题目分析:
本题中介词on account of和because of都是“因为”的意思,没有区别。
选项分析:
A选项:on account of是介词,身后的 living at great depths—2,500 to 3,000 feet down是动名词短语。在语法上,动名词在句中是没有逻辑主语的,如果想给动名词加逻辑主语,必须用所有格的形式,例如:
James’s playing cards
因此,本选项中的live是没有逻辑主语的。在整句的逻辑上,居住在2500英尺深的必须是crab,否则The golden crab of the Gulf of Mexico has not been fished commercially in great numbers不能和living at great depths—2,500 to 3,000 feet down之间形成因果关系(on account of)。
B选项:代词their是复数代词,在句中没有合理的指代对象。crab是单数名词。
C选项:Correct. 本选项在语法和逻辑上均是正确的。
D选项:本选项错误同(A)。
E选项:being无法表达出前后两者的因果关系,且它也不是连词。另外,代词they的指代错误同选项(B)
on account of/because of + n.名词(√)
on account of/because of + 动名词(×)
