Researchers comparing the immune systems of healthy, first-year law students under stress found that students who were optimistic maintained higher numbers of blood cells, compared with their more pessimistic classmates.
请问老师,第一个comparing是作定语修饰researchers还是时间状语,作状语也没逗号?第二个是时间状语吧?
Researchers comparing the immune systems of healthy, first-year law students under stress found that students who were optimistic maintained higher numbers of blood cells, compared with their more pessimistic classmates.
1. comparing...短语是用作定语修饰researchers,相当于简化的定语从句:
Researchers who had compared the immune systems of healthy, first-year law students under stress...
2. compared with their more pessimistic classmates 是时间状语,可视为前面省略了时间连词 when:
...when compared with their more pessimistic classmates.
Researchers【主语】// comparing the immune systems of healthy, first-year law students under stress【后置定语】// found 【谓语动词】// that students who were optimistic maintained higher numbers of blood cells, compared with their more pessimistic classmates【宾语从句】// .
参考译文:比较了法学院一年级且身体健康的学生在压力下的免疫系统的研究者们发现乐观的学生比悲观的同学拥有更多的血细胞。
备注(1):句子主干为: Researchers+ found +that宾语从句
备注(2):comparing the immune systems of healthy, first-year law students under stress为现在分词短语作后置定语。相当于who compared ...under stress
备注(3):found为主句谓语动词。
以下是宾语从句语法结构分析供网友参考
that【连词】// students 【主语】// who were optimistic 【定语从句】// maintained【谓语动词】// higher numbers of blood cells【宾语】// , compared with their more pessimistic classmates【时间状语】//
参考译文:乐观的学生比悲观的同学拥有更多的血细胞。
