单项选择题
Read the passage and answer five questions.What’s your impression of a qualified teacher? Think for a moment about the teacher you have had at school. Which one did you like most? And why? Were the teachers you liked most also the ones who were the best teachers, in your opinion? Before you read any further, consider for a minute the qualities that make a teacher outstanding.Some very common answers to this question are that teachers need to love their students, that they need to have an expert knowledge of their subjects, and that they should devote themselves completely to their jobs. All of these ideas are, of course, true to a certain extent but they are perhaps a little too simple.It is impossible for anyone to love everyone he knows, and teachers deal with a very large number of students over the years. On the other hand, teachers should certainly be able to make their students feel that they are interested in them as people and in the development of both their brains and their characters. A deep knowledge is the ability to pass that knowledge on to the students effectively—a teacher needs to be trained in the skills of teaching. These skills include how to control a class, and so on. Finally, teachers have to devote a lot of time and energy to their work, of course. However, they are also models that their students must follow, so it is important that they should be well-balanced people with interests outside their schoolwork—family, friends, hobbies, etc. A teacher who only lives for work is likely to become too narrow-minded.The author suggests that ______. （ ） A. teachers should spend all their time teaching B. teachers should be people both working and living well C. teachers don't need to be trained for teaching D. we could only learn from outstanding teachers
