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.

    Do you like eating chocolate chip cookie？Thanks to Ruth Wakefield, they were invented by accident in 1930.

    Ruth and her husband owned a restaurant called the Toll House. As manager and cook, Ruth kept very busy. One day in 1930, she was making some chocolate butter cookies．It was required that she should melt chocolate into the dough (面团)．However, she found that she had run out of baker's chocolate. So she had to break some semi­sweet chocolate (半甜巧克力) into small pieces and added them to the dough. She hoped these pieces of chocolate to melt.

    After the cookies were baked (烤), to her surprise, the chocolate had not melted into the dough, and her cookies were not chocolate butter cookies. They smelt delicious. They tasted sweet and crispy．

    They were named Toll House cookies after Ruth's restaurant and are the most popular cookies in America today. About seven billion chocolate chip cookies are eaten every year, and nearly half the cookies baked in American homes are chocolate chip cookies.

    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.

    Coral reefs(珊瑚礁) are found in warm ocean(海洋）waters all over the world. Coral reefs are important because they are home to many ocean plants and animals. They also help keep the sea clean. As well, they provide（提供）food, jobs and a special place to visit for millions of people all over the world.

    There are three main kinds of coral reefs: fringing reefs, barrier reefs and coral atolls. Coral reefs are formed（形成）by tiny animals called coral polyps.

    When coral reefs are healthy, they keep the ocean environment balanced. But many things that humans do are making the reefs sick. Some reefs are even starting to die.

    We should protect coral reefs and help them become healthy again.
