About two years ago, I worked hard and entered a locally key school, which my parents were proud of it. From then up, I got up early and got to the school on time. After school, I went back home in time to help my parents do some housework while enjoy some light music. However, one day my mother persuading me to live at school to learn to be independent to prepare the future life. As I was unhappy, I understood my parents and followed their advices. Before living at school, I found it helped me save time and learn what to get on with others.
Are you facing a situation that looks impossible to fix?
In 1969,the pollution was terrible along the Cuyahoga River Cleveland, Ohio. It1.(be) unimaginable that it could ever be cleaned up. The river was so polluted that it2.(actual) caught fire and burned. Now, years later, this river is one of3.most outstanding（杰出的）examples of environmental cleanup.
But the river wasn’t changed in a few days4.even a few months. It took years of work 5.(reduce) the industrial pollution and clean the water. Finally, that hard work paid off and now the water in the river is6.(clean) than ever.
Maybe you are facing an impossible situation. Maybe you leave a habit7.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 are8.(amaze) stories of instant transformation, for most of us the9.(change) are gradual and require a lot of effort and work, like cleaning up a polluted river. Just be 10.(patience).
