David is a student in a university. He didn't use to go sightseeing. However, last week he went on holiday in Yunnan. His cousin Cindy lived in Kunming. Both of them {#blank#}1{#/blank#} (have) a good time.

    First, he went to Kunming by plane. When he arrived there, Cindy took him to many places{#blank#}2{#/blank#} (visit). David liked the weather there. It was not cold {#blank#}3{#/blank#} hot. It was {#blank#}4{#/blank#} (real) fine. He also liked all kinds of flowers there. After two weeks, David and Cindy went to Dali by train. They visited the old famous city Dali and some other {#blank#}5{#/blank#} (place) of interest there. David learnt {#blank#}6{#/blank#} many local customs as well.

    One week later, David and Cindy took the bus to Lijiang— {#blank#}7{#/blank#} beautiful town. They visited Jade Dragon Snow Mountain. It was really wonderful. They also visited the old town of Lijiang. There were many {#blank#}8{#/blank#} (interest) stores and restaurants there. They ate much fine food there.

    David spent almost all his pocket money {#blank#}9{#/blank#} (buy) presents for his classmates. David had to come back to the university, so they only stayed in Lijiang for one week.

    David really enjoyed {#blank#}10{#/blank#} (be) there. He hopes to visit it this winter holiday again.

    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!
