when it comes to后面加什么

可加动名词doing，或名词,因为这个to是介词。例如When it comes to dancing,I&39;m all thumbs。谈到跳舞,我真是一窍不通。

when it comes to用法

when it comes to当涉及某事(或做某事)时

When it comes to something or when it comes to doing something means when it is a question of something or doing something.

Here "to" is a preposition.

(注意：这里 "to" 是介词)

例如：

1.When it comes to getting things done, he&39;s useless.

一涉及做事，他便不中用了。

2. Toddlers are notoriously antisocial when it comes to sharing toys.

众所周知，刚学会走路的孩子不愿和别人分享玩具。
