3Dprinters have been around us for some time. There is a lot you can do and image with a 3D printer. ____（小题1）____
A company in China has recently used 3D printers to make ten full-sized housed in just 24 hours. ____（小题2）____. These houses are printed with special “ink ”that has been made from industrial construction waste. The using of cheap materials makes it possible to print each house under ＄500（小题3）The CEO of the company says , “____（小题4）____ ”He plans to set up 100 recycling factories across China and changing waste into cost-effective “ink ”for 3D printers. ____（小题5）____However ,at present ,multi-storeys 3D-printed building are not allowed in China. So,it’s important that the 3D printing technology will be widely used to build any time soon. Maybe there be still a long way to go.
（小题6）According to the passage ,which of the following is TURE?
| A．Each of the printed housed costs at least 5000dollars . |
| B．There’s no limit in China to print tall building with 3Dprinters . |
| C．The 10full-sized houses are printed out of recycled materials. |
| D．3D printers will soon caome into commom use to build houses . |

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
