The supermarket is open 24 hours every day求救!

问题描述:

The supermarket is open 24 hours every day求救!
The supermarket is "open "24 hours every day.还是The supermarket is "opens "24 hours every day.(说前者还是后者,或是open还是opens)
open在这里是形容词还是动词?(注意两个问哦)
回答问题是有福报地!

应该是前者,后者语法讲不通.形容词那这道题呢?I‘m too sleepy(困倦的),I want to s____ now.你好!这个用sleep,原因这是动词不定式结构,to加动词原形,sleep是动词。上题是主系表句型,open充当表语。
