(单选题)

The snow made them cold, so they had to make a fire warm.

A.feel; keep

B.to feel; to keep

C.feel; to keep

D.to feel; keep

参考答案：C

参考解析：

考查非谓语动词。句意：下雪让他们感到寒冷，所以他们决定生火来取暖。make sb. do sth.意为“使某人做某事”，在这里make是使役动词，主动语态，后面应接动词原形作宾补；根据句意可知，第二个空用不定式来表目的。故选C。

知识点：

The snow made them ______cold, so they had to make a fire ______warm.
