短文填空作为很多学生短板，不论练习多少次，考试的时候仍然拿不到高分，今天我将短文改错的三步法分享给大家。
第一步 熟悉设错方式及命题特点1、设错方式：
多词：主要集中在冠词、介词、助动词、代词、不定式符号、固定搭配
少词：主要集中在冠词、介词、助动词、代词、不定式符号、语义重复、固定搭配
错词：主要集中在名词单复数、形容词/副词互变、冠词、介词、连词、代词、动词的市太和语态、非谓语动词、从句中的引导词
2、命题特点：“四不改”
1）单词拼写
2）大小写
3）语序错误
4）标点符号
第二步 掌握做题步骤1、通读全文，了解文章大意的同时数句子个数
2、逐词逐句分析
3、统计错误类型及个数
4、在有可能错误的句子中优先寻找可能的错误类型
第三步 把握命题规律通过对历届高考英语短文改错的深入研究和反复对比不难发现：短文改错的错误设计师有规律的。
1、多词
1）冠词→掌握零冠词的用法
2）介词→
①及物动词后接宾语时误加介词
eg:We're hoping to settle something that bothers to you.
The book I'm reading of talks about afternoon tea.
②在一些可直接用作状语的词或短语前误加介词in/on/for等
eg: We finally dropped Gina off at her parents' and made our way to home.
He left for Germany and finally settled in the United States.
It is easy to go to anywhere from the hotel.
It will be impossible for me to attend the meeting on this Sunday.
3）不定式符号→“一感，二听，三使，四看，五帮助”
4）be动词/助动词had→不用被动语态却用了
该用一般过去时用了过去完成时
5）人称代词多余→定从中关系词代替先行词充当成分时不需要代词指代
eg:The chance I grasped it has been a turning point in my life.
6）两个连接词不能并用引导一个从句
eg: Father asked me that what I would want as my birthday present.
7）误加语义重复的词：
two/both, all/whole, return/back,only/just等
eg: We returned back to the campsite to have supper.
She was only/just strange.
