despite意为“不管”“任凭”,相当于in spite of,后接名词、代词或动词,但语气比后者轻,不如后者常用.
如:
① He went out despite bad weather.他不管天气恶劣出发了.
② Despite the fogs we went out for a walk.尽管有雾,我们还是外出散步.
【注】despite后可接what引导的从句
如:① Despite what she says,I'll go.不管她怎么说,我也要去.② I would support him despite what he did.不管他做什么,我都支持他.
despite = in spite of,故不能再与of连用; in spite of / despite + 名词 = although + 从句
至于I've got to do sth其实是一种口头习惯用法，解释为:我必须/不得不要做某事了
