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

    In the center 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 center 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 will be very dark. Some {#blank#}8{#/blank#} (neighbor) 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，only to find a bag of money under the stone. Imagine {#blank#}10{#/blank#} surprised he was!

    Typhoon Mangkhu attacked the Pearl River Delta on Sunday,{#blank#}1{#/blank#} (leave) a trail of damage, flooding and injuries in its wake and forcing the closure of schools, markets and most public s{#blank#}2{#/blank#} across the area.

    After claiming at {#blank#}3{#/blank#}29 lives in the Philippines, the {#blank#}4{#/blank#}(destroy) storm has caused 4 deaths in Guangdong.

    Hong Kong Observatory kept its highest No 10 Hurricane Signal（十号风球） in effect for 10 hours from morning to evening on Sunday.

    In the Hong Kong Special Administrative Region, strong winds and heavy rain left more than 213 people{#blank#}5{#/blank#}(injure) , and over 1,200 people sought refuge（应急避难） in temporary government shelters.

    According to the Guangdong Meteorological Observatory, Mangkhut will c{#blank#}6{#/blank#}to cause heavy rain and bring strong winds to the province{#blank#}7{#/blank#}Thursday.

    E{#blank#}8{#/blank#} said the warm seawater in the South China Sea helped Mangkhut maintain its strength after an {#blank#}9{#/blank#}(early) landfall in the Philippines.

    Brave and {#blank#}1{#/blank#}(intelligence), the tiny mouse from the US cartoon series Tom and Jerry is loved and remembered by fans worldwide.

    Recently, scientists from Britain and Canada have created super-clever mice by {#blank#}2{#/blank#}(change) a single gene (基因). In the study, {#blank#}3{#/blank#}(research) changed one of the mice's genes to stop the PDE4B enzyme (酶), a substance found in the human brain, {#blank#}4{#/blank#} working.

    After that, they ran several tests on the {#blank#}5{#/blank#}(behave) and found they tended to learn{#blank#}6{#/blank#}(fast), remember events for longer and {#blank#}7{#/blank#}(solution) difficult problems better than normal mice. The mice also suffered less anxiety (焦虑) and showed {#blank#}8{#/blank#} fear of cats, their natural enemy.

    A team from the UK's Leeds University is now trying developing drugs (药品){#blank#}9{#/blank#} could block the PDE4B enzyme. {#blank#}10{#/blank#}(hope), the drugs could help with treatments for brain conditions such as Alzheimer's disease (老年痴呆症).

    The story goes {#blank#}1{#/blank#} two friends are walking through the desert. During some point of the journey they have {#blank#}2{#/blank#} argument, and one friend beats the other one in the face.

    The one is hurt, but {#blank#}3{#/blank#} saying anything, he writes in the sand: "Today my best friend beats me in the face."

    They keep on walking {#blank#}4{#/blank#} they find an oasis (绿洲) and they decide to take a bath. The one who{#blank#}5{#/blank#} (beat) gets stuck in the mire (泥潭) and starts to sink, but {#blank#}6{#/blank#} (fortune) the friend saves him.

    After he recovers from the near {#blank#}7{#/blank#} (drown), he writes on a stone: "Today my best friend saves my life."

    His friend asks him, "When I hurt you, you wrote in the sand, but now you write on a stone. Why?"

    He {#blank#}8{#/blank#}(reply): "When someone hurts us, we should write it down in the sand, the winds of {#blank#}9{#/blank#} (forgive) can rub it away. But when someone does something good to us, we must carve {#blank#}10{#/blank#} on a stone, therefore, no wind can ever erase it."

Learn to write your hurts in the sand and to engrave your benefits on the stone.
