答案(1)

1. C. 因为在表示“要求”的require, request, ask, demand等动词后的宾语从句的谓语要用“(should+)动词原形”，句中referred to是过去分词短语，作the computer equipment的定语，所以选C(from www.yygrammar.com)。

2. C. 因为在it is surprising后的that从句中，谓语要用“should +动词原形”，其中should含“竟然”之意，不可省略。

3. B. 因为It’s (high /about) time后面的从句的谓语动词通常用过去时态。

4. D. 因为requirement后的表语从句的谓语要用“(should +)动词原形”；material(材料)与heat(加热)是被动关系，用被动语态，所以是be heated。

5. D. 因为wish后的宾语从句中的谓语动词要用过去式，此题的study business是与过去事实相反的情况，所以用had studied business(from www.yygrammar.com)。

6. C. 因为主语是demand时，其后的表语从句的谓语要用“(should +)动词原形”。

7. C. 因为句中otherwise (否则)表示与过去事实相反的情况，所以用would have done。

8. D. 因为介词短语without…表示与现在事实相反的情况，所以用would be。

9. B. 由had not gone可知，条件句是与过去事实相反的情况，而now提示我们，主句是与现在事实相反的情况，所以用would be。

10. D. 因为if only (要是…就要了) 其后的句子要用过去式表示虚拟语气，由as you do可知，是与现在事实相反，所以选knew。

答案(2)

11. A. 因为but for (要不是因为、如果没有) 通常要与虚拟语气连用，由fifteen years ago可知，这是与过去事实相反的情况，所以选would have died(from www.yygrammar.com)。

12. A. 因为would come earlier是与过去事实相反的虚拟语气，而后面分句表示的是事实：当时我的确不知道…所以用一般过去时，选A。

13. C. 因为that从句是suggestion的同位语，应当用“(should+) 动词原形”表示虚拟语气，又因the students与give是被动关系，所以选be given。

14. A. 因为Wang Ling是中国人的名字，显然不是英国人，所以as if从句的谓语要用与现在事实相反的情况，所以用were。

15. A. 因为had it not been for the policeman = if it had not been for the policeman (如果没有警察) ，显然是与过去事实相反的情况，主句中的谓语应是would have lost。

16. B. 因为由主句谓语可判断，表示的是与过去事实相反的情况，所以虚拟条件句中的谓语应用过去完成时，Had the captain been = If the captain had been。

17. A. 由于从句谓语为一般过去时，表示的是对现在的虚拟，故主句谓语用过去将来时，表示。Were it not for the snowy weather=If it were not for the snowy weather.

18. B。这是个错综时间虚拟条件句：主句与现在事实相反，条件句与过去事实相反。句意为“如果我不是在七岁时就迷上了Melinda Cox 图书馆，我真不能想象我如今会在做什么”。

19. D。本题考查目标与1996上海同。由otherwise和hesitated可知，这是与过去事实相反的虚拟语气，谓语动词用 would+ have+ 过去分词构成(from www.yygrammar.com)。

20. B。wish 后面宾语从句的谓语总是用过去时态。此题是表示与现在事实相反的愿望，从句谓语用一般过去时。句意为“我多么希望每个家庭都有座有一个漂亮花园的大房子啊！”
