二、作定语的-ed分词
-ed分词可以作前置定语也可以作后置定语,作后置定语时相当于一个定语从句。
1.-ed分词可以作前置定语,此时,分词与名词之间有两种语义关系:一种是分词表示主动意义;一种是分词表示被动意义。如:
He is a retired worker.
他是一个退休工人。
This is a newly-developed device.
这是一个新开发的工具。
2.-ed分词作后置定语时,其功能相当于一个定语从句。如:
She likes to drink cold boiled water.
他喜欢喝凉白开。
They were inspecting the houses damaged by the storm.
他们正在视察被暴风雨毁坏的房屋。
1) Commercial banks make most of their income from ______ interest on loans and investments in stocks and bonds.
[A] earn
[B] earned
[C] to earn
[D] was earned
解析:B为正确答案。空档前是一完整的句子,在没有连词的情况下,不能填充A和D;根据题意,“利息”是“通过…(被)挣来的”,有被动之意,所以选B。
2) On his return from his _______ college, he found the house.
[A] deserting
[B] deserted
[C] desert
[D] to be deserted
解析:B为正确答案。此句的意思是“房子”被“遗弃,没人住”,是被动的意义,而A和C都不符合这一点。D是动词不定式,一般表示将来或具体动作,所以D也不对。
3) 改错:The age [A] of a geological sample can be estimated [B] from the ratio of radioactive to nonradioactive carbon present [C] in the object is examined [D].
解析:D错。应去掉多余的“is”,使-ED分词“examined”作后置定语修饰“object”。C处并没有错。“present”是形容词,它与后面的成分构成形容词短语修饰限定前面的“the ratio...carbon”。
