to somebody , a British person after shakes hands with the stranger . A. Introducing B. To introduce C. To be introduced D. On being introduced 答案是D項.很明顯.句中的空白處應 選用非謂語動詞的被動形式.如果將C項填入空白處.雖然這個不定式是被動形式.但不定式短語處于句首或是充當目的的狀語.或是充當含有虛擬意義的動名詞時.其意為:"一-就-".但如介詞on后帶被動態(tài)的動名詞.除上述意義外.還可表示:"在-的時候".D項答案的這個意義正符合上面句子的句意. 【查看更多】
