Nobody is sure where and when the expression “apple-pie order” began. Some say that Scottish and English writers used the expression a long time ago. Others say it was first used in the northeastern American states known as New England. The housewives of New England cut their apples in even slices. Then they filled pie pans with them in an organized way, row upon row. As one writer said, the women of New England loved to have everything in its place. This perhaps explains why it generally is believed that the expression “apple-pie order” began in New England.

    Another old expression, “apple of discord”, comes from ancient mythology(神话), however. The myth says that all the gods and goddesses were sitting around the table to celebrate the marriage of Thetis and Peleus. One of the goddesses-Discord was a troublemaker. She threw away a golden apple on the table to be given as a prize to the most beautiful goddess.

    At one time, the tomato was called a love apple. That was a mistake. This is how the mistake happened: In the sixteenth century, Spain brought the tomato from South America after Spanish explorers had landed there. Spain then sold the tomato to Morocco. Italian traders carried it on to Italy. The Italian name for the tomato was “pomo di Moro” meant “d'amour” -the French word for love. And so “pomo di Moro” became the apple of love.

    People believe many things about the apple. One belief is that it has great powers of keeping people healthy. A very common expression is "an apple a day keeps the doctor away."

    Another belief is based on fact. The expression is "one rotten apple spoils the barrel." When an apple begins to go bad, it ruins all the other apples around it in the container. The expression has come to mean that one bad person in a group can cause everyone to act bad.

    A city without cars would be very strange, right? But Venice is such a city.

    Venice is in the northeast of Italy. It wasn't built on land, like Beijing or Shanghai, but on more than 110 islands. Seawater is everywhere around the city.

    Even so, travel isn't difficult. The waterways have always been the best way to get around. There are 117 waterways and more than 400 bridges that can guide you where you want to go.  People in Venice move from place to place by boat.

    Water makes the city special, but it is also a big problem. Sometimes tourists will have such strange experiences. One moment they walk across the Rialto Bridge, and there's nothing special. But when they come back to the bridge an hour later, it's underwater and everyone is wearing rain shoes.

    Once, people used too much underground water. This made the city get lower little by little. Now the city has gone down by 23 centimeters. Another problem is the rising seawater. The temperature has risen over the years. This has made the ice of the Arctic Ocean (北冰洋) melt (融化). Every year, high waters hit the city in autumn and winter. When a lot of water comes, more than half of the city is underwater.

    Scientists are trying different ways to stop the city from getting even lower. The Italian government has asked some of Italy's biggest companies to build the MOST project, which was planned to be build under the seawater to stop the rising water. Anyway, this project is helping solve the problem.

    This is the incredible school where the headteacher's unique dedication to handwriting practice means EVERY pupil is ambidextrous.

Only ten percent of the population are left-handed, and only ONE percent can write with both hands. But all 300 students at Veena Vandini School in India can write with both their left and right hand, with some able to do both at the same time—in different languages.

    Every 45-minute lesson features 15 minutes devoted to handwriting practice, to make sure all students at the remote rural school have the skill.

    The school, which was founded in 1999, is located in a remote area, in Singrauli district, Madhya Pradesh. School founder and former solider Vp Sharma said he was inspired to demand the lessons by India's first president.

     “I read in a magazine that Dr Rajendra Prasad used to write with both hands. This inspired me to give it a try. Later, when I launched my school at my native village, I tried training the students.

     “We began training students from standard I and by the time they reach standard III, they were comfortable writing with both the hands. Students of standard VII and VIII can write with speed and accuracy. Further, they can write two scripts simultaneously, one with each hand.

     “Students also know several languages, including Urdu.”

    Mr Sharma said their unique dedication to handwriting led South Korean researchers to visit and study the pupils two years ago, to find out more about ambidexterity.

    As self-driving cars come closer to being common on American roads, much of the rhetoric（说辞）promoting them has to do with safety. About 40,000 people die on U.S. roads every year, and driver errors are linked to more than 90 percent of crashes. But many of the biggest advocates of autonomous（自动的）vehicles aren't car companies looking to improve the safety of their existing products. Huge support for itself-driving technologies is coming from Silicon Valley giants like Google and Apple.

