More than anything else in the world,Lion liked being King of the jungle.He walked around,showing off his power and pride.

Each day Lion took a long lazy sleep under the shade of his favourite tree.He always dreamed of weaker animals bowing(鞠躬) before him.

One day Mouse ran through the jungle and tripped over Lion's huge paws.Lion woke up with a start."How dare you wake me up!"he shouted angrily.Lion grabbed Mouse with one paw."On the second thought,I'm in the mood for the snack,and you'll make a delicious meal.",he said.

Mouse cried out,"King Lion,please spare(饶恕) me!If you let me live,I'll always remember your kindness.And,some day,I might be able to help you."

"How could such a powerless little mouse ever help me?"That thought made Lion laugh so much that he decided to let Mouse go.A week later,Lion was walking through the jungle on the way to his favourite tree when he stepped onto a hunter's net.The net scooped him up.No matter how he twisted and turned,he couldn't escape.

When Mouse heard Lion's frightened shouts,he raced to help.Mouse quickly chewed(咬)through the ropes to make a hole in the net.Soon,Lion moved out and was free.Lion looked down at the little mouse."Thank you for saving my life,"said Lion,smiling his widest smile."I was mistaken.You are not a powerless little mouse.You are a great friend!"

5-second rule:what’s the truth?

Almost everyone has dropped some food on the floor and still wanted to eat it. If someone saw you drop it, he or she might have shouted, “5-second rule!”This so-called rule says food is OK to eat if you pick it up in five seconds or less. But is that true?

Professor Anthony Hilton from Ashton University, UK, tested the rule with his students. They found that food dropped for five seconds is less likely to contain bacteria(细菌) than if it sits there for longer.

For the study, Hilton and his students tested a lot of food—bread, pasta, cookies and candy—to see how much bacteria they had when they made contact with the floor. They allowed the food to lie on various types of flooring-carpet, laminate(复合地板), and tile (瓷砖) for three seconds to 30 seconds.

Not surprisingly, the longer the food was on the floor, the more bacteria it had. And the type of floor where the dropped food landed had an effect. Bacteria are least likely to transfer from carpet, while they’re most likely to transfer from laminate or tiled surfaces after more than five seconds.

The study also found that the wetter the food, the more likely it was to pick up bacteria. Although most people are happy to follow the 5-second rule, eating food dropped on the floor still carried an infection(感染) risk. “It very much depends on which bacteria are on the floor at the time,” Hilton told Forbes.
