means是单数还是复数
请看下面的题目:
By all _______, you must try every _______ to help him.
A. mean, meanB. means, means
C. means, meanD. mean, means
【陷阱】误选C,认为第一空前有all修饰,故用means,而第二空前有every修饰,故用mean。
【分析】其实,means是一个单复数同形的名词,并且永远带有尾-s。换句话说,在表示“方式”、“方法”时,不存在mean这一形式(mean主要用作动词,表示“意思是”;也可用作名词,表示“中间”、“中庸”)。此题正确答案为C,by all means为习语,意为“一定”、“尽一切办法”。顺便说一句,means用作主语时,其谓语的数需根据句意来确定。比较(from www网址未加载):
All possible means have been tried. 所有可能的办法都已经试过了。
Every possible means has been tried. 每种可能的办法都已经试过了。
若句意不能明确地表明主语的单复数,其谓语则用单数或复数均可。如:
Is [Are] there any other means of getting more money? 还有其他什么办法可弄到更多钱吗?
