题目内容：

Our decision is that the school ______ closed.
A .remain B.remains C.remaining D.is remained

优质解答

Our decision is that the school should remain closed . 我们决定这个学校还是不开放.这是一个含有表语从句的复合句.主句是：our decision is , 表语从句是：that the school should remain closed.在这个从句中使用了虚拟语气,即：谓语结构为——should + remain (动词原形), 且谓语中的情态动词 should 是可以省略的.由此可见,含有表语从句的复合句中的主句中的主语含有“decision”这个表示“决定”的名词时,表语从句要用虚拟语气.
