Chicago is known as the "Windy City". Some people think this is because of the breeze that blows almost constantly. The city is located in the state of Illinois on the shore of one of the Great Lakes, Lake Michigan, which is the fifth largest freshwater body in the world. Chicago may also be called the windy city because of the wind tunnel effect created in downtown by many tall buildings.
芝加哥被称为“风城”，有些人认为这是因为它不断有风吹来。这座城市位于伊利诺斯州的密歇根湖沿岸，密歇根湖是世界第五大淡水湖。芝加哥被称为风城，可能是因为许多高楼大厦在市中心产生的风洞效应。
Skyscrapers are an important part of Chicago's history. The first skyscraper in the U.S. was built in the city in 1884. At only 10 stories, it was impressive for its time. The skyscraper was eventually demolished. Chicago is the home of other famous firsts. It was the birthplace of the refrigerated rail car, mail-order catalogs, the car radio, the TV remote control, the first Ferris wheel, the first steel rail road, the first planetarium in the Western Hemisphere. Chicago is also the home to the first blood bank and the first drive-in bank. It is also the home to The Lincoln Park Zoo, the oldest public zoo in the U.S. Maybe the windy city should be called the city of firsts.
摩天大楼是芝加哥历史的重要组成部分。美国的第一座摩天大楼建于1884年。它只有10层，但是在当时已经很了不起了。这座摩天大楼最终被拆毁了。芝加哥是著名的创举之乡。它是冷藏火车车厢、邮购目录、汽车收音机、电视遥控器、第一个弗累斯大转轮、第一条钢道、西半球第一座天文馆的诞生地。芝加哥也是第一血库和第一家银行的所在地。它也是林肯动物园——美国最古老的公共动物园之家，也许风城应该被称为“第一城”。

From the Sky deck visitors can see four states: Indiana, Illinois, Michigan, and Wisconsin.
