2、terday that he bought a book here.要强调谓语动词就要用 do, does, did。如：He did buy a book here yesterday.2、在否定句中It is not without any effort that we can expect to succeed.It is not everything that money can buy.如果原句中含有 notuntil, 为了强调时间状语，须把 not 和 until 放在一起，置于强调结构中的 be 后。例如：原句：The ship could not travel on the
3、sea until the compass came into use.强调：It was not until the compass came into use that the ship could travel on the sea.3、在疑问句中如果原句诗一般疑问句，则用“ Be itthat?” 形式；如果原句是特殊疑问句，则用“疑问词+ be it that?”形式。如：原句：Did the last emperor die in this palace?强调：Was it in this palace that the last emperor died?原句：When did
4、you first meet with him?强调：When was it that you first met with him?二、考点分析1、考查引导词 it。在该句型种 it 是固定用法，一般不可用其它词来更换。如：_is for Mary that John might have bought a new book yesterday.A. This B. That C. It D. ItsHow is _ that you wish to leave!A. it B. that C. this D. Tom2、考查引导词 it 和 be 的一定搭配形式，如：“情态动词+完成式”
