★榜首的解題★：20.My brother had an accident while____how to ride a bicycle. (A)learned(B) was learning(C) had been learning (D) learningMy brother had an accident while____how to ride a bicycle. 上句原句是 My brother had an accident while he learned how to ride a bicycle. 看出來是減化後的句子，可見是考分詞構句，分詞構句的減化方法：❶主詞相同, 就省略主詞,。❷把動詞改成ing 變成分詞構句。就變成→ My brother had an accident while learning how to ride a bicycle.
