1、按考点分类练习i.虚拟语气在条件句中的用法主/从句 时间条件从句主句过去had+过去分词would(should/could/might) have现在过去式（be用 were）1过刀词would (should/could/migh t) +动词原形将来过去式/should/ were to+动词原形would (should/could/migh t) +动词原形1.虚拟语气用于if条件句中，主从句的谓语动词的相应形式参见上表。2. 虚拟语气用于错综时间条件句中，主从句动作发生的时间不一致，这时主从句动词的形式应根据 句意或时间来调整，选用适当的虚拟形式。3. 如果条件句中包含有一个助动词
2、、情态动词、动词be或have，有时可以把if省略掉，但这时要 把助动词、情态动词、动词be或have放在主语前。4. 表示“若不是之意时，可以用如下两种句型：If it werent for. =but for意为“若不是（对现在情况的假设）”。If it hadnt been for. =but for意为“当时若不是（对过去情况的假设）”。5. 在含蓄条件句中，可以用有些介词（with, without, but for），连词（or, otherwise, but,however）、不定式短语、名词短语或陈述句表示虚拟的条件。专项练习1.Mr.A.Browna house if he
