[2021·德州模拟]China's Mars rover, Tianwen1, will likely attempt to land at a site in northeastern Mars, according to a new paper published just days ahead of the mission's launch. The paper was written by team members of China's Tianwen1 Mars mission, which aims to send an orbiter and a rover to the Red Planet.
The study reveals new details about Tianwen1, outlining its intended landing area, science goals and the names of instruments aboard the spacecraft. It also stresses the historic nature of the mission: Not only is Tianwen1 China's first fully homegrown Mars mission, it's also the first to carry both an orbiter and a rover.
Tianwen1 means “questions to heaven” and was taken from the title of a poem by Qu Yuan (340—278 BC). The spacecraft will reach Mars in February 2021, at the same time as NASA's Perseverance rover and the United Arab Emirates' Hope orbiter launched on Sunday (July 19). However, China's rover will remain attached to the orbiter for two to three months before attempting its landing, according to the paper.
The chosen landing area is Utopia Planitia, a huge basin formed by a large impact far back in Mars' history that was also the region where NASA's Viking 2 lander touched down in 1976. China had isolated a part of the vast plain as a landing area, which means there will be more time and atmosphere for the entry spacecraft to slow down and safely land on the surface. The latitude is also suitable for receiving enough sunlight to power the 240 kilograms rover. The relatively smooth surface will also be helpful for roving. The mission also benefits from the engineering heritage of China's Chang'e lunar exploration program, the paper noted.
The Tianwen1 orbiter will operate in a polar orbit in order to map Mars. The rover will also investigate the surface soil characteristics and waterice distribution with its own Subsurface Exploration Radar. It will also analyze surface material composition and characteristics of the Martian climate and environment on the surface.
5．What's the purpose of the passage?
A．To lay out key details about Tianwen1.
B．To state how Tianwen1 was invented.
C．To stress the historic meaning of Tianwen1.
D．To analyze characteristics of the Martian climate.
6．What is most special about Tianwen1 according to Para. 2?
A．It was named after Qu Yuan, a famous poet in Chinese history.
B．It will reach Mars at the same time as NASA's Viking 2.
C．It will remain for 2 or 3 months on Mars.
D．It will complete orbiting and roving in a Mars mission.
7．Why is Utopia Planitia chosen as the landing area of Tianwen1?
A．The rare air there is suitable for the flight of Tianwen.
B．The area can protect Tianwen1 from too much sunlight.
C．It has relatively smooth surface, which is helpful for roving.
D．There is no spacecraft successfully landing there in history.
8．The last paragraph states mainly________.
A．Tianwen1's historic contributions
B．Tianwen1's new radar instruments
C．Tianwen1's academic advantages
D．Tianwen1's scientific goals
5．A 推理判断题。根据第二段中“The study reveals new details about Tianwen1, outlining its intended landing area, science goals and the names of instruments aboard the spacecraft.(这项研究揭示了天问1号的新细节，概述了它的预定着陆区域、科学目标和飞船上仪器的名称)”结合文章主要介绍了中国的火星漫游者“天问1号”可能会尝试在火星东北部的一个地点着陆，就在任务发射前几天发表的一篇新论文称。文中还揭示了天问1号的新细节，概述了它的预定着陆区域、科学目标和飞船上仪器的名称。可推知，这篇文章的目的是列出天问1号的关键细节。故选A。
6．D 推理判断题。根据第二段中“It also stresses the historic nature of the mission: Not only is Tianwen1 China's first fully homegrown Mars mission, it's also the first to carry both an orbiter and a rover.(它还强调了这次任务的历史性：天问1号不仅是中国第一个完全自主的火星任务，也是第一个同时携带轨道飞行器和探测车的任务)”可推知，天问1号最特别的地方是它将在火星任务中完成环绕和漫游。故选D。
7．C 细节理解题。根据倒数第二段中“China had isolated a part of the vast plain as a landing area, which means there will be more time and atmosphere for the entry spacecraft to slow down and safely land on the surface. The latitude is also suitable for receiving enough sunlight to power the 240 kilograms rover. The relatively smooth surface will also be helpful for roving. (中国已经将这片广阔的平原的一部分隔离出来作为着陆点，这意味着将有更多的时间和大气层让飞船减速并安全着陆在火星表面。这个纬度也适合接受足够的阳光，为240公斤重的火星车提供动力。相对光滑的表面也将有助于漫游)”可知，选择乌托邦平原作为“天问1号”的着陆点，是因为它表面比较光滑，有利于漫游。故选C。
8．D 主旨大意题。根据最后一段“The Tianwen1 orbiter will operate in a polar orbit in order to map Mars. The rover will also investigate the surface soil characteristics and waterice distribution with its own Subsurface Exploration Radar. It will also analyze surface material composition and characteristics of the Martian climate and environment on the surface.(天问1号轨道飞行器将在极轨道上运行，以绘制火星地图。探测车还将利用自己的地下探测雷达调查地表土壤特征和水冰分布。它还将分析火星表面物质的组成以及火星表面气候和环境的特征)”可知，最后一段主要阐述了“天问1号”的科学目标。故选D。
