谁给我讲下SAT中的虚拟语气.

答案

虚拟语气的基本结构是：对现在的虚拟: if…were/did…, …should/ could/ would do…
对过去虚拟: if…had done, …should/ could/ would have done…
对将来虚拟: if… were to do…, …should/ could/ would do…
if…should do…, …should/ could/ would do…
if…did…, …should/ could/ would do…
在对过去的虚拟和对将来的前两种虚拟中,had/were/should可放在句首倒装.eg.Had i finished my homework on time, i would not have been published by my teacher.
同时如果句子中的一个动作陈述的是事实,就不用虚拟语气了.
SAT语法中关于虚拟语气的题明显增多,考察难度也有点加大,重点要关注对过去和将来的虚拟及倒装形式.以下是SAT历年真题中的虚拟语气难题,楼主可一块看看,找找做题的感觉.08/10 S5-5,08/10 S5-16,10/1 S6-11,10/10 S5-18,11/1 S7-8,11/5 S5-17+S10-13
