Maybe ten-year-old Elizabeth put it best when she said to her father, "But, Dad, you can't be healthy if you're dead."

Dad, in a hurry to get home before dark so he could go for a run, had forgotten to wear his safety belt— a mistake 75% of the US population make every day. The big question is why.

There have been many myths about safety belts ever since their first appearance in cars some forty years ago. The following are three of the most common.

Myth Number One: It's best to be "thrown clear" of a serious accident.

Truth: Sorry, but any accident serious enough to "throw you clear" is also going to be serious enough to give you a very bad landing. And chances are you'll have traveled through a windshield(挡风玻璃) or door to do it. Studies show that chances of dying  after a car accident are twenty-five times greater in cases where people are "thrown clear".

Myth Number Two: Safety belts "trap" people in cars that are burning or sinking in water.

Truth: Sorry again, but studies show that people knocked unconscious due to not wearing safety belts have a greater chance of dying in these accidents. People wearing safety belts are usually protected to the point of having a clear head to free themselves from such dangerous situations, not to be trapped in them.

Myth Number Three: Safety belts aren't needed at speeds of less than 30 miles per hour (mph).

Truth: When two cars traveling at 30 mph hit each other, an unbelted driver would meet the windshield with a force equal to diving headfirst into the ground from a height of 10 meters.

       Silence is unnatural to man. He begins life with a cry and ends it in stillness. In between he does all he can to make a noise in the world, and he fears silence more than anything else. Even his conversation is an attempt to prevent a fearful silence. If he is introduced to another person, and a number of pauses occur in the conversation, he regards himself as a failure, a worthless person, and is full of envy of the emptiest-headed chatterbox (喋喋不休的人). He knows that ninety-nine percent of human conversation means no more than the buzzing of a fly, but he is anxious to join in the buzz and to prove that he is a man and not a waxwork figure (蜡塑人像).

       The aim of conversation is not, for the most part, to communicate ideas; it is to keep up the buzzing sound. There are, it must be admitted, different qualities of buzz; there is even a buzz that is as annoying as the continuous noise made by a mosquito. But at a dinner party one would rather be a mosquito than a quiet person. Most buzzing, fortunately, is pleasant to the ear, and some of it is pleasant even to the mind. He would be a foolish man if he waited until he had a wise thought to take part in the buzzing with his neighbors.

       Those who hate to pick up the weather as a conversational opening seem to me not to know the reason why human beings wish to talk. Very few human beings join in a conversation in the hope of learning anything new. Some of them are satisfied if they are only allowed to go on making a noise into other people's ears, though they have nothing to tell them except that they have seen two or three new plays or that they had food in a Swiss hotel. At the end of an evening during which they have said nothing meaningful for a long time, they just prove themselves to be successful conversationists.

       Holiday Inns and McDonald's, both saw unmatched growth in the 1960s. Their growth opened another direct business operation — franchising (特许经营).

These operations have the same general pattern. The franchisor, the parent company, first establishes a successful retail business. As it expands, it sees a profit potential in offering others the right to open similar business under its name. The parent company's methods and means of identification with consumers are included in this right. The parent company supplies skill, and may build and rent stores to franchisees. For these advantages the franchisee pays the franchisor a considerable fee. However, some of the advantages and disadvantages are different.

       By extending a "proven" marketing method, a parent can profit in several ways. First, the franchisee's purchase price gives the parent an immediate return on the plan. Then the sale of supplies to the franchisee provides a continuing source of profits. As new businesses are added and the company's reputation spreads, the value of the franchise increases and sales of franchises become easier. The snowballing effect can be dramatic. Such growth, too, brings into play the economies of scale (规模经济). Regional or national advertising that might be financially impossible for a franchisor with 20 franchises could be profitable for one with 40.

