就是不懂

each可以做形容词，也可以做代词。例句：each man likes the beer.
each of men likes beer.
every只能做形容词，不能做代词。例句：every woman likes shopping. 而 every of women likes shopping 是错误的。
each 指两个或两个以上中的一个；而every 指三个或三个以上中的一个。
each 在意义上注重个别，every 在意义上注重整体。例句：
each of us has his likes and dialikes. 我们各有各的好恶。
every one of us has the sme view of the problem.对这个问题，我们的看法相同。
