[析]each作句子主语时其谓语动词要用单数形式，如：Each of us wants to learn English well，但each作同位语时，则应以原名词的数为准。
[误]Every of us has to pass the exam.
[正]Each of us has to pass the exam.
[析]every只可作形容词，不可作代词，而each既可作形容词，又可作代词，在作形容词时each侧重强调个体，而every 则侧重于全体。
[误]Everyone of us should do housework two hours a day.
[正]Every one of us should do housework two hours a day.
[析]everyone不可与of结构相连接使用，而every one则可以这样用。
[误]I should read English everyday.
[正]I should read English every day.
[析]要注意的是every day是“每天”，而everyday则是形容词为“日常的”。如：everyday English日常英语，everyday life日常生活。
[误]There are trees on every sides of the street.
[正]There are trees on each side of the street.
[析]every用于三者或三者以上的每一个，而each用于二者或二者以上的每一个。因为街道只有两侧，所以只能用each而不能用every.
[误]All my parents are engineers.
[正]Both my parents are engineers.
