15.Since people first sent rockets into space in the 1950s,we have been leaving behind all sorts of things.Some of them,like the cameras,(61)were lost(lose) by astronauts when they did work outside their spaceship.But much of the space junk is made up of little pieces of things(62)that/whichwere once bigger objects,until they struck each other and broke apart.Some things we send into space fall back toward the earth and burn up in the atmosphere.(63) Butlarger pieces sometimes survive the extreme heat and hit the ground or the ocean(64)at/withgreat speeds.So there is always concern that something may fall from the sky and will be(65) harmful(harm) to us.
But space junk(66)falling(fall) on housetops (屋顶) is not the biggest worry.Scientists are concerned about what will happen when (67)anempty rocket strikes another while orbiting (绕…运行) the earth.Two big things become many smaller things.They then hit(68)otherthings.The pieces get smaller and smaller until(69)they form a cloud of junk that blocks the path of future space vehicles.
So what can be done to clean up the space around our planet?Scientists have been worried(70)aboutthe space junk for many years.Right now,the costs of the clean-up have been too great.
分析 本文主要介绍太空垃圾的形成原因和对太空造成的危害,此类问题使科学家很担心,因为清理这些太空垃圾的费用是很高的.
解答 61.were lost 考查动词时态和语态.some of them与lose之间是动宾关系,且事情已经发生,要用一般过去时态的被动语态,且主语some of them是复数,助动词用were.
62.that/which 考查定语从句.分析句子结构可知这是一个定语从句,先行词pieces指物,且在从句中作主语,用关系代词that/which.
63.But 考查连词.前后两个单句之间是转折关系,要用连词but.
64.at/with 考查介词.at/with great speeds意为"以极快的速度",是习惯搭配.
65.harmful 考查形容词.be harmful to意为"对…有害",是固定搭配.
66.falling 考查现在分词.junk与fall之间是主谓关系,用现在分词短语falling on housetops修饰junk.
67.an 考查冠词.rocket意为"火箭",是可数名词,单数形式前加不定冠词a,因其前的单词empty的读音是以发元音开头,用不定冠词an.
68.other 考查形容词.根据句意:它们撞击其它的物体.
69.they 考查代词.they指代前文的pieces.
70.about 考查介词.worry about意为"担忧,烦恼",是固定搭配.
