一说起科代表，我的脑海里就不由自主地浮现出一群其貌不扬却令我惊叹不已的人物。在我的眼中，这些科代表除了称职以外还是称职，他们是该课老师的左右手、代言人。出于他们口中的消息宁可信其有，不可信其无。他们说今天的作业是这些就是这些；他们说下星期测验，下星期就准 As soon as I talked about the representative of the branch, my mind couldn’t help but emerge a group of people who couldn’t help but amaze me. In my eyes, the representatives of these departments are qualified in addition to their qualifications. They are the right-handers and spokespersons of the teacher in the class. Because of the news in their mouth, they would rather be trusted for their credibility. They said that today’s homework is that these are these; they say that next week’s quiz will be correct next week.
