    The soybean prices ended higher this Monday as traders expect supplies to remain tight
    The actively traded July contract for soybeans rose 20 cents to settle at $14.85 a bushel.
    The U.S government’s weekly prediction for soybean exports was higher than traders expected, said Mike Zulo, president of a consulting company in Atchison Kansas
    Supplies for beans have been extraordinarily tight as China’s demand for soybean continues to increase even as U.S production stays relatively steady he said Soybean prices have risen 15 percent this year
    “That U.S.D.A. number caused the trade to refocus on just how razor-thin supplies are heading in to next fall’s harvest” Zulo said
    What can be inferred from the passage about next fall’s soybean harvest?

    A. It’s not worth noticing
    B. It will rise 15 percent
    C. It’s still uncertain
    D. It will be razor-thin

    答案:D
    解析:
    推断题。根据文段最后一段“That U.S.D.A. number caused the trade to refocus on just how razor-thin supplies are heading in to next fall’s harvest”我们可以知道下一个丰收季就会关注更加紧张的供应。A项错误,文段最后一句提到refocus。B项提到的15percent是说今年大豆价格上涨了15%。文段说未来一定供应更加紧张,C项错误。因此答案选D。

    解析:
    文章介绍最近科学家已经完善了太阳能光伏热能系统,现在新型的太阳能系统能将太 阳能转换为更多的电能和热能。第一段说明以往晶体硅太阳能电池在收集热能方面效率很 低。四个选项中,只有选用until(直到······为止)才符合上下文的意思。"...until now they(太阳能光伏热能系统)haven' t been very good at the heat-generating part compared to a stand-alone solar thermal collector.”该句意为:与太阳热能单机集热器相比,直到现在为止,太阳能光伏热 能系统在转换热能方面效率一直不是很高。
    本句说明了以往的太阳能光伏热能系统在转换热能方面效率低的原因:它们在较低的温 度下运转以冷却晶体硅太阳能电池,而这样能产生更多的电能却不能高效地收集热能。which指 代本句中“they operate at low temperatures to cool crystalline silicon solar cells”这句话的整个内容。
    本句说,good solar hot-water systems在收获能量方面比solar-electric system要好得多,从 经济学的角度上分析,成本就降低了。所以,选cost(成本)是对的。其他选项reward(报酬,回 报),bill (账单,清单,钞票)和pay(工资,薪水)均不符合语境。
    从本句末的“leaving little room for thermal applications”可推知答案。take up是固定词 组,表示“占据”。
    上一段说太阳能光伏热能系统有两个问题,即经济问题和空间问题。Joshua Pearce采 用另外一种硅来制造PVT应该是为了解决上述问题。故选solution(解决方法,处理手段)。 devise意为“发明,设计,想出”。
    known as sth是固定搭配,意为“被称为······”,符合语境。" amorphous silicon , commonly known as thin-film silicon”意为“非晶硅,通常被称为薄膜硅”。
    这里是说:采用薄膜硅制造的太阳能电池,电能的转换量虽然不如晶体硅太阳能电池, 但薄膜硅太阳能电池用硅量小,比较环保。require(需要)符合语境。retrieve(提取), merge(混 合),exchange(交换)放在这里均不合适。
    前面说的用硅量小、比较环保是薄膜硅太阳能电池的优点,而由下文的vulnerable (易受 攻击的)可知下面说的是薄膜硅太阳能电池的缺点,所以选C。
    expose...to意为“暴露······于”,是固定搭配。后文说“pretty much the worst possible effect for a solar cell(对太阳能电池来说这很可能是最糟的效应)",而根据常识,对太阳能电池 来说最糟的可能便是其构成材料经受不了日晒,所以选expose非常符合语境。
    暴露于光线下时,薄膜硅太阳能电池效能降低,这是导致该产品市场占有份额很小的 一个原因。选reasons为答案很合理。
    这里指Pearce和他的队员发现了一种通过将薄膜硅纳人一种新型的PVT来改变 Staebler-Wronski效应的方法。所以选Aa engineer around意为“改变······的基因结构”。
    为了克服Staebler-Wronski效应,Pearce和他的团队悉心改进光伏太阳热能系统的结 构。作者要写的应该是运用一种新型PVT,故选type(类型)。
    这里指将薄膜硅加热到太阳能加热器工作的温度,临近水的沸点······the boiling point of water指水的沸点。故选C。
    从上下文判断,采用加热薄膜硅的方法,就能解决Staebler-Wronski效应。overcome表 示“克服,解决”,符合语境。
    前文讲通过加热薄膜硅,Staebler-Wronski效应得到解决,这是一个好事,而本句中提到 " they also found that by baking the cell once a day",从语义连贯来看,这里应该是指提高了将太 阳能转换为电能的效率,否则应用转折词而非“also”这样的表示承接的词,故选D。 boost表示 “增加,促进,提高”。

    Better Solar Energy Systems: More Heat, More Light
    Solar photovoltaic thermal energy systems,or PVTs,generate both heat and electricity,but until 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,which 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 cost. And it's also a space problem:photovol-taic cells can take 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 engineer-ing,has devised a solution 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 as thin-film silicon.They don't create as much electricity, but they are lighter,flexible,and cheaper. And,because they require much less silicon,they have a greener footprint. Unfortunately,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 expose them to light-pretty much the worst possible effect for a solar cell,"Pearce explains,which is one of the reasons thin-film solar panels make up only a small fraction of the market.
    However,Pearce and his team found a way to engineer around the Staebler-Wronski effect by incorporating thin-film silicon in a new type 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 point of water,they could make thicker cells that largely overcame the Staebler-Wronski effect. When they applied the thin-fulm silicon directly to a solar thermal en-ergy collector,they also found that by baking the cell once a day,they boosted the solar cell's e-lectrical efficiency by over 10 percent.

    Which of the following statrnents is true?
    A: Thin-film silicon's electrical efficiency improves when heated up.
    B: New techniques have been developed to produce thin-film silicon.
    C: Thin-film silicon works efficiently at low temperature.
    D: A new material enlarging the Staebler-WronsKi effect has been created.

    答案:A
    解析:
    根据第一段“they haven't been very good at the heat-generating part...”可知,与太阳热能单机收集器相比,传统太阳能光伏热能系统在转换热能方面效率不是很高。


    根据第二段可知,光电管占去屋顶的所有空间,几乎没有空间留给热能的产出。因此,传统太阳能光伏热能系统存在的一个问题是,占用太多空间,即C选项。文章也提到好的太阳能热水系统比太阳能电力系统成本低得多,但并没有说传统太阳能光伏热能系统贵到人们买不起的程度,因此B项错误。故本题选C。


    根据第四段“...but they are lighter , flexible , and cheaper. And , because they requiremuch less silicon , they have a greener footprint.”可知,选项B,C,D在文中都直接提到,A 项没有提到。


    根据第五段可知,薄型太阳能板只占有市场的一少部分的原因是,当被暴露在光线下,那就意味着它们的能效会降低——这几乎是太阳能电池最可能糟糕的效应。


    通读文章最后一段可知,如果一天把太阳能电池加热一次,那么太阳能的电力效能会增加10%。即A选项正确,其他三项在文中并未提及。
