Dad was on business and Mom went to the supermarket. I was lonely①at home.“Wow,”I said to myself,“it’s time for me to enjoy the good times today!”So I began to play football at home after finished②my homework. Suddenly, I kicked the ball so hard that it hit a vase and broke it. It was my mom’s favorite. I decided to tell my mom it was the fault of the cat because I was afraid she will③come back and beat me. Two hours later, mom got home. However, on second thought, I told my mom what true④happened. Instead of beating me, Mom said to myself⑤,“Honesty is the most important thing and I hope you can learn to be honest even when no one sees what happens.” I would never make such a foolish mistake.展开更多
