有这样一题:
The oil ________ (discharge) into the sea seriously harmed a lot of birds and animals.
老师提供的答案是:which discharged。但如果只填discharged对吗?或者填which was discharged可以吗?因为discharged可用作及物和不及物动词啊!
付老师:
我同意你的看法,在没有给出具体语境的情况下,三种填法应该都是对的。用作不及物动词,discharge相当于flow,用which discharged作定语,句子的主语可以理解为“流进大海的油”。如果用作及物动词,discharge相当于send out,用其过去分词或应用其被动语态的定语从句作定语,主语就可以理解为“被排放进大海的油”。显然,后者更突出人为因素。以下是《剑桥高级学习词典》中的两个例句(其中之一便是原题目):
Large amounts of dangerous waste are discharged daily by the factory.
The oil which discharged into the sea seriously harmed a lot of birds and animals.
