【答案详解】
1. B。It’s time you did 为 It’s time you thanked Aunt Lucy for her present 之略。按照英语语法，it’s time 后从句通常要用过去式。
2. A。虽然前有虚拟条件句, 后有使用了虚拟语气的宾语，但 I don’t know 却宜用一般现在时，因为 I don’t know 表述的是现在的真实情况，句意为“我要不是有幸遇到你，我真不知(指现在不知)我会做出什么蠢事来”。
3. D。这是otherwise 引出的含蓄虚拟语气，再根据前面的 hesitated 可进一步知道这是与过去事实相反的虚拟语气，由此可推知答案选 D。
4. C。if only 意为“要是……就好了”，其后的句子谓语要用虚拟语气，同时根据 as the doctor instructed 中的过去时态可知从句是与过去事实相反，故选 C。
5. A。without 引出的介词短语为一个与现在事实相反的含蓄条件句。
6. A。在表示“建议”的advice, suggest等后的宾语从句的谓语用“(should +)动词原形”。insist表示“坚持认为”讲，它的宾语从句的谓语不用虚拟语气。
7. C。Had it not been for…=If it had not been for…(要不是因为)表示与过去事实相反的假设。
8. B。当动词suggest当“建议”时，后面的宾语从句用(should)+动词原形；当“暗示、表明”时用陈述语气。
9. D。without… 是表示与现在事实相反的含蓄条件句，主句用 would be。
10. A wish 后的宾语从句的谓语要用过去式表示虚拟语气。Spent 是过去式，所以 wish 从句是表示与过去事实相反的情况，从句谓语用“had +过去分词”。
