Problem: Given the question: W: Hello. Is that Mr. Jackson? M: Yes, it is. W: Mr. Jackson. I am a reporter from the TV station at our school. As far as I know, you are a very successful teacher, and quite popular among the students, so I want to ask you some questions about your teaching and your students. M: OK. W: First question, do you often give homework to your students after class? M: It depends. Maybe once or twice a week. W: Do you think it is good for your students to do a lot of homework? M: No, I don't think so. Too much homework takes too much of their free time. I seldom give homework to my students on the weekend. W: Do you agree the students need a lot of exercises in their spare time? M: Well, yes, but they also need time to relax and have a rest, especially on weekends. W: You are a great teacher. By the way, what do you do in your free time? M: I'm a very good football player. My team won the first place in our city last year. W: Congratulations! Well, thank you for your help.

input question: W: Very simple. Take digital photos of youth culture and send them to my company. It's called Look-Look. M: What kind of company is it? W: It's a youth culture marketing and trend forecasting firm in Hollywood. I'm one of Look-Look's 65,000 trendspotters worldwide. M: Look-Look gets a lot of information about the ever-shifting tastes of the youth market by these images. W: Yes, its clients are mostly companies. They get information about trends from Look-Look and develop their products. They also use the images of Look-Look on their websites to impress young people and promote their newly designed products. M: But are there any people who don't like their pictures to be used on the website? W: I always have my subjects' permission before I take their pictures and put up their images onto Look-Look.com. M: Where do you find your best subjects? W: At school, in the park, at local supermarkets and near many music clubs. M: What is difficult about this job? W: To catch our original styles because so many young people try hard to stand out. You have to be able to find the difference between someone who is copying trends and someone who is truly inventing a new look. M: Thank you for talk with us, Emily.
