have problem后面跟动词的什么形式？

Question

如题所述

Answer 1

have problems 后面的动词要用 ing 形式，比如
My English is so poor I often have problems understanding what the teachers says.
It's so noisy here that we have problems hearing the announcement.

have problems 要接名词短语，所以用 动词+ing 形式。
注：problems 有 s 。

我是加拿大人，英语是我第一语言。

Answer 2

此时problem后面常有介词of，说明怎样的问题，或者做什么方面出的问题。of提示后面如果要接动词，动词就得变成动名词形式，即词尾为-ing。追问

假如没有of呢？
