The reading passage describes two kinds of motivation: extrinsic motivation and intrinsic motivation. The former comes form a reward outside the individual, while the latter is the result of being willing to do something intrinsically. The case where one is intrinsically motivated at the beginning but lose such motivation because some extrinsic rewards are given to him is called overjustification. In the listening passage, the professor tells a story of Marnie, a girl who used to enjoy singing as a child. She enjoyed singing so much that she sang at school, community events and in front of family members. In this period of time, she sang out of intrinsic motivation. However, when Marnie grew up, she did not like singing like she did as a child because everyone expected her to sing. Even though she still earned applauses after each performance, she just lost the passion to sing. One day a man came to Marnie and asked if she was willing to sing professionally, which meant that she would sign a contract which would give her great financial support. Knowing that she was not interested in singing at all, though, Marnie signed the contract still. In this case, while she sang because of the intrinsic motivation as a child, the outer reward, financial support here, replaced the intrinsic motivation and became the only motivation for her to sing. Such a process is called overjustification, as mentioned in the reading passage. 要拜托大家给我意见了，是否可以从我的文章中，知道reading以及listening的内容？ 以及请提供我更好的写法，谢谢！ --
