It is...that…句式通常不能強(qiáng)調(diào)哪些成分

有這樣一道考題：

It was a teacher that she __________.

A. was                        B. seemed                        C. looked                        D. married

此題應(yīng)選D。從句意上看似乎4個(gè)選項(xiàng)都行，其實(shí)這里只能填D。因?yàn)樘?/SPAN>A，B，C 中的任意一個(gè)選項(xiàng)，都會(huì)導(dǎo)致句中的 a teacher成為表語(yǔ)，然而按照強(qiáng)調(diào)句句法規(guī)則，It is...that這一強(qiáng)調(diào)句型是不能強(qiáng)調(diào)表語(yǔ)的。一般說(shuō)來(lái)，以下成分不能用于強(qiáng)調(diào)句中的被強(qiáng)調(diào)部分：

1. 表語(yǔ)：

她很美。

正：She is beautiful.

誤：It is beautiful she is.

他是醫(yī)生。

正：He is a doctor.

誤：It is a doctor that he is.

但是賓語(yǔ)補(bǔ)足語(yǔ)卻可以用作被強(qiáng)調(diào)部分：

他們選他擔(dān)任主席。

正：They elected him chairman.

正：It was chairman that they elected him.

2. since 和 as 引導(dǎo)的原因狀語(yǔ)從句(但 because 從句卻可以)：

他不能來(lái)是因?yàn)樗�病了�?/SPAN>

正：It is because he is ill that he can’t come.

誤：It is since[as] he’s ill that he can’t come.

3. although 引導(dǎo)的讓步狀語(yǔ)從句：

雖然累了，但他還是去了。

正：He went although he was tired.(www.hz123456.com)

誤：It was although he was tired that he went.
