问题描述：

A.measured\x05\x05\x05B.measuring
C.to be measured\x05\x05D.measures
我知道这题A和C选项是要去掉的,因为在这里measure做不及物动词没有被动语态,但是这题为什么不选D?答案是B（我想把每个选项都弄懂）
答
measuring 7.1 on the Richter scale是现在分词短语做后置定语,等于which measured.因为谓语是struck,所以此空只有选能做定语的非谓语动词which measured.=measuring 是这个意思吗?measure加了ing就是非谓语动词了吗？是的。 这是分词作定语， 现在分词表主动谢谢。记得【采纳】
