问题 If you intend to melt the snow for drinking water, you can________extra purity by running it through a coffee filter.
选项 A、assure
B、insure
C、reassure
D、ensure
答案D
解析 如果你打算把雪融化成饮用水，你可以用咖啡过滤器过滤一下来确保获得更高的纯度。动词辨析题。assure意为“保证”，用来表示向某人保证某事将要发生，既可以用来确信某事，也可以表示使某人确信，assure的宾语通常是人，一般不直接跟sth. 或that从句，其常用结构是assure sb. of sth.／assure sb.+that从句；insure意为“为……投保”；reassure意为“使安心，使消除疑虑”，一般用于reassure sb.+that从句或reassure sb. about sth. ensure意为“保证，确保”，用来表示使某行为或某件事的结果得以保证，即确保某事发生，其常用结构是ensure sth.／ensure+that从句／ensure sb. sth.。根据句意可知，D项为答案。
