Free Admission to Museums
Nowadays,the pulic are given access to more and more museums without entrance tickets.
Some people hold the view that it will bring some problems.First of all,museums need money to support themselves .Since many admission tickets have been cancelled,most museums may get into trouble,lacking of fund.Then it will results in a more serious consequence that the museum feel weak in many activities and exhibition which are open to the public without restriction.So the damage is done to the public themselves in turn.
In my eyes ,free admission to museums benefits the public.In that way,everyone has a chance to enter the museums to add their knowledge and open their eyes.Everyone,poor or rich,has a equal right to involve in cultural exchange which can erich man’s inner life .In a large sense ,it contributes to the spiritual civilization construction.Although the trend may lead to heavy cost of museums ,the government should give them powerful support not only in finance but also in policy ,for museums can’t develop well on their own strengths.
In summary ,I suppose free admisson to museums is very necessary
and important.
