My suggestion would be to do a calming activity, such as drinking tea, taking a deep breath, listening to some light music or meditating (冥想), before you perform.However, I have to wonder if performing is the only way for you to become more popular. Perhaps you can do something else to impress (使……印象深刻) your classmates. Everyone is good at something.But finally, I also wonder if you really need to be more popular in the first place. Do you have at least a few close friends? Are your studies going well? Are you healthy? If so, maybe you don’t need to care so much about being popular. Not everyone is going to like you all the time. But as long as you have a few close friends and a family to support you, you won’t need all those other people.Mike 38.Why does Miracle feel worried?A.She cannot get on well with others.B.She is too popular at school.C.She has trouble talking onstage.D.She has difficulty with her schoolwork. 39.What does the underlined word “destroy” in the first letter?A.偷窃B.顶替C.忽略D.摧毁40.What advice does Mike give to Miracle?A.She can listen to some rock music to cheer herself up before performing.B.She doesn’t need to be popular if she has some close friends and a family to support her.
