Answer 1

1、since2、before3、that/when4、since5、when6、that7、that第六第七句是强调句型，第七句是"it be not until…that…句式的强调结构。第三句可以看作强调句型，也可以看作when引导的时间状语从句。关于强调句型：一、受基本结构的影响将非强调句型误判为强调句型 大家知道，英语强调句型的基本结构是it is…that…，而不是it is … when…，所以有的同学下题选择了A：It was ten o’clock ______ he came back.
A. that B. when C. so D. which其实此题最佳答案为B，这不是一个强调句型。when引导的是一个时间状语从句，全句意为“当他回来时，时间是10点钟”。比较以下强调句型：It was at ten o’clock that he came back. 他是10点钟回来的。
It was after ten o’clock that he came back. 他是在10点过后回来的。
It was before ten o’clock that he came back. 他是在10点前回来的。再比较：It is autumn when leaves fall. 当树叶落的时候就是秋天了。
It is in autumn that leaves fall. 树在秋天落叶。另外，下面的句子也不是强调句型：1. It’s a long time ______ I met you last.
A. that B. since C. when D. which2. “Was it here _____ you were away talking to a friend?” “Sure. But when I got back there, it was gone.”
A. that B. while C. which D. where以上两题均选B，第一题填since，其意为“自从”；第2题填while，其意为“在……期间”。
