關閉窗口 強調原因狀語
由because引導的原因狀語從句或because of短語可以作為被強調的成分。例如：
It is because the book is so useful for my work that I have bought it.
It was because he was in great difficulty that I tried my best to help him.
I was because of the job that he had taken the flat.
但是，若從句由as或since引導，強調時則改為because，這是因為，because引導的原因從句表示的意義非常強烈，符合強調句的目的。例如：
As she got up late, she missed the first bus. 變為強調句：
It was because she got up late that she missed the bus.
強調方式狀語
It was just as he ordered that I acted.
It was by herself that she completed all the work.
It was with a stick that I managed to beat the dog off.
強調目的狀語
It was for fun that he played the part of a clown.
It is in order to serve the people better in the future that we should study hard now.
強調表語
在系動詞be后的表語不能作為被強調的成分。例如：
不可以說：It is a teacher that he is.
但可以說：It is a teacher that he has become.
強調賓語補足語
It was chairman that they elected him.
It was white that they painted the door.
（三）強調句的疑問句式、感嘆句式和否定句式
強調句除了有陳述句式外，還有一般疑問句式、特殊疑問句式、感嘆句式和否定句式幾種類型。
強調句的一般疑問句式
直接把is或was提到it之前，強調句的一般疑問句是Is (Was) it+被強調部分+that+句子的其他成分。例如：
Was it Tom that found your pen in the classroom yesterday?
Was it in 1939 that the Second World War broke out?
Is it from advertising that a newspaper earns a lot of its profits?
Was it not until 12 o’clock that he went to bed?
It was Mike that sent the old man to the hospital, wasn’t it?
強調句的特殊疑問句式
疑問詞+ is (was) it + that +句子的其他成分，特殊疑問詞即是被強調的成分。例如：
Who was it that found your pen in the classroom yesterday?
When was it that the Second World War broke out?
Where was it that you lost your cell phone?
How was it that he managed to get my address?
How long ago was it that you last saw her?
What was it that had made you so sad?
Why was it that silver was not widely used as conductor?
