GMAT留學考題解答[SC. ] PP2-56

 

本題可平衡對稱結構(parallelism)和比較要同類(illogical comparison) ,
在unlike A, B + Verb的句型中A與B要同類。
本題的A是指crested wheatgrass (大麥草),
B應指North American grasses而非root system,
所以不同類的C/D/E這三個選項都不選。
                                                                               
選項(A) native North America grasses develop... but do not grow...
                                     ________       ___________
                                       V1                V2
But是個對等連接詞,所連接的兩邊都要對等,
如原句中動詞(develop)連接動詞(do not grow)。
選項(B)所連接的兩邊不對等,
一邊是動詞develop,另一邊是介詞片語without growing...
解析如下:
native North American grasses develop...  but   without     grawing to be that
                              _______           _______     _________________
                                 V            prepositional     phrase

選項(A)的allowing修飾native North American grasses的可能性不大,
因兩者距離太遠,中間隔有動詞develop,
所以不會有歧義(ambiguity)上的問題。

: 答案是A 想請問B 不對的原因為何?
: 還有A的allowing 不會有修飾歧意嗎?
: (修飾an extensive root system 還有 native North American grass)
