Traffic safety(交通安全) is everybody's business. We must obey（遵守） the traffic rules. For example, we must walk on the sidewalk. When we cross the zebra crossing（十字路口）, stop and look left and right, then go across fast. Don't play football on the road. Don't chase（追赶） and fight on the road. When we are in a car, we must put on our seat belts(安全带).Then lock the doors. Don't throw things out of the window.
We can tell our parents "Don't drink before driving. Don't run through the red lights. Don't talk or laugh while driving.
Only everybody thinks traffic safety is everybody's business(事情), everybody will be safe.
My life has changed a lot in the last few years. My daily life is different and I used to like different things when I was a child. I didn't use to like tests. Now, I don't mind them. I didn't use to like English, now is my favorite subject. I used to like playing tennis. Now, I like swimming and playing ping-pong. I used to have curly hair, now I have straight hair.
I used to be short. Now I'm a little taller. I used to be really quiet, now I'm outgoing. I used to be afraid of speaking in front of a group. But I don't worry about speaking in front of a group. Maybe, I will change more!
