1. dress

　?。畚螅軲y father bought a new dress for himself yesterday.

　　［误］The mother dressed the clothes on her child.

　?。壅軹he mother dressed her child.

　?。畚觯載ress作及物动词当穿衣服讲时，其后不能接衣服而只能接人，如：The boy is still too young to dress himself. 但作为一种穿着打扮的状态时，则多用其过去分词作形容词，如：He is not dressed in his new suit.或She is dressed in red. 词组dress up是过节日时应服装整齐，如：They dressed up for the holiday.

　　dress, have on, put on, wear

　　要区别这几个动词需分清是表示动作的动词还是表示状态的动词。表示状态的动词是have on和wear, 如：He has on a white coat. He was wearing heavy shoes. 而put on则表示穿衣的动作，如：Put on your coat, it is cold outside.而dress既可以作状态又可以作动作，作动作讲时其后面接人而不能接衣服，作穿着状态时则多用dressed的形式。如：I saw a lady dressed in red. I saw a girl dressing herself.

　　［正］I have been studying English for three days.

　　4. each

　?。畚螅軪very of them has his habit.

　?。壅軼e 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.

　?。壅軼hat on earth do you mean

　?。畚觯輔n 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.

　　7. easy
