Question

4．Each year there is an increasing number of cars on roads and streets as millions of new cars and trucks are produced．One out of every six Americans works at putting together the parts of cars，driving trucks，building roads or filling cars and trucks with gas．（31）F
Most Americans would find it hard to imagine what life would look like without cars．（32）C The polluted air becomes poisonous and dangerous to health．
（33）DThat's what several of the large car factories have been trying to do．But to build a clean car is easier said than done．Progress in this field has been slow．
Another way is to take the place of the car engine by something else．（34）G Many makers believe that it will take years to develop a practical model that pleases man．
To prevent the world from being polluted by cars，we'll have to make some changes in the way many of us live．Americans，for example，have to cut down on the number of their total cars．They are encouraged to travel and go to work by bicycle．Bicycling is thought to help keep the air clean．But this change does not come easily．A large number of workers may find themselves without jobs if a car factory closes down．（35）A
Although cars have led us to a better life，they have also brought us new problems．

A．Thus the problem of air pollution would become less important than that of unemployment．
B．Americans know cars very well．
C．However，some have realized the serious problems of the air pollution that is caused by cars．
D．One way to get rid of the polluted air is to build a car that does not pollute．
E．However，the number of vehicles（車輛） has continued to increase in recent years．
F．Americans won't live without cars！
G．Inventors are now working on steam car as well as electric cars．

Answer 1

分析 美國(guó)人的生活和汽車息息相關(guān)，但由汽車導(dǎo)致的大氣污染問(wèn)題也很嚴(yán)重．針對(duì)這一問(wèn)題，本文討論了一些解決方法例如生產(chǎn)使用清潔能源的汽車，或者以自行車代替汽車等．

解答 31-35 FCDGA
31 F 根據(jù)前文One out of every six Americans works at putting together the parts of cars，driving trucks，building roads or filling cars and trucks with gas可知美國(guó)人的生活與汽車息息相關(guān)，而F選項(xiàng)Americans won't live without cars!"美國(guó)人離開(kāi)了汽車簡(jiǎn)直活不下去"正是對(duì)這一現(xiàn)象的一個(gè)總結(jié)，也與下文Most Americans would find it hard to imagine what life would look like without cars相關(guān)聯(lián)．故選F．
32 C 分析語(yǔ)境可知此處前文說(shuō)明大多數(shù)美國(guó)人對(duì)汽車的依賴，而后文The polluted air becomes poisonous and dangerous to health提到的是大氣污染．瀏覽選項(xiàng)發(fā)現(xiàn)C選項(xiàng)However，some have realized the serious problems of the air pollution that is caused by cars在語(yǔ)境上起到了承上啟下的作用．而且C選項(xiàng)中some和前文中的most Americans形成對(duì)比，however不僅表示了兩者的對(duì)比，還轉(zhuǎn)換了話題．故選C．
33 D 分析后文That's what several of the large car factories have been trying to do．But to build a clean car is easier said than done可知大的汽車工廠一直在努力做的是使用生產(chǎn)清潔無(wú)污染能源的汽車．由此推知that指代的內(nèi)容是build a clean car．瀏覽選項(xiàng)發(fā)現(xiàn)D選項(xiàng)One way to get rid of the polluted air is to build a car that does not pollute中的build a car that does not pollute與之對(duì)應(yīng)，符合語(yǔ)境．而且D選項(xiàng)One way to get rid of the polluted air is to build a car that does not pollute中的one way與第四段的段首Another way is to take the place of the car engine by something else中的another way對(duì)應(yīng)．故選D．
34  G根據(jù)前文Another way is to take the place of the car engine by something else可知解決汽車污染大氣問(wèn)題的另一個(gè)解決方法是用別的東西代替汽車能源．而G選項(xiàng)Inventors are now working on steam cars as well as electric cars中steam cars、electric cars都屬于清潔無(wú)污染能源的汽車，符合前文語(yǔ)境．故選G．
35 A 分析前文But this change does not come easily．A large number of workers may find themselves without jobs if a car factory closes down可知美國(guó)鼓勵(lì)人們放棄汽車，以自行車代步的可行性不大．因?yàn)槿绻�一個(gè)汽車工廠倒閉，將會(huì)有許多工人失業(yè)．瀏覽選項(xiàng)發(fā)現(xiàn)A選項(xiàng) Thus the problem of air pollution would become less important than that of unemployment中將環(huán)境污染問(wèn)題the problem of air pollution與工人失業(yè)問(wèn)題the problem of unemployment進(jìn)行比較，符合語(yǔ)境．故選A．

點(diǎn)評(píng) 注意段落間的關(guān)系
由于英語(yǔ)的句段之間經(jīng)常會(huì)運(yùn)用關(guān)聯(lián)詞表示銜接和過(guò)渡，使文章邏輯更清楚和連貫，因此文章中和選項(xiàng)中表示各種邏輯關(guān)系的路標(biāo)性信號(hào)詞在選擇答案時(shí)都是很重要的線索．典型的關(guān)聯(lián)詞有很多，例如and，also，as well as，neither nor，either or，not only…but also，on one hand…on the other hand等．這些連詞可以表現(xiàn)句子與句子之間的關(guān)系，通過(guò)不同的連詞考生可以推知句子與句子之間不同的關(guān)系．句子之間的關(guān)系可以根據(jù)關(guān)聯(lián)詞判斷，但將這些關(guān)系放大到段落之間，很多考生就難以察覺(jué)．
在做題過(guò)程中，考生不僅要關(guān)注語(yǔ)句之間的關(guān)系，還應(yīng)注意段落之間的關(guān)系．本文的第38小題就是這樣一個(gè)例子．考生可以分析后文得出that指代的內(nèi)容為build a clean car．D選項(xiàng)One way to get rid of the polluted air is to build a car that does not pollute中的build a car that does not pollute與之對(duì)應(yīng)，由此考生可以選擇出正確答案．但如果考生能夠注意到第三段和第四段之間的并列關(guān)系，就可以根據(jù)第四段的段首句Another way is to take the place of the car engine by something else中的another way is to…推測(cè)出第三段的段首句的格式為one way is to…那么考生就可以直接選擇D選項(xiàng)，從而加快做題速度．
