California has become the first U.S. state to approve plans to require newly-built homes to include solar equipment.

    The state's Energy Commission voted 5-0 to approve the new rules, which are to take effect in 2020. The rules will deal with most newly-built residential (住宅的) buildings up to three stories high.

    The move is California's latest step aimed at reaching renewable energy targets and reducing greenhouse gas emissions.

    California has set a goal of filling half of its electricity needs with renewable energy by 2030. Officials said they had reached 30 percent by the end of 2017. The state's Governor, Jerry Brown, plans to hold an international climate meeting in September.

    ①The Energy Commission said the cost of adding solar equipment to a single-family home would be about $9,500. But, the group added that homeowners would save at least $19,000 in energy costs over 30 years.

    Robert Raymer is the technical director for the California Building Industry Association. He says the action is a step forward for the wider use of solar power in the U.S. "You can bet every other of the 49 states will be watching closely to see what happens," he told the Associated Press.

    ②Solar companies praised the new requirements, which officials have said will likely raise demand for solar equipment in California by 10-15 percent.

    The Solar Energy Industries Association called it a "historic decision for the state and the U.S." It estimated the action would produce "huge economic and environmental benefits," including bringing tens of billions of dollars into California.

    ③Some legislative and community leaders argued that Californians cannot afford to pay any more for housing in what is already an extremely high-priced market.

    "That's just going to drive the cost up and make California, once again, not affordable to live in," said California Assemblyman Brian Dahle.

    ④Severin Borenstein is an energy economist at the University of California, in Berkeley. He sent an email to the head of California's Energy Commission to urge the state to reconsider its decision.

    He expressed his belief that it is a mistake for California to approve such a policy instead of centering on efforts to develop large solar farms to produce renewable energy. He said these farms would cost much less to operate.

    "Every energy economist I know is shaking their head at this," he told the Wall Street Journal. "In many ways, this is setting the wrong example," he added.

    Jack threw the papers on my desk. “Next time you want to change anything, ask me first,” he said. I had changed a long sentence and corrected its grammar — something I thought I was paid to do.

    Several days later, he made me angry again. I went to his office, prepared to lose my job if need be, but not before I let the man know how I felt. “What?” he said nervously.

    Suddenly I knew what I had to do. “Jack, the way you've been treating me is wrong. And it's wrong for me to allow it to continue,” I said. “I want to make you a promise. I will be a friend.” The next day I brought some cakes to Jack's office. Every time I saw Jack in the hall, I smiled at him. After all, that's what friends do.

    One year after our talk, I was told that I had breast cancer . When I was in hospital, my friends tried to find the right words to say, but no one could. The last day of my hospital stay, the door opened and Jack walked over to my bed. “Tulips (郁金香),” he placed some bulbs  beside me and said, “If you plant them when you get home, you'll be there to see them when they come up.” Tears filled my eyes.

    In a moment when I prayed for just the right words, a man with few words said the right thing. After all, that's what friends do. Now, I have seen those tulips push through the soil every spring for over ten years.

    Youth volunteers from Beijing University visited Song tang Hospital, a care clinic for the aged and dying patients, during the second Global Youth Service Day on April 21．

    Thirty student volunteers from the university's School of International Studies sat at the beds of the patients in their specially decorated “care huts”. They talked with them and gave massages （按摩）to patients kept in their beds.

    I felt sorry that I could not offer more to these people than talking with them and trying to cheer them up, said Deng Yetao, 20, a third - year student. “But it occurred to me that they need more care and love than babies. They are afraid of the coming death. Their loneliness is worse than physical pains.”

    “Even though they are suffering a lot, the majority of the elderly people want to talk to us. Each of them has a lot of life experiences and philosophies to share. Instead of doing them a favor, I felt I was gaining a valuable lesson. Said Mao Xiaohua, another third - year student.

    Mao talked with two elderly patients for a whole afternoon. The fact that most of the patients in the 80 - room clinic are aged people with diseases which will lead to death soon made the volunteers' hearts heavy.

    Ninety - one percent of the patients will spend the last days of their lives in the clinic, according to a survey by the hospital.

    Daily visits and services by social workers and youth volunteers are a very important part of their programmer. A total of 330, 000 Beijing students from 119 universities and colleges have visited the hospital. Many continue to offer services in their spare time. Some of them volunteer to hold the hands of dying patients during the last minutes of their lives.

