Unit21 Human Biology-语法篇____________________________________________________________________________________________________________________________________________________________________1、掌握混合条件句中的虚拟语气的用法||。
2、情态动词的用法||。
混合条件句中的虚拟语气混合条件句主句是指条件句中含有不同的条件结构||，谓语动词所表示的动作和条件从句谓语动词所表示的动作并不是同时发生||，如一个与过去事实相反||，另一个与现在事实相反||。
在这种条件句中||，动词的形式要根据具体情况进行调整||。
If you had followed the doctor’s advice (then)||，you would be all right now.如果你那时听了医生的话||，你现在就好了.(主句与从句发生的时间不同||，应按照主句与从句各自的时间做调整.)If you had watered them more||，the crops would be growing still better.如果你再给庄稼多浇些水||，他们会长得更好.(指现在长得更好.)If you had watered them more||，the crops would have grown still better.如果你早就给庄稼多浇些水||，他们就会长得更好(表示对过去的虚拟)情态动词一．定义情态动词是一种本身有一定的词义||，但要与动词原形一起使用||，给谓语动词增添情态色彩||，表示说话人对有关行为或事物的态度和看法||，认为其可能、应该或必要等||。
情态动词后面加动词原形||。
二．分类：情态动词有四类：①做情态动词：must||，can(could)||，may(might)||，ought to②可做情态动词又可做实义动词：need||，dare③可做情态动词又可做助动词：shall(should)||，will(would)④具有情态动词特征：have(had) to||，used to三．常用情态动词的用法1.must和have to表示必要性2.can’t表示不可能||，mustn’t表示不允许或禁止3.don’t have to和needn’t表示没有必要4.can 和could 表示能力和可能性||，还可表示请求允许5.must||，might||，could表示猜想和推测6.may表示可能和允许四．情态动词+have+过去分词1. “must+have+done”表示对过去事情的肯定推测||，译成“一定做过某事”||，该结构只用于肯定句||。
