“你是一个缺乏自信的人。老师讲课你明明知道答案却不敢举手；来了客人不敢同客人说话；有人批评了你，脸就红到了耳根，你也不会去想一想这批评是对还是错……有一次期末考试，该考数学了，你看到你平常数学成绩不好，就很害怕。结果，缺乏自信的心理使你本不该错的、不会错 “You are a person who lacks self-confidence. The teacher did not dare to raise his hand when you taught the lesson; you did not dare to speak to the guests; someone criticized you and the face was red, and you would not think about it.” Whether the criticism is right or wrong... There is a final exam, which is mathematics, and when you see that your usual mathematics score is not good, you are afraid.As a result, the lack of self-confidence makes you wrong or wrong.
