When you take a walk in any of the cities in the West, you can see a lot of people {#blank#}1{#/blank#}(walk) with dogs. It is still true that a dog is the most useful and faithful animal in the world, but the reasons why people keep a dog {#blank#}2{#/blank#}(change). In the old days people used to train dogs to protect themselves against attacks by other beasts. And {#blank#}3{#/blank#}(late) they came {#blank#}4{#/blank#}(realize) that a dog was not only useful for protection,{#blank#}5{#/blank#} willing to obey his master. For example, when people used dogs for hunting, the dogs would not eat what was caught without {#blank#}6{#/blank#}(permit). But now people in the city need not protect themselves against attacks of animals. Why do they keep dogs, then? Some people keep dogs to protect themselves from robbery. But the {#blank#}7{#/blank#}(important) reason is for companionship. For a child, {#blank#}8{#/blank#} dog is his best friend when he has no friends to play with. For young couples, a dog is {#blank#}9{#/blank#}child when they have no children. For old couples, a dog is also their child when their real children have grown up. So the main reason why people keep dogs has changed from protection {#blank#}10{#/blank#} friendship.

    Nowadays, it is common{#blank#}1{#/blank#} more and more high school students open their own microblogs on the Internet. For one thing, it can provide a colorful platform to show their talent. For another, it is a useful way{#blank#}2{#/blank#} (release) their pressure. And all these make it more and more popular with high school students. But many parents and teachers hold a different view. They think that managing one's microblog will take a lot of time and energy，{#blank#}3{#/blank#} should be used to study.

    In my view, I am greatly in favor{#blank#}4{#/blank#} this activity. Today the Internet is playing {#blank#}5{#/blank#} important role in our life. Therefore, as high school students of the Information Age, we need to learn to make use of this{#blank#}6{#/blank#} (value) tool to communicate and display ourselves. What's more, opening and organizing microblogs need various abilities such as writing, designing, being skillful at computer and so on. Only if we master those abilities can we make a successful microblog. As a result, we improve ourselves while{#blank#}7{#/blank#} (organize) our micro blogs.

    In fact, the microblog {#blank#}8{#/blank#}(oneself) is of little harm. It is your attitude towards it that{#blank#}9{#/blank#} (matter). We should take the{#blank#}10{#/blank#}(advantage) and avoid some bad effects.

    I was traveling in a small place in New York. That place had no taxi for a short {#blank#}1{#/blank#} (distant). One had to take a rickshaw(人力车).

    I called out for an old man in the waiting line. Before I got on the rickshaw, I {#blank#}2{#/blank#} (automatic) asked how much he would charge to take me across to the Mall. I {#blank#}3{#/blank#} (tell) “10 dollars”. Then I started bargaining. He just gave a hard smile and said, “Whatever you feel like, please give me. It is not necessary{#blank#}4{#/blank#}(bargain) on this small amount.”

    I was a bit ashamed at myself and kept quiet while he continued, “{#blank#}5{#/blank#}(like) those taxis, my vehicle does not run on petrol or diesel(柴油) or even gas;{#blank#}6{#/blank#} runs on my sweat. So please give it to me {#blank#}7{#/blank#} a smile, for the money has to feed so many {#blank#}8{#/blank#}(hunger) mouths at home.”

    When we reached the Mall, I gave him the money and the smile{#blank#}9{#/blank#} requested and added a gentle pat on his back. He smiled back as if to give me a receipt and I would preserve his smile for {#blank#}10{#/blank#} long time.

    The solar system was{#blank#}1{#/blank#}(die) out. People all around the world built giant planet thruster to move Earth to a new star system. Yet the 2005 years journey came with unexpected dangers. In order to save human beings, a group of young people in this age of a wandering earth came out{#blank#}2{#/blank#}(brave) and fought hard for everyone's{#blank#}3{#/blank#}(survive). It is{#blank#}4{#/blank#}adaptation of Cixin Liu's The wandering earth.

    Cixin Liu is a writer{#blank#}5{#/blank#}led a revolution in science fiction, becoming the first Chinese{#blank#}6{#/blank#}(award)the Hugo Award in 2015. Like Hollywood space movies where Americans are pictured as the only ones capable{#blank#}7{#/blank#}saving human being, here Chinese astronauts are the adventurers among the global space community{#blank#}8{#/blank#}(determine) to complete the task.

    Regardless of the outcome for the history of mankind, Chinese astronauts have decided to choose hope. Hope is as precious{#blank#}9{#/blank#}diamond, which is the only way home. As the saying goes in the movie, among tens of thousands of matters, safety is the first one.{#blank#}10{#/blank#} (regular)operations will make your loved ones shed tears.
