What is recycling? It is to reuse anything that can be used again. Recycling may save our world. How do we do this? Here are some suggestions:
If you bring your own bags with you to the shop, you won’t need to use the bags of the shop. This will save bags before they need to be recycled.
Don’t buy things that can be used only once(一次). Don’t use too much paper napkin(餐巾). You can use cloth(布) napkins.
Put on warm clothes in the cold seasons, dress in cool clothes in the warm seasons. So you can’t use air conditions(空调) too much.
Don’t leave the fridge door open for a long time! Turn off the tap (水龙头)after we wash our hands.

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
