China has many different kinds of climate (气候).In the southern part of China,the temperature changes very little between summer and winter.But the north central states have a very different kind of climate.In those countries ,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 smnmer is unpleasantly hot.
In the eastern part of China,summer temperatures are very different from winter temperatures.Smnmers 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 China 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 China.In this way,Chinese "send their chmates" to people in other states.生词：wool[羊毛]；trucks[卡车].
