The world has many beautiful sounds. We can hear the songs of birds and the laugh of people. We can listen to the cool music and news reports. And it’s all because of our ears! They bring us a world of sounds. But some people can’t hear any sound at all. Some are born deaf. Others can hear well in their childhood, but too many loud sounds hurt their ears later on. Many people in China can’t hear ordinary sounds clearly. A large number of them are children. Most of them are born with good hearing. But six children of every 1,000 have hearing problems when they are born. And if a child has hearing problems, he or she usually will also have some learning problems at school. A lot of things can cause hearing problems. For example, too much earwax is not good for our hearing. And noise louder than 85 decibels (分贝) can hurt our ears and make us lose our hearing for a short time or even for ever. Hearing is important for all of us. So we should do our best to give our ears special care. Don’t forget to do the following: ● Try to stay away from places with too much noise. If you have to go, wear earplugs. A pair of good earplugs can cut the noise by 30 decibels. ● When swimming, remember to put earplugs into your ears to stop water from getting in. ● Never put anything sharp into your ears. If you think you have too much earwax, ask your mum or dad to help you clean it out. Keep these things in mind! Then you won’t be saying “WHAT? WHAT?” when you are older. 小题1:What does the underlined word “earwax” mean in the passage?小题2:In the first paragraph, the writer wants to ___________. A.tell us many beautiful sounds | B.describe the uses of ears | C.explain the kinds | D.show the importance of ears | 小题3:Which of the following is NOT mentioned by the writer?A.Hearing problems caused by diseases. | B.People with hearing problems. | C.Ways to protect our ears. | D.Danger of loud noise. | 小题4:Hearing problems may be caused by _________. A.a little earwax | B.learning problems at school | C.noise louder than 85 decibels | D.earplugs that can only cut noise by 15 decibels | 小题5:The underlined sentence means ________. .A.when you get older, you know it’s not polite to ask “What?” | B.when you get older, you still have good hearing | C.when you get older, you won’t ask questions | D.the older you are, the fewer questions you’ll have |

When does music in public places become noise pollution? You may like at least some kind of music. But the problem is that, in lots of places, you’re made to hear somebody else’s choice in music. Say you’ve just landed at an airport. At the airport, the “background” (背景)music may be played loudly. When you are on the way to your hotel, there may be another kind of music played by the taxi driver. Then you finally reach your hotel. But when you are taking the elevator(电梯),there is elevator music. You go out to dinner and end up in a place where the owner of the restaurant thinks music will help make you eat more and spend more. Then a person playing the violin comes around. This is called the “music wallpaper”. It is to make you buy more and eat a lot. Even the government thinks this is “noise pollution,” especially when the music is too loud. Noise pollution may be bad for our hearing. It’s also bad for some of our daily activities, such as sleeping, conversations and so on. The fact that you can’t see, taste or smell it may help explain why it has not received as much attention as other kinds of pollution, such as air pollution or water pollution. The air around us is always filled with sounds, but most of us would not think we are surrounded(包围) by noise. This can be bad for our health. So many people like soft and quiet music in their house. 小题1:In the restaurant, the music is to make you _____________.A.have a nice meal | B.eat more food and spend more money | C.enjoy some wonderful music | D.have a great time in the restaurant | 小题2:This passage doesn’t talk about ___________.A.food pollution | B.water pollution | C.air pollution | D.noise pollution | 小题3:Music in public places becomes noise pollution because __________.A.it’s played at the airport | B.it’s played by the taxi driver | C.it’s played when you are taking the elevator | D.you are made to hear someone else’s choice in music | 小题4:From the passage we know that ___________.A.music that is too loud is bad for our health | B.people pay as much attention to noise pollution as they do to air pollution | C.people like loud music in their house | D.most people think that there’s lots of noise around us |

When you return 37 your studies, your mind will be refreshed(清醒的) and you"ll learn more 38 study better. Psychologists(心理学家)39 that learning takes place in this way. Here take English learning 40 an example. In the first few months you can make progress and you feel happy. Then your language study seems 41 on the same level.

Learn slowly and you"re sure to get a good result.
