Joao, 71, lives on an island near Rio de Janeiro, Brazil. He doesn’t need to work, but still works as a part-time fisherman. One day, about five years ago, when he was walking on the beach, he saw a little penguin with oil (油) on its body. “If no one helps the bird wash away the oil, it may lose its life,” Joao thought. So he took the bird home and gave it a shower. Joao gave the bird fish to eat, and called it “Din dim”. The penguin soon became strong and healthy. It was able to go back to the water.
After a week or two, Joao went down to the coast (海岸) and tried to free Din dim. But the penguin didn’t want to go. It stayed with Joao for another eight months, getting bigger and stronger. And Joao enjoyed being with his new friend. Then one day in February, Din dim left. When Joao found this, he cried and couldn’t eat or sleep all day and all night. But, in his heart, he hoped that the bird went back to its penguin family. Four months later, when Joao was walking home from the beach, he heard a “honking” sound—Din dim was back. Joao ran to it, and Din dim touched Joao’s face, helping clean his tears (眼泪).
Later, Din dim goes back and stays with Joao every year. Where does it go In fact, it swims about 2,500 miles to the coast of Argentina or Chile to start a penguin family and then swims back to Joao. It swims about 5,000 miles a year to be with the man who saved its life. The penguin thinks that Joao is part of its family.
26．Why did Joao take Din dim home at first

Last weekend, my family and I visited City Zoo. It was my first time to see so many animals. As soon as we entered, we saw giraffes eating leaves from tall trees. Their long necks helped them reach the highest branches easily. Then we watched a penguin show. The penguins looked so cute in their black-and-white “jackets”. They swam quickly in the water, just like excellent swimmers.
But what made me sad was the “Save the Sharks” sign. A zookeeper told us many sharks were killed for their fins (鳍) every year.
