We can listen to cool music and news reports. And all this is due to（归功于）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. In China，6 children out of 1000 have hearing problems when they are born. They can not hear ordinary sounds clearly. Children who have hearing problems usually also have 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 a problem for all of us. So we should do our best to give our ears special care. Don't forget the following： Try to stay away from places with too much noise. If you have to go，wear earplugs（耳塞）. A pair of earplugs can cut the noise by 30 decibels. When swimming，remember to put earplugs into your cars to stop water from getting in. Never put anything sharp into your ears. If you think you have too much earwax，ask your parents to help you clean it out. Keep these things in mind! Then you won't ask "WHAT？？？" when you are older.（1）In the first paragraph， the writer wants to ____ .
