This passage mainly tells us the {#blank#}1{#/blank#}(valuable) of a person. A collage student in this passage {#blank#}2{#/blank#} (choose)the wrong major and became more and more frustrated. He thought he couldn't be successful and achieve {#blank#}3{#/blank#}dream. {#blank#}4{#/blank#}, he only liked to listen to Yang' s class and never  {#blank#}5{#/blank#}(absence). He put a note and showed his value to Yang. One day, Yang told him the {#blank#}6{#/blank#}(different) between different potatoes. So this student understood the life and became successful.

    From this passage, I think, in our lives, we shouldn't move back when we have trouble with our study or work. {#blank#}7{#/blank#} (contrary), we must try hard to make our lives better and be {#blank#}8{#/blank#}(value) one in these common people. If we do, like this, we will show our value by ourselves and be found by top people. So we may change our destiny and become {#blank#}9{#/blank#}(success)

    All in all, I hope every one can show their value lively and {#blank#}10{#/blank#}(life)a successful life. Please remember：Be a potato, but be the best!

    Many people travel during the holiday season but do not make sure that their houses and homes {#blank#}1{#/blank#} (protect). Crime goes up {#blank#}2{#/blank#}(rapid) during the winter and summer holiday seasons. Here are some things that you should keep in mind when you go on a holiday.

    Always give {#blank#}3{#/blank#}(strange) the feeling that you are at home. Have the snow {#blank#}4{#/blank#}(clean) off your stairs or out of your driveway during the winter season. You might ask someone to park {#blank#}5{#/blank#} car in your driveway.

Tell your newspaper deliverer that you are not at home. {#blank#}6{#/blank#}(have) a pile of newspapers and other mail on your doorsteps tells people that are not at home, so you could also have a neighbor {#blank#}7{#/blank#} a relative get your mail every day.

    Fix a timer in some of your rooms {#blank#}8{#/blank#} turns lights on and {#blank#}9{#/blank#}during different time of the day. Some TVs also comes with a timer that you could set to be turned on during certain time. Have a sensitive light outside your house that {#blank#}10{#/blank#}(keep) thieves away when you are not at home.

    Almost all the ice covering the Bering Sea has melted(融化), scientists have confirmed, {#blank#}1{#/blank#} (throw) communities living around {#blank#}2{#/blank#} (it) shores into disorder. The region's ice cover {#blank#}3{#/blank#} (normal) lasts for at least another month, and this year it has disappeared earlier than any other year except 2017.

    Living in {#blank#}4{#/blank#} northern Pacific Ocean between Alaska and Russia, the Bering Sea is experiencing the climate change and has drawn attention this year for record-breaking levels of winter melting. In February, rising Arctic temperatures {#blank#}5{#/blank#} (lead) to around half the region's disappearing in the space of two weeks.

    A report {#blank#}6{#/blank#} (send) by the International Arctic Research Centre at the University of Alaska Fairbanks has outlined the real-world effects of these surprising environmental {#blank#}7{#/blank#} (change) on the many communities {#blank#}8{#/blank#} live in the Bering Sea region.

    In their report, the International Arctic Research Centre scientists wrote that while not every year will be as bad as this one, ice {#blank#}9{#/blank#} (form) is likely to remain low if the Bering Sea's waters remain warm. They also warn that communities will need to "prepare for more winters {#blank#}10{#/blank#} low sea ice and stormy conditions".

    An umbrella is what we easily forget and leave behind in our daily life. When the weather is fine, we certainly don't think of it; only when it's raining, we'll carry it purposefully. But as soon as the rain stops, most likely we'll forget {#blank#}1{#/blank#} we've put it. It has to wait patiently and pitifully for {#blank#}2{#/blank#} owner to claim it, otherwise it'll remain alone as a deserted umbrella. Once I suddenly found my longtime used umbrella "disappeared". I really {#blank#}3{#/blank#} (regret) quite some time for my own carelessness. Several days later, out of my {#blank#}4{#/blank#} (expect), I saw it quietly stand in a corner of the house where I worked. I was extremely glad to regain it. Looking carefully at it, though it was so familiar {#blank#}5{#/blank#} me, I found for the first time that its plastic handle {#blank#}6{#/blank#} (wear) out as a result of repeated rain-wash for years. I sought for it only when I needed it. It occurred to me that I should have paid {#blank#}7{#/blank#} (much) attention to it.

    It sets me {#blank#}8{#/blank#} (think). Around us there is always a person giving us support in silence just like {#blank#}9{#/blank#} old umbrella that protects us from the rain or any bad weather. Will you think of those individuals {#blank#}10{#/blank#} have helped you get through difficulty when you are leading a comfortable life?

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.
