uncharted 考研GRE

The ship had drifted into uncharted waters.

船漂到了海未载明海域。

Far out in the uncharted backwaters of the unfashionable end of the western spiral arm of the Galaxy lies a small unregarded yellow sun.

在银河系西螺旋臂末端那片未曾标明寂静虚空中.悬挂着一颗不被人注意小小黄色太阳.

As I opened up the computer to try and fix the problem, I realized that I was getting into completely uncharted waters and considered whether to leave it to the experts.

当打开电脑打算修理，意识到这是一个自己一无所知领域，于是考虑要不要请专业人员帮解决。
