Nowadays, a lot of museums open to the public for free, and a lot of people are attracted to go there. However, it also brought some unexpected problems.
如今，很多博物馆都向公众免费开放，吸引了很多人前往参观。然而，这也带来了一些意想不到的问题。

At present, people can get knowledge from many ways like libraries, internet, and other sources. However, there is also much information that people cannot get from the above ways. Free admission museums supply more chances for the public to get knowledge that cannot be easily accessed. People can learn more things about history, art, science and so on. Although, this kind of policy brought much convenience to the public, it also caused some problems. For example, beggars and shabby-dressed people may enter the museums and cause bad reputation among the public; along with the increasing number of people getting into museums, there will be no enough service establishments to meet the requirements; besides, under the policy of free admission, the cultural relics displayed there may be inevitably broken or damaged by the crowds. Moreover, the crowds in the museums may also cause security problems.
目前，人们可以通过图书馆、互联网等多种途径获取知识。然而，也有很多信息是人们无法从上述途径获得的。免费开放的博物馆为公众提供了更多获取知识的机会。人们可以学到更多关于历史、艺术、科学等方面的知识。虽然这种政策给公众带来了很多便利，但也带来了一些问题。例如，乞丐和衣衫褴褛的人可能会进入博物馆，在公众中造成不好的口碑；随着进入博物馆的人越来越多，将没有足够的服务设施来满足要求；此外，在免费开放的政策下，博物馆展出的文物可能会不可避免地被人群打破或损坏。此外，博物馆内的人群也可能造成安全问题。

In my opinion, free admission is a good policy for the public, and it brings the public much convenience. But, we should also take possible measures to protect the cultural relics and maintain the order of spot. Besides, we can also take the policy of giving free admission first to children, then to the retired person, and last to the public. I think, this may help to solve the problems.　
在我看来，免费入场对公众来说是一项好政策，它给公众带来了很多便利。但是，我们也应该采取可能的措施来保护文物和维护现场秩序。此外，我们还可以采取先给儿童免费入场，然后给退休人员免费入场，最后给公众免费入场的政策。我认为，这可能有助于解决问题。
