问题：我选的B，选的时候对c中的polluting的发起者存在疑问，polluting前免加逗号或者不加对polluting的发起者有影响吗？会不会让人觉得polluting的发起者是ocean啊？ 查看答疑

问题：C中的污染不知道是and前的还是and后的，意思不清楚，虽然it有点重复，但意思比较清楚 查看答疑

问题：A选项，录音上说泄露的发起者不能是船，还说船怎么能泄漏油？感觉不是很理解 查看答疑

问题：金老师，语法课上说causing的发出者是主语，老师这里我有点不明白，现在分词在句首时，现在分词的动作发出者应该找主句的主语，类似此题这种情况，现在分词不在句首，在逗号后面，它的主语也应该是主句的主语吗 查看答疑

问题：c中and 后面的 leaked into 是状语部分的动词还是谓语的动词？谓语不应该用was leaked 吗？ and后状语能跟主句并列？ 查看答疑
