句中no matter what引导让步状语从句，no matter"无论......；不管......"，后接what/who/which/where/when/how等。

　　No matter what happens，we'll never lose hope.

　　No matter who wants to visit the museum，he must ask our teacher for permission.

翻译：____________________________________________________

①no matter＋what/who/which/where/when/how也可替换成what/who/which/where/when/how＋ever的形式。

②"no matter＋疑问词"只能引导让步状语从句，而whatever，whichever，whoever等除了引导状语从句外，还可引导名词性从句。

　　You can come whenever/no matter when it is convenient to you.

翻译：____________________________________________________

　　Whatever is worth doing should be done well.

翻译：____________________________________________________

【提示】　whatever和whichever的意义区别常会成为命题的依据，我们需要明确的是，whatever意为"无论什么，任何......的东西"，通常是没有范围限定的，而whichever意为"无论哪一个"，通常是有限定范围的。
