We can't stop an earthquake(地震), but we can do things to make sure they don't destroy(毁坏) whole cities. First, it is not a1. idea to build houses along lines where 2. of the earth's plates(板块) join together. Second, if you think there 3. be an earthquake, it is better to build houses on rocks , not on 4.. Third, you must make the houses as 5. as possible. Weak buildings will fall down in an earthquake, but strong ones may6.Scientists are 7. that one day an even bigger earthquake will hit the part around San Francisco(旧金山) . They call it " The Big One ". However, people today are still building more 8. . The population in and around San Francisco is. 9. ten times more than it was in 1906. This means that10. there is another earthquake, a great many houses and buildings will be destroyed.

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
