如果你要在“anytime”和“any time”这两个词之间做出选择，有趣的是，在一个世纪之前，你甚至没有选择的余地。那时，人们在写作时，总是使用两个词的版本。没有“anytime”这个词，它是近代产生的缩写，然后被采用。

如何使用“Any Time”

“any time”是一个名词短语，意思是“没有特定的时间”或“任何时间”。它表示某件事可能很快就会发生，但不能说出确切的时间。“Any time”应该写成两个单词，当它作为状语从句时，前面要加上“at”。例子:

The package is due to arrive at any time.

Because tensions between the two countries are high, violence could erupt at any time.

It is also written as a two-word phrase when "any" is used to modify the word "time" in sentences such as:

I won’t have any time to work on the project until next week.

If you have any time available, I'd love to meet for lunch this week.

“Any time”用两个词来写总是正确的。在正式写作中，它应该总是写成两个词。

如何使用“Anytime”

“anytime”这个词是随性的缩写，它是一个语法错误的词被广泛使用的结果。“Anytime”是副词，意为“无论何时”或“毫无疑问”。它只在用作副词时才正确。例子包括:

You can call me anytime.

The boxer said that he could defeat his opponent anytime.

随著“随时”等随性用语在口语中越来越常见，它们也经常出现在非正式的写作中。然而，它们不应该用于正式的写作中。韦氏词典将“anytime”一词的最早使用时间追溯到1822年。

例子

下面是一些使用“anytime”和“anytime”的例子，包括一些不正确的版本来帮助你看出区别。

Correct -We can leave anytime you're ready to go.

Correct- We can leave any time you're ready to go.

Correct -The smoking volcano could erupt at any time.

Incorrect- The smoking volcano could erupt at anytime.

Correct -The guest speaker didn't have any time to go over his notes.

Incorrect- The guest speaker didn't have anytime to go over his notes.

Correct- Because the cab driver took a wrong turn, we didn't have any time to say goodbye.

Incorrect- Because the cab driver took a wrong turn, we didn't have anytime to say goodbye.

如何记住它们的区别

一个帮助你确定在非正式写作中使用“anytime”是否合适的小技巧是，在不改变句子意思的情况下，用“whenever”来代替它。如果是这样，你可以自信地认为你已经正确地使用了它。

你也可以试着用另一个副词如“愉悦地”或“安静地”来代替“任何时候”。如果这个句子在语法上仍然正确，那么使用“anytime”应该是安全的。例如:

I play my guitar anytime.

I play my guitar cheerfully.

I play my guitar quietly.

“Any time”既可以作为名词短语，也可以作为副词短语。“Any time”总是正确的。“Anytime”总是副词。“Anytime”不能跟在介词“at”后面。当提到一定的时间时，使用“any time”。不要在正式写作中使用“anytime”。
