英语中的特殊疑问词+ever是什么意思?跟原来有什么不同与作用?
1个回答

补充：“疑问词 + ever”是近年来高考英语的一个考查热点,在各版本的中学英语教材中出现频率较高,而且是学生理解和掌握的一个难点.从不同角度论述这方面内容的文章很多,本文试图别辟蹊径,简单明了地归纳讲解这一问题.“疑问词 + ever ”可分为两类,“疑问代词 + ever ”：whatever / whichever / whoever (宾格 whomever )和“疑问副词 + ever ”：wherever / whenever / however.不论是“疑问代词 + ever ”还是“疑问副词 + ever ”,其意义都是“不管 / 无论 + 该疑问词的本义”.1.“疑问代词 + ever”可引导两种类型的从句,即让步状语从句和名词性从句(主语从句、宾语从句).(1)引导让步状语从句.此时 whatever / whoever / whichever 分别等于“ no matter + what / who / which”.例如：Whatever happened,he wouldn't say a word.= No matter what happened,he wouldn't say a word.Whoever says so,it is wrong.= No matter who says so,it is wrong.Whichever dictionary you (may) take,you will have to pay at least 20 dollars.= No matter which dictionary you (may) take,you will have to pay at least 20 dollars.注意：这类从句中应用一般现在时表将来,从句中也常用情态动词 may / might .(2)引导名词性从句.例如：Whoever smokes here will be punished.(主语从句) Beggars will eat whatever they are given.(宾语从句) Whichever he likes will be given to him.(主语从句) You may invite whoever / whomever you like.(常用 whoever 代替 whomever) 此时它们都不能换成“ no matter + 疑问词”的形式,但 whoever 等于 anyone who,whatever 等于 anything that.2.“疑问副词 +ever ”：wherever / whenever / however 一般只能引导一种类型的从句,即让步状语从句,此时它们分别等于“ no matter + where / when / how ”.例如：Wherever he goes (may go).I'll follow him.= No matter where he goes (may go),I'll follow him.Whenever I wisited him,he was always busy working.= No matter when I visited him,he was always busy working.However late he is,his mother will wait for him to have dinner together.= No matter how late he is,his mother will wait for him to have dinner together.注意：当 however 用作连接副词时也可引导名词性从句,而 whenever/ wherever 则不能引导名词性从句.例如：I'll give you however much money you need.(宾语从句,此时 however 不能改成 no matter how ).3.另外,whatever / whichever / whoever 与 whenever / wherever / however 分别可相当于 what / which / who 与 when / where / how 的强调式,引起的特殊疑问句往往是简单句,与原疑问词的意思、用法完全相同,只是表达的语气更为强烈,翻译时可加上“到底；究竟”等.例如：What(ever) are you doing 你(到底)在干什么?Which(ever) do you want to buy 你(究竟)要买哪一个?Who(ever) told you such a foolish story?(究竟)是谁讲给你这么蠢的事?When(ever) can I enjoy a long vacation?(究竟)什么时候才能给我放个长假呢?Where(ever) did you leave your dictionary?你(究竟)把词典放哪儿了?How(ever) did you collect so much money?你(到底)是怎样筹到这么多钱的?
