1、I.动词的语气简介：语气表示说话人对说话内容的看法的一种语法范畴。在英语中，可用不同的动词形式表示说话的语气。,动词的三种语气：1、陈述语气所表达的动作或状态是符合客观 现实的。e.g.Flowers blossom in spring.He played the piano well.,2、祈使语气表示号召、命令、请求、劝告等。e.g.Let us help you.Keep off the grass.,3、虚拟语气与事实相反，表达的是假设，愿望，怀疑或推测等。,II.虚拟语气的运用,1）if真实条件句 2）if虚拟条件句 3）错综条件句 4）省略if的倒装句 5）含蓄条件句（withou
2、t，with,but for,otherwise等后）,一、在if条件从句中的运用,二、其他形式的虚拟语气,1）表建议的advise，suggest等词的从句+（should）+动词原形 2）wish，would rather，as if等后的虚拟语气的形式,同学们首先要牢记它的三种形式,它将为学习此类句子奠定基础,一、if条件句中的虚拟语气,If it _(rain)tomorrow,our trip _(put off).,2）if虚拟条件句,构成从句：一般现在时 主句：将来时,rains,will be put off,动词过去式(bewere),条件从句谓语,主句谓语,would/sh
3、ould/could/might+动词原形,had+过去分词,would/should/could/might+have 过去分词,动词过去式 were+不定式 should+动词原形,would/should/could/might+动词原形,1）if真实条件句,与现在事实相反,与过去事实相反,与将来事实相反,练习：,1.If I _(know)her address,I would write to her.2.What would you have done if you _(miss)the train?3.If he _(not be ill),he would have done
