For more than 200 years, the American flag has been the symbol of our nation's strength and unity。
It's been a source of pride and inspiration for millions of citizens. And the American Flag has been a prominent icon in our national history. Here are the highlights of its unique past。
美国国旗为长方形，长宽之比为19：10，为星条旗(the Star-Spangled Banner)，旗面左上角为蓝色星区，区内的星数于有关部门规定，美国的州数就是国旗上的星数。
星区以外是13道红白相间的条纹，13道条纹代表最初北美13块殖民地。据华盛顿说：红色条纹象征英国，白色条纹象征脱离它而获得自由。
