all既可以代指可数名词复数，表示“（三者或者三者以上）都”，做主语时，谓语动词用主语是复数时的形式，比如：All present were shocked by the news. 所有在场的人都被这个消息震惊了。
all也可以代指不可数名词，表示“一切”，比如：All is going well. 一切顺利。
all也可以做限定词，限定可数名词复数或者是不可数名词，比如：All roads lead to Rome. 条条大道通罗马。All work has been done.
另外有“all of+名词”结构。比如：All of the students like her. All of the milk is here.
此外not all表示部分否定，意思是“并非全都”，比如：Not all of them are well-behaved.
none可表示“（三者或三者以上）都不”，经常用于none of结构中，可以代指名词，但不做限定词。
none可以用来代指可数名词复数，做主语时，谓语动词用单数和复数都可以，比如：None of them are/is aware of the risk.
none也可以表示“一点也不”，用来代指不可数名词，做主语时，谓语动词用单数，比如：None of the money was given.
each可表示一定范围中的“每一个”，用来指代单数可数名词，做主语时，谓语用单数形式，比如：Each has his own opinion. 每个人都有自己的意见。
它也可以做限定词，后加可数名词单数，比如：Each student has been given their own email address. （his or her听起来有点正式，现在普遍使用their）
each可以用在“each of+复数名词”结构里，比如：Each of the houses is different.
every只能做限定词，限定可数名词单数或抽象名词（reason, chance, right, confidence，success等），比如：Every day seems the same to her. I wish you every success.
every可以用在带有基数词和序数词的名词前，表示所涉及的间隔，翻译为“每隔……”，比如：every ten minutes 每十分钟；every third day 每隔两天。
用“every other+单数名词”可以表示“每隔一”，比如：every other week 每隔一周。
“every few+名词复数”翻译为“每隔几”， 比如：every few years 每隔几年。
every可以用在结构“every one of+名词复数”，比如：I bought a dozen eggs and every one of the eggs was bad.
each强调个体，every强调整体，比如：Each member is in favor of this proposal. Every member is in favor of this proposal.这两句话的侧重点就不同，前者可以翻译为：每个成员都赞成这项提案。后者可以翻译为：所有成员都赞成这项提案。
each可用于两者，every不能表示两者，比如：I have two sisters. Each (Every X) of them has a nice house.
each不可用于否定句，every可以用于否定句。比如：Not every (Not each X) student understood what he said.
