My grandfather is a {#blank#}1{#/blank#}(retire) worker. On summer evenings, we often sat together outside the house {#blank#}2{#/blank#}(enjoy) the cool air. It  was the time that he told me lots of his experiences before liberation.

        When my grandfather was fourteen years old, he worked in a coal mine. One day, when he and his two workmates were working in the tunnel, an{#blank#}3{#/blank#}(fortune) thing suddenly happened. A part of the tunnel fell down, and they were shut init. They had no food {#blank#}4{#/blank#}(eat). When they were hungry, they only drank some water there. It was very cold in it. In order to keep warm, they hugged one another. In the darkness, they didn't know whether it was day{#blank#}5{#/blank#}night, they only felt they had stayed there for a very long time. They were too hungry to speak or move, and thought they{#blank#}6{#/blank#}(die). At last, the tunnel{#blank#}7{#/blank#}(dig) through. They weresaved. They had been there for fourteen days! My grandfather said they weren't let out at once. If{#blank#}8{#/blank#}, they would have died. They were kept at the entrance to the tunnel {#blank#}9{#/blank#}it was very dim, and they were fed {#blank#}10{#/blank#} some thin porridge. After a day or two, they had recovered a bit, and they were helped out.

    {#blank#}1{#/blank#}we all know, cultural relics belong {#blank#}2{#/blank#}the people all over the world. Nowadays, more and more people are interested in the topic about {#blank#}3{#/blank#}to protect cultural relics such as places of interest, old city {#blank#}4{#/blank#}(wall), folk arts and so on. Some even advise {#blank#}5{#/blank#}(devote) to new culture exhibitions in order to educate the public. As {#blank#}6{#/blank#}matter of fact, the Chinese government has been {#blank#}7{#/blank#}(concern) about the topic and {#blank#}8{#/blank#}(take) measures. At the same time, more and more foreigners are coming to enjoy Chinese culture,{#blank#}9{#/blank#}we are sure the interest in Chinese relics abroad will be {#blank#}10{#/blank#}(great).

    Fake news has long been {#blank#}1{#/blank#} serious problem, and social media {#blank#}2{#/blank#} (blame) for allowing fake news stories to spread. US tech{#blank#}3{#/blank#} (company) Facebook and Google have been using {#blank#}4{#/blank#} (analyze) technology to fact-check stories and add labels {#blank#}5{#/blank#} dubious (可疑的) ones to warn their readers.

    But recently a survey {#blank#}6{#/blank#} (find) that as many as 60 percent of people in the US still think that not enough is being done{#blank#}7{#/blank#} (keep) internet users away from fake news. According to Eric Carvin, social media editor at the Associated Press, {#blank#}8{#/blank#}(fight) fake news is like “whack-a-mole (打地鼠游戏)”, she said, {#blank#}9{#/blank#} means that for now, we'll just have to rely on {#blank#}10{#/blank#} (we) common sense to decide what's real and what isn't.

    Chinese President Xi Jinping has praised a group of middle school students for their efforts in satellite design. He said he was pleased with their curiosity and bravery in {#blank#}1{#/blank#}(science) exploration. The president also wished the teachers and students in Bayi School {#blank#}2{#/blank#}happy new year.

    Xi made the praise in a letter {#blank#}3{#/blank#}(write) to the students in Beijing's Bayi School on Saturday. A small satellite designed and developed by them {#blank#}4{#/blank#}(send) into space last Wednesday at Taiyuan Satellite Launch Center {#blank#}5{#/blank#} it was designed to operate in orbit (轨道) for 180 days.

    Three months ago, Xi returned to his high school, to visit a laboratory and talk to teachers and students {#blank#}6{#/blank#}were designing the small satellite. The president said he was {#blank#}7{#/blank#} (extreme) glad to know that the satellite designed by the students would be launched and called on them to become {#blank#}8{#/blank#}(build) of the country. Xi warmly encouraged the students {#blank#}9{#/blank#}(study) science and contribute to the development of China. He hoped that the students would keep hungry for knowledge and develop {#blank#}10{#/blank#}(they) national spirit.
