    Recently, our class have had a heated discussion concerning that whether the Beijing Zoo should be moved out of the city. Some of my classmates approved of the moving .They say large crowds of tourist to the zoo will result in traffic jams .They also say that once moving, animals will have more space and good living conditions in the suburbs. Therefore, other students against the idea. They say that the zoo has the history of 100 years, and is famous at home or abroad. Moreover, moving may cause the dead of some animals. So, it's a better choice to remain where it is.
