17．Many people know the names Alexander Graham Bell and Thomas Edison．However，most people don't know the name of the man who invented the television，Philo Farnsworth．
      Philo Farnsworth was born in 1906 and grew up on a potato farm．As a boy，he loved to learn about science，and he read a lot of science books．When he was only thirteen years old，he drew a picture of a machine that could send pictures as radio sends sounds．He got the idea from the way the potatoes were planted in the field．The potatoes grew in long lines，side by side．This made a shape in Philo's mind．This shape helped Philo think of a way to send the TV picture onto a piece of glass．But he was poor，so Philo could not try to make his idea into a machine at that time．
      Later，Philo worked at many different jobs．He worked with trees．He worked on broken radios．He worked on trains．He also worked as a street cleaner．At last，two rich men heard about his idea for television，and they gave him the money to make it．On September 7th，1927，they watched Philo test the machine hebuilt．When Philo turned on the machine，a small line could be seen on the glass．Philo said，"There you have it，electric television．"
     Later，a big company，RCA，said they had made the first television．Philo had to spend a lot of money on lawyers to fight them．Finally，he won．Then，World War Two started in 1939．During the war，Philo spent a lot of money helping the US army instead ofbuilding up his television company．After the war，other bigger，richer companies started making televisions．In the end，Philo had to sell his company．

分析 本文主要講述了電視機的發(fā)明者---Philo Farnsworth的相關(guān)情況．

解答 66：C    寫作意圖題：文章第一段提到Alexander Graham Bell and Thomas Edison 兩個人實際是想引出Philo Farnsworth．這個話題．選C
67：C   細節(jié)題：從第二段的句子：He got the idea from the way the potatoes were planted in the field．可知，他是從土豆地里想到的主意，答案是 C
68：B   數(shù)字計算題：從第二段的句子Philo Farnsworth was born in 1906 知道他是1906年出生的，還有On September 7th，1927，they watched Philo test the machine he built．說明發(fā)明第一臺電視是在他21歲時．選B
69：C猜詞題：從后面的句子After the war，other bigger，richer companies started making televisions．說明built up是"增強"的意思．選C

點評 社會文化類是英語閱讀中常見的題材，掌握該類的英語閱讀理解技巧十分重要．主旨大意題在歷史文化類文章中是常考的題型．解答這類試題的英語閱讀理解技巧：1．讀首句抓大意．文化教育類閱讀理解文章多采用說明文、議論文體裁，而這類文章大都采用文章段落的中心，即主題句在文章開頭．因此，要尋找這類文章的主旨大意就需要研究文章的首句． 2．讀尾句抓大意．有時這類文章的主題句安排在文章的結(jié)尾，作為對全篇的總結(jié)． 3．讀首段抓大意．有些文章或段落的開頭和結(jié)尾部分都有主題句．這種結(jié)構(gòu)是為了突出主題思想而使用兩次點題的寫作方法．這兩個主題句在句子結(jié)構(gòu)和用詞上有所不同，而且在內(nèi)容上前句和后句也不重復． 4．從段落中抓大意．有些文章或段落的主題句在文章中，這種文章或段落往往以一句話或幾句話引出要表達的主題，在主題句出現(xiàn)后，再舉例子陳述細節(jié)或繼續(xù)論證． 5．歸納要點抓大意．有些文章或段落無明顯的主題句，只是暗示性地體現(xiàn)主題．這就要求同學們在閱讀過程中根據(jù)文中所敘述的事實或線索來概括總結(jié)主旨大意．

8．The number of young people in Africa is growing．So is the number of older people in Asia．The share of the elderly-those aged sixty-five plus in total population-as well as relative to the working age population is steadily increasing across Asia．
Japan has the world's oldest population.30% of Japanese are older adults．In recent weeks，Japanese political leaders have been asked how they plan to care for the growing number of older adults．By 2030，the number of older adults in Singapore will rise 200% from current levels．This year，the government in Singapore released a song dealing with a population issue..It urges young people to produce more children to help end a drop in fertility．The song is fun，but the problem is serious．The government is offering to pay up to three thousand two hundred fifty dollars for each of the first two children．It will pay almost five thousand dollars for the third and fourth children．In Thailand，the population older than 65rose to just over 7% in 2010from 3.6% in 1975．Thailand's family planning efforts have led to much-smaller families．In the 1960s，mothers had an average of 5to 6children．Now，that number has fallen to 1.5．That is well below the number of births needed to keep the population count unchanged．
Steep population aging means an increased demand for income security，health and long-term care，which creates huge socio-economic and cultural challenges that will need to be addressed with a strong political and appropriate social policy．Other changes include reforming，social security systems in developed countries．Another is creating social safety systems in developing nations where traditional family support systems are disappearing．The most cost-effective and humane thing a society can do for its older citizens is to invest in their health so they can remain active．

47．What is the main point the author makes in the text？B
A．The population growth in Asia．
B．The population aging in Asia．
C．Population and economy in Asia．

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．
