did do does doing done哪两个是非谓语动词. 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 do did doing does done 是不是有一些不是动词吖 不能直接做谓语 do did does是不是可以直接做谓语 但done doing不能直接做谓语 have done be doing才 doing done这两个不是动词吧 是非谓语动词吧 done 和 doing不是动词吧 是非谓语动词吗 模仿下列词写出下列动词的变化形式 do-doing-does-did-done(英语） 提问动词用what……do/done/doing 为什么不用did 可不可以what does do did does done doing这几个都是由do变化的那这里哪一个不是动词doing done究竟是动词还是 英语句子中do／does／did不是动词吗?再加谓语不就有两个动词了么 do did does done doing这几个都是单词吗 非谓语动词,doing to do done 的用法区别
