(英译汉)In addition to the need for food, man also has need for some kind of protection from heat and cold, and from wind and rain. The first homes of man were very simple. The size and kind of buildings which he built were limited by his technical knowledge and also by the kind of buildings materials(which were)available to him. Climate also had an important influence.
