Have you ever heard the saying "If you want a friend, be one"? If you want to make friends with others, you should be friendly to them first.

Here is how one new teacher made friends with the students in her class on the first day of school. As the bell rang, the teacher smiled (微笑) at each student. Then she said in a quiet voice,"Good morning. How nice it is to have all of you in my class this year. I'd like to know each of you. I am sure we will enjoy working together." Her voice was sweet(甜美的) and her look was friendly, so everyone felt happy.

She told the students her name and wrote it on the blackboard. Then she told them some of the things she liked to do and she hoped to do with them during the year. Then she said to the boys and girls, "Now you know my name and the things I like and I want to know your names and the things you like."

Could you make friends by doing the same as this teacher did?

One way of getting to know girls and boys in your class is to find out more about them. People often make friends with those who are the same as them. You play the same games and go on vacations together. It is a good way to make friends.
