　　Museums have changed. They are no   1    places where one “should” go but now they are places  2    .

        The purpose is    7    to provide fun, but also to help people feel at home in the world of science. If people don’t understand science, they   8   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.     9  cause is the growing number of young people in the population. Many of them are college students or college graduates. They see things in a new and different way. They want art that they can take part in. The same is 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 6, 000 museums, almost twice as    10   as there were 25 years ago.
