        　　原文：If he had not broken his tooth, he would not be in hospital now.
        　　翻译：如果他没有把牙齿弄坏，现在就不在医院了。
        　　解析：本句需要注意，属于比较复杂的“虚拟条件句”——“错综时间条件句”，指带有虚拟条件状语从句的复合句里，主句和从句代表不同的时间。在这种虚拟条件句里，需要按不同的时间来调整动词形式。
        　　If he had not broken his tooth，条件句与过去事实相反，应用had+过去分词;
        　　he would not be in hospital now，主句与现在事实相反，应用should/would/could/might+动词不定式。
        　　另外，注意in hospital和in the hospital指代情况不同。in hospital一般指住院(因为生病，且不强调哪家医院)，而in the hospital则更倾向于表达人在医院里(不一定因为生病)。
