假若你是《21th century》报纸的编辑，有一学生向你写了如下的一封信，请你根据来信的内容写一封回信，帮他出出主意。字数约为100左右。
Dear Editor,
My physics teacher is very strict with us. I often feel nervous in his classes because we are punished by being made to stand for a few minutes if we can't answer his questions. It's embarrassing (尴尬) to be made to stand in class, so I hate physics classes. However, I really want to do well in physics. What should I do?
