Translation. Translate the following passage into Chinese. When women work for women, a different dynamic often takes over. Susan, a cashier in a Toronto auction house, says that she has explored friendships with some of her female bosses and feels she can rely on them more. While women may feel more at ease with a female boss, men often have to make concessions to the new working styles. Brian, a marine biologist, says, “It took me a couple of years before I felt comfortable enough to relax around a female manager. In fact, my relations with her were much more businesslike.”

Translation. Translate the following passage into Chinese. Studying the humanities improves our ability to read and write. No matter what we do in life, we will have a huge advantage if we can read complex ideas and understand their meaning. We will have a bright career if we are the person in the office who can write a clear and elegant analysis of those ideas! Studying the humanities makes us familiar with the language of emotion and the creative process. In an information economy, many people have the ability to produce a useful product such as a new MP3 player. Yet, very few people have the ability to create a spectacular brand: the iPod. Most importantly, studying the humanities invests us with great insight and self-awareness, thereby releasing our creative energy and talent in a positive and constructive manner.
