Inventor of LED
When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys, his colleagues thought he was unrealistic. Today, his discovery of light-emitting diodes, or LEDs, are used in everything from DVDs to alarm clocks to airports. Dozens of his students have continued his work, developing lighting used in traffic lights and other everyday technology.
“Anytime you get an award.big or little.it’s always a surprise.”Holonyrak said.
Holonyak, 75，was a student of John Bardeen，an inventor of the transistor, in the early 1950s.After graduate school, Holonyak worked at Ben Labs.He later went to General Electric，where he invented a switch now widely used in house dimmer switches.
Later, Holonyak started 1ooking into how semiconductors could be used to generate 1ight.But while his colleagues were 1ooking at how to generate invisible light，he wanted to generate visible light.The LEDS he invented in 1962 now last about 10 times longer than incandescent bulbs, and are more environmentally friendly and cost effective.
Holonyak，now a professor of electrical and computer engineering and physics at the University of Illinois，said he suspected that LEDs would become as commonplace as they are today，but didn’t realize how many uses they would have.
“You don’t know in the beginning.YOU think you’re doing something important.you think it’s worth doing，but you really can’t tell what the big payoff is going to be，and when，and how.You just don’t know，”he said.
The Lemelson.MIT Program also recognized Edith Flanigen，75，with the$1 00，000
Lemelson-MIT Lifetime Achievement Award for her work on a new generation of“molecular sieves，”that can separate molecules by size.

Soot and Snow：a Hot Combination
l New research from NASA scientists suggests emissions of black soot alter the way sunlight reflects off snow.According to a computer simulation，black soot may be responsible for 25 percent of observed global warming over the past century.
2 Soot in the higher latitudes of the Earth。where ice is more common，absorbs more of the sun’s energy and warmth than an icy, white background.Dark-colored black carbon，or soot，absorbs sunlight，while lighter colored ice reflects sunlight.
3 Soot in areas with snow and ice may play all important role in climate change.Als0，if snow and ice covered areas begin melting。the warming effect increases，as the soot becomes more concentrated on the snow surface.“This provides a positive feedback，as glaciers and ice sheet smelt,they tend to get even dirtier,” said Dr.James Hansen，a researcher at NASA’s Goddard Institute for Space Studies，NewYork.
4 Hansen found soot’s effect on snow albedo(solar energy reflected back to space)，which may be contributing to trends toward early springs in the Northern Hemisphere，such as thinning Arctic sea ice，melting glaciers and permafrost.Soot also is believed to play a role in changes in the atmosphere above the oceans and land.
5 “Black carbon reduces the amount of energy reflected by snow back into space，thus heating the snow surface more than if there were no black carbon~，”Hansen said.Soot’s increased absorption of solar energy is especially effective in warming the world’s climate. “This forcing is unusually effective，causing twice as much global warming as a carbon.dioxide forcing of the same magnitude，”Hansen noted.
6 Hansen cautioned.although the role of soot in altering global climate is substantial，it does not alter the fact that greenhouse gases are the primary cause of climate warming during the past century.Such gases are expected to be the largest climate forcing f10r也e rest of this century.
7 The researchers found that observed warming in the Northern Hemisphere was 1arge in the winter and spring at middle and high latitudes.These observations were consistent with the researchers’ climate model simulations，which showed some of the largest warming effects occurred when there were heavy snow cover and sufficient sunlight.

Storms Sink Ships
Rescuers have found the bodies of over 130 people killed in two ferry disasters in
Bangladesh.The accidents happened during a storm that hit the country on April 21.Hundreds more are missing or feared dead.
The two ferries sank in different rivers near the capital city of Dhakfi as strong winds and rain hit the South Asian country.
The government has since banned a11 ferries and other boats from traveling at night during the April-May stormy season. .
One of the ferries，MV Mitali，was carrying far more people than it was supposed to.About 400 passengers fitted into a space made for just 300，police said.The second ferry carried about 1 00 passengers.
“The number of deaths is certain to rise.”said an official in charge of the rescue work.“No one really knows how many people were on board‘the ferry or how many of them survived.’’
Ferries in Bangladesh don’t always keep passenger lists，making it difficult to determine the exact number of people on board.
Besides the ferry accidents，at least 40 people were killed and 400 injured by lightning strikes.falling houses and trees and the sinking of small boats.
