My name is Li Mei. I'm 13 years. There are three people in my family they are my father, my mother and me. My father is a farmer. In the past, he got the crops in by hand. Now he uses a machine. It can get the crops in very quickly. It can save a lot of time. My mother is a street cleaner. In the past, she swept the streets with a broom. Now she drives a street sweeper. It can clean the streets in a short time. My home is far from my school. I went to school on foot five years ago. Now I go to school by bus every day.
