听力原文： Lions prefer to eat without having to do much work. When resting in the shade, they are also watching the sky. And if they see birds fly down, they immediately sense that something must be happening. Even in the heat of the day, they will certainly arise and run a mile across the plains to find out what is going on. If another animal has made a kill, they will drive it off and take the dead animal for themselves. A grown lion can easily consume 60 pounds of meat at a single feeding. Often, they eat until it seems painful for them to lie down. The female lions are leaner and swifter, and as a result, are better hunters than the males. Most kills are made at night or just before dawn. The kill is the most exciting moment in the day-to-day existence of the lions, since these great beasts spend most of their time—bout 20 hours a day—sleeping and resting. Lions are also social cats. And during these times of leisure, they love to tease against each other, and the young lions are always playing among themselves and with their parents.
