2007年12月英語六級考試短文改錯沖刺訓(xùn)練(1)

　　本期重點： 平行結(jié)構(gòu)

　　平行結(jié)構(gòu)錯誤主要指在并列連接詞and前后語法結(jié)構(gòu)不對等、不平行。其它并列連詞還有but, as well as, or, or else, both … and, neither … nor, either … or, not only … but (also)等可連接兩個對等的詞和對等的結(jié)構(gòu)。

　　考點例析

　　1：Computeranalyzed marketing reports can help deciding

　　which products to emphasize now,which to develop for

　　the future,　and which to be dropped.�� ____________

　　解析：本句中三個平行成份which products to emphasize now, which to develop和which to be dropped結(jié)構(gòu)模式應(yīng)該一致，均采用不定式主動語態(tài)，因而to be dropped應(yīng)改為to drop。(注：在四六級考試中，短文改錯只能修改、刪除或添加一個單詞，不能同時改動兩個。本例題旨在反映平行結(jié)構(gòu)的語法性質(zhì)。)

　　例2：At the heart of the NEA survey is the belief that our

　　democratic System depends on leaders who can think

　　critically, analyze texts and writing clearly. ___________

　　解析：can后面有三個并列的謂語動詞，因此writing應(yīng)改成與think, analyze并列的動詞原形write。

　　例3：Atrophy is a decrease in size of a cell, organ, tissues, or other part of the body. _______

　　解析;：并列連詞or連接四項名詞結(jié)構(gòu)，其中cell 和organ皆為單數(shù)形式，故tissues應(yīng)改為單數(shù)tissue。
