[解答]答案:C这个句子的主语是water,谓语是will continue to be,表语是what it is today,补语是next in importance to oxygen.what 在句子中表示"什么的样子"就像She is no longer what she was ten years ago.她不再是十年前的样子了.as 不能引导表语从句.
解析 C 关系代词what在这里引导一个名词性从句作to be的表语,同时what在表语从句中又为is的表语成分,这类语法结构还有,如:Show what you have written.(把你所写的给我们看看)和She is not what she was a few years ago.(她可不是几年前的她了)。其他选项均不能表示这种语法关系。
