Why men wolf down their meals {#blank#}1{#/blank#} women take their time? Many a woman has watched in disbelief as their partners eat their food minutes after sitting down to dinner. Now Korean researchers have discovered why: men and women {#blank#}2{#/blank#} (actual) chew differently. Women chew each individual mouthful more times — taking longer to finish {#blank#}3{#/blank#} (eat) their meal.

    The researchers hired 24 males and 24 females in South Korea. They recorded the size of people's bites, total chewing time per mouthful of food, total number of chews and how long {#blank#}4{#/blank#}   took the person to eat the entire meal. Men typically take {#blank#}5{#/blank#}   (large) bites with more “chewing power”, {#blank#}6{#/blank#} means they consume their meal more quickly than women.

    Though women were watched {#blank#}7{#/blank#} (have) the same chewing pace as men, they chewed each mouthful more times, slowing down the total time it took them to eat their meal.

    The study {#blank#}8{#/blank#} (publish) in the January issue of the Physiology and Behaviour Journal. But it flies in the face of an earlier result studied {#blank#}9{#/blank#} researchers at Nippon Dental University in Tokyo, Japan, which found no {#blank#}10{#/blank#} (different) in how the sexes chewed gum.

    On a{#blank#}1{#/blank#}(freeze) cold day,Mrs Smith's dog was hungry,but there was not any meat{#blank#}2{#/blank#}(leave) in the house.

    {#blank#}3{#/blank#} (consider) there was no better way,Mrs Smith took a piece of paper,and wrote the{#blank#}4{#/blank#}(follow) words: “Give my dog half a pound of meat.”Then she asked her dog to take it to the butcher's.When the butcher recognized that it was really the lady's handwriting,he did as he{#blank#}5{#/blank#}(ask) to.The dog was very happy,and ate the meat up immediately.

    The next day,the dog came again exactly at midday.And as{#blank#}6{#/blank#}(usually),it brought a piece of paper in the mouth.This time the butcher did not take a look at the paper,and just gave the dog its meat,for he had regarded the dog{#blank#}7{#/blank#}one of his customers.

    One day later,to the butcher's more surprise,it came at six o'clock and brought{#blank#}8{#/blank#}third piece of paper.Though {#blank#}9{#/blank#}(surprise),the butcher gave him{#blank#}10{#/blank#}he wanted.But what he didn't know was,that there were not any words on the paper!

    Many years ago, when I worked as a volunteer at Stanford Hospital, I got to know a little girl {#blank#}1{#/blank#}(name) Liz who was suffering from a rare and serious disease. Her only chance of{#blank#}2{#/blank#}(recover) appeared to be a blood transfusion（输血）from her 5-year-old brother{#blank#}3{#/blank#} had miraculously survived the same disease and had developed the antibodies needed to fight the {#blank#}4{#/blank#}(ill).

    The doctor{#blank#}5{#/blank#}(explain) the situation to her little brother, and asked the boy if he would be willing to give his blood to his sister. I saw him hesitate for a moment before taking a deep breath and saying, “Yes, I'll do it {#blank#}6{#/blank#} it can save Liz.”

    As the transfusion progressed, he lay in bed next to his sister{#blank#}7{#/blank#}smiled, as we all did{#blank#}8{#/blank#}(see) the color returning to her cheeks. Then{#blank#}9{#/blank#}(he) face grew pale and his smile faded. He looked up at the doctor and asked with a trembling voice, “Will I start to die right away?”

    Being young, the boy had{#blank#}10{#/blank#}(understand) the doctor; he thought he was going to have to give his sister all of his blood.
