题目内容
【题目】It is difficult to tell exactly ______ the saying began, but it is probable that it was in the theater or movie industry.
A.where B.when C.why D.that
【答案】A
【解析】tell exactly后面是一个宾语从句,宾语从句中主语、谓语都有,究竟缺的是时间还是地点,but后面就有很清楚的提示——it was in the theater or movie industry。由这个提示得知,难以判断的是谚语的出处(where),因此选A。句意:很难准确判断这个谚语是从哪里开始的,但很有可能是从戏院或电影业开始。
