     Lions are opportunists. They prefer to eat without having to do too much work. When resting in the

shade, they are also watching the sky to see what is flying by, and even in the heat of the day they will

suddenly start up 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 dill for themselves. A grown lion can easily eat 60 pounds of meat

at a single feeding. Often they eat until it seems painful for them to lie down.

     The lioneases (母狮), being thinner and faster, are better hunters (猎手) than the males (雄狮). But the

males don't mind. After the kill they move in and take the test share.

     Most kills are made at night or just before daybreak. We have seen many, many daylight attempts but

only ten kills. Roughly, It's about twenty daytime attempts for one kill.

     When lions are hiding for an attack by a water hole, they wait patiently and can charge at any second.

The kill is the exciting moment in the day-to-day life of the lion, since these great animals spend most of

their time, about 20 hours a day, sleeping and resting.

     Lions are social cats, and when they are having a rest, they love to touch each other. After drinking at

a water hole, a lioness rests her head on another's back. When walking, young lions often touch faces with

older ones, an act of close ties imong members of the group.

About ten years ago when I was an undergraduate in college in New York, I was working as a practice student at my University's Museum of Natural History. One day while I was working at the cash register in the gift shop, I saw an elderly couple come in with a little girl in wheelchair.

As I looked closer at this girl, I saw that she was seated on her chair. I then realized she had no arms or legs, just a head, neck and the trunk of the human body. She was wearing a little white dress with the patterns of red roses and yellow dots.

As the couple wheeled her up to me I was looking down at the register. I turned my head toward the girl and gave her a wink(眨眼示意). As I took the money from her grandparents, I looked back at the girl, who was giving me the most beautiful, largest smile I have ever seen

All of a sudden herhandicap was gone and all I saw was this beautiful girl, whose smile just melted me and almost instantly gave me a completely new sense of what life is all about. I immediately felt full of hope and confidence. She took me, a poor, unhappy college student, into her world, a world of smiles, love and warmth.               

That was ten years ago, but I still remember it clearly as if it happened just yesterday. I'm a successful business person now and whenever I get down and think about the troubles of the world, I think about that little girl and the remarkable lesson about life that she taught me.
