一、时态语态和语气的使用错误
1. 时态错误。 主要是指在一个句子中，出现不同的时态，从而造成时态不一致，如： He can’t remember what he once knows. 2. 语态错误。 在 cet6 综合改错题中最常见的语态错误是被动语态被误用为主动语态。不及物动词不能带宾语，因而也就没有被动语态。如： She was very angry at not telling the truth when she listened to the account.
3. 虚拟语态错误。 此类使用错误在综合改错题中主要表现为主语和从句的语气不协调，如： We strongly suggest that Henry is told about his physical condition as soon as possible. 句中动词 suggest 之后的从句应用虚拟语气，故“ is ”应该 “ be ”或“ should be ”。类似的动词还有 demand ，insist ，order 等等。
例 1
These newly wedded couples usually came here and meet 1.__________
together to hold parties.
由于前面的时态已经限制为过去时，而且 came 和 meet 是并列结构，两者时态应该保持一致，因此应该将 meet 改为 met ，或者将 came 改为 come ，具体情况依据上下文的语境时态而定。
例 2
Computer analyzed marketing reports can help deciding
which products to emphasize now, which to develop
for the future, and which to be dropped. 1.__________
本句中三个平行成分 which products to emphasize now ， which to develop for the future 和 which to be dropped 结构模式应该一致，均采用不定式主动语态，因而 to be dropped 应改为 to drop 。
例 3
In the first place, the scientist at once put some
kind of material into the liquid which has already 1.__________
securely obtained.
根据句子意思可知，此处的 liquid 不可能为动作的发生者，显然此处应该是被动语态，故应该将 has 改为 is 或者在 has 后加 been 均可，意思是指“已经安全获得的液体”。
例 4
Did they gone there yesterday, they would have discovered 1.__________
the truth.
根据句子意思可知，这句话是说如果他们昨天去了就会发现事实真相，然而他们并未去，此处是虚拟语气，因此应该使用虚拟语气的格式，将 Did 改为 Had 。
