Americans are proud of their variety and individuality, yet they love and respect few things more than a uniform, whether it is the uniform of {#blank#}1{#/blank#} elevator operator or the uniform of a five-star general. Why are uniforms so popular there?

    Among the arguments for uniforms is that most uniforms look more {#blank#}2{#/blank#} (profession) than civilian (百姓的) clothes. People expect superior quality from a man {#blank#}3{#/blank#} wears a uniform. The television repairman wearing a uniform tends {#blank#}4{#/blank#} (inspire) more trust. Faith {#blank#}5{#/blank#} the skill of a garage worker is increased by a uniform. Uniforms also have many practical {#blank#}6{#/blank#} (benefit). They save on other clothes and laundry bills. They are  often {#blank#}7{#/blank#} (comfortable) than civilian clothes. Among the arguments against uniforms {#blank#}8{#/blank#} (be) their lack of variety and the loss of individuality. {#blank#}9{#/blank#} there are many types of uniforms, the wearer of any particular typeis generally stuck with it, without change. When people look alike, they will think, speak, and act {#blank#}10{#/blank#} (similar).

    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.

    Once, a rich man was near death. He was very upset because he had worked so hard for his money {#blank#}1{#/blank#} he hoped he could take it with him to heaven. So he prayed to God he might be able to take some money with him.

    {#blank#}2{#/blank#} angel heard his pray and appeared. “Sorry, {#blank#}3{#/blank#}  you can't take your wealth with you.” The man begged the angel to speak to God to see {#blank#}4{#/blank#} he might break the rules. The angel reappeared and said that God could allow him to take one suitcase. Excitedly, the man gathered his suitcase and filled it {#blank#}5{#/blank#} pure gold bars.

    Afterward, he died and showed up in heaven to greet St. Peter. {#blank#}6{#/blank#}  (see) the suitcase, St. Peter said, “Hold on, you can't bring that here!” The man explained that he had God's {#blank#}7{#/blank#} (permit). St. Peter checked it out, came back and said, “You are right. You are allowed one carry-on bag, but I'm supposed to check its contents {#blank#}8{#/blank#} letting it through.”

    St. Peter opened the suitcase to inspect（检查）the things {#blank#}9{#/blank#} the man found too precious to leave behind and exclaimed (感叹), “You brought paving(铺路的) stones? As you can see, the great street of the city of heaven {#blank#}10{#/blank#} (make) of pure gold!”

    Last summer holiday, I took part in a teaching project and volunteered{#blank#}1{#/blank#}(teach) in a countryside primary school for two weeks.

    When we arrived at the school, though shocked by the poor living conditions, we quickly adapted {#blank#}2{#/blank#} to the life there. My good friend Tom and I were in charge of the third year students, {#blank#}3{#/blank#}(consist) of just 18 boys and girls. We not only taught them English and maths, but also organized some after-school {#blank#}4{#/blank#}(activity) for them. Gradually, I found that many of the students were actually quite 6{#blank#}5{#/blank#}(talent). But some had to leave school early, which is{#blank#}6{#/blank#}(large) because their families were under heavy financial pressure, and they had to find a job to support the family.

    As well as giving lessons, we also helped set up a reading room in the school {#blank#}7{#/blank#} students hardly had any access{#blank#}8{#/blank#} good reading materials except textbooks. With the help of school staff and students, we cleaned out an abandoned classroom. When we placed the books students and teachers in my high school {#blank#}9{#/blank#}(donate) onto the shelves, I found the students were more than excited and {#blank#}10{#/blank#}(dive) into reading there.

    Two weeks quickly passed and we had to leave. I did not know how much we had actually taught them, but for me I learned a great deal—cherish what I possess and study harder.

    Many teachers believe that hands－on experience is the {#blank#}1{#/blank#}(good) way to learn. A group of students in the United States are putting that belief to the test. They {#blank#}2{#/blank#} (success) designed and built a robot for discovering unexplored mines {#blank#}3{#/blank#} the bottom of the sea. Students made the robot {#blank#}4{#/blank#}(answer) a challenge from the U．S. Department of Defense.

    The students recently tested the underwater vehicle {#blank#}5{#/blank#}(call) PerseusⅡin a 95－meter－long tank of water at the Stevens Institute of Technology.

    The robot costs about $15,000 to build. The students use a video game control to direct {#blank#}6{#/blank#}(it) movements in the tank. What's more, devices known as Japters {#blank#}7{#/blank#} (able) the robot to go up, down and toward its target in the water. Video cameras on the robot send images back to a computer through a 13－meter－long cable. Perseus Ⅱ,{#blank#}8{#/blank#}the students worked up to 20 hours a week to design and build, also has {#blank#}9{#/blank#} set of lasers (激光), which are used to measure the size of an object.

    DeLorme supervised the project from {#blank#}10{#/blank#}(begin) to end. He says the specialized requirements of robots were demanding.

    Fake news has long been {#blank#}1{#/blank#} serious problem, and social media {#blank#}2{#/blank#} (blame) for allowing fake news stories to spread. US tech{#blank#}3{#/blank#} (company) Facebook and Google have been using {#blank#}4{#/blank#} (analyze) technology to fact-check stories and add labels {#blank#}5{#/blank#} dubious (可疑的) ones to warn their readers.

    But recently a survey {#blank#}6{#/blank#} (find) that as many as 60 percent of people in the US still think that not enough is being done{#blank#}7{#/blank#} (keep) internet users away from fake news. According to Eric Carvin, social media editor at the Associated Press, {#blank#}8{#/blank#}(fight) fake news is like “whack-a-mole (打地鼠游戏)”, she said, {#blank#}9{#/blank#} means that for now, we'll just have to rely on {#blank#}10{#/blank#} (we) common sense to decide what's real and what isn't.
