exercise. If we cannot run fast, we can Jog. Jogging means running slowly. Again, before we run or jog, we must do warm-up exercises. Also, we should not run or jog in busy streets. The air there is often dirty. Some people like weight lifting (舉重)because it can make their bodies strong. Also, we need to do some warm-up exercises before weight lifting.
