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.

    The elementary means of communicating with other people is conveying messages by voice. This fact is widely acknowledged and we recognize the voice as a(n) {#blank#}1{#/blank#} characterizing the identity of a person. The array of voices is immeasurable as no two are exactly similar. They can be nasal, resonant or shrill produced in accordance with the individual physical {#blank#}2{#/blank#} of the throat.

    One possible implementation of the {#blank#}3{#/blank#} of voice recognition is voice profiling used by police analysts as a method of substantiating court evidence in trials. Every year, thousands of audiotapes with recorded interviews or {#blank#}4{#/blank#} utterances are put to the purpose to help identify the probable {#blank#}5{#/blank#}. Specialists dealing with the voice investigation claim that people can give themselves away by their {#blank#}6{#/blank#}, inflections or other voice attributes like pitch, intensity and loudness. A recorded sample is usually {#blank#}7{#/blank#} into electric impulses and later transformed into a pictorial recoding which is processed by a computer program. Very frequently voice analyst have a stake at deciphering the relevant information which may be {#blank#}8{#/blank#} with background noise or other interfering sounds until they attain the {#blank#}9{#/blank#} results.

    Thankfully, these efforts help the police detect individuals who threaten their victims by phone or inform about bomb {#blank#}10{#/blank#} or those who make offensive calls disturbing the peach of decent citizens.
