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.

    ① Captain Ben Fawcett has bought {#blank#}1{#/blank#} unusual taxi and has begun a new service. The 'taxi' is a small Swiss aeroplane called a 'Pilatus Porter'. This wonderful plane can {#blank#}2{#/blank#} seven passengers. The most {#blank#}3{#/blank#} thing about it, {#blank#}4{#/blank#}, is that it can land anywhere.... Once he landed on the roof of a block of flats and {#blank#}5{#/blank#} another occasion, he landed in a {#blank#}6{#/blank#} car park.

    ② The Wayle is a small river that cuts across the park near my home. I like sitting by the Wayle on fine {#blank#}7{#/blank#}. ... I turned to look at the children, but there weren't any in{#blank#}8{#/blank#}: they had all run {#blank#}9{#/blank#}! The man laughed when he realized what {#blank#}10{#/blank#}. He called out to the children and threw the ball back to the bank.

    Sudan is the only male northern white rhino (犀牛) left in the world. That {#blank#}1{#/blank#} (mean) Sudan, 42, is the last hope for avoiding extinction. {#blank#}2{#/blank#}(protect) him, officials have placed him under 24-hour armed guard at the OI Pejeta Conservancy in central Kenya. Sudan lives there {#blank#}3{#/blank#} two female northern white rhinos, Fatu and Najin.

    Northern white rhinos, {#blank#}4{#/blank#} can weigh up to 5,000 pounds, were once plentiful across northern and central Africa. {#blank#}5{#/blank#} (hunter) have killed thousands of rhinos because of {#blank#}6{#/blank#} high demand for the animals，horns (角). Rhino horns, believed to have medical effects, are used in {#blank#}7{#/blank#} (tradition) Asian medicines. More than 1,000 rhinos {#blank#}8{#/blank#} (kill) in 2014 in South Africa alone and fifty-four rhinos in Kenya, which has a much {#blank#}9{#/blank#} (small) population.

    Sudan, Fatu, and Najin have had their horns {#blank#}10{#/blank#} (remove) so that they will not be hunted. People hope Sudan and one of the females will be able to have a baby. Sudan is very old, but scientists will not give up hope.

    Up to now, people in Amsterdam{#blank#}4{#/blank#}(enjoy)the convenience of cycling for decades. The city has special facilities for cyclists, {#blank#}5{#/blank#}can be used for free. Compared with other transportation in the city, bikes are{#blank#}6{#/blank#}(clean)and less expensive while also{#blank#}7{#/blank#}(offer)health benefits.
