The story of Pippi and Bibi

1. Once upon a time, there were two puppies, one named Pippi and the other named Bibi. Pippi is very serious in class, and Bibi is very playful in class. One day they met.

2. One day, Pippi went down to buy candy, and Bibi also went to buy candy. Coincidentally, they met in a candy store at the same time. Pippi said, "It's interesting that you are so short and come to buy sugar." "I should tell you this." Two puppies are on their high horse. Pippi has a brainwave and Bibi says, "Do you dare to compete with me?" "Let's compare, who is afraid of who!" Bibi shouted, and then they ran to the nearby haha mirror.

Pippi knows that concave lens can make him bigger and convex lens can make him smaller, so there is no doubt that Pippi stands in front of concave lens and Bibi stands in front of convex lens. Pippi was glad to see that his body was almost twice as big as the original one. When he looked at Bibi, he found that his little body was not as big as a mouse. Bibi also looked up at Pipi. He was frightened and ran away.

Another day, Bibi went out for a walk and met Pippi again, trembling with fear. He only hates his parents for not giving him more legs. Bibi said, "Who are you? I didn't know you, so I ran away. " Haha, Bibi is so timid, Pipi said with a smile.

We should study hard and don't be confused by the surface like Bibi.
