Last year I worked in Nepalfor three months. When I had a few days off, I decided to go into the jungle(丛林). I asked a Nepalese guide, Kamal Rai, to go with me.

We started our trip at six in the morning with two elephants carrying our things. It was hot, but Kamal made me wear shoes and trousers to protect me from snakes. In the jungle there was a lot of wildlife, but we were trying to find tigers. We climbed onto the elephants’ backs to see better. However, it is unusual to find tigers in the afternoon because they sleep in the daytime.

Then, in the distance, we saw a tiger, and Kamal told me to be very quiet. We moved nearer and found a dead deer. This was the tiger’s lunch! Suddenly, I started to feel very frightened.

Then the tiger jumped out suddenly, about five hundred kilos and four meters long. It caught Kamal’s leg between its teeth, but I managed to pull Kamal away. One of our elephants ran at the tiger and made it go back into the grass, so we quickly ran away to let the tiger eat its lunch. That night it was impossible to sleep!
