请大家帮我解答一下这道英语单选题,并帮我讲解一下有关知识点,具体问题如下
The headmaster received a suggestion that the school——more optional courses.
A.open B.to open C.opened D.opening

选A,完整的是should be open,把should be省略了。表示建议的词后有这种用法

suggest后面用虚拟语气 从句为should+动词原型
在美式英语中should可以省略

A
suggestion后面加that引起的同位语从句或表语从句时,从句谓语用should + 动词原形,should可省略.

A
因为有一个suggestion,所以后面的定语从句或者同位语从句用虚拟语气,即should do sth.,should 可省略,所以选A
