    Most Chinese students tend to be silent and reluctant to answer questions in class， let alone to raise any question. It is in fact a very bad custom for a student. We should be active in class.
    First of all， students should show initiative. During a class， only listening to the teacher and taking notes are not enough. We must use our heads and think along with the teacher. By answering questions， we can test our knowledge. By raising questions to the teacher， we may learn more. In addition， being active in class will strengthen our confidence. If one is too timid to answer a question in class， how can he get enough courage to take any challenge in society in the future？
    No opportunity waits for men， but men can grasp opportunity. The same is true of the studies in class. We will find more opportunities in class if we are active enough， and we will certainly learn more than those passive ones.
