From a large elephant to a small mouse, animals live happily together in Disney's new movie Zootopia. Judy Hopps, the main character, becomes the first rabbit police officer in the city. While solving a mystery, she meets the smart fox, Nick, who helps her with her case（案件）, and some other animals like the lion mayor（市长）and a mouse called Flash. Here is something more about the movie.

    There are 61 kinds of animals in the movie. All of them look like real ones except Judy, the first rabbit police officer. Its appearance is a bit different from real rabbits. Real rabbits actually have split lips（嘴唇）, but the film makers decided to make Judy's lip all together to look nice.

    Film makers learned that not all fur（皮毛）of animals is the same. In the movie, some of polar bears' fur is clear. It appears white because the light reflects off it. Part of a fox's fur is dark at the root, getting lighter till its red top. They did so to make sure that the animals in Zootopia were believable.

    Moreover, a film maker, Nathan Warner with his partners also took a trip to Africa for researching animals. There they had a close watching of different animals. According to their discovery, these artists added leaves to animals' coats like the big sheep. They also made animals' tears run from the inside corners of eyes down to the outside of the mouths.

    A Chinese song could be heard in a classroom in Sana, the capital of Yemen(也门), where around 20 Chinese-learning schoolchildren were singing

    "I love to learn the Chinese language because it is very nice, important and I want to travel to China to complete my studies there," Karim al-Areqi, a student of the private Languages Model School in Sanaa, told Xinhua.

    Teacher Mohammed al-Ansi, who learnt the language in China and received a university degree, stressed(强调）the importance of learning the Chinese language. "It is the language of the future and it is necessary for all people to get advantages from the great development in China," he said.

    Like many other private elementary and secondary schools in Yemen, the Chinese language is a basic part of the Languages Model School's courses, where the students study Chinese as actively as math and science subjects. "In teaching the Chinese language, I succeeded in educating students in a simple way that fits everyone," al-Ansi said proudly, stressing that teaching Chinese has changed his life without doubt.

    Al-Ansi expects that Yemen and China will work together to set up centers and schools for teaching the Chinese language in Yemen so that many young Yemenis can learn. "I hope that a branch of the Confucius (孔子学院),could be built in Yemen to teach the language and spread the Chinese culture to many years who are interested in learning the Chinese culture and language," he said. see that learning a foreign language may open a way of hope to a new life, such as getting ,more money and paving(铺平)the way to a bright future in the country that has experienced war for almost five years,

Reporter: Today, we invite May to share her experience of learning Spanish. May, when did you begin to learn Spanish? Why?

May: I started learning Spanish when I was six with the help of my mum. I chose to learn Spanish because I wished to become a doctor in Spain in the future. Learning Spanish allows me to help patients better.

Reporter: Is there anything surprising when you learn Spanish?

May: Yes, of course. At first, I didn't expect Spanish would be easy for me. But then I found there were some similarities (相似处)between English and Spanish. Some words in both languages have the same meaning and pronunciation. Putting those two languages together makes it much easier for me to learn Spanish.

Reporter: What's the best way of learning a language? Can you share it?

: May: The best way is speaking. You don't have to spend hours practising. But speaking some words in Spanish in my life helps me remember things easier and keep the language in mind.

Reporter: Do you have any other advice for those who start to learn a new language?

May: Taking detailed notes is also a great way. I write Spanish with a black pen and English with a red pen. That helps me understand it faster and better.

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!
