同学你好，该知识点来自沪江网校《2023年11月CATTI笔译二级【韩刚签约班】》的课程，想要更系统的学习，欢迎进入课程学习。不仅可以和更多的同学一起学习，而且还有老师、助教随时的学习指导和知识点解答哦。

同学好
1.an significant player 应为a significant player
2.clean只有形容词和动词词性，不能做名词，它的名词是cleanness。
clean of water 应为cleanness of water
3.with their immune systems are more accustomed,
with的复合结构由with+宾语+补足语构成，在句子中通常充当定语或状语，它不是动词或独立的句子，因此应该是with their immune systems more accustomed哦~
4.comparing their urban peers应为compared with their urban peers；
希望对同学有帮助~
