判断正误。
It is Sunday today. The weather is fine. Bob and Jane are in the park. It is a big park. They can see many people there. They come here to have a rest after a week's hard work and study. Some boys are playing chess on the grass. Some girls are singing and dancing. An old woman is reading a newspaper under a tall tree. A young man and his little son are playing with a toy car.
How happy they are!