Storms are common this time of year in Bangladesh，as are boating accidents.Ferry
disasters take away hundreds of lives every year in a nation of 130 million people.
Officials blame these river accidents on a lack of safety measures.too many passengers in boats and not enough checks on weather conditions.
Ferries are a common means of transport in Bangladesh.It is a country covered by about 230 rivers.Some 20，000 ferries use the nation’s Waterways every year.And many of them are dangerously overcrowded.
Since 1977, more than 3.000 people have died in some 260 boating accidents.
词汇：
ferry n.渡船
waterway n.水路，水道
Bangladesh：孟加拉国，位于南亚
练习：
1.How many people have been found dead in the two ferry disasters?
A、Over 130.

Snow Ranger
The two things – snow and mountains – which are needed for a ski area are the two things that cause avalanches, large mass of snow and ice crushing down the side of a mountain—often called "White Death."
It was the threat of the avalanche and its record as a killer of man in the western mountains that created the snow ranger. He first started on avalanche control work in the winter of 1937 –38 at Alta, Utah, in Wasatch National Forest.
This mountain valley was becoming well known to skiers. It was dangerous. In fact, more than 120 persons had lost their lives in 1936 and another 200 died in 1937 as a result of avalanches before it became a major ski area.
Thus, development of Alta and other major ski resorts in the west was dependent upon controlling the avalanche. The Forest Service set out to do it, and did, with its corps of snow rangers.
It takes many things to make a snow ranger. The snow ranger must be in excellent physical condition. He must be a good skier and a skilled mountain climber He should have at least a high school education, and the more college courses in geology, physics, and related fields he has, the better.
He studies snow, terrain, wind, and weather. He learns the conditions that produce avalanches. He learns to forecast avalanches and to bring them roaring on down the mountainsides to reduce their killing strength. . The snow ranger learns to do this by using artillery, by blasting with TNT, and by the difficult and skillful art of skiing avalanches down.
The snow ranger, dressed in a green parka which has a bright yellow shoulder patch, means safety for people on ski slopes. He pulls the trigger on a 75 mm. Recoilless rifle, skis waist deep in powder testing snow stability, or talks with the ski area’s operator as he goes about his work to protect the public from the hazards of deep snow on steep mountain slopes.
1. The snow rangers are employees of
A) the Forest Service.
B) the Resource Bureau.
C) the Tourist Board.
D) the Sports Bureau.
2.A snow ranger himself must be
A) a college graduate.
B) a physicist.
C) a geologist.
D) a mountaineer.
3. A snow ranger uses very powerful guns
A) to warn skiers of an approaching avalanche.
B) to signal for help in an emergency.
C) to create an avalanche.
D) to communicate with the ski area’ operator.
4. What is the primary duty of the snow ranger?
A) To make sure ski area operators are following safety rules.
B) To predict and control avalanches in mountainous areas.
C) To check skis and repair them.
D) To forecast the weather.
5.The passage implies that a snow ranger
A) knows how to use a pistol.
B) must write lengthy reports on his work.
C) may travel many miles when he is on duty.
D) has a long working day.

Don’t rely on plankton to save the planet
Encouraging plankton growth in the ocean has been touted by some as a promising way to remove carbon dioxide from the atmosphere. ___1___.
Adding iron to patched of ocean can make plankton bloom temporarily. The microscopic organisms suck up dissolved carbon dioxide from the water, which in turn is replaced by carbon dioxide from the air. ___2___.
Jorge Sarmiento from Princeton and his colleagues developed a complex computer model to analyze how factors such as ocean chemistry and water circulation would affect the process if 160,000 square kilometers of ocean were seeded with iron for a month. ___3__.
In their scenario, which covers an area 10 times as big as the largest experiment of this kind ever proposed, fertilizing the ocean removes 1 million tons of carbon from the atmosphere-- just 0.2 percent of the carbon dioxide humankind spews out each month.
Rough estimates in the past have predicted similarly disappointing results. __4__ Says Sallie Chisholm, an environmental engineer from the Massachusetts Institute of Technology. "But the take-home message is the same. ___5___."
A. Its opponents argue, however, that it will stop global warming.
B. Its opponents fear that will damage the marine ecosystem, and now a computer model shows that the trick would also be remarkably inefficient.
C. As plankton die and settle on the ocean floor, their carbon is supposedly locked up in the seabed.
D. They found that 100 years later only between 2 and 11 percent of the extra carbon that was originally taken up plankton had actually been removed from the atmosphere.
