问题 选择题
The sunlight is white and blinding,________hard­edged shadows on the ground.
A.being thrown   B.throwing
C.to throwD.to be thrown
答案

B

本题考查非谓语动词的用法。句意:太阳光白得耀眼,在地上投下了轮廓鲜明的影子。A项being thrown属于现在分词的被动形式,表示被动意义;B项throwing是现在分词,表示动作正在进行,常在句中作伴随状语;C项to throw 是动词不定式,表示将来的动作;D项to be thrown是不定式的被动形式。根据句意判断,此空格处应该填入一个能作伴随状语,且和句子的主语在逻辑上构成主谓关系的非谓语动词形式。首先排除A、D两个选项,因为这两个选项在逻辑上和句子的主语是动宾关系;C项虽然可以和句子的主语构成逻辑上的主谓关系,但是其常用作目的状语或结果状语等,不能用作伴随状语,所以也得排除。剩下的B项既符合语法规则,也符合语意逻辑关系。故答案选B项。
