1.It+be+...+that...强调句型
【典型例句】

要紧的是你做的而不是说的。

【知识小结】
(1)要强调句子的某一部分(通常是主语、状语、宾语),可以把it当作先行词。这种句子
结构是"It is(was)+被强调部分+that(who,whom)+句子的其余部分"如果被强调的部分是
人,可以用who,whom代替that,如:It was Tom who broke the glass.
是汤姆打破了玻璃杯。
It was the glass that Tom broke.
汤姆打破的是玻璃杯。
(2)强调结构只是加强句子的语气,不改变句子的语序,也不改变句子的结构。强调结构还可用于一般疑问句或特殊疑问句或其他句式中,在特殊疑问句中,疑问词要提到句首。如:
Where was it that the accident happened?
那个事故是在哪儿发生的?
How was it that you came here?
你是怎么来这儿的?
What was it that you wanted?
你想要什么?
(3)在强调句型中,be动词要用单数形式。
2.It was/will be+一段时间+before要过多久才......
【典型例句】
It may be many years before we meet again.
大概要过许多年我们才能见面。
It will be a long time before we finish the dictionary.
要过一段时间我们才能完成这本字典。
