Roger is new in town, and it has been hard to make friends. The kids at school are nice, but Roger is shy. His birthday is coming up soon. He is planning a big party. It will be a lot of fun. There will be cake, and ice cream, and a treasure hunt(寻宝游戏). But what if none of the other kids want to come?

    One week before his party, Roger and his dad go to their favorite restaurant. Benny's Pizza Parlor makes the best pizza in town. Roger orders a large pizza, with four kinds of cheese and extra pepperoni (意大利香肠). He loves every bite. When he is finished, Roger and his dad go to the kitchen to talk to Benny.

"How was the pizza?" Benny asks.

    "It was great!" says Roger.

    "Thank you!" says Benny.

    Suddenly, Roger gets a great idea. "Benny," he says. "Will you cook pizza for my birthday party?"

    "Hold on, Roger," says Roger's dad. "Benny is very busy. He might not have time to make pizza for your party." "But everyone loves his pizza!" says Roger. "If we have it, I'll be the most popular boy in school."

    "I know what to do," says Benny. "I won't cook pizza for your party. Instead, I'll show you how to make it yourself!" That week, Roger goes to Benny's Pizza Parlor every day after school. Benny shows him how to make pizza and he tries his best.

    Roger tells the kids at school that his party will have pizza from Benny's. Everyone is excited. Everyone loves Benny's pizza. But when they come to his house, Benny isn't there. Instead, they see Roger, wearing an apron(围裙) and a chef's hat. The kids don't believe that Roger knows how to make pizza. However, he's ready to prove them wrong. Roger makes them his favorite pizza, with four kinds of cheese, and extra pepperoni. Everyone says the pizza tastes just like Benny's. It might even be just a little bit better.

Smart, Social Animals

Recently, researchers have found that dolphins know their own names much like people. Dolphins talk to one another with whistles (口哨) and calls. Scientists have known that the animals also use unusual whistles to name each other. They had thought that dolphins only heard each other's voices. However, the scientists didn't know that dolphins listen for their names too. 

To test this idea, the researchers caught 14 dolphins and recorded their name calls. The scientists then copied each dolphin's voice. When the changed recordings were played, the dolphins replied strongly to the names of their relatives and close group members. They paid no attention to the names of dolphins they did not know. 

Dolphins live in large groups that grow and change. Each dolphin's unusual whistle helps it quickly find a friend or a family member, or call for help. Understanding their calls requires learning. It's a skill that's seen in very few animals, which include humans, elephants and bats. 

Elephants, for example, communicate with sounds. Their sounds can be heard by other elephants miles away. Dolphins, too, communicate with each other by making sounds like this. 

Elephants also communicate by moving their head, feet and trunk. In much the same way, dolphins communicate through their movements. They often touch each other to express friendship. 

Unlike dolphins, elephants also communicate through their great sense of smell. They can recognize other elephants through the smells they have. 

Why do dolphins and elephants share the gift of communication? Scientists think it may be because they are social and smart animals. Both have strong family relationship. Now, whether they also have nicknames is another question!

One sunny morning, Fern saw her dad with an ax. She asked her mom what was going on. Her mom told her that a baby pig was born very small and weak, and her dad planned to kill it. Fern felt sad and ran to her dad. She asked him not to kill the little pig. She said it wasn't fair to end its life just because it was small.

Her dad listened to Fern's words and saw how much she cared. He decided to let her keep the pig. Fern was so happy! She named the pig Wilbur and promised to look after him. From then on, Wilbur was part of Fern's family, and they loved each other very much.
