1、GMAT考試邏輯試題專項(xiàng)練習(xí)邏輯真題GMAT邏輯真題題目一:【邏輯】Twelve years ago and again five years ago, there wereextended periods when the Darfir Republic's currency, the pundra, wasweak: its value was unusually lowrelative to the world's most stable currencies. Both times a weak pundra made Darfir's manufactured

2、 products a bargainon world markets, and Darfir's exports were up substantially. Now some politicians are saying that, inorder to cause another similarly sized increase in exports, the governmentshould allow the pundra to become weak again.Which of the following, if true, provides the government

3、with the strongest grounds to doubt that the politicians' recommendation, iffollowed, will achieve its aim?(A) Several of the politicians now recommending that thepundra be allowed to become weak made that same recommendation before each ofthe last two periods of currency weakness.(B) After seve

4、ral decades of operating well below peakcapacity, Darfir's manufacturing sector is now operating at near-peak levels.(C) The economy of a country experiencing a rise inexports will become healthier only if the country's currency is strong or therise in exports is significant.(D) Those countr

5、ies whose manufactured products competewith Darfir's on the world market all currently have stable currencies.(E) A sharp improvement in the efficiency of Darfir'smanufacturing plants would make Darfir's products a bargain on world marketseven without any weakening of the pundra relative

6、 to other currencies.GMAT邏輯真題答案:【邏輯】參考答案: B思路：措施：the government should allowthe pundra to become weak again目的：in order to causeanother similarly sized increase in exports正確答案作用：1. 這個(gè)措施做了之后，目的也達(dá)不到;2. 一個(gè)會(huì)有一個(gè)“新因素”的介入來(lái)讓目的達(dá)不到;思考：Pundra becomes weak之后, export的量會(huì)因?yàn)橐粋€(gè)新因素的介入而不能增加。選項(xiàng)分析：A：與export的量會(huì)不會(huì)增加沒(méi)有關(guān)系;C：

7、此選項(xiàng)沒(méi)有說(shuō)出為什么export不能增加;D: 這個(gè)選項(xiàng)告訴我們: Darfir的競(jìng)爭(zhēng)國(guó)家全部都有穩(wěn)定的貨幣.有的同學(xué)會(huì)這么思考, 這說(shuō)明穩(wěn)定的貨幣很重要, 所以不能貶值pundra. 但是 “措施目的”文章的重點(diǎn)不是討論措施做不做, 而是討論 “措施做了之后, 目的會(huì)不會(huì)達(dá)到”;E: 即使不貶值pundra, Darfir的產(chǎn)品在世界市場(chǎng)上的議價(jià)能力也會(huì)提高.這個(gè)跟措施做了之后, 目的達(dá)不到,沒(méi)有關(guān)系.GMAT邏輯真題題目二:【邏輯】Many small roads do not have painted markings along theiredges. Clear edge marki

8、ngs would make iteasier for drivers to see upcoming curves and to judge the car's position onthe road, particularly when visibility is poor, and would therefore seem to bea useful contribution to road safety. However, after Greatwater County painted edge markings on all itsnarrow, winding roads,

9、 the annual accident rate along those roads actuallyincreased slightly.Which of the following, if true, most helps to explainthe increase in accident rate?(A) Greatwater County has an unusually high proportion ofnarrow, winding roads.(B) In bad weather it can be nearly as difficult fordrivers to see

10、 the road as it is at night.(C) Prior to the painting of the edge markings,Greatwater County's narrow, winding roads already had a somewhat higheraccident rate than other Greatwater County roads.(D) Many of the accidents on narrow, winding roadsinvolve a single vehicle veering off the road, rath

11、er than the collision of twovehicles.(E) After the markings were painted on the roads, manydrivers who had gone out of their way to avoid driving on those roads at nightno longer did so.GMAT邏輯真題答案:【邏輯】參考答案: E思路：A：謂語(yǔ)動(dòng)詞has, 沒(méi)有變化;B: 謂語(yǔ)動(dòng)詞canbe as difficult, 沒(méi)有變化;C: 時(shí)間是矛盾的;D: 謂語(yǔ)動(dòng)詞是involve, 較難判斷是否是變化的。許多事

12、故都是涉及到單個(gè)車翻下路，而不是兩車碰撞。那很有可能原來(lái)的路上的情況也是這樣的。所以不能解釋為什么事故率上升;E: no longer didso表明了一種變化，并且時(shí)間也符合(after.)。以前不在這條路上開(kāi)車的driver, 現(xiàn)在開(kāi)始在這條路上開(kāi)車,所以事故率有了上升。GMAT邏輯真題題目三:【邏輯】The population of Megacity, a sprawling metropolis inRemsland, has grown at a fairly steady rate for over a century. A hundred years ago, poor san

13、itation in thecity caused high mortality rates among the city's inhabitants, and what fueledthe population increase was immigration from rural villages. This immigration has continued and evenincreased. Moreover, in recent decades,city sanitation has improved enormously. Yet the city's popul

14、ation growth has not significantly accelerated.Which of the following, if true, most helps to explainwhy the city's population growth rate has not changed?(A) Mortality rates that were associated with poorsanitation in Megacity a hundred years ago were orders of magnitude higher thanare mortalit

15、y rates associated with vehicular traffic, which is currently amajor cause of death in the city.(B) For several decades, Megacity, as distinct from thecountryside, has had a steadily declining birth rate.(C) Cities smaller than Megacity have also experiencedsustained population growth.(D) The great majority of immigrants to Remsland settlein Megacity, at least initially.(E) Megacity has long offered better employment pro
