GMAT語法題如何復(fù)習(xí)

　　GMAT語法，是一種見仁見智的事物。GMAT語法題又是考生們頗為頭疼的煩惱之一?？赡苡腥藭?huì)問，我們中國(guó)學(xué)生語法功底都挺雄厚的，怎么還怕GMAT語法題呢?其實(shí)，GMAT語法題所要考查的能力，遠(yuǎn)非記住幾個(gè)語法常態(tài)那么簡(jiǎn)單，GMAT語法題是需要考生仔細(xì)琢磨和研究的。GMAT如何復(fù)習(xí)?GMAT語法題又該如何搞定?本文這就為您揭開謎題。

　　1. Acid rain and snow result from the chemical reactions between industrial emissions of sulfur dioxide and nitrogen oxideswith atmospheric water vapor to produce highly corrosive sulfuric and nitric acids.

　　(A)with atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

　　(B)with atmospheric water vapor producing highly corrosive sulfuric and nitric acids

　　(C)and atmospheric water vapor which has produced highly corrosive sulfuric and nitric acids

　　(D)and atmospheric water vapor which have produced sulfuric and nitric acids which are highly corrosive

　　(E)and atmospheric water vapor to produce highly corrosive sulfuric and nitric acids

　　這道題目的考查對(duì)象為between…and…這一常見的固定搭配，用來連接兩個(gè)名詞或名詞短語，本題對(duì)考生的干擾主要在于sulfur dioxide和nitrogen oxides中間已經(jīng)出現(xiàn)了一個(gè)and，有些考生就想到GMAT語法要求句子簡(jiǎn)明，那么連用and肯定不合適，首先將C，D和E排除掉了。但是如果用with，整句話邏輯關(guān)系不通，這個(gè)錯(cuò)誤當(dāng)然要比用詞重復(fù)嚴(yán)重得多，相比之下還是選擇使語意合乎邏輯的選項(xiàng)，正確答案為E。我們不選C和D的理由并不是由于句子不簡(jiǎn)潔，而是其邏輯關(guān)系有誤。

　　2. A majority of the international journalists surveyed view nuclear power stations as unsafe at present butthat they will，or could，be made sufficiently safe in the future.

　　(A)that they will，or could,

　　(B)that they would，or could,

　　(C)they will be or could,

　　(D)think that they will be or could

　　(E)think the power stations would or could

　　題干中的but表轉(zhuǎn)折關(guān)系，在對(duì)選項(xiàng)進(jìn)行比較時(shí)A，B，C比較容易吸引考生眼球，因?yàn)樗鼈兣c劃線句相似，D和E憑空多出個(gè)think，讓人感覺難以接受，但是如果僅僅以這個(gè)理由進(jìn)行排除顯然是證據(jù)不足的。我們應(yīng)該先分析原句結(jié)構(gòu)，抓住主線，該句屬于平行結(jié)構(gòu)形式，D和E中的think與view在意思上形成對(duì)應(yīng)，所以我們不應(yīng)對(duì)這兩個(gè)答案帶有任何偏見，而應(yīng)一視同仁。根據(jù)GMAT語法原則，不能隨意省略成分，否則句意就會(huì)出現(xiàn)ambiguity。比較五個(gè)選項(xiàng)，只有D的句意表達(dá)最完整。而為什么要使用think一詞我們大可不必去追究，這只是無關(guān)痛癢的小問題。

　　3.Unlike the acid smoke of cigarettes, pipe tobacco, cured by age-old methods, yields an alkaline smoketoo irritating to be drawn into the lungs.

　　(A) Unlike the acid smoke of cigarettes, pipe tobacco, cured by age-old methods, yields an alkaline smoke

　　(B) Unlike the acid smoke of cigarettes, pipe tobacco is cured by age-old methods, yielding an alkaline smoke

　　(C)Unlike cigarette tobacco, which yields an acid smoke, pipe tobacco, cured by age-old methods, yields an alkaline smoke

　　(E) The alkaline smoke of pipe tobacco differs from cigarettes’ acid smoke in that it is cured by age-old methods and is

　　解答本題時(shí)首先排除的是D答案，因?yàn)閐iffer from不能用在句首。本題的正確答案為C，但是很多考生的目光都是在C上暫作停留就轉(zhuǎn)向其他選項(xiàng)了。原因是C中連用了兩個(gè)yield，這樣的句子毫無美感可言，缺乏變化?？墒乔f別忘記考慮到句子重心問題，其他幾個(gè)答案都是把句子重心搞錯(cuò)了，smoke和cigarette對(duì)應(yīng)有誤，這可是大禁忌，比起這個(gè)錯(cuò)誤來，用詞重復(fù)還算得了什么呢?

　　GMAT語法題的難度一方面來自題干，另一方面來自選項(xiàng)，因?yàn)槲覀円揽縂MAT語法題選項(xiàng)之間的差別來獲得信息、尋求提示，GMAT如何復(fù)習(xí)?首先要搞清楚GMAT語法題的特點(diǎn)——矮子里拔將軍，本文介紹的所謂GMAT語法全解的核心，就是需要我們善于運(yùn)用排除法，挑選出相對(duì)準(zhǔn)確而有效的那一個(gè)。
