One concern relates to a lack of control over {#blank#}8{#/blank#} appears on the Internet. With television and radio there are editors to check the accuracy or appropriateness of the content of programs, and with television there are restrictions on what kinds of programs can {#blank#}9{#/blank#}(broadcast) and at what times of the day. With the Internet, parents can not check a published guide to determine what is suitable {#blank#}10{#/blank#} their children to see.

    Nowadays, it is common that more and more high school students open their own micro blogs on the Internet. For one thing, it can provide a colorful platform to show their talent. For{#blank#}1{#/blank#},it is a useful way to release their{#blank#}2{#/blank#}(press). And all these make it more and more popular with high school students.{#blank#}3{#/blank#}many parents and teachers hold a different view. They think that managing one's micro blog will take a lot of time and energy，{#blank#}4{#/blank#}should be used to study.

    In my view, I am greatly in favor{#blank#}5{#/blank#}this activity. Today the Internet is playing{#blank#}6{#/blank#}important and essential role in our life .Therefore, as high school students of the Information Age, we need to learn to make use of this{#blank#}7{#/blank#}(mean) tool to communicate and display ourselves. What's more, opening and organizing micro blogs need various abilities such as writing, designing, being skillful at computer and so on. Only if we master those abilities can we make a successful micro blog. As a result, we improve ourselves while{#blank#}8{#/blank#}(organize) our micro blogs .

    In fact, micro blog{#blank#}9{#/blank#}(oneself) is of little harm. It is your attitude towards it{#blank#}10{#/blank#}matters. We should take the advantages and avoid some bad effects.

    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 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 {#blank#}5{#/blank#}taking 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 and smiled, as we all did, {#blank#}8{#/blank#}(see) the color returning to her cheeks. Then {#blank#}9{#/blank#}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.

    My classmates and I had a really unforgettable experience，which made us very happy. We paid a visit {#blank#}1{#/blank#} Lucy's house yesterday. We didn't have difficulty finding her house because she {#blank#}2{#/blank#} (give) us clear directions. When we arrived at her house, her mother was preparing food for us. Then we began to help with the cooking. About an hour later, the food was ready, and we sat at the table enjoying the delicious food including fish and {#blank#}3{#/blank#} (vegetable). Finally we went to Ann's room where we watched our favourite TV programme together. {#blank#}4{#/blank#} (decorate) with flowers and balloons, the room was warm and comfortable.

    Almost all the ice covering the Bering Sea has melted(融化), scientists have confirmed, {#blank#}1{#/blank#} (throw) communities living around {#blank#}2{#/blank#} (it) shores into disorder. The region's ice cover {#blank#}3{#/blank#} (normal) lasts for at least another month, and this year it has disappeared earlier than any other year except 2017.

    Living in {#blank#}4{#/blank#} northern Pacific Ocean between Alaska and Russia, the Bering Sea is experiencing the climate change and has drawn attention this year for record-breaking levels of winter melting. In February, rising Arctic temperatures {#blank#}5{#/blank#} (lead) to around half the region's disappearing in the space of two weeks.

    A report {#blank#}6{#/blank#} (send) by the International Arctic Research Centre at the University of Alaska Fairbanks has outlined the real-world effects of these surprising environmental {#blank#}7{#/blank#} (change) on the many communities {#blank#}8{#/blank#} live in the Bering Sea region.

    In their report, the International Arctic Research Centre scientists wrote that while not every year will be as bad as this one, ice {#blank#}9{#/blank#} (form) is likely to remain low if the Bering Sea's waters remain warm. They also warn that communities will need to "prepare for more winters {#blank#}10{#/blank#} low sea ice and stormy conditions".
