与定语从句的比较 ◎强调句中的It没有实际意义，It be与that可同时被省略；而定语从句中的It是主语，It be与that不可同时省略；

◎强调句型中be的时态须跟后面句子的时态相一致；而定语从句中主句谓语动词be的时态须由主句的时间确定

◎强调句将句子中的that不能省略，并且即使前面的名词是事物时，也不能将that换成which；而定语从句中的that作宾语时可被省略，并且当先行词是事物时可用which代替。 ◎当it be后面的时间、地点名词作主语、宾语或表语时，引导词可用that / which；而作其他成分时，引导词须用when / which如：

It is a day when the people celebrate their victory. 这是人们庆祝他们的胜利的日子。 (when所引导的从句对a day进行说明，是定语从句)

It was on that day that people celebrated their victory. 就在那一天，人们庆祝了他们的胜利。(强调on October 1, 1949)

与状语从句的比较 ◎状语从句句首的It本身就是句子的主语；而强调句首的It不作任何成分也没有实际意义。

◎状语从句的连接副词that及句子前面的It be不能去掉

◎状语从句的引导词可以是when / where，而强调句型中的that不能用其他词代替。如：

(1) It is such an interesting book that we all like it very much. 它是一本如此有趣的书，我们大家都非常喜欢。(结果状语主从复合句)

It is such an interesting book that we all like very much. 我们大家都非常喜欢的就是一本如此有趣的书。(强调such an interesting book)

(比较：It is such an interesting book as we all like very much. 这就是我们大家都非常喜欢的如此有趣的书。定语从句)

(2) It was already morning when he woke up. 当他醒来时，已经是早晨了。(时间主从复合句)

It was the next morning that he woke up. 就在第二天早晨他醒来了。(强调the next morning)
