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)

    Climate change has caused a rise in sea levels. This has increased the amount of salt in fresh water {#blank#}1{#/blank#}(use) on coastal farms. As a result, farmers are {#blank#}2{#/blank#}(gradual) unable to use fields close to the sea. However, Marc Van Rijsselberg, a farmer in the Netherlands is now using a {#blank#}3{#/blank#}(mix) of sea and fresh water {#blank#}4{#/blank#}(grow) healthy and tasty vegetables.

    He teamed up with scientists from the Free University and divided a farm {#blank#}5{#/blank#}eight negated areas. Separate pipes pumped fresh and sea water, and a computer program created water with eight levels of salinity (含盐度).

    The water levels and the levels of salinity was {#blank#}6{#/blank#}(control) by computerized measuring devices called “sensors”. Mr. Van Rijsselberg said he was able to harvest vegetables from most of the eight testing areas. He said the vegetables were smaller than {#blank#}7{#/blank#} grown in fresh water. But he said they also had more sugar and salt, so they tasted much {#blank#}8{#/blank#}(good).

    He found that potatoes grew better than the other vegetables in the combination of sea and fresh water. Mr.Van Rijsselberg said four kinds of these potatoes would be sent to Pakistan {#blank#}9{#/blank#}thousands of hectares of land {#blank#}10{#/blank#}(damage) by salinization last year.

If one wants to keep fit, he should  {#blank#}1{#/blank#} {#blank#}2{#/blank#} instead of taking certain pills, which actually has a bad {#blank#}3{#/blank#}  {#blank#}4{#/blank#} people's health.
