2.Flying cars may soon become a(61)reality(real).The rideshare service Uber has asked (62)an expert from NASA,the American space agency,(63)to help(help) the company develop cars that can fly.
Uber plans to use flying vehicles (64)inthe future to aoid traffic in and around cities.The company wants to use small,totally electric aircraft,(65)whichcould take off and land like a helicopter on top of parking garages.Uber said its flying vehicles would be much (66)quieter(quiet),cost less to operate and produce less pollution than helicopters.
One person in San Francisco(67)wrote(write) on Twitter,"I used to think flying cars was a ridiculous idea.(68)But I changed my mind this morning when I sat in heavy traffic."Another person added from Mumbai,India:"I'm reading about Uber(69)hiring(hire) a NASA engineer to build flying cars,while I'm stuck in traffic.There is hope."
The expert predicts there will be several early models of flying cars that can't fly (70)themselves(they) but with human pilots within one to three years.

分析 本文主要介紹一種新型汽車--飛行汽車.一家公司已要求從美國國家航空航天局來的專家?guī)椭鹃_發(fā)會飛的汽車.飛行汽車未來在城市里外避免交通阻塞.這種全電動飛機(jī)可以像直升機(jī)一樣起飛和降落.飛行汽車比直升機(jī)會更安靜,費(fèi)用少,產(chǎn)生更少的污染.專家預(yù)計(jì)會有一些早期的自己不能飛行汽車模型在1到3年內(nèi)出現(xiàn).

解答 61.reality 考查名詞.不定冠詞a后接名詞.
62.a(chǎn)n 考查冠詞.expert是可數(shù)名詞,單數(shù)形式前加不定冠詞a表示泛指,因其讀音以發(fā)元音開頭,用不定冠詞an.
63.to help 考查動詞不定式.a(chǎn)sk sb.to do sth.意為"讓某人做某事",動詞不定式作賓語補(bǔ)足語.
64.in 考查介詞.in the future意為"今后,將來",是固定搭配.
65.which 考查定語從句.分析句子結(jié)構(gòu)可知這是一個(gè)定語從句,先行詞electric aircraft在從句中作主語,用關(guān)系代詞which.
66.quieter 考查形容詞比較級.根據(jù)句中than,要用形容詞比較級.
67.wrote 考查動詞時(shí)態(tài).此處講述的是過去的事情,要用一般過去時(shí)態(tài).
68.But 考查連詞.前后兩個(gè)分句之間是轉(zhuǎn)折關(guān)系,用連詞but.
69.hiring 考查動名詞.a(chǎn)bout是介詞,后接動詞時(shí)用動名詞形式.
70.themselves 考查代詞.根據(jù)句意:專家預(yù)計(jì)會有一些早期的自己不能飛行汽車模型.用反身代詞themselves.

點(diǎn)評 在一篇200詞左右的語篇(短文或?qū)υ挘┲辛舫?0處空白,部分空白的后面給出單詞的基本形式,要求考生根據(jù)上下文填寫空白處所需的內(nèi)容或所提供單詞的正確形式,所填寫詞語不得多于3個(gè)單詞.要做好語法填空題,理解短文是解題的前提,扎實(shí)的詞匯、句型和語法知識是基礎(chǔ),英語國家的背景知識是必要的補(bǔ)充.考生須靈活運(yùn)用語法知識,如單詞詞性、單詞時(shí)態(tài)、名詞單復(fù)數(shù)、連接詞、代詞、冠詞等判斷各空白處應(yīng)填寫的內(nèi)容.答完后,還要通讀全文,核對所填單詞形式是否正確,是否符合語境.

10.At Blossom End Railroad Station,22-year-old Stanley Vine sat,waiting for his new employer.The surrounding green fields were so unlike the muddy landscape of war-torn France.After four horrible years as a solider in Europe,Stanley returned to England in February 1946.Armed now with some savings and with no possibility of finding a job in England,he answered a newspaper ad for farm help in Canada.Two months later he was on his way.
Stanley rose to his feet,trying to make the most of his five foot and four inches frame.The farmer,Alphonse Lapine,shook his head,"You're a skinny thing."On the way to his dairy farm,Alphonse explained that he had a wife and seven kids."Money is tight.You'll get up at dawn for milking,and then help me around the farm until evening milking time again.Ten dollars a week.Sundays off."Stanley nodded.He had never been on a farm before,but he took the job.
From the beginning Stanley was treated horribly by the whole family.They made fun of the way he dressed and talked.He could do nothing right.The humourless farmer frequently lost his temper,criticizing Stanley for the slightest mistake.The oldest son,13-year-old Armand,constantly played tricks on him.But Stanley never responded.
Stanley never became part of the Lapine family.After work,they ignored him.He spent his nights alone in a tiny bedroom.However,each evening before going to bed,he lovingly cared for the farmer's horses.On Saturday nights he hiked into the nearest town and wandered the streets or enjoyed a restaurant meal before returning to the farm.
Early one November morning Alphonse Lapine discovered that Stanley had disappeared,after working for only six months.The railway station master,when questioned later that week,said he had not seen him.In fact no one in the community ever heard of him again.That is,until one evening,almost 20 years later,when Armand opened an American sports magazine and came across a shocking headline,"Millionaire jockey,Stanley Vine,ex-British soldier and 5-time horse riding champion,began life in North America as a farmhand in Canada."

17.Cleverness is a gift while kindness is a choice.Gifts are easy-they're given after all.Choice can be hard.
I got the idea to start Amazon 16 years ago.I came across the fact that the Internet usage was growing at 2300percent per year.I'd never seen or heard of anything that grew that fast,and the idea of building all online bookstore with millions of titles was very exciting to me.I had just turned 30 years old,and I'd been married for a year.I told my wife MacKenzie that I wanted to quit my job and go to do this crazy thing that probably wouldn't work since most start-ups don't and I wasn't sure what to expect.MacKenzie told me I should go for it.As a young boy,I'd been a garage inventor.I'd always wanted to be all inventor,and she wanted me to follow my passion.
I was working at a financial firm in New York City with a bunch of very smart people and I had a brilliant boss that I much admired.I went to my boss and told him I wanted to start a company sellingbooks on the Internet.He took me on a long walk in Central Park,listened carefully to me,and finally said,"That sounds like a really good idea,but it would be an even better idea for someone who didn't already have a good job."That 1ogic made some sense to me,and he convinced me to think about it for 48hours before making a final decision.Seen in that light,it really was a difficult choice,but finally,I decided I had to give it a shot.I didn't think I'd regret trying and failing.And I suspected I would always be haunted by a decision to not try at all.
After much consideration,I took the less safe path to follow my passion,and I'm proud of that choice.For all of us,in the end,we are our choice.

21.What inspired the author with the idea of building an online bookstore?C
A.His dream of being an inventor.
B.The support of his wife.
C.The greatly increasing usage of the Internet.
D.Millions of exciting titles,
22.Which of the following is closest in meaning to the underlined sentence?A
A.The idea of not trying would keep coming to his mind and disturb him.
B.He would be very excited if he tried it out.
C.He would be always having a doubt if he didn't try.
D.The decision to not try the online bookstore would terrify him.
23. Which of the following would be the best title for the passage?D
A.Cleverness and Kindness
B.The Starting of Amazon
