during a long vacation, i usually like to go to see the exhibits in one of a great many museums. such as the art museum, the history museum, the museum of natural history, and the museum of science and technology. many wonderful things are cared for in museums.

　　there are paintings, potteries, sculptures, costumes, swords, ancient animal bones and plants, stuffed animals, antique steam locomotives, and many others. it is always a good review of history to visit those museums.
