英語語法強調(diào)句知識點：It is...that…句式通常不能強調(diào)哪些成分

　　【導(dǎo)語】英語語法讓很多學(xué)生都頭疼，因為復(fù)雜難懂的句式和詞組有時難以記憶。英語網(wǎng)為大家整理了英語語法大全，希望對同學(xué)們的英語語法學(xué)習(xí)有所幫助。更多內(nèi)容盡在英語網(wǎng)。

　　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個選項都行，其實這里只能填D。因為填A(yù)，B，C 中的任意一個選項，都會導(dǎo)致句中的 a teacher成為表語，然而按照強調(diào)句句法規(guī)則，It is...that這一強調(diào)句型是不能強調(diào)表語的。一般說來，以下成分不能用于強調(diào)句中的被強調(diào)部分：

　　1. 表語：

　　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.

　　但是賓語補足語卻可以用作被強調(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(dǎo)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.
