美國的空氣(The Climates of the United States)

fortably 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 (新鮮水果) 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.
