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.

    Chen Lei studied art history and the early {#blank#}1{#/blank#} of China in a university. He was able to recognize the {#blank#}2{#/blank#} of different cultural relics from former times, especially the Tang and Song dynasties. One day he was looking in a second-hand furniture shop when he saw an {#blank#}3{#/blank#} object among the many different vases and {#blank#}4{#/blank#}. It was a mirror {#blank#}5{#/blank#} in the Song Dynasty and {#blank#}6{#/blank#} in the {#blank#}7{#/blank#} style of that time. He recognized that it was a {#blank#}8{#/blank#} cultural relic, but at a price he could afford, so he bought it at once. Later he gave it to his local museum. The people there were very happy and without {#blank#}9{#/blank#} consider it one of the treasures of their collection. To them, it was {#blank#}10{#/blank#} much more than Chen Lei paid.

    There is a difference between science and technology. Science is a method of answering theoretical questions; technology is a method of solving {#blank#}1{#/blank#} problems. Science has to do with discovering the facts and relationships {#blank#}2{#/blank#} in the observable natural world and with building up theories that serve to organize these facts and relationships; technology has to do with tools, techniques, and methods for carrying out the {#blank#}3{#/blank#} of science.

    Another difference between science and technology has to do with the {#blank#}4{#/blank#} in each.

    Progress in science does not consider the human factor. Scientists make a study of the universe, try to explain the rules of nature and strive to find out the truth. They can {#blank#}5{#/blank#} pay attention to their own or other people's likes or dislikes or to popular ideas about the fitness of things. What scientists discover may shock or anger people—as did Darwin's theory of evolution. But even a(n) {#blank#}6{#/blank#} truth is more than likely to be useful; besides, we have the choice of refusing to believe it! But hardly so with technology; we do not have the choice of refusing to hear the noises produced by an airplane flying overhead; we do not have the choice of refusing to breathe {#blank#}7{#/blank#}air; and we do not have the choice of living in a non-atomic age. Unlike science, progress in technology must be {#blank#}8{#/blank#} in terms of the human factor. Technology must be our slave and not the {#blank#}9{#/blank#}. The purpose of technology is to serve people in general, not merely some people; and future generation, not merely those who presently wish to gain advantage for themselves. Technology must be {#blank#}10{#/blank#} if it is to lead to a better world.
