You are standing with your classmates.       is talking except you. Perhaps you are   they will laugh at what you say. Maybe you just aren’t brave enough to speak.
Shyness is like a snake that crawls (爬) into our mouth and stops us        . But we shouldn’t let it stay there.
I am 29 years old. Even today, that snake still sometimes        me. When I was in high school, I was so shy that I wouldn’t talk to anyone except my parents and best friends. If a stranger asked me the       to a local shop, it was as if I’d forgotten how to talk. One summer, I       a job in a restaurant and that helped a lot. It meant I had to talk to customers. I had to tell them how much their meal cost. I had to ask them         they wanted to drink Coke or Sprite (雪碧). This job taught me how to speak with people.
You may be too young to find a part-time job. But you can look for other       to speak with people. You can offer to help an old woman        her heavy bag. Or you can go to get a newspaper for your family. If you do these things for a while, the “shyness”  snake     you alone. It’ ll look for another mouth to crawl into.
