Our school library ___from 9:00 a.m to 4:00 p.m every day.
A. is opened B.is opening
C.is open D.opens
Our school library ___from 9:00 a.m to 4:00 p.m every day.A. is opened B.is opening C.is open D.opens
C is open
后面from 9:00 a.m to 4:00 p.m是一个长长的时间段,符合这个时间段的必须是个能够延续的动作,也就是必须是个延续性动词,而open作为动词本身只是一个打开的动作,打开的动作只有那一刹那,因此是非延续性动词.
A,B,D都是把open作为动词来用的,你看,A is opened是open作为动词的被动用法,B is opening是open作为动词的现在进行时,D opens是一般现在时,所以这三个选项都只能表现一刹那的动作.
而C is open中open是形容词了,开放着的,给school library定了性,是持续开放着的library,具体持续开放的时间是从上午9点到下午4点.
个人意见,希望有助于你理解这道题的用意,老题了,考来考去无新意.
D. opens
因为有every day,所以用一般现在时
D
C
opens
D
C
选择C open这里做形容词 因为open有形容词性 所以is openid 和 is opening 就多此一举了
from 9:00 a.m to 4:00 p.m every day. 是一个时间段，所以应该用延续性形式 而不能用一般现代时
支持C
