When we can see well, we do not think about our eyes often. It is only when we can not see perfectly that we come to see how important our eyes are.

People who are nearsighted can only see things that are very close to their eyes. Many people who do a lot of close work, such as writing and reading, become nearsighted. Then they have to wear glasses in order to see distant things clearly.

People who are farsighted face just the opposite problem. They can see things that are far away, but they have difficulty reading a book unless they hold it at arm’s length. If they want to do much reading, they must get glasses too.

Other people do not see clearly because their eyes are not exactly the right shape. This, too, can be corrected by glasses. Some people’s eyes become cloudy because of cataracts. Long ago these people often became blind. Now, however, it is possible to operate on the cataracts and remove them.

When night falls, colors become fainter to the eyes and finally disappear. After your eyes have grown used to the dark, you can see better if you use the side of your eyes rather than the centers. Sometimes, after dark, you see a small thing to one side of you, which seems to disappear if you turn your head in its direction. This is because when you turn your head, you are looking? at the thing too directly. Men on guard duty sometimes think they see something moving to one side of them. When they turn to look straight at it, they can not see it any more, and they believe they were mistaken. However, this mistake happens because the center of the eye, which is very sensitive in daylight, is not as sensitive as the sides of the eye after dark.

Parties, iPods, concerts, movies, TV shows, video games, traffic. All of these things of the modern world make life entertaining and enjoyable. But our 21^st-century lifestyle is also loud and, if we don’t take notice, it can have an effect on our hearing.

Most teenagers don’t think about hearing loss. But if you experience any of the following symptoms（症状）, you may already be hearing damaged: you make efforts to hear normal talk, you have to turn up the TV or radio so high that others complain, you watch other people’s expressions to understand what they are saying, you ask people to repeat themselves, you misunderstand what people are saying or you hear ringing in your ears.

iPods and other MP3 players are as common as the clothes you wear, and just as fashionable. But if you turn up an iPod to more than 60 percent of its maximum volume（最大音量）, and listen to music for more than an hour, you are asking for trouble. And, it does not matter if the music you play is classical, rock or heavy metal.

Some researchers find that young people who break the so-called 60-percent/60-minute rule in listening to iPods are at the risk of suffering hearing loss.

Why is an iPod dangerous? With ear buds placed directly in the ear canal and high-volume music played over a long period of time, it’s like working in a loud factory all day, being a maintenance（修理）person under a jet airplane or using a jackhammer（手提钻）on a building site.

Similarly, iPod music can cause a short time or permanent（永久的）hearing damage. A loud iPod can cause a ruptured（破裂的）eardrum and, over time, may cause permanent damage to the tiny hairs in the inner ear. If these tiny hairs are damaged, they cannot effectively send sounds to the auditory nerves（听觉神经）that connect to the brain. If this happens, hearing loss becomes permanent.

1.Which of the following shows that you are suffering hearing loss?

A．You are interested to listen to others’ talking.

B．You have to read others’ expressions to understand them.

C．You can only understand others over the phone.

D．You always think you hear the ringing of the phone.

2. Which of the following is TRUE when you listen to music?

A．Listen at least an hour every time.

B．Turn up the volume to the highest level.

C．keep the sound lower than 60% of its highest volume.

D．Choose classical, rock or heavy metal music.

3.What is the correct order of causing permanent hearing loss?

a. The eardrum is broken.

b. The auditory nerves cannot receive sounds.

c. Tiny hairs are damaged.

d. Ear buds are placed directly in the ear canal.

e. High-volume music is played over a long time.

A．d-a-c-b-e          B．e-c-a-b-d          C．b-c-a-d-e          D．d-e-a-c-b

4.This passage is mainly about      .

A．music that teenagers like                 B．hearing problems caused by the loud world

C．ways that teenagers enjoy music            D．dangerous modern lifestyles of teenagers.

 

When you turn on the radio, you hear an advertisement. When you watch television, you hear and see an advertisement. If you turn the pages of a newspaper or magazine, again you find an advertisement. If you walk down the street, you see one advertising board after another. All day, every day, people who want to sell you something compete to catch your attention. As a result, advertisements are almost everywhere.

In the West, advertisements are the fuel that makes mass media work. Many TV stations, newspapers, magazines, radio stations are privately owned. The government does not give them money. So where does the money come from? From advertisements. Without advertisements, there would not be these private businesses.

Have you ever asked yourself what advertising is? Through the years, people have given different answers to the question. For some time it was felt that advertising was a means of “keeping your name before the public”. And some people thought that advertising was “truth well told”. Now more and more people describe it in this way: Advertising is the paid , nonpersonal, and usually persuasive description of goods, services and ideas by identified sponsors(出资者) through various media.

First, advertising is usually paid for. Various sponsors pay for the advertisements we see, read, and hear over the various media. Second, advertising is nonpersonal. It is not face to face communication. Although you may feel that a message in a certain advertisement is aimed directly at you. In reality, it is directed at large groups of people. Third, advertising is usually persuasive. Directly or indirectly it tells people to do something. All advertisements try to make people believe that the product, idea, or service advertised can do good to them. Fourth, the sponsor of the advertisement must be identified. From the advertisement, we can see if the sponsor is a company, or an organization, or an individual. Fifth, advertising reaches us through traditional and nontraditional mass media. Included in the traditional media are newspapers, magazines, radio, television, and films. Nontraditional media includes the mail, matchbox covers and billboards.

2.The existence of the privately owned mass media depends financially on______.

D. the audience

3.Which of the following is considered nontraditional mass media?

4.According to the passage, which of the following statements about the features of advertisements is NOT true?

B. Advertising is meant for large groups of people.

C. Advertising tells people to do something directly or indirectly.
