Question

—What do you think this coat is made _____?

—Wool. It’s used for _____.

A.of, keeping warm B.from, keeping warm

C.in, keeping warmly D.of, keeping warmly

Answer 1

A

【解析】

试题分析：be made of意为“由……制成的”能看出原材料；be made from也意为“由……制成的”，看不出原材料。故第一个空用of; be used for doing意为“用来做某事”; keep+形容词意为“保持……状态”。句意：---你认为这件大衣是有什么制成的吗？---羊毛，它是用来保暖的。结合句意，故选A

考点：考查固定短语的用法。
