cannot(can’t的全写)

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的展开形式。

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也可以展开为can not(两个单词)，但是这种写法比较少见，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.)

这样更具有强调性

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有时也只是因为各自的搭配而碰巧挨到一起。

For example:

Kevin can not only rap but dance too.

凯文不仅能饶舌也能跳舞。

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

在这里，can not必须写成两个词，并不是can’t的展开形式。

◆◆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的展开形式时，是可以互相取代的。

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cannot。值得注意的是，许多拼写检查软件甚至高亮显示can not作为错误的拼写。

◆◆Can Not 用于强调◆◆

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

只有当not被用于强调时，你才需要考虑用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.

用两个单词的写法来使not的强调意思更加清晰明了。通常用在感叹句中，也就是结尾有感叹号的句子。

◆◆

It is possible to see can and not as two separate words, especially with the correlative conjunction not only…but also.

Danielle can not only cook but also bake.?

丹妮尔不仅会做饭，而且会烤面包。

My dog can not only roll over but also play dead.?

我的狗不仅会翻身，还会装死。

In these examples, cannot is not an option.
