These are truths completely established with physiologists, and upon which it is undeniable that a great portion of human happiness depends.
这些真理完全是由生理学家确立的,是毋庸置疑的,人类的幸福在很大程度上依赖于这些真理。
请教曹老师,
1. Which指代什么?
2. and upon which …… 中的and 是否多余?主句和定语从句之间为何用and?
谢谢曹老师。
1 which指代truths。2 and并列truths的二个定语,只不过第一个定语是过去分词短语,第二个定语是定语从句。我们可以把过去分词短语视为定语从句的简略如下句,就可以理解and的使用了:
These are truths which are completely established with physiologists, and upon which it is undeniable that a great portion of human happiness depends.
