—I'm sorry, but by then I {#blank#}1{#/blank#}(fly) to Beijing. How about five?

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.

    Ever wondered how many calories are in the human body? Or ever wondered why old people have {#blank#}1{#/blank#} (big) ears than they used to? The winners of Ig Nobel Prizes (搞笑诺贝尔奖) have got the answers.

    He Ig Nobel Prizes, founded in 1991, are to honor achievements {#blank#}2{#/blank#} first make people laugh, and then make them think, The ceremony {#blank#}3{#/blank#} (take) place at Harvard University every year. Winners' acceptance {#blank#}4{#/blank#}(speech) are limited to 60 seconds, {#blank#}5{#/blank#} (strict) policed by an eight-year-old girl.

    The honored research might seem ridiculous {#blank#}6{#/blank#} first sight, but that doesn't mean it lacks scientific value. For example, the research in 2006 on why dry spaghetti tends to break into more than two pieces was important {#blank#}7{#/blank#} (discover) failure in bridge spans (跨度) or human bones And a follow-up paper {#blank#}8{#/blank#} (publish) by MIT physicists several years later. But people are more likely to read about {#blank#}9{#/blank#} (break) spaghetti than to read an academic paper. Even when there is no immediate usefulness, {#blank#}10{#/blank#} is still good to encourage people to observe and think.
