whether 后可以接动词不定式吗？

请大家帮忙看下面是否翻译正确，并且whether 后可以接动词不定式吗？;我想知道今天下午是否有会，有几场会？I want to know whether to have a meeting in this afternoon and how many meetings?

whether可以引导不定式。

首先，不是这不是一个疑问句，应该用句号。

其次，后面的句子不完整

I want to know how many meetings?

应该是

I want to know how many meetings I have.

所以整个句子该是

I want to know whether to have a meeting in this afternoon and how many meetings I have.
