Answer 1

1. C
demand的宾语从句必须采用虚拟语气，即从句的谓语动词由“should + 动词原形”构成，且shoule可以省略。

2. A
as if引导的从句如果表示虚拟的情况时，也必须采用虚拟语气。
如果从句动作发生在主句动作之前，则从句采用过去完成时。

3. B
the suggestion的同位语从句，不缺成分时，从句用that引导；
且从句必须才用虚拟语气，即从句的谓语动词由“should + 动词原形”构成，should可以省略。

4. B
“It's important that从句”如果表示说话人的某种语气时，须采用虚拟语气，即that从句的谓语动词由“should + 动词原形”构成，should可以省略。

5. C
if引导的条件状语从句如果使用虚拟语气，从句表示对过去的虚拟时，从句用过去完成时；
主句有now，表示对现在的虚拟，则用“would/could/might + 动词原形”。

6. C
同上题。if从句如果是对将来的虚拟，从句可以用“were to do sth”，还可以把were提前至句首，并去掉if.

7. A
同上题。if从句是对将来的虚拟，从句可用“should + 动词原形”，且可以把should提前至从句句首，去掉if；
主句则采用“would/could/might + 动词原形”。

8. B
should have done sth 本应该做某事(但是实际上当时没做)

9. C
could have done sth 本可以/能够做某事(但是当时未能做到)

10. D
wish的宾语从句如果是对过去的虚拟，则从句用过去完成时had done sth。

11. C
if从句的含蓄用法，对过去的虚拟主句用would/could/might have done sth

12. C
“It's high time that从句”，that从句使用虚拟语气，即从句用一般过去时或“should + 动词原形”，此时should不可以省略。

13. A
if only句子使用虚拟语气。多过去的虚拟时，句子使用过去完成时。

14. C
同第11题。
if从句的含蓄用法。对过去的虚拟时，主句使用“would/could/might have done sth”.

15. C
if从句虽然是虚拟，但是if从句里面的那个that引导的同位语从句是事实(the fact)，所以用一般现在时。

Answer 2

1:The teacher demanded that the exam_C___before eleven.
C，demand 有命令的意思，因而用虚拟语气。
demand that sb/sth (slhould)do
A:must finish B:would be finished C:be finished D:must be finished
2:He is talking so much about America as if he __A_there.
B,had been 表示状态。主句+as if (though)+主语+
01.were/过去时 ——〉表示与主句动作同时发生
02.could/would +动词原形——〉表示动作可能在将来发生
03.had+过去分词——〉表示从句谓语的动作发生在主句动作之前

A:had been B:has been C:was D:has gone
3:The suggestion has been made___B_the basketball game____put off.
A:for;to B:that;be C:which ;should be D:to ;being
这里要注意两个地方。suggestion 表示建议的时候要用虚拟语态。因而排除A,D.而B,C后面那部分是正确的。这里用到了同位语从句，“the basketball game____put off”是对suggestion的解释。而同位语从句是用that引导的。因而选B
4:It is important that we _B___wild animals.
It is important that +虚拟语气（很常用也很重要的用法哦）
A:will protect B:should protece C:shall protecet D:are protecting
5:Had you listened to the doctor,you__D__all right now.
虚拟语气从句用了倒装，但后面有right now.因而用would do,与现在的事实上相反.
A:are B:were C:would be D:would have been
6:__C__today,he would get there by Friday.
同样用到了倒装。是与将来事实相反的虚拟语气。
were to +动词原形，should +动词原形
A:Would he leave B:Was he leaving C:Where he to leave D:If he leace
7:Should it rain ,the crops___A_.
从句倒装，与将来事实相反的虚拟语气。should +动词原形， should +动词原形
A:would be saved B:would have been saved C:will be saved D:had been saved
8:You___B_come earlier .The bus left a moment ago.
A:would B:should have C:may D:have。
考情态动词的用法。should have done表示本该做某事确没有完成。
9:I__B_____you some money,but I hadn't any on me then.
A:would lend B:would have lent C:could lend D:may have lent
也是情态动词的用法。would have done本应会做却没有做。我那时会借钱给你的，但是我但是没有带在身上。
10:-Have you ever been to Beijing?
-No,but I wish I___D_.
动作发生在主句之前，因而用had done 的结构。省略done,选D
A:have B:will C:do D:had
11:I'm glad I went over all my notes;otherwise___C_
A:I may have failed B:I'd fail C:I'd have faild D:I'll have failed.
有虚拟语气，went 表示过去某个时段发生的动作，因而与过去事实相反。用have done
12:-What will you do during the summer holiday?
-I don't know ,but it's high time __C__sth....
固定句型，it's high time did should do sth(should 不能省略）
A:I'm deciding B:I'll decide C:I decided D:I decide
13:If only i _A__my watch
反正你就记住,时态倒退一格.与过去事实相反,后面跟过去完成时, had+过去分词
与现在事实相反,后面跟一般过去时
与将来事实相反,后面跟一般过去时或should + 动词原形
A:hadn't lost B:haven't lost C:didn't lost D:don't lose
14:We ___C_the work on time without your help.
A:hadn't had finished B:didn't have finished C:couldn't have finished D:can't have finished也是情态动词的用法。couldnt have done 不可能完成某事
15:If it were not for the fact that you__C__ill,I would ask you to do this right now. 虚拟语气（与将来的事实相反）+同位语从句 后面是now.就表示是现在的情况，因而用一般现在时
A:were B:had been C:are D:should be
（本人已尽力而为啦。。楼主应该好好学习英语的语法知识喔~~~虚拟语气的用法比较复杂。。要慢慢参透喔。介绍这个资料给你吧http://wenku.baidu.com/view/6e540ea1284ac850ad024296.html
祝你好运。O(∩_∩)O ）

Answer 3

D，因为try
to
do
sth是尽力做某事。只有D是有to的，所以选D
第二我不知道啊
