【答案解析】[听力原文]
Some people are right-handed and some are left-handed. No one knows the reason why a person becomes right-handed or left-handed. {{U}}It is not true that it is caused by the way in which his parents educate him. In other words, a person is born to be right-handed or left-handed{{/U}}. Moreover, the left-handed and the right-handed "think" differently. Having to use the hand you're not used to can be very upsetting.
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. {{U}}So I moved in front of a big mirror, in order that I could observe my actions clearly{{/U}}. {{U}}Looking at myself in the mirror, I found I looked like a man who had never used chopsticks{{/U}}. I grew 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 to a right-hander. Some people still think being left-handed is bad, but luckily this idea is changing.
[解析] 细节题。短文开头说到没人知道为什么有左撇子和右撇子之分，有人说是由父母的教育方式造成的，这是个错误的观点。换句话说，人一生下来就已经决定是左撇子还是右撇子了，即决定人是左撇子还是右撇子的是自身的基因，C为正确答案。
