A group of classmates got together to visit their old teacher. These classmates all had good jobs and made lots of money. They talked {#blank#}1{#/blank#} (happy). The teacher asked them the difficulty they had{#blank#}2{#/blank#} (achieve) their dreams. Then their talk soon turned to complaining about the stress in work and life. The teacher went to {#blank#}3{#/blank#} kitchen and came back with a large pot of coffee and many cups-china ones, plastic ones and glass ones. Some are plain looking, some are expensive and some are lovely. The teacher told them to help {#blank#}4{#/blank#}(they)to the coffee.

    When all the students had a cup of coffee in hand, the teacher said, “Can you notice that all of you took nice-looking expensive cups, leaving {#blank#}5{#/blank#} the plain and cheap ones? You want only the best for yourselves,{#blank#}6{#/blank#}is the source of your problems.”

    “What all of you really wanted was coffee, not the cup,{#blank#}7{#/blank#} you went for the best cups and then began looking at each other's cups.”

    “Now think about this: life is the coffee, and the jobs, money and position in society {#blank#}8{#/blank#} (be) the cups. They are just {#blank#}9{#/blank#} (tool) to hold, and do not change the life. Sometimes, by caring only about the cups, we fail {#blank#}10{#/blank#}(enjoy) the coffee. So don't let the cups drive you, and enjoy the coffee instead.”

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

    But 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).

    Diets have changed in China — and so too has its top crop. Since 2011, the country {#blank#}1{#/blank#}(grow) more corn than rice. Corn production has jumped nearly 125 percent over {#blank#}2{#/blank#} past 25 years, while rice has increased only 7 percent.

    A taste for meat is {#blank#}3{#/blank#} (actual) behind the change: An important part of its corn is used to feed chickens, pigs, and cattle. Another reason for corn's rise: The government encourages farmers to grow corn instead of rice {#blank#}4{#/blank#} (improve) water quality. Corn uses less water {#blank#}5{#/blank#} rice and creates less fertilizer(化肥) runoff. This switch has decreased {#blank#}6{#/blank#} (pollute) in the country's major lakes and reservoirs and made drinking water safer for people.

    According to the World Bank, China accounts for about 30 percent of total {#blank#}7{#/blank#} (globe)fertilizer consumption. The Chinese Ministry of Agriculture finds that between 2005—when the government {#blank#}8{#/blank#} (start) a soil-testing program {#blank#}9{#/blank#} gives specific fertilizer recommendations to farmers - and 2011, fertilizer use dropped by 7.7 million tons. That prevented the emission(排放) of 51.8 million tons of carbon dioxide. China's approach to protecting its environment while {#blank#}10{#/blank#} (feed) its citizens "offers useful lessons for agriculture and food policymakers worldwide." says the bank's Juergen Voegele.
