When my family went on summer vacation, we usually made it a road trip,(23)which gave us the opportunity to play license-plate bingo and other fun car games that my brother and I loved. My parents hated them, but at least they kept us from killing each other in the backseat. We were constantly on the lookout for plates from faraway places, which led to our guessing where certain states’ nicknames came from. Some were obvious: Florida as "The Sunshine State" made sense, just like Delaware’s nickname, "The First State" was pretty self-explanatory. But we were always a little stumped(为难)by nicknames like "The Show-Me State. "(24)But when I think about the nickname of our own home state of Ohio, it turns out that some state nicknames and slogans have surprising origins. Most sources credit George Washington for coining this nickname. In 1784, he gave a speech in which he described New York as "at present the seat of the Empire," since at the time, the nation’s capital was New York City. By 1820, the nickname of "Empire State" had stuck.(25)Minnesota is called "Land of 10 000 Lakes." It may seem that this state owes its nickname to its plentiful supply of lakes, but it’s not really true that the state of Minnesota has 10 000 lakes. The actual number is more like 12 000. The history behind these nicknames is good knowledge to have handy, in order to break up backseat brawls while you’re on the road this summer. As usual, the truth is more interesting than fiction could ever be.
