I live in a village by Mekong River. Every day, like most of my friends, I walk to school. It is three kilometres away. After class, I often help my mother to collect water from the river and feed the chickens. At the weekend, the villagers often gather at the community hall where there is a TV. The adults watch TV, but more often they talk about their farm work and exchange news. The children run around, playing games and shouting merrily. Laughter is heard everywhere. My father sometimes takes me to the market town nearby where he sells our home products like vegetables, fruits, eggs… He then buys me an ice cream and lets me take a ride on the electric train in the town square. I love those trips. On starry nights, our children lie on the grass, looking at the sky and daring each other to find the Milky Way. We dream of faraway places. True False 1/ The boys helps his parents to collect water from the village well. 2/ The villagers gather at the community hall at the weekend. Answer the following questions. 1/ Does the boy like riding on the electric train in the town square? 2/ What do the children do on starry nights? 3/ Do you like to live in the countryside or in the city ? Why? lý do nữa nhé
