It may be a cheetah, the fastest animal on land. It can run up to 70 miles an hour. It is faster than most cars moving on the highway! The cheetah is famous for its speed (速度) . It has long legs and a spring-like backbone. They can help it run fast. Although the cheetah can run fast, it can’t run for a long time. Cheetahs use their energy very quickly and become tired easily. If the cheetah can’t catch its food quickly, it will have to rest for a while before trying again. A cheetah is also a great hunter (狩猎者) . A cheetah’s coat is useful. It is light brown with black spots. It helps it to hide (隐藏) in the tall brown grass in Africa. Other animals do not see it hiding, so a cheetah can get close to rabbits, birds, and other animals quietly. Besides, it has excellent eyesight. A cheetah can see other animals far away. Good eyesight helps the cheetah find other animals easily. Today the cheetah is in danger. Many parts of Africa are being turned into farms. This change makes it necessary for the cheetah to find new places to live. Lions and hyenas are also hunting cheetahs. Luckily, zookeepers and wildlife experts (专家) are trying to protect the cheetah. 1. What’s the cheetah famous for? A. Its speed. B. Its coat. C. Its spots. D. Its eyesight. 2.
