Unless action is taken immediately, there is a good chance that all the oceans of the world will be dead by the year 2010.How can this possibly happen??

We have already seen that people allow all sorts of waste products to flow into the sea. It is almost impossible to measure how much waste water and industrial waste end up in our oceans, but we can find out how much oil is poured into them legally and illegally. It is illegal to pour oil into the sea close to the shore, but when a ship is many miles out to sea there are no such rules. Scientists have different ideas as to the amount of oil put into the sea, but the lowest figure for oil poured in European waters alone is nearly 200 000 tons every year. Some people say the figure could be ten times as high.?

It is not only our coasts that suffer from oil pollution. Among other things, many shell fish(creatures which live in water),and have a hard shell—oysters and mussels, for example—now have high amounts of poisonous substances. Next time you have shell fish to eat, how can you be sure that they are free from oil pollution? You cannot see the effects and you cannot taste them, either. It is really quite a problem.?

This passage is mainly about_______.?

A. pollution in the oceans

B. the amounts of oil in the sea?

C. the amounts of poison in shell fish

D. oil pollution in the waters?

According to the passage, what is the main cause of oil pollution??

A. Oil ships which meet and strike each other.?

B. Oil poured at sea when the oil tanks are cleaned out.?

C. Oil coming out of the bottom of the sea.?

D. Oil from waste water and industrial waste.?

Which of the following is illegal?

A. Pouring oil into the sea from land, especially when there is no other choice.

B. Allowing waste materials to flow into the waters.?

C. Pouring oil at seaside.?

D. Going fishing when the water is polluted by oil.?

A high school history teacher once told us, “If you make one close friend in school, you will be most fortunate. A   21   friend is someone who stays with you for life”.   22   teaches that he was right. Good friendship is just not easily   23  .

For some people, many friendships on the surface are   29   enough. And that’s all right. But at some   30   we need to make sure that our expectations are the same as our friends’ expectations. The sharing of personal experience including our tears as well as our dark   31   is the surest way to deepen friendships. But it must   32   slowly and carried on only if there are   33   of interest and action in return.

What are some of the   34   of our friendship? The greatest is to   35   too

much too soon. Deep relationships   36   time. Another “major difficulty” is the selfishness to think one “possesses” the other, including his time and attention.   37  , friendships require actions in return. In other words, you must   38   as much as you take. Finally there is a question of taking care of. Unless you spend   39   time together, talking on the phone, writing letters, doing things together, friendships will die   40   .

Lucky is the man who has no “skeleton in his closet”. When a man has done something in his life that he is ashamed of, that he wants to hide, he is said to have a “skeleton in his closet”. Some people may have more than one skeleton.

As we have noted many times, it is hard to find out how these expressions begin. Sometimes, we get some hard facts. But more often we have to depend on guesswork. And that is true of this phrase, which came from England.

Before 1932, English law did not permit a doctor to cut open a dead human body for scientific examination, unless it was the corpse(尸體) of an executed(處決) criminal.

But when it became legal, more and more doctors demanded skeletons for a more scientific study of medicine. It was helping in the advance of modern medicine. The demand had become so strong that men began to rob tombs and sell skeletons to doctors at high prices.

We are told that a doctor would usually buy just one skeleton for scientific study. It became very important in his work. But he had to keep it hidden because most people objected to keeping such a thing. As a rule, the doctor would keep his skeleton in some dark corner where it could not be seen, or hide it in a closet.

After a time, people began to suspect(懷疑) every doctor of hiding a skeleton in the closet. From this suspicion, the phrase “a skeleton in the closet” took on a broader, more general meaning to describe anything that a man wanted to keep others from discovering. It could be proof of a criminal act, or something much less serious. Well, that is one theory.

One writer, however, believes that the phrase might have come from something that really happened. It is his guess that a hidden closet in some old English country home may have turned up a real skeleton, clear proof of some old family shame or crime. Well, one man’s guess is as good as another. But this sounds like a story by the great French novelist, Balzac.

