【題目】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 (水平線) 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 (垂直線), 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. Researchers 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.

The man-like robot looks like a small girl. It is four-feet tall with a tablet computer（平板電腦） set to its chest. It has human-like hands, a girl-like body and baby-like voice. It was shown to curious people in Tokyo stores on Friday by Softbank, a Japanese robotics company.

Pepper can examine facial expressions(面部表情)，human voice and signs, then make an answer. Pepper is designed to be a family robot, but it isn’t like Rosie who can do housework on the cartoon. Pepper is used at the home or the store, where we provide fun and entertainment.

Pepper gets power from love inside a family. Not only is he making jokes, makingthem laugh, it can also help people when they are in trouble. In a natural accident, it can help make those people who are sad or lonely feel relaxed, encourage them or make them laugh.

Pepper goes on sale in Japan for around $2,000 in February 2015. For now, several Peppers are at Softbank stores in Tokyo for people to visit. The creators say before selling Peppers, they want the robots to store more knowledge, to do better in gettingalong with human.
