解析
试题分析：考查if的非真实条件句：句意：如果我早些意识到危险，我就不会选择呆在临时避难所了。从句用过去完成时表示和过去相反的情况，主句用would have done表示过去的虚拟。选D。
点评：if的虚拟语气非常重要，简要概括如下：1、表示与现在事实相反的情况，从句：If主语+过去时(Be动词用were)；主句：主语+should/would/could/might+do： 2、表示与过去事实相反的情况，从句：If主语+had+done；主句：主语+should/would/could/might+have done 3、表示对将来情况的主观推测，从句：①if+主语+were to do②if+主语+should+do ③if+主语+did（动词过去式）/were ；主句：主语+should/would/could/might+do。 |
