A friend of mine met with an accident driving in darkness. His legs were so hurt that he couldn’t move. What was the       was he found himself unable to ask for help — his mobile phone went out of        as a result of exhausted battery. Nothing could be done but to       in cold wilderness. It was 8 hours later that day broke, and then the        of the rescue.
It is almost       that he could stand the horror in the darkness for so long. Even more surprising was his       : "First of all I checked up my        conditions and found myself not in mortal （致命的）danger. As there was no way to call for help, I leaned back in my seat trying my best to keep the wound from      . In this way I dozed （打盹）off ."
His story put an end to my regret for the       of an exploration adventure that happened last year. A group of young men       to explore a mountain cave and got lost.        to find a way out in the dark cave they were frightened and ran anxiously without a sense of        .Finally they fell dead in fear and exhaustion. According to the       people that found them, the place where they got lost was only about 10 meters away from the        of the cave. If they stayed on the spot when they lost their way and tried to        themselves, they would probably sense a faint light glimmering （闪烁）not far away .
Don’t you think that you can compare it with        itself? When you meet with obstacles （障碍）in life and work, you are lost in darkness.     you it’s unclear yet and you needn’t put up struggle        . It seems to be a negative attitude,        a person who can afford to do so must have foresight as well as a great       in the first place.

B．unimaginable
