OG48求教!

48. 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

A 和C有什么区别吗?

有， on account of one's doing ， 不能直接用doing .

楼主应该多问一个为什么： because of , on account of 等词语后面直接接doing没有用从句或者后面接名词短语好；哪怕在别的语法书或者表达上出现；

大部分SC没有绝对，只有相对；
