— Of course. After all, it has paid off.

    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).

    It feels great when you make someone smile.

    My neighbors are a senior couple {#blank#}1{#/blank#}are always full of positive atmosphere. They have a little basil plant at their lobby（门廊）area, and it {#blank#}2{#/blank#}(water) by the husband, Mr Green,{#blank#}3{#/blank#} (regular). He prays and takes care of it like a small baby. The weather is extremely hot now, so he spends so much time with it.

    Then Mr Green and his wife had to travel and leave{#blank#}4{#/blank#}about three to four {#blank#}5{#/blank#}(week) and was so worried about the basil plant. We overheard him discussing this with {#blank#}6{#/blank#}(we) grandmother. When he {#blank#}7{#/blank#}we decided to take care of the basil plant just like he would.

    This morning when they returned we were eagerly waiting for them, especially Mr Green, to see his{#blank#}8{#/blank#}(react). He smiled at the gate {#blank#}9{#/blank#}told his wife, “See, every plant of ours is still fresh and green.” My grandmother responded that it might have been because of all your love for it. It was such a great feeling {#blank#}10{#/blank#}(hear) that interaction.

    Ski touring is exactly that—touring on skis. It combines {#blank#}1{#/blank#} best bits of skiing and mountaineering and provides the perfect way {#blank#}2{#/blank#} (explore) the mountain in winter. The {#blank#}3{#/blank#} (advantage) of ski touring are that you can really escape the crowds, enjoy the peace of the mountains and {#blank#}4{#/blank#} (reward) with breathtaking views and exciting descents.

    Ski touring involves both going up and down the mountain; both of {#blank#}5{#/blank#} (they) present challenges and new skills are to be acquired. There is much to learn about getting up the mountain that improves efficiency and saves energy. {#blank#}6{#/blank#} (similar) ，you want to be prepared to enjoy going down, which means learning to deal with the variety of snow conditions you will face. Because all ski touring is very demanding, you must be {#blank#}7{#/blank#} good physical condition. The fitter you are, the {#blank#}8{#/blank#} (much) fun you will have.

    Rapidly changing conditions and the human factors are the primary reasons for accidents. The human factors include stress, poor {#blank#}9{#/blank#} (communicate), over-confidence and tiredness. You should always ski within the limits of your ability, and make sure you know {#blank#}10{#/blank#} to navigate (导航) properly with map and compass.

    Friends play an important part in our {#blank#}1{#/blank#} (life). Though we may take friendship for granted, we often don't clearly understand {#blank#}2{#/blank#} we make friends. While we get on {#blank#}3{#/blank#}(good) with many people, we are usually friends with only a few—for example, per student usually {#blank#}4{#/blank#} (have) about 6 friends. In all the cases of friendly relationships, two people like one another and enjoy {#blank#}5{#/blank#} (be) together. {#blank#}6{#/blank#}fact, as we get to know people, we take into account things like age, race, economic condition, social position, and intelligence. Although these things are not of great {#blank#}7{#/blank#} (important), {#blank#}8{#/blank#} is more difficult to get on with people when there is an obvious difference in age and background. Compared with marriage, there are no friendship ceremonies to {#blank#}9{#/blank#} (strong) the connection between two people. But the mutual（彼此的）understanding that results from common experiences and emotions does seem to create a powerful bond, {#blank#}10{#/blank#} can overcome difference in background, and break down barriers（障碍）of age, class and race.

    Environment-friendly ideas have been created to supply people with helpful {#blank#}1{#/blank#}(tip) on how they can help the environment {#blank#}2{#/blank#} well as save money. I honestly believe that everyone wants to help the environment, even if they do or do not believe in global warming.

    With power bills, water bills and all other expenses{#blank#}3{#/blank#}(continue)to rise, it's very hard for the average worker. No matter what your {#blank#}4{#/blank#}(finance) position is , there is always something everyone can do {#blank#}5{#/blank#}(help) save our environment.

    We are not the only ones that live on this {#blank#}6{#/blank#}(amaze) planet. We also share it {#blank#}7{#/blank#}a wide range of strange and wonderful animals. It would be a great tragedy if they {#blank#}8{#/blank#} (be) not around for our future generations to enjoy. Every little bit helps, so please do all {#blank#}9{#/blank#} you can to protect our environment and the environment of these surprising animals.

    I hope these environment-friendly ideas can help everyone to do {#blank#}10{#/blank#}(they) bit for the environment and to make this world a better place.
