____our mother will allow ____ to see a film after supper?

A．Who do you think, leaving	B．Who do you think, to leave
C．Do you think who, leaving	D．Do you think who, to leave

Answer 1

B

解析试题分析:句意：你认为母亲晚饭后会允许谁去看电影呢？固定短语：allow sb to do sth“允许某人做某事”，排除AC选项，此处是固定结构“疑问词+do you think+句子其他成分”，故选B。
考点：考查固定句式和非谓语动词。
