The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-2,500 to 3,000 feet down.
25. The golden crab of the Gulf of Mexico has not been fished commercially in great numbers, primarily on account of living at great depths-2,500 to 3,000 feet down.
A. on account of living B. on account of their living C. because it lives D because of living E. being they live
请大家指教解题思路:
B & E 错,理解。 The crab 所以不选they, their.
跟据GMAT所述,我自己会先排除C. it 距离the crab 太远,易犯指代不清。通常it 指最近的那个名词,变成指the Gulf of Mexico了。明显有问题。
另外,不明白A & D 为什么错?语法上貌似没问题。但OG 解释说,On account of living is awkward and wordy; because of living is not the correct idiom
