听力原文: Some people are right-handed and some are left-handed. No one knows the reason w
One day I tried an experiment: changing hands while eating rice with chopsticks. Being a right-hander, I hoped it would not be too hard for me to take the food with my left hand. Soon after I started, I realized I didn't know what I was doing. So I moved in front of a big mirror in order that I could observe my actions clearly. Looking at myself in the mirror, I found I looked like a man who had never used chopsticks. I became more and more nervous and finally I had to give it up.
My experience shows, being forced to use the hand one Is not used to affects a person's mind. So we should not try to change a left-hander. Some people still think being left-handed, is bad, but lucidly this idea is changing.
Whether a person is right-handed or left-handed results from ______.
A.the education of the parents
B.the education of the teachers
C.the practice of oneself
D.the example of the friends
