Song of the State州歌
Illinois
By thy rivers gently flowing，Illinois，Illinois，
O’er thy prairies verdant growing，Illinois，Illinois，
Comes an echo on the breeze．
Rustling（瑟瑟声，沙沙声）through the leafy trees，and its mellow
（（声音）圆润的）tones are these，Illinois，Illinois，
And its mellow tones are these，Illinois．
From a wilderness of prairies，Illinois，Illinois，
Straight thy way and never varies，Illinois，Illinois，
Till upon the inland sea，
Stands thy great commerical tree，
turning all the world to thee，Illinois，Illinois，
Turning all the world to thee，Illinois．
When you heard your country calling，Illinois，Illinois，
Where the shot and shell were falling，Illinois，Illinois，
When the Southern host withdrew，
Pitting Gray against the Blue，
There were none more brave than you，Illinois，Illinois，
There were none more brave than you，Illinois．
Not without thy wondrous（令人惊奇的，非常的）
story，Illinois，Illinois，
Can be writ the nation’s glory，Illinois，Illinois，
On the record of thy years，
Abraham Lincoln’s name appears，
Grant and Logan，and our tears，Illinois，Illinois，
Grant and Logan，and our tears，Illinois．
