treated cows.Sometimes similar drugs are simply trying to fatten the animals in order to obtain a higher price on the market .Although the Food and Drug Administration(FDA) has tried repeatedly to control these procedures,the practices continue. 这篇文章主要在谈食物和添加剂 additives(add 原意是“加” ，添上名词后缀 tives,猜出该词含义为食品添
加剂)对人类健康的影响，food、additives 是关键词。
51.What is the main topic of the passage? A. food and our health B . food and additives C . food and cancer? D. food and culture
这一题是典型的主旨概括题，让我们概括文章的大意。在之前课堂上的讲解中，我们提到，拿到文章
先读每段首句，遇到转折词语“but”“however”“although”“though”等，注意转折之后是句子重点。文章的第一 句的大意：我们吃的食物对健康有着深远的影响(profound effects 深远的影响)，后出现转折，说到科学家让 食物更适合食用，但又不适合食用，引起思考。再看第二段开始，提到添加剂不是直接被我们食用的，都 在谈论食品和添加剂的问题，因此此题选 B
52.All of the following statements are true EXCEPT_____? A.Forty percent of cancer is caused by problems related to food.
B .Researchers have known about the potential danger of food additives for many years C .Weeat some of the food additives directly and some indirectly. D.Drugs are always given to animals for medical purposes.
这是一题事实细节题。文章第一段第三句话， “Some research has shown that perhaps eighty percent of cancer is related to the diet ，as well,especially cancer of colon” ，说到癌症与食物的关系是80%，与 A 选项 Forty percent40%冲突，因此选 A 53.Why do farmers give drugs to their animals? A. To speed up the growth of animals?
B . To make the animal fatter
C . To make the animals’meat fit to eat?
D. To make the animals’meat rich in nutrients
这是一道情景题。在课堂讲解中我们提到，一定要严格符合文意。在文章第二段，第三句话“ Sometimes
similar drugs are simply trying to fatten the animals in order to obtain a higher price on the market” ，“ fatten” 含
义是使某物变胖，B 选项提到了。D 选项是干扰项，虽然“rich”是富裕的意思，但是整句话的含义是让动物
的肉变得更有营养，与文意不符。因此此题选 B 54. It can be inferred from the passage that____? A. Scientist have made all the food fit to eat.
B . Only in recent years have people found that the food is related to one’s illness. C . All kinds of the cancer are related to the diet. D. Some additives are harmful to our health.
这是一道判断推理题，“inferred from”即推断的意思，课堂技巧上提到，在考试中为了节约时间，绝对
的表述项可以不选。四个选项中 BC 两项，发语词 All Only,语意绝对，且文章第一段 “That food related to illnesses is not a new discovery” 与 B 项不符，文章第一段第三句话， “ Some research has shown that perhaps
eighty percent of cancer is related to the diet ，as well,especially cancer of colon” 也与文意不符，不是所有癌症 都是食物引发的。A 选项说所有的食物都适合食用，与文章第一段第一句话“at the same time,made many food unfit to eat.” 意思不符，因此此题选 D
55.The word “this” in the second sentence of paragraph 2 most probably refers to____? A.Farmer
B .Penicillin C .Beef and poultry
D.The fact that farmer often give penicillin to a beef
这是一道词汇理解题，锁定“this”的位置，前面的 because 指代这里的 this 说的是导致下文在牛奶里发
现盘尼西林(青霉素)的原因，而原因必将是由人的行为产生，四个选项中，只有 D 选项提到了人的行为(农
民给牛喂盘尼西林)，盘尼西林的生词在课堂讲解中，我们也提到过，想必大家一定做出了正确的选择。此 题选 D
参考答案：BABDD Passage 2
We are leaving the Industrial Age,when nation took pride in building the biggest machines possible,and entering the Tiny Tech Age,where power and prosperity will get to those who make machines smaller and smaller.In this world,the rules of the ‘big’ world do not always apply ---insects walk on water and ants carry many times their own weight.Those who work in micromachine labs must wear surgical masks.lest they breathe in the tiny devices from work surfaces.
Tiny technologies are a key to the future of robot.The old science-fiction notion of a robot pictured a large machine that mimicked human form and thinking. But a visitor to the Artificial Intelligence Laboratory at the Massachusetts Institute of Technologyin Cambridge gains a truer glimpse of our robotic future,
Out of the corner of his eye,the visitor sees something zip across the floor and duck under a chair.It is Squirt,a robot scarcely a cubic inch in size,designed not to think but to react in preprogrammed ways to stimuli.Turn on the lights or make a noise and Squirt quickly runs for the nearest dark place it “sees”.Turn off the light and Squirt comes out a few minutes later in the direction from which its twin-microphone “ cars” last picked up noise.
