关于英语倒装句和强调句 。 请帮我看下这两题怎么改。。

Question

1.The students didn't stop talking until the teacher came in.
2.He didn't give up smoking until he got a serious disease.

将这两句改为倒装句和强调句 拜托了 ！　

Answer 1

保证答案准确！

1. 倒装句：Not until the teacher came in did the students stop talking.
强调句：It was not until the teacher came in that the students stopped talking.

2. 倒装句：Not until he got a serious disease did he give up smoking.
强调句：It was not until he got a serioius disease that he gave up smoking.

注：not...until的倒装句/强调句如下（如果until做连词引导时间状语从句，且时态均为一般过去时时）：
倒装句：Not until + 从句 + did + 主句主语 + 主句谓语动词原形...
强调句：It was not until + 从句 + that + 主句（改为肯定句）
