But before I knew it,I was taking part in local races. 但是没过多久,我就开始参加本地的比赛了。
名师点拨
本句是一个主从复合句。主句是 I was taking part in local races；before 引导时间状语从句。before I know it 意为“转眼之间,一下子”,类似的表达还有 before you/we know it 等。如：
Focus on your performance rather than the audience — I can assure you that your tension will disappear before you know it. 专注于你的表演而不是观众——我可以向你保证,你的焦虑很快就会消失。
微语法填空
To interpret (interpret) how to live more with less to my son,I persuaded him to do (do) an experiment with me. We decided to play with only one red plastic ball — simple,readily (ready) available — for as long as it would keep our interest.

My son did get inspired/inspiration (inspire) from my experiment to find (find) joy in simple things and said to me,“Dad,simplicity actually can lead to great happiness,right?”
