1．The Bangladeshi-American，Salman Khan was born in 1976to a poor immigrant family．He knew clearly（33）that/how education could give people power and change their lives for the better：Khan went to a public high school （34）where"a few classmates were fresh out of jail"，as he told The New York Times，but he got into the Massachusetts Institute of Technology．
He got Bachelor of Science degrees in mathematics，electrical engineering and computer science，and also got a Master of Business Administration degree from Harvard Business School．Khan then worked as a successful hedge-fund analyst （對沖基金分析師）．
It all began in 2004（35）when Khan began tutoring his cousins who were having difficulty with math．To make it easier to communicate with them，he decided to put the lessons online as a series of videos．His cousins quickly found that they preferred seeing Khan online．
"（36）Having （have） a video lesson that they could pause and repeat made it easier to learn"commented Wired magazine．without tiring their tutor．
He started to realize that the videos could help a lot more people and never grow old．He then quit his job，made more than 4，800videos teaching math of all grades，put them online，and started Khan Academy in 2006．
"My ideas about teaching were straightforward and deeply personal．I wanted to teach in the way I wished that I（37）had been taught（teach）．I hoped to show the joy of learning，the excitement of understanding things about the universe．I wanted to pass along to students not only the logic but the beauty of math and science，"he wrote in his book The One World Schoolhouse：Education Reimagined．
The academy has become so popular across the world（38）that celebrities and businesspeople are starting to offer donations，including Microsoft founder Bill Gates．He has donated more than 9million （about 57million yuan） to the academy organization，reported Forbes．
However，Khan doesn't want to make money from it．"My goal is to make learning faster for students of all ages．（39）With so little effort on my own part，I can give a large number of people power for all time．I can't think of a（40）better （good） use of my time，"Khan said in his TED talk．
分析 本文主要講述Salman Khan創(chuàng)辦網(wǎng)上視頻課程的故事．他出生于一個貧窮的家庭，獲得了商業(yè)管理碩士學位．在幫助他的老表學習數(shù)學時，將一些視頻課程放到網(wǎng)上，發(fā)現(xiàn)很受歡迎，便辭退了工作，在2006開辦了Khan學院，幫助更多的學生學習數(shù)學和科學．
解答 33．that/how 考查連詞．know后接的賓語從句education could give people power and change their lives for the better是完整的，用連詞that；或表示方式，用連詞how．
34．where 考查定語從句．分析句子結構可知這是一個定語從句，先行詞a public high school在從句中作地點狀語，用關系副詞where．
35．when 考查定語從句． 分析句子結構可知這是一個定語從句，先行詞2004在從句中作時間狀語，用關系副詞when．
36．Having 考查動名詞．分析句子結構，句中缺少主語，用動名詞短語having a video lesson that they could pause and repeat作主語．
37．had been taught 考查虛擬語氣．根據(jù)語境，wish后接賓語從句表示與過去事實相反，用過去完成時，且I與teach之間是動賓關系，用過去完成時的被動語態(tài)．
38．that 考查固定句型．so…that…意為"如此/這么…以致于…"，句型中的so是副詞，常常用來修飾形容詞或副詞，常用句型為：主語+謂語+so+adj．/adv．+that從句．
39．With 考查with復合結構．此處是"with+名詞+介詞短語"復合結構作狀語．
40．better 考查形容詞比較級．根據(jù)句意：我不能想到更好地使用我的時間．用形容詞比較級better．
