2、9thecompanybuilttheGlobeTheatre.经过前面的学习,我们知道大多数动词的过去式的变化规律为:“动词原型+ed”但是在英语中不符合上述变化规律的动词也很多,它们有其特殊的变化形式。这种动词称为不规则动词。这种动词的变化没有规律,而要靠同学们单独记忆。下面将常见的不规则动词的过去式总结如下:要牢记喔!一般过去式(III)Grammar1.不变:cost-cost;hurt-hurt;put-putlet-let;read-read2.只变一个元音字母:come-came;become-became;b

7、看。行为动词的一般过去时变一般疑问句时,有三个要点:一、句首加did,动词还原。二、将句中的第一人称变为第二人称。三、some变any;already变yet。巧记动词过去时态动词一般过去时,表示过去发生的事;be用was或用were,have,has变had;谓语动词过去式,过去时间坐标志;一般动词加-ed,若是特殊得硬记。否定句很简单,主语之后didn’t添;疑问句也不难,did放在主语前;如果谓语之前有did,谓语动词需还原;动词若是was,were,否定就把not添。【总结】WearrivedinShanghaila
