Having passed what I considered the worst obstacle, our spirit【C1】______. We made towards

the left of the cliff, where the going was better, though【C2】______steeper. Here we found【C3】______snow, as most of it seemed【C4】______blown off the mountain. There was no【C5】______of the mountains in the distance because clouds were forming all around us.

About one o'clock a storm【C6】______suddenly. We ought to have noticed its approach but we were concentrating【C7】______outting steps, and before we had time to do anything, we were【C8】______by snow. We could not move up or down and had to wait motionless, getting colder and colder.【C9】______my hood(兜帽), my nose and cheeks were frost bitter and I dared not【C10】______a hand out of my glove to warm them.

After two hours of this, I realized we would have to do something to avoid being frozen【C11】______death. We stood from time to time through the mist, and I had【C12】______the outline of a dark buttress(扶垛)just above us; to descend in this wind was out of the【C13】______;our only hope was to【C14】______up to this buttress and dig out a platform. at the foot of it【C15】______we could put up our tent.

We climbed to this place and started to out away the ice. At first my companion seemed to regard the situation【C16】______hopeless but gradually the wind【C17】______and he cheered up. At last we had made a platform. big enough to【C18】______the tent and we did this as best as we could. We【C19】______into our sleeping bags and【C20】______sleep, feeling that we were lucking to be still alive.
