Question

6．昨晚直到我妈妈回来，我才睡觉．I didn't go to bed until/till my mother came back last night．．

Answer 1

分析 I didn't go to bed until/till my mother came back last night．

解答 答案：I didn't go to bed until/till my mother came back last night．
根据汉语意思，可知此句应用固定短语not…until（till）来表达，意为"直到…才…"，引导一个时间状语从句；此句也可理解为：妈妈不回来我就不会睡觉；根据时间状语"昨晚"last night可知本句的时态应为一般过去时；主句的主语为I，"睡觉"可以用固定短语go to bed表达，由于和not连用为否定句，go为实意动词，所以此处应用助动词did+not即didn't后加动词原形，所以主句可表达为：I didn't go to bed；从句用until或till引导都可，主语为my mother （我妈妈），"回来"用固定短语come back，此处用come的过去式came；后加时间状语last night（昨晚），故从句可表达为：until/till my mother came back last night．故此句可完整地表达为：I didn't go to bed until/till my mother came back last night．

点评 此题考查固定句式的表达．做题时根据汉语意思选用正确的句型是做好此题的关键，还要注意时态的运用．
