It snowed last night. In the morning everything was white.
I got up early and went out to clean the snow. A lot of bikes were coming and going. Suddenly（突然地）I saw a woman fall off her bike. She lay（躺）on the ground and couldn’t get up. I ran up to her and tried to help her get up. She sat up but still couldn’t stand up. Because her right leg was broken. Then Dongdong’s father, a policeman, came over. When he saw that, he called a taxi. The taxi driver sent the woman to the hospital. I went to the hospital with her. There I phoned the woman’s family. Then I said goodbye to her. The woman thanked me again and again.

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
