Most of us have lost our wallet at some stage in our lives. But few would imagine having it returned after 66 years. Edward Parker dropped his wallet in 1950 into an inaccessible spot behind a bookshelf, while working as an electrician, repairing World War Two bomb damage in the palace. The wallet stayed there until this year when a builder, doing some restoration work, finally found it.

    The wallet is a time capsule. Its leather and webbing has long ago started to disintegrate. But it contains numerous pictures of family, invoices, receipts, old union cards, results of a chest X-ray (sent to him in 1948, the same year as the NHS was founded), a national service card dated 9 December 1944 and a medical insurance card. His business cards—E Parker, Electrical Contractor—seem almost original. Reflecting the typical methods of contact of the time, they have an address but no telephone number.

    A month ago I was speaking to a press officer Lambeth Palace and he mentioned that the wallet had just been handed in. We thought it might be nice to try and work out whose it was and give it back to the family. Edward Parker is a pretty common name, but his medical card contained two places of residence—Poets Road and Springdale Road in north London. From this, Islington Council were able to find details of a marriage between Edward Parker and Constance Butler in 1947.

    That information was enough to work out that he was still alive and in a care home in Essex, so I went to visit him. Now 89, Edward has dementia (痴呆), but he was clearly happy to get the wallet and in particular, the photographs back. He pointed out pictures of his mother and father, his brother, his cousins and his wife Constance, who was with him when I visited. He hadn't seen a picture of his father since he lost the wallet, Constance, 90, said.

    Some educators told us that more years of school could help students get higher scores on intelligence tests. That was a finding of a study of teenage males in some countries. Now, another research shows that physical activity may help students do better in their classes.

    The research comes as educators in some countries are reducing time for activities like physical education. They are using the time instead for academic（学术的）subjects like math and reading. The studies appeared between 2008 and 2014. They included more than 55, 000 children, aged 6 to 18.

    Amika Singh:“ According to the results of our study, we can conclude that being physically active is beneficial for academic performance. There are, first, Physiological explanations, like more blood flow, and so more oxygen to the brain. Being physically active means there are more hormones(荷尔蒙)produced like endorphins(内啡肽). And endorphins make your stress level lower and your mood improved, which means you also perform better.”

    Also, students taking part in organized sports learn rules and how to follow them. This could improve their classroom behavior and help them keep their mind on their work.

    The study leaves some questions unanswered, however. Ms. Stash says it is not possible to say whether the amount or kind of activity affected the level of academic improvement. This is because of differences among the studies.

    The researchers said they found only two high-quality studies. They needed more high-quality studies to confirm (证实) their findings. They also pointed out that “results for other parts of the world may be quite different.”

    Still，the general finding was that physically active kids are more likely to do better in school. Ms. Singh says schools should consider that finding before they cut physical education programs. Her paper on “Physical Activity and Performance at School” is published in the Archives of Pediatric and Adolescent Medicine.

    In my living room, there is a plaque (匾) that advises me to “Bloom (开花) where you are planted.” It reminds me of Dorothy. I got to know Dorothy in the early 1980s, when I was teaching Early Childhood Development through a program with Union College in Barbourville, Kentucky. The job responsibilities required occasional visits to the classroom of each teacher in the program. Dorothy stands out in my memory as one who “bloomed” in her remote area.

    Dorothy taught in a school In Harlan County, Kentucky, Appalachian Mountain area. To get to her school from the town of Harlan, I followed a road winding around the mountain. In the eight-mile journey, I crossed the same railroad track five times, giving the possibility of getting caught by the same train five times. Rather than feeling excited by this drive through the mountains, I found it depressing. The poverty level was shocking and the small shabby houses gave me the greatest feeling of hopelessness.

    From the moment of my arrival at the little school, all gloom (忧郁) disappeared. Upon arriving at Dorothy's classroom. I was greeted with smiling faces and treated like a queen. The children had been prepared to show me their latest projects. Dorothy told me with a big smile that they were serving poke greens salad and cornbread for “dinner” (lunch). In case you don't know, poke greens are a weed-type plant that grows wild, especially on poor ground.

    Dorothy never ran out of reports of exciting activities of her students. Her enthusiasm never cooled down. When it came time to sit for the testing and interviewing required to receive her Child Development Associate Certification, Dorothy was ready. She came to the assessment and passed in all areas. Afterward, she invited me to the one-and-only steak house in the area to celebrate her victory, as if she had received her Ph. D. degree. After the meal, she placed a little box containing an old pen in my hand. She said it was a family heirloom (传家宝), but to me it is a treasured symbol of appreciation and pride that cannot be matched with things.  (360 words)

    Program fools humans

    Have you ever been so bored that you started a conversation with a “chatbot (聊天机器人)”? You probably discovered quickly that it wasn't much fun, because the things it says hardly ever make any sense and chatting with it doesn't provide the same kind of back-and-forth as a human conversation.

    That might have made you wonder: will a computer ever be able to talk like a human?

    That day is certainly getting closer now. A computer program named “Eugene Goostman” has successfully passed the Turing test – by fooling people into thinking it was a 13-year-old boy, reported AFP on June 9.

    While you may have never heard of the Turing test, it means a lot in the world of artificial (人工的) intelligence.

    According to USA Today, the test was first invented in 1950 by Alan Turing, a British computer expert best known for his code-breaking work during World War II. In his test, a group of human judges take turns having keyboard conversations for five minutes with two subjects – a human and a piece of computer software. If up to 30 percent of the judges fail to tell the two apart, the program is considered to have passed the test.

“If a machine is indistinguishable (无法区分的) from a human, then it could be said to be ‘thinking',” wrote Turing in his paper Computing, Machinery & Intelligence back in 1950.

    No computer had ever passed the Turing test before. But this time, Eugene Goostman, developed by two Russian scientists to simulate (模拟) a 13-year-old boy, managed to convince 33 percent of judges that it was human.

    Machines are close to “reaching the milestone of communicating with us in a way that we are comfortable with”, Professor Kevin Warwick of the University of Reading, UK, told The Telegraph. “This brings closer the time in which robots start to play an active role in our daily lives.”

    Some people feel a bit disturbed by the news. They worry that computers will outsmart humans in the near future and take over the world. But Warwick said that it is unlikely that this will happen any time soon. After all, computers have only just learned to have a five-minute conversation, while we humans can do so much more than that.

    A headache is the feeling you get when your head hurts. Headaches can differ from very mild to incredibly powerful. They can last anywhere from 10 minutes to hours. Very bad headaches are called migraines. People who suffer from migraine headaches often need to take the day off from school or work and lie in bed all day.

    Why do people get headaches? There are many possible causes. People who drink too much caffeine (in coffee or soft drinks, for example) or alcohol can end up with headaches. This is because these kinds of drinks take water away from the body. If the brain doesn't have enough water, it gets smaller and pulls away from the head. This can be extremely painful. The best way to get rid of this kind of headache is just to drink lots of water.

    Tension headaches happen when the body's muscles are too tight. When people feel stress, it is common for the muscles near the head to become tense. Tension headaches might also be caused by not getting enough sleep. Some people suffer from tension headaches for only short times but for other people, these kinds of headaches are a chronic problem that happens again and again. A massage (按摩) might help to stop a tension headache. If that doesn't help, you might need to see a doctor.

    Headaches can also be caused by much bigger health problems. For example, a head or neck injury can cause them. Headaches can also be a warming sign of a heart attack.
