It is important that foreign language classes be staffd with good teachers.

问题描述:

It is important that foreign language classes be staffd with good teachers.
classes 后面为啥用be呢?that 后面不是引导一个从句么,所以应该是一个独立的句子吧,所以我觉得应该用are啊= =求牛人们指点!

这是虚拟语气特殊形式之一:It is+good(应该的),wrong(不当的),important(重要的),necessary(必须的)+that+主语+should+原形动词,should可以省略.It is important that we (should) learn English well.学好英语...
