[1]Some people's ears producewax like busy little bees. This can be a problem even though earwax appears to serve an important purpose. Experts say it protects and cleans the ear. It traps dirt and other matter and keeps insects out. Doctors think it might also help protect against infections. And the waxy oil keeps ears from getting too dry.
[2]So earwax is good. It even has a medical name: cerumen. And there are two kinds. Most people of European or African ancestry have the wet kind: thick and sticky. East Asians monly have .But you can have too much of a good thing.
[3]The glands(腺体) in the ear canal that produce the wax make too much in some people. Earwax normally falls out of the ear or gets washed away. But extra wax can harden and form a blockage that interferes with sound waves and reduces hearing. People can also cause a blockage when they try to clean out their ears，but only push the wax deeper inside. Earwax removal is sometimes necessary. But you have to use a safe method or you could do a lot of damage.
[4]Experts at N.I.H., the National Institutes of Health, suggest some ways to treat excessive earwax yourself. One way to removewax is known as irrigation. With the head upright, take hold of the outer part of the ear. Gently pull upward to straighten the ear canal. Use an injector device to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.
[5]The experts at N.I.H. say you may have to repeat this process a few times. Use water that is body temperature. If the water is cooler or warmer, it could make you feel dizzy. Never try irrigation if the eardrum is broken. It could lead to infection and other problems.
[6]After the earwax is gone, gently dry the ear. But if irrigation fails, the best thing to do is to go to a

解析：文章讲述了人都会产生耳垢，不同的种族耳垢的特点也不相同，但都有着好的作用，可以防止耳朵受到感染，防止小的昆虫进入。但是如果产生的耳垢过多，也会影响人的听觉，主体介绍了我们应该怎样把这些过多的耳垢清除出来。专家给了我们一些好的建议。
【小题1】细节理解题。Experts at N.I.H., the National Institutes of Health, suggest some ways to treat excessive earwax yourself.意思是说，专家推荐了一些方法去清除过多的耳垢。所以答案应该是建议好的方法去清除污垢。
【小题2】细节理解题。extra wax can harden and form a blockage that interferes with sound waves and reduces hearing.句意为：过多的耳垢可能会变硬形成堵塞进而会干涉声波降底听力。由此可以判断太多的耳垢会造成坏的影响。所以答案应为：It can hardenand form a blockagethat interferes with sound waves and reduces hearing.
【小题3】细节推理题。Most people of European or African ancestry have the wet kind: thick and sticky. East Asians monly have .But you can have too much of a good thing. 句意为：大多数欧洲和非洲血统的人有比较潮湿的耳垢，而东亚通常有干的耳垢。前后句之前的对比可得出答案应是“dry” earwax / “dry” kind。
【小题4】段落大意题。第五自然段的大意为：专家说，你也许会重复几次这个过程，用和体温一样的水如果水太凉或太热，你可能会头晕。如果耳膜受伤的话，不要去尝试“灌溉”你的耳朵，它可能会感染或者有其它的问题。所以这个过程应为Irrigation./ The irrigation.
【小题5】开放性试题。但文中介绍了其危害，所以应根据If the water is cooler or warmer, it could make you feel dizzy. Never try irrigation if the eardrum is broken. It could lead to infection and other problems. 回答此问题，意思是：如果用冷水或者是热水，你可能会头晕目眩。所以答案应为：Certainly not / No, I won’t.. Because it could make me feel dizzy.
