Question

The old man,____abrosd for twenty years,is on the拜托了各位 谢谢

The old man,____abrosd for twenty years,is on the way back to his motherland. A.to work B.working C.to have worked D having worked 请详细讲解每一个选项

Answer 1

有个单词是不是打错了abrosd ---abroad D having worked 分词的完成时表示该动作发生在谓语动词的动作之前。 to work 将来 /主动，很明显这里已经在国外工作了20年了 不定式做定语一般放在所修饰的词的后面，所以这里用v-ing working 表示该动作和谓语动词的动作同时发生或者在它的后面发生。 所以我认为选择D having worked
