noeasyday

no是形容词，在句中作定语，表示否定，意思是没有或不是，可以修饰可数名词的单复数和不可数名词，相当于not a或not any，比如说：

see no reason，等于not see a reason，看不出任何理由。

There is no such disease. 等于There isn't such a disease，没有这样的疾病。

not是副词，通常位于be动词、情态动词、助动词之后，构成否定形式，意思是“不”，“没有”，它也可以位于动名词、不定式、分词（包括现在分词、过去分词）之前，构成否定形式，意思同样是“不”，“没有”。在省略结构里，not可以放在包括名词、动词、形容词、副词等的一切词类前面，表示否定，比如：

Tim isn't a young man.

He asked me not to be late.

Let's not go.

It seems not to be right.

Not having a vocabulary book is a serious problem.

Not having had anything for a whole day, he wolfed down three bowls of rice.

I need to have some meat because it has some minerals and vitamins not found in vegetables.

No, not tomorrow.
