Have you ever had the feeling that no one can understand you? Well, here comes “Pepper”, it could be about to change all that. Pepper is the first robot to read human feelings. Using its emotion recognition functions(情感识别功能), Pepper can make jokes, dance and even sing to people when they are around it.

 The robot looks like a lovely girl. It is four feet tall with a tablet computer in its chest. It has human-like hands, a girl-like body and baby-like voice. It was shown to attract people at stores on Friday.

Pepper can tell facial expressions, human voice and signs, then make an answer. Pepper is designed to be a family robot, but it isn't like the household robot on the cartoon. Pepper is used at home or store, where we enjoy pleasure and entertainment.

 At home, not only can it tell jokes, it also helps people in trouble. If a natural accident happens, it can encourage them, make them laugh and feel relaxed.

 Pepper will be on sale at the price of $2,000 in August, 2015. At present, several Peppers are on show at stores for people to visit. Before selling Peppers, the creators want them to store more knowledge in order to get better along with human beings.

    Fire was discovered many thousands of years ago. The first time humans saw fire was probably when a tree was destroyed by lightning(闪电).Humans soon learned how to make a fire. They probably made the first fire by rubbing (摩擦)two sticks together. Fire was very important to humans. They needed fire to keep warm at night. They used fire to cook food. ⑶They used fire to keep enemies and wild animals away. In some parts of the world fire was used to send messages. The Indians in America, for example, used fire to make smoke as a message. In some other countries people lit fires to warn their friends of danger. ⑷Fire was also used to give light. Before the invention of the oil lamp(灯), humans burned sticks to get light. One man even used fire to tell the time. He invented a candle clock. He made a candle that took exactly twelve hours to burn. Then he marked this candle in twelve equal(相等的) parts. He lit the candle and could tell the time by counting the number of parts left of the burning candle. But the candle clock did not always work well. If there was a wind blowing on the candle, it burned too quickly.

    Samuel Langhorne Clemens was born in 1835, in the state of Missouri. When he was four, his family moved to the town of Hannibal, Missouri. Hannibal was a port on the Missippi River, and Clemens loved to watch the big steamboats going up and down the river. He said that all the boys in his school had one ambition in life: to work on a steamboat!

    His father died when he was just 12 years old, and Clemens then went to work for a printer to help support his family. He travelled around, and worked in many different cities. But when he was 22, he achieved his ambition—he got a job working on a steamboat. He sailed up and down the wide Missippi River until the American Civil War began.

    He then moved around America, and tried several jobs. He was a soldier, and a silver miner. Then he started working as a writer for a newspaper. It was at that time that he decided to use a pen name for his stories, and he chose the name "Mark Twain".

    The name is interesting. It comes from his days on the steamboats. He used to throw a piece of rope into the river. There was a heavy weight on the end of the rope, and the rope had some marks on it. He used the rope to find how deep the river was. Then he shouted out, "Mark One" or "Mark Twain", meaning "Mark Two". Each mark was about two metres, so when he shouted "Mark Twain", it meant that the river was deep enough for the big boat.

    In 1865 Clemens wrote a story about a jumping frog. The story and the writer became famous. In 1867 he toured Europe. He married when he returned, and lived for most of the rest of his in Harfort, Connecticut. He wrote many books, including The Adventures of Tom Sawyer, which he wrote in 1876. He also gave many lectures, and became a very famous and popular man.

    Once two of his friends decided to write to him, but they had lost his address. So on the envelope they just wrote "Mark Twain, God knows where". Several weeks later, they received a replay from the writer. It just said, "He does!"

    Samuel Clemens died in 1910. He is considered to be one of America's most important writers.
