选择题
(2013·齐鲁名校二模)Though the suspect refused to admit that he had stolen the precious diamond at first, he ________ and admitted everything when he was shown the videotape.
A．broke off
B．broke away
C．broke down
D．broke into
答案
答案：C
选C 考查动词短语辨析。句意：尽管犯罪嫌疑人一开始拒绝承认偷了这颗贵重的钻石，但当他看到监控录像时他精神崩溃并承认了一切。根据句意可知，应选break down“(健康、精神) 垮掉”。break off“中止，中断”；break away“强行逃脱”；break into“闯入”。
