【考点】考查not…until…的强调句形式。

【解析】固定句式not…until…的强调句形式是it was not until…that…（注意that从句要用肯定式）。又如：

It was not until she got home that Jennifer realized she had lost her keys. 直到她回到家，珍妮弗才发现钥匙丢了。

You won’t succeed until you try three times.

It is not until you try three times that you will succeed.

【答案】C

It was not until midnight that he went back home after the experiment. 实验结束后，他直到午夜才回家。

强调句的结构是It is 被强调部分 that/who …。比如陈述句：Tom lent me money when I was in trouble.我需要强调主语，句子就会写成这样：It was Tom who lent me money when I was in trouble.把我们要强调的部分Tom提前到that/who前面，然后其余的部分按照原顺序放在后面就好了。

可是，not…until…结构是不同的。它们是一体的，如果想要强调until后面的部分，不仅仅需要把until部分提前，还要把not一起提前才可。整个句子相应的也会有一点改变。例如：

I didn’t realized that she was one of my classmates until she took off her sunglasses. 直到她脱下太阳镜我才认识到她是我的一个同学。

如果我们想要强调直到她脱下太阳镜，该怎么改呢？我们需要把not和until she took off her sunglasses一起提前到that前面。It was not until she took off her sunglasses that I realized that she was one of my classmates.

试将下列句子改为it is…that…强调句，强调until部分。

1: Tom didnt go to sleep until the programme was over.

2: Tom didn’t understand it until his teacher had explained it three times.

3: I won’t leave until you give me my money.

4: They didn’t begain the lunch until I came back.

参考答案：

1: It was not until the programme was over that Tom wen to sleep.

2: It was not until his teacher had explained it three times that Tom understood it.

3: It is not until you give me my money that I will leave.

4: It was not until I came back that they begain the lunch.
