My friend had a chance to make a trip to Hong Kong on August 15, 2016. He had dreamed {#blank#}1{#/blank#} visiting it since his boyhood and it was the first time that he {#blank#}2{#/blank#}(be) there. The following was what he had seen.

    {#blank#}3{#/blank#} (arrive) there, he was impressed by its beautiful scenery and tall buildings. It is said that Hong Kong has the {#blank#}4{#/blank#} (many) skyscrapers (摩天大楼) in the world. Wherever he went, he saw many smiling faces. People in Hong Kong were kind, easy­going and ready to help others. Much to his surprise, he saw that people there always kept order in public {#blank#}5{#/blank#} (place). Though crowds of people were waiting for the next train at the subway station, they were talking in such {#blank#}6{#/blank#} low voice as not {#blank#}7{#/blank#} (disturb) others.

    Chinese and English are the {#blank#}8{#/blank#}(office) languages of Hong Kong. English {#blank#}9{#/blank#}(use) in governments, markets, service centers and other fields.

    Staying there for a week was a good experience for him, {#blank#}10{#/blank#} he would never forget.

    Two brothers, Herbert and James, lived together with a cat named Edgar.

    James {#blank#}1{#/blank#} (be) particularly devoted to the cat, and when he had to leave town for several days, he left Herbert careful {#blank#}2{#/blank#}(instruct) about the cat's care.{#blank#}3{#/blank#} the end of his first day away, James telephoned his brother ,“How is Edgar ?”He asked.

    “Edgar is {#blank#}4{#/blank#}(die),” Herbert answered. Then James said, “Herbert, you're insensitive(漠不关心的). You know{#blank#}5{#/blank#} close I was to Edgar. You should have broken the news to me {#blank#}6{#/blank#}(slow). When I asked about Edgar tonight, you should have said, 'Edgar's on the roof, but I have called the first department {#blank#}7{#/blank#} (get) him down.' And tomorrow when I called, you could have said the firemen were having trouble{#blank#}8{#/blank#} (take) the pet down, but you were hopeful they would succeed. Then when I called the third time, you could have told me that the firemen have done their{#blank#}9{#/blank#} (good), but unfortunately Edgar had fallen off the roof and was at the vet's(兽医站). Then when I called the last time, you could have said that {#blank#}10{#/blank#} everything possible had been done for Edgar, he had died. That's the way you should have told me about Edgar.”

    Many people keep small fish {#blank#}1{#/blank#} pets. They keep them in a tank (鱼缸) of water. The tank {#blank#}2{#/blank#} (make) of glass. People can look through it. They can see inside the tank and watch the fish.

    The fish need room. They mustn't be crowded. They need oxygen {#blank#}3{#/blank#} (breath). There must be enough water for all fish. So the size of the tank is very {#blank#}4{#/blank#} (importance).

    In the tank people put small plants {#blank#}5{#/blank#} are good for fish. They give oxygen to the water. Plants help in other ways, too. They can hide {#blank#}6{#/blank#} the plants and sleep, lay eggs there.

    The fish should {#blank#}7{#/blank#} (keep) in water all the time. Some can jump high. So the tank should be covered. This keeps the fish from {#blank#}8{#/blank#} (jump) out.

    The fish need food and should be fed every day. But if you give them too much food, it is very bad, for the extra food {#blank#}9{#/blank#} (fall) to the bottom and make the water dirty. So the fish should get just enough food and finish {#blank#}10{#/blank#} in ten minutes. Nothing should be left.

    There are all kinds of {#blank#}1{#/blank#}(festival)throughout the world，festivals to satisfy and please the ancestors，to honour some famous people {#blank#}2{#/blank#} important events，and to express people's gratitude to the God for bringing them a year of plenty. For example，Japanese observe Obon, when people go to clean graves and light incense in memory of their ancestors. {#blank#}3{#/blank#} India，October 2 is a national festival to honour Mohandas Gandhi，who helped India become an {#blank#}4{#/blank#}(depend) country. And in China the Spring Festival, {#blank#}5{#/blank#} is celebrated in January or February，is the {#blank#}6{#/blank#}(much)energetic and important because it is a festival that {#blank#}7{#/blank#}(look) forward to the coming of spring. Why are all these festivals everywhere？Because during the festivals，people can get together {#blank#}8{#/blank#}( eat), drink and have fun with each other, {#blank#}9{#/blank#}(forget) all the {#blank#}10{#/blank#}(day) struggles and demands for a while.

Yungang Grottoes (石窟) in Datong, Shanxi Province, are a world cultural heritage (遗产) site with a history that {#blank#}1{#/blank#} (go) back more than 1,500 years. In Yungang's 45 big grottoes and more than 200 small grottoes, roughly 59,000 figures of the Buddha, {#blank#}2{#/blank#} (be) a priceless treasure of human culture.

{#blank#}3{#/blank#}because of the effects of climate change and natural disasters, the grottoes face damage year after year. Thanks to {#blank#}4{#/blank#} (advance) digital technology, researchers are busy "duplicating" (复制) the Yungang Grottoes in an attempt to preserve the precious cultural relics (遗物). Employing 3D laser scanning technology, the researchers{#blank#}5{#/blank#} (digital) record the shapes, colors and other fine details of the grottoes and later reproduce{#blank#}6{#/blank#}by using 3D printing technology.

The new technology could enable more people{#blank#}7{#/blank#} (access) the cultural relics despite the distance. In June, 2020, the Zhejiang University Cultural Relics Research Institute and Yungang Grottoes Research Institute together "copied and pasted" Cave No. 12 of the Yungang Grottoes for an{#blank#}8{#/blank#} (exhibit) in Hangzhou, in which is the world's first 3D-printed 1:1 "copy" of a grotto.

These Yungang{#blank#}9{#/blank#} (researcher) attempt is a good example of technology helping to preserve cultural heritage. It is hoped{#blank#}10{#/blank#}the new digitalized technologies will facilitate the "rebirth" of the cultural relics, and bring them to more places worldwide.
