题目内容
If parents’ aim(目标) is only to make a child be a genius(天才), they will cause a disaster. Several leading educational psychologists(心理学家) say this is one of the biggest mistakes that can cause great problems to children.
However, if parents are a little gentler, the child may act successfully—especially if the parents can support him. Michael Li is very lucky. He is very fond of music, and his parents help him a lot by taking him to concerts and inviting a teacher to give him personal piano lessons. They even drive him 59 kilometers twice a week for violin lessons. Although Michael’s mother knows very little about music, Michael’s father plays the piano very well. However, he never makes Michael enter music competitions if he is unwilling.
Michael’s friend, Winston Chen, however, is not so lucky. Although both his parents are successful musicians(音乐家), they set too high a standard for Winston. They want their son to be as successful as they are, so they enter him in every piano competition held. They are very unhappy when he does not win. “When I was your age, I used to win every competition I entered,” Winston’s father tells him. Winston is always afraid that he will disappoint(使…失望) his parents and now he always seems quiet and unhappy.
