请翻译"我们过去用过这东西，现在不用了"

we uesd it before,but not now.

We used to use this stuff, but it has fallen into disuse.

We used to use these things.
这应该是辨析used to do和used to doing吧

what we used in the past was not used any more

we have been used this,but now we can't.

this is what we used to use,but we don't use it now.
