George Bernard Shaw was interested in the way people spoke. He argued that he was never{#blank#}1{#/blank#} (mistake) about a person's status. However, Professor Higgins thought a superior social position was more dependent on grammar and pronunciation. Actually, his view was only accepted by a {#blank#}2{#/blank#} (hand) of his followers. Eliza, a flower girl, was ambitious to improve herself. {#blank#}3{#/blank#} (force)to earn money herself because her family was poor, she dreamed of working in a proper flower shop. George Bernard Shaw teamed {#blank#}4{#/blank#} with Professor Higgins to help her. An English teacher {#blank#}5{#/blank#}  (hire) to give her lessons. But after her first lesson, she was {#blank#}6{#/blank#} (apparent) disappointed because the teacher was so impatient with her. Actually, Eliza didn't give it up easily. {#blank#}7{#/blank#} (look) ahead, she decided to work hard. Knowing it was impossible {#blank#}8{#/blank#} (accept) in that profession if she did not speak correct English, she asked Professor Higgins to give her lessons. Trained for several months, she set out to speak in {#blank#}9{#/blank#} more attractive accent. Shortly, she became known as “the London songbird” {#blank#}10{#/blank#} her spoken English became so pleasant.

    When was the last time that you dialed a phone number from memory? It probably depends on how long you've been using {#blank#}1{#/blank#} like a cellphone. While some generations can recall the days of memorizing phone numbers, it's possible that members of Generation Z have never had to remember a single {#blank#}2{#/blank#}. Why is this? Because smartphones offer quick and convenient ways for storing and {#blank#}3{#/blank#} information. There is no need to memorize anything. But this isn't without consequence. As digital devices develop, more and more users' heavy reliance on them may be having disabling effects." Digital dementia（失智）"is the term being used by medical professionals to identify some of these effects.

    Some professionals like Jim Kwik, an expert in memory improvement and optimal brain performance, are taking a closer look at this effect. Kwik describes digital dementia like this:"...we're {#blank#}4{#/blank#} our brains to our smart devices. We're so reliant on our smartphones that our smartphones are making us stupid. As medical studies chart the decline in memory and cognitive skills among smartphone users, a connection is made between symptoms {#blank#}5{#/blank#} with dementia."

    The seriousness of overuse becomes {#blank#}6{#/blank#} when you consider just how young smartphone users are becoming. Author and speaker Simon Sinek points out that young minds" Are not ready for it! Their minds cannot cope with the dopamine（多巴胺）."Consequently, the overstimulation of screens and sounds lead to {#blank#}7{#/blank#} more often than not. So now parents, teachers and managers are asking how to handle the influx（汇集）of young people with this kind of addiction.

    First, monitor your cellphone use. Keep downloading applications like Forest or Checky. Then cut back on any {#blank#}8{#/blank#} usage. Set a specific goal of how much you think you should use your phone.

    Determine {#blank#}9{#/blank#} areas for cellphone use. For example, while you're at home, only allow yourself to check your phone somewhere like a home office. This way, the time in between tasks isn't {#blank#}10{#/blank#} filled with staring at your screen.

    For several decades, various types of artificial intelligence kept shocking the world. Robots could {#blank#}1{#/blank#} people in highly competitive games and then quickly destroyed their human competitors.

    AI long ago mastered chess, the Chinese board game Go and even the Rubik's cube, which it managed to solve in just 0. 38 second.

    Now machines have a new game that will allow them to {#blank#}2{#/blank#} humans: Jenga, the popular game in which players {#blank#}3{#/blank#} remove pieces from an increasingly unstable tower of 54 blocks, placing each one on top until the entire structure would {#blank#}4{#/blank#}.

    A newly released video from MIT shows a robot developed by the school's engineers playing the game with surprising accuracy. The machine is equipped with a soft gripper (夹子), a force-sensing wrist and an external camera, allowing the robot to detect the tower's {#blank#}5{#/blank#} the way a human might do

    Unlike in purely recognitive tasks or games such as chess or Go, playing the game of Jenga also requires mastery of physical acts such as pushing, pulling, placing, and arranging pieces. It must {#blank#}6{#/blank#} interactive physical operation, where you have to touch the tower to learn how and when to move blocks.

    Imitating it is rather difficult, so the robot has to learn in the real world, by working with the real Jenga tower. Recently, a relevant research was published in the journal Science Robotics. Researchers say the robot demonstrates that machines can learn how to perform certain tasks through actual touching instead of relying heavily on visual {#blank#}7{#/blank#}. That physical {#blank#}8{#/blank#} is significant, researchers say, because it provides further proof that robots can be used to perform {#blank#}9{#/blank#} tasks, such as separating recyclable objects from landfill trash and assembling consumer products.

    In a cellphone assembly line, the felling of any component is coming from force and touch rather than vision. To become an accomplished Jenga player, the robot did not require as much repetitive practice as you might imagine. Hoping to avoid reconstructing a Jenga tower thousands of times, researchers developed a method that allowed the robot to be trained on about 300 games. Researchers say the robot has already begun facing off against humans, who remain {#blank#}10{#/blank#} players—for now.
