18. Plants are more efficient at acquiring carbon than are fungi, in the form of carbon dioxide, and converting it to energy-rich sugars.这里in the form of carbon dioxide做同位语吗？同位语应该是名词修饰名词，可是这个是个介词短语作者: nokidding 时间: 2013-3-12 19:09
in the form of carbon dioxide不是同位语，是插入语修饰carbon，当做一个补充信息的不必要修饰。。。。。作者: zhanghaolin 时间: 2013-3-13 06:42
