A friend of mine met with an accident driving in darkness. His legs were so hurt that he couldn’t move. What was the 1 was that he found himself unable to ask for help — his mobile phone went out of 2 as a result of exhausted battery (耗尽电池) . Nothing could be done but 3 in cold wilderness. It was 8 hours later that day broke, and then the 4 of the rescue. It is almost 5 that he could stand the horror in the darkness for so long. Even more surprising was his 6: “First of all I checked up my 7 conditions and found myself not in fatal er. As there was no 8 to call for help, I leaned back in my seat trying my best to keep the wound from 9 . In this way I dozed off.” His story put an end to my regret for the 10 of an exploration adventure that happened last year. A group of young men 11 to explore a mountain cave (洞穴) and got lost. 12 to find a way out in the dark cave they were frightened and ran anxiously without a sense of 13 . Finally they fell dead in fear and exhaustion (筋疲力尽) . According to the 14 people that found them, the place where they got lost was only about 10 meters away from the 15 of the cave. If they stayed on the spot when they lost their way and tried to 16 themselves, they would probably sense a faint light shining not far away. Don’t you think that you can compare it with 17 itself? When you meet with obstacles ( 障碍 ) in life and work, you are lost in darkness. 18 you it’s unclear yet and you needn’t put up struggle 19 . It seems to be a negative attitude, 20 a person who can afford to do so must have foresight as well as a great courage in the first place.
