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．
Whatever happens，the professor believes Jack Andraka's name is one we will be hearing again over the next 10 to 20 years．

分析 文章主要講了一個(gè)叫Jack的男孩因?yàn)樽约喊l(fā)明的胰腺癌紙測(cè)而獲得了國(guó)際科學(xué)和工程獎(jiǎng)，并得到專利權(quán)．
解答 71．C 細(xì)節(jié)題．根據(jù)文章第二段He started to learn it after losing a close family friend to the disease，可得知Jack Andraka失去了一個(gè)朋友后，他決定研究胰腺癌，應(yīng)選擇C．
72 A 細(xì)節(jié)題．根據(jù)文章第三段There he developed a simple paper test，which can recognize the disease in a single drop of blood．His test has proved correct 90% of the time．It also is 100 times more sensitive（敏感的）than other tests，我們能發(fā)現(xiàn)這個(gè)paper test很成功，可得知應(yīng)選A
73 D 細(xì)節(jié)題 根據(jù)文章第四段Professor說的話：I was very surprised that this was a 15-year-old who was writing this，可知Maitra教授對(duì)他印象深刻，所以應(yīng)該選擇D
74．B 句意理解題．劃線句直譯就是接下來我們還會(huì)有機(jī)會(huì)聽到Jack的名字，即他會(huì)繼續(xù)在科學(xué)領(lǐng)域做貢獻(xiàn)，所以選B
75 A 標(biāo)題選擇題．文章主要講了Jack對(duì)于胰腺癌的研究，所以應(yīng)該選A
點(diǎn)評(píng) 本文是新聞?lì)}材，關(guān)注此類文章的特征：新聞的主題往往在第一段，最后常常有總結(jié)的段落．中間部分是對(duì)新聞細(xì)節(jié)的展開說明．所以在閱讀時(shí)要關(guān)注首段和尾端，把握主旨；解題時(shí)要關(guān)注中間的細(xì)節(jié)，根據(jù)題干和選項(xiàng)中的關(guān)鍵詞或句定位細(xì)節(jié)，比對(duì)選項(xiàng)和文章細(xì)節(jié)確定答案．
