英语中的混合条件句（mixed conditionals）或错综时间条件句指同一句话中包含两种不同时态的句子，分别用来谈论不同时间所发生的事情。混合条件句可以表达两类情况：第一类用来描述一种与过去相反的情况所导致的现在可能发生的结果；第二类用来描述一种与真实情况相反从而导致的与过去相反的可能结果。

混合条件句通常由表示事与愿违的虚拟条件句（third conditional）和表现在或未来情况的虚拟条件句（second conditional）的相应成分组成。比如：If I hadn't graduated from university, I wouldn't be who I am now. 如果我大学没毕业，就不会成为现在的自己。前半句使用了过去完成时，表示与过去相反的情况；后半句使用 “would (not) + 动词原形” 的结构，表示现在有可能发生的结果。做八道题，看看你能否选出时态正确且句意通顺的混合条件句。
