Filmgoers should be told how many calories there are in the popcorn, ice cream and soft drinks that they buy in cinemas, according to the Food Standard Agency.

    Smaller popcorn buckets and drink cups should also be made{#blank#}1{#/blank#} , the nutrition inspector said.

    Tim Smith, chief executive of the agency, told The Times that cinemas should help to deal with the country's overweight {#blank#}2{#/blank#}.

    "There is a misbelief that popcorn is calorie-free, but that is not the case. It is a {#blank#}3{#/blank#}to us," he said. "Portion sizes are also a big issue, and there seems to be increasingly big packs on sale."

    He spoke as a number of food chains such as Pret A Manger, Wimpey and The Real Greek{#blank#}4{#/blank#}to put calorie counts on all their menus.

    A trial scheme（试行方案） with 21 food companies took place last summer, and {#blank#}5{#/blank#}are that consumers altered their buying habits when they realised the number of calories in a product.

    A consultation(征询意见) on the trial ends next month but Mr Smith is already planning the second drive for American-style calorie counts and is {#blank#}6{#/blank#} to win support from cinemas and other entertainment places, from football grounds to concert halls.

    Government{#blank#}7{#/blank#}suggest that two thirds of adults and a third of children are overweight. If trends are not {#blank#}8{#/blank#}, this could rise to almost nine in ten adults and two thirds of children by 2050, putting them at {#blank#}9{#/blank#} risk of heart disease, cancer and other diseases.

    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.

It is one of the great unsolved {#blank#}1{#/blank#}of this century.
