B.    with its cargo of 750000 gallons leaking into the ocean, and it polluted

C.    and its cargo of 750000 gallons leaked into the ocean, polluting

D.    while it leaked its cargo of 750000 gallons into the ocean and caused the pollution of

E.     so that its cargo of 750000 gallons leaked into the ocean, and they were polluting.

答案是C，这是为什么呢?我选的是A

请教！

这句话最好的表达是体现因果关系

因为 an oil barge ran aground off and its cargo of 750000 gallons leaking .... 所以 polluting the beaches

C就是这个意思。

A的while体现不出这个含义，反而表达的是 两个动作是同时发生的。

这道题要更据逻辑选择最合理的表达 方式。

明白咯，谢谢alohabrian

应该是leaking 导致
