China’s first moon rover，Yutu，or Jade Rabbit，separated from the lander early on Sunday，Dec

China’s first moon rover，Yutu，or Jade Rabbit，separated from the lander early on Sunday，December l5，2013，several hours after the Chang’e-3 probe (探测器) soft-landed on the lunar surface．The l 40 kg six-wheeled rover touched the lunar surface at 4：35 a．m．，leaving deep trace on the loose lunar soil. The process was recorded by the camera on the lander and the images were sent to the earth，according to the Beijing Aerospace Control Center．
After the separation，the rover and lander will take photos of each other and start their own scientific explorations. Engineers made final checks of the environment of the landing site，the situation of the probe and sent signals of separation to Chang’e-3．
Yutu, on the top of the probe，extended its solar panel and started to drive slowly to the transfer mechanism (机械装置) at 3：10．The transfer mechanism unlocked at 4：06 with one side reaching the moon’s surface，allowing the rover to descend to the surface following a ladder mechanism．
Chang’e-3 landed on the moon’s Sinus Iridum，or the Bay of Rainbows，at 9：11 p．m．Saturday，making China the third country in the world to carry out such a rover mission after the United States and former Soviet Union．
In ancient Chinese mythology，Yutu was the white pet rabbit of the lunar goddess Chang’e．The name for the rover was selected following an online poll that collected several million votes from people around the world．
The rover，1.5 meters long with its two wings folded，1 m in width and l．1 m in height，is a highly efficient robot controlled by the command center from the earth．It will face challenges including temperature differences of more than 300 degrees Celsius on the moon．
Yutu will survey the moon’s geological structure and surface substances and look for natural resources for three months，while the lander will conduct in-situ (现场) exploration right at its landing site for one year．
【小题1】What’s the passage mainly about?A．China’s first moon rover，Yutu，touched the lunar surface．B．The rover and the lander took photos of each other successfully．C．Chang’e-3 landed on the moon’s Sinus Iridum, or the Bay of Rainbows．D．Yutu will survey the moon’s geological structure to find substances．【小题2】Which of the following show the correct order of the Yutu’s landing?
a．drive to the transfer mechanism b．extend its solar panel c．follow a ladder mechanism
d．descend to the surface e．unlock the transfer mechanism A．e→b→a→c→dB．a→b→e→d→cC．b→a→e→c→d D．c→a→b→e→d【小题3】We can learn from the last two paragraphs that ．A．Yutu’s two wings are l．5 meters long and l meter wideB．Yutu will explore the moon right at its site for one yearC．Yutu will get out of the earth command center’s controlD．Yutu can bear great temperature differences on the moonA

(答案→)A 解析： 玉兔登上了月球！2013年11月15号，在嫦娥3号飞船登陆月球表面数小时后，玉兔在凌晨4：35分登陆月球。【小题1】主旨大意题。本文是一篇新闻报道，介绍了我国第一座月球车登陆月球的事件。故选A。【小题2】细节理解题。由第三段可知“玉兔”的活动顺序。展开其太阳能电池板 → 驶向机械装置 → 打开机械装置→ 跟踪一个梯形机械装置 → 降落到表面。 故选C。【小题3】推理判断题。由“It will face challenges including temperature differences of more than 300 degrees Celsius on the moon．”可知玉兔可以适应月球表面暂时的温度变化。 故选D。
