Some people’s ears produce wax like busy little bees. This can be a problem even though earwax(耳垢)appears to serve an important purpose.
Experts say it protects and cleans the ear. It【B1】______dirt and other matter and keeps insects out. Doctors think it might also help【B2】______infectious diseases. And the waxy oil keeps ears from getting too dry. So earwax is good. And there are two kinds. Most people of European or African【B3】______have the "wet" kind: thick and sticky. East Asians commonly have "dry" earwax.
But you can have too much of a good thing. Some people may have too much wax in their ear canal. Earwax is【B4】______expelled; it falls out of the ear or gets washed away. But【B5】______wax can harden and form a blockage that【B6】______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【B7】______is sometimes necessary. But you have to use a safe method or you could do a lot of damage.
Experts at N.I.H., the National Institutes of Health, suggest some ways to treat【B8】______earwax yourself. They say the wax can be softened with mineral oil or ear drops. Another way to remove wax is known as irrigation. With the head upright,【B9】______the outer part of the ear. Gently pull upward to straighten the ear canal. Use an injection【B10】______to gently direct water against the wall of the ear canal. Then turn the head to the side to let the water out.
【B4】
选项
答案
normally
解析
根据空格前的is和空格后的expelled,可知此处可能要填入副词来修饰expel“排出”。nor-really指“通常地”。
