十四、复合句——名词性从句
    一个句子起名词的作用，在句中做主语、宾语／介词宾语、表语、同位语，那么这个句子就是名词性从句。
    1.what/whatever的用法
    考生应把握：what是关系代词，它起着引导从句并在从句中担当一个成分这两个作用。如：
    They lost their way in the forest, and what made matters worse was that night began to fall.
    (what既引导主语从句又在从句中做主语)
    Water will continue to be what it is today—next in importance to oxygen.
    (what既引导表语从句又在从句中做表语)
