Now the children can read books for free in some villages in Indonesia. A moving library lends books to them in exchange for the waste. 1. They only need to collect waste. The special library was founded by Raden. 2.她经常给孩子们准备许多书。Each weekend, she uses the books to exchange for plastic bags, cups, bottles and other waste. 3. As soon as she arrives, the children will carry their waste to ask for books. Raden collects about 100kg waste each week and then sorts it out. Then she sends it for recycling or sells it. 4. Now the children are spending less time on online games but more time in reading. It’s a good way to help children develop their reading habits. It can also help them learn to care for the environment. Kevin is a 15-year-old reader and he always spends time looking for waste in his village. “When there is too much waste, our environment will become dirty. 5.这对我们的健康不好。That’s one of the reasons why I pick up waste in order to borrow books.” he said.

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
