英语翻译
it is difficult to really experience or "feel" the size df the united states.to get the full impact you should realize,for example,that it takes 48 hours(two entire dayd and two long nights) to travel by train from Chicago to Los Angeles,rolling along hour after hour across wheat fields,mountains,and deserts.
Another way to think about it is to compare distances in the United States whit others more familiar to you.For example,New York to Wasdhington,DC.is about the same as London to Paris or Nairobi to Mombasa or Tokyo to kyoto;New York to Los Angeles is farther than Lisbon to Cairo or Moscow to Montreal or New Delhi to Rome.
Naturally,with such distances,the climate in the continental United States is also one of great extremes.From NEW England and New York through Chicago and much of the Midwest and Northwest,temperatures vary from subzero in winter to the high 90s(Fahrenheit) or over in summer.
The South and Southwest have warmer weather,though even these sections have occasional frosts and periods of moderate cold.Generally,summers are likely to range from 70F to 100F(21C to 38C),and many areas can be quite humid.However,air conditioning is so widespread that you can expect most office buildings and homes to be kept at relatively comfortable temperatures.

要真正体会或“感觉”美国的大小是很困难的.比如,为了获得完整的印象,你需要认识到,坐火车从芝加哥到洛杉矶要花费48个小时（两个整天和两个长夜）,一小时又一小时地从麦田、山岭和沙漠间颠簸而过.
另一种考虑这个问题的方法是将美国的各种距离与另一些你更熟悉的距离比较.例如,纽约与华盛顿的距离,大概与伦敦和巴黎,奈洛比与蒙巴萨岛,或是东京与京都的距离相同；纽约到洛杉矶的距离,比里斯本到开罗,莫斯科到蒙特利尔,或新德里到罗马的距离更远.
自然地,相差这样远的距离,大陆上的美国各地的气候也有着极大的差异.从新英格兰、纽约直到芝加哥以及中西部和西北部的很多地区,温度差异巨大,从冬天的零度以下,直到夏天的华氏九十度甚至更高的高温.
南部和西南部具有更温暖的天气,尽管即使是这些地区,偶尔也会有霜降以及适度寒冷的时期.一般地,夏天的气温通常在华氏70度至100度（摄氏21度至38度）之间,许多地区可能非常湿润.然而,空调的应用十分普遍,以致于你可以想见,大多数写字楼和家庭都保持在相对舒适的温度.
