高二英语Module 6 Unit 4 Helping people around the world Grammar译林出版社 【本讲教育信息】 一. 教学内容： Unit 4 Helping people around the world 二. 教学目标： Reading Strategy、Words and expressions 三. 教学重难点： Words and expressions （一）Unreal conditionals: other cases 1. 表假设： 现在：If+ did/were, would/could/should/might do 过去：If+ had done, would/could/should/might have done 将来：If + did/were/were to do/should do, would/could/should/might do 2. 表建议，要求，命令的语气 suggest/advise/order/command/require/request/demand/insist及其名词后引导的表语从句和同位语从句中， 从句用(should) do 3. It’s necessary/important/… that (should) do 4. wish后所接从句 现在 did 过去 had done 将来 would/could do 5. would rather 现在 did/were 过去 had done 6. if only 现在 did/were 过去 had done 7. as if/though 现在 did/were 过去 had done 8. It’s (high/right) time + should do/did 9. without, but for, otherwise/or后的从句也要使用虚拟语气 【典型例题】 1. The boy acted ____ he had never lived in Canada before. A. as though B. even if C. as D. since 【答案】A as though与as if表示好像，后接从句时应用虚拟语气，对过去的虚拟用过去完成时。这句话表示的意思是：他表现的就像从未在加拿大住过似的。 2. ____ to the doctor right away, he might have been alive. A. If he went B.

A. will allow B. should allow C. would have allowed D. had allowed 【答案】C 这里是虚拟语气表假设的句型，前一句用过去时were， 可知是对现在或将来的虚拟，但由于句中有yesterday的时间状语，表示的是对过去的虚拟，所以用would have done，意思是“如果你再大一点的话，我昨天就会允许你去了。” 4. The secretary suggested that they ____ the men in at once. A. had brought B. should have brought C. brought D. bring 【答案】D suggest表建议，后接从句用虚拟语气that sb should do, that、should 可省略， 故选D。 5. I wish I ____ able to tell him all about it last night. A. was B. were C. had been D. should be 【答案】C wish表祝愿，后接从句用虚拟语气，对过去的虚拟用过去完成时，对现在的虚拟用过去时，对将来的虚拟用would/could + do，这里有时间状语last night，故用过去完成时表对过去的虚拟，正确选项为C。 6. If we ____ here ten m
