Are you facing a situation that looks impossible to fix?

    In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It{#blank#}1{#/blank#}(be) unimaginable that it could ever be cleaned up. The river was so polluted that it{#blank#}2{#/blank#}(actual) caught fire and burned. Now, years later, this river is one of{#blank#}3{#/blank#}most outstanding（杰出的）examples of environmental cleanup.

    But the river wasn't changed in a few days{#blank#}4{#/blank#}even a few months. It took years of work {#blank#}5{#/blank#}(reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is{#blank#}6{#/blank#}(clean) than ever.

    Maybe you are facing an impossible situation. Maybe you leave a habit{#blank#}7{#/blank#}is driving your family crazy. Possibly you drink too much or don't know how to control your credit card use. When you face such an impossible situation, don't you want a quick fix and something to change immediately?

    While there are{#blank#}8{#/blank#}(amaze) stories of instant transformation, for most of us the{#blank#}9{#/blank#}(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be {#blank#}10{#/blank#}(patience).

    Bill Gates has said China is the best place for{#blank#}1{#/blank#}young to fulfill their ambitions to make the world a better place. In a lecture to Peking University students, he described the skepticism(怀疑论) in some developed countries about{#blank#}2{#/blank#} globalization works for ordinary people. He said the results of the US presidential election and the Brexit (英国脱欧) vote showed how any country may turn inward when{#blank#}3{#/blank#}(face) with difficult issues like immigration, security and global development.

    In a world suddenly short of experienced leaders, Gates praised China for shouldering{#blank#}4{#/blank#}great) responsibility for significant global issues like climate change and inclusive development. Gates told hundreds of students {#blank#}5{#/blank#}(attend) the lecture of his high hopes for China's youth, for they enter the work force at the time of China's rise{#blank#}6{#/blank#} a center of global progress and innovation(创新).

    "The world's eyes are on China{#blank#}7{#/blank#} (specific) on all of you. What an incredible thing is the belief {#blank#}8{#/blank#}you can make the world a better place. Now it is the best moment that you{#blank#}9{#/blank#}(have)," he said. "No matter what, if your ambition is to improve the world, this is the best time and the best place {#blank#}10{#/blank#}(struggle) for it."

    This weekend I was delighted to show my parents around Seville, as they {#blank#}1{#/blank#}(come) for a short but sweet visit. Although the weather wasn't the best, we still made {#blank#}2{#/blank#} best of our time together.

    Being reunited with the people you love in a new place {#blank#}3{#/blank#}(bring)such excitement. Showing them around the new city makes you {#blank#}4{#/blank#}(extraordinary)happy. For example, as Seville is known for flamenco(弗拉门科舞), I took them to see a famous {#blank#}5{#/blank#}(perform)my friends recommended to me, which gave us such a wonderful visual feast. Furthermore, getting to show your visitors the places {#blank#}6{#/blank#}(appeal)to you is a pleasant feeling, because you are eager to let them know where you love to spend your time. You are letting them get involved {#blank#}7{#/blank#} your new life. Also you have the opportunity {#blank#}8{#/blank#}(show) your loved ones the new places that they may fall in love with.

    So, after a two-day trip, I feel pleased to have had the time to explore those {#blank#}9{#/blank#}(attraction) with my parents. I am already looking forward to their next visit {#blank#}10{#/blank#}I can show them more of what Seville offers and what I am still yet to discover.
