动词分类+一般现在时（一）一、动词分类动词是英语词类中最重要的一种。
动词按其词义和在句中的作用可分为：及物动词实义动词不及物动词系动词动词情态动词助动词1.实义动词(有实际意义的动词，可在句中独立做谓语)：及物动词可以直接加宾语（study/ learn/ eat/ drink/ wash…）不及物动词不能直接加宾语，但是不及物动词+介词+宾语（常见动词有：listen to/ look at/ speak to…）2.系动词+形容词1）感官动词：feel; sound; smell; taste; look +形容词（当look 做实义动词讲时为不及物动词）2）be/ seem+形容词3）表变化的词：get/ turn/ become/ go+形容词（get/ turn/ go当实义动词讲是意思分别为：得到/ 轮流/ 去、走）3.助动词无实际意义，在句中不能独立做谓语，have/ do 既可以做助动词也可以做实义动词（先做简单了解，之后讲动词时态时会经常见到）eg1. I have a bike. (have是实义动词)eg2. They have gone to Beijing. (have是助动词)eg3. I do my homework everyday. (do 是实义动词)eg4. I do like English.