From M.I.T.scientists,the idea is to invent micro-robots that are fast and cheap and that work without human supervision.Squirt developer Anita Flynn foresees micromachine servants mass-produced so cheaply that when one finally wears out ,you’ll be able to throw it away and by a new one.
As explorers in this strange microworld,scientists and engineers are seeking new ways to build machines in other fields such as medicine,manufacturing and aerospace.But the use of micromachines is not limited to
specialized fields alone.You’ll be able to buy a “smart” car onboard microcomputer to adjust the engine as temperature changes.Micromachines can make your home “ smart” too.They will tell your air conditioner how to adjust themselves for efficiency and minimal pollution.There are also microsensor wrist watcher that monitor heart rate,pulse and blood preesure.By “ thinking small” ,scientists and dreamers are enlarging and enriching the future all of us. 这篇文章主要在谈微电子科技的发展。
56.In Paragraph 2,the word” mimicked”is closest in meaing to____? A.imitate B .enjoy C .understand D.study
此题是词义理解题，我们在文章中锁定该词的位置， “The old science-fiction notion of a robot pictured a large machine that mimicked human form and thinking.” A imitate 模仿，B enjoy 喜欢，使喜悦 C understand 理
0 D 学习，文意是机器人是大的机器，去 mimicked 人类的行为和思想，A 最符合文意。 57.”Squirt” has all the following characteristics EXCEPT_____? A.cheap B . Tiny C .smart D. Fast
这是一道细节理解题。找到文章中的关键词“ Squirt”，在第三段出现。“ a cubic inch”一立方英寸，相当
于16立方厘米，选项中的 tiny 微小的，不符合文意，因此选 B。其他三项在文中可以找到。
58.It can be inferred from the passage that_____? A.the smaller the robots,the more in trend B .The bigger the robots,the more in trend
C .The smaller the robots,the more expensive D.The bigger the robots,the more expensive 这是一道判断推理题，“in trend” 是走向，趋势，AB 两项讨论的是机器人发展的趋势，CD 两项讨论的 是机器人的外形与价格，“ you’ll be able to throw it away and by a new one.”“From M.I.T.scientists,theidea is to invent micro-robots that are fast and cheap and that work without human supervision”，都暗示了我们机器人的价 格会日益便宜，而通篇在谈论的是外形越来越小，因此选 A
59.As mentioned in passage,micromachines can be seen in the field of____? A.agriculture and weather forecast
B .Manufacturing and education C .Households and banking D.Space and medicine 这是一道情景题。最后一段句首提到 “ As explorers in this strange
microworld,scientists and engineers are seeking new ways to build machines in other fields such as medicine,manufacturing and aerospace” ，提到了药品、
制造业和太空技术，D 选项涵盖了其中两项，选 D。 60.The main idea of the passage is to _____? A.describe how micromachines are made B .Introduce the application of micromachines C .Promote the development of micomachines D.Discuss the strength and weaknesses of micromachines
这是一道主旨概括题。观察选项，四个选项都提到了关键词 “micromachines” ，关键是前面的动词。 A
describe 形容了微型机器如何制造的，B 介绍了微型机器的应用，C 促进了微型机器的发展 D 讨论了微型机
器的优势和劣势。从文段中看，文章主要在谈微型机器的发展，选择 C 选项 参考答案：ABADC
四、资料分析【本部分解析由华图吴芒芒老师提供】
61.选 D。2011年我国社会服务支出同比增长率=16.65%+5.5%=22.15% 62.选 C。2011年农村最低生活保障支出=690.4/(1+13.76%)=606 63.选 D。农村最低生活保障月人均平均支出=690.4/5340.9*12=108
64.选 B。从第二段的第三句话可以看出，农村最低生活保障月平均保准增速为20.3%，城市的为14.77%，
从而高出的值=20.3%-14.77%=6.5%
65.选 C。排除法，从最后一段可以看出农村五保户分散供养比集中供养的人数要多。 66.选 B。从柱状图可以看出，教育支出的的柱子高度最高，从而支出最多。 67.选 C。2010年与2009相比变化幅度最大的就是交通运输，柱子高度下降明显。
