    You've just hiccupped (打嗝) for the tenth time since you finished dinner. Wonder{#blank#}1{#/blank#}these funny noises are coming from? The part {#blank#}2{#/blank#}(blame) is your diaphragm, the muscle at the bottom of your chest. All hiccups start here.

    The diaphragm almost always {#blank#}3{#/blank#}(work) perfectly--it pulls down when you breathe in to help pull air into the lungs {#blank#}4{#/blank#}it moves up when you breathe out to help push air out of the lungs. But sometimes the diaphragm becomes upset, and when {#blank#}5{#/blank#}happens, it pushes up in an irregular way, making your breath come out differently {#blank#}6{#/blank#}how it normally does. When this irregular breath hits your voice box, you're left with a big hiccup. Things {#blank#}7{#/blank#}bother the diaphragm include eating too quickly or too much, stomachaches or feeling nervous.

    If you want to know {#blank#}8{#/blank#}to get rid of hiccups, here are some “cures”.{#blank#}9{#/blank#} (breathe) into a paper bag is one method some people use. Others think taking a mouthful of water is the way to become hiccup-free. Sugar under your tongue might also drive away the hiccups. And maybe the most famous {#blank#}10{#/blank#}(treat), having someone scare you, also helps beat the hiccups.
