It is...that…句式英語(yǔ)語(yǔ)法強(qiáng)調(diào)句知識(shí)點(diǎn) 1
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)樘預(yù)，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×恕?/p>

注意1：該結(jié)構(gòu)可以對(duì)所有成分（謂語(yǔ)除外）進(jìn)行強(qiáng)調(diào).
I saw him yesterday.
對(duì)主語(yǔ)進(jìn)行強(qiáng)調(diào)：It wasIwho/thatsaw him yesterday.
對(duì)賓語(yǔ)進(jìn)行強(qiáng)調(diào)：It washimwho/thatI saw yesterday.
對(duì)狀語(yǔ)進(jìn)行強(qiáng)調(diào)：It wasyesterdaythatI saw him.
對(duì)謂語(yǔ)部分強(qiáng)調(diào):Ididsee him yesterday..
注意2：is/was只能是單數(shù)，不能寫(xiě)成are
Itwasthe beautiful birds that stunned me.
注意3：當(dāng)所強(qiáng)調(diào)的是人時(shí)，that可以替換為who
It is my sisterwhoalways helps me out.
注意4：在informal場(chǎng)合，that/who可以省略
A: You've met my mother, haven't you?
B: No, it was your sister(that)I met!
注意5：強(qiáng)調(diào)句去掉it is…that/who…之后剩下的是一個(gè)完整的句子
It wasthe governmentthatguarantee the running of the country.
注意6：Not until句型的.強(qiáng)調(diào)
It wasnot until his wife leftthathe came back.
注意7：it is可以加上情態(tài)動(dòng)詞
It might bein this roomthathe met her.
It might have beenJohnthatbought a present for Mary yesterday.
