14．About five years ago，an American electrical engineer named Scott Brusaw and his wife Julie came up with the idea of putting solar panels（控制板）on the ground rather than the roof．Then they began to develop the Solar Roadway．The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions，along with power and data delivery．They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being used to build and resurface current roads can be used to build the Solar Roadways．
Each Solar Road Panel measures roughly 4 meters by 4 meters and contains a microprocessor that monitors and controls the panel，while communicating with neighboring panels and the vehicles travelling overhead．The inventors suggest that this provides a communications device every 4 meters on every road，which could be used for example to warn drivers of cars which are moving across a centre line and various other speed control problems．The top of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions（抓地力）they need．
According to the inventors，the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop，or at any business that has paved Solar Road Panels in their parking lots．
The inventors say their Solar Roadway has many functions and advantages from main roads to driveways，parking lots，bike paths，sidewalks and runways．The Federal Highway Administration has given Brusaw＄100，000 to develop the invention and Brusaw hopes to build a smart-road parking lot in the coming spring．
71．In the inventors'opinion，the Solar RoadwayD．
A．is too expensive to build at present           
B．will bring them a large sum of money
C．can provide as many data as present computers   
D．costs no more money than current roads
72．The underlined word"they"in Paragraph 2 refers toC．
A．the panels      B．the inventors        C．the vehicles    D．the researchers
73．The Solar Roadway includes all the following advantages exceptA．
A．helping drivers communicate with each other while driving
B．providing safer driving conditions
C．creating and carrying clean renewable electricity
D．warning drivers of various speed control problems
74．It can be inferred from the text thatB．
A．the Solar Roadway has already been put into use 
B．the Solar Roadway is not available for gas-powered cars
C．＄100，000 is only enough to build a smart-road parking lot
D．future electric vehicles can be charged anytime and anywhere
75．What can be the best title for the text？B
A．The great changes on the roadway            
B．Solar-powered smart road of the future
C．The influence the Solar Roadway has on people   
D．The Solar Road-a much faster road．

分析 本文屬于說明文閱讀，作者通過這篇文章主要向我們描述了工程師們建立太陽能巷道的一個(gè)設(shè)想，他們希望能在不就得了將來實(shí)現(xiàn)幫助世人．

解答 71．D．細(xì)節(jié)理解題．根據(jù)文章第一段"They predict that the Solar Roadway will pay for itself through the generation of electricity along with other forms of income and that the same money that is being usedto build and resurface current roads can be used to build the Solar Roadways．"可以看出，此項(xiàng)發(fā)明，并不用花額外的錢．故選D．
72．C．推斷判斷題．句中的Them是一個(gè)代詞，主要指代的是上文提過的內(nèi)容，所以將這個(gè)詞放在整句中分析，"Thetop of the Solar Road panels is made of super-strong glass that would offer vehicles the tractions（抓地力） they need．"句中的 the Solar Road panels 是由超強(qiáng)的玻璃制成的，它向交通車輛提供（車輛）所需的地抓力；故選C．
73．A．推理判斷題．根據(jù)原文中第三段"According to the inventors，the Solar Roadway creates and carries clean renewable electricity and therefore electric vehicles can be recharged at any conveniently located rest stop，or at any business that has paved Solar Road Panels in their parking lots．"可知太陽能巷道并不能幫助司機(jī)們互相交流；故選B．
74．B．推理判斷題．根據(jù)文章第一段"The Solar Roadway is an intelligent road that provides clean renewable energy using power from the sun while providing safer driving conditions，along with power and data delivery"巷道是一個(gè)智能化的道路，太陽能提供清潔的可再生能源利用來自太陽的力量，提供更安全駕駛條件下，隨著電力和數(shù)據(jù)傳輸；可知太陽能道路不可用于天然氣動(dòng)力車；故選B．
75．B．主旨大意題．通讀全文，可知文章主要講了工程師們建立太陽能巷道的一個(gè)設(shè)想，他們希望能在不就得了將來實(shí)現(xiàn)幫助世人；因此最佳標(biāo)題為太陽能的未來的智能道路；故選B．

點(diǎn)評 考察學(xué)生的細(xì)節(jié)理解和推理判斷能力，做細(xì)節(jié)理解題時(shí)一定要找到文章中的原句，和題干進(jìn)行比較，再做出正確的選擇．在做推理判斷題不要以個(gè)人的主觀想象代替文章的事實(shí)，要根據(jù)文章事實(shí)進(jìn)行合乎邏輯的推理判斷．

