時態語態和語氣的使用錯誤
1. 時態錯誤。 主要是指在一個句子中，出現不同的時態，從而造成時態不一致，如： He can't remember what he once knows.
2. 語態錯誤。 在 cet6 綜合改錯題中最常見的語態錯誤是被動語態被誤用為主動語態。不及物動詞不能帶賓語，因而也就沒有被動語態。如： She was very angry at not telling the truth when she listened to the account.
3. 虛擬語態錯誤。 此類使用錯誤在綜合改錯題中主要表現為主語和從句的語氣不協調，如： We strongly suggest that Henry is told about his physical condition as soon as possible. 句中動詞 suggest 之後的從句應用虛擬語氣，故「 is 」應該 「 be 」或「 should be 」。類似的動詞還有 demand ， insist ， order 等等。
例 1 These newly wedded couples usually came here and meet 1.__________
together to hold parties.
由於前面的時態已經限制為過去時，而且 came 和 meet 是並列結構，兩者時態應該保持一致，因此應該將 meet 改為 met ，或者將 came 改為 come ，具體情況依據上下文的語境時態而定。
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.__________
本句中三個平行成分 which products to emphasize now ， which to develop for the future 和 which to be dropped 結構模式應該一致，均採用不定式主動語態，因而 to be dropped 應改為 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.
根據句子意思可知，此處的 liquid 不可能為動作的發生者，顯然此處應該是被動語態，故應該將 has 改為 is 或者在 has 後加 been 均可，意思是指「已經安全獲得的液體」。
例 4 Did they gone there yesterday, they would have discovered 1.__________
the truth.
根據句子意思可知，這句話是說如果他們昨天去了就會發現事實真相，然而他們並未去，此處是虛擬語氣，因此應該使用虛擬語氣的格式，將 Did 改為 Had .

答案解析：working→work.此句總體上講述的是這些小家庭獨立的掠影，而後半句解釋到這些小家庭的成員生活在一起、工作在一起的情景，應該用一般現在時，和live保持一致。 are→were. are→were. allow前加be.「be allowed to do sth.」是「被允許作……」的意思。 offered前加be.「offer」是及物動詞，後面應該接雙賓語結構，即「offer sb. sth.」而在該句中缺少成分而只有賓語補主語，應該將其改為被動語態，即「be offered sth.」
6. offered→offers.
7. taken前加have.
8. plan→planned.
9. kept→keep.
10. carry→carrying.
