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.

    In Sydney, Australia, there lived a man called Mark Simon. Mark enjoyed betting so much that he would bet on anything. One day, Mark showed a frog to a stranger. He bet the stranger $60 that the frog could jump farther and faster than any other one in Sydney. The stranger said he would bet Mark if he had a frog. Mark left his frog with the stranger and went to find a frog for the stranger. The stranger opened the frog's mouth and put a bag of sand into it Soon Mark came back with a frog for the stranger. The two frogs were put on the floor and given a push. To Mark's surprise, the stranger's frog jumped off smartly but his frog just sat there. Mark had to give $60 to the stranger. After the stranger left, Mark picked up the frog, and found it quite heavy. He turned it upside down, and the bag of sand came out He knew he had been fooled and started running after the stranger.

    Today taxis are very common in cities all around the world. While London is world- famous for its special back taxis, New York's yellow taxis are also well- known all over the world. How about the taxis in Mumbai, India? Before a project (项目)named Taxi Fabric, taxis got little public attention. But now things are different because some of them have changed their common looks. Artist Sanket Avlani started the project last year with some other artists. He said," Taxi drivers here try hard to decorate(装饰）their taxis and make them stand out from others, but they usually pay little attention to the insides of their taxis. "He hopes to use his art project to connect young designers(设计师）with taxi drivers." The designs that cover the taxi seats are often boring and forgettable ,but they can be improved with the help of designers in Mumbai.

    Last summer the project raised over £l1, 000, and they invited local designers to create different designs inside the taxis. All the designs are about Mumbai. The designers are local but they got their ideas from all around the world. So far they've created 26 different designs, which make the insides of Mumbai's taxis as colorful as the views from their windows. Taxi Fabric is now hoping to spread to other cities in India. They are also inviting designers from all over India to take part in the project and planning to redesign buses, trains and subways besides taxis.

    We did a survey (调查) about students' free time activities yesterday. One of our questions was about exercise and of course, it is the most important one. From the survey, we knew only 25% of the girls often have activities outside. Many girls do little exercise. They don't like P.E. classes and even don't play sports. These girls may face a lot of problems. They may get fatter and weaker, And they may get some kinds of illnesses(疾病) easily. Wang Jing, a 16-year-old girl, said, "I don't like doing exercise. I like watching TV on the sofa. I spend at least three hours watching TV a day. My sleeping time is no more than seven hours a day. I often feel tired

    Some girls said, "We don't have enough time to do exercise. We must help our parents with housework because they are very tired after a day's work. We do some washing, clean the house and finish the homework. We don't have time for doing anything else."

    Everyone may have these excuses(借口) for not doing exercise. However, we must know that if we don't do exercise, we will get sick easily. As students, we'd better exercise every day. That makes us live a healthy life.
