贤知助手中考英语阅读理解：一门普通的语言

A Common Language

There is a common(1) language popular in every country in the world. All the people, old and young, men and women, must use it.

It’s everybody’s second language. It’s easy to learn, though(2) you don’t hear it. It’s sign language(3).

When you wave to a friend, you are using sign language. When you smile at someone, you mean to be friendly. When you put up your hand in class, you are saying, “Please ask me. I know the correct answer." When you put your finger in front of your mouth, you mean “Be quiet." The deaf use sign language to talk to each other. There is even a university for the deaf in the United States. There are also TV programmes for the deaf people. They use sign language to tell everybody.
