有一个例句是：
It is not proper that you (should) wear a cap while eating.
是不是这种It is proper that 句型接从句要用should加动词原形的虚拟语气．

在It is/was +形容词后的that 从句中用should的结构, should 可以省略. 这类形容词常见的有: advisable, anxious, compulsory, crucial, desirable, eager, essential, fitting, imperative,impossible, improper, important, natural, necessary, obligatory, possible, preferable, probable, recommended, urgent, vital etc
