【题目】Hearing the war was , the crowd all burst into .
A.at the end, tears
B.at an end, crying
C.at an end, tears
D.in the end, citing

【答案】C
【解析】句意：听到战争结束了，人们都哭了。at an end，为固定搭配。“结束，终止，到头” in the end为固定搭配，“最后”burst into后面接名词,表示突然…起来；故burst into tears“突然哭起来”；burst out后面接doing的形式，“突然…起来”。burst into tears表示“突然哭了”，故选C。
