Happy teachers’ Day! I’m studying in a primary school in Washington(华盛顿). I’m not good at English. My friend Jim is from England. He often helps me with my English.And I teach him Chinese.
The students in my class are very interesting.Bill is English.David is Australian. He’s from Sydney. Nancy is American.She’s from New York. My teacher,Mrs Smith is Canadian. She’s from Ottawa(渥太华).
My good friends,Zhang Ling and Wu Qing are Chinese,too.They’re from Taiwan.We’re from many different countries,but we are friends.

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
