One evening, my mother {#blank#}1{#/blank#}(cook) in the kitchen when someone {#blank#}2{#/blank#}(call) her up. My mother {#blank#}3{#/blank#}(hurry)to answer the phone. They {#blank#}4{#/blank#}(talk) and {#blank#}5{#/blank#}(talk) and my mother {#blank#}6{#/blank#}(forget) the cooking. When my mother {#blank#}7{#/blank#}(return) to the kitchen，what {#blank#}8{#/blank#} (do)she {#blank#}9{#/blank#}(see)? The food in the pan {#blank#}10{#/blank#}(burn)(燃烧)！She {#blank#}11{#/blank#}(take) the cover and {#blank#}12{#/blank#}(cover) the pan at once. In a second the fire was put out，but the food was burnt.

    What a pity!
