是it's time for us to do some shopping,还是it's time for us do some shopping
是it's time for us to do some shopping.

it's time for sb. to do sth. 某人该做某事了, 这是固定结构,

因此要用不定式to do some shopping.

it's time to do sth 做某事的时间到了
for us是个插入语，可以不去理会
正确的应该是it's time for us to do some shopping 我们购物的时间到了

It's time for us 【to】 do some shopping.
It's time for sb to do sth到某人该做某事的时候了

希望帮到你
