Many animals around us are smart. Let’s get to know some of them.

Dolphins are smarter animals in the sea. Researchers put sea animals to a test. In the test, the researchers made red marks on the animal’s bodies and took them in front of a mirror. Many sea animals either ran away or fought with the ones in the mirror. However, when the dolphins saw themselves in the mirror, they tried to clean the red marks off their bodies. So the researchers believed that the dolphins knew the ones in the mirror were just themselves.

Bees work hard, and they are smart enough to learn something. Researchers found a group of bees and taught them to tell which horizontal line(水平线) was higher than the other. If they could find the higher line, they would get sugar as a prize. After training for a period of time, the researchers tested the bees. To their surprise, the bees found the higher horizontal line quickly and got sugar. Instead, when the researchers showed them vertical lines(垂直线), the bees simply flew away, because they knew there was no way to get sugar.

Chimpanzees(黑猩猩) are very human-like. They can learn fast and well. Researcher showed the numbers from one to nine on the screen. Chimpanzees and some college students were asked to remember where the numbers were after watching the numbers in less than a second. The adult chimpanzees and the college students performed almost the same, but the young chimpanzees performed much better. It was amazing.

Just like we have neighbors, countries also have neighbors. For us here in China, India is one of our neighbors. Now let’s learn more about this amazing country.

India is one of the four oldest civilizations（文明）in the world. About 5,000 years ago, Indian civilization was born. Today, with a population of over 1.2 billion, India is the world’s second most populous country behind China.

Its great civilization makes the country exciting. The world’s highest mountain, the Himalayas, rises in the north. The mountain is home to some of India’s rarest（最珍稀的）animals.

Also, India is known for making software（软件）. IT products（产品）from India are commonly used. If you have a mobile phone, some of the parts may come from India.

Many Indians work for IT companies in Bangalore, also called the Silicon Valley（硅谷）of India. It is the country’s software production center.

If you are not interested in software, then India’s modern culture（现代文化）may excite you. Most Indian films are called Bollywood films. Many of them tell stories with a lot of lively music and dancing. They usually have a happy ending. For example, 3 Idiots（《三傻大闹宝莱坞》）is one of the best ones.
