Suppose you were travelling to Southeast Asia on a cruise ship.You had saved up your allowance for more than a year for the trip.You were excited and had a fresh determination to see and learn a lot on the trip by yourself.One night on the ship, the deck suddenly became noisy.When you went to the deck, smoke started to come out of the engine room and a fire started spreading.The cruise ship was in serious danger.You hurriedly jumped off the deck and got in a lifeboat.Unfortunately, the lifeboat capsized and you strived not to drown, but eventually lost consciousness.When you slowly came to the next morning, you found yourself on a desert island.Could you survive on the desert island?
You felt so thirsty as soon as you woke up.Is it OK to drink sea water? Of course not.There is a difference between the thickness of sea water and that of human blood.Actually sea water is much thicker than human blood.If a man drinks sea water, the body requires even more fresh water than usual to return to its normal state.This is why you grow thirsty when drinking sea water.
There is usually water if you dig in a dry ravine(山沟).Sand and gavel are good at holding rainwater, so it is easier to find groundwater than it seems.Also, digging at places where there are random patches of grass also produces water.However, if it is dirty water that cannot be used for drinking, it must be filtered.You may filter the water by using pebbles and sand.Or you can distill fresh water from sea water.
After drinking water, you feel that you need a fire.How can you make a fire? A fire is very difficult to make in nature.It takes a lot of practice.You cannot expect to come across a spontaneous fire in nature.You can use either solar energy or friction.You must use a magnifying glass or a convex lens of binoculars to use solar energy.If you don’t have either, a plastic bag holding water or a clear glass container filled with water will work.Making a fire by friction in not easy.It takes a lot of patience.
To be rescued, you should write "SOS" in big letters with rocks on the beach and also light a fire.There is an international regulation for the rescue fire you light when shipwrecked.If you draw a large triangle on the ground, then light a fire at each point, it becomes the "3 point fire" that the International Civil Aviation Organization has chosen as the emergency rescue signal.During the day it is more effective to use smoke than fire.You can make thick smoke by burning fresh wood or green leaves.
