Not until he finished his homework him to...

Not until he finished his homework him to watch TV in the evening . A．his mother allowed B．his mother had allowed C．did his mother allow D．had his mother allowed

Answer 1

C

考查倒装句与时态。句意：晚上，直到他完成了作业，他的母亲才允许他看电视。根据条件从句时态，可知主句描述的是过去发生的动作，故用过去时态。当not until位于句首时，主语用部分倒装，助动词提前，故选C。
