四、考查not...until句式的強(qiáng)調(diào)結(jié)構(gòu)

其基本形式為It is (was) not until…that…。比較：

He didn't come until his wife left. 他妻子走了之后他才來。

→It was not until his wife left that he came. 他妻子走了之后他才來。

They didn't start until the rain stopped. 直到雨停他們才出發(fā)。

→It was not until the rain stopped that they started. 直到雨停他們才出發(fā)。

注：這類句型不用倒裝語序，但若改成Not until…，則要用倒裝。如：

Not until his wife left did he come. 他妻子走了之后他才來。

Not until the rain stopped did they start. 直到雨停他們才出發(fā)。

【真題實(shí)例】（答案分別為DBD）

1. It _________ we had stayed together for a couple of weeks _________ I found we had a lot in common.

A. was until; when     B. was until; that       C. wasn’t until; when   D. wasn’t until; that

2. It was not until she got home _________ Jennifer realized she had lost her keys.

A. when                   B. that                      C. where                      D. before

3. It wasn’t until nearly a month later _________ I received the manager’s reply.

A. since                    B. when                   C. as                            D. that

五、考查強(qiáng)調(diào)句與非強(qiáng)調(diào)句的辨別

1. 設(shè)置陷阱，使考生將強(qiáng)調(diào)句誤判為非強(qiáng)調(diào)句。如：

It might have been John _________ bought a present for Mary yesterday.

A. that                       B. when                  C. what                      D. which

【解析】答案選A，為強(qiáng)調(diào)句型，由于句中動(dòng)詞be采用了might have been這一復(fù)雜結(jié)構(gòu)，所以許多同學(xué)們可能會(huì)看不出它是一個(gè)強(qiáng)調(diào)句型。

2. 設(shè)置陷阱，使考生將非強(qiáng)調(diào)句誤判為強(qiáng)調(diào)句。如：

It was evening       we reached the little town of Winchester.

A. that                       B. until                    C. since                     D. before

【解析】答案選D。有的考生一看到句首的it was，再聯(lián)系到選項(xiàng)中的that，就以為這是考查強(qiáng)調(diào)句。其實(shí)錯(cuò)了。此題是考查連詞before的用法。因?yàn)槿サ?/FONT>It was…that這一結(jié)構(gòu)后，原句不能成為一個(gè)完整的句子，所以這不是強(qiáng)調(diào)結(jié)構(gòu)。句意是：我們還沒有到達(dá)Winchester這個(gè)小鎮(zhèn)，天就夜了。
