虚拟语气的使用错误在综合改错题中主要表现为主句和从句的语气不协调。

例如： We suggest that Henry is told about his condition as soon as possible.

句中动词suggest之后的从句应用虚拟语气，故“is”应改为“be”或“should be”。类似的动词还有propose/ insist/order等等。

非谓语动词的错用：

例如：

①Play football not only makes me grow up…

Play football是动词，不能做主语，应将其改为Playing football。

②I want to thank you again for have me in your home for the summer holidays.

介词后面应跟名词，所以for have应改为for having。

③I’d like to your pen friend, and get to know more about your country.

would like to后面应加to do，your pen friend是名词短语，不能直接放在would like to后面，所以应改为to be your pen friend。

形容词副词混用：

常出现需形容词的地方用了副词或需要用副词的地方用了形容词。这类错误主要考较不常见的形容词、副词的比较级形式。一般来讲，考生不难掌握。

例如：

① It’s terrible hot here.

Terrible是形容词，不能修饰形容词，应将其改为terribly。

② Culture is essentially to our humanness.

Essentially—essential。Culture is后面应该有一个表语，但是essentially是副词不能做表语，因此改成essential。

介词错误：

主要是介词的多余或缺失、错用。这一部分需要平时多多积累来弄清常用介词的搭配。

例如：

① In an addition, he still went to see a movie.

In addition是固定搭配，所以应将In an addition改为In addition。

② This has probably been the case in quite a while.

In--for　Has been是现在完成时的表达方式。因此与之相对应的时间状语就应该是for a quite a while，for表示持续的—段时间。
