在句子中表达否定时一般用not,比如 He did not go to school yesterday; You can come tomorrow,but not on Friday; Ask Jessie,not jesse.
no 在句子中一般是 no + 名词 (noun)或 名词性动词 (动词+ ing形式),意思是‘ not any’,例如:No man is perfect; No one like him.
在有的句型,动词+not 与 no + noun 有相似的意思.比较下面两个例句的表达方法:
He has got no friends ;
He has not got any friend.
希望能帮到,good luck!
