(2015·郑州质量检测三)You may have heard of the American Dream，an ideal that has powered the hopes of Americans for generations.
It began as a belief that the US was a land of opportunity，and that anyone could achieve success through hard work.At times，the dream has referred to home ownership，a good job，retirement security or each generation doing better than the last.
Yet today，this concept seems to have greatly changed.As Time magazine pointed out，quite different from the older generation，many Millennials (the generation born after 1980) redefine (重新定义) the American Dream as “daytoday control of your life”．They “prize job mobility，flexible schedules，any work that is more interesting than typing，and the ability to travel”，said the magazine.
Home ownership，once the cornerstone of the American Dream，is becoming a smaller priority for this generation.Meanwhile，nearly 40% of them choose travel as part of their dream.And entrepreneurship (创业) is a rising favorite，as nearly 26% of Millennials consider selfemployment as part of their dream.
So what has led to this huge change?
