那在prep 33里面,D选项,最后一个分句: XXX Baikal holds 20 percent of the world's fresh water, which is more than all the North American Great Lakes combined. 笔记里面说,which的分句之修饰了fresh water而不是“20 percent of the world's fresh water”,这不是和你说的第三种which的用法矛盾了么?
which的三种用法:1.svo,which vo(which后接不完整句,which在从句中作名词性成分,指代前句宾语) 2.svo prep+which svo (介词+which后接完整句,prep+which作宾语补足语,which指代前句宾语) 3.svo, some/10%/5[百分比结构] of which v o(which后接不完整句,百分比结构+which作名性成分, which指代前句宾语)
