Nowadays, mobile phones are more and more popular, especially {#blank#}1{#/blank#} teenagers. Those people {#blank#}2{#/blank#} like to play with mobile phones all day {#blank#}3{#/blank#} (call) phubbers. One of the {#blank#}4{#/blank#} (reason) is that it is fun for them {#blank#}5{#/blank#} (spend) time playing with new kinds of mobile phone software, such as {#blank#}6{#/blank#} (chat) on Wechat. I think spending too much on mobile phones is bad for everyone. For a student, it will not only get in the way of study but also influence our health. My cousin was so {#blank#}7{#/blank#} (interest) in mobile phone games {#blank#}8{#/blank#} he lost his interests in any other subject. And he didn't enter the best high school in the town {#blank#}9{#/blank#} he did well enough in school when he {#blank#}10{#/blank#} (study) in primary school.

In my opinion, it's time to stop using mobile phones while we are studying, working, driving or walking. It's too dangerous to do that. Let's call on more young people: Don't be phubbers!

    Martin is a manager. His computer and phone {#blank#}1{#/blank#}(be) important for him. In the office, he {#blank#}2{#/blank#} (work) on the computer. When he isn't in, he can work on {#blank#}3{#/blank#}(he) phone. How can he do that? The phone can work like {#blank#}4{#/blank#} (冠词) computer. That's really good {#blank#}5{#/blank#} (介词) his work.

    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!
