求翻译一篇英语短文
Museum have changed .They are no longer places that one “should “ go but now they are places to enjoy .
At a science museum in Canada ,you can feel your hair stand on end as harmless electricity passes through your body .at the children's museum in new York ,you can play an African drum .there are no 'do not touch 'signs in some other museum in the USA.
More and more museum directors have realized that people learn best when they can become part of what they are seeing .in many science museums,the visitors are encouraged to touch ,listen ,ooperate and experiment so as to discover scientific rules for themselves .
The purpose is not only to provide fun ,but also help people feel at home in the work of science .if people don't understand science ,they will be afraid of it ; and if they are afraid of science ,they will not make the best use of it .
One cause of all these changes is the increase in wealth and spare time .another cause is the growing number of young people in the population .many of them are college students or college graduates.they see things in anew and different way .they want art that they can take part in .the same iis true of science and history .
The old museums have been changing and the government is encouraging the building of new ,modern museums .in the United States and Canada ,there are more than 6000museums ,almost twice as many as there were 25 years ago .

博物馆已经改变了.他们不再是一个“应该”的地方,但现在他们欣赏的地方.
在加拿大的一个科学博物馆,你能感到你的头发竖立当无害的电流通过你的身体.在儿童博物馆在纽约,你可以玩非洲鼓.那里没有“不接触”的迹象在一些其他的博物馆在美国.
越来越多的博物馆已经意识到人学得最好的时候,他们可以成为他们所看到的东西.在许多科学博物馆,参观者鼓励接触,倾听,ooperate和实验等科学规则发现自己.
其目的不仅是为了好玩,但也让人觉得在家里的科学工作.如果人们不懂科学,他们会害怕它；如果他们害怕,他们将无法充分利用它.
一个原因是所有这些变化是增加财富和闲暇时间.另一个原因是越来越多的年轻人在人口中.他们中的许多人是大学生或大学graduates.they看事物在新和不同的方式.他们希望他们能参与.同样是真正的科学和历史.
旧博物馆已变,政府鼓励建立新的,现代的博物馆.在美国和加拿大,几乎两倍多有25年前.
给个最佳吧. 谢谢.
