Begin level

If this warming up took place, the ice caps in the poles would begin to melt, thus raising sea level several metres and severely flooding coastal cities.

如果这种变暖发生，两极的冰帽将开始融化，从而使海平面上升数米，并严重淹没沿海城市。

We start taking small risks at this level because we begin to share our own thoughts, opinions and beliefs.

在这一层次我们开始承担很小的风险，因为我们开始分享自己的想法，观点和信仰。

You begin to place situations in context to assess their danger level, and you begin to trust your own instincts.

你会开始根据实际情况来分析问题，判断危险的级别，并且开始相信自己的直觉。
