day5

The plane goes into the snow and stops.飞机落入雪中，停了下来。

It is very difficult to go past the rocks in the valley.山谷中的岩石很难攀爬。

You go on down the valley.你继续沿着山谷走。

You go back up the valley and into the tunnel.你往回走上了山谷，进了隧道。

You walk through the trees down the mountain你穿过树林向山下走。

the ice begins to move under your feet. You go on across the lake. 脚下的冰开始晃动。你继续在湖面上穿行。