2．Today，we complete our story about the influential English writer William Shakespeare．He wrote plays and poems during the late fifteenth and early sixteenth centuries，which remain very popular today．
During earlier times，people would probably have learned several ancient Roman and Greek plays．It was not unusual for writers to produce more current versions of these works．For example，in Shakespeare's play"The Comedy of Errors"，Shakespeare borrowed certain details from the ancient Roman writer Plautus．For his play"Macbeth"，Shakespeare most likely used a work on Scottish history by Raphael Holinshed for information．Shakespeare might have borrowed from other writers，but the intensity（強(qiáng)度）of his imagination and language made the plays his own．While many plays by other writers of his time have been forgotten，Shakespeare and his art live on．
Shakespeare was also influenced by the world around him．He described the sights and sounds of London in his plays．His works include observations about political struggles，the fear of diseases，and the popular language of the city's tradesmen．Shakespeare's knowledge of the English countryside is also clear．His works include descriptions of deep forests，local flowers，and the ancient popular traditions of rural people．
It would be impossible to list all of the ways in which Shakespeare's works have influenced the world culture．But the first and greatest example would be his great influence on the English language．During his time，the English language was changing．Many new words from other languages were being added．Shakespeare used his sharp mind and poetic inventiveness to create hundreds of new words and rework old ones．For example，he created the noun forms of"critic"，"mountaineer"and"eyeball"．Many common expressions in English come from his plays，including"pomp and circumstance（裝腔作勢）"from"Othello"，"full circle（繞圈子地）"from"King Lear"，etc．The list of cultural creations influenced by Shakespeare is almost endless．From paintings to television to music and dance，Shakespeare was well represented．Shakespeare's plays have been translated into every major language in the world．
Shakespeare became a wellknown writer during a golden age of theater．His years of hard work paid off．
54．From the passage，we can see thatB．
A．Shakespeare was hardworking when he was a student
B．many of Shakespeare's works were influenced by earlier writings
C．the experience of living in London had no effect on Shakespeare's works
D．Shakespeare became rich later because of the popularity of his works
55．Why could Shakespeare's works survive his time？C
A．Because there were so few people writing plays in his time．
B．Because he produced too many works that nobody else could do．
C．Because his works were rich in imagination and language．
D．Because he was a rich and influential person of his time．
56．Shakespeare's greatest influence should be onC．
A．paintings      B．television      C．the English language      D．music and dance
57．The passage is mainly aboutD．
A．a(chǎn)n introduction to Shakespeare's life and his works
B．the main features and styles of Shakespeare's plays
C．Shakespeare's greatest influence on the world culture．
D．how culture influenced Shakespeare and he influenced culture．

19．Jack Andraka from Maryland won the grand prize at the 2012 Intel International Science and Engineering Fair．It is the largest high school science competition in the world．The Maryland teenager is the youngest winner of the $ 75，000 prize．He was chosen from among 1，500 students in 70 countries．
Jack Andraka invented a test for pancreatic cancer（胰腺癌）．He started to learn it after losing a close family friend to the disease．"I went on the Internet and I found that 85 percent of all pancreatic cancers are found late，when someone has less than a 2% chance of survival，"he says，"and I was thinking，'That's not right．We should be able to do something．'"He found that early discovery is important to increasing the chances of surviving the disease．
The Maryland teenager asked to work in a laboratory at Johns Hopkins University in Baltimore and was allowed．There he developed a simple paper test，which can recognize the disease in a single drop of blood．His test has proven correct 90% of the time．It also is 100 times more sensitive than other tests．"It costs 3 cents per test，and then it takes only 5 minutes to run，"he said．
Jack's success wouldn't have been possible without Anirban Maitra，a professor at Johns Hopkins．He was the only person among the 200 researchers Jack wrote to who showed interest in his project．"I was very surprised that this was a 15-year-old boy who was writing this．I wanted to meet this clever young man and see what he wanted to talk about and so I called him over for an interview．"
Jack worked in Professor Maitra's laboratory，completing his project in 7 months．The government has given the Maryland teenager patent rights to the pancreatic caner test．He is now talking with companies about developing the test into a simple product．
