All scientists subscribe {#blank#}1{#/blank#} the view that it is human activities that have caused the global warming. Huge {#blank#}2{#/blank#} (quantity) of carbon dioxide produced by burning fuels like coal,  natural gas and oil {#blank#}3{#/blank#} (result) in the "greenhouse effect". All scientists also agree that the levels of carbon dioxide keep on {#blank#}4{#/blank#} (increase), so more heat energy tends to be {#blank#}5{#/blank#} (trap) in the atmosphere. {#blank#}6{#/blank#} the scientists have different attitudes towards this phenomenon. On the one hand, some think the {#blank#}7{#/blank#} of increasing the temperature by 5 degrees would be a catastrophe. On the other hand, others are {#blank#}8{#/blank#} to this view and believe that there will be few bad environmental {#blank#}9{#/blank#} caused by more carbon dioxide. On the contrary, they think it will be beneficial to plants, crops and a greater range of animals, {#blank#}10{#/blank#} will make people's life better.

    I believe doing good deeds can bring me happiness. I've been making breastpins (胸针) and gifting them to everyone possible and if you ask me why I do it, it's because {#blank#}1{#/blank#} the joy which just bursts forth from my inner heart. The smile that lights up at the sight of the breastpin is worth anything you'd wish for and it goes much {#blank#}2{#/blank#} (far). From that moment on, there's a {#blank#}3{#/blank#} (connect) between gifting breastpins and happiness.

    We exchange warm hugs, smiles and a million “thank you”. This hobby that has so at- traded me has opened my heart and brought me out of my cocoon (茧). Now, I don't mind {#blank#}4{#/blank#} (start) a conversation with a stranger, wishing him or her well and gifting a breastpin because I know that this little piece of art will do {#blank#}5{#/blank#} (it) magic of breaking all barriers. We unite and share many {#blank#}6{#/blank#} (story). And next time our paths cross, we greet {#blank#}7{#/blank#} smile, which is enough {#blank#}8{#/blank#} (brighten) the day.

    This morning, I received {#blank#}9{#/blank#} heart-warming post on Instagram (照片墙) from a friend who I {#blank#}10{#/blank#} (give) a blue and white spotted breastpin before. She shared it along with the shells collected from the beach. She loved sea shells and the colors blue and white. So, here's why I make breastpins.

    Are you facing a situation that {#blank#}1{#/blank#}(be) impossible to fix?

    In 1969, the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It was 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 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 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 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).
