No, I don't think they should always be free. Museums need money to pay for things like staff, cleaning, and new exhibitions. If everyone could go for free, it might get too crowded and not be enjoyable. Also, when people pay for something, they might appreciate it more. Maybe some special events could be free, but not everything.
不,我认为博物馆不应该总是免费。博物馆需要资金来支付员工工资、清洁和新展览等费用。如果每个人都能免费参观,可能会变得过于拥挤,体验也会不好。此外,当人们为某样东西付费时,他们可能会更加珍惜它。也许一些特殊活动可以免费,但不是所有的都免费。
