留美老师带你每日说英文 第470期:耳垢对耳朵的好处(在线收听

 台湾籍旅美老师今天交给我们的句子是:

Now, your cerumen is protecting you from infection, lubricating your ears, and it's keeping a health record for your doctor. But even knowing all of that, there are those of you who will totally wanna get rid of it.
现在,你的耳垢再保护你免受感染、润滑你的耳朵及为医生记录你的健康史。但即使知道这么多好处之后,还是有人千方百计地想要除掉耳屎。
