阅读理解 Chinese astronauts sent back a science lesson from the country's under construction space station. The lesson focused on physics, aiming to illustrate how the weightless environment affects buoyancy, the movement of objects and optics (光学). Students from five cities asked the astronauts about living conditions in space and were treated to a virtual tour of the station. Wang Yaping, the only woman aboard the station, served as the main instructor, while Ye Guangfu assisted and commander-in-chief Zhai Zhigang worked the camera. The three arrived at the station in October, 2021 for about a six-month stay, mainly aimed to prepare the main Tianhe module(舱) for the arrival of two additional modules named Mengtian and Wentian ahead of completion by the end of 2022. The crew is appraising living conditions in the Tianhe module and conducting experiments in space medicine and other areas. Wang became the first Chinese woman to conduct a spacewalk when she and Zhai spent six hours outside the module fixing equipment and carrying out tests alongside the station's robotic service arm. The mission of Shenzhou-13 is China's longest one since it first put a human in space in 2003, becoming only the third county to do so after Russia and the US. China has also pushed ahead with unmanned missions, and is lunar exploration program generated media buzz when its Yutu 2 rover sent back pictures of what was described by some as a "mystery hut", but most likely only was a rock of some sort. The rover is the first to be placed on the little-explored far side of the moon, while China's Chang'e 5 probe returned lunar rocks to Earth for the first time since the 1970s. A Chinese rover, meanwhile, is searching for evidence of life on Mars. （1） What is the main task of the three crew in China's space station? A . To give lessons about physical principles. B . To prepare for the station's expansion. C . To test the station's robotic service arm. D . To do a spacewalk outside the module. （2） Which of the following can best replace the underlined word "appraising" in Paragraph 3? A . judging B . updating C . adjusting D . repairing （3） What can be implied in the last paragraph? A . China has found some strange huts on the moon. B . China has found evidence of life on Mars. C . China is preparing to find a living place on Mars. D . China has made great achievements in space exploration. （4） What might be the best title for the text? A . Chinese astronauts test new technology to explore space B . Chinese female astronauts prepares for walking outside in space C . Chinese astronauts give a science lesson from the space station D . Chinese astronauts expand the module into a big station 答案： B A D C
