Question

D    Junk is everywhere，even in space．Space junk travels at eight kilometers a second，according to an article in the Guardian．Catching it may be a little difficult．
    Luckily，scientists at the Swiss Space Center have a new cleaning plan．They are about to send a"cleaner satellite"into space．It will clean up space junk．Named ^uClean Space One''，the Swiss satellite finds its tareet and moves close to it When it reaches its target，it will catch the junk with a gripping claw（抓手）．This is not going to be an easy task because both the satellite and the junk are traveling so fast．
    Once Clean Space One has caught the junk，all it has to do to get rid of it is to fly back to the Earth．This is because the junk will bum up when traveling through the atmosphere （大气层）．The satellite itself，too，will bum up at the same time．
    So far，NASA has found 16，000pieces of junk that are larger than 10cm in diameter and more than 500，000pieces measuring between 1cm and 10cm．You can imagine how many even smaller ones there are in space．
    Space junk is dangerous for spacecraft and the International Space Station．Even a very small piece of junk could seriously destroy a satellite or spacecraft if they collide （碰撞）．The International Space Station has to regularly change its orbit（轨道） to avoid space junk．
61．According to the article，space junk___．
A．travels very slowly and safely in space
B．travels at the same speed as satellites
C．will cause a lot of trouble to space stations
D．will be easy to catch by the"cleaner satellite"
62．What does the underlined word"targef"refer to？___
A．Space junk    B．Cleaner satellite    C．Space craft      D．Space station
63．After the space junk is caught，it will___．
A．be carried back to the earth
C．change its orbit
B．disappear at once
D．bum up in the atmosphere
64．According to the passage，which of the following is TRUE？___
A．Space junk is harmless to people on Earth．
B．Catching space junk is not an easy task．
C．lean Space Onegoes back after finishing its task．
D．The International Space Station can't avoid space junk．
65．What does the passage mainly talk about？___
A．What kind of junk remains in space．
B．Why Space Station avoids junk．
C．When scientists invented"Clean Space One"．
D．How scientists clean harmful space junk．

Answer 1

答案：61．C  细节理解题．根据第一段句子Space junk travels at eight kilometers a second，according to an article in the Guardian．Catching it may be a little difficult．《卫报》的一篇文章称，太空垃圾的飞行速度为每秒钟八公里．捕捉它可能有点困难．和第二段句子When it reaches its target，it will catch the junk with a gripping claw（抓手）．This is not going to be an easy task．当它达到目标时，它会有夹爪抓住垃圾，这并不是一个容易的任务，可知太空垃圾会给空间站带来很多麻烦．故选C．
62．A  细节推理题．根据上文It will clean up space junk．Named ^uClean Space One''，the Swiss satellite finds its tareet and moves close to it When it reaches its target．它将清理太空垃圾，名叫^uClean Space One''，瑞士卫星发现目标移动接近它，当它达到其目标时．可知targef指的是上文提到的太空垃圾．故选A．
63．D  细节理解题．根据第二段句子This is because the junk will bum up when traveling through the atmosphere （大气层）．The satellite itself，too，will bum up at the same time．可知它将在大气中燃烧．故选D．
64．B  细节判断题．根据第一段第三行句子This is not going to be an easy task．这并不是一个容易的任务．可知这并不是一个容易的任务．故选B．
65．D  主旨归纳题．根据整篇文章内容及其第一段第二行句子Luckily，scientists at the Swiss Space Center have a new cleaning plan．They are about to send a"cleaner satellite"into space．It will clean up space junk．幸运的是，在瑞士空间中心的科学家有一个新的清洁计划．他们将发送一个"清洁"卫星送入太空．它将清理太空垃圾．可知科学家如何清理太空垃圾．故选D．
