THEME-RELATED WRITING Choose one of the following writing tasks and complete it after class. 1) Based on Text A and what you’ve discussed in “Voicing Your Views”, write a short essay (of about 150 words) entitled “A Creative Person” in accordance with the following outline: a. A creative person I know b. The traits that can be found in him / her ? Sample Essay: My physics professor is a very creative person. His research project for his doctoral dissertation dealt with a very complicated physics problem at a time when many others thought it was impossible to solve it. But he creatively introduced a new concept and finally resolved the theoretical and experimental contradiction. He possesses many unique traits. He is very energetic and hard-working. He chairs the Physics Department and teaches many hours a week. Meanwhile, he is in charge of the university’s technology research. Obviously he is a quick efficient worker. My professor can be eccentric, once he shocked the whole class by saying “Good physics, everyone” instead of “Good morning, everyone”. But above all, my professor has a sincere interest and a strong passion in his research field. No wonder he is highly respected by both his colleagues and his students. 2) Some sayings in our life sound so familiar and natural to us that we take them for granted without a second thought. Do you realize that when you take them as “absolute truths”, you are locking your mind and creativity? Write a brief comment on such a saying in about 150 words. ? Sample Essay: Popular Sayings May Become “Mental Locks” To cultivate a creative mind, one needs to chip away at one’s “mental locks”. Some of the “mental locks” are shaped by popular sayings, which sound so familiar to us that we tend to take them for granted. Instructive as they may be, these common statements may restrict our freedom to think. “Look before you leap!” We make this remark to caution someone to think carefully before making a decision or taking an action. It may seem sound advice, but it may also put him or her in a passive position. He or she may just keep “looking” round and without making a “leap”. Similarly, we may say to the same person, “Don’t let the chance slip through your fingers!” Then, the person may be motivated to act promptly, regardless of the consequences. In either case, the personal may fall victim to popular sayings. So, if we want to come up with a new idea, we must break up the “mental locks” that close our minds.