E. "These are newer and better models,"
F. Ocean fertilization is not the answer to global warming.

答案及解析
下面共有15句子，每个句子均有一个词或短语划有底横线，请从每个句子后面所给的四个选项中选择一个与划线部分意义最相近的词或短语。答案一律涂在答题卡相应的位置上。
1. B.分析：借助划线短语中的基本词汇含义猜测短语可能的含义为“为了钱和爱”。而这四个备选答案中只有答案B (at any price/以任何代价)在基本用词上(price)与划线短语一致，而且在句意上也合理。该句含义是“某些流行书籍的首印版是无论如何也很难得到的。”
2. C.分析：该题考察与虚拟语气相关的常见动词。 recommend是“推荐”; order是“命令”; insist是“坚持”; demand 是“要求”;suggest 是“建议”。只有suggest与recommend语义相近，所以答案为C。
3. B. 分析：借助与划线词直接相关的搭配结构含义(..情况)判断B(艰苦的)。sincere是“真诚的”; hard是“艰苦的”; strict是“严肃的”; tight是“紧的”。
4. C.分析：借助句意(这座房子在风中..如磐石)判断答案C(稳固的)。exceptional adj
特别的;异常的; continuous adj.连续的, 持续的
5. D。 分析：借助联想法。画线词shine与常见词汇sunshine(阳光)有关。又因shine 的宾语是鞋子，所以推测shine 的含义与“使鞋子光亮”有关。所以polish(擦亮)D是答案。另外：lighten是“to make or become light or brighter/减轻(负担); 缓和, 使轻松, 使愉快，(使能发光的东西)变亮”，而wash是(洗); clean是(使干净)。
6. B.分析：借助句意(20世纪70年代初期当Barbara Jordan在参议院里任职的时候，他就支持有关禁止种族歧视和解决环境问题的立法)判断答案B(禁止)。Forbid(forbade; forbidden) vt.禁止，不准，不许;Handle vt拿;处理;应付;控制; Ban vt./n.(法律上)禁止
7.A. 分析：该句含义是“昨天在那家商店里为我服务的是一位美丽的女服务员”。attend to v. 倾听,关心, 照顾; wait on v.服侍, 招待
8. D.分析：annoying adj.恼人的, 讨厌的; Horrifying vt令人感到恐怖的; painful adj.疼痛的, 使痛苦的; disturbing adj.烦扰的
9. A.分析：借助句意(这些是我们这样做的..)判断A最合适。Motive n动机;目的; Target n.目标, 对象; 笑柄(for); argument n.争论, 辩论, 论据, 论点, ～ (for ,against); pursuit n.
追逐，追寻
10. A. 分析：根据搭配结构含义(..事件)判断A(控制)合适。该句含义是“成功的领导者是事先控制事件而不是事后才做反应”。 Contribute v.捐助, 捐献, 贡献, 投稿; convey vt.搬运, 传达; contact n.接触, 联系vt.接触, 联系
11. C. 分析：根据句意(这个例证是论据中的一个主要例证)判断C(主要的)合适。fundamental
adj.基础的, 基本的; impressive adj.给人深刻印象的; public n.公众adj.公众的, 公共的;slight adj.轻微的, 微小的
12. C。分析：根据句意(医学依靠其他领域获得它所需要的基本信息，尤其是这些领域中的一些从事专门研究的领域)判断C(尤其是)最合适。Conventionally adv.按照惯例;inevitably adv.不可避免;obviously adv.明显地
13. A.分析：astonish 和amaze是近义词，表示“使惊讶”， amount作动词用时经常和介词to连用，表示 “总计, 等于”， amuse是“使愉快”，approach可用作动词表示“接近”，或作名词表示“方法，途径”。该句含义是“我们很惊讶的得知他们的足球队曾经赢得过冠军。”
14.B。分析：steady 和stable是近义词，都可表示“稳定的”， 所以可以相互排除掉。再根据构词法：plentiful = plenti(y) + ful 判断B的含义是“大量的”。借助句意“在这个国家里有大量的廉价劳动力”判断B最合适。
15.D。分析：crucial“至关紧要的”和 urgent“紧急的”含义最接近。该句句意是“任何经济体系所面临的最至关紧要的的问题是如何使用它稀少的资源”。Puzzling adj.(使)迷惑的, (使)为难的; terrifying adj.使感到恐怖的;

Inventor of LED
1. A.利用题干中的核心词colleagues作为答案线索词，这样找到答案相关句：When Nick Holonyak set out to create a new kind of visible lighting using semiconductor alloys，his colleagues thought he was unrealistic(不可行的， 不切实际的).(该句内容基本上与题干中的内容一致，但还需要确认题干中提到的LEDs就visible lighting using semiconductor alloys)Today，his discovery of light-emitting diodes，or LEDs, are used in everything from DVDs to alarm clocks to airports.(根据该句内容可以推断出LEDs就是前句中提到的visible lighting using semiconductor alloys)因此判断问题句的说法正确。
2.C.分析：需要注意题干中出现的修饰词sooner or later(迟早)。利用题干中提到的新信息—他的学生，作为答案线索，这样发现答案相关句：Dozens of his students have continued his work，developing lighting used in traffic lights and other everyday technology.
