We went hiking together on Monday, but became separated due to a heavy rainstorm. Without a compass, I lost direction, and now I am lost in dense jungle.There are no roads at all, so I have to make my own way step by step. I have hurt both my hands quite badly from all the thorns – they are everywhere. To make things worse, I stumbled and sprained my ankle. The pain is killing me! Snakes, monkeys, insects and other animals appear from time to time. Yesterday, I heard the roar of a tiger from far away. I was terrified! I rub sticks together to make a fire every night to keep myself warm and safe. It’s really a difficult technique to master, and it takes me several frustrating and worrying attempts every evening. I have to remind myself to be calm and optimistic at every moment.Food also worries me a lot. I’ve been eating berries to appease my hunger, but I have to be very careful to avoid anything poisonous.Today I have some luck when I find a stream which I can follow. It gives me great hope. I’m confident that I can find my way out! This will have been the most memorable adventure of my life! 展开更多...... 收起↑ 资源预览
