As can be clearly seen from the cartoon，the mahjong pieces occupy most part of the desk，while a book，an exercise book and a pencil box lie at the corner. This picture vividly tells us how poor the condition is for the child to study.

　　This phenomenon gives rise to a lot of negative effects. In the first place，while the parents are playing mahjong，they make a lot of noise，which disturbs the child's study. In the second place，the child will have no place to study if his parents spend all day playing mahjong. However，time is crucial for him to acquire the knowledge，because practice makes perfect. Last but not least，the child will learn to play mahjong from his parents. Just as the old saying goes，“Like father，like son”，so the child will abandon his study and be a gambler like his parents.

　　Serious as it seems，we can think of some measures to deal with the problem. To begin with，the government should make stricter rules to prohibit parents from playing mahjong. What's more，the parents should give up playing mahjong for their child’s sake.
