Answer 1

1、 If you had listened to me earlier,you ___ sorry now.
B. wouldn't be错综虚拟 从句与过去相反 主句与现在相反
2、I got close enough to hear them speaking Chinese,and I said"Ni hao" just as I ____ do in China.
B. might 表示可能性
3、___ fired, your health care and other benefits will not be immediately cut off.
B. Should you be从句 与将来情况可能相反 万一。主句是真实句

4、Our holidays were ruined by the weather, so ____ have stayed at home!
A. it was just as well as we B.we might just as well as we
感觉 都不对
答案应该是we might just as well

5、I ____ thank you too much, because without your help my son ____ admitted to his dream university. A.can't; wouldn't have been 前句是真实句追问

___ fired, your health care and other benefits will not be immediately cut off.这句中Should you be fired是主句吗,另外,1.3.4.5句分别都是考察虚拟语气,第2句考察情态动词的使用吗,请再写一次每题的考点分析,谢谢你,讲解得很不错

追答

___ fired, your health care and other benefits will not be immediately cut off.这句中Should you be fired是省略if的从句，省略if后从句要倒装。=if you should be fired万一你被解雇了，
第2句考察情态动词的使用，因为主句是过去时,
