This week, we're preparing for one of the newest {#blank#}1{#/blank#}(tradition) events in our country: Black Friday. It's that crazy gathering of retail (零售)-related violence, a time{#blank#}2{#/blank#}stores offer once-a-year promotional sales to set off the customers' greediness and jump-start the Christmas shopping season with a sudden activity in a {#blank#}3{#/blank#} (crowd) space.

    The general feeling has been set by the Hamleys Christmas Toy Parade in London, in which 800,000 people ran into Regent Street, apparently attracted by {#blank#}4{#/blank#}possibility of a “meet-and-greet” with Peppa Pig that sadly {#blank#}5{#/blank#}(have) to be cancelled at the last moment on safety grounds. As it was, a middle-aged woman {#blank#}6{#/blank#}(report) had to be taken to hospital after {#blank#}7{#/blank#} (knock) to the ground in a fight with another woman.

    For the people who dislike shopping, such as me, any day with shopping in it is a black day, and Black Friday is the most worrying {#blank#}8{#/blank#}all. However, I can see the reasoning for retailers. Why spend a lot of money on newspaper ads, when you can offer 50 iPhone Xs at £5 each to the first fifty{#blank#}9{#/blank#}(consume)? The related media {#blank#}10{#/blank#} (cover) of the resulting disorder is, as they say, priceless.

    One morning, I was waiting at the bus stop, worried about {#blank#}1{#/blank#}(be) late for school. There were many people waiting at the bus stop, {#blank#}2{#/blank#} some of them looked {#blank#}3{#/blank#}(disappoint). When the bus finally came, we all hurried on board. I got a place next {#blank#}4{#/blank#} the window, so I had a good view of the sidewalk. A boy on a bike {#blank#}5{#/blank#}(catch) my attention. He was riding beside the bus and waving his arms. I heard a passenger behind me shouting to the driver, but he refused {#blank#}6{#/blank#}(stop) until we reached the next stop. Still, the boy kept {#blank#}7{#/blank#}(ride). He was carrying something over his shoulder and shouting. Finally, when we came to the next stop, the boy ran up to the door of the bus. I heard an excited conversation. Then the driver stood up and asked, “{#blank#}8{#/blank#} anyone lose a suitcase at the last stop?” A woman on the bus shouted. “Oh dear! It's {#blank#}9{#/blank#}(I).” She pushed her way to the driver and took the suitcase thankfully. Everyone on the bus began talking about what the boy had done, and the crowed of strangers {#blank#}10{#/blank#}(sudden) became friendly to one another.

    Chinese researchers have planned to build an airport in Antarctica in November. The Chinese {#blank#}1{#/blank#} (be) not very used to flying to the southernmost continent, because the country s first polar plane, the Snow Eagle 601, {#blank#}2{#/blank#} (put) into use only three years ago.

    Before the Snow Eagle 601, Chinese researchers traveled to the ice-covered land by ship, which took significantly {#blank#}3{#/blank#} (long) than flying. There are currently more than 20 airports in Antarctica, but none of them belong to China. The Snow Eagle 601 has to rely on Russian airports {#blank#}4{#/blank#} (take) off and land. That's {#blank#}5{#/blank#} the Chinese researchers decided to build their own. Building an airport in Antarctica is very different from building one elsewhere. The continent is covered by a {#blank#}6{#/blank#} (constant) moving layer of ice, so the builders must find somewhere that moves at the slowest possible pace and in a {#blank#}7{#/blank#} (fix) direction.

    The builders managed to find a spot back in early 2017 following {#blank#}8{#/blank#} tough measuring process that took place in the storm-like polar winds. The next problem is the snow. The soft nature of snow makes {#blank#}9{#/blank#} a bad material for a runway. So the builders must use road roller-like {#blank#}10{#/blank#} (machine) to press the snow, which can be very time-consuming in extreme coldness.
