Question

【題目】__________ I was talking on the phone, my mother arrived at home.

A. when B. until C. while D. although

Answer 1

【答案】C

【解析】試題分析：句意：我在打電話時，我媽媽到了家。when 和while都譯作“當(dāng)……的時候”。while強調(diào)主句謂語動詞表示的動作持續(xù)于while從句所指的整個時間內(nèi)；when可以指主句謂語動詞和從句謂語動詞所表示的動作同時或先后發(fā)生。until直到；although盡管。所以選C。
