15、thers answers in a hurry（现在）.If you had asked your mother how to cook last week（过去）, you would know clearly each cooking step of the dish（现在）.虚拟语气的倒装如果从句中有were，should，had，则需要倒装。倒装方法：将if省略，再把were，should，had挪到从句的句首。 注：如果从句中没有were，should，had，则不能省略if，也不可倒装。例句：原句：If my bigger brother were here, he would
16、help us to move the heavy box.倒装：Were my bigger brother here, he would help us to move the heavy box.原句：If the child had been more careful, he would not have made such a foolish mistake.倒装：Had the child been more careful, he would not have made such a foolish mistake.原句：If you should make great prog

31、少必要的说明解释。而非限制性定语从句是先行词的额外说明，是可以省略的，省了也不会影响句子的意思和整体性，并且与主句之间常用“，”隔开。比较例句：This is the book (which/that) I bought yesterday. （限制性）This book, I bought yesterday, is very inspiring. （非限制性）通常是非限制性定语从句的情况分析：Steven Spielberg, (whom) I admire very much in Hollywood movie-making field, won another Oscar Award

36、从句、宾语从句、表语从句和同位语从句等。引导名词性从句的连接词重点概括如下：1. 连接词：that, whether, if （只起连接主句和从句的作用，在从句中不作任何成分）注： that-从句作主语时，常用it作先行词放在句首作为形式主语，而将that-从句放在句末，避免头重脚轻。 1. It is necessary (a.) that 2. It is known -ed分词 that 3. It is a pity (n.) that 4. It seems (vi.) that 2. 连接代词：what (whatever), who (whoever), whom, whose,

40、 child is fearful of whether another war will break out at any moment.六、倒装简明概述：倒装句由全部倒装和部分倒装组成。全部倒装是把句中的谓语部分全部挪到主语前面，时态通常是一般现在时和一般过去时；部分倒装则是将谓语的一部分，如助动词或情态动词倒装于主语之前。如果谓语没有助动词或情态动词，则需要我们帮助补充助动词，如do，does，did，并将它们放在主语的前面。全部倒装（时态通常是一般现在时和一般过去时）：A. 句中如有副词here, there, now, then, away, hence, thus, etc.位于句
41、首，谓语动词为come, go, be, stand, fall, lie, etc. 典型例句：Away ran the child.There lives a tiger.Here is your money.B. 表示方位/运动方向的副词（如in, out, away, off, up, down, etc.）位于句首，谓语表示运动的动词（如come, go, jump, run, swim, stand, rush, etc.）。例句：Away swam a whale.C. 地点状语位于句首例句：Under the tree rested an old lady.D.