On April 23，2004, Holonyak received the $500，000 Lemelson-MIT Prize at a ceremony in Washington. (该句与题干中提到的“Holonyak相信...”无关)在下文的内容中也没有看到有关“Holonyak对他学生的期望”的话语， 因此判断该句的内容为“没提到”。
3.B分析：利用题干中出现的特征词-- early 1950s作为答案线索，这样找到答案相关句：Holonyak, 75，was a student of John Bardeen，an inventor of the transistor(晶体管), in the early 1950s.(该句所反映的内容是：John Bardeen是20世纪50年代初期晶体管的发明者，因此问题句的内容与原文的内容不一致。)
4.A.分析：利用题干中出现的核心词popular作为答案线索，这样发现文章中并没有popular这个词出现。因为问题句是观点句，这样的句子内容往往需要考生根据相关内容进行推断，因此注意文章中描述Holonyak态度的句子，这样找到答案相关句：Holonyak，now a professor of electrical and computer engineering and physics at the University of Illinois，said he suspected that LEDs would become as commonplace (常见的)as they are today，but didn’t realize how many uses they would have.(but引出的句子的句意(但是没有意识到它们将会有这么多种用途)揭示suspect的含义应该是“猜想”，因此整个划线句的内容(他曾猜想到LEDS的用途会非常的普遍，就象现在这样子)与问题句的内容一致)
5.C.分析：该句中也是没有明显的特征词，利用句中出现的核心词interested作为答案线索，这样发现文章中没有出现该词，也没有出现与该词词义相关的其他词，而文章中也没有涉及到这方面的内容，因此判断该句的说法为“没提到”。
6. C.分析：利用题干中出现的特征词Edith Flanigen作为答案线索，这样发现答案相关句： The Lemelson-MIT Program also recognized Edith Flanigen，75，with the$1 00，000 Lemelson-MIT Lifetime Achievement Award for her work on a new generation of“molecular sieves，”that can separate molecules by size.(但是该句的内容是说“Edith Flanigen”对新一代的“分子筛”的研制作出了杰出的工作，没有说她是LEDs的合作发明者。)
7.B.分析：该题提到了有关Lemelson-MIT奖，而且具体提到了该奖项的存在时间，因此判断该题很可能会需要考生根据相关句子进行判断。利用题干中出现的特征词Lemelson-MIT作为答案线索，这样发现答案相关句：On April 23，2004, Holonyak received the $500，000 Lemelson-MIT Prize at a ceremony in Washington.This marks the 1Oth year that the Lemelson-MIT Program at the Massachusetts Institute of Technology fMIT has given the award to prominent inventors.根据该句内容判断Lemelson-MIT奖成立的时间是1994年，因此问题句中说的“Lemelson-MIT奖有100多年的历史”与原文内容矛盾。
阅读下面这篇短文，短文后有2项测试任务：(1)1---4 题要求从所给的6个选项中为第2--5 段每段选择1个正确的小标题;(2)第5--8题要求从所给的6个选项中选择4个正确的选项，分别完成每个句子。请将答案涂在答题卡相应的位置上。
1.C 第三段解释了为什么soot会增加地球升温效应。
2.A 第四段介绍了soot在两方面起的作用：(1)soot增加了雪吸收太阳能量和热量的能力;(2)soot导致海洋和陆地上空的大气层发生变化。
3.F第六段的关键句子是：“…greenhouse gases are the primary cause of climate warming during the past century.” .
