语气的定义和种类(1）语气的定义语气是动词的一种形式，它表示说话人对某一行为或事情的看法和态度。

（2）语气的种类A. 陈述语气表示动作或状态是现实的、确定的或符合事实的，用于陈述句、疑问句和某些感叹句。

We are not ready.Did it rain all day yesterday？What a fine day today!B. 祈使语气表使说话人的建议、请求、邀请、命令等。

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）, 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。

虚拟语气一、语气的分类语气概述：语气，跟失态和语态一样，也是动词的一种形式，表明说话者的意图、态度和目的。

英语中有三种语气：陈述语气、祈使语气和虚拟语气。

1.陈述语气：用来陈述事实或提出想法，包括肯定、否定例：Recent pressure at work may account for his behaviour.他的行为也许是最近的工作压力导致的。

2.祈使语气：表明说话人提出请求、命令或劝告等例：Calm down and tell me what happened.冷静点儿，告诉我发生了什么事。

祈使语气也可用在并列句中表示条件Work hard and you will succeed.好好干，你会成功的。

H e quick or you’ll be late.快点儿，否则你会迟到。

3.虚拟语气：表示说话人的一种愿望、建议、请求、命令；有时是一种非真实的假设，与事实不符或相反的情况例：If had seen him yesterday, I would have told him the news.我如果昨天见到他，就会把这个消息告诉他了。

二、虚拟语气的用法（一）虚拟语气在条件句中的应用1.虚拟语气主要用在虚拟条件中，表示根本不存在的情况或可能很小的假设虚拟语气用于if条件句中时，主句和从句谓语动词的形式如下：——与现在事实相反：过去式（be一般用were）should/ would/could/might+动词原形——与过去事实相反：had+过去分词should/ would/ could/ might have +过去分词——与将来事实相反：过去式（be一般用were）/should + 动词原形/ were to + 动词原形should/ would/ could/might + 动词原形例：If I had enough money, I would buy myself a computer.我如果有足够的钱，会为自己买一台电脑。

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。
