很多人都分不清楚，all和both的用法上区别在哪?下面总结一下：
all指三者或三者以上的人或物,用来代替或修饰可数名词;也可用来代替或修饰不可数名词。
both指两个人或物,用来代替或修饰可数名词。all和both在句子中作主语、宾语、表语、定语等。如：I know all of the four British students in their school.(他们学校里四个英国学生我全认识) / --Would you like this one or that one? –Both.(你要这个还是那个?两个都要。)
all和both既可以修饰名词(all/both+(the)+名词),也可以独立使用,采用“all/both + of the +名词(复数)的形式,其中的of 可以省略。如：All (of) (the) boys are naughty.(是男孩都调皮)
