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.

no matter+疑问代词只能用于让步状语从句 疑问代词+ever既可以引导让步状语从句也可以引导名词性从句
如：whoever leaves the room last ought to turn off the light.
