麻烦讲解一下need for 的用法.
例句：The malaria drugs needed for what is known as artemisinin-based combination therapy reached only three percent of African children in need.
那么麻烦分析一下这个句子的结构，特别是for what is known as artemisinin-based combination therapy
答
这里的need是非谓语动词表示被动,其实改为主动是sb.need the drugs for sth...所以need和for本身不存在搭配用法.
