The famous scientist and thinker, Charles Darwin, was born on February 12, 1809. As a boy, Charles liked to go for walks in the fields and forests. He enjoyed watching nature, and comparing what he saw with everything he had read in science books.

    At sixteen, Darwin was sent to Edinburgh University to become a doctor. But he was interested in the history of nature. Then he was sent to study in Cambridge University. He left the university in 1831. Some time later he heard that the ship Beagle was going on a trip to South America and wanted a scientist. His teacher advised him to go. So when the Beagle left England in December, 1831, Darwin was on it. The trip lasted almost five years.

    In 1842 Darwin went to live in Ken. Darwin understood that plants and animals are not always the same, and that they really change. By 1859 Darwin had finished his famous book "The Origin of Species". Darwin continued his studies in science before he died in 1882.

    Julie is ten years old. Her brother Rick is eleven. Last year their family went to Kenya (肯尼亚) for their summer holiday.

    They had a wonderful time. Kenya is famous for its safari holiday.

    On a safari holiday, you stay in a national park and watch the wild animals. Julie's family did this. They camped in the middle of a national park, far from any towns.

    There were guides with them, and the guides knew a lot about wild animals. During the day, their guides took them in a big car and they saw all kinds of animals. They saw lions, elephants monkeys and many other wild animals. Sometimes the animals came very close to them. Once an elephant started to walk towards them, and Julie and Rick felt very scared. The guide said, "It's all right. Don't move, please." He didn't seem afraid at all! After some minutes, the elephant walked away.

    At night, the family slept in a tent. They could hear the noises of the animals. They said it was noisy, and sometimes they couldn't sleep! Also, they said it was very, very hot. But they loved their holiday and are going again next year.

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 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 and elephants.

Elephants, for example, communicate with sound. 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 (象鼻). In much the same way, dolphins communicate by their movements. They often touch each other to express friendship.

Unlike dolphins, elephants also communicate by their great sense of smell. They can recognize other elephants by 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(绰号) is another question!

In the Bay Area in California, you can find many amusement parks with fun rides.
