What he wants to get is whatever you have. 他想得到的是你所拥有的一切。

二、whatever引导的名词性从句whatever的意思是“whatever所……的一切事或东西”，可视为what的强调说法，其含义大致相当于anything that，whatever在从句中可用作主语、宾语、定语。如：Do whatever she tells you and you’ll have peace. 她叫你干什么你就干什么，那你就太平了。I don’t believe in letting children do whatever they like. 我不赞成让孩子为所欲为。
