The Quick Answer

Cannot (one word) is the most common expansion of the contraction can't.

cannot(一个单词)是缩写can't展开形式。

Can't can also be expanded to can not (i.e., two words), but this is less common and usually reserved for emphasis.

Can't也可展开为can not(两个单词)，但这种写法很少见，有时只是为了强调。

For example:

I cannot do it!

(Can't is usually expanded to cannot.)

Can't通常展开为cannot

I can not do it!

(This is considered more emphatic.)

这样更强调

Of course, the words can and not sometimes appear alongside each other when the not forms part of another construction (such as not only).

当然，can和not有时只是因为各自的搭配而碰巧在一起。

For example:

Kevin can not only rap but dance too.

凯文不仅会饶舌，还会跳舞。

(Here, can not must be written as two words. It is not an expansion of can't.)

在这里，can not必须写两个字，而不是can't展开形式。

◆◆Cannot or Can Not?◆◆

Cannot and can not are interchangeable as expansions of the contraction can't.

cannot和can not在作为can't展开形式可以相互替代。

However, the modern preference is to use cannot. Of note, many spellcheckers even highlight can not as an error.

然而，在现代，人们更倾向于使用它cannot。值得注意的是，许多拼写检查软件甚至突出显示can not拼写错误。

◆◆Can Not 用于强调◆◆

You should use can not over cannot when the not is emphasized.

只有当not当你被强调时，你需要考虑它can not而不是cannot

For example:

I can not tolerate laziness!?

我不能容忍懒惰

The two-word version makes it clearer that the word not should be emphasized. This is most useful in an exclamatory sentence, i.e., one that ends in an exclamation mark.

用两个单词的写写作方法not强调的意思更清晰。通常用于感叹句，即结尾有感叹号的句子。
