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.

 The 14-year-old girl Susan Davis is having a party. At this party, there are neither cakes nor candles. There is only a room full of art supplies(供应品)and many kids she never met. And all the kids are homeless.

 Susan got the idea last year after her school. She worried that kids who could not afford their own supplies would give up drawing. So she started writing letters to big companies to ask for help. Then the girl received lots of donations(赠品)from some of the biggest art supply companies. Susan collected more than $3000 in supplies, enough to make a home for kids to paint their own watercolors.

By far she's held three parties. What she did was encouraged by the White House. Susan received the President's awards(奖赏). Now Susan does it for a different reason— to get the poor kids to enjoy art.

    Is there a connection between music and language? According to recent studies, the answer is yes: {#blank#}1{#/blank#}Here, we look at two examples

    A recent study by researcher Kraus shows that playing a musical instrument can improve a person's hearing ability.{#blank#}2{#/blank#}The people in the first group were musicians, while those in the second group had no musical training. The musicians were able to hear the talking person more clearly.

    {#blank#}3{#/blank#}Think about violinists in an orchestra (管弦乐团). When the violinists play with the group, they hear their own instrument and many others, too. But the violinists must listen closely to what they are playing, and pay no attention to the other sounds. In this way, musicians are able to focus on certain sounds, even in a room with lots of noise.

    Schlaug, a doctor at Harvard Medical School, works with stroke (中风) patients. Because of their illness, these people cannot say their names, addresses, or other information normally. However, they can still sing.{#blank#}4{#/blank#}Why does this work? Schlaug isn't sure. Music seems to make different parts of the brain work, including the damaged (损坏的) parts. This might help patients to use that part of the brain again.

    Music improves concentration (注意力), memory, listening skills, and our overall language abilities.{#blank#}5{#/blank#}Playing an instrument or singing can help us do better in school and keep our brain sharp (敏锐的) as we get older. Music is not only enjoyable, it's also good for us in many other ways.

    Why do people cry? Scientists say the body produces tears because they need them. One kind of tears is for the eye, the other is for the heart. They both work as cleaners. If something else like dust(灰尘) gets into your eye, tears also come into the eye to clean it out. If you are hurt by something, your strong feelings produce some poisonous chemicals(毒素) in your body, and at the same time, tears come out with them. If these poisonous chemicals are not cleaned out of your body as soon as possible, they will do harm to the heart sooner or later.

    In the United States men have heart problems more often than women do. Doctors say heart problems have something to do with the pressures(压力) of living and working now. Perhaps men suffer more from these illnesses because they do not cry enough. They need to cry more.

    In fact, you can find many ways of reducing the pressures to keep fit. Crying is a natural and physical one.
