为了帮助考生们更好地备战雅思考试，出国留学网雅思栏目为您带来“解读雅思口语考试中的虚拟语气”，希望对大家有所帮助!
虚拟语气在宾语从句中的用法
1.用在动词wish之后
在动词wish后的宾语从句中，从句动词用过去时表示与现在事实相反的愿望;从句动词用过去完成时表示与过去事实相反的愿望;
从句中用 “would/could+动词原形”则表示将来难以实现的愿望。
I wish I knew how to operate the machine.
我要是会操作这台机器该多好啊。
We wish you had come to our English evening.
我们真希望你来参加了我们的英语晚会。
I wish I would try again.我真希望能再试一次。
注意：wish与hope的区别
wish后的宾语从句要用虚拟语气，而hope后的宾语从句要用陈述语气
I hope you'll be better soon.
我希望你能很快好起来。
2.用在would rather/would sooner后的宾语从句中
would rather和would sooner可以后接一个有自己的主语的宾语从句，从句内容是宁愿他人做什么或宁愿某物怎么样。
这种宾语从句中用过去时表示现在和将来的虚拟内容，用过去完成时表示过去的虚拟内容。
I wish I had seen you yesterday.
我希望昨天能见到你。
I'd rather you went home now.
我倒宁愿你现在回家。
I would rather you came tomorrow.
我倒宁愿你明天来。
I would rather you had stayed at home last night.
我倒宁愿你昨天晚上呆在家里。
3.用在表示命令、建议等意义的动词后的宾语从句中
在表示提议、要求、命令、意愿、决定等意义的动词
(如suggest, decide, require, request, demand, propose, insist, order, prefer等)
后的宾语从句中，常用 "should+动词原形"，should常被省略。
The experiment has failed.
实验失败了。
I suggest you try again.
我建议你再试一次。

几乎他所有的朋友都建议他去拜访约翰逊先生。
