what do you do?

Question

如题所述

Answer 1

1.What do you do ?
这是特殊疑问句 疑问代词what 作宾语
第一个do是助动词 构成疑问句 因为主语非单三 故 用do
第二个do 是 代动词 代表一切行为动词 是动词原形
本句 是对 谓语部分 提问的 特殊 疑问句 注意 不仅仅是提问宾语2.How many lessons do you have every day？不可以说成How many do you have lessons every day？因为how many 是作定语的 这样会 多宾语如果 用how many 的活 原句的 lessons 也应去掉 说成How many do you have every day？how many 起代词作用 作宾语
3.What does he do in the afternoon ？不可以说成What does he in the afternoon？因为 不合语言规则 does 是助动词 不能单独作谓语 如果是行为动词 则 多主语 可以 who does something in the afternoon?
4.They don't do their homework in the morning。不可以说成They don't their homework in the morning。行为动词的否定形式 是 don't/doesn't 加动词原形
