江西省重点中学2023届高三下学期第一次联考英语试卷 学校：_____姓名：_____班级：_____考号：_____ 一、阅读理解 Finding perfect places for launching The Shenzhou XIV crew members began their six-month mission on June 5. When the crews mission finishes around the end of 2022, the Tiangong space station will be fully operational, according to China Daily. Developments have been made not only in space, but also on Earth. There are currently six satellite launch sites in China, including Jiuquan Satellite Launch Center in Gansu, Xichang Satellite Launch Center in Sichuan, Taiyuan Satellite Launch Center in Shanxi and Wenchang Spacecraft Launch Site in Hainan; and two newly constructed ones: China Oriental Spaceport in Shandong and Xiangshan Satellite Launch Center in Zhejiang. How are the launch sites chosen Several factors are taken into consideration. Site location Launching a spacecraft should consider the Earth’s rotation（自转）. The lower the latitude（纬度）, the faster the Earth’s rotation. If the satellite’s orbit is in the same direction as the Earth’s rotation, a lower latitude adds to the speed when the satellite is launched, leading to lower fuel costs. Experts claim that if a satellite is launched at the equator, where the Earth’s rotation is the fastest, the fuel usage can be reduced by 5 percent. Weather conditions Imagine launching a rocket on a stormy day doesn’t seem possible, does it The sites require a stable climate with low temperature fluctuations（波动）. If the local climate varies dramatically, it is more difficult for scientists to monitor the spacecraft and perform experiments. A stable climate could also reduce variations of experiments since the weather has little effect on the tests. For example. Jiuquan Satellite Launch Center has perfect weather conditions. Being dry and warm, the site is suitable for launches nearly 300 days a year. Transportation factors An ideal launch site should be located in a large space with a small population. But the launch site cannot be located in the middle of nowhere. Launch activities require a big amount of material. Therefore, the site needs to be close enough to transportation infrastructure, such as ports, rails and roads. Wenchang Spacecraft Launch Site was constructed near coastal ports which allows access to transportation. 1、According to the text, where is the most fuel-efficient place for launching satellites A. Xiangshan Satellite Launch Center. B.Wenchang Satellite Launch Site. C.Xichang Satellite Launch Center. D. Taiyuan Satellite Launch Center. 2、What makes the Jiuquan Satellite Launch Center an ideal place for launching satellites A. It lies at a relatively low latitude. B. It is wet and warm throughout the year. C. There are clear temperature fluctuations day and night. D. The local climate is nearly steady all year round. 3、Why was Wenchang chosen as a Spacecraft Launch Site A. It enjoys access to marine transportation. B. It is near many research centers. C. It ca ... ...
