It’s Sunday today. It’s cold. I put on my warm clothes and go to visit my uncle. My uncle is a farmer. He has a small farm. There are many apples on the farm. I like to eat them. There are five cows on the farm too. I can milk the cow. It’s fun. I always have a good time on the farm. Sometimes I go to the farm with my father and mother. But they can’t go to the farm today. Because they have to go to work today. What a pity!

3．What does the writer’s uncle do?
4．What’s on the farm?
5．Why can’t the writer’s parents go to the farm today?

y = sin x， x∈R， y∈[–1，1]，周期为2π，函数图像以 x = (π/2) + kπ 为对称轴
y = arcsin x， x∈[–1，1]， y∈[–π/2，π/2]
sin x = 0 ←→ arcsin x = 0
sin x = 1/2 ←→ arcsin x = π/6
sin x = √2/2 ←→ arcsin x = π/4
sin x = 1 ←→ arcsin x = π/2
