Singles' Day falls on November 11th every year in China, {#blank#}1{#/blank#} is recognized as a day for people who have no girlfriend or boyfriend. Couples and lovers have Valentine's Day in {#blank#}2{#/blank#} (celebrate) of their love, but how about the singles? There must be a day they can celebrate even without a partner. That's {#blank#}3{#/blank#} people created Singles' Day.

    On Singles' Day many singles choose to say goodbye to their single lives, {#blank#}4{#/blank#} (attend) blind date（相亲） parties, and some people even decide to get{#blank#}5{#/blank#} (marry) to strangers. {#blank#}6{#/blank#} this day has recently become more of a time for shopping, because many shops online will give customers great discount {#blank#}7{#/blank#} (promote) their goods.

    More and more people are {#blank#}8{#/blank#} (will) to shop online to get what they want, and I am one of them. I just can't help buying things {#blank#}9{#/blank#} I need them or not. {#blank#}10{#/blank#} (honest) speaking, some of the things that I bought have been put aside forever in my closet.

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.
