1个简单英语单选题
The event included a number of lectures and workshops that were __ to the public.
A open
B opens
C opened
D opening
答案怎么选A.难道不是C?

答

C是过去式，Were也是过去式，所以不能悬C

答

be open to是固定搭配
对…开放；愿接受…的
eg：School playgrounds will be open to the public.
学校的游乐场也将对公众开放。
有不明白的地方再问哟，祝你学习进步，更上一层楼！ (*^__^*)

答

选A,因为这里的open是当形容词来用的,意思是“公开的,开放的”.不是做动词用,所以不选C.
请及时采纳,多谢!

答

that引导定语从句指代先行词workshops 在定语从句中做主语
be open to对....开放这里open作形容词对...开放的，开业的
open作为动词时打开的意思开门，开窗户，打开盒子等，所以不能选C
