the united states has many different kinds of climate . on the west coast the temperature changes very little between summer and winter. but the north central states have a very different kind of climate. in those states, people wear light clothing during the summer, and they need heavy wool or fur clothing in the winter.

　　in the southwest, the climate is pleasantly warm during the winter, but the summer is unpleasantly hot.

　　in the eastern part of the united states,summer temperatures are very different from winter temperatures.summers are usually hot,and winters are usually cold.spring temperatures are comfortably warm, and fall temperatures are pleasantly cool.

　　years ago, people in the cold parts of the united states didn't often get fresh vegetables and fresh fruits during the winter. today, however, trucks and trains carry fruits and vegetables very quickly to all parts of the united states. in this way, americans "send their climates" to people in other states.
