141、no matter how hard it is
no matter how ...引导让步状语从句，意为“无论多么……”，how
后跟形容词或副词，相当于“however + adj./adv.”句式。
no matter意为“无论；不管”时，引导让步状语从句，常用于下列句型中：no matter what (who/when etc. )... 分别表示“无论何事”、“无论何人”、“无论何时”等，这个从句可以置于主句之前，也可以置于主句之后。no matter后接关系代词或关系副词引导的状语从句在句中作让步状语。
no matter what (who, which, where, when … )只能引导让步状语从句； whatever (whoever, whichever, whomever)既可引导让步状语从句，也可引导名词性从句。
no matter 引导的分句表达的是将来的含义，但形式上要用现在时。如：No matter who will come (改为：comes)；
no matter 引导的分句不能作宾语或主语。如：I’ll eat no matter what (改为：whatever) you give me；
whichever意为“无论哪个；无论哪些”；whatever意为“无论什么；凡是……的事物”。
whichever可以引导名词性从句或让步状语从句，which是个疑问词；用在疑问句中，或作关系代词，引导定语从句。
no matter which只能引导让步状语从句；而whichever可引导让步状语从句和名词从句。no matter which可以用whichever代替，但

结构中，这个结构前还可加所有格定语。类似的词有：delay, deny, fancy, imagine, excuse。
(2)、Do/ Would you mind doing something? 请你做某事是否介意吗？ mind 后的动作仍是主语you 的动作，表示说话人请求对方做某事，一般接动名词，而不用if 从句。
Would you mind one’s doing something? 某人做某事你介意吗？指说话人征求对方对自己做某事的意见。
这两个问句的答语，如表示允许、同意某人做某事用：No, I don’t mind/ No, go ahead/ No, please/ Of course not/ Not at all/ Certainly not. 如表示不允许用：I’m sorry, but it’s not allowed/ Yes, I do mind/ I’m afraid I can’t let you/ I’d rather you didn’t.
(3)、mind后的if 从句通常不用将来时，而用一般现在时或一般过去时。句前用do，从句通常用一般现在时；句前用would， if 从句通常用一般过去时；would 和从句中的一般过去时并不表示过去，而是说话人表示礼貌或委婉语气的需要，有时可用if you don’t mind于句尾。如： I’d like to ask you a few questions if you don’t mind = Would/ Do you mind if I asked/ ask you a few questions? 也可用：Would you be kind/ good enough to do something/ Would you be so kind as to do something? 表示请求，但语气较强。
(4)、只能接动名词作宾语的常用动词有：mind, enjoy, miss, escape, practise, suggest, give up, avoid, finish, insist on 等。巧记：memepsgafi妹妹不吃咖啡。
