同学好～

1. 同学是否想用dorm的复数形式变成 the dorms？
例如：
But you can't move out of the dorms until you're a junior.  
但是要到大三才可搬出宿舍。

2. 计划人数可参考表达：the number of diners
例如：
Consumers dial the telephone hotline of this website which starts with 400 and then this website notifies restaurants of reservation information. Fees are charged according to the number of diners.  
让消费者拨打本网站400热线电话，本网站再向餐厅告知订餐信息，按照用餐人数向餐厅收费。

祝同学学习愉快～
