What is recycling? It is to reuse everything that can be used again. Recycling is good to our Earth. Recycling also means doing everything we can do to prevent(阻止)the need for recycling. How do we do this? Here are some suggestions(建议)：
1. If you bring your own bags with you to the shops, you won't need to use the bags of the shops. This will save bags before they need to be recycled.
2. Don't buy things that can be used only once. For example, you should use glass cups instead of(代替)paper cups.
3. Dress warmly in the cold season(季节) and use less heat. Dress in cool clothes during the warm season and reduce(减少)the use of air conditioners(空调).
4. Don't leave the fridge door open for a long time!

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
