　　直陈语气一般用来表示所说的话是事实或提出疑问，广泛用于陈述句、疑问句、感叹句。祁使语气表示所说的话是请求、命令、指示或劝告等。虚拟语气表示说话人所说的话不是事实，而是一种假设、建议或主观愿望。虚拟语气在宾语从句中 1. 记住：这些动词后面接的宾语从句：表示愿望( wish), 建议(suggest, advice, propose, recommend) ，要求(demand, request, require, insist), 命令(order, command)等。
2. 除wish外，其它动词用should + do 构成, should 可以省略。3. wish接宾语从句有三种情况：
1) 现在：用过去式
2) 过去：用过去完成式 (had done)
3) 将来：用情态动词(would / could) + do在宾语从句中 1. I wish she would be on my side.
2. I wish I were 30 years younger.
3. I wish (that) you would get a good job.
4. He wished he hadn‘t done it.
5. He ordered that the students wash the clothes every week by themselves. 在宾语从句中 4. 记住：insist / suggest 各有两种意思，要用
不同的语气。
Insist 表示“坚决要求”时，用虚拟形式，即 should + do;
Insist 表示“坚称，坚持说”时，用陈述语气，表示事实。
Suggest 表示“建议”时，用虚拟形式。
Suggest 表示“表明、暗示”时，用陈述语气。The teacher suggested that we (should) clean the blackboard after class.
His pale face suggests that he is ill.
He insisted that all of us should be there on time by any means.
He insisted that he was right.在宾语从句中 5. 在would (had) rather(宁愿) 引导的宾语从句中.
当从句表示现在或将来的时间时,谓语动词要用一般过去时; 表示过去时间时,谓语动词要用过去完成时。I would rather he came tomorrow than today.I would rather he liked English.
I would rather he had not told me the bad news.在主语从句中 在句型 “It is important (necessary, strange, natural) that ... ” 中，that 后面的从句中的谓语动词用： should + 动词原形.
1. It’s necessary that we should have a walk now.
2. It’s natural that she should do so.
3. It’s important that we should take good care of the patient. 主句的主语常是表示说话人愿望(wish / desire)、建议(suggestion / advice) 要求(requirement / demand)、命令(order, command)等的名词，表语从句的谓语动词用 (should) + do.

一、as if 连接表语从句

二、as if 连接让步状语从 句

2. It’s (high/right) time that…that 从句要用虚拟语气：谓语用过去时或should + do
It’s time that you left here.简单的归纳1、表示说话人的要求、建议、命令时，常用(should) do表示虚拟形式, 主要用于名词性从句中。
