讲一下一个强调句和一个倒装句

Question

原句：He didn't go to bed until his father came back.
强调句：It was not until his father came back that he went to bed.
倒装句：Not until his father came back did he go to bed.
请根据原句给讲讲这句话是怎么倒装和强调的，我刚开始学这样的高中语法，老师讲了一下，没听明白。说什么not until要放在一起……

Answer 1

先说一下这个倒装句：Not until his father came back did he go to bed.
当句首是否定词时，需部分倒装。这里你用倒装句型的话需把not放在句首，从句until his father came back紧接着照写；主句需倒装，即did he go to bed。
再说一下这个强调句。it型的强调句型为：it is/was+要强调的部分+that/who，这里强调的是until引导的时间状语，而在until引导的时间状语从句中，若主句是否定式，则不论是倒装还是强调，都需将not 前置，即与until连用。
我这几天也在给学生讲强调和倒装，希望对你有帮助，有不知道的还可以问我！

Answer 2

not until 在一起是时间状语，倒装句一般把状语提前，地点状语，条件状语什么的都可以。

强调句是 It be(有时态变化）。。。that

把你要强调的东西放到省略号处即可起强调作用，除了谓语（就是动词）什么都可以强调。

Answer 3

it was that 是强调的结构
当 not until 放在强调句中时，从句不用倒装。即为陈述，主谓的顺序，his father come back.
而只有not until 时，not是否定词，放在句首要倒装。

Answer 4

强调句结构
It is/was+被强调部分+that...
强调句去掉It is/was 和that 句子仍然完整

倒装句就是 否定词引导 助动词提前
