In London, there are many so-called pop-up shops(流动商店). Why they get such a name is that they are just temporary {#blank#}1{#/blank#} (arrange).

    Pop-up shops first appeared in the UK in the early 2000s. They were{#blank#}2{#/blank#} (origin)a way for small companies to rent small space in great locations.

    In 2008，many businesses had to shut down. Shops and some offices{#blank#}3{#/blank#} (leave)empty when people stopped{#blank#}4{#/blank#} (run) them. Smart businessmen occupied some of them quickly because they could start a business with much {#blank#}5{#/blank#} (low) risk. The temporary nature of a pop一up gave them the opportunity{#blank#}6{#/blank#} ( test) a product and develop a customer base. Being small made {#blank#}7{#/blank#} easier for pop-ups to expand if they were successful.

    Pop-up shops can take many different forms. They might be temporary shops in the high street or a shopping centre. hey might be simple market stalls. According to a 2014 report made {#blank#}8{#/blank#}the Centre of Economic and Business Research, the pop-up industry was worth £2. 1 billion {#blank#}9{#/blank#} it is expected to grow by 8.4% this year.

    Almost anything{#blank#}10{#/blank#} can be on a high street can also be a pop-up. In an age of fast changing habits, the pop-up idea might be here to stay.

    Born in England in 1944, Ian Wilmut{#blank#}1{#/blank#}(know)as the leader of the research group that first cloned a female lamb {#blank#}2{#/blank#}(call)Dolly in 1996. Dolly became famous and pictures of her appeared on the{#blank#}3{#/blank#}(cover)of magazines all over the world. The{#blank#}4{#/blank#}(possible)of reproduction without a male and female being involved also made her the focus of a moral debate. For scientists, however, the cloning of dolly using the DNA of an adult cell was a breakthrough {#blank#}5{#/blank#}showed the cloning of special animals was possible.

    However,{#blank#}6{#/blank#}Wilmut thinks unlikely is human cloning. He says {#blank#}7{#/blank#}(undertake)the procedure with humans would require 29 surrogate(替代的)mothers and 300 eggs. Of those 29,28 would be bound {#blank#}8{#/blank#}(experience)failure and suffer physically and emotionally. He says he is also concerned about the psychological and{#blank#}9{#/blank#}(society)consequences a cloned might have to go through. For these reasons, he is not {#blank#}10{#/blank#}favor of it.

    Xi made the praise in a letter {#blank#}3{#/blank#} (write) to the students in Beijing's Bayi School on Saturday.

    Three months ago, Xi returned to his high school, to visit a laboratory and talk to teachers and students {#blank#}6{#/blank#} were designing the small satellite. The president said he was {#blank#}7{#/blank#} (extreme) glad to know that the satellite designed by the students would be launched and called on them to become {#blank#}8{#/blank#} (build) of the country.
