单选题
A. each B. every C. apart D. once
【正确答案】
A
【答案解析】[解析] 词义辨析题。every是形容词,each即可作形容词也可作代词和副词,once意为“一次”,apart意为“分离,分开的”。从句意看,排除C、D两项;从句子结构看,空格处应为副词,故A正确。 ·each和every都有“每一”的意思,但两者的用法差别如下: ①从数量上看each用来指两个或两个以上的对象中的一个,而every则是指三个或三个以上的对象中的一个。 ②从含义上看,当所修饰的对象是三者或三者以上时,each和every常常可以通用,但each侧重于个体,every侧重于整体。例如: Every teacher is here.=All the teachers are here.老师都在这里。(强调全体) Each student has a bike.每个同学都有自行车。(强调个体) ③从词性和语法功能上看,every只能作形容词使用;each除了作形容词外,还可作代词和副词(副词用法见19题空格所在句)。例如: In each/every room there is a bed.每个房间里都有一张床。 (each和every作定语常可通用) Each of us has a new pen.我们每个人都有一支新的钢笔。
