In nowadays,it is commonly believed that our children should receive formal education as early as possible,thus many parents start teaching their children textbook knowledge when the children are only two or three years old.However,does the child really need formal education that early?As for me,the answer may be negative and there are two main reasons that I will outline below.
First of all,as we all know that the games is children’s nature,and by playing games children can develop various kinds of abilities which are especially important for them in the future.For example,a child may acquire the sense of team spirit and the ability of leadership through playing team games with other kids,such as basketball and football.When they are playing these kinds of games they have to corporate with each other and to listen to the leaders of their team to win the games and this is quite the same as their work in the future.
Secondly,games can dramatically improve both physical and mental health of our children.As we all know that the children who always play outdoor games are tend to be stronger than those who are used to stay at home.Because when they are playing on the ground,it is necessary for them to run and jump and these movements are extremely important to maintain physical health.So it is clear that if we hope our children have stronger body,we have to let them play outside.Besides,Taking part in a variety of games can make our children have a happy childhood which is a precious memory to them when they grow up.
In conclusion,I strongly suggest that we should let our children play instead of study among theirs early years of life.Because they can both learn useful skills and grow up healthily through the games.
