You see, my boat is sinking! There is a desert island nearby. I can swim there, but I can only take one bag with me.

May be I will take 4 things along.

The first one is the compass. A compass is a navigational instrument for determining direction. This will be helpful, which helps me not to get lost wherever I am. And of course I can use it rather well.

The second thing will be the tent. The reason why I choose the the tent is that I can stay in, can sleep, can take rest in there. We all can skip eating for 2 to 3 days but you must sleep to keep you awake.

The next will be the lighter.Why is there a need for fire? With fire, you can cook food, boil some water, warm your body and especially scare away wild animals. Warm weather? What would happen if weather becomes cold at night? Of course It is advisable to burn a little bit of wood to keep you warm. If the fire is strong enough, you can burn some fresh twigs to create smoke, calling the attention of rescuers.

And you remember the movie King Kong? Well, you are on that island. Not only do you have to survive, but you have to avoid King Kong, dinosaurs and very large flying insects. That fire can keep you safe well too.

And the last, hmm may be the knife. I think I will be hungry without food. I can catch fishes for example, then use the knife to dissect them, at last use the lighter to cook it.

So, to conclude, I need four things to bring along: compass, tent, lighter àn knife to keep me full, strong and healthy enough to get home.
