Once a group of 50 people was attending a seminar. Halfway{#blank#}1{#/blank#} his talk, the speaker stopped and decided{#blank#}2{#/blank#}(create) a group activity. He went around the hall and gave each person a balloon. Each one was asked to write his or her name on the balloon{#blank#}3{#/blank#}(use) a marker pen. Then all the balloons{#blank#}4{#/blank#}(collect) and put in another room.

    The speaker then led the group to the room full of balloons and asked them to find the balloon that had their name{#blank#}5{#/blank#}(write) on within five minutes.  Everyone was{#blank#}6{#/blank#}(hurry) searching for their name, bumping into each other, pushing each other around. It was chaos. At the end of the five minutes no one could find their own balloon.

    Now each person was asked to randomly collect{#blank#}7{#/blank#}balloon and give it to the person whose name was on it. Within two minutes everyone had their own balloon. When everyone quieted down, the speaker began to talk, saying that this is exactly{#blank#}8{#/blank#}was happening in our lives.

    We may like to think of{#blank#}9{#/blank#}(us) more important than others, but our happiness sometimes lies in the happiness of other people. Give them their happiness {#blank#}10{#/blank#}you will get your own happiness.

Online shopping is coming into fashion in most cities, where people are able to make full use of the rapidly—developed internet technology. Nowadays, can we find a person {#blank#}1{#/blank#} has not experienced online shopping? Definitely not.

    Online shopping {#blank#}2{#/blank#}(welcome)by most people due to various reasons. From the perspective of consumers, it can save some time for people who don't have much spare time. Just click the mouse, they can get {#blank#}3{#/blank#}they want while staying at home. For the retailers(零售商), it can cut some costs for those who don't have much circulating funds. Compared with the traditional trade mode, they don't have to spend money {#blank#}4{#/blank#}(rent) a house. {#blank#}5{#/blank#}, there are still some disadvantages in online shopping. First, a face-to-face deal makes online shopping less reliable and {#blank#}6{#/blank#}(believe). Second, people will lose {#blank#}7{#/blank#}fun of bargaining（讨价还价）.

    {#blank#}8{#/blank#}is clear that shopping on the internet has become a popular trend in modern society. It's {#blank#}9{#/blank#}great importance that we need to make the relative laws in accordance with(与…一致) the rapid growth of online shopping. Only in this way can we enjoy the pleasure and {#blank#}10{#/blank#}(convenient)of online shopping without the concern of being cheated.

    Throughout modern history, perhaps there has never been a scientist as iconic (偶像的) as Stephen Hawking.

    Whether he{#blank#}1{#/blank#}(educate) the world with his knowledge of the universe, or making fun of himself in TV shows, it is hard to imagine what the world will be like now Hawking is no longer in.

    On March 14, 2018, the British physicist passed away in Cambridge. Since then, many people have expressed their condolences (哀悼) on social media, including British computer scientist Tim Berners-Lee{#blank#}2{#/blank#}invented the World Wide Web. “We have lost a great mind and a wonderful spirit,” Berners-Lee wrote.

    Hawking was an icon for many reasons, but he will be best remembered {#blank#}3{#/blank#} his work in the field of science.

    Building on German scientist Albert Einstein's work, Hawking explained his belief that space{#blank#}4{#/blank#} (start) with the Big Bang, and will end with black holes.

“This complete set of laws can give us the {#blank#}5{#/blank#} (answer) to questions like 'How did the universe begin?'” Hawking wrote in his 2010 work The Grand Design. “Where is it going and will it have an end? If so, how will it end?”

    Besides his work in science, he also managed to overcome many difficulties in his personal life. While{#blank#}6{#/blank#} (study) at Cambridge University, he was diagnosed with motor neuron (运动神经元) disease at the age of 21. His {#blank#}7{#/blank#} (ill) left him paralyzed and he was told he only had a short time to live. However, he went on to become one of the{#blank#}8{#/blank#} (great) minds the world has ever known.

    “I felt it was unfair. Why should this happen to me?” he once recalled. “At the time, I thought my life was over and that I would never realize the potential I felt I had. But now, 50 years later, I can be satisfied with my life.”

Hawking left behind a great legacy (遗产). His signature book A Brief History of Time: From the Big Bang to Black Holes{#blank#}9{#/blank#}(publish) in 1988, became one of the world's best-selling science publications. And in 2014, UK actor Eddie Redmayne played Hawking in the movie The Theory of Everything, which tells the tale of the physicist's life.

    He may no longer be with us{#blank#}10{#/blank#} Hawking will continue to inspire the world for generations to come. As he once said himself, “Look up at the stars and not down at your feet!”

    Choice of seating in the lecture hall can affect a college student's performance, a study suggests.

    Lectures are a main part of higher education, and {#blank#}1{#/blank#}(understand) how students interact and learn within the lecture theatre environment is central to successful learning. Researchers from Sheffield Hallam University in the UK examined {#blank#}2{#/blank#} (student) reasons for choosing particular seats in a lecture hall, and investigated how seating positions are related {#blank#}3{#/blank#} students' performance.

    "Interaction is a key part of learning and knowing who the students are interacting with can be {#blank#}4{#/blank#} great benefit when designing activities," said David P Smith of Sheffield Hallam University.

    Many students {#blank#}5{#/blank#} (prefer) being able to sit with their friends, {#blank#}6{#/blank#} others were more concerned with either attracting or avoiding the lecturer's attention. Some students chose seats {#blank#}7{#/blank#} allowed them to see and hear clearly. But others {#blank#}8{#/blank#} (easy) picked seats that made them feel less depressed, they said.

    Friendship groups who sat together tended {#blank#}9{#/blank#} (achieve) similar grades, and students who sat alone at the edges were likely to do worse than average.

    Lecturers may be able to use these findings to offer assistance to {#blank#}10{#/blank#} (anxiety) students，and to support the learning of all students by encouraging interactions between the different groups.