4.B第七段介绍了在研究北半球的纬度、雪覆盖面和日照诸因素与气温升高之间的关系方面取得的成果。
5.B 选择B的依据是第一段。有关的句子是：。“…black soot may be responsible for 25 percent of observed global warming over the past century.”选项B中用了过去式contributed，也是选B的一个线索，因为第五题的题干中有in me twentieth century，这个时间状语要求谓语动词用过去式，而4个选项中只有B项的动词用的是过去式。
6.E Hansen cautioned和greenhouse gases仅出现在第六段。该段的大意是：虽然煤烟在改变全球气候方面所起的作用相当显著，但是上个世纪气温上升的主要因素还是温室气体。选项E概括了第六段的意思。
7.D 本题答案的依据是第二段第一句。
8.A本题答案的依据是第五段的下列句子： Soot’s increased absorption of solar energy is especially effective in warming the world’s climate.“This forcing is unusually effective， causing twice as much global warming as a carbon-dioxide forcing of the same magnitude，”Harisen noted.

第1篇
Storms Sink Ships
1. A 该题问的是：在两次渡船失事中已发现多少人死了?第一段第一个句子说到“救援人员已经找到了在盂加拉国的两次渡船失事中的130多人的尸体”。当然，实际的死亡人数还要高。
2• C。该题问的是：这两次渡船失事发生在什么时候?这是一道推理题。文章中没有一个句子直接地提供了这方面的信息。但是第三段间接地传递了这方面的信崽：政府自此后禁止所有的渡船和其他船只在四五月的暴风季节夜航。
3• D。 该题问的是：渡船MV Mitali设计载客量是多少?答案在第四段的第二句：把大约400个旅客装进了只能容纳300个旅客的空间。
4 D。 该题问的是：官员们解释船只失事的原因是什么?倒数第三段说到了缺乏安全措施
5.C.该题问的是： 下面有关这两次渡船失事的说法哪种是错的?第5段有这样一句话：没有人真正知道当时有多少人在船上，也不知道有多少人还活着，第6段是这么说的：盂加拉国的渡船不是总能留下乘客的名单的，使得确认船上确切的人数很困难。

第3篇
Snow Ranger
1. A。该题问“‘雪地管理员’受雇于谁?”。借助备选答案的特点：答案都是专有名词(首字母都大写且名词前有定冠词the)，所以可以在文章中迅速查找首字母大写的专有名词，然后确认答案。很容易在第四段中发现" The Forest Service set out to do it, and did, with its crops of snow rangers"，该句说“森林服务部和它的护雪场工作人员队伍一起着手做这件事(指控制雪崩)并且做到了”，所以从这句话确认答案是A。
2.D.该题问“‘雪地管理员’必须是什么样的人?”。这道题可以依据常识判断：备选答案中：A说“大学毕业生”;B说“物理学家”;C说“地质学家”;D说“登山运动员”。依据常识，D最合理，所以选择D。而如果依据原文：文章中的第五段的段首句说“要成为雪地管理员需要很多的条件”，所以判断答案相关句应在该段中。该段说“雪地管理员应是优秀的登山运动员” ，所以D是答案。
3.C.该题问“‘雪地管理员’使用有很强杀伤力的枪?”。这道题可以依据线索词在句中寻找答案。线索词： powerful gun(很强杀伤力的枪)或其与其近义的短语。于是在第6段中的最后一行中发现gun的近义词artillery，所以找到了答案相关句。该句的前一句说“雪地管理员要使雪崩沿着山坡轰隆隆地滚下” ，所以C是答案，C说“ 制造雪崩”。
4. B。该题问“‘雪地管理员’的主要责任是什么?”。这道题可以依据常识判断：备选答案中：A说“确保滑雪场地的操作员遵守安全规则”;B说“预测和控制山区的雪崩”;C说“检查并修理雪橇”;D说“预测天气”。依据常识和前一题判断B最合理。
5.C。该题问“该短文暗示‘雪地管理员’怎样?”。这道题可以依据常识判断：备选答案中：A说“知道怎样使用手枪”;B说“必须写有关其工作的长篇报告”;C说“值班时可能会滑行数英里”;D说“工作时间很长”。依据常识和已有的对文章的了解推断C最合理。而如果依据原文：文章中提到了“枪”的使用，所以A不是答案。 在第5段中说“雪地管理员”必须是身体素质好”所以暗示答案C。
