Many views are held as to whether or not sharks will attack man. Some people believe that a shark will attack man only when he is near the shark in the wa-ter. Others take the position (见解）that sharks never attack man. The facts show that the truth is between these two positions.
There are thirty-two kinds of sharks, and only three are dangerous to man. These are the hammer head shark, the tiger shark, and the white shark. All sharks are easily frightened and are much more afraid of man than man afraid of them. They have a keen(敏锐的）sense of smell even from a place that is a fairly long way away. The smell of blood excites them, then they may attack human beings.
If such an attack does take place，however , it is done blindly because the shark
happens to be excited by the smell of blood. This is very different from the manner in which a lion or a tiger will attack its victim(受害者）in the woods. The one acts without thinking while the other acts with the greatest care. What is the best title of the passage?

Moods, say the experts, are feelings that tend to become fixed, influencing one’s outlook for hours, days or even weeks. That’s great if your mood is a pleasant one, but a problem if you are sad, anxious, angry or simply lonely.
Perhaps the best way to deal with such moods is to talk them out; sometimes, though, there is no one to listen. Modern pharmacology（药理学）offers a lot of tranquilizers（镇静剂）What many people don’t realize, however, is that scientists have discovered the effectiveness of several non-drug methods to set you loose from an unwanted mood. These can be just as useful as drugs, and have the added benefit of being nonpoisonous. So next time you feel out of sorts, don’t head for the drug-store but try the following methods.
Of all the mood-altering self-help techniques, aerobic exercise seems to be the most efficient cure for a bad mood. “If you could keep up the exercise, you’d be in high spirits, ” says Kathryn Lance, author of Running for Health and Beauty.
Researchers have explained biochemical and various other changes that make exercise compare favourably to drugs as a mood raiser. Physical exertion such as housework, however, does little. The key is aerobic exercise—running, cycling, walking, swimming or other repetitive and sustained activities that increase the heart rate, increase blood circulation and improve the body’s use of oxygen. Do some of the activities for at least 20 minutes a session three to five times a week.What is the main subject discussed in the passage?
| A．How to beat a bad mood. | B．How to talk bad moods out. |
| C．How to do physical exercises. | D．How to join in aerobic exercises. |
According to the passage, all of the statements are true EXCEPT that
| A．climbing is an efficient cure for a bad mood |
| B．moods can have a bad effect on people’s health |
| C．aerobic exercise can help people get rid of bad moods |
| D．pharmacology has provided people with many tranquilizers |
“Feel out of sorts” in paragraph 2 could best be replaced by “ ”
| A．put things in order | B．are in high spirits |
| C．are in a bad mood | D．search for tranquilizers |
It can be inferred from the passage that
| A．some drugs are more effective than physical exercises |
| B．a person does not need aerobic exercise if he is in a good mood |
| C．the best way to overcome a bad mood is to talk to oneself |
| D．when in a bad mood, one may not work very efficiently |
Our sense of smell, which we normally take for granted, is nowadays being increasingly used for purposes which might surprise us if we realized them.
One area in which smells are created to achieve particular results is marketing. For some time producers have taken advantage of our sense of smell with regard to household goods.
When pleasant smells are passed through a store’s air conditioning system, people tend to spend more time in the store and buy more. For example, the smell of chocolate is used in sweet stores, while the smell of leather and perfume are used in clothes stores.
In a test, people looked at the same types of shoes in two rooms—one filled with purified air, the other with a smell of mixed flowers. Eighty-four percent of the people preferred the shoes in the room with the smell of flowers. In fact, many said they would have paid up to US $ 10 more for a pair.
Smells also have other uses. Research has shown that certain smells can help to calm anxious people and increase their feeling of safety. Smells such as that of flowers and pine forests might therefore be used to relax patients in doctors’ and dentists’ waiting rooms, and to make the environment more pleasant and less stressful to them.
Some companies are experimenting with different smells to produce different efferent effects on their workers according to the time of day.
For example, early in the morning they might put the smell of lemon in the air conditioning system to wake people up. In the middle of the morning, when the atmosphere tends to become more tense, the smell of wood could be used to calm people down. Before lunchtime the smell of melting butter would encourage people to go to lunch on time. After lunch, when people often begin to lose attention, the smell of mint would increase their watchfulness.
While some of these uses of smells may e helpful and effective, not everyone would agree with their use to control customers in stores. It has been suggested by consumers’ organizations that one way to avoid this new subconscious（无意识）pressure to buy is to go shopping when people are less likely to be influenced by smells.We can conclude from the text that
| A．smells are widely used in different shops | B．different smells can keep people feel happy |
| C．smells are effective if used in suitable cases | D．hospitals take advantages of the sense of smell |

The food we eat seems to have a great effect on our health. Although science has made big steps in making food more fit to eat, it has, at the same time, made many foods unfit to eat. Some research has shown that perhaps eighty percent of human illness is related to food and forty percent of cancer is related to food as well. That food is related to illness is not a new discovery. In 1945, some researchers realized that things commonly used to keep colour in meats and other food additives（添加剂）caused cancer.
Yet, these additives remain in our food, and it is difficult to know which things on the wrappings（包装）of foods are helpful or harmful. The additives which we eat are not all so direct. Farmers often give penicillin to their animals, and because of this, penicillin has been found in the milk of cows. Sometimes similar tings are supplied to animals not for their health, but just to make a profit.
The farmers are simply trying to fatten the animals in order to get a higher price on the market. Although some countries have tried to control such things, the practice continues.
