The hospital let me have a few days’ holiday, so I decided to go into the jungle and 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 big cats, especially tigers. We climbed onto the elephants’ backs to get better view, but it is unusual to find tigers in the afternoon because they sleep in the heat of the day. Then we saw a tiger a little far away from us. Kamal told me to be very quiet. We crept (爬行) nearer and found a dead deer (鹿), still bleeding (流血). This was the tiger’s lunch! Suddenly I started to feel very scared. We heard the tiger a second (秒) before we saw it again. It jumped out so quickly. I looked into its eyes and face, and saw right down the animal’s throat. It took hold of Kamal’s leg between its teeth, but I succeeded in pulling (拉) Kamal away. One of our elephants ran at the tiger and made it go back into the grass, so we quickly escaped to let the tiger eat its lunch. That night it was impossible to sleep! 根据短文内容,选择最佳选项。(10分) ( )36.
