He was so lazy that he had all of his washing ______.

A. to do B. to be done C. doing D. done
球答案加解析

Answer 1

选D。 have sth done/get sth done的结构。 done是过去分词，过去分词一般都是有被动的含义。理解成“让sth被（别人）做”，翻译好一点就是“让(某人)做某事”.比如，I need to have my cell phone repaired. “我需要让我的手机被修好”，翻译成通顺一点的中文就是“我得找人来修好我的手机”。
所以这句话的意思是“他太懒了，所以他让所有要洗的东西被（别人）洗” 翻译成通顺一点的中文，就是“他太懒了，所以他所有要洗的东西都找人来帮他洗”

这个解释应该还可以吧，相信你在任何参考书上都找不到如此具体的解析，除非是老师手把手的讲。（当然得是比较一流的老师，呵呵）
