2011年2月GMAT考試邏輯真題(至2.22)(一)
    1 升橋問(wèn)題
    V1
    說(shuō)一個(gè)地方有那種為了過(guò)船可以升起來(lái)的橋,政府說(shuō)神馬要改建,讓更大噸位的船能夠通過(guò),然后還說(shuō)這樣還能夠環(huán)節(jié)汽車(chē)交通的問(wèn)題,問(wèn)削弱?
    我似乎做錯(cuò)了,有一個(gè)是升橋原來(lái)一個(gè)人來(lái)操作,現(xiàn)在三個(gè)人;還有一個(gè)是和船是否選擇走這個(gè)橋下面有關(guān),具體怎么說(shuō)的忘了。
    V2
    說(shuō)一個(gè)地方有那種為了過(guò)船可以升起來(lái)的橋,政府說(shuō)神馬要改建,讓更大噸位的船能夠通過(guò),然后還說(shuō)這樣還能夠環(huán)節(jié)汽車(chē)交通的問(wèn)題,問(wèn)削弱?
    參考選項(xiàng):升橋原來(lái)一個(gè)人來(lái)操作,現(xiàn)在三個(gè)人
    和船是否選擇走這個(gè)橋下面有關(guān)。 這個(gè)我記得的東西也就和原JJ上的一樣了。

    V1(710,v36) 說(shuō)一個(gè)地方要把原來(lái)的bridge拆掉,修一個(gè)新的。然后說(shuō)準(zhǔn)備把這個(gè)bridge修的比原來(lái)高,寬度比原來(lái)大。這樣在很多大船通過(guò)的時(shí)候就不用把橋吊起來(lái)(吊起來(lái)再放下這個(gè)過(guò)程要花一個(gè)小時(shí),期間橋上無(wú)法通車(chē))了。問(wèn)這個(gè)新橋?yàn)槭裁床荒芷鸬教岣呓煌ㄐ实淖饔谩?BR>    我選的答案是:因?yàn)闃蚪ǖ谋纫郧皩捔耍郧白卟贿^(guò)去的大船現(xiàn)在可以通過(guò)了,所以要把橋吊起來(lái)的情況有可能不會(huì)減少。
    V2(730,V38) 描述一種跨河大橋可以抬起來(lái)讓船過(guò)去。說(shuō)現(xiàn)在要把舊的移除建立個(gè)新橋。新橋可以減少因?yàn)樘蛟斐傻慕煌ǘ氯?,cause它更高更寬。問(wèn)削弱,a選項(xiàng)說(shuō)抬橋之前會(huì)停止交通一小時(shí)以待觀察之類(lèi)不是很確定
    V3(720,V36) 大橋通船那個(gè),選了C,有些otherwise怎么的船大橋改造了以后都去了
    V4(770,V44) 我選了會(huì)把更大的船吸引過(guò)來(lái)。想了好久。。。不確定
    2 咖啡因binding
    講大腦分泌一種神馬物質(zhì)能夠binding到一個(gè)神馬細(xì)胞之類(lèi)的東西上,binding多了人就會(huì)weakness,然后就想睡覺(jué),說(shuō)睡完了就binding少了,然后有人就說(shuō)什么binding是sleep的原因,問(wèn)支持?
    狗爸選的是咖啡能夠減少binding,從而起到不讓人想睡覺(jué)的目的

    GWD25-Q36
    The chemical adenosine is released by brain cells when those cells are active. Adenosine then binds to more and more sites on cells in certain areas of the brain, as the total amount released gradually increases during wakefulness. During sleep, the number of sites to which adenosine is bound decreases. Some researchers have hypothesized that it is the cumulative binding of adenosine to a large number of sites that causes the onset of sleep.
    Which of the following, if true, provides the most support for the researchers’ hypothesis?
    A. Even after long periods of sleep when adenosine is at its lowest concentration in the brain, the number of brain cells bound with adenosine remains very large.
    B. Caffeine, which has the effect of making people remain wakeful, is known to interfere with the binding of adenosine to sites on brain cells.
    C. Besides binding to sites in the brain, adenosine is known to be involved in biochemical reactions throughout the body.
    D. Some areas of the brain that are relatively inactive nonetheless release some adenosine.
    E. Stress resulting from a dangerous situation can preserve wakefulness even when brain levels of bound adenosine are high.
    b
    討論:
    背景:物質(zhì)A有一個(gè)特點(diǎn)B
    B多了→人睡覺(jué),睡完了→B少;
    結(jié)論:B是睡覺(jué)的原因
    分析:從現(xiàn)象推到一個(gè)結(jié)論
    既然要支持B是睡覺(jué)的原因,
    那么就要說(shuō)明: B多→人睡覺(jué)(題中出現(xiàn)),B少→人不睡覺(jué)(推理中缺失)
    答案:補(bǔ)足推理中缺失的一環(huán)
    是咖啡能夠減少binding,從而起到不讓人想睡覺(jué)的目的(疑似)
