As a result of pollution, Lake Erie, on the borders of the USA and Canada, is now without any living things.
Pollution in water is not simply a matter of “poisons” killing large numbers of fish overnight, Very often the effects of pollution are not noticed for many months or years because the first organisms（生物体）to be affected are either plants or plankton(浮游生物). But these organisms are the food of fish and birds and other creatures. When this food disappears, the fish and birds die too. In this way a whole food chain can be wiped out, and it’s not until dead fish and water birds are seen at the river’s edge or on the seashore that people realize what is happening.
　　Where do the substances which pollute the water come from? There are two main sources of sewage（下水道污物）and industrial waste. As more detergent（洗涤剂）is used in the home, so more of it is finally put into our rivers, lakes and seas. Detergents harm water birds, dissolving the natural substances which keep their feathers water-proof (防水). Sewage itself, if not properly treated, makes the water dirty and prevents all forms of life in rivers and the sea from receiving the oxygen they need. Industrial waste is even more harmful as there are many highly poisonous things in it, such as copper and lead.
　　So, if we want to stop this pollution, the answer is simple: sewage and industrial waste must be made clear before flowing into the water. It may already be too late to save some rivers and lakes, but others can still be saved if the correct action is taken at once.
70. Pollution of water is noticed________.
　　A. when the first organisms are affected　
B. when a good many fish and birds die
　　C. when poisonous things are poured into water　
D. as soon as the balance of nature is destroyed

PART THREE READING COMPREHENSION
Directions: Read the following three passages. Each passage is followed by several questions or unfinished statements. For each of them there are 4 choices marked A,B,C and D. Choose the one that fits best according to the information given in the passage. (20%)
A
“Mummy, I don’t know what to play with. ” Steve interrupts his mother, who is talking to a friend, for the fourth time. “You’ve got a room full of toys!” his mother says, impatiently, In fact it is the jumble of toys which is to blame for four -year-old Steve's lack of interest in his dolls, cars and stuffed （packed）animals. Each morning he tips out three washing baskets of toys all over his floor, listlessly pulls out something and shortly after is standing at his mother’s desk or following her into the kitchen saying: “Mummy, I am bored.”
A family therapist（治疗专家）explains why children lose interest when they have a whole “toy shop” at home : “According to their brain development, little children are not in a position to judge the quality of a variety of things at once. There is always just one favorite toy for the moment. All the rest is left lying about.” What can parents do to stop their children from being oversupplied with toys? Under no conditions simply make something disappear without the child’s knowledge. If he/she takes no more notice of a toy, a parent can ask if it can be stored or given away. Be warned though the child will help. Lyn is the mother of four-year-old Jessie, and holds the toys and books that are the current（at present）favorites. When it seems to her that her daughter is tired from a cupboard in another room. The box of “old” toys goes into the cupboard. When her child says she is “bored”, they also get something from her cupboard—it may be something she has had for some time but because she hasn’t seen it for a while it is almost like a new toy.
　　Some favorite toys stay out all the time, and there is collection of dolls which sits in the comer, but in this way Lyn has found that she has fewer toys to put away at the end of the day and her daughter always has something “fresh” to play with.

On Anger
Doctors say anger can be an extremely harmful emotion, unless you learn how to deal with it. They warn that angry feelings can lead to heart disease, stomach problem, headaches, emotional problems and possibly cancer.
Anger is a normal emotion that we all feel from time to time. Some people express anger openly in a calm reasonable way. Others burst with anger, losing control of themselves. But other people repress their anger. They cannot or will not express it.
For years many doctors thought that repressing anger was more dangerous to a person’s health than expressing it. They said that when a person is angry, the brain releases the same hormones (激素) that are produced during tense situations. They speed the heart rate, raise blood pressure, or sugar into the blood and narrow the blood vessels to the interstices (空隙). In general, the person feels excited and ready to act.
Doctors said that repressing these feelings only makes the feelings continue. And this can lead to many medical problems. Doctors thought a person could prevent these problems by letting the anger out by expressing it freely. But recently some doctors held a different view. They said that people who express anger repeatedly and violently did become, in fact, more and not less angry. They said this, too, can cause medical problems.
Some doctors say that both repressing and expressing anger can be dangerous. They believe that those who express anger strongly may be more likely to develop heart disease, and they believe that those who keep their anger inside may face a greater danger of high blood pressure.
Doctors say the solution is learning how to deal with anger. They say the first step is to admit that you are angry and to recognize the real cause of the anger, then decide if the cause is serious, enough to get angry about. If it is, they say, “Do not express your anger while angry. Wait until your anger has cooled down and you are able to express yourself calmly and reasonably.”

C
The journey two divers made some time ago to the deepest point on the earth makes us realize how much of the world still remains to be studied. The two men went down seven miles to the bottom of the Pacific Ocean inside a small steel ball to find out if there are any ocean currents(水流) or signs of life.
It was necessary to set out early, so that the ball would come to the surface in daylight, and be easily found by the mother ship which would be waiting for it. The divers began preparations early in the morning and soon afterwards, when all was ready, the steel ball disappeared under the surface of the water.
The divers felt as if they were going down steps as they passed through warm and cold layers (层) of water. In time the temperature dropped to the freezing point. They kept in touch with the mother ship by telephone telling how they felt. Then, at a depth of 3,000 feet, the telephone stopped working and they were quite cut off from the outside world. All went well until some four hours later at 30,000 feet, the men were frightened by a loud, cracking noise. Even the smallest hole in the ball would have meant instant death. Luckily, though, it was only one of the outer windows that had broken. Soon afterwards, the ball touched the soft ocean floor raising a big cloud of "dust" made up of small dead sea creatures. Here, powerful lights lit up the dark water and the men were surprised to see fish swimming just above them quite untroubled by the great water pressure. But they did not dare to leave the lights on for long, as the heat from them made the water boil. Quite unexpectedly, the telephone began working again and the faint but clear voices of the divers were heard on the mother ship seven miles away. After a stay of thirty minutes the men began their journey up, arriving three hours later, cold and wet through, but none was worse for their experience.

B
I went over my grandmother’s house today and she didn’t have time for me. You see, the lady’s husband downstairs died and my Grandmother wanted to make some cookies for her. My grandmother did not analyze (分析) how the lady treated her, or if the lady needed any cookies, or even if the lady would like the cookies. She didn’t think how much the lady has done for her. She simply began baking.
My Grandmother turned 94 last week and this I believe is her secret to life. My grandmother is generous (慷慨) and hard-working in a way that is rare for our time. She lives by a simple belief: if someone needs your help, you help. Never mind all the analyzing and thinking whether the person deserves or appreciates the help. My grandmother doesn’t sit around thinking about who might be making use of her: she simply does what is needed.
At 94, she is busy in life. She is making a blanket for a new great grandchild, and worried that I don’t have enough kitchen towels for my home. She is bringing soup to a sick neighbor, and teaching the new wife of her cousin (who is 88) how to cook Italian food.
My grandmother had every right to give up, but she didn’t — and amazingly life did bring her good things, like a husband with twinkling blue eyes who was much ahead of his time and believed that men should do an equal amount of cooking and cleaning in the home, three beautiful children (my father and two aunts), 22 grandchildren, and five great grandchildren. My grandmother is not afraid to give someone she barely knows a bowl of soup. She never keeps herself out of the world.

62. In the writer’s opinion, ________.
A. my grandmother has a secret way of living
B. my grandmother does everything on careful consideration

A. My grandmother cares for her children even some strangers.
B. My grandfather does not treat women in an unfair way.
C. This is a family in which there are nearly 30 people now.
