为什么这里要用must be 'Your sister will be here in less than an hour and we must be at the station to meet her.We are late already.' 这里单单用must不行么

解答
不可以去掉be动词.must是情态动词,后面要加动词原型的.所以必须加上动词. 举例: I must 【go 】home.正确 I must home.错误. 动词不能省略的!那you must becomeback home 呢 能不能用be,如果不能用那又是为什么呢不能用be,因为be和come都是动词,你只能选一个。要么说?:You must come back home要么说:You must be back home
