英语is的句型小学

is是be动词的第三人称单数，用在形容词前及没有动词的句子中。注意，是第三人称单数作主语的句子！第一人称用am，第二人称用are。do是助动词，也可作动词“做”讲。前面老兄说的“do homework”就是的，意思是“做作业”。一般的，do用在句型中，意思是动词。比如“make sb. do”当然，一般的句子中是助动词，用在不是情态动词及be动词的否定。这是最常见的。比如“不要讲话”，这个祈使句，“Don't talk”就是的。孩子英语不好是上课的原因啊！上课要活泼的！不能太活泼啊。还有，不会的要问英语老师，还是他们了解孩子。到网上问不好啊，这三言两语讲不清啊！还是要问老师的好啊！

is=是(第三人称）：He is a teacher.（他是一位教师。）一般现在时is---过去时was,were---现在完成时beendo=做： I am going to do my homework.（我将要做我的作业.)
