单选题 Susan{{U}} {{/U}}in doing the experiment again though she had failed many times.
  • A. resisted
  • B. insisted
  • C. assisted
  • D. persisted
【正确答案】 D
【答案解析】[解析] 形近词辨析 [解析] persist in doing sth.“坚持、执意做某事”。 [避错] resist和assist是及物动问，后面不跟介词：resist“抵抗，反抗；忍得住”；assist“帮助”。insist和persist为不及物动词，insist on doing sth.“主张做某事，坚持做某事”。
