Question

“do you want to be my friend”改成肯定句是什么？

Answer 1

“do you want to be my friend”改成肯定句是 “I  want to be your friend。”

否定句：在谓语动词前加助动词don't，如果是第三人称单数作主语，则在谓语动词前加doesn't；如果是系动词Be，则根据人称，直接说aren't 或isn't。

如：We go to school every day.改为否定句为： We don't go to school every day.

He goes to school every day. 改为否定句： He doesn't go to school every day.

We are workers. 改为否定句： We aren't workers.

He is a student.改为否定句：He isn't a student.

I am a student.改为否定句：I'm not a student.

一般疑问句：把助动词或系动词be放于句首。

如：Does he go to work every day?

Do you go to work every day?

Is he a student?

Are you workers? 

Are you a worker?
