no matter 意为“不论；无论”，与 what, who, when, where, which, how 等疑问词连用，引导让步状语从句。在从句中，常用一般现在时代替一般将来时，状语从句可放在主句前或主句后。
No matter what you say, I won't believe you. 无论你说什么，我都不会相信你。
You should respect the culture of the local places no matter where you are. 无论你在哪里，你都应该尊重当地的文化。
【拓展】“no matter+疑问词”结构相当于“疑问词+-ever”，如 no matter who=whoever。
