A man does not know the difficulty of anything_________ he does it personally.

A. although     B. if            C. because       D. unless

If you see someone drowning, speed is very important. Once you get him out of the water, if he isn't breathing, you have four minutes before his brain is completely destroyed. Support his neck, move his head back and press his chin upwards. This stops the tongue blocking the airway in the throat and is sometimes enough to get him breathing again. If that doesn't work, start mouth-to-mouth breathing. Press his nostrils (the two holes at the end of your nose, through which you breathe and smell things) together with your fingers. Open your mouth and take a deep breath. Blow into his lungs until his chest rises, then remove your mouth and watch his chest fall. Repeat twelve times a minute. Keep doing until professional help arrives.
To bring a child back to life, keep your lips around his mouth and gently blow into his mouth. Give the first four breaths as quickly as possible to fill the blood with oxygen. If, in spite of your efforts, he starts turning a blue-grey colour, and you can feel no pulse(脉搏), then pressing is the last chance of saving his life.
With arms straight, rock forwards, pressing down on the lower half of the breastbone. Don't be too hard or you may break a rib. Check how effective you are by seeing if his colour improves or his pulse becomes independent to your chest pressing. If this happens, stop the pressing. Otherwise continue until rescue arrives.

  The Pathfinder

    When we found him, he was a sorry sight. His clothes were torn, his hands bleeding. Before we reached him, we saw him fall. He lay a moment. Then he pulled himself to his feet, walked unsteadily a few yards through the woods and fell again.

         After we got him out, we went back to find the gun that he had thrown down. His tracks showed that for two days he had circled in the forest, within 200 yards of the road. His senses were so dulled by fear and tiredness that he did not hear the cars going by or see the lights at night.

         We found him just in time.

         This man, like others before him, had simply been frightened when he knew he was lost. What had been a near disaster might have turned out as only a pleasant walk, had he made a few preparations before he stepped from the highway or off a known path.

         Whatever sense of direction that a man may have, it’s still largely a question of observation. A skilled woodsman always keeps an eye on his surroundings. He notes that the shape of a mountain, the direction water flows through a swamp, and the way a tree leans across a path. With these in mind, he may be turned around many times, but he is seldom lost.

         There are exceptions, of course, and once in a while a man does come across some strange problem that puts him into the “lost” situation. A rainstorm or sudden blizzard may catch him without a compass（指南针）in his pocket. Darkness may find him in a rough area, where travel is dangerous without a light.

         When this happens, the normal first reaction（反应）is the fear of being laughed at as a result of his poor knowledge in the woods. He may also be concerned about the inconvenience that he will cause his friends when he doesn’t show up. This false pride may lead him to keep on the move in a false effort to find his way against all difficulties.

         The person who thinks ahead is seldom in great danger. He’ll be safe if he observes carefully, thinks ahead, and remains calm.
