A 13-year-old American has made a cheap machine that can help blind people read.

The blind canreadby using Braille – a system of small bumps (隆起物) that the blind touch to read the letters. The machine that makes these small bumps usually costs at least $2,000. It is called Braille writer. The American schoolboy, Shubham Banerjee, made a new Braille writer from a Lego tool that lets people create robots. Banerjee has called his new machine the Braigo – a combination (组合) of the words Braille and Lego. It costs just $ 350. It works by changing electronic text into Braille and then printing it using a computer or mobile machine.

Banerjee designed (设计) his Braigo last year for a school science exhibition. Since then, he has caught the interest of Silicon Valley in the USA. The big technology company Intel spent money on Banerjee's machine last November, but they did not say how much money they put in. Banerjee also got $35, 000 from his father to help him start the project. His father works as a computer engineer (工程师) at Intel. He spoke about why he gave so much money to his son, saying:”We as parents started to be interested more, thinking that he's on to something and this invention has to continue.” Banerjee told the AP News: “My dream would probably be having most of the blind people…using my Braigo.”

    A picture of a facial expression soon went hot on China' s social media platform during the 2016 Rio Olympics. Fu Yuanhui, a 1996-born girl ,became the second most popular word on the hot topic list because of her ecstatic(狂喜) reaction to her performance.

    In less than 24hours, Fu has been discussed thousands of times on Weibo, Wechat and other platforms. Her photos have been used as emoticons(符号表情) and in cartoons. Her fans went from 100,000 to over 2.7 million on her Weibo in just two days.

     “I did not reserve my strength. I have tried my best… I am very satisfied with the result and I have never thought about the final,” Fu said in her interview after the semi-final（半决赛）.

    Fu was quite humorous in the interview. She used a phrase called “Hong Huang Zhi Li” to describe the great efforts she had made in preparing for the match, which also became a popular word on the Internet.

     “Hong Huang Zhi Li” means “the strength which can separate the heaven from the earth in the chaotic(混沌的) world of ancient times”. While “Hong Huang” refers to “the chaotic state in the ancient times”, “Li” refers to “strength” in Chinese.

    John likes chocolates(巧克力) very much, but his mother doesn't give him. They're bad for his teeth, she thinks. John has a very nice grandfather. The old man loves John very much and sometimes he buys John some chocolates. Then his mother let him eat them. Because she wants to make the old man happy.

    One Sunday evening before his seventh birthday, he shouts, "Please, God(上帝), let them give me a big box of chocolates for my birthday." His mother says, "God can't hear you. Don't shout (叫喊)!"

    "I know," says the clever boy with a smile. "But my grandfather is in the next room. And he can."

    How funny would it be to see memes(表情包) in our textbooks? Fourteen high school students from Sichuan Province have made this a reality.

    They wrote a set of creative textbooks that includes five subjects: Chinese, English, Maths, Chemistry and Physics. They share their notes and experiences to help you prepare for high school entrance exams. You can see funny memes almost everywhere in their textbooks. The language they use is not too serious.

    Each textbook has its own highlights(亮点), too. The English textbook introduces tongue twisters(绕口令), movies and TV series. The chemistry textbook has wuxia characters. There is a boy named Shangguan Huaxue(chemistry) in the book. He meets a girl and they learn chemistry together. It has ancient poems and wuxia-style descriptions.

    Yan Zuhuai, 15, a top student from Chengdu No.7 High School, is the textbooks' editor-in-chef. He got the idea to create the books in June. "Many underclassmen wanted me to share my notes with them. When I saw people sharing bikes, I thought, why not share knowledge as well?" Yan said.

    But when he put all of his notes together, he found that they were boring. Realizing that his classmates enjoy online novels and memes, he decided to add these things. He wrote guidelines and samples for each textbook and invited 13 students to join him in creating them.

    Their first drafts(草稿) came out in August. Students and teachers praised them. But Yan felt the books needed to be improved. In October, he and his team learned how to use the design software to improve the books. The final version(版本) will come out at the end of December. About 2,500 people have preordered (预订) them. Many publishing houses have shown great interest in them. 

    Hi, I'm Tina. I'm a student in Grade One. I have a twin brother, and his name is Tom. We are in the same class. We go to school together every day and we know each other very well.

    Tom likes music very much, and he likes JJ Lin's songs best. He wants to be a singer like him when he grows up (长大). After dinner, Tom tells me he wants to go to JJ Lin's concert tomorrow, but we have lessons. So he calls our teacher Mrs. Green on the phone.

    "Hello, Mrs. Green," Tom says, "Tom is ill and needs to stay at home tomorrow." "I'm sorry to hear that," says Mrs. Green. "Who is that?"

    "This is my mother, Mrs. Green."
