Question

It's snowing hard.Let's go＿＿（ski）outside.

I often hear the girl＿＿（sing）songs in the next room.

Answer 1

The swimming pool ＿isn't open＿（not open） today.We can’t go swimming
不要用被动语态，表示状态，等lz有了语感会变得很容易的，
举例
the perfume smells good香水闻上去好好啊
the window is open窗户开着

It's snowing hard.Let's go＿skiing＿（ski）outside.
go+doing形式，去干某事

I often hear the girl＿sing＿（sing）songs in the next room.
hear sb do sth表示“听到某人做了某事”，hear sb doing sth.表示“听到某人正在做某事”，一些感观动词如hear, see, feel, watch等后面既可以接宾语+do sth, 也可接宾语+动词-ing形式构成复合宾语。根据情景及句意的需要许多时候只能用一种，但有时两者都可用而意义没多大区别。
