Are you facing a situation that looks impossible to fix (修理)？

    In 1969, the pollution was 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 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.

    {#blank#}4{#/blank#}the river wasn't changed in a few days or 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#}(amazed) 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).

    Marry of us wake up feeling{#blank#}1{#/blank#}(tire) in the morning. Many of us ignore the problem as the day goes on,{#blank#}2{#/blank#} (forget) that it might have a{#blank#}3{#/blank#}(danger) effect. Society even glorifies “burning the candle at both ends” as{#blank#}4{#/blank#}sign of our devotion to work and family.

    Believe it{#blank#}5{#/blank#}not, all this bad sleep has far-reaching consequences. We just do not give ourselves enough chances to sleep. A survey of over 74,000 people found 35 percent reported sleeping less than seven hours daily{#blank#}6{#/blank#}average. Furthermore, the amount of sleep{#blank#}7{#/blank#}(change) greatly over the past 15 years.

    This lack of sleep can lead of many serious{#blank#}8{#/blank#}(problem). One study found that{#blank#}9{#/blank#}(simple) limiting yourself to six hours of sleep a night for two weeks had similar effects to staying up all night the night before,{#blank#}10{#/blank#}could make you perform poorly on a timed attention task.

    Long before Barack Obama became president of the United States, he wrote a book{#blank#}1{#/blank#}(call) Dream from My Father: A Story of Race and Inheritance, which has since become{#blank#}2{#/blank#}bestseller. It is an{#blank#}3{#/blank#}(appeal) book that includes what he went through during{#blank#}4{#/blank#}(he) childhood. Obama has little contact with his father{#blank#}5{#/blank#}roots were in Kenya because he left home when Obama was very young. His mother got married{#blank#}6{#/blank#}a student from Indonesia shortly after the family moved to Jakarta. A few years later, Obama came back with his grandparents to Hawaii, where he{#blank#}7{#/blank#}(attend) a private high school.{#blank#}8{#/blank#} (study) at Columbia in New York City, he then entered Harvard Law School. This autobiography also touches{#blank#}9{#/blank#}(heavy) on Obama's exposure to racism. Readers will find his reflections of childhood {#blank#}10{#/blank#}(experience) which involved racial discrimination to be especially moving.

With the improvement of life standards, there are a {#blank#}1{#/blank#} (grow) number of people traveling each year, {#blank#}2{#/blank#} is a good way to enjoy life. Some people would like to take a package tour (跟团游), {#blank#}3{#/blank#} others would rather travel on their own. I prefer the latter, because I feel that it's much more convenient and cheaper than taking a package tour as I {#blank#}4{#/blank#} (do) before.

First of all, traveling on my own, I can arrange my time and route {#blank#}5{#/blank#} (free). For example, when I get to someplace I like, I choose to stay longer and don't have to think about others. Secondly, the schedule is relatively tight joining package tours, and tourists can only stay very short time in tourist attractions. {#blank#}6{#/blank#} is difficult to enjoy every landscape carefully. {#blank#}7{#/blank#} (three), in order to earn money, some travel agencies force tourists {#blank#}8{#/blank#} (buy) things. In the meantime, traveling on my own is much cheaper. Finally, the trip is designed to relax. However, many people say that package tours are not to make them feel really {#blank#}9{#/blank#} (relax), but even more tired.

On the whole, I feel like {#blank#}10{#/blank#} (travel) on my own, which is more convenient.