    Yin Hang, a student from Beijing Medical College, said he felt“ the glory of life” as he saw the fading smile on the face of the old man who passed into a deep unconsciousness（昏迷）while he was holding his hands.

Dear Editor,

    I am writing to you about the article in your magazine last month about youth crime. As a teenager myself I found the article rather offensive(冒犯的) as it suggested that the largest part of teenagers get into trouble with the police at some time or another. I can honestly say that I have never committed a crime(犯罪) and as far as I know, neither have any of my friends.

    I don't know where the journalist got his information from or if he did any proper research, but the way he described teenagers gave me the impression that he doesn't actually know many teenagers. Maybe when he was younger he was regularly in trouble with the police and that's where he got his ideas from. If this is true then he shouldn't judge other people from his own behaviour in the past.

    Many teenagers I know always help other people in the community, such as raising money for charity and doing voluntary work. A group of us recently spent an entire Sunday morning picking up litter in our local park. We didn't get paid for it; we just wanted to make it cleaner and safer for everyone, especially as many young children and dog walkers use the park.

    Also, as teenagers, we are far too busy studying for exams and doing homework to be "walking the streets every night, looking for trouble", as your journalist wrote in his article. I have to study after school every night during the week. I do get some free time at the weekend but I like to play football, go cycling or swimming, go to the cinema or have coffee with my friends and have a chance to talk to them. I think you will agree that there is nothing criminal about that.

    As your magazine is aimed at young readers, I think your journalists should be more careful about what they write and they should research their ideas better, or you may find that teenagers stop buying your magazine altogether.

Yours sincerely,

Daniel Browning

    Breakdancing is set to make its first debut (亮相) as an Olympic sport at Paris 2024, Tony Estanguet, head of the Paris organizing committee, said on February 21st. Skateboarding, sport climbing and surfing, which have already been added to the programme for the 2020 Tokyo Olympics, have been invited to return in Paris four years later.

    Tony Estanguet said the choices responded to a need to make the Olympics "more urban" and "more artistic". We have chosen to present the International Olympic Committee (IOC) with the four sports because they are creative, appealing to youth and completely in line with our vision. They reflect perfectly Paris 2024's identity.

    Breakdancing is an example of a sport "Which can be played anywhere and anytime in urban and other environment." It appeared at the 2018 Youth Olympics in Buenos Aires in the form of head-to-head "battles". In competitive breakdancing, "breakers" face off in "battles" against each other, either as individuals or teams. Breakdancers use a mix of physical and artistic skills combining elements from gymnastics or acrobatics (杂技).

    The IOC had announced that the number of competitors at Paris 2024 would be restricted to 10, 500, which limited the opportunity to add sports. But the organizers said the inclusion of the four sports in Paris would not necessitate the construction of permanent facilities and would involve just 248 competitors, of which 32 would he in breakdancing. The surfing events are likely to be held in established surf centres such as Biarritz or Lacanau in southwest France.

    The inclusion still need to be rubberstamped by the IOC, which is expected to decide on which sports to add in Paris after next years' Tokyo Games.

    Devon Gallagher, a college graduate from Philadelphia, wants the world to know exactly where she's been while she's on her worldwide vacation in a special way. The traveler, who was born with a bone disease, had her right leg amputated (截肢) at the age of four. Although the amputation caused inconvenience for Gallagher early on, she now sees it as nothing short of inspiration for living her best life.

    To spread that message. Gallagher has gone to social media, where she shares photos of her travels across the world, but instead of simply using a geo-tag (地理位置标签), she writes her location on her artificial leg before taking a picture.

    Now she has been taking pictures across the Continent, which show her cycling over the canal in Amsterdam relaxing on a wall overlooking the city of Barcelona, posing with a waffle in Brussels, taking in the beautiful Parthenon temple in Athens and enjoying a river ride in Budapest, all with the well-known locations written on her artificial leg.

    "I get a new leg every two years and I can choose the design on it. One day I had a sudden thought to get a chalk-board," Gallagher said. "My mum and grandmother didn't like the idea, but my friends thought it was great and told me to go for it, so I did."

    Gallagher said people often stare when she's writing on her leg, but once she shares the photos, she receives only positive feedback (反馈), "My leg hasn't stopped me from doing anything I've wanted to do," she said. "I don't know if it's my determination to prove to myself that I can do it, anyway, I've been able to keep up with people at my age and lead a pretty great life."

    Gallagher shows us that you should never let anything stand in the way of your dreams. And if life gives you an artificial leg, make art.
