I was born on the 17th of November 1828, in the village of Nam Ping, which is about four miles southwest of the Portuguese Colony (殖民地) of Macao, and is located on Pedro Island lying west of Macao, from which it is separated by a channel of half a mile wide.

    As early as 1834, an English lady, Mrs. Gutzlaff, wife of a missionary to China, came to Macao. Supported by the Ladies' Association in London for the promotion of female education in India and the East, she immediately took up the work of starting a girls' school for Chinese girls, which was soon followed by the opening of a boys' school.

    Mrs. Gutzlaff's comprador(买办) happened to come from my village and was actually my father's friend and neighbor. It was through him that my parents heard about Mrs. Gutzlaff's school and it was doubtlessly through his influence and means that my father got me admitted into the school. It has always been a mystery to me why my parents should put me into a foreign school, instead of a traditional Confucian school, where my big brother was placed. Most certainly such a step would have been more suitable for Chinese public opinion, taste, and the wants of the country, than to allow me to attend an English school. Moreover, a Chinese belief is the only avenue in China that leads to political promotion, influence, power and wealth. I can only guess that as foreign communication with China was just beginning to grow, my parents hoped that it might be worthwhile to put one of their sons to learning English. In this way he might become an interpreter and have a more advantageous position to enter the business and diplomatic world. I am wondering if that influenced my parents to put me into Mrs. Gutzlaff's School. As to what other sequences it has eventually brought about in my later life, they were entirely left in the hands of God.

    As for old people, some of the applications are hard to use because they didn't grow up with them. They don't have simple models of how they should work, what to do when something doesn't work or where to go for help. We make it as easy as possible to be used for people who are not familiar with the technology.

    I think there is huge potential and we are designing it. The ability to connect to friends, who remember the same movies and news and music, is really important, especially as people get old. They end up in retirement homes and they aren't always close to their friends. Allowing the network to help them connect with friends and family is a really powerful thing.

    My mother is an enthusiastic user of the Internet，although it took me years to get her to use e-mail. She was born with normal hearing, but lost it when she was 3.She was totally deaf for many years, until age 53, when she got ear aids. They work really well. That is a big change for her. But before then, her friends couldn't call her on the phone, so they insisted she use e-mail to communicate with them.

    Young people don't even think of the Internet as technology. It's just there, and they use it. There's been a very interesting change in communications styles between old people and young people. There are some kids who are now in their teens and aren't willing to make phone calls. And they think of e-mail as old-fashioned and slow.

    The reason why teens don't make phone calls seems to be that they don't know what to say. When they call they often stop for a while. They don't know what to say，and there's this silence. On the other hand, texting is considered proper, and it's okay if you don't answer. You might have been distracted. It's not considered rude. But it is considered strange if you're in this kind of voice conversation and simply stop talking.

    According to a new US study, couples who expect their children to help care for them in old age should hope they have daughters because they are likely to be twice as attentive overall.

    The research by Angelina Grigoryeva, a sociologist at Princeton University, found that, while women provide as much care for their elderly parents as they can manage, men do as little as they can get away with and often leave it to female family members.

    Using data from the University of Michigan Health and Retirement Study, a study which has been tracking a cross-section of over-50s for the last decade, she calculated that women provide an average of 12.3 hours a month of care for elderly parents while men offer only 5.6 hours.

    “Whereas the amount of elderly parent care daughters provide is associated with limitations they face, such as employment or childcare, sons' caregiving is associated only with the presence or absence of other helpers, such as sisters or a parent's spouse(配偶),” she explained.

    “Sons reduce their relative caregiving efforts when they have a sister, while daughters increase theirs when they have a brother.”

    “This suggests that sons pass on parent caregiving responsibilities to their sisters.”

    In the UK, the 2011 census(人口普查) showed that there are now around 6.5 million people with caring responsibilities – a figure which has risen by a tenth in a decade.

    But many are doing so at the risk of their own health. The census showed that those who provide 50 hours or more of care a week while trying to hold down a full- time job are three times more likely to be struggling with ill health than their working counterparts(相对应的人) who are not careers.

    A T-shirt that constantly monitors the heart's activity and detects abnormalities could help protect people against stroke. The T-shirt, which can be washed up to 35 times before it needs replacing, has been developed to improve the detection of dangerous heart conditions like atrial fibrillation( 心房颤动), which causes an irregular heart rhythm and raises the risk of stroke.

    At least one million people in Britain are known to have this condition; however, it's estimated that at least another 500,000 have it but haven't yet been diagnosed because they have no obvious symptoms. Some will have symptoms such as chest pain, dizziness and fatigue; but a large number of people have no idea they're ill until they suffer a stroke.

