That was a hot summer. When I was five years old just before my sister came to the world, my mother asked me what we     (应该)name the new baby. I think for a minute and said, “Let’s call her Gravy!”
You know, we pour gravy over meat and it tastes good! My parents found my idea  
(有趣的)but at last they named the new baby Caroline,   （代替）.
Having a sister    (改变) my life. When my sister and I played together, we often fought and    （争吵）with each other. It made our parents angry. But at the same time, we learned to    （分享） our things and forgive（原谅） each other.
In North America, there are many    （种类） of families but most families have a boy and a girl. Of course, some have three or more. In China, most    （孩子）don’t have brothers or sisters and they often feel    （孤独的）. Some middle school students in China wish that they had a brother or sister. If you are one of them, I have a good idea for you. You can treat your friends or classmates   （当作） your brothers and sisters!
