拉斯维加斯气候
拉斯维加斯地处美国内华达沙漠边陲，周围环绕著1000米至3000米的高山。拉斯维加斯的气候四季分明。夏季是典型的沙漠性气候，正午的温度常常高达38゜左右，而晚间的温度相对凉爽。常常会有雷阵雨天气，温度要超出平均水准。冬季整体上是气候温和适宜，白天的平均温度在15゜左右。尽管偶尔会出现非常高温天气，但是春季和夏季仍然是最宜人的季节。拉斯维加斯很少受到恶劣气候的袭击，并且是全国所有的大城市中相对湿度最低的区域之一。 周围都是沙漠，和死亡谷一样干燥。因为少雨的缘故，空气会较为干燥，最好准备一点保湿用品。

美国首都华盛顿，全称“华盛顿哥伦比亚特区” (Washington D.C.) ，是为纪念美国开国元勋乔治•华盛顿和发现美洲新大陆的哥伦布而命名的。华盛顿在行政上由联邦政府直辖，不属于任何一个州。是美国文化、教育中心之一。位于马里兰州与弗吉尼亚州之间。

华盛顿原是一片灌木丛生之地，只有一些村舍散落其间。1789年，美国联邦政府正式成立，乔治•华盛顿当选为首任总统。当国会在纽约召开第一次会议时，建都选址问题引起激烈争吵，南北两方的议员都想把首都设在本方境内。国会最后达成妥协，由总统华盛顿选定南北方的天然分界线——波托马克河畔长宽各为16公里的地区作为首都地址（1790年）。城市规划为巴罗克建筑与凡尔赛、巴黎的建筑形式相结合，以国会大厦、白宫等建筑物为中心修建林荫大道向四方辐射，再于其间增筑格状街道，是由法国工程师皮埃尔•夏尔•朗方总体规划和设计。新都尚未建成，华盛顿便于1799年去世。为了纪念他，这座新都在翌年建成时被命名为华盛顿。
