注：强调句中的时态要根据原句的时态而定。即原句为过去某种时态，则强调句中的be就用过去时;原句为现在的某种时态，强调句中就用be的现在时态。有时还可以用It mightbe/must have been/can’t be…that等句式。

强调句的判断：强调句型可以通过“还原法”来进行判断，若删除强调句型结构后，句子能还原为一个完整的句子，就是强调句。强调句可以看作是用固定的表达-It is/was…that(which, who, whom, where, when)…, 将句子的某个成分(除了谓语)进行重点强调。但是，去掉这个固定的句型部分，句子本身并无任何变化。
倒装共分两类：全部倒装和部分倒装。全部倒装是指将全部谓语动词都放在主语之前。部分倒装是指将谓语的一部分如助动词，系动词或情态动词放在主语之前。如果句中的谓语没有助动词或情态动词，则需添加助动词do, does或did, 并将其放在主语之前。
