have has had是怎么回事,什么样子时在用什么?is are（was,were）呢? 用“have,has,had,there is,there are,there was,there were”填空. 选用“have,has,had,there is,there are,there was,there were”填空. 英语中is \was\ were\ be\ are\had\have\done分不清楚啥时候用何时使用BE【am/is/are/was/were/has（have）been】? 在英语中,什么时间用was/were,什么时候用have/has been? 用（is,are,was,were）造句英语中am,are,is,was,were,there is,there are,has,have,does,do 的主 has 和had,was ,were这些都是什么形态英文语法我想请问 are is be was were have had in on at of for to 这些词的助动词怎么用?is am are was were分别用在什么时候``有什么区别``? 英语语法.动词前的have/had,have/had been,was/were都分别用在什么时候/环境啊?
