that will make perfect sense.

至少是趋向于来到美国
So for one thing--and in a way this sounds obvious

所以一方面你仔细想就会恍然大悟
once you think about it--people who migrated to the colonies

那些来到殖民地发展的人
tended to be risk-takers.

都是冒险家
These were people who were willing to take a risk.

他们都是愿意承担风险的人
They were willing to make the hazardous passage

他们愿意漂洋过海
across the sea, put themselves at a distance of several months' travel

经历几个月危险的旅程
from everything that they knew,

来到一个完全陌生的地方
and start life anew in what they assumed to be some kind of a wilderness.

在原始荒芜的土地上开始全新的生活
They were people who wanted something, maybe to better their condition,

他们有梦想想拥有更好的生活
and they weren't afraid to act on that desire, to reach for it.

而且一点也不惧怕追寻梦想打拼天下
Obviously, these are people who are going to be pretty independent

很明显这些人的独立性都很强
