Are you facing a situation that looks impossible to fix?

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

    When I called up my mother in the countryside on the phone, she told me snakes came to her home now and then, and {#blank#}1{#/blank#} they seemed to have made their home there. I got the chance to distinguish {#blank#}2{#/blank#} by inventing something {#blank#}3{#/blank#} (mercy) to catch the snakes.

    No products can help me catch snakes, so I set out {#blank#}4{#/blank#} (research) the habits of snakes to trap them. I decided on three approaches: firstly, removing their habitat; secondly, {#blank#}5{#/blank#}(attract) them into {#blank#}6{#/blank#} trap, and thirdly cooling them. I used the {#blank#}7{#/blank#} (freeze) bowl to make the snakes less active, {#blank#}8{#/blank#} then collected them. The next day I released them into the wild.

    I have filled {#blank#}9{#/blank#} the form and filed my patent {#blank#}10{#/blank#} (apply) with the Patent Office.

    Do you know that some of the most interesting urban gardens are in unexpected places? They may be on top of {#blank#}1{#/blank#} public building, in the middle of a commercial district, or in the terminal of one of the world1s {#blank#}2{#/blank#} (busy) airports. You may have wandered on a sidewalk next to a “secret garden”{#blank#}3{#/blank#} realizing it was just around the comer or on the other side of a wall.

    If you don t know these attractive {#blank#}4{#/blank#} (nature) spaces exist, you might never experience them. At the same time, the fact that these places escape notice {#blank#}5{#/blank#}(make) them worth seeking out.

    St. Dunstan-in-the-East is a historic church in London, which has a history of hundreds of years. It survived the Great Fire of London in the 17th century, but it {#blank#}6{#/blank#}(hit) by a German bomb during World War II. St. Dunstan was rebuilt in the 1960s. Later, the city turned the grounds into a public garden.

    St. Dunstan is on a quiet street, but it's only a short walk from major {#blank#}7{#/blank#} (tour)attractions like the Tower of London. This peaceful park reportedly gets {#blank#}8{#/blank#}(relative)crowded at noon on sunny days during {#blank#}9{#/blank#} time office workers from the nearby buildings come to eat lunch. At most other times, however, it's a quiet place {#blank#}10{#/blank#} (get) away.
