In our life,there are many great inventions,such as the light,the pencil,the bag...At the age of 6,my father brought a car,he took me to school on the first day of school.It was so exciting.I fell in love with this invention on that day.The car can go anywhere and save time,but it also pullutes our environment.I holp I can invent clean cars.I hope the cars will enter every family,and I love cars best.
