    All over the world people enjoy sports. Sports help people {#blank#}1{#/blank#} (keep) healthy, happy and to live longer. People play different games in winter and summer. Summer is good for swimming. And in winter people often go skating. Some sports are very {#blank#}2{#/blank#} and people everywhere like them. For example, football is very popular. In China, most people, men andwomen, boys and girls, like to watch football games. They often talk about them. {#blank#}3{#/blank#} (run) and jumping began long, long ago. But basketball and volleyball are rather new. People began to play them not long ago. And people are playing new sports or games all the time. Water skiing is one of {#blank#}4{#/blank#} (new) sports. People from different {#blank#}5{#/blank#} (country) may not be able to understand each other, but after a game they often become friends.

    Have you ever seen a hitchhiker (搭便车的旅行者) {#blank#}1{#/blank#} (stand) by the side of a road? Now drivers in Canada might see an unusual hitchhiker: a hitchhiking robot.

    One of its {#blank#}2{#/blank#} (invent), David Harris Smith, has hitched across Canada three times. Smith and a friend, Frauke Zeller, have built Hitchbot because they wanted {#blank#}3{#/blank#} (see) if people would stop and give the robot a lift and talk to it. The robot {#blank#}4{#/blank#} (chat) about things it had learned, and about {#blank#}5{#/blank#} (it) trip. You might think it's a joke, but Smith and Zeller's experiment has a serious point: can robot and people get along?

    Hitchbot {#blank#}6{#/blank#} (begin) its journey in Nova Scotia in July. It has already completed one {#blank#}7{#/blank#} (three) its 6, 000-mile trip to Victoria. More than 57,000 people are following its journey closely on Facebook and Twitter, and travelers have posted lots of photos on the websites. Hitchbot {#blank#}8{#/blank#} (do) some shopping, eaten motor oil and had fun with travelers. Nobody {#blank#}9{#/blank#} (know) when it will finish its journey. It might be longer than expected, but Zeller and Smith want Hitchbot to get as {#blank#}10{#/blank#} (many) rides as it can. It hasn't been in a self-driving car yet, but anything is possible!
