【简答题】
Jungle country is not friendly to man, but it is possible to survive there. You must have the right equipment and you must know a few important things about woodcraft. Then your chances of staying alive are very good. No one should go into the jungle without the right equipment. You need light weight clothing, a good knife, and a compass. Fishhooks and a line, a rifle, matches in a waterproof container and a poncho are necessary too. So is a mosquito net to protect the head. In the jungle you can get hopeless lost within five minutes after leaving a known landmark. That is why you should always carry a compass. In open country, during the day, you can tell which way o go by studying the sun. At night the stars are sure guides o direction. But in most places the jungle rooftop is so thick that it is impossible to see the sun or the stars. Again and again you must check your position by the compass. Keep alert. Watch the ground in front of you carefully. Stop and listen now and again. Avoid haste, and rest often. In a place that is hot and humid, the person who sets a fast pace will soon become tired. A steady, even pace is wisest in the long run. If you lose your way, don’t panic. Try to desire how long it has been since you were sure of your position. Mark the spot where you are with blazes on a tree. Put them on four sides of the tree, so that you will be able to see them from any direction. Then you can begin retracing your steps, knowing that you can always find the spot from which you started. Except in an emergency, never try to travel through the jungle at night. Whenever possible, it is wise to follow streams and rivers that are going in your general direction. This may cause you many extra miles of travel. But in the end it will save time and energy. Nothing is more exhausting than hacking a trail cross-through umbrella jungle. If a river is broad and deep and has no rapids, rafting is the best means of travel. Bamboo grows along the banks of many jungle streams. Since it is hollow and extremely strong, it makes a perfect raft. Surviving in the jungle is a science. The jungle people have become perfect in this science, and you can too. Learn as much as you can about what to expect in the jungle. Make sure you have the right equipment. Then no part of the jungle will be able to “live off” it for a long time. 小题1: The author probably advises against traveling at night because ________. one tends to move too slowly at night some animals will attack you emergencies occur most frequently at night it is more difficult to check your position 小题2:Following streams and rivers will help you to ________. avoid animal’s attacks save many extra miles of travel avoid crossing unbroken stretches of jungle have a constant source of drinking water 小题3:The word “blazes” in Paragraph 5 means _________.
