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).

    My name is Billy Smith. I'm 50 years old this year. I tipped the scales at 32 stone two years ago. {#blank#}1{#/blank#}(lucky), I managed to lose weight.

    I began to gain weight when my mom developed Parkinson's disease in 1992. I soon became her caregiver, and continued to provide her {#blank#}2{#/blank#} care for over 10 years. But when the pressure of taking care of my mother and {#blank#}3{#/blank#}(keep) my job got too much for me, I began to skip meals and feed on fast food. I gained weight quickly.

    My huge weight gain caused me to develop high blood pressure. I also had {#blank#}4{#/blank#}(difficult) in breathing at times. In 2014 I went to see my doctor, {#blank#}5{#/blank#} told me that I would die within two years if I didn't lose weight. I didn't want to die. I wanted to see my young son grow up, and I knew {#blank#}6{#/blank#} was time to change.

    I started to eat healthy food and work out in the gym. Finally, I {#blank#}7{#/blank#} (succeed) in losing weight. Now I weigh just 19 stone. I had never been to my son's parents' evenings because I was so ashamed and scared {#blank#}8{#/blank#} my weight would lead to him being bullied. Now, {#blank#}9{#/blank#}(look) normal, I can do the things I have never been able to do, but should {#blank#}10{#/blank#}（do） as his father.

Dear Sir,

    I'm Li Hua, {#blank#}1{#/blank#} student from Class2, Grade 3. I'm writing to apply{#blank#}2{#/blank#} the position as a student volunteer.

    I really want to catch this precious opportunity because, by {#blank#}3{#/blank#}(offer) my service, I will be able to improve my organizational ability, communication skills as well as {#blank#}4{#/blank#}(confident) in speaking English in public.

    As an outgoing girl, I get along well with my classmates. {#blank#}5{#/blank#}, I have been elected as assistant to my English teacher because I have {#blank#}6{#/blank#}a good command of English. {#blank#}7{#/blank#}(successful), I {#blank#}8{#/blank#} （lend） a helping hand to her in several English activities of my class, {#blank#}9{#/blank#} have been appreciated by both teachers and classmates.

    I am sure that I can perfectly live up to your expectations. I will be grateful {#blank#}10{#/blank#} you could give me a kind consideration.

    Looking forward to your reply.

Yours truly,

Li Hua

    If {#blank#}1{#/blank#} (give) the choice, a great many people would change at least one aspect of their appearance. They would request a doctor to give them a straighter nose, {#blank#}2{#/blank#} (big) lips, and so on.

    Firstly, one's appearance is{#blank#}3{#/blank#} or her parents' blessing. After breast enlargement surgery, many women look sexier than before. {#blank#}4{#/blank#}, many of them are later diagnosed with mammary diseases. The more serious effect is {#blank#}5{#/blank#} they risk {#blank#}6{#/blank#} (be) unable to breast-feed. Secondly, the advocating {#blank#}7{#/blank#}such a practice will mislead people in the{#blank#}8{#/blank#} (judge) of beauty. The concept of beauty is quite rich in its content. It should include many virtues like honesty, diligence, and so on, which should form the real mainstream of our spiritual life. The practice and the debates about man-made beauty will confuse those who are to develop {#blank#}9{#/blank#} correct concept of beauty.

    Concerning the above possible {#blank#}10{#/blank#} (harm) the practice may bring about, I am strongly against it and advocate seeking true and natural beauty. Besides, people, especially women, should lay more attention on the cultivation of their inner hearts. The inner beauty outweighs the outside beauty in the long run.
