文章摘要:专家解题:2013年职称英语考试理工类A级完形填空历年真题及答案解析1,真有一堆人本事抢着要,而且黑一店运作能力一流,没本事所以才想此下策。其实这个时候就不要列战绩了,温格要走,各大主帅们都发声了,比如穆里尼奥说的话,我相信是发自内心的,在这个时刻,都应该对温格表示敬意。本来以为买了个胖虎,谁知道还是买了个水货,赛季前的几个进球都是对手轻敌不防守他在加上运气而已。,口径巡航导弹本来就是从俱乐部反舰导弹发展过来的鹰击18跟俱乐部有血缘关系,而且我们早就有远程巡航导弹的技术,只不过鹰击18是适用垂直发射潜射方式而已,这些对中国已经不是问题了。才200个要抗议的那绝大部分的人还是要独立的和平统一遥遥无期为有强攻。广东历来出技术型中场,容志行,彭伟国等人都是这样,自从恒大在中超低迷的情况下,到处挖国脚,用国脚加外援的模式混了几年,虽然拿了几年冠军,但是扼杀了广东足球的特点,对广东足球和中国足球肯定不是好事。。

  考题类型:完形填空
  Better Solar Energy Systems: More Heat, More Light
  Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but ______ (51) now they haven't been very good at the heat-generating part compared to a stand-alone solar thermal collector. That's because they operate at low temperatures to cool crystalline silicon solar cells, ______ (52) lets the silicon generate more electricity but isn't a very efficient way to gather heat.
  That's a problem of economics. Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower ______ (53). And it's also a space problem: photovoltaic cells can ______ (54) up all the space on the roof, leaving little room for thermal applications.
  In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a ______ (55) in the form of a better PVT made with a different kind of silicon. His research collaborators are Kunal Girotra from Thin Silicon in California and Michael Pathak and Stephen Harrison from Queen's University, Canada.
  Most solar panels are made with crystalline silicon, but you can also make solar cells out of amorphous silicon, commonly known______ (56) thin-film silicon. They don't create as much electricity, but they are lighter, flexible, and cheaper. And, because they ______ (57) much less silicon, they have a greener footprint. ______ (58), thin-film silicon solar cells are vulnerable to some bad-news physics in the form of the Staebler-Wronski effect.
  "That means that their efficiency drops when you______ (59) them to light-pretty much the worst possible effect for a solar cell," Pearce explains, which is one of the ______ (60) thin-film solar panels make up only a small fraction of the market.
  However, Pearce and his team found a ______ (61) to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new ______ (62) of PVT. You don't have to cool down thin-film silicon to make it work. In fact, Pearce's group discovered that by heating it to solar-thermal operating temperatures, near the boiling ______ (63) of water, they could make thicker cells that largely  ______ (64) the Staebler-Wronski effect. When they applied the thin-film silicon directly to a solar thermal energy collector, they also found that by baking the cell once a day, they  ______ (65) the solar cell's electrical efficiency by over 10 percent.
  51. (    )
  A. unless
  B. when
  C. if
  D. until
  专家解析:
  第一步:回归横线句子51,北京赛车投注:即:Solar photovoltaic thermal energy systems, or PVTs, generate both heat and electricity, but ______ (51) now they haven't been very good at the heat-generating part compared to a stand-alone solar thermal collector.
  第二步:对比分析四个选项,只有选项D能和横线后单词now搭配成until now,表示直到现在的意思,故正确答案为D选项。
  52. (    )
  A. which
  B. what
  C. that
  D. who
  专家解析:
  第一步:回归横线句子52即:That's because they operate at low temperatures to cool crystalline silicon solar cells, ______ (52) lets the silicon generate more electricity but isn't a very efficient way to gather heat.
  第二步:对比分析四个选项,四个选项都是关系词,横线后句子缺少主语,并且横线前有标点逗号,可见这里应该填入关系词which,故正确答案为A选项。

  B. cost
  C. bill
  D. pay
  专家解析:
  第一步:回归横线句子53,即:Good solar hot-water systems can harvest much more energy than a solar-electric system at a substantially lower ______ (53).句子的意思是:好的solar hot-water systems比solar-electric system能以一个更低的____获利很多。
  第二步:对比分析四个选项,A选项是报酬的意思,B选项是账单的意思,B选项是成本的意思,D选项是付款的意思;对比可见,选项B填入此处符合原文意思,故正确答案为B选项。

  B. set
  C. take
  D. live
  专家解析:
  第一步:回归横线句子54,即:……photovoltaic cells can ______ (54) up all the space on the roof, leaving little room for thermal applications. 句子的意思是:photovoltaic cells会____屋顶所有的地方,为thermal applications几乎不留空间。
  第二步:对比分析四个选项,四个选项都能和横线后单词up组成短语,A选项move up是升职的意思,B选项set up是建立的意思,C选项take up是占用的意思,D选项live up是实践的意思;对比可见,选项C填入此处符合原文意思,故正确答案为C选项。
  55. (    )
  A. decision
  B. solution
  C. suggestion
  D. qualification
  专家解析:
  第一步:回归横线句子55,即:In a pair of studies, Joshua Pearce, an associate professor of materials science and engineering, has devised a ______ (55) in the form of a better PVT made with a different kind of silicon.句子的意思是:在一组研究中,Joshua Pearce……已经想出了一个____,用不同种类silicon促成的更好的PVT形式。
  第二步:对比分析四个选项,A选项是决定的意思,C选项是建议的意思,D选项是资格的意思,B选项是解决办法的意思;对比可见,选项B填入此处符合原文意思,故正确答案为B选项。
