HSK Standard Course 6上, chapter 19 (original).
This is the first paragraph from a chapter in the HSK Standard Course 6上 textbook, which discusses deep sea life and how it survives without sunlight. The last sentence above seems very weird to me.
To begin with, the choice of the word
CC-CEDICT: 准则 (zhǔnzé) norm / standard / criterion
The second problem I see is the use of
CC-CEDICT: 定义 (dìngyì) definition / to define
It's not clear (to me, at least) what definition(s) the passage is referring to. I feel like it's referring to the prior-mentioned 真理, i.e. 没有阳光，就没有万物, but this is not a 定义. Moreover, the use of the word
CC-CEDICT: 质疑 (zhìyí) to call into question / to question (truth or validity)
seems inappropriate (to me) for describing 定义. Furthermore, the text makes it sound like scientists are making an important discovery, and not merely that some 定义 is inappropriate and needs modification.
I might be completely wrong about all this. However, in a previous chapter from this textbook, I compared the textbook's text with the original (unmodified) text, and the textbook "forces in" certain vocabulary items, and the result is unnatural.
Question: Is it just me or is 却向人类早已认定为准则的定义提出了质疑 terribly unnatural?
