The BINGO Kids are 1． a field trip in the forest. They are 2． up trash. There are 3． bottles and tin cans in the forest. In some areas, there aren’t many 4．. So the kids are 5． new trees. In the year 2050, these trees will be 6．.
During the break, the kids talk about life in the 7．. Some kids say the 8． will do many things, such as shopping and 9． dishes, but computers can’t 10． trees. Everyone will 11． in modern cities, but some people still love the 12．.

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
