四级词汇讲解:
短语protect sb. from…意为“保护某人免受……”;wipe out此处意为“彻底消灭，去除”，是本句的听力难点。not only…but…意为“不仅……而且……”,but之后还可加上also。

英语四级考点归纳：
wipe out除了意为“彻底消灭，去除”外，还有以下含义:

※ “跌倒，翻跌下来”。如:
He wiped out wile skiing and broke his ankle.他滑雪时跌倒了，摔断了踝骨。

※ wipe sb. out意为“使某人疲惫不堪”，被动语态be wiped out表示“疲惫不堪的”。如:
The heat really wipes me up.炎热真是让我筋疲力尽。
After a day's hard work, he was wiped out.辛苦工作了一天，他疲惫不堪。
