1 an occasion when you tidy a place by getting rid of things that you do not want -- 清理(清除某地不用之物使之整洁)
We need to give the garage a good clear-out. 我们需要把车库好好清理一下。
We can complete it step by step however long the road is and it can't be completed however short the road is if you don't even mark your footprint.
再长的路,一步步也能走完,再短的路,不迈开双脚也无法到达。
