完形填空. A friend of mine met with an accident driving in darkness.His legs were so hurt that he couldn't move.What was the worst was he found himself unable to ask for help-his mobile phone went out of __ 1 __as a result of exhausted battery.Nothing could be done but to __ 2 __in cold wilderness.It was 8 hours later that day broke,and then the __ 3 __of the rescue. It was almost __ 4 __that he could stand the horror in the darkness for so long.Even more surprising was his __ 5 __:'First of all I checked up my physical conditions and found myself not in mortal (必死的) danger.As there was no __ 6 __ to call for help,I leaned back in my seat trying my best to keep the wound from bleeding.In this way I dozed (打盹) off.' His story put an end to my regret for the __ 7 __of an exploration adventure that happened last year.A group of young men tried to explore a mountain cave and got lost.__ 8 __ to find a way out in the dark cave.They were frightened and ran anxiously without a sense of __ 9 __. Finally they fell dead in fear and exhaustion (筋疲力尽)．According to the __ 10 __people that found them,the place where they got lost was only about 20 meters away from the __ 11 __ of the cave.If they stayed on the spot when they lost their way and tried to __ 12 __themselves, they would probably sense a faint light glimmering (闪烁) not far away. Don't you think that you can compare it with __ 13 __itself? When you meet with obstacles in life and work,you are lost in darkness.__ 14 __you it's unclear yet and you needn't put up struggle __ 15 __.It seems to be a negative attitude,but a person who can afford to do so must have foresight as well as a great courage in the first place.
