When I was 12, all I wanted was a signet (图章) ring. They were the "in" thing and it seemed every girl except me had one. On my 13th birthday, my Mum gave me a signet ring with my initials(姓名首字母) carved into it. I was in heaven.

    What made it even more special was that it was about the only thing that wasn't being "replaced". We'd been burnt out in fires that swept through our area earlier that year and had lost everything—so most of the " new" stuff (东西) we got was really just to replace what we'd lost. But not my ring. My ring was new.

    Then, only one month later, I lost it. I took it off before bed and it was missing in the morning. I was sad and searched everywhere for it. But it seemed to have disappeared. Eventually, I gave up and stopped looking for it. And two years later, we sold the house and moved away.

    Years passed, and a couple of moves later, I was visiting my parents' when Mum told me that she had something for me. It wasn't my birthday, nor was it Easter or Christmas or any other gift-giving occasion. Mum noticed my questioning look. " You'll recognize this one," she said, smiling.

    Then she handed me a small ring box. I took it from her and opened it to find my beautiful signet ring inside. The family who had bought our house 13 years earlier had recently decided to do some redecorations, which included replacing the carpets. When they pulled the carpet up in my old bedroom, they found the ring. As it had my initials carved into it, they realized who owned the ring. They'd had it professionally cleaned up by a jeweler before sending it to my mother. And it still fits me.

    China's cancer researcher Zhu Chen, together with two French researchers Anne Dejean and Hugues de Thé, received Sjoberg Prize 2018 in Stockholm Concert Hall, Sweden on Friday.

    “We used wisdom from both Chinese and Western medicine and offered a cure to one of the most deadly cancers,” Chen told Xinhua, “I feel that Chinese medicine has potential to contribute more to human health. It struggles for benefiting all mankind. It's a language of peace, and of development and progress.” Chen recalled the cooperation with the two French researchers for over 30 years.

    This year's Sjoberg winners have developed a new and targeted treatment for a specific form of blood cancer called acute promyelocytic leukaemia (急性早幼粒白血病). It was once one of the deadliest forms of cancer, but it is now possible to cure nine out of ten patients who receive the new treatment. The winners have made this revolutionary development possible by methodically mapping the molecular mechanisms responsible for the disease.

    The Prize is awarded by the Royal Swedish Academy of Sciences and is funded (资助)by the Sjoberg Foundation. The foundation, with a donation of 2.5 billion US dollars, was founded in 2016, and serves to promote scientific research that focuses on cancer, health and the environment.

    The Prize is an annual international prize in cancer research awarded to individual researchers or research groups. The prize amounts to one million US dollars, of which 100,000US dollars is the prize sum and 900,000US dollars is funding for future research.

Ways to make a great first impression

    You've heard it a million times already, but it really does take but a few seconds to make that all-important first impression（印象）. Here are some easy ways for you to impress your classmates or teachers.

     {#blank#}1{#/blank#}

    Before you shake hands with somebody, make sure that your hands are clean. The handshake should not be too strong or weak. Most people use their right hands, unless they have a reason to use the left. {#blank#}2{#/blank#}

    Be on time

    When meeting someone for the first time, arriving on time is as important as breathing. You may have an excuse, but that will leave the person who hardly knows you with a bad impression.{#blank#}3{#/blank#} It's better to be hanging around the place than be stuck in traffic.

    Introduce yourself and ask for names

Make sure you properly introduce yourself. Ask for their names in a polite way. {#blank#}4{#/blank#} This will increase the chances of their remembering your name in the future. Always remember to stand up when greeting someone and be sure to introduce them to anyone you're with.

    Make good conversation

To get the most out of your discussion, try to find something common between the two of you.

    {#blank#}5{#/blank#} A person will feel more comfortable with someone they can relate to（产生共鸣）.

A. Use body language

B. Have a proper handshake

C. Repeat the name and use it later in conversation.

D. As a general rule, plan to arrive about 30 minutes early.

E. It could be a similar taste in clothes or a common hobby.

F. You'll be in serious trouble if you leave them with a bad impression.

G. However, don't have your left hand in your pocket because this appears impolite.                         

    Allan Guei, 18, was a star basketball player at Compton High School in the Los Angeles area before he graduated last month. His good grades made him eligible for an unusual competition: A free-throw contest in the Compton High gymnasium. The top prize: ＄40,000 in scholarship money.

    Guei, whose parents immigrated to the United States from the Ivory Coast, knew how much that financial aid could mean for his family. He was also feeling a fair share of pressure as students and teachers crushed into the gym to watch Guei and seven other randomly compete against each other.

