“疑问词 + ever ”
“疑问词 + ever ”可分为两类:
“疑问代词 + ever ”： whatever / whichever / whoever （宾格 whomever ）
“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）。

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.

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 emperor是什么意思”。例如：
Wherever he goes 健康饮食的重要性（may go）. I'll follow him. = No matter where he goes （may go），I'll follow him.
Whenever I wisited him英语教学设计， he was always busy working. = No matter when I visited him， he was always busy working.

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 g7是什么意思）。
