Obviously when classes aren't actually in session the dress code is considerably more relaxed and students can essentially wear what they want, but when they're on actual educational time they're required to suit up in their standard school uniforms. 很明显，在不上课的时候，学校的着装要求要宽松得多，学生基本上可以穿他们想穿的衣服，但在实际上课的时候，他们被要求穿标准校服。 Both in the Harry Potter books and films, it seems like the Hogwarts Great Hall is basically the heart of the entire school. Kids seem to spend a lot of their downtime there, and nearly every major school event takes place there, which is in addition to the hall serving as the school's cafeteria. 在《哈利·波特》系列丛书和电影中，霍格沃茨礼堂基本上是整个学校的“心脏地带”。孩子们似乎在那里度过了很多休息时间，大厅除了作为学校的自助餐厅，几乎所有学校的主要活动都在那里举行。 And surprisingly it would seem that this is very much the case for the average UK boarding school as well. The schools are massive and have all of the facilities required to offer children an education as well as a home, but the dining area is typically the place where everything significant happens. 令人惊讶的是，这似乎也适用于普通的英国寄宿学校。学校规模巨大，具备为孩子提供教育和家庭所需的所有设施，但用餐区通常是所有重大事件发生的地方。
