这是什么从句求解答

Any proposals____the computer room___closed must be resisted.A.which;be B.that;must be C.that;be这是什么从句求解答
选C,是同位语从句,thatc 从句,从句的内容就介绍了proposals(提议)的内容,是对proposal的解释,所以是同位语从句.
从句中be其实是should be把should省去了,should在从句中被省的情况很常见,其他情态动词却没有它这么特殊可以省去.之所以不用must be是因为must be是对事实的强烈而肯定的猜测,表示“一定是”,并不是must 一般动词原型时可表示的“必须”的意思.

C
proposal是建议，后面的同位语从句用虚拟语气，即should加动词原形，美国英语里面这个should常常省略，这里用的是虚拟语气的被动语态，也就是should be closed，由于这里是同位语从句，而不是定语从句，所以用从属连接词that引导，这个that只起连接作用，在从句中不充当任何成分，是个“无名英雄”。希望我能帮助你解疑释惑。...

因为proposal是提建议的意思，用法跟suggest一样，后面的建议内容即名词从句要用should do sth，其中should可以省略，所以后面本来是should be closed省略了should就只剩下be closed，前面指代这个建议内容的不能用which，只能用that，所以选C
同位语从句吧。。
