---You'd better not go out now. It's raining.---It doesn't matter. My new coat can keep ________ rain.A.inB.ofC.withD.off

D解析该题考查keep构成的短语的用法，第一个会话者不让对方出去，因为天正在下雨．从对方说的it doesn't matter.可判断出，此人的新外衣隔雨．keep off表示“避开”、“挡住”，是及物的动词短语．
例如：
Put on your straw hat to keep off the sun.
戴上你的草帽以避日晒．
We had to think of a way to keep off the rain.
我们得想个办法挡雨．
