They sat there silently,With their eyes[]on the lake.该填fixed/fixing.为啥

问题描述:

They sat there silently,With their eyes[]on the lake.该填fixed/fixing.为啥
那为什么,they got a gift,with a note attaching on it.要用现在分词?

fixed,独立结构,表伴随状况
FIX这个动作并不是eye主动发出来的 而是they让eye发出来的
可理解成they fix their eyes on the lake
把eyes提前改成被动也就是their eyes are fixed on the lake所以用过去分词