Baizac tells us of a man who suspected his wife of having a lover. The husband comes home by surprise. But she hears him and quickly hides her lover in the closet of her bedroom. He enters her room and asks her if she is hiding her lover. He says he will not open the door to the closet if she promises him there is no one there; He will believe her. She answers firmly that she is not hiding anyone in the closet.

The husband then begins to build a solid brick wall against the closet. His wife watches, knowing that her lover will never come out alive. But she will not change her story and admit her guilt.   

1. Which of the following situations is suitable for using the phrase “skeleton in the closet” ?

A. You have stolen something precious and don’t want it discovered.

B. You are a doctor and have to keep a skeleton for research.

C. If you have cut open a dead human body for scientific examination you should keep the skeleton secret.

D. You have done a crime or done something foolish, but you want to keep other from discovering it.

2. From the text we know that there are _______ theories about how the phrase “skeleton in the closet” came into being.

A. one    B. two    C. three  D. four

3. In Chinese the world “skeleton” means _______.

A. 尸體   B. 標(biāo)本  C. 收藏  D. 骷髏

4. Which of the following is right according to the text?

A. In the 20th century, doctors realized the importance of anatomy(解剖) in the development of medicine.

B. The doctors of the ancient times liked to collect as many skeleton as possible.

C. The thieves stole skeletons from tombs in order to help the doctors.

D. It was legal that corpses of anybody were cut open for scientific examination in history.

5. From the story Balzac told we know that the wife’s lover must have become _______.

A. a corpse  B. a phrase  C. a skeleton  D. a secret

The whole body is covered with skin.The surface of the skin is dead(like the hair and the nails),but it is made from a living layer(層)just under the surface.The outside dead layers wear off(磨損)all the time,with new ones replacing them,and the body forms a totally new skin every three weeks.
The skin protects the body from the outside world and it passes information from the outside.It helps to keep water in the body and to keep the body at the same temperature.Becteria(細菌)can’t get in through the skin unless it is damaged.
If the weather is cold,the blood vessels(血管)in the skin squeeze down,or contract(收縮),so that as little blood as possible comes near the surface.This means that less warmth is lost to the outside.This makes the skin look pale,or even “blue”.At the same time,the hairs on the skin are pulled upright by tiny muscles.
When it is hot,the blood vessels expand(擴大),or get wider again,to allow plenty of blood to run near the surface of the skin.This helps the body to lose heat,and the skin may look red.At the same time,the sweat glands(汗腺)produce more sweat,which cools the skin.
If your skin has ever been numb(麻木的),you will realize how important the feeling from the skin is.Nerves(神經(jīng))in the skin are sensitive(敏感的)to heat and cold,sharpness,hardness and softness,wetness and dryness and pain.If one is not able to feel these things,which can act as warnings,he is likely to be burned,cut or hurt in other ways.
The colour of the skin depends on special colour cells(細胞).These are just below the top layers of the skin.They are needed as protection from some harmful ray of the sun.The stronger the sun is,the more important it is to have a dark skin.People with pale skins may “tan”(曬黑)in the sun.This happens when the body produces extra colour cells in the skin for protection.In the sun,the skin produces a vitamin(vitamin D)which is needed for strong bones.
【小題1】Which of the following statements is NOT true?

A.Our hair and nails are dead like the surface of the skin.
B.There is skin all over our body.
C.The skin of our bodies will be completely different in three weeks.
D.The surface of the skin is made of a living layer.
【小題2】The second paragraph mainly tells us about______.
A.the functions of the skin
B.the information from the outside
C.the water in the body
D.the temperature of the body
【小題3】Bacteria will get in through the skin______.
A.when one’s skin is numb
B.when one is ill
C.when the skin is cut
D.when the sweat glands produce more sweat
【小題4】When the weather is cold,the skin will contract in order to______.
A.a(chǎn)llow more blood nearB.make the skin look blue
C.keep warmthD.help the body lose heat
【小題5】The colour of the skin is determined by______.
A.the rays of the strong sunB.colour cells
C.top layers of the skin D.vitamin D
