    Today is Sunday, April 15th, everyone in Sheep Village（羊村）is very busy. What does he/she do?

    I'm Nuan Yangyang. I write a letter to my friend at one o'clock in the afternoon. Then I do my homework.

    I'm Fei Yangyang. I want to be strong（强壮的），so I go to the sports club to play sports in the morning. I go home at three ten in the afternoon.

    I'm Lan Yangyang. I like eating. I have breakfast at home. I have lunch in a restaurant. But the food isn't good, I don't like it.

    I'm Mei Yangyang. I go to a clothes store at nine in the morning. The clothes there are on sale, so I buy a nice skirt.

    I'm Xi Yangyang. I take the bus to the English club at ten sixteen in the morning. There I help two kids learn to speak English.
