some day the eople who are bound to be faced with the same problem we had——getting rid of thisstuff.同位语get为什么加ing

非谓语

这好像不是一个完整的句子.因为the people是主语,而who are bound to be faced with the same problem we had是定语从句,修饰the people,那么谓语就是get,而getting不能做谓语.
难道had后面一杠横线还要填词?如果能填的话,就变成some day the people who are bound to be faced with the same problem we had（will be）getting rid of this.
