As humans，we are also considered as animals sometimes!But unlike other animals，we have not had to fit the environment in which we live．Instead，we have been the shaper （改造者） of our environment and explorer of nature．While other animals must find a home，we have created our home wherever we are living．We have fitted ourselves in a variety of environments．

Our skill at doing this has been due to our imagination，creativity and enthusiasm．If we chose to live in the desert，we learned how to save water，build a home among the rocks and mountains and depend on animals rather than vegetables for our food．Sometimes it was necessary for us to follow the animals as they moved，in order not to lose our source of food．

Living in a place where there was plenty of rain and mildtemperatures，we learned that we could plant a greater variety of crops，raise a few animals in a smaller，more contained area and not have to move our home．We have been able to live wherever we choose because we have not accepted the limitations of a particular environment，or rather，we have made the environment fit our needs．
