(2) It was a room where we used to have meetings. 

它是我們過去常在開會的房子。(where 所引導(dǎo)的從句對前面的room進(jìn)行說明，它是定語從句)

It was in the room that we used to have meetings. 

過去我們開會就在這間房子里。(in the room是被強(qiáng)調(diào)的部分，本句是強(qiáng)調(diào)句型) 

(3) It is a day when the people celebrate their victory. 

這是人們慶祝他們的勝利的日子。  (when所引導(dǎo)的從句對a day進(jìn)行說明，是定語從句) 

It was on that day that people celebrated their victory. 

就在那一天，人們慶祝了他們的勝利。(強(qiáng)調(diào)on October 1, 1949) 

3．強(qiáng)調(diào)句與狀語從句的比較

◎狀語從句句首的It本身就是句子的主語；而強(qiáng)調(diào)句首的It不作任何成分也沒有實(shí)際意義。

◎狀語從句的連接副詞that及句子前面的It be不能去掉(from )。

◎狀語從句的引導(dǎo)詞可以是when / where，而強(qiáng)調(diào)句型中的that不能用其他詞代替。如：

(1) It is such an interesting book that we all like it very much. 

它是一本如此有趣的書，我們大家都非常喜歡。(結(jié)果狀語主從復(fù)合句) 

It is such an interesting book that we all like very much. 

我們大家都非常喜歡的就是一本如此有趣的書。(強(qiáng)調(diào)such an interesting book) 

(比較：It is such an interesting book as we all like very much. 這就是我們大家都非常喜歡的如此有趣的書。定語從句)

(2) It was already morning when he woke up. 

當(dāng)他醒來時(shí)，已經(jīng)是早晨了。(時(shí)間主從復(fù)合句)

It was the next morning that he woke up. 

就在第二天早晨他醒來了。(強(qiáng)調(diào)the next morning)
