本期重点： 平行结构

　　平行结构错误主要指在并列连接词and前后语法结构不对等、不平行。其它并列连词还有but, as well as, or, or else, both … and, neither … nor, either … or, not only … but (also)等可连接两个对等的词和对等的结构。

　　考点例析

　　1：Computeranalyzed marketing reports can help deciding

　　which products to emphasize now,which to develop for

　　the future,　and which to be 0dropped. ____________

　　解析：本句中三个平行成份which products to emphasize now, which to develop和which to be 0dropped结构模式应该一致，均采用不定式主动语态，因而to be 0dropped应改为to 0drop。(注：在四六级考试中，短文改错只能修改、删除或添加一个单词，不能同时改动两个。本例题旨在反映平行结构的语法性质。)

　　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后面有三个并列的谓语动词，因此writing应改成与think, analyze并列的动词原形write。

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

　　解析.：并列连词or连接四项名词结构，其中cell 和organ皆为单数形式，故tissues应改为单数tissue。

　　巩固与拓展

　　1.A majority of the reports received from people claiming

　　to have seen the lengendaiy Loch Ness monster have

　　proven to be mistakes, misconceptions, or tricked. ___________

　　2. Your semester grade is based not only on how well you
