Question

【题目】 in the adult ceremony，the senior students feel they are shouldering heavier responsibilities now.

A. Swear B. Sworn

C. Having sworn D. To have sworn

Answer 1

【答案】C

【解析】试题分析：考查非谓语动词。句意：经过成人仪式的宣誓，这些高中生觉得现在他们肩负着更重的责任。两个句子共用一个主语the senior students，并且“宣誓”这个动作发生在feel之前，故用having done形式。
