Unit 4 Space Exploration课时素养检测十四Unit 4Period 2. 阅读理解AChinas first astronaut 38-year-old Yang Liwei returned safely to earth Thursday morning, when his craft Shenzhou 5 touched down as scheduled after more than 21 hours in the earths orbit. Chinese premier Wen Jiabao called the landmark debut flight a “complete success”. The descent capsule(返回舱) carrying Lt. Col. Yang Liwei touched down on the grasslands of the Gobi Desert, in central Inner Mongolia at 6: 23 am Thursday (Beijing Time), the Beijing-based Chinas Aerospace Command and Control Centre said. Minutes later, Yang grabbed the capsule hatch with his hand, pulled himself out, smiled and waved at recovery teams and reporters. “It is a splendid moment in the history of my motherland and also the greatest day of my life, ” Yang, a former fighter pilot from Northeast Chinas Liaoning Province, said immediately after emerging. In an interview with CCTV, Chinas state television, Yang said he was “feeling excellent”. Shenzhou 5 landed at dawn, 4. 8 kilometres (3 miles) from its designed landing target, the officials said. “The spaceship operated well, ” the astronaut Yang Liwei said in his first publicized comments. “I feel very good and I am proud of my motherland. ” After a physical exam on the spot, Yangs condition was found as “good”. Li Jinai, the commander of Chinas manned space program, called Yang a “space hero” and a “national hero”. Following Yangs touchdown, Chinas premier Wen Jiabao immediately spoke to Yang from Beijings command and control centre and offered his congratulations. Within hours, Chinese space officials announced that the countrys space dreams will continue with a “Shenzhou 6” mission, most possibly within a year. They said China also had worked out plans to conduct space walking by its astronauts, and eventually would build up a space station. However, Chinese scientists ruled out building a space shuttle, like the United States. Yangs flight came four decades after the former Soviet Union and the United States pioneered manned spaceflight. Soviet cosmonaut Yuri Gagarin orbited the Earth in April 1961. One month later, the United States launched Alan B. Shepard Jr. 【语篇概述】本文介绍了中国首次载人航天飞行的情况。1. What is true of the first Chinese astronaut Yang Liwei? A. He is now a fighter pilot. B. He was helped to get out of the descent capsule. C. He spent nearly a day in space. D. He was called a “space hero” and a “national hero” by Chinas premier Wen Jiabao. 【解析】选C。细节理解题。根据第一段中的after more than 21 hours in the earths orbit可知, C项正确。2. China will carry out the following space programs in the near future except _. A. space walkingB. setting up a space stationC. building up a space shuttleD. sending up “Shenzhou 6”【解析】选C。细节理解题。根据第二段中的Chinese scientists ruled out building a space shuttle可以知道, 中国在近期不打算建航天飞机。其中的 ruled out 意为“排除, 取消”。3. The underlined word “debut” means _. A. first public appearanceB. spaceC. carrying personD. spaceship【解析】选A。词义猜测题。从短文中我们知道, 这是中国第一次载人航天飞行, 由此可推测出, debut为“首次亮相” 之意。4. Which of the following is NOT true? A. Soviet cosmonaut Yuri Gagarin was the first man in the world to travel in space. B. the United States launched Alan B. Shepard Jr. in 1961. C. China is the third country in the world to carry out the manned space flight successfully. D. “Shenzhou 6” will carry more than one astronaut in the mission. 【解析】选D。推理判断题。选项A、B、C在短文中均有提及。D没有提到。BAn exciting landing process of Change-4 lunar probe (月球探测器) was seen through the monitor at Beijing Aerospace Control Centre in Beijing, Jan. 3, 2019. It touched down on the far side of the moon at 10: 26 a. m. Beijing Time, becoming the first spacecraft soft-landing on the moons unknown side never visible from Earth. Chinas Change-4 probe has started the exploration on the far side of the moon thanks to the relay satellite that provides a communication link with ground control. The relay satellite, named Queqiao, meaning Magpie Bridge, after a Chinese legend (传说 ) , was launched on May 21, 2018, and became the first communication satellite operating in the halo orbit, nearly 500, 000 km from the earth. It can also provide communication for probes from other countries. The relay satellite will also be used for scientific and technological experiments. The maximum distance between the satellite and the Change-4 probe on the far side of the moon is 79, 000 km. The satellite processes data from the probe and sends it to Earth. The satellite can stay in its orbit for a long time due to its relatively low fuel consumption, as the earths and moons gravity balances its orbital moving. While in orbit, it can “see” both the earth and the far side of the moon. The concept of using a relay satellite in the halo orbit was first put forward by U. S. space experts in the 1960s, but was realized by Chinese space engineers. Researchers hope to u
