题目内容

There was a __________look on her face because a________ problem _________the little girl.
A．puzzled; puzzled; puzzledB．puzzling; puzzling; puzzled
C．puzzled; puzzling; puzzledD．puzzling; puzzled; puzzling
B

试题分析：考查puzzle用法。Puzzling令人困惑的(常用来形容事物)；puzzled感到困惑的（常用来形容人）；有些与人有关的事物也用puzzled修饰；第三空是谓语动词，因为本句是过去时，所以使用过去式puzzled。句意：在他的脸上有一个困惑的表情，因为一个让人困惑的问题困扰着这个小女孩。故B正确。
点评：Puzzling令人困惑的(常用来形容事物)；puzzled感到困惑的（常用来形容人）；有些与人有关的事物也用puzzled修饰；
