英语语法We must have our classroom______(显得干净和明亮)是looked clean a

英语语法
We must have our classroom______
(显得干净和明亮)
是looked clean and bright 还是 look clean and bright?

楼上说的have...done确实是存在的,但是不是此句话要表述的东西.
下面给出牛津高阶词典中的词条原文
【have】* CAUSING OR ALLOWING SOMETHING TO HAPPEN 使或让某事发生
用法【1】
[Cn.i no passive 不用於被动语态] order or arrange (that sb does sth) 命令或安排（某人做某事）:
I`ll have the gardener plant some trees.我要让园丁种些树.
Have the driver bring the car round at 4.让司机4点钟把汽车开来.
用法【2】
(used with a n + past participle 与名词+过去分词连用)
[cause sth to be done]使某事物予以处理 or [suffer the consequences of another person's action] 承受、 蒙受他人行为之后果
We're having our car repaired.我们的汽车正在修理.
They have had their request refused.他们的请求遭到拒绝.
用法【3】
[Cn.g no passive 不用於被动语态] cause sb to do sth 使某人做某事:
She had her audience listening attentively.她使听众听得入神.
The film had us all sitting on the edges of our seats with excitement.这部影片让我们大家激动不已.
考察动词look,look本来自己就有这样的意思：
To seem or appear to be:似乎,显得：看似或看起来：
所以教室看起来怎样本来就是主动动作,没有理由用被动.事实上说classroom is looked 这样说是大错特错的.
因为look不及物,怎能让classroom做look的宾语呢?
这道题考察的是上面的用法【1】
have sth.do=make sth.do
事实上还有：
have sth.adj.= make sth.adj.
have sth.done = make sth.done
have sth.doing = make sth.doing
再进一步我认为
说【We must have our classroom look/appear clean and bright.】
与【We must have our classroom looking clean and bright.】
与【We must have our classroom clean and bright.】
是一样的.
