Much attention should be paid_______the wild animals as many of them are dying out.

问题描述:

Much attention should be paid_______the wild animals as many of them are dying out.
为什么不是to protect表目的而是to protecting

pay attention to doing sth 是固定词组为什么不是“多加注意,目的是为了保护更多的野生动物”为什么to protect....不能来表目的,而只能用be protecting来表示be paid 的剩下部分呢后面还有一个as表示原因,如果两个表示原因的话句子逻辑似乎不通~
