The roots of rock and roll' go back to many different countries, many different kinds of music and many musicians. It is difficult to say how the music began.

    Rock music developed mainly from black African and white European music. The Europeans and the African slaves (奴隶) came to America during the seventeenth century. The each had their own music. Black Africans used heavy drumbeats, a singing voice, the calling of a melody and answer of a chorus. The white Europeans, mostly English and Scots, used a stronger melody, a less heavy beat and instruments such as guitars and horns. From the seventeenth to the twentieth century, musicians in the United States developed two new forms of music; the blues (蓝调音乐) , usually played by blacks, and country music, played by whites. Black musicians sang the blues with a guitar. This music was work songs: stories of troubles and pain, with lines that were repeated several times.

    The word 'rock and roll' probably came from the black churches in the South, where people sang and danced to the strong rhythms. At the same time, whites were playing country music. They went on with their of dancing music and slow songs that told sad stories. The singers played with string instruments such as fiddles and guitars.

    During this time blues and country musicians had some on each other. The birth of the electric guitar changed country and blue music in the 1940s. The sound of the electric guitar became the sound of rock and roll. No one thinks of early rock and roll without thinking of Elvis Presley (埃维斯·普利斯里，美国著名摇滚明星), the 'King of Rock and Roll'. Rock music to develop, but the heart and soul of rock is the same heart and soul that Elvis_ .

Mike wondered they managed to get everything finished so quickly.

    On March 10, 2019, eight-year old Tani won the New York Chess Championship of his age group. But the boy, who was homeless at the time, began learning the game less than a year ago.

    Tani and his family arrived in New York City from African in 2017. A church helped him enter the primary school, P. S. 116. Here the gifted boy was first introduced to chess by a teacher Makofsky, owner of a chess club. Interested in the game, the seven-year-old boy asked him mother to allow him to join the club. As she wasn't able to afford the chess classes, she e-mailed Makofsky. To her surprise and joy, Makofsky agreed that Tani could lean it or free.

    Though the chess club helps, it's largely believed that Tani's success lies in his hard work. The boy practices the game for many hours a day on the floor with his board. Every Saturday, Tani goes to a free 3-hour class to improve his game skills.

    Not surprisingly, Tani's story, first reported by the New York Times, has brought him great support from the American public. Soon after the young boy won the New York Champion ship, Makofsky began a GofindMe activity for Tani and his family. In this way, Tani could continue his chess journey. It raised $ 200,000 in just ten days, far more than they expected. And the money goes on coming. But the family donates most of the money to the church and to those poor families.

    Tani has also got offers from three famous private schools in New York. However, the family have politely rejected all of them and chosen to continue Tani's education at P. S.116.

    The young boy's story also caught the eye of Bill Clinton, the 42nd US President."Tani, you're an example of a winning spirit—in chess and in life. I'd love to meet you. 'He said on his Facebook.

    While Tani is excited about his new life, he is ready to meet great challenges. He is busy preparing for the next National Primary Championships. Winning the competition will bring the chess player closer to his dream of becoming the world's youngest chess grandmaster (最高段的棋手). The record has been kept for 17 years by the Russian chess player Karjakin, who won the title at the age of 12. .

The Digital Black Hole

    Libraries around the world still hold copies of books printed hundreds of years ago. Will e-books still be read by us in hundreds of years' time? Librarians are1the fact that digital information and digital books are disappearing. Technology is always changing, and even now, we cannot get information typed in programs we used ten or fifteen years ago. Is digital data in danger of disappearing into a digital black hole?

Amazingly, we still have copies of the first collection of William Shakespeare's 36 plays (威廉·莎士比亚的36部戏剧), The First Folio. That's not bad for a book that's nearly 500 years old. The Folio was2in 1623. Around 800 copies were printed and 234 known copies still survive today.

    Books are easy to store and we don't use any special equipment to read them. But what about the documents (文件) kept on your computer now? Will people be able to read them in 800,500 or even 10 years' time? Documents we stored on discs (磁盘) ten or twenty years ago can't be3on our 21st century laptops. What about all your digital photograph? Every second, thousands of them are uploaded to social media. What will happen to them? Will they be lost in a few years' time?

    Music is in danger of being lost, too, we have to think of new ways to store it. We must copy this music or find the best way of storing it for future generations.

    When a website closes down, all the information on it is deleted. It's gone4. It was disappeared into the ‘digital black hole' Organizations have understood this problem. In 2004, the British Library started to keep important websites for future generations, just like paper-based literature. In the event of a digital black hole, it could all disappear. The only5is to print it all out and keep physical copies.

    With all the amazing new digital technology available to us today, we still have to rely on the centuries-old technology of printing. For now, printed copies are still the6way to store information.

    Shirley's Helsinki Happiness

    Doctors have told Shirley Williams that she will be able to compete in the European Championships in Helsinki next month. The 28-year-old boxer had a complete hand operation after being involved in a car accident. Doctors once told her that her career was over. But a two-year intensive recovery programme means that she now is well and has the chance again. 'I never thought this day would arrive,' she told reporters. 'After Helsinki I'm going to start t for Lima 2044', she added.

    George Reeder, 63, in Somerset has been given a bravery certificate (证书) for saving the life of a baby boy.

    It was a cold and windy morning. The local harbour master, George Reeder, was carrying out his regular duties when he heard a noise that caught his attention. On the other side of the harbour, some people were pointing and shouting, so he cycled over quickly

    Mr Reeder expected to see a dog in the sea, bu instead, he saw a baby's buggy (婴儿车) in about four metres of freezing cold water. A woman was screaming desperately - her baby boy was trapped into the buggy and was in the water. The strong wind had blown the buggy into the sea. Mr Reeder quickly decided to do something.

    "I went over and saw that the buggy was upside - down ... and I jumped in," said Mr Reeder. He pulled the buggy over to the sea wall. Then some other people came to help. They tired a rope to the buggy and managed to pull it out of the water and to safety.

    Tanya Allen, a passer - by (who, fortunately, was a nurse), gave the baby CPR (心肺复苏术) and was able to get him to breathe again. Mr Reeder remembered seeing a little bit of breath coming out of the baby's mouth. 'I thought, he is all right. He's alive. Brilliant!" he said. Then an air ambulance helicopter arrived and the baby was taken to hospital. Mr Reeder said it was unbelievable that baby survived. 'It's such a miracle,' Mr Reeder added.

    After he'd finished helping the baby and the helicopter had gone, Mr Reeder went home to recover from the experience. The child's grandfather knew Mr Reeder and, a little later, went to his house to tell him that the boy was out of danger. Mr Reeder was very relieved and happy to hear that.

    Mr Reeder said that he hadn't really been brave. 'It was everyone - from Tanya doing the CPR to the helicopter pilot,' he said. 'I'm just glad I could help. But when Mr Reeder got the certificate, a reporter said that what he'd done was very brave. 'This was an extremely brave act, as he put his own life at risk.' The reporter has advised local people to avoid walking along the seafront in very windy weather.
