标题: 请教一道OG中SC的语法题 [打印本页] 作者: Z先生的MBA 时间: 2017-11-27 15:59 标题: 请教一道OG中SC的语法题 About 5 million acres in the United States have been invaded by leafy spurge, a herbaceous plant from Eurasia,with milky sap, that gives mouth sores to cattle and displaces grasses and other cattle food, rendering rangeland worthless.
上面这句话是OG中的一道SC题的正确答案,想请教一下that修饰的先行词是milky sap 吗?
“with milky sap”应该是插入语吧,那么如果去掉插入语不看,that的先行词是Eurasia吗?
那我的理解是:
a herbaceous plant from Eurasia,with milky sap, that gives mouth sores to cattle and displaces grasses and other cattle food, rendering rangeland worthless 是 leafy spurge的同位语从句,that 后面是修饰 a herbaceous plant
