I like you.和 I do like you.有什么区别 do是助动词吗?助动词不是没有实际意义吗,为什么有时用 问句中出现动词就一定要跟上助动词吗?为什么?Do you like this dog?和Would you like c what do you like?do是结构词么 助动词? Do you like to do sth?为什么回答是Yes ,I do.不是Yes,I like. Yes I do.Do you like biscuits?Yes I do 为什么回答的是I do,不是I like, 那Do you like?中 do作为助动词的话 回答时 Yes i do 中的do也是助动词?还是作谓语如果作为谓语那 为什么要用助动词?我一直弄不明白为什么要有助动词,如do,I do not love you.到底什么时候必须用助动词? do you like shopping 和do you like going shopping有什么区别吗,具体点 什么是助动词Did you like the film?中的DO是不是助动词 怎样用助动词do?l like orange.改为问句是不是 Do you like orange would you like句型中would既然是助动词,那i would句型中的这个would是否也是助动词? Do you like salad?回答为什么是yes,I like.而不是 yes ,I do.
