Once upon a time, there was a man from the State of Chu who loved his sword very much. One day, he was sitting in a boat{#blank#}1{#/blank#}(prepare)to cross a river, when he accidentally dropped his sword into the water.{#blank#}2{#/blank#}his ship moving fast on and the water running, the people on board reminded that he should go into the water to find his beloved sword back. The man felt in great{#blank#}3{#/blank#}(anxious)too. However, he turned a deaf ear to that and instead, he  {#blank#}4{#/blank#}(immediate) took out a knife and made a notch(刻痕)on the side of the boat{#blank#}5{#/blank#}his dear sword fell. The people wondered why he did so. He said proudly the notch could help{#blank#}6{#/blank#}(get)his sword back. Shortly after the   {#blank#}7{#/blank#}(arrive)at the shore, he entered the water just beneath the notch he made. Though{#blank#}8{#/blank#}(spend)rather a long time, he returned empty-handed. Without doubt, he was laughed at in public and his story became{#blank#}9{#/blank#}well-known joke in China.

    Today the idiom {#blank#}10{#/blank#}(relate)to the story is used to describe a person who stick to rigid rules without considering a changing environment or describes an action made pointless by changing circumstances.

    I had an impressive trip to the Huashan Mountain last summer vacation. The scenery of the mountain is so beautiful and so different{#blank#}1{#/blank#} even now, whenever I close my eyes, I feel the breathtaking scenery in front of{#blank#}2{#/blank#} eyes.

    Although the mountain{#blank#}3{#/blank#} (stand) just 2,100 meters tall, it's known as one of the most difficult mountains to climb. There are cable cars(缆车) to take, but visitors are advised{#blank#}4{#/blank#} (go) up on foot. Only in this way can you see {#blank#}5{#/blank#} special the rocks are and what danger you place yourself in. Climbers make their way along very narrow paths up the mountain{#blank#}6{#/blank#}(face) the deep cliff (悬崖), with the help of{#blank#}7{#/blank#}iron chain. Every visitor is required to wear a safety belt，{#blank#}8{#/blank#} makes sure that he can enjoy the fantastic view without fear of falling.

    Besides the{#blank#}9{#/blank#} (nature) beauty, the Huashan Mountain is also known {#blank#}10{#/blank#} its rich cultural relics. The way up to the mountain-top is also a trip to go over the Chinese history. If you have never been to such a great place, set it as a must in your calendar of this year!

    Charles Richard Drew {#blank#}1{#/blank#}(be) a famous African — American doctor and scientist. His work on blood banks helped save thousands of{#blank#}2{#/blank#}(life) during World War II.

    Charles Richard Drew {#blank#}3{#/blank#}(bear) in 1904 in Washington D.C. His main interest was in sports when he was young. He won many medals for {#blank#}4{#/blank#}(swim). Later, he turned to basketball and football. During college, Charles became interested in medicine. He attended Medical School at McGill University in Canada. In 1933, he received {#blank#}5{#/blank#}(he) doctor of Medicine Degree.

    As a doctor and a researcher, Charles was absorbed in research on blood transfusions（输血）. Through his experiments, he found that blood plasma（血浆）could be {#blank#}6{#/blank#}(success) used instead of whole blood. He {#blank#}7{#/blank#}(write) up the results in a published report.

    During World War II, Charles worked with the British. He helped them develop the blood bank. He organized the collection{#blank#}8{#/blank#} processing of blood plasma from different hospitals. These life-saving plasmas cured wounded people in the war. He also helped the American Red Cross develop a blood bank.

    Charles died in 1950 as {#blank#}9{#/blank#} result of a car accident. After his passing away, he received many honors. Many schools and institutions were named {#blank#}10{#/blank#} him.

    Chinese researchers have planned to build an airport in Antarctica in November. The Chinese {#blank#}1{#/blank#} (be) not very used to flying to the southernmost continent, because the country s first polar plane, the Snow Eagle 601, {#blank#}2{#/blank#} (put) into use only three years ago.

    Before the Snow Eagle 601, Chinese researchers traveled to the ice-covered land by ship, which took significantly {#blank#}3{#/blank#} (long) than flying. There are currently more than 20 airports in Antarctica, but none of them belong to China. The Snow Eagle 601 has to rely on Russian airports {#blank#}4{#/blank#} (take) off and land. That's {#blank#}5{#/blank#} the Chinese researchers decided to build their own. Building an airport in Antarctica is very different from building one elsewhere. The continent is covered by a {#blank#}6{#/blank#} (constant) moving layer of ice, so the builders must find somewhere that moves at the slowest possible pace and in a {#blank#}7{#/blank#} (fix) direction.

    The builders managed to find a spot back in early 2017 following {#blank#}8{#/blank#} tough measuring process that took place in the storm-like polar winds. The next problem is the snow. The soft nature of snow makes {#blank#}9{#/blank#} a bad material for a runway. So the builders must use road roller-like {#blank#}10{#/blank#} (machine) to press the snow, which can be very time-consuming in extreme coldness.
