请问如何分别以-ever为后缀的词引导的是名词性从句还是状语从句？

名词性从句和定语从句中：what = the thing which；whatever = anything What you want has been sent here。 Whatever you want makes no difference to me。 类似的还有who= the person that whoever= anyone who状语从句中："no matter +疑问词" 或"疑问词+后缀ever" No matter what happened, he would not mind。 Whatever happened, he would not mind。 替换：no matter what = whatever no matter who = whoever no matter when = whenever no matter where = wherever no matter which = whichever no matter how = however注意：no matter 不能引导主语从句和宾语从句。 （错）No matter what you say is of no use now。 （对）Whatever you say is of no use now。 你现在说什么也没用了。(Whatever you say是主语从句) （错）Prisoners have to eat no matter what they're given, （对）Prisoners have to eat whatever they're given。 囚犯们只能给什么吃什么。再辨析：They eat whatever they can find。他们找到什么就吃什么。（现在不确定他们有没有找到东西可吃）They are eating what they have found。他们在吃他们找到的东西。（他们已经找到了可吃的东西）。

总得来说,特殊疑问词后面除了why 都可以加,比如:whatever, whoever, whichever, whomever,whenever, however, wherever.Whatever you say, I will do according to my own view.(状语从句）Whoever breaks the law will be punished.（主语从句）应该注意的是：－特殊疑问词＋ever＝ no matter＋特殊疑问词，但后者仅能用在状语从句中．比如：No matter who you are, you should obey the rules.The present will be given to whoever likes it.

当这些从句在句子中做主语,宾语或表语时,就是名词性从句;做状语时,就是状语从句. I can remember whatever you have told me.(whatever引导的从句做remember的宾语,所以是宾语从句)Whatever you say, I'll be able to remember it.(主句很完整,所以是让步状语从句)Whoever goes last should shut the door.(缺主语,所以是主语从句)Whoever goes last, you should accompany him.(主句很完整,是让步状语从句)
