It's summer holidays. For Jacob, it means having a lot of free time to play with  {#blank#}1{#/blank#} (he) friends. Usually, he isn't so excited about it, {#blank#}2{#/blank#} (连词) this summer is different. This summer, he is going to see Justin Timberlake — one of his favourite singers

    Jacob got four tickets to Justin Timberlake's concert after he {#blank#}3{#/blank#}（win) an online singing completion （比赛） {#blank#}4{#/blank#}. (see) Justin Timberlake is one of his dreams (梦想), so it will something he will never forget.

    The biggest problem he had was  trying {#blank#}5{#/blank#}(choose) just three friends to go with him. He {#blank#}6{#/blank#} (wish) that all his friends could go. He asked his mother {#blank#}7{#/blank#}(介词) help. She told him to choose people who also liked Justin Timberlake. Jacob thought it was {#blank#}8{#/blank#} (冠词) good idea, so he chose three friends who liked Justin Timberlake as much as he did. He felt sorry for not{#blank#}9{#/blank#}(take) his best friend Andrew, but he knew that Andrew didn't like Justin Timberlake' s music that much. Jacob's three friends were all very excited when he {#blank#}10{#/blank#} (tell) them the good news.

    Now the concert is just a week away and Jacob can't wait any longer.

    What will the world be like in the future? I think a lot of what we see in science fiction films (科幻电影){#blank#}1{#/blank#}(come) true.

    There {#blank#}2{#/blank#} (be) flying cars parking (停) on top of buildings. If this happens, there won't be any busy streets! I {#blank#}3{#/blank#} (think) that most houses will be green, because we {#blank#}4{#/blank#} (use) green energy (能源) like wind. In the future, I think robots{#blank#}5{#/blank#} (do) most housework, so life will be easier.There {#blank#}6{#/blank#}（be） robot teachers, too. Children{#blank#}7{#/blank#} (take) small computers to school, not books. No one really{#blank#}8{#/blank#}(know) what our future will be like. All we need to do {#blank#}9{#/blank#} (be) to believe in ourselves. As Albert Einstein once {#blank#}10{#/blank#} (say), "I never think of the future. It comes soon enough. "
