Question

5．地铁出故障了，他昨晚十点才到家．
There was something wrong with the underground，so hedidn't get home until 10  last night．

Answer 1

分析 didn't get home until．

解答 答案：didn't get home until．这里是说昨晚last night的事情，用一般过去时，表示直到…才，用not…until，到家get home，get是实意动词，借助于助动词did构成否定didn't，后加原形，故答案是didn't get home until．

点评 not…until指的是"直到…才"的意思，如 I did not go home until my mother called me．
我直到我妈妈打电话给我才回家．
当Not until位于句首时，句子要倒装．其结构为：Not until+从句/表时间的词+助动词+（主句）主语+谓语+．如：
Not until the teacher came in did the students stop talking．直到老师进来学生们才停止讲话．
