题目：Some peoples say that public museums and art galleries will not be needed because people can see historical objects and works by using computers. To what extent do you agree or disagree?
范文：With more functions added to computers, whether museums and art galleries will be substituted by computers is earnestly concerned by the public. Some people believe that exhibitions will not be needed. However, I disagree with this argument. From my perspective, museums and art galleries will not be replaced.
On the one hand, going to museums and art galleries can deeply understand knowledge. This is because some studying puzzles can only be answered by visiting exhibitions. When facing some traditional tools, for example, students may understand what textbook said, such as how low the working efficiency was in the ancient time. However, if watching videos online, pupils may probably not make sense of these problems. Therefore, the educational means that museums and galleries contain may never demolish.
On the other hand, some details of historical objects and works can only be observed in the museums and art galleries. The reason of this is that people can closely observe these things in front of the display shelves. For instance, if painters want to know how painting materials influence the drawing pieces, they have to go to art galleries to watch them. Additionally, because some special painting perspective cannot illustrate on the digital screens, the public have to go to the exhibitions to enjoy the best appreciation. Thus, museums and art galleries are necessary.
To sum up, museums and galleries are useful for people to deeply understand the knowledge and see the details of the objects and master pieces. Only in this can the public know more about the culture.