    Those of us who have studied the relationship between technology and society tend to look more carefully at the motivations behind any technologically push. In this case, it's clear that in addition to addressing safety concerns, Silicon Valley firms have a strong incentive（动机）to create a new venue for increasing the use of their digital devices. Every minute people spend on their mobile phones provides data—and often money—to tech companies.

    At present, digital devices and driving are in conflict: There are serious, often fatal, consequences when drivers use smartphones to talk or to text. Regulators and safety advocates look to resolve dial conflict by banning phone use while driving – as has happened in almost every state. But the tech companies are taking a different approach. The obvious answer for Silicon Valley is creating an automobile in which continuous cellphone use no longer poses a threat to anyone.

    In recent years, the amount of time adults spend on their mobile devices has grown rapidly. At the moment, it's around four hours a day for the average adult in the U.S. However, that rapid growth is likely to slow down as people run out of time that's available for them up to use their devices. Unless, of course, there's a new block of time that suddenly opens up. The average American now spends about 48 minutes in a car every day, a sizeable opportunity for increased cellphone use.

    Sop as the public conversation around autonomous cars highlights the safety advantages, don't forget the tech industry's powerful desire for more profits, which goes well beyond simply saving us from ourselves.

    You know the feeling-you have left your phone at home and feel anxious, as if you have lost your connection to the world. "Nomophobia" (无手机恐惧症) affects teenagers and adults alike. You can even do an online test to see if you have it. Last week, researchers from Hong Kong warned that nomophobia is infecting everyone. Their study found that people who use their phones to store, share and access personal memories suffer most. When users were asked to describe how they felt about their phones, words such as "hurt" (neck pain was often reported) and "alone" predicted higher levels of nomophobia.

    "The findings of our study suggest that users regard smartphones as their extended selves and get attached to the devices," said Dr. Kim Ki Joon. "People experience feelings of anxiety and unpleasantness when separated from their phones." Meanwhile, an American study shows that smartphone separation can lead to an increase in heart rate and blood pressure.

    So can being without your phone really give you separation anxiety? Professor Mark Griffiths, psychologist and director of the International Gaming Research Unit at Nottingham Trent University, says it is what is on the phone that counts-the social networking that creates Fomo (fear of missing out).

    "We are talking about an internet-connected device that allows people to deal with lots of aspects of their lives," says Griffiths. "You would have to surgically remove a phone from a teenager because their whole life is rooted in this device."

    Griffiths thinks attachment theory, where we develop emotional dependency on the phone because it holds details of our lives, is a small part of nomophobia. For "screenagers", it is Fomo that creates the most separation anxiety. If they can't see what's happening on Snapchat or Instagram, they become panic-stricken about not knowing what's going on socially. "But they adapt very quickly if you take them on holiday and there's no internet," says Griffiths.

    When you watch a movie these days, it's difficult to tell what's real and what's created by using computers. Visual effects can even change how movies are made.

    Almost anything that can be imagined by a director can now become reality in the world of movies. "We're really not limited by the technology, '' said David Smith, the CEO of Sony Pictures Imageworks. Mr Smith said that with today's technology, the digital world was more realistic than ever before. For The Amazing Spider-Man 2, Mr Smith's team created a Times Square that was exactly like the real one in New York. "If there are lights inside the stores that are lighting areas inside the store we put those lights there," said Mr Smith.

    But there was still one challenge for visual effects artists, said Paul Debevec of the University of Southern California Institute for Creative Technologies. "We're still trying to figure out how to perfect the human face in movies, " said Debevec. He said the movie — The Curious Case of Benjamin Button was still one of the best examples of computer generated movies, as actor Brad Pitt could be from an aged man to a baby in the movie.

    Mr Debevec added that besides changing the look of an actor's face, there could be another use for digital faces in the entertainment. Last year, effects artists created a digital face of the Asian pop singer Teresa Teng who was dead. Fans could still see and hear the concert on YouTube.

    Mr Debevec expects directors will start to use more virtual production techniques, like those seen in the movie Avatar. Mr Debevec says that with virtual production, there won't be a need for so many people behind the scenes. But visual effects artists agree, even with advanced technology, there is no replacement for a real actor showing a character in a movie.
