What is recycling? It is to reuse anything that can be used again. Recycling may save our world. “ 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:
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). For example, use cloth napkins (餐巾) instead of (代替)paper napkins.
Put on warm clothes in the cold season, dress in cool clothes during the warm seasons and avoid（避免）using air conditions (空调).
Don’t leave the fridge door open for a long time!
Turn things off after you use them.
Take showers instead of baths. If you take showers, you use much less (较少的) water.[[QOrDeR]]“ ” is to reuse something that can be used 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
