直接做定语修饰后面的名词/代词时,只能用 no,不能用 not;
比如:There is no student in the classroom.
= There isn't a student in the classroom.
There are no students in the classroom.
= There are not any students in the classroom.
如果是使用助动词否定形式来构成否定句时,或者直接用在非谓语动词前面表示否定时,只能使用 not,而不能使用 no;
如:I did not finish any homework.
= I finished no homework.
I will not attend the meeting if not invited.
= I won't attend the meeting if I'm not invited.
