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).

    Red is a particularly popular color in China. A pair of red shoes — {#blank#}1{#/blank#}they are for sports, dances or just fashion — is a must-have for every Chinese woman's shoe collection. For most Chinese brides, red shoes should also be worn {#blank#}2{#/blank#} their big day.

    As women's feet {#blank#}3{#/blank#} (connect) with female attraction, red shoes often emphasize this aspect {#blank#}4{#/blank#} convey a special beauty. In some classic Chinese novels, there are{#blank#}5{#/blank#} (describe) of charming women in red silk shoes.

    If you wear a dark dress in cold {#blank#}6{#/blank#} (season), a pair of red shoes can raise your ensemble（整套服装）to a {#blank#}7{#/blank#} (high) level. They can also go with different levels of red color,  {#blank#}8{#/blank#} (give) the wearer a lively and joyful look.

    {#blank#}9{#/blank#} (sure) red will always be a beloved color for designers, and red shoes have also become a choice for many supermodels. If you are also a fan of this {#blank#}10{#/blank#} (energy) color, consider wearing a pair of red shoes for every Chinese Lunar New Year!

    A computer program has beaten a human player at the ancient Chinese board game Go（围棋）. It marked an important advance for the {#blank#}1{#/blank#} (develop) of artificial intelligence. The program, {#blank#}2{#/blank#} (call) Alpha Go, had taught itself how to win. It beat the European player in all five games of a match in October. The developers say {#blank#}3{#/blank#} (it) learning ability may someday let computers help solve real world problems. Those could include making medical diagnoses and {#blank#}4{#/blank#} (explore) scientific research.

    Previous computers have beaten humans in other games. But among classic games, Go has long been viewed as the most challenging game for artificial intelligence to master. Therefore, many people find it {#blank#}5{#/blank#}(accept) when AlphaGo won the human player.

    Go involves two players who take turns putting markers on a checkerboard-like grid (格子).  Players obtain the opponent's pieces {#blank#}6{#/blank#} surrounding them. The rules are simple, {#blank#}7{#/blank#} playing it is not. It's {#blank#}8{#/blank#} (probable) the most complex game ever created by humans.

    Martin Mueller, a computing science professor, {#blank#}9{#/blank#} (work) on Go programs for 30 years. He once said, "The new program is really a big step up from everything else that we've seen. It's a very {#blank#}10{#/blank#} (amaze) piece of work."

    Once there lived a rich man{#blank#}1{#/blank#}wanted to do something for the people of his town.{#blank#}2{#/blank#} first he wanted to find out whether they deserved his help.

    In the centre of the main road into the town, he placed{#blank#}3{#/blank#}very large stone. Then he {#blank#}4{#/blank#}(hide) behind a tree and waited. Soon an old man came along with his cow.

    “Who put this stone in the centre of the road?” said the old man, but he did not try to remove the stone. Instead, with some difficulty he passed around the stone and continued on his way{#blank#}5{#/blank#}man came along and did the same thing; then another came, and another. All of them complained about the stone but not tried to remove {#blank#}6{#/blank#}. Late in the afternoon a young man came along. He saw the stone,{#blank#}7{#/blank#}(say) to himself: “The night{#blank#}8{#/blank#}(be) very dark. Some neighbors will come along later in the dark and will fall against the stone.”

    Then he began to move the stone. He pushed and pulled with all his {#blank#}9{#/blank#}(strong) to move it. How great was his surprise at last!{#blank#}10{#/blank#} the stone, he found a bag of money.
