虛擬語氣錯誤
虛擬語氣的使用錯誤在綜合改錯題中主要表現為主句和從句的語氣不協調。
例如： We suggest that Henry is told about his condition as soon as possible.
句中動詞suggest之後的從句應用虛擬語氣，故“is”應改為“be”或“should be”。類似的動詞還有propose/ insist/order等等。
非謂語動詞的錯用。
例如：
①Play football not only makes me grow up…
Play football是動詞，不能做主語，應將其改為Playing football。
②I want to thank you again for have me in your home for the summer holidays.
介詞後面應跟名詞，所以for have應改為for having。
③I’d like to your pen friend, and get to know more about your country.
would like to後面應加to do，your pen friend是名詞短語，不能直接放在would like to後面，所以應改為to be your pen friend。
形容詞副詞混用。
常出現需形容詞的.地方用了副詞或需要用副詞的地方用了形容詞。這類錯誤主要考較不常見的形容詞、副詞的比較級形式。一般來講，考生不難掌握。
例如：
① It’s terrible hot here.
Terrible是形容詞，不能修飾形容詞，應將其改為terribly。
② Culture is essentially to our humanness.
Essentially—essential。Culture is後面應該有一個表語，但是essentially是副詞不能做表語，因此改成essential。
介詞錯誤。
主要是介詞的多餘或缺失、錯用。這一部分需要平時多多積累來弄清常用介詞的搭配。
例如：
① In an addition, he still went to see a movie.
In addition是固定搭配，所以應將In an addition改為In addition。
② This has probably been the case in quite a while.
In--for Has been是現在完成時的表達方式。因此與之相對應的時間狀語就應該是for a quite a while，for表示持續的—段時間。
