“no matter+疑问词”和“疑问词+-ever”引导让步状语从句
1 “no matter+疑问词”引导让步状语从句
“no matter+疑问词”引导让步状语从句时,意为“不管……;无论……”,在句中起强调作用,从句既可以在主句之前,也可以在主句之后,通常用一般现在时表将来,有时从句中的动词可省略。
No matter how late it is, I'll wait for you.无论多晚,我都会等你。
No matter who you are, you must obey the rules.无论你是谁,都要遵守规则。
2 “疑问词+-ever”引导让步状语从句
“疑问词+-ever”引导让步状语从句,表示“不管;无论”,可与“no matter+疑问词”互换。
Believe in yourself, whatever/no matter what difficulties you are facing. 不管面临什么样的困难,都要相信自己。
However / No matter how painful the experience is, it is valuable. 不管那段经历多么痛苦,它都是宝贵的。
Whenever / No matter when you meet with trouble, you can turn to me for help. 不论你何时遇到麻烦,你都可以向我寻求帮助。
特别注意“疑问词+-ever”还可以引导名词性从句,如:whatever 意为“任何……的事物”,whoever 意为“……的任何人”, whichever 意为“(在某范围之内)……的那个人/物”等。此时不能与“no matter+疑问词”互换。
The gold medal will be awarded to whoever wins first place in the bicycle race.这枚金牌将会被颁发给在自行车比赛中获得第一名的任何一位选手。
Doing exercise makes you more energetic and ready to handle whatever is ahead of you for the day.锻炼会让你更加精力充沛,并准备好应付一天中你所面临的一切。
