现阶段be动词形式有: am, is, are, were, was, isn’t, aren’t, weren’t, wasn’t

助动词形式有: do, does, did, don’t, doesn’t, didn’t

※    1. 在英语句子中进行变化的时候, 有be动词的就在be动词上变化,变 “过去”, “否定”;

         否定                                   过去     否定

am-------am not(第一人称 “I” )           am, is ------ was --------- wasn’t

is ------- isn’t  (第三人称)               are  ------were --------- weren’t

are------aren’t  (you和其它人称)

2. 没有be动词的就要加助动词;

                     否定          过去     过去否定

do                -----don’t   ------did---------didn’t

does(第三人称单数)-----doesn’t ------did---------didn’t
