Where have you been,Alice 为什么用been Alice opften helps do some cooking after work.为什么用do

Where have you been,Alice 为什么用been Alice opften helps do some cooking after work.为什么用do
（1）因为alice已经回来了,所以用been,意为你去哪了?或你去过哪了.
（2）do some cooking 是固定搭配,因为help是单数第三人称,所以do为原型.

Where have you been,Alice ? 是问她去过那里？用现在完成时。
Alice opften helps do some cooking after work.是经常性发生的动作，用一般现在时

你好。很简单
help sb (to) do sth------(to) do sth做宾语补足语
help (to) do sth------do与help一起做复合谓语

完成时，所以用have been；
help sb do sth,固定搭配
