This passage mainly tells us the {#blank#}1{#/blank#}(valuable) of a person. A collage student in this passage {#blank#}2{#/blank#} (choose)the wrong major and became more and more frustrated. He thought he couldn't be successful and achieve {#blank#}3{#/blank#}dream. {#blank#}4{#/blank#}, he only liked to listen to Yang' s class and never  {#blank#}5{#/blank#}(absence). He put a note and showed his value to Yang. One day, Yang told him the {#blank#}6{#/blank#}(different) between different potatoes. So this student understood the life and became successful.

    From this passage, I think, in our lives, we shouldn't move back when we have trouble with our study or work. {#blank#}7{#/blank#} (contrary), we must try hard to make our lives better and be {#blank#}8{#/blank#}(value) one in these common people. If we do, like this, we will show our value by ourselves and be found by top people. So we may change our destiny and become {#blank#}9{#/blank#}(success)

    All in all, I hope every one can show their value lively and {#blank#}10{#/blank#}(life)a successful life. Please remember：Be a potato, but be the best!

    When your dream is to become a footballer, nothing should get in your way—even if you are disabled.

    Gabriel Muniz, an 11-year-old Brazilian kid, was born without {#blank#}1{#/blank#}. Although his family thought he would have trouble {#blank#}2{#/blank#} a normal life, he started walking before he was one year old. His mother would go after him, expecting him to keep falling, {#blank#}3{#/blank#} he never fell. He took a while to make the jump from walking to playing football. In fact, there' s nothing he loves more than playing football. In his school, Gabriel not only does {#blank#}4{#/blank#} than other players in his school team but also is the captain of his gym team.

    He knows that his disability means he will never be able to play for a {#blank#}5{#/blank#} football team. So Gabriel is hoping that football {#blank#}6{#/blank#} a Paralympics (残奥会) event one day. He proved to everyone there he could go neck and neck with any other boy {#blank#}7{#/blank#}. Watching him play is unbelievable. In the past few years he {#blank#}8{#/blank#} a number of football skills. He does everything he can to copy Messi who he admires most. Luckily, he {#blank#}9{#/blank#} to go to Spain to meet his idol Messi and showed his talent in the Barcelona Football Club last year.

    Besides his talent, several achievements of {#blank#}10{#/blank#} were also surprising. His coach said he is proving that the disability only lies inside our heads and he is challenging the social rules.

    No one knows exactly {#blank#}1{#/blank#}the earth began. According to a widely accepted theory, the earth began with a “Big Bang”,{#blank#}2{#/blank#}exploded loudly and produced water vapor and many gases，{#blank#}3{#/blank#} (make) the earth's atmosphere. As the earth cooled down, water appeared and stayed{#blank#}4{#/blank#} the surface. It was the presence of water{#blank#}5{#/blank#}allowed the earth to dissolve harmful gases and acids into the oceans and seas, which made {#blank#}6{#/blank#}possible for life to develop. First, the appearance of small plants encouraged the development of early shellfish and all sorts of fish. Next, green plants began to grow on land. {#blank#}7{#/blank#}were followed by land animals. So reptiles appeared for the first time. Later, dinosaurs developed.{#blank#}8{#/blank#}they suddenly disappeared. After that, mammals came into being. Finally, humans appeared and spread all over the earth. However, they are putting too much carbon dioxide into the atmosphere, making the earth too hot{#blank#}9{#/blank#}(live) on. So whether life will continue on the earth will depend on {#blank#}10{#/blank#}this problem can be solved.

    It is hard work rather than luck that brings people success．Those {#blank#}1{#/blank#}are considered to be successful must have been working hard {#blank#}2{#/blank#} （achieve） their goal and their success can also benefit others．

    Some people argue that one can not succeed {#blank#}3{#/blank#} he works very hard．There are many examples to show that success {#blank#}4{#/blank#}（come）from hard work．One example is {#blank#}5{#/blank#} Madam Curie had been working all day and all night before she made the great discovery of radium．

    Other people think that luck and opportunity are {#blank#}6{#/blank#} （importance） than hard work．They argue that even if one works hard, he can not succeed {#blank#}7{#/blank#} luck and opportunity．For example, {#blank#}8{#/blank#} film star, Zhang Ziyi, could never be famous if she was not given a chance to play a role in the film．

    I think that {#blank#}9{#/blank#} hard work and good luck are important．If one wants to be successful, he has to work hard on one hand and he has to seize the opportunity and luck on the {#blank#}10{#/blank#}．These two factors are important for one's success．

    The sun at the center of our Solar System is one of the big reasons for{#blank#}1{#/blank#}we're here today, but it can also be a big trouble from time to time. Coronal mass ejections(CMEs) (日冕物质喷发)can seriously damage human{#blank#}2{#/blank#}(communicate) systems.

    For years, researchers{#blank#}3{#/blank#}(attempt) to forecast and predict CMEs in {#blank#}4{#/blank#}hope that warnings could help prevent damage to electronics and the power grid (电网). As it turns{#blank#}5{#/blank#}that a CME is more like a sneeze. Professor Mathew Owens of the University of Reading explains, "The research team and I have found they are more like an{#blank#}6{#/blank#}(expand) dust cloud or sneeze."

    When the solar wind acts on the CME as it moves through space, it causes the shape and behavior of the energy explosion {#blank#}7{#/blank#}(become) unpredictable. "Therefore if we want to protect{#blank#}8{#/blank#} (we) from solar eruptions, we need to understand more about the solar wind, "Owens says.

    The research team suggests that solar wind readings should {#blank#}9{#/blank#} (include) in the forecasting and prediction of future CMEs. This study could help scientists more{#blank#}10{#/blank#}(accurate) assess the risk that the ejections bring to human technology and potentially help reduce the damage they cause.
