英語中的混合條件句（mixed conditionals）或錯綜時間條件句指同一句話中包含兩種不同時態的句子，分別用來談論不同時間所發生的事情。混合條件句可以表達兩類情況：第一類用來描述一種與過去相反的情況所導致的現在可能發生的結果；第二類用來描述一種與真實情況相反從而導致的與過去相反的可能結果。

混合條件句通常由表示事與愿違的虛擬條件句（third conditional）和表現在或未來情況的虛擬條件句（second conditional）的相應成分組成。比如：If I hadn't graduated from university, I wouldn't be who I am now. 如果我大學沒畢業，就不會成為現在的自己。前半句使用了過去完成時，表示與過去相反的情況；后半句使用 “would (not) + 動詞原形” 的結構，表示現在有可能發生的結果。做八道題，看看你能否選出時態正確且句意通順的混合條件句。
