请问，Can you help me to answer some questions中 为什么+to？

Can you help me answer some question？ 的句式对么

can you help me to answer some questions?

Can you help me for some queestions?
How many people are there in Beijing?
Is Hong Kong bigger than Beijig?
Is it hotter in Hong Kong?
Is Hong kong older than Beijing?

to answer some questions 是不定式作宾语补足语
但是help后面的不定式的to可用可不用

Can you help me to answer some questions？
=Can you help me answer some questions？

to 其实可以省略。
解释：help sb. (to) do sth 表示“帮助某人做某事”。to 可以省略。

祝你学习进步，更上一层楼！请记得采纳，谢谢！(*^__^*)

因为help 后面 跟动词不定式

help somebody to do something. 固定用法。

固定搭配help/sb/to/sth=help/sb/doing/sth.

help sb to do sth 和help sb do sth 这两种用法都是可以的。
希望对你有帮助哈~
