Some people’s ears produce wax like busy little bees. This can be a problem even though earwax(耳垢)appears to【S1】______an important purpose. Experts say it【S2】______and cleans the ear. It【S3】______dirt and other matter and keeps insects out. Doctors think it might also help protect against【S4】______. And the waxy oil keeps ears from getting too dry. So earwax is good. It even has a medical name: cerumen(耵聍). There are two kinds. Most people of European or African ancestry have the "wet" kind: thick and【S5】______. East Asians commonly have "dry" earwax. But you can have too much of a good thing. The glands(耳道)in the ear canal that produce the wax make too much in some people Earwax is normally【S6】______; it falls out of the ear or gets washed away. But extra wax can harden and form a【S7】______that interferes with sound waves and reduces【S8】______. People can also cause a blockage when they try to【S9】______out their ears, but only push the wax deeper inside. Earwax removal is sometimes necessary but you have to use a【S10】______method or you could do a lot of damage.
A)sticky B)hard C)expelled D)protects
E)listening F)clean G)heating H)safe
I)blockage J)made K)infections L)partly
M)serve N)traps O)slight
【S4】
选项
答案
K
解析
此处空格为动宾结构,应填名词。前文的意思是耳垢具有保护作用,下文用also可知是承接上文的意思。名词中blockage是“堵塞”,根据常识可知耳垢不具有防止堵塞的功能。infection是“感染”之意,自然当选。