    Guei won the free-throw contest by one basket and netted the ＄40,000. But it's what he did next that's truly astonishing.

In the weeks following the March free-throw competition, Guei learned that he'd scored a full-ride basketball scholarship to California State University—Northridge. NCAA(全国大学生体育协会)rules allowed Guei to accept the athletic scholarship and also keep most of the ＄40,000 he had won.

    But Guei couldn't stop thinking about the seven talented runners-up from the free-throw contest. They, too, had dreams and very real needs. So, he asked Principal Jesse Jones to make a surprise announcement at Compton High's graduation ceremony: Geui wanted to donate the ＄40,000 to the other seven students.

    “I've already been blessed so much and I know we're living with a bad economy, so I know this money can really help my classmates,” Guei said in a statement. “It was the right decision.”

    Guei elaborated on his decision to give the money away in an interview with ESPN(体育电视网): “I was already well taken care of to go to school, to go to university for free… I felt like they needed it more than I did.”

    The Internet has completely changed the workplace over the past three decades. Artificial Intelligence is now all set to do the same, and businesses that don't take advantage of the technology risk being left behind.

    Global tech giants (巨头) like Amazon have been leading the change, and businesses of all sizes are now using the technology for employing and managing their staff.

    Among them is L'Oreal. With about a million applicants for roughly 15,000 new positions each year, the company is using AI to hire.

    “We really wanted to save time and focus more on quality, diversity and candidate experience. And AI solutions were the best way to go faster on these challenges, said Eva Azoulay, global vice-president of L'Oreal's Human Resources Department.

    The company uses Mya, a chatbot, to save employers' time during the first stage of the process. It handles routine questions from candidates, and checks details such as availability and visa requirements. Should candidates make it to the next round, they'll run into Seedlink, an AI software that scores applicants based on their answers to open-ended interview questions. These scores don't replace human judgment, said Azoulay, but they do pick out candidates who might not seem like obvious choices.

    Early results have been promising. For one internship program, where 12,000 people apply for about 80 spots, employers claim they saved 200 hours of time while hiring the most diverse group to date.

    Other businesses have gone beyond employment and are using AI to help manage employees. Some UK firms have started using Isaak, a system designed by the London-based company StatusToday, to track how many hours staff spend online and the number of emails they receive. London real estate agent JBrown has been using this system since March. CEO James Brown said it helps the firm understand employees' habits and prevent them from overworking. "It enables us to solve bottleneck problems and relieve overburdened employees," he said.

    Despite these examples of good practice, there is still a long way for AI to reach its full potential (潜力), and the technology comes with risks. Another AI danger could be its impact on jobs through automation (自动化). McKinsey predicts AI could add $13 trillion to the global economy by 2030, with early adopters doubling their cash flow over that period. But the demand for repetitive (重复的) or digitally-unskilled jobs could drop by around 10%, the consulting firm said in a 2018 report.

    "What kind of rubbish are you?" This question might normally cause anger, but in Shanghai it has aroused complaints over the past week. On July 1st the city introduced strict rubbish-sorting regulations as a model for the country. Residents must divide their waste into four separate categories and throw it into specific public bins. They must do so at scheduled times, when monitors are present to ask the nature of one's rubbish, otherwise, they will face fines or worse.

    Shanghai authorities are responding to an obvious environmental problem. It generates 9 million tonnes of garbage a year, more than London's annual output and rises quickly. But like other cities in China, it lacks a recycling system. Individuals who fail to recycle could be fined up to 200 yuan (＄29). For repeat, the city can add black marks to their credit records, making it harder for them to obtain bank loans or even buy train tickets.

    Some object to this. Peng Feng of the Shanghai Academy of Social Sciences warns that the use of the credit system is overkill, raising a risk that officials will abuse their power. But others say a tough campaign is necessary. "Slowly people will get used to it," says Li Changjun of Fudan University.

    Many residents support recycling but are frustrated by the details. Rubbish must be divided according to whether it is food, recyclable, dry or harmful, the distinctions among which can be confusing, though there are apps to help work it out. Some have complained about the rules surrounding food waste. They must put it straight in the requisite public bin, forcing them to tear open plastic bags and toss (撕开) it by hand. Most upsetting are the short windows for throwing rubbish, typically a couple of hours, morning and evening. Along with the monitors at the bins, this means that people go at around the same time and can keep an eye on what is being thrown out; no one wants to look bad.
