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。（以上內容由美加莫清崴老師提供） ※ 引述《comicduo (Jimmy)》之銘言： : Unlike crested wheatgrass, an alien species from Siberia that forms only : shallow roots and produces tall above-ground shoots,[ native North : American grasses develop an extensive root system, allowing for : greater enrichment of the soil, but do not grow to be very ] tall. : (A) native North American grasses develop an extensive root system, allowing : for greater enrichment of the soil, but do not grow to be very : (B) native North American grasses develop an extensive root system, which : allows for their greater : enrichment of the soil, but without growing to be that : (C) the root system of native North American grasses is extensive, allowing : for greater enrichment of the soil, but they do not grow to be very : (D) the root system of native North American grasses is more extensive, : allowing for the greater enrichment of the soil, but these grasses do not grow to be very : (E) the extensiveness of the root system of native North American grasses : allows for their greater enrichment of the soil, but they do not grow to be : that : 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) -- ※ 發信站: 批踢踢實業坊(ptt.cc) ◆ From: 114.36.53.31
