题目内容

18.She seems to prefer          American TV Shows to talking to me.(  )
A.to watchB.to be watchingC.watchingD.having watched

分析 她似乎宁愿看美国电视节目也不愿意和我说话.

解答 答案是C.本题考查动名词做宾语.题干中动词prefer后面既可以接to do也可以接doing做宾语;但是如果与介词to搭配,则往往选用doing,构成prefer doing to doing的结构,所以排除A和B;D项是动名词的完成式,强调动名词的动作在谓语动词之前,本题中没有时间上的先后关系,所以排除D,答案选择C.

点评 首先判断选项中的动词在句中是以谓语还是非谓语形式出现,然后根据选项在句中的功能结合非谓语的基本用法做出合理的判断.

9.Junk is everywhere,even in space.But getting rid of space junk is much harder than simply cleaning your bedroom.Space junk travels at 8 kilometers a second,according to an article in the Guardian.Catching it is a bit of a challenge.
     Luckily,scientists at the Swiss space center have a new cleaning plan.Theyare about to send a"cleaner satellite"into space within the next five year?.It will clean up space junk,according to a report in the Guardian.
     Named"Clean Space One",the Swiss satellite finds its target 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 Earth.This is because the junk will bum up when traveling through the atmosphere.The satellite itself will burn up a',the same time.
     Ever since people started to send objects into space more than 50 years ago,there has been junk in space.Junk on Earth like food wrappers (包装纸)or waste paper is also a problem.But space junk is mainly made up of exploded rockets and broken satellites.If no one cleans them away,they just keep traveling around Earth.
     So far,NASA has found 16.000 pieces of junk that are larger than 10cm in diameter(直径)and more than 500,000 pieces measuring between 1cm and 10cm.You can imagine how many even smaller ones there are in space.
     Space junk is dangerous for spacecraft (飞船) and the International Space Station.Even a very small piece could seriously damage-or even destroy-a satellite or space-craft if it collided (碰撞) with the junk.The International Space Station has to regularly change its orbit to avoid space junk,
     Space junk might also be a danger to humans.During the last four months,three very large spacecraft have fallen to Earth.Fortunately,no one was hurt because the junk landed in the ocean.
