2019年大学英语四级考试阅读模拟试题：如何写作
Learning how to write is like taking a course in public speaking. I'd ask whether anyone in class had evertaken such a course. Always a few hands would go up.
"What did you learn in that course?" I'd ask.
"Well, the main thing was learning how to face an audience: not to be inhibited (拘谨)... not to be nervous. "
Exactly, when you take a course in public speaking nowadays, you don't hear much about grammar and vocabulary. Instead. you're taught how not to be afraid or embarrassed, how to speak without a prepared script. how to read out to the live audience before you. Public speaking is a matter of overcoming your long-standing nervous inhibitions.
The same is true of writing. The point of the whole thing is to overcome your nervous inhibitions, to break through the invisible barrier that separates you from the person who’ll read what you wrote. You must learn to sit in front of your typewriter of dictating machine and read out to the person at the other end of the line.
Of course, in public speaking with the audience right in front of you, the problem is easier. You can lookat them and talk to them directly. In writing, you 're alone. It needs an effort of your experience or imagination to take hold of that other person and talk to him or her. But that effort is necessary or at least it' s necessary until you've reached the point when you quite naturally and unconsciously "talk on paper".

参考答案及解析
1.[C] 事实细节题。原文第4段,特别是第4段的最后一句表明c为正确选项。本题稍具干扰性的是D，该选项中的live一词在第4段第2句末尾也有出现，但事实上D与该句的意思不相同。
2.[A] 事实细节题。本题考查对比处。第5段第1句表明下一句就是演讲和写作的相似之处，而A就是对该句的同义替换。其他选项并未按照题目的要求对比演讲与写作，只是说明了写作必须做的，因此都不正确。
3.[A] 推理判断题。本题考查对比处。结尾段对比了演讲和写作的不同之处，第1、2句和第3、4句形成了内在的对比关系，由此可推断写作比演讲更需要经验和努力，因此可确定A正确，而C不正确。虽然在这一段可找到effort和naturally等词，但原文并没有从是否要付出同样多的努力(B)或是否自然(D)等方面对比演讲与写作，因此B和D也不正确。
4.[D] 推理判断题。根据最后一句中的“在纸上说话”,可推断作者认为写作如在纸上作演讲一样，因此D正确。A中的Few students与事实不符;B中的speak with a script在文中未有提及;C中的separated by a barrier错误。
5.[D] 主旨大意题。文章的开头句就是全文的主题句，作者在前四段说明如何演讲，从第5段开始，作者转向说明如何写作,文章的结尾句对开头句做出了呼应。作者之所以将演讲和写作过程做比较是为了让自己的观点更容易、更生动地被读者明白和接受，因此本文的中心内容是围绕写作，而不是演讲。其余选项虽然文中都有提及，但只是各个具体的侧面内容，不能概括全文大意。
2019年大学英语四级考试阅读模拟试题：农业技术
Even plants can run a fever, especially when they're under attack by insects or
disease. But unlike humans, plants can have their temperature taken from 3,000 feet away-straight up. A decade ago, adapting the infrared (红外线) scanning technology developed for military purposes and other satellites, physicist Stephen Paley came up with a quick way to take the temperature of crops to determine which ones are under stress. The goal was to let farmers precisely target pesticide(杀虫剂) spraying rather than rain poison on a whole field, which invariably includes plants that don't have pest(害虫) problems.
Even better, Paley's Remote Scanning Services Company could detect crop problems
before they became visible to the eye. Mounted on a plane flown at 3,000 feet at night ,an infrared scanner measured the heat emitted by crops. The data were transformed into a color-coded map showing where plants were running "fevers".Farmers could then spot-spray, using 50 to 70 percent less pesticide than they otherwise would.
The bad news is that Paley's company closed down in 1984, after only three years. Farmers resisted the new technology and long-term backers were hard to find.But with the renewed concern about pesticides on produce, and refinements in infrared scanning, Paley hopes to get back into operation.Agriculture experts have no doubt the technology works. "This technique can be used on 75 percent of agricultural land in the United States, "says George Oerther of Texas A&M. Ray Jackson, who recently retired from the Department of Agriculture, thinks.remote infrared crop scanning could be adopted by the end of the decade. But only if Paley finds the financial backing which he failed to obtain 10 years ago.
这是一篇说明文。文章一开头就介绍了原用于军事和卫星的红外线扫描技术，如今被用在农业上。通过远距离测量植物的温度来判断农作物是否遭受虫害和疾病。在第二段中指出，物理学家帕里组建了帕里远红外扫描服务公司，来专门探测农业方面的情况。最后他的公司在三年后被迫关闭，主要是因为缺乏资金。另外，农民们也一时不能接受这种新技术。作者期待将来有一天可以解决财政困难，将这一新技术重新用到农业上去。

参考答案及解析
1、[答案及分析]：[C]。词组理解题。本文第一段的第一句话谈到：“Even plants can run fever...by insects or disease.”这就告诉了我们植物升高温度的原因。本句所问的也正是这个原因。因此，C正告诉了我们这一点，所以C是正确答案。
2、[答案及分析]：[D]词汇理解题。在第一段的原文中“The goal was to let farmers precisely target pesticide spraying...”其中的意思是“确定”(虫害发生的地方)”而答案D是说“要确定问题所在地区”，信息与本文相符，故D为正确答案;而A、B、C都与本文不符。
3、[答案及分析]：[A]。判断题。问农民通过何种方式可节省杀虫剂。在文章的第二段中谈到帕里远红外线扫描服务公司利用飞机上的远红外线扫描仪夜间在3000英尺的高度探测到庄稼的情况，然后可将这些情况提供给农民，农民可喷洒农药，这样只使用原来农药量的50%-70%就足够了。故答案A的信息与本文相符;而B、C、D均不正确。
4、[答案及分析]：[C]。词汇理解题。问远红外扫描技术用于农业上时遇到的阻力，原因何在。在本文最后段中指出：1984年，帕里公司被迫关闭的原因一资金缺乏。并呼吁说：“But only if Paley finds the financial backing which he failed to obtain 10years ago.”其中financial backing的意思与本题C的“financial support”相同。所以答案C正确。
5、[答案及分析]：[B]。正误判断题。问远红外扫描技术有可能重新用于农业，原因何在。在文章最后一段中说“But with the renewed concern...to get back into operation”由此可明显看出，B的信息与本文内容相符，所以答案B是正确的;而A、C、D都与本文不符。