    Detecting atrial fibrillation involves carrying out an ECG(心电图). Conventional ECGs are done in a hospital and involve highly trained teams of staff attaching up to 24 separate electrodes(电极) to different parts of the body to measure electrical signals. But most patients experience abnormal rhythms only intermittently(间歇地). This means the chance of picking them up during a short hospital check is slim.

    Doctors sometimes issue patients with a device called a Holter monitor to wear under their clothes to try to pick up cardiac( 心脏的) problems. This is an electronic box which clips onto your waistband and is connected to a series of electrodes worn on the upper part of your body. But the box itself is quite bulky, hard to hide beneath clothing and involves a dozen or more wires being attached to the patient's chest.

    The Cardioskin T-shirt, which is made from cotton, could be a much more convenient alternative and can be worn 24 hours a day — meaning it is more likely to pick up any abnormal rhythms in the patient's heart. It has 15 tiny electrodes woven into the material which are strategically placed around the chest area to track the electrical signals from the heart as they travel across the main part of your body.

    The electrodes are powered by a battery which can be removed easily when you need to wash the T- shirt and feed results to a microchip which then sends them out wirelessly to an app. This converts( 转换) the data into an easy-to-read chart showing if the heart rate is abnormal. The results are shared with the patient's doctor so they can check the patient's heart without having to call them into the hospital.

    Martin Cowie, a professor of cardiology at Imperial College London, said, “Cardioskin could be an important development for cardiologists.”

    After decades of playing catch-up with the U.S. and Russian space programs, China did something neither nation nor any other had done this December: land a spaceship on the dark side of the moon.

    Strictly speaking, of course, the moon has no dark side. But because of the way it orbits Earth, our natural satellite shows us only one side－the other is hidden from our view. No one even saw the far side until 1959, when the Soviet Luna 3 spaceship flew around for a look and sent back photos. No astronaut or spaceship went there until this December, when the China National Space Agency (CNSA) launched a 2,500-pound lander called Chang'e-4 to the southern end of the lunar far side.

    Chang'e-4 operated a small rover (探测车) to survey the geography there for the first time ever. By examining the geography of its landing area, Chang'e-4 could solve longstanding puzzles about the moon, including how it formed 4.5 billion years ago. Chang'e-4 also carried a very small lunar biosphere (生态圈) containing silkworm eggs and a tiny greenhouse designed to grow potatoes in order to study the growth of the seeds on the moon.

    Besides Chang'e-4, China plans to launch Chang'e-5 in 2019. Its mission will be to gather moon rocks using an orbiter, a lander or collector, an ascent stage (上升器) and a capsule that will separate from the orbiter and return the rocks to the earth. ―With these missions, the Chinese will have shown complete mastery of flight in the space between the earth and the moon, said Paul Spudis, an experienced lunar researcher based in Houston.

    CNSA has already outlined ideas for Chinese astronauts to follow the robots to the moon. Pei Zhaoyu, deputy director of CNSA's Lunar Exploration and Space Program Center, told that China plans a permanent robotic lunar station in about 10 years and suggested a human presence on the moon another decade or so after that. Spudis said China's ambitious Chang'e-4 and Chang'e-5 missions should send human's plans for lunar return into rapid development.

    In 2015, a man named Nigel Richards memorized 386, 000 words in the entire French Scrabble Dictionary in just nine weeks. However, he does not speak French. Richards' impressive feat is a useful example to show how artificial intelligence works—real AI. Both of Richard and AI take in massive amounts of data to achieve goals with unlimited memory and superman accuracy in a certain field.

    The potential applications for AI are extremely exciting. Because AI can outperform humans at routine tasks—provided the task is in one field with a lot of data—it is technically capable of replacing hundreds of millions of white and blue collar jobs in the next 15 years or so.

    But not every job will be replaced by AI. In fact  four types of jobs are not at risk at all. First, there are creative jobs. AI needs to be given a goal to optimize. It cannot invent, like scientists, novelists and artists can. Second, the complex, strategic jobs—executives, diplomats, economists — go well beyond the AI limitation of single-field and Big Data. Then there are the as-yet-unknown jobs that will be created by AI.

    Are you worried that these three types of jobs won't employ as many people as AI will replace? Not to worry, as the fourth type is much larger: jobs where emotions are needed, such as teachers, nannies and doctors. These jobs require compassion, trust and sympathy—which AI does not have. And even if AI tried to fake it, nobody would want a robot telling them they have cancer, or a robot to babysit their children.

    So there will still be jobs in the age of AI. The key then must be retraining the workforce so people can do them. This must be the responsibility not just of the government, which can provide funds, but also of corporations and those who benefit most.
