短文改错解题思路和检查原则：
1. 句中各部分的结构是否完整，特别是每个句子要有动词；
2. 谓语动词的时态、语态；
3. 非谓语动词的用法；
4. 名词的单、复数，格的使用是否正确；
5. 定冠词和不定冠词是否正确；
6. 代词的格和性的使用是否有误；
7. 定语从句中关系代词、关系副词是否准确无误；
8. 并列句中的并列连词、主从复合句中的从属连词用的是否得当。
短文改错解题四原则：
改动以最少为原则；虚词以添加或删除为原则；实词以改变词形为原则；以保持句子原意为原则。
短文改错解题步骤：
通读全文，掌握大意；整句分析，逐行推敲；反复通读，复查验证。
解题注意要点和能力培养：
1. 核对错项时，若的确有一时难以改出的地方，可以参考所改动项是否基本符合“1：1：8”的比例。即多一词1个，缺词1个，错词8个。
2. 核对改正的语法项目是否有重复。因为短文改错往往覆盖面广，一般不会出现重复考查某个语法点的现象。
3. 核对答题符号是否规范，位置是否准确，看看有无遗漏符号、忽略字母大小写和拼写等问题。
短文改错常见错误类型：
1. 谓语动词的错误是历年考试的重点和热点，常见动词错误类型有①一般现在时与一般过去时错用；②and前后动词时态不一致；③主谓不一致；④缺少动词，特别是be动词；⑤第三人称单数形式错用；⑥主动语态和被动语态错用。

One evening she told me that something happened when her parents was out. (was改为were，错误类型属于③)
There will an important game next month. (will后加be，错误类型属于④)
2. 名词的常见错误：单复数名词错用，可数名词与不可数名词错用。
I’ll get good marks in all my subject. (subject改为subjects)
Their word were a great encouragement to me. (word改为words)
Without enough knowledges, you can never teach well. (knowledges改为knowledge)
3. 冠词错误：误用a和an（根据单词的第一个音素来判定）；误用a/an和the（固定搭配，或泛指、特指；多冠词或少冠词）
We maybe one family and live under a same roof. (a改为the，the same是固定搭配)
As everyone knows, it’s famous mountain with all kinds of pants. (mountain是可数名词需用冠词，所以其前加a)
I hope you have pleasant journey. (journey是可数名词，故have后加a)
4. 形容词和副词错误：系动词（am/is/are/was/were/become/go）和感官性动词（smell/feel）后用形容词；词性的误用（形容词修饰名词；副词修饰动词和形容词）。
I’m sure we’ll have a wonderfully time together. (time是名词，要用形容词wonderful修饰)
My pronunciation was terribly. (was后用形容词，terribly改为terrible)
5. 代词错误：代词的主格和宾格（I/me; he/him; she/her; we/us; they/them）错误；反身代词（myself/yourself/himself/herself/themselves/ourselves）使用错误；代词的单数和复数使用错误；代词指代错误；多代词或少代词。

6. 非谓语动词的常见错误：不定式、动名词作主语、宾语时；and连接的不定式或动名词前后不一致；介词后用动名词形式作宾语；某些动词后要求接动名词或不定式。
Soon I began to enjoy talk to myself on paper. (enjoy后需接动名词，talk改为talking)

I particularly enjoyed driving through the countryside with you and saw the changing colors of the leaves on the trees. (and连接的动名词前后不一致，故saw改为seeing)
7. 介词错误：词组中的介词误用；介词意思理解偏差；介词的多用或少用。
There are too many people among my family. (among改为in，in my family为固定搭配)
I was so tired that I fell asleep at the moment my head touched the pillow. (去掉at，the moment引导从句)
