The boy ________ by his father is Tom A beaten B beatingThe boy ________ by his father is Tom A beaten B beating选A还是B?为什么

问题描述:

The boy ________ by his father is Tom A beaten B beating
The boy ________ by his father is Tom
A beaten B beating
选A还是B?为什么

A
beaten by his father 是过去分词短语做后置定语修饰主语The boy的.
之所以用beaten 而不用beating,是因为beat 和主语The boy 是被动关系,即“挨其父亲打的那位男孩”(是汤姆)
语言点:
及物动词的过去分词表被动; 现在分词表主动
