高中英语 虚拟语气讲解及练习(有答案)
高中英语虚拟语气讲解及练习虚拟条件句就是对现实条件的一种虚拟假设，所假设的条件一般不符合事实或与事实相反或在现实中发生的可能性极小。
根据时间的不同，虚拟条件句可分为三种，即与现在事实相反的虚拟条件句、与过去事实相反的虚拟条件句（1）表示与现在事实相反If I had enough money now, I would lend it to you.（2）表示与过去事实相反If he had taken your advice, he wouldn’t have made such a bad mistake.（3）表示与将来事实相反I would go shopping with you if it were to be Sunday tomorrow.1. 虚拟条件句的倒装在虚拟条件句中，为了强调所假设条件的虚拟性，或突出说话人的一种主观愿望，虚拟条件句可用倒装结构。
虚拟条件句的倒装是通过去掉if，把条件从句谓语中的助动词、情态动词或系动词放在句首实现的。
例如：Had I been（= If I had been ） in that situation， I would not have let the thief escape away with so much money.Should there be （= If there should be） a drought， what should we do at that time ？2. 错综时间条件句有时条件从句的动作和主句的动作发生的时间并不一致，这时谓语动词的形式应根据它所要表示的具体时间来确定。
例如：If we hadn’t been working hard in the past few years ，thing s wouldn’t be going so smoothly.3. 含蓄条件句有时假设的情况并不以条件从句的形式表现出来，而是通过某个介词或介词短语（如：with，otherwise，without，but for，in that position）、上下文或其它方式表现出来。

初中虚拟语气讲解及专项练习与答案(带解析)
虚拟语气讲解语气(mood) 是一种动词形式，用以表示说话者的意图或态度。
英语中的语气有三种：陈述语气、祈使语气和虚拟语气。
直陈语气(indicative mood),表示所说的话是事实。
祈使语气(imperative mood),表示所说的话是请求或命令。
虚拟语气(subjunctive mood),表示说的话不是事实，或者是不可能发生的情况，而是一种愿望、建议或与事实相反的假设等。
一. 虚拟语气在条件句中的应用学习虚拟语气在条件句中的用法之前我们必须清楚条件句的种类：条件句有真实条件句与非真实条件句(或称虚拟条件句)两种。
真实条件句所表的假设是可能发生或实现的，句中的条件从句与结果主句都用陈述语气。
如：If it doesn’t rain tomorrow, I will go for a picnic. 假若明天不下雨，我就去野餐。
Oil floats if you pour it on water. 你如把油倒在水里，油就浮起来。
虚拟条件句所表的假设则是不可能或不大可能发生或实现的，句中的条件从句与结果主句皆须用虚拟语气。
1. 与现在事实相反的虚拟条件句，条件从句的谓语用动词的过去式(be的过去式用were), 主句的谓语用should （would, might，could）+动词原形。
如：If it were not raining, we should go for a picnic.如果现在不下雨的话，我们就出去野餐了。
（事实是：天在下雨，我们不能出去野餐。
表示愿望。
）If he came here, he might be able to help you. 如果他来这，他就能够帮助你了。
（事实是：他没来这，他不可能帮助你。
表示对他的良好印象。
）2. 与过去事实相反的虚拟条件句，条件从句的谓语用had+过去分词，主句的谓语用should （would, might，could）+ have ＋过去分词。
