1. 简介
在四级新题型考试中，改错题是作为完形填空题的置换题出现的，在实考试卷中只能是二者取其一。所以它在考试中所占分值比例与完形填空一样，也是10％。改错题通常选用一篇200词左右的短文，其中有10个语法结构和用词方面的错误，分布在除首句外的10行中。这些错误可能是因为用错了一个词或词形变化造成的，也可能是因为多用一个词或少用一个词造成的。用错的词可能是意义或形式容易混淆的词，可能是意义相反的词，也可能是造成语法错误或搭配错误的词；词形变化错误可能是词性、时态、语态、性、数、格等语法方面的错误。有的错误在同一短语或句子中一眼就能辨别，有的错误则必须在充分理解上下文的基础上才能识别。考生在答题前一定要认真阅读并理解全文，答题时，要参阅和琢磨上下文。
2. 题型分析
改错也是一项综合测试题型。虽然形式不同，但其测试重点与完形填空所覆盖的测试内容大致相同。在解答改错题时，应主要从以下几个方面进行观察和判断：
固定搭配――考查动词词组、介词词组、形容词词组、动宾词组等固定搭配的用法；
语法句法――考查单复数、虚拟语态、从句等语法现象；
语义逻辑――考查上下文的语义关系，常利用反义词来混淆视听；
关系连词――考查句子内部或句群之间的逻辑关系，例如因果关系、转折关系、递进或并列关系、总分关系等；
指代关系――考查人称代词、物主代词、反身代词与被指代的名词的对应关系；
词汇用法――与完形填空相比较而言，改错部分考查的对象除名词、动词、形容词和副词等实义词的用法外，也经常考查一些功能词的用法，如介词、连词等。
3. 解题技巧
1) 首先，通读全文，把握文章全貌，抓住文章主旨大意；
2) 然后，根据上述5类改错题中常见的出题点，按图索骥，对号入座。注意一时拿捏不准的题目可先跳过；
3) 最后，再通读一遍全文，做好扫尾工作，解决难题，复查做好的题。
