问题
选择题
It suddenly ______ to the detective that the professor was probably murdered by his own wife .
A．came about
B．took place
C．happened
D．occurred
答案
答案：D
题目分析：考查词组：这几个词都有发生的意思，但只有D. occurred可以用于It occurred to sb that…某人突然想起…，句意：侦探突然想起教授有可能被他自己的妻子谋杀了。选D。
点评：含义相同的词组，用法却大相径庭，要注意辨别，特别是一些动词的特殊用法要熟记，结合上下文做题。
