问题 Man has used metals for centuries in gradual increasing quantities, but it was not until the Industrial Revolution that they came to be employed in vast quantities.
选项 A、gradually increasing quantities
B、increased quantities gradually
C、gradual increased quantities
D、increasingly gradual quantities
答案 A
解析    (1)画线部分错误分析。
   题干中increasing为分词修饰中心名词quantities，而gradual应为副词形式gradually，用来修饰increasing。
   (2)选项分析。
   根据上述分析，修饰词前置，中心词quantities置于短语之末，因此B选项可以排除；根据句意，gradually作为副词修饰increasing，表示“持续增长”，可以排除D选项，而increased作定语时，表示“已经增长了的”，C选项可排除，故选项A正确。
   【知识拓展】句式拓展：It is／was not until…that…(强调时间)。
   e．g．It is not until the radiant energy falls upon matter that it becomes heat energy．
   直到辐射能落到物质上以后，它才能变成热能。
   It is not enough to wait patiently until enough people oppose slavery to outlaw it．
   只是耐心等待让足够多的人反对奴隶制，直至在法律上取缔它，这样做是不够的。
