看到书中有这样一句话:
Studies by Hargrave and Geen estimated natural community grazing rates by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers.
对于该句的分析为:先是主句,后面是两个由非谓语动词构成的方式状语,在最后一个状语中,又出现了一个现在分词作为定语来修饰前面的状语。
我没有读懂最后一句,为什么现在分词做定语修饰状语?有这种用法吗?还是我理解有误呢?
想麻烦曹老师帮忙解答一下。
Studies by Hargrave and Geen estimated natural community grazing rates这是主谓宾结构;by measuring feeding rates of individual zooplankton species in the laboratory and then computing community grazing rates for field conditions using the known population density of grazers 这部分整体是一个by介词短语作estimated的方式状语。其中介词by后接并列的动名词短语measuring...and then computing...作介词的宾语。using the known population density of grazers为现在分词短语作动名词computing的方式状语,是动名词短语的一部分,不单独分析。
