Do、done、did后面的动词不变对吧? do did does doing done人家都说这几个是动词 那为什么有两个不能做谓语吖 疑问句有实义动词时除了用do does did done 可不可以用情态动词 do是动词原型 did动词过去式 done是动词的过去分词 doing是现在分词 都对吗 do did doing does done 是不是有一些不是动词吖 不能直接做谓语 提问动词用what……do/done/doing 为什么不用did 可不可以what does 英语句子中没有实义动词是不是要加am is are有实义动词是不是要加do did done does do的过去式“did”后面的动词恢复原形吗 would do but do 和would have done but did does do did done 这四个单词分别在什么时候使用? 例句：All you have to do is (to) press the button.若主语有个实意动词do用作表语的不定式可省to若那个实意动词是does,did,done,don't,do not……那么可省to吗? 模仿下列词写出下列动词的变化形式 do-doing-does-did-done(英语）packleavecutknowasktypelookhavegoshopcallclimbskifly求大神解答 谢谢!急
