    When the teacher asks a question in class, Wang Xiaobin never raises his hand and this situation is very common at middle schools. This 15-year-old boy always waits for other classmates or the teacher to give the answer. “What if my answer is wrong?” Wang asks.

    Wang said only six or seven students in his class raise their hands when a question is asked. ①“I think it's a problem that may affect (影响) our studies, but I am afraid of making mistakes in front of my classmates,” he said.
