Question

一道英语.
Recently,however,scientists have been finding that long-term use of these fertilizers can cause damage to the land and,even more dangerous,to people's health.
这个句子的结构,成分.
尤其是逗号后面的,好奇怪

Answer 1

句子是现在完成进行时态
scientists是主语,that引导宾语从句.
在宾语从句中,也就是that后面的句子中,long term use of these fertilizers是主语,and 前面的to the land 和to people's health 是并列结构.
