GMAT語法while與but的區別分析介紹

　　GMAT語法測驗中，有時刻會湧現句意轉變的題，而致使句意轉變的緣故原由很大部門是由於銜接詞轉變，而考平生時對這些銜接詞的應用不懂得，致使斷定失誤，本日就給眾人先容下GMAT語法while與but的差別考核。

　　while的用法：

　　while引誘的從句：

　　意思是“當…時”，放句首或句中

　　意思是“遷移轉變比較contrast”時，多放在句中，也能夠放在句首。

　　while表現比較觀點的時刻，兩個事物如果同時產生。

　　意思是“固然、只管”(妥協)時，多放在句首。(=although)

　　表現前提,意為"只要",其意思和用法相稱於as long as。while可處於句首,也可處於句中。

　　真題1：

　　After several years of rapid growth, the healthy care company became one of the largest health care providers in the metropolitan area, while it then proved unable to handle the increase in business, falling months behind in its payment to doctors and hospitals.

　　A. while it then proved unable to handle the increase in business, falling months behind in its payment to

　　B. while it then proved unable to handle the increase in business and fell months behind in its payment to

　　C. but then it proved unable to handle the increase in business, falling months behind in its paying

　　D. but then proving unable to handle the increase in business, falling months behind in paying

　　E. but then proved unable to handle the increase in business, falling months behind in paying

　　翻譯：

　　幾年的飛速成長以後，康健照顧護士公司成為這個大都會最大的康健公司之一，但是以後卻不克不及很好地處置快速發展的奇跡，好幾個月沒有付大夫和全部病院人為

　　句式：

　　the company became one of the largest providers, but then proved unable to handle sth., falling months behind in panying

　　思緒：

　　考核遷移轉變

　　選項：

　　A. 即使表現遷移轉變比較，while也有"at the same time"的寄義在內裏，與then抵觸，並讓句意釀成了the health care company expanding and falling是同時產生的，然則現實上應當是先became largest，然後再fell;

　　B. 同B，而且fell和proved構成並列，邏輯紕謬;

　　C. 前面的it過剩，可以省略(effctiveness);in its paying，使得paying從動詞釀成了動名詞，不簡練，prep.+one's+doing每每是不簡練的。paying這個行動便是the health care company履行的，以是不消加之its;

　　D. but要銜接兩個句子或曰語，proving轉變了邏輯;

　　E. 準確。

　　真題2:

　　Building large new hospitals in the bistate area would constitute a wasteful use of resources, on the basis of avoidance of duplicated facilities alone.

　　A. on the basis of avoidance of duplicated facilities alone

　　B. on the grounds of avoiding duplicated facilities alone

　　C. solely in that duplicated facilities should be avoided

　　D. while the duplication of facilities should be avoided

　　E. if only because the duplication of facilities should be avoided

　　翻譯：

　　假如僅僅由於是這些舉措措施的反復應當被防止，那末在B這個地區建又大又新的病院將會是一種資本的糟蹋。

　　句式：

　　Building X would constitute a wasteful use of Y, (modifier).

　　思緒：

　　經由過程意思來懂得句子意思;前面說了一件事，背面說明了一個緣故原由。

　　選項：

　　A. 'on the basis of x'這個短語中會默以為X已存在了,然則A沒有湧現題目，以是選取毛病;介詞兩個一樣平常會造成潤飾毛病;

　　B. avoiding duplicated facilities語義邏輯毛病，文章誇大的是防止反復而並不是防止工場;誇大重心產生變更;avoid的邏輯主語毛病;

　　C. avoiding duplicated facilities語義邏輯毛病，文章誇大的是防止反復而並不是防止工場;誇大重心產生變更;avoid的邏輯主語毛病

　　D. 一樣轉變句子意思，本來是經由過程一個潤飾身分解釋為何building是欠好的;然則WHILE卻湧現了遷移轉變的意思;

　　E. 準確。

　　真題3：

　　Industrialization and modern methods of insect control have improved the standard of living around the globe while at the same time they have introduced some 100,000 dangerous chemical pollutants, having gone virtually unregulated since they were developed more than 50 years ago.

　　A. while at the same time they have introduced some 100,000 dangerous chemical pollutants, having

　　B. while at the same time introducing some 100,000 dangerous chemical pollutants that have

　　C. while they have introduced some 100,000 dangerous chemical pollutants at the same time, which have

　　D. but introducing some 100,000 dangerous chemical pollutants at the same time that have

　　E. but at the same time introducing some 100,000 dangerous chemical pollutant, having

　　翻譯：

　　產業化的殺蟲辦法進步了人們的生存程度而於此同時這些辦法也引入了一些化學汙染物，這些化學汙染物沒有獲得有用的治理。

　　句式：

　　Industrialization and modern methods… have improved… while introducing…

　　思緒：

　　While和but的差別，一個可以加動名詞，一個弗成以;另有代詞指代的題目。

　　選項：

　　A. Having潤飾主語IM methods，邏輯語義毛病，應當潤飾汙染物;全部句子中的兩個代詞they指代工具不同等，劃線部門they沒有指代工具，未劃線部門的they指代的是pollutants;

　　B. 準確;

　　C. "introduced 100,000 dangerous chemical pollutants at the same time" 表現的是這麽多化學物資被同時引入;然則邏輯語義只是誇大了汙染物被引入是一個甚麽樣的影響;全部句子中的兩個代詞they指代工具不同等，劃線部門they沒有指代工具，未劃線部門的they指代的是pollutants;

　　D. Introducing和have improved不屈行;but須要先後平行，while不須要;

　　E. having gone…分詞構造有作隨同狀語潤飾have introduced的歧義，而不是作pollutants的定語。
