有關(guān)be動詞、情態(tài)動詞和實義動詞的區(qū)別(文件)
【正文】 ③ She wants to be a teacher. （變?yōu)榉穸ň洌鶶he doesn’t want to be a teacher.④ They like to play basketball. （變?yōu)榉穸ň洌鶷hey don’t like to play basketball.(3)一般疑問句：Do/Does +主語+動詞原形+其他？句中加了do/does后，其后面的動詞還是必須用動詞原形。（1）肯定句：① I have a blue book.② He has a brother.③ She wants to be a teacher.④ They like to play basketball.(2)否定句：主語+don’t/doesn’t+動詞原形。也就是在含有實義動詞的句子變否定句或疑問句時，一定不能用be動詞。①I can spell my name.(變否定句)→I can not(can’t)spell my name.②He can swim. (變否定句)→He can’t swim.(2)變一般疑問句：Can + 主語+ 其他？即直接把can提到句首。情態(tài)動詞后面必須接動詞的原形。即，直接在be后not.①I’m a Chinese boy.(變?yōu)榉穸ň?②You are good. (變?yōu)榉穸ň?③
