有這樣一道考題：
It was a teacher that she __________.
A. was B. seemed C. looked D. married
此題應選D。從句意上看似乎4個選項都行，其實這里只能填D。因為填A，B，C 中的任意一個選項，都會導致句中的 a teacher成為表語，然而按照強調句句法規則，It is...that這一強調句型是不能強調表語的。一般說來，以下成分不能用于強調句中的被強調部分：
1. 表語：
她很美。
正：She is beautiful.
誤：It is beautiful she is.
他是醫生。
正：He is a doctor.
誤：It is a doctor that he is.
但是賓語補足語卻可以用作被強調部分：
他們選他擔任主席。
正：They elected him chairman.
正：It was chairman that they elected him.
2. since 和 as 引導的原因狀語從句(但 because 從句卻可以)：
他不能來是因為他病了。
正：It is because he is ill that he cant come.
誤：It is since[as] hes ill that he cant come.
3. although 引導的讓步狀語從句：
雖然累了，但他還是去了。
正：He went although he was tired.
誤：It was although he was tired that he went.
