Answer 1

C

试题分析：考查虚拟语气：句意：约翰一个人去了医院，如果他告诉我，我就会和他一起去了。主句用的是would have done表示和过去情况相反的虚拟语气，从句用had done。选D。
点评：虚拟语气在条件句中的用法是：虚拟条件句 与现在事实相反的假设，从句是If+主语+动词的过去式（动词be用were)，主句是：主语+should,would, might,could＋动词原形；与过去相反的假设从句用：If+主语+had +过去分词，主句是：主语＋should, would, might, could ＋have done；与将来相反的假设，从句用1、If+主语+动词过去式，主语＋should, would  do，2、If+主语+were to+ 动词原形，加主句3、If+主语+should +动词原形 ，加上主句的might, could＋动词 原形
