【用法】1) 当each作det 时， 后跟单数可数名词; 其所限定的名词用作主语时， 其动词应按第三人称单数处理， 如：E～boy was given a book. (给了每个男孩子一本书。)但如果each用作adv放在作主语的复数名词或代词后面， 其动词仍按复数处理，如：The girls～have their lessons to do. (那些女孩都各有功课要做。) 2) each other (相互， 互相)只能用作动词或介词的宾语， 如：like/respect/influence～other (互相喜欢/ 尊重/影响); strike at/talk to/look after/care for/sit next to～other (互相击打/谈话/照料/照顾/挨着坐);

【辨异】 1) each作det时，与every 的意义在表面上非常接近， 但在内涵上each 强调(每一)个体， 而every则强调全体(都)， 表示全部或没有例外， 如： Each man had a try. (每个人都各试了一下。) Every man had a try. (人人都试了一下。) 2) each other与one another的区别见ANOTHER。
