本题D选项my和the都是限定词，用来修饰children所以他们两个只能有一个存在即去掉其中一个都是对的both后可直接跟名词，所以 a对的如果名词前有限定词修饰的话，就必须用 Both of both 可以单独使用,直接跟名词，或者动词we both like the film. we like both the pop music and classical music. both of 后接名词或者代词,但是名词前必须有限定词the 等谓语动词用复数 both of us like the film Both of the students go to school on foot.
