英语中怎么把肯定句变成疑问句、否定句？

如题

Answer 1

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?不知对你是否有帮助？

Answer 2

助动词，或者be动词提前，其余不变。如果变否定句：就在助动词或be动词后直接加not
