第四节 虚拟语气
1. It was essential that the application forms ______ back before the deadline.
A must be sent B would be sent C be sent D were sent
* 答案为C。在表示必须、重要、希望等的形容词advisable, compulsory, crucial, desirable, essential, imperative, important, (im)proper, necessary, preferable, urgent, vital…之后的主语从句中，用should+动词原形，should常省。另外注意，上述形容词在believe, consider, find, think等动词后作宾补时，其后的宾语从句也应用虚拟语气的这种形式。
2. We are all for your proposal that the discussion _________.
A be called off B was called off C should call off D is to call off
* 答案为A。在表示命令、决定、劝告、建议、要求、希望等名词，如advice, command, decision, desire, order, plan, proposal, recommendation, regulation, request, requirement, resolution, suggestion等后的表语从句、主语从句和同位语从句中，应用 (should+) 动词原形。
3. ________before we depart the day after tomorrow, we should have a wonderful dinner party.
A Had they arrive B Were they arriving C Would they arrive D Were they to arrive
* 答案为D。在if引导的非真实条件句中，有时if可省，句子倒装。本句从the day after tomorrow可以判断是对将来的假设，应用should do或were to do的形式，故只能选D.
4. That tree looked as if it ____________ for a long time.
A hasn’t watered B didn’t water C hadn’t been watered D wasn’t watered
* 答案为C。as if/though意为好像、似乎，后面常接虚拟语气，用过去式或过去进行式表示与主句表示的时间同时或之后的事实相反的情况；用过去完成式表示与主句表示的时间之前的事实相反的情况。本句是说树好像很长时间没有浇过水了，这应该是与主句之前的事实相反的情况，故应用过去完成式。
5. Look at the terrible situation I am in! If only I ___________ your advice.
A follow B had followed C would follow D have followed
* 答案为D。if only引导的从句可以单独使用，句中还是用虚拟语气形式，表示与事实相反的愿望。本句是表示与过去事实相反，故应用过去完成式。
6. We didn’t know his telephone number; otherwise we ____________ him.
A would have telephoned B must have telephoned C would telephone D had telephoned
* 答案为A。本句的关键词是otherwise, 表示否则，是对前面给出过去事实的一种假定，故后面主句应用would have done的结构。
7. I’d rather you ________ make any comment on the issue for the time being.
A don’t B wouldn’t C didn’t D shouldn’t
* 答案为C。would rather 后面从句用过去时表示委婉的建议和不大可能实现的愿望；有时也接过去完成式表示和过去事实相反的愿望。“for the time being”意为暂时，肯定不是表示和过去事实相反，故应用过去式。
8. I’d rather _________ than take a bus.
A walk B walked C to walk D walking
* 答案为A。本句是 would rather do than do的结构，表示宁愿…而不愿…，一定要和上面16题would rather接虚拟语气的结构区分开。
9. ______ for my illness
