成人学位英语考试词汇学习:重点词组辨析(10)
1、each other, one another
这两个代词词组都作“互相”解,较多地在句子中充当宾语。each other一般只用于两个人或事物之间,one another则用于超过两个人或事物的场合。试比较:Wagner and Strauss often exchanged gifts with each other. (指两者。)The members in our group learned from one another. (指超过两者。)
又如:They sat down opposite to each other.他们相对而坐。They were not suited to each other.他们俩不合适。We have known one another since we were children.我们在小的时候就相互认识了。这两个词组的差别目前已不是很严格,有时可互相替换。
2、effective, efficient
这两个形容词虽然都可译成“有效的”,但含义有所不同。effective指某物有一种显著的,预期的效果或是取得了预期的效果,它还可表示“有战斗力的,得力的”的意思。如:
Her efforts to improve the school have been very effective.他为改善学校而做出的努力是卓有成效的。
This machine is an effective remedy for acid indigestion.这是一种治疗胃酸过多的良药。He has become an effective assistant.他已成为一名得力的助手。
efficient主要指某人办事效率高,不浪费时间和精力等,也可指机械设备“有效率的”。如:A good leader should be both competent and efficient.一名好领导应该精明能干,办事效率高。Our efficient new machines are much cheaper to run.我们所买的高效机器运转消耗要小得多。
