—John is in a difficult        now. So we should help him.

    Lion was the King of the Jungle(灌木丛). One day, Giraffe told Lion, "Rabbit says he is the new King of the Jungle." "What?" Lion was very angry. He went to meet Rabbit. The other animals followed him to see what he would do. "Rabbit," said Lion, "Why do you say that you are the new King of the Jungle?" "Oh, but it's true," said Rabbit. "I'm faster and cleverer than you. We can have a competition（竞赛）.""All right," said Lion.

    Rabbit took Lion to a deep ravine (深谷). He said, "If I fly down to the ravine faster than you, I am faster and cleverer than you. So I go, or you will go first?" "Of course I will go first," said Lion, "I am the King of the Jungle!" He then threw himself into the deep ravine. Rabbit smiled and said to the other animals. "I am your new king now. I am faster and cleverer than Lion." The other animals didn't understand.

    "Lion was stupid! Anyone will die after jumping into the ravine!"

—It's 100 grams.

    Can dolphins talk? Maybe they can't talk with words, but they talk with sounds. They show their feelings with sounds. Dolphins travel in a group. We call a group of fish “a school(一群).” They don't study, but they travel together. Dolphins are mammals(哺乳动物)，not fish, but they swim together like fish in a school.

    Dolphins talk to the other dolphins in the school. They give information. They tell when they are happy or sad or afraid. They say” welcome” when a dolphin comes back to the school. They talk when they play. They make a few sounds above water. They make many more sounds under water. People cannot hear these sounds because they are very, very high. Scientists make tapes of the sounds and study them.

    Sometimes people catch a dolphin for a large aquarium(水族馆). People can watch the dolphins in a show. Dolphins don't like to be away from their school in an aquarium. They are sad and lonely. There are many stories about dolphins. They help people. Sometimes they save somebody's life. Dolphins' meat is good, but people don't like to kill them. They say that dolphins bring good luck. Many people believe this.
