3.already,yet 两者均为“已经”之意,但already一般用于肯定句中,而yet一般用于否定句和疑问句中,如:The guests have already arrived.“客人已经到了。”Have the guests arrived yet?客人到了吗?The guests have not arrived yet.“客人还没有到。”不过,有时already也可用于疑问句中,但意义与yet不同,already用于疑问句中表示惊讶。试比较:
(1)Have you had lunch yet?
(2)Have you had your lunch already?
句(1)是询问信息,意为:“你吃过午饭了吗?”句(2)表示惊讶,意为“你已经吃过午饭了?”yet有时也用于肯定句中,但yet在肯定句中的意思与still相同,表示“仍然、还”,与already不同:Don't worry. There is yet/still time for you to prepare for the exam.“不用担心,你仍然有时间去准备参加考试。”The plans are yet to be approved. “计划尚待批准。”或者表示(未来某一时间)“迟早、早晚”:He may surprise us all yet.“他迟早会使我们大吃一惊的。”The enemy may win yet if we relax our efforts.“如果我们松劲,敌人还是迟早有可能获胜的。”
4.also,either,too,as well四者意思相同,但在用法上有不同。Also比较正式,用于肯定句或疑问句:Her sister has also gone to town. “她妹妹(或姐姐)也上城里去了。”Are you also a member of his association? “你也是这个协会的成员吗?”either只用于否定句,常出现于句尾:It won't do them any good,but it won't do them any harm either. 这事于他们无补也无损。Too和as well较口语化,常可互换使用:The dog is hungry,and thirsty too/as well. 这条狗既饿又渴。区别在于too只能用于肯定句,且在句中位置灵活:We,too,are going away.我们也要离开。As well 一般只用于句末:I understood from her that you undertook other important work as well.“我从她那里了解到你还干其他一些重要的活。”