       The parent, then, finds immediate gains from the opportunity to expand markets on the basis of reputation alone, without having to put up capital or take the risk of owning retail stores. Added to this advantage is a less obvious but material one. Skilled, responsible retail managers are rare. People who invest their capital in franchises, though, probably come closer to the ideal than do paid managers. In fact, the franchisee is an independent store operator working for the franchisor, but without an independent's freedom to drop supplies at will. Of course the factory's costs of selling supplies are less. But also certainly the franchisee buying goods that have had broad consumer acceptance will not casually change supplies, even when the contract permits. If the hamburger is not what the customer expected, they may not return. Having paid for the goodwill, the franchisee won't thoughtlessly destroy it.

       Franchising may give you the idea that as a franchisor, you need only relax in the rocking chair.

       Franchising, however, has problems to be solved.

       The evidence for harmony may not be obvious in some families. But it seems that four out of five young people now get on with their parents, which is the opposite of the popularly-held image of unhappy teenagers locked in their room after endless family quarrels.

       An important new study into teenage attitudes surprisingly shows that their family life is more harmonious than it has ever been in the past. "We were surprised by just how positive today's young people seem to be about their families," said one member of the research team. "They're expected to be rebellious (桀骜不驯) and selfish but actually they have other things on their minds: they want a car and material goods, and they worry about whether school is serving them well. There's more negotiation and discussion between parents and children, and children expect to take part in the family decision-making process. They don't want to rock the boat." So it seems that this generation of parents is much more likely than parents of 30 years ago to treat their children as friends. "My parents are happy to discuss things with me and willing to listen to me," says 17-year-old Daniel Lazall. "I always tell them when I'm going out clubbing. As long as they know what I'm doing, they're fine with it." Susan Crome, who is now 21, agrees. "Looking back on the last 10 years, there was a lot of what you could call negotiation. For example, as long as I'd done all my homework, I could go out on a Saturday night. But I think my grandparents were a lot stricter with my parents than that."

       Maybe this positive view of family life should not be unexpected. It is possible that the idea of teenage rebellion is not rooted in real facts. A researcher comments, "Our surprise that teenagers say they get along well with their parents comes because of a brief period in our social history when teenagers were regarded as different beings. But that idea of rebelling and breaking away from their parents really only happened during that one time in the 1960s when everyone rebelled. The normal situation throughout history has been a smooth change from helping out with the family business to taking it over."

       Music is an international language that is beautiful to people all over the world. It seems to be a natural need for us.

       Music plays a significant role in education. Studies have indicated that music physically develops the part of the brain known to be involved with language. Therefore the development of one promotes the growth of the other, and musical training not only develops a child's language skills but also promotes the learning of a second language. Music also causes improvement in brainpower. The thought patterns that are formed while studying music may help improve the ability to learn other subjects.

        First, music is beneficial with its ability to reduce stress. And stress is associated with many illnesses, which can be prevented with stress reduced. When people are very stressed, there is a tendency to avoid listening to music. But as we know, productivity increases when stress is   reduced.

       Additionally, music can have positive influence on mood, and many people will turn to certain songs to improve their moods. The main reason behind this phenomenon is that music has the ability to express one's feelings better than any other medium. It also increases self-confidence.

A. So how does it help us?

B. The two are so closely related.

C. Let's see how people enjoy music.

D. Perhaps it feels like a waste of time.

E. The key is to choose the right type of music.

F. Music has some sort of psychological effect.

G. Good music also makes us remember the moments when we were happy.

       In order to encourage students take outdoor activities, our school organized a mountain-climbing activity at July 10th. Hundreds of us took the part in it. It was a nice day. At 8:00, we gathered at the foot of Jinyun Mountain to set out for the top in high spirits. Along the way, we chatted, sang and laugh, enjoying the fresh air and beautiful sceneries. When some students fell behind, other would come and offer help. About 2 hours late, we all reached the top. Bathing in the sunshine, the distant city looked fantastic but we jumped and cheered with joy.

       This activity benefited us a lot. Not only did it get us close to nature and give us relaxation from heavy homework, but it also promoted friendship among us. What wonderful a trip it was!
