I discovered that inside the-wonderful box lived an amazing person whose name was Information Please. There was nothing she did not know.

    One day my mother went out. I accidentally hurt my finger when I was playing with a hammer. I walked around the house sucking my finger, finally seeing the telephone. Quickly I dragged a chair over and climbed up.

    “Information Please, ”I spoke into the receiver. A click or two and a small clear voice spoke into my ear. “Information.”

    “I hurt my finger…”I cried into the phone.

    “Isn't your mother home?” came the question.

    “Nobody's home but me.” I sobbed.

    “Are you bleeding?” the voice asked.

    “No,” I replied, “I hit my finger with the hammer and it hurts.”

    “Can you open your icebox?” she asked. I said I could.

    “Then take a little piece of ice and hold it to your finger.” said the voice.

    After that, I called “Information Please” for everything. I asked her for help with my geography and she told me where Philadelphia was. She helped me with my math. She told me her name was Sally.

    Then, there was the time my pet canary（金丝雀）died. I called “Information Please” and told Sally the sad story. “Why is it that birds sing so beautifully and bring joy to all families, only to end up as a pile of feathers?” She listened, then said quietly, “Paul, always remember that there are other worlds to sing in.” Somehow, I felt better.

    One day when I called “Information Please” again, a different voice answered “Information.”

    I asked for Sally. “Are you a friend?” she said.

    “Yes,” I answered.

    “I'm sorry to have to tell you this,” she said. “She died five days ago.” Before I could hang up she said, “Wait a minute. Did you say your name was Paul?”

    “Yes.”

    “Well, Sally left a message for you. The note said, ‘Tell him I still say there are other worlds to sing in. He'll know what I mean.'” I thanked her and hung up. I knew what Sally meant.

    If you live in a big city, there are many thing to drive you crazy on your daily route, and it's not just overcrowded subway trains.

    Vicky Zhao is a mainlander working in Hong Kong. For her, one thing she can't put up with is people standing on the wrong side of the escalator(自动扶梯) in subway stations. "Escalators help us move faster and save time. It isn't a place to rest," the 24-year-old says. "I often see tourists block the way with their suitcases or chatting on the escalators during rush hours. It annoys me to no end."

    Admitting she is not the patient type, Zhao says things are much better in Hong Kong than in cities on the mainland where "stand right, walk left" signs are often ignored.

    The logic behind the "stand right, walk left" escalator etiquette(礼仪) seems obvious. Even though you may want to catch your breath while you're transported up or down, you should still consider others and leave enough space for people in a hurry, so that they can run and catch the train.

    Many cities' escalators, including London's and Beijing's, use the "stand right, walk left" system to speed up the flow of people. (Australia is an exception and you should stand on the left side instead.) But some cities discourage people from moving on escalators out of safety reasons. In Hong Kong's subway stations there are regular announcements asking people to "stand still" on escalators. Even so, most people in this fast-paced city observe the "stand right, walk left" etiquette.

    But the people who stand on escalators defend themselves by telling the walkers not to be so impatient. The BBC quotes one stander as saying: "If the person is in such a rush, why not just take the stairs? Even when the escalator is packed and there's nowhere to move, I see these same people complaining about not being able to pass."

    Whatever the escalator etiquette is in the place you live or visit, do what most people are doing and always be mindful of others: leave enough space between each other, don't stay at the end of the escalator, and if someone is blocking your way, a simple "excuse me" is enough.

    Throughout much of human history, man has been the measure of many, if not all, things. Lengths were divided up into feet and smaller units from the human hand. Other measures were equally characteristic. Mediterranean traders for centuries used the weight of grains of wheat to define (定义) their units of mass. The Romans used libra, forerunner of the pound, by referring to the weight of a carob (角豆树) seed.

    The sizes of similarly named units could also differ. The king's foot, used in France for nearly 1, 000 years after its introduction by Charlemagne in around 790 AD, was, at 32.5cm, around a centimeter shorter than the Belgic foot, used in England until 1300.Greek, Egyptian and Babylonian versions of water in a fixed container varied from one another by a few kilos, Nor was there agreement on such things within countries. In France, where there was no unified (统一的) measurement system at the national level, the situation was particularly terrible. The lieue (former measure of distance), for example, varied from just over 3 km in the north to nearly 6 km in the south.

    Although John Wilkins, an Englishman, first put forward a decimal system (十进制) of measurement in 1668, it was the French who in 1799 made it law. The Système International d'Unités (SI, or the metric system, as it is better known) developed from it and became the official measurement in all countries except Myanmar, Liberia and the United States. Now the International Bureau of Weights and Measures in Paris is set to give the metric system its biggest shake-up yet.

    At a meeting in Versailles, France, on November 16th, 2018, the world's measurement bodies are almost certain to approve a decision that will mean four out of the seven base SI units, including the kilogram, will follow the other three, including the metre, in being redefined in terms of the values of physical constants (物理常数).Each of the chosen constants has been measured incredibly precisely, which would mean that from May 20^th 2019 the constants will themselves be fixed at their current values for ever. Any laboratory in the world will then be able to measure, for example, the mass of an object as precisely as the accuracy of their equipment will allow.

    If you use social media to chase away loneliness, a new study suggests you're going against the grain.

    We may have heard a lot about the benefits of interacting with others online, but the findings of a study conducted by University of Pittsburgh School of Medicine scientists show a direct relationship between social media usage and feelings of isolation (隔绝). In short, the more time you spend on social media, the lonelier you may feel.

    With increased interaction on a large number of apps that allow for endless virtual connectivity, loneliness seems like the last problem frequent social media users would face, but according to the leader of the study Brain Primack, it has the exact opposite effect.

    "Mental health problems and social isolation are at widespread levels among young adults nowadays," Primack said, "We are naturally social creature, but modem life tends to separate us instead of bringing us together. While it may seem that social media presents opportunities to fill the social void (空隙), I think this study suggests that it may not be the solution people were hoping for."

    Primack and his team examined the social media habits of 1,787 U.S. adults aged 19 to 32 via a questionnaire that asked about the time and frequency they spent on the most popular social media platforms. Eventually, they determined that young adults who are constantly logging into social media reported more feelings of isolation than those with less social media usage. Frequent exposure to unrealistic descriptions on social media instead of face-to-face social interactions may give people the impression that others are living happier, more connected lives, and this may users feel more socially isolated in comparison.

    A famous Anglican Church stands in a quiet corner of Dunedin in New Zealand's South Island. Built in 1865, it is the city's oldest church still in use. Countless couples have gathered here to marry. It's where morning tears are shared, friendships formed and comfort given during times of loss.

    As with many churches, its walls are graced with a collection of beautiful stained-glass windows. Known as the "John Allen window", one window portrays the short life of a local man, John Allen, who died in 1915 in the Gallipoli campaign in Turkey.

    John was the son of Sir James Allen, who as Minister of Defense, helped plan and administer New Zealand's World War I strategy, which saw 100,000 troops sent to fight. With the war over and his son dead, Sir James chose to install a window in the church, with which the Allen family had strong ties.

    Divided into two parts, one depicts (描绘) St. George, the patron saint (守护神) of soldiers, while the other has an angel of peace, along with the words at the bottom, "John Hugh All Gallipoli, 6th June, 1915". Two trees with local birds on the branches can be seen and a kiwi walks at the bottom- reminders that John was a lover of birds.

    "There are many war memorials in the church," says the church. "However the 'John Allen window' stands out; it touches people because of the beautiful design, the New Zealand birds and because John's story, of a life so full of promise ending tragically in the war, reflects the lives and stories of so many others involved in World War I."
