单词拼写（每小题1分，共10分） 小题1: Life in the oceans

You’re standing with your classmates. Everyone is talking e 小题1:  you. Perhaps you’re afraid they will laugh at you when you say. Maybe you just aren’t brave e 小题2:   to speak. Shyness is like a snake that crawls（爬进）into our mouth and p 小题3: us from speaking. But we shouldn’t let it stay there.

I am 29 years old. Even today, that snake s 小题4:  sometimes visits 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 w 小题5: to a local shop, it was as if I’d forgotten how to talk. One summer, I got a job in a restaurant and that helped a lot. It meant I had to talk to customers（顾客）. I had to tell them how m 小题6:  their meal cost. I had to ask them if they want to drink Coke or Sprite. This job taught me h 小题7:  to speak with people.

You may be t 小题8:  young to find a part-time job. But you can look for other chances to speak with people. You can offer to help an old woman c小题9: 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 will soon begin to l小题10: . It’ll look for another mouth to crawl into.
