Question

【題目】 ( work) abroad for twenty years, the old man is on the way back to his motherland.

Answer 1

【答案】Having worked
【解析】通過(guò)本文考查了學(xué)生對(duì)一些英語(yǔ)語(yǔ)法的理解和應(yīng)用。如固定搭配，形容詞副詞的區(qū)別，名詞的用法等。Having worked 考查非謂語(yǔ)動(dòng)詞。由for twenty years可知，該句需用現(xiàn)在完成時(shí)，the old man與work 之間是主謂關(guān)系，所以這里需用現(xiàn)在分詞。
