Many years ago, when I worked as a volunteer at Stanford Hospital, I got to know a little girl {#blank#}1{#/blank#} Liz who was suffering from a rare and serious disease. Her only chance of recovery appeared to be a blood transfusion（输血）{#blank#}2{#/blank#} 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 explained 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{#blank#}5{#/blank#} (take) a deep breath and saying, “Yes, I'll do it {#blank#}6{#/blank#} it can save Liz.”

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

    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.

    There were some strange things happening in Tangshan {#blank#}1{#/blank#} July 28, 1976. For three days , water in the wells rose and {#blank#}2{#/blank#} (fall). The wells had deep cracks and a smelly gas came out of them. Pigs, {#blank#}3{#/blank#} (chicken) and even mice became too nervous {#blank#}4{#/blank#} (live) as usual. At 3:42 am, everything began to shake. {#blank#}5{#/blank#} seemed that the world was at an end. One-third of the nation felt it. 

    A terribly huge crack cut across the city. {#blank#}6{#/blank#} (immediate) the city lay in ruins. Two-thirds of the people died or were injured. Then {#blank#}7{#/blank#} (late) that afternoon, another big quake {#blank#}8{#/blank#} was almost as strong as the first one shook Tangshan. People began to wonder how long the disaster would last, {#blank#}9{#/blank#} not all hope was lost. Soldiers came to help those survivors. Slowly, the city began to {#blank#}10{#/blank#}（breath) again.

    Unlike some other European languages, English is a little tricky when it comes to writing. How a word {#blank#}1{#/blank#} (pronounce) and how it is actually spelt can be very different things. Take two simple {#blank#}2{#/blank#} (verb) like "have" and "save". Shouldn't they be pronounced the same? Why do "sir", "her" and "fur" all rhyme, but "fork" and "work" don't?

    Imagine, then, a situation {#blank#}3{#/blank#} two words are spelt and pronounced exactly the same way, but have {#blank#}4{#/blank#} (complete) different meanings. Welcome to the world of homonyms (同形同音异义词). {#blank#}5{#/blank#} (take), for example, the word "fair"—it can be a kind of event or an adjective to describe the colour of your hair.

    So how do you know which {#blank#}6{#/blank#} (mean) someone is referring to? You don't, except by the context. Obviously, if someone asks you to "give {#blank#}7{#/blank#} (they) a hand", they don't want you to remove {#blank#}8{#/blank#} is at the end of your arm.

    Sometimes even the context doesn't help much—the result can be amusing. These sentences play with the double meaning of a noun:

    I used to be {#blank#}9{#/blank#} banker, but I lost interest.

    A small boy swallowed some coins and had to go to hospital. When his grandmother phoned {#blank#}10{#/blank#} (ask) how he was, the nurse said, " No change yet."

    Chinese Kung Fu is an important part of traditional Chinese culture. It is probably one of the {#blank#}1{#/blank#}(early) and longest lasting sports in the world, {#blank#}2{#/blank#} uses both strength and brain. Over its long history, Kung Fu {#blank#}3{#/blank#}(develop) as a unique combination of exercise, self-protection and art. {#blank#}4{#/blank#} dates back to ancient times when people used tools {#blank#}5{#/blank#} (fight) against wild animals and gradually got experience in self-protection.

    {#blank#}6{#/blank#}(normal), an athlete in sports like track and field and ball sports retires in his or her 30s. Besides, injuries at a young age can affect our ability to keep {#blank#}7{#/blank#} (do) exercise in later life. In Chinese Kung Fu, however, it is {#blank#}8{#/blank#} different story. It {#blank#}9{#/blank#}(say) that Kung Fu not only exercises your physical body but also trains your spirit and your mind. And we can continue later in life when our {#blank#}10{#/blank#}(body) weaken.

The college entrance examination is just around the corner. {#blank#}1{#/blank#} (assign) and tests will keep many of you up late at night, and you may plan to make up for your{#blank#}2{#/blank#} (lose) sleep during the weekends. But is it useful?

A study shows that the habit of sleeping in{#blank#}3{#/blank#} weekends doesn't fix the damage done by a lack of sleep during the week. Even {#blank#}4{#/blank#} (bad), it may damage your health.

In the study, {#blank#}5{#/blank#} was conducted over 10 days, 36 healthy young men and women with different sleep requirements {#blank#}6{#/blank#} (divide) into three groups. The researchers found that people who lacked sleep ate more snacks and gained {#blank#}7{#/blank#} (weigh) quickly. That could be partially due to the shifting of the{#blank#}8{#/blank#} (biology) clock and changes to certain body hormones especially hunger hormones.

And {#blank#}9{#/blank#} they tried to sleep for as long as they wanted to on weekend, it was still insufficient(不够的) to meet standard sleep time because they found it difficult to fall asleep. Moreover, they were more likely{#blank#}10{#/blank#}(show) increased sensitivity (敏感性) to insulin(胰岛素) in both their muscles and their livers.
