Ask him to hurry up with the letters so that I can sign them. 让他带着信赶快来以便我签字。 在以lest 和in case 引导的目的状语从句中谓语动词若属 于过去时，一般要用虚拟语气，由“should+动词原形” 构成；若谓语动词不是过去时，也可以用陈述语气。 Take warm clothes in case the weather is cold. 带上厚衣服以防天气变冷。
六、虚拟语气在其他状语从句中的使用
1. 虚拟语气用在目的状语从句中 在由lest, for fear that, in order that, so that, in case等引 导的目的状语从句中需用虚拟语气，表示“以防，以免”等 意思，其谓语动词多由“should/could/might+动词原形” 构成，should也可以省略。 He was punished lest he should make the same mistake again. 他被处以惩罚以免他再犯同样的错误。 I will not make a noise for fear that I should disturb him. 我不会出声的，以免打扰他。 He put his coat over his son in case he should catch cold. 他把大衣盖在儿子身上以免他着凉。 注意：如果 in order that 和 so that 前的主句是现在时，其 后的从句有时也可用“can/may+动词原形”。
五、虚拟语气在表语从句或同位语从句中的运用
当某些表示建议、请求、命令等主观意向的名词作主语时， 其后的表语从句或同位语从句需用虚拟语气，其表达形式 为:should＋动词原形或直接用动词原形。这类名词常见 的有：advice，suggestion，proposal，order， demand，desire，request，requirement， recommendation, aim, wish, necessity, preference, motion, plan，idea，resolution。 We are all for your proposal that the discussion be put off. 我们都赞成你提出的将讨论延期的建议。 The suggestion that the mayor present the prizes was accepted by everyone. 由市长颁奖的建议被每个人所接受。
3. wish的用法 (1)wish后面的从句，表示与事实相反的情况，或表示将来 不太可能实现的愿望时，其宾语从句的动词形式为：
情况 主句 从句
从句动作先于主句动词动作
现在时
过去时
从句动作与主句动作同时发生 过去时/现在 过去完成时 时 Would 将来不大可能实现的愿望 将来时/现在 /could +动 时 词原形
【点拨】 ①若某人宁愿自己做某事，would rather后用动词原形。 I would rather stay at home today.
我今天宁愿待在家里。
I would rather stay at home than go out today. 我今天宁愿待在家里也不愿出去。
2.在表示命令、建议、要求等动词后面的从句中，像order, suggest, propose, require, demand, request, insist, command, insist+（should） do。 I suggest that we （should） hold a meeting next week. 我建议下周召开个会议。 He insisted that he （should ） be sent there. 他要求被派到那儿去。 【点拨】 如果suggest, insist不表示“建议” 或“坚持要某人做某 事”时，即它们用于其本意“暗示，表明”、“坚持认为” 时，宾语从句用陈述语气。 （错） Your pale face suggests that you （should）be ill. （对） Your pale face suggests that you are ill. （错） I insisted that you （should）be wrong. （对） I insisted that you were wrong.
I wish you wouldn‟t leave your clothes all over the floor. 我真希望你不把衣服丢得满地都是。 I wish that he had not made so much fuss about it. 但愿那时他对这件事不那么大惊小怪的。 I wish that the rain would stop. 要是雨停就好了。 (2）在“it is wished that”句型以及作名词所引起的表语和 同位语从句中也要求使用虚拟语气，用法同上。 (3)wish to do；wish sb./sth. to do I wish to see the manager. = I want to see the manager. 我希望见一见经理。 I wish the manager to be informed at once. =I want the manager to be informed at once. 我希望经理能马上得到消息。
3.连词otherwise, or, but He would have given you more help, but he has been so busy. 他本来可以多给你一些帮助的，只是他太忙了。 Seize the chance, otherwise you would regret it. 如果不抓住这个机会，你会后悔的。 He felt very tired yesterday, or he would have helped you. 他昨天觉得太累了，不然他会帮你的。
2.介词及介词短语:but that, but for, without, with, under, under ...condition, supposing, suppose, on condition that, in the past等。 Without your help, I couldnt have achieved all this. 要不是有你帮助,我不会取得这些成就。 But for the fog we would have reached our destination long ago. 要是没有雾的话，我们很早就到 目的地了。 Under more favourable conditions we could have finished the task. 如果条件对我们更有利，我们就会把工作完成得更好了。
四、虚拟语气在宾语从句中的运用 1.虚拟语气用在would rather，would（just）as soon， would sooner，would prefer（希望）等后接的宾语从句 中。 表示某人宁愿让另一个人做某事，其后的宾语从句的谓语动 词需用虚拟语气。若表示现在或将来要做某事，从句谓语动 词需用一般过去时;表示过去已经做的事，从句谓语动词用 过去完成时。 The manager would rather his daughter did not work in the same office. 经理宁愿她女儿不与他在同一间办公室工作。 Wouldn‟t you rather your child went to bed early？ 你不愿让你的孩子早点上床吗？
1.If she were to lose her place, they would be ruined. 2.If you were to speak to him, it would carry more weight.
二、混合条件句(错综时间条件句)
有时，主句与从句的动作发生在不同的时间，主句和从句谓 语动词的虚拟语气形式因时间不同而不同，这种条件句叫作 混合条件句。
过去 完成 时
would/shoul d/could/mig ht+have done would/ should/ could/ might/ ought to+动 词原形 would/ should/ could/might/ ought to+动 词原形
对将来 不大可 一般 能发生 过去 的事情 时 的假想 与将来 事实相 were 反的假 +不 定式 设
2.虚拟语气用在方式状语从句中 在as if （as though）引导的方式状语从句中，常用虚拟 语气，表示“似乎，好像”的意思，其动词形式与wish后 接宾语从句中的形式相同。 He talks about pyramids as though he had seen them himself. 他谈起金字塔来，就好像亲眼见到过似的。 I feel as if we had known each other for years. 我感觉我们好像已经认识好多年了。 It looks as if it might rain. 看上去好像要下雨了。
