50. School integration plans that involve busing between suburban and central-city areas have contributed, according to a recent study, to significant increases in housing integration, which, in turn, reduces any future need for busing.
(A) significant increases in housing integration, which, in turn, reduces
(B) significant integration increases in housing, which, in turn, reduces
(C) increase housing integration significantly, which, in turn, reduces
(D) increase housing integration significantly, in turn reducing
(E) significantly increase housing integration, which, in turn, reduce
significant/significantly
形容词副词的转义
significant 重要的 ；significantly 极大的
which 指代错误
正确答案A
在我看来，选现E的错误在于reduce，应该用reduces，可是新东方的石林说错误在于significantly，因为significant和significantly不仅词性不一样，词义也不一样。可我觉得其实两者的词义差不多啊。 另外，我想了解的是，如果将选项E改成reduces，是不是应该选E，因为选项A重的significant increases感觉应该加the，原因是increases之后有限定成分？请NN指教，谢谢！ |
