Question

11．twelve，don't，bed，yesterday，I，go，until，to o'clock （．）I didn't go to bed until twelve o'clock．．

Answer 1

分析 昨天我直到十二点才睡觉．

解答 答案：I didn't go to bed until twelve o'clock．根据句子中连词until可知这里要用not…until句型，yesterday昨天，用于一般过去时，助动词don't要改成didn't，go to bed上床睡觉，故填：I didn't go to bed until twelve o'clock．

点评 解答这道题，关键要考虑句子中的连词until，考查not…until引导的时间状语从句．
