Are you facing a situation that looks impossible to fix?

    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.

    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 (信用卡) 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 (转变)，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).

    Dragon Head Raising Day,{#blank#}1{#/blank#} falls each year on the second day of the second lunar month, is one of the Chinese traditional festivals. As the proverb goes: “The dragon is awaked,{#blank#}2{#/blank#} (raise) his head”. On this day, dragons, a prominent totem (图腾) in Chinese culture raise {#blank#}3{#/blank#} (they) heads with the sound of thunder. Around this time, the earth {#blank#}4{#/blank#} (burst) with life. Grass and trees are beginning to shoot up. In ancient China, people {#blank#}5{#/blank#} (pray) the dragon god beside a river or a lake for the precious spring rains to breed their crops.

    {#blank#}6{#/blank#} (tradition), food eaten on this day was renamed after parts of the dragon. For instance, wontons were called “dragon's eyes.” The special {#blank#}7{#/blank#} (food) usually eaten on this day include dragon's scales, popcorn and pig's head.

    In Shanxi, people get their hair {#blank#}8{#/blank#} (cut) in a symbolic move to remove the old and embrace the new. In {#blank#}9{#/blank#} countryside in Hebei Province, people would fetch water from a well at dawn. It was believed {#blank#}10{#/blank#} on this day the well was full of dragon eggs which would bring the collector good harvest.

    Johnny Carson began his career in television in his {#blank#}1{#/blank#} (twenty). First he worked at local stations in Nebraska. Several years {#blank#}2{#/blank#} (late), he moved to Los Angeles, California. It was “The Tonight Show” {#blank#}3{#/blank#} made Johnny Carson famous for thirty years. He became {#blank#}4{#/blank#} most popular star of American television. He{#blank#}5{#/blank#} (call) “the king of late night”. Critics  (评论家) said Americans from all parts of the country liked him and {#blank#}6{#/blank#} (feel) they knew him. He did not take his fame {#blank#}7{#/blank#} (serious). Carson's special skill was his sense of humor. Audiences laughed at his jokes {#blank#}8{#/blank#} he made at the beginning of his show. However, sometimes they laughed even {#blank#}9{#/blank#} (hard) at the jokes that failed. He was the most powerful performer on television. Many comedians and singers became successful after {#blank#}10{#/blank#} (appear) on “The Tonight Show”.

    The way you walk may be determined by your daily schedule, and it may also reflect your personality. The {#blank#}1{#/blank#} (choose) you make can tell something about your inner thoughts. At least, that's{#blank#}2{#/blank#} science has proved. Lately, researchers{#blank#}3{#/blank#} (observe) the way that people walk and how it relates to their personalities. Available online via Sage Journals, the study examines both the walking styles and personalities of 15,000 adults aged from 25 to 50. According to the study, when {#blank#}4{#/blank#} (face) with the new challenges, fast walkers are more likely to be active while quiet people tend to walk more slowly. Meanwhile, the study has also found{#blank#}5{#/blank#} (power) evidence that walking speed in adulthood reflects the individual's personality. However, speeding up your walking pace can't {#blank#}6{#/blank#} (instant) make you the life of the party, {#blank#}7{#/blank#} means that you needn't change your personality. Actually, there are {#blank#}8{#/blank#} (hide) strengths of being a quiet person as well as an active one. Make the most of your strengths, {#blank#}9{#/blank#} you can be successful regardless of which type you fall into and {#blank#}10{#/blank#} fast or slowly you walk.

    What makes the sea tum red and causes thousands of fish to die？As far back as anyone could remember, the blame was placed on the "red tides." In 1947, scientists finally connected the red tides with a microscopic sea organism(有机体){#blank#}1{#/blank#}(call)the dinoflagellate.

    The dinoflagellate is so tiny {#blank#}2{#/blank#} 6, 000 of these organisms may be contained in {#blank#}3{#/blank#} single drop of water. It stands on the borderline between plant and animal in its classification, it produces its own food, as plants do. But it moves {#blank#}4{#/blank#}(free)and eats other organisms, as animals do.

    Dinoflagellates are normally only one of the many kinds of organisms found in plankton. Plankton is the name given to all very small {#blank#}5{#/blank#}(form)of sea life. However, when the air and water {#blank#}6{#/blank#}(be)calm and warm, dinoflagellates multiply with {#blank#}7{#/blank#}(amaze)sped. The surface of the water appears {#blank#}8{#/blank#}(cover)with a red carpet.

    The dinoflagellates give off a poison. Many fish die. Their bodies are washed up on the beach. Beaches are not fit {#blank#}9{#/blank#} any use. Fish that are not killed may become {#blank#}10{#/blank#}(poison)to animals or people who eat them. Commercial fishing comes to a stop.

    As dinoflagellates consume all the food and oxygen in an area, they die. After a time, the sea returns to normal. But when conditions are right, the red tide comes again.

    China has once again showed its ability to change{#blank#}1{#/blank#}world with its "four great new inventions"-high-speed rail, electronic payment, shared bicycle, and online shopping.

    China's new-generation high-speed train, the Fuxing Hao, is now one of the{#blank#}2{#/blank#}(fast) trains in the world, which can travel at a speed of 350 km/h. Apart from high-speed rail, the other three{#blank#}3{#/blank#}(improve) people's lives over the last decade. Bike sharing, for example, has made{#blank#}4{#/blank#}much more convenient for people to get around in daily life. When riding a shared bike, you can stop{#blank#}5{#/blank#}(buy) and eat whatever you want. What's more, cashless payment has grown into a{#blank#}6{#/blank#}(choose) for Chinese people. Bio-payments are{#blank#}7{#/blank#}(gradual) replacing passwords to become the primary means of payment in future. As high as 60.3 percent of payments made by Alibaba's T-mall and Taobao{#blank#}8{#/blank#}(accomplish) by users' scanning their fingerprints or faces instead of entering passwords last year.

    The four innovative ways of life are most{#blank#}9{#/blank#}(attract) to a great number of foreign people, most of{#blank#}10{#/blank#}wish their countries would achieve great progress like China in terms of technological achievements.
