答案解析
1. 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。
2. 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。
3. 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。
4. 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。
5. 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。
6. 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。
7. 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.
8. 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”。
9. 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
10. 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!”
