Today, there are many problems between parents and children. Many people always ask, “why do we often argue?”
Parents show their love for their children in different ways. They cook nice food, buy new clothes for them. They also care about their studies. Parents always say, “You must work hard.” “You should do your homework.” Or “Why not review(复习)for your exam?” all the time.
When children get bad marks, their parents get very angry. They often stop their children watching TV, playing games or even going outside until they make progress. Why? Most families have only one child. The child is the hope of the family, they want the child to be the best.
Many teenagers want to do things themselves. They want to do many unusual and special things that parents dislike. They like pop songs, basketball and other new things. They enjoy surfing on the Internet and playing QQ games. They spend a lot of time chatting online and listening to the QQ music. In their parents’ eyes, these are a waste of time. For these reasons, parents and children can’t get along with each other.
