People would show different preferrence to indoor activities and outdoor activities. Some may be　interested in spending their leisure time indoors, while others may be fond of the latter. As far as I　am concerned, I would always prefer to be outside for my leisure activities.

　　In the first place, outdoor activities can privide me a pure natural enviroment in which I will feel　mure relaxed and refreshing. For example, I can always feel regenerated only after one-hour　jogging along a quiet street, with the fresh cool air and halmy wind around. Moreover, it is a real　fun to travel and enjoy so many wonderful sightseeings in different places. During their vacation,　most people would choose to travel to enjoy a period of leisure time so that they can refocuse on　their studies and businesses.

　　In the secong place, participating in varied outdoor activities can help us increase knowledge　through our own experience and widen our horizon. As a famouse Chinese saying goes: to become　wiser, you need to not only read 10 thousand books but also travel 10 thousand miles. It is true　when we go out we have the chance to meet different people and different things, which cannot　happen if you stay indoors. We chat with people and exchange ideas, we visit many places and　learn different cultures, all of which can let us know more about a true world.

　　In conclusion, I personally prefer ourdoor activities to indoor ones not only because I can enjoy　the relaxation and refreshment in the nature but also through participating in varied out activities,　I gain valuable opportunities to convert theoretical knowledge from books into a kind of real　experience.
