Question

She opened her eyes and was about to cry out ______ she heard her father urgently telling her to keep quiet.

A．when

B．while

C．before

D．after

Answer 1

A

試題分析：考查連詞用法。句意：她睜開眼睛，剛要哭，這時聽見爸爸急切地讓她保持安靜。四個選項都可用以引導時間狀語從句，when 和while 表示“當…時”，before“在…前”，after“在…后”， 此處是“be about to do sth when…”結構，表示“正要……這時……”。while 引導從句時一般用延續性動詞，因此最佳答案為A。
