Now the Earth is in bad condition. For example, in some places, the air and the water is so dirty that too many animals and plants are dead. At the same time, many animals and plants are in danger because of the destruction of their habitats.
Luckily, people have realized the problem. On April 22nd, millions of people all over the world do something good for the Earth. Some clean up lakes and rivers, some pick up rubbish, others give speeches to call on more people to take action and not to destroy (破坏) the Earth. But can we save the Earth only by one day’s work? The future of our planet depends on our efforts.
What we should do is make every day “Earth Day”. Only by taking good care of it every day can we hope to live in harmony (和谐) with nature.

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
