E
each
［误］ Every of them has his habit.
［正］ Each of them has his habit.
［析］ each可以作形容词，但也可作代词，而every只能作形容词。
［误］ The manager comes to America almost each month.
［正］ The manager comes to America almost every month.
［析］ each与every都作形容词讲时，都有"每个"之意，但有不同。each多指个体，而every则多指整体。如：We want every student to succeed. each不同来表达总体概念，所以不能与almost, nearly， likely等词连用。
［误］ We each has a book.
［正］ We each have a book.
［析］ each 作同位语时，其数应与其同位的名词相同，而each作主语时则应取其单数形式。
each other one another
each other与one another这两个词组的区别在很多语法书中强调each other是两者之间，而one another是多者之间，其实不然，如：All students must care for each other, must love and help each other. 事实上这两个词组是同义的，如果要讲有什么区别的话，当我们非常笼统地谈，而不特指什么人时，多用one another.
early
［误］ Could you come here more early?
［正］ Could you come here earlier?
［析］ 单音节和少数双音节副词的比较级和最高级要用er和est来作其结尾，如fast, soon, early, hard, long, near等。
earth
［误］ What on the earth do you mean?
［正］ What on earth do you mean?
［析］ on earth这一词组在句中为的是加强语气，其意为"究竟"、"到底"。而作为"地球"讲时则要加定冠词，如：How far is the earth from the moon. 而作为"泥土"讲时则为不可数名词，如：He filled the pot with earth and wanted to plant some flowers.
easy
［误］ You can easy imagine my surprise.
［正］ You can easily imagine my surprise.
［析］ easy只在有限的词组中被用作副词，如take it easy (不要紧张)，go easy, stand easy等。 例如：Easy come, easy go. (钱来的容易花的也快. )Easier said than done. (说的容易做着难。)
east
［误］ Japan is on the east of China.
［正］ Japan is to the east of China.
［析］ 在讲述地理位置时，有3个介词常用，它们是in, on和to, 其中in表示处于所表达的范围之内，如：Shanghai is in the east of China. on则表示双方接壤，如：North Korea is on the northeast of China. 而表示互不相接的两部分时则用to, 如：Taiwan is to the east of Fujian.
