题目

i know nothing about the young man___except that he is from America.
A,to defeat
B,defeating
C,defeated
D,be defeated
说明理由,

答案

C、那个被打败了的年轻人除了晓得他是美国人之外其他就一无所知了.
defeated
在这里过去分词做后置定语.表示已经被击败了的意思.
A不对是因为to defeat是及物动词,要有宾语,也就是the young man要有打败的对象.
B不对是因为defeating表示正在打败,打败谁呢?没宾语,再说defeat是瞬间动词,一般不能表示正在打败的意思.
D不对是因为be defeated这种省to不定式不能做定语,而这里是要一个定语.
