The police do many things for us. They help keep our things and us safe and help keep cars {#blank#}1{#/blank#}（move） safely. They take care of people who are {#blank#}2{#/blank#} (hurt). Then they send these people {#blank#}3{#/blank#} a doctor.

    The police go around town to see {#blank#}4{#/blank#} everything is all right. They get around town in many ways. Some of them walk or go by car. In some big cities, some of the police ride on {#blank#}5{#/blank#}(horse). It is strange.

    As {#blank#}6{#/blank#} (them) go around town, the police help people. Sometimes they find lost children and take them home. If the police see a fight，they will put {#blank#}7{#/blank#}(冠词) end to it right away. Sometimes people will ask the police how to get to a place in town. The police can always tell the people which way to go.

    Some police stand at crossings. They tell the cars when to go and when to stop. They help children {#blank#}8{#/blank#} (cross ) the street. They also help people who can't walk too {#blank#}9{#/blank#} (well).

    Without the police, our streets would not be safe. Cars might go too fast and hurt people. {#blank#}10{#/blank#}(lose) people might never be found. The police do a good job. We need them. And we should thank them for a job well done.

    "Dreams (梦 ) may be more important than sleep. We all need to dream，" some scientists say.

    Dreams take up about one quarter of our {#blank#}1{#/blank#}(sleep) time. People have several dreams each night. Dreams are {#blank#}2{#/blank#} short films. They are usually in color. Some dreams are like old films. They come to us over {#blank#}3{#/blank#} over again. That may be because the dreamer is {#blank#}4{#/blank#}(worry) about something. Dreaming may be a way of trying to find an answer.

    Some people get new ideas about their work {#blank#}5{#/blank#} dreams. They may have been thinking about their work all day. These {#blank#}6{#/blank#}(think) can carry over into dreams.

    Sometimes, we wake up with a good {#blank#}7{#/blank#}(feel) from a dream. But often we can't remember the dream. Dreams can disappear (消失) {#blank#}8{#/blank#}(quick) from memory (记忆).

    Too much dreaming can be harmful (有害的). The {#blank#}9{#/blank#}(much) we sleep， the longer we dream. The mind is hard at work when we dream. That is {#blank#}10{#/blank#} we may have a long sleep and still wake up tired.

    Yash Gupta has worn glasses for many years. When they broke one day and he was not able {#blank#}1{#/blank#} (wear) them to school, he had a big problem. He could not see much of what was going on in his classroom. {#blank#}2{#/blank#} he learnt nothing at the end of the day.

    Yash quickly got his glasses fixed, but this experience changed {#blank#}3{#/blank#} (he) life. He thought probably many kids around the world did not have proper (合适的) glasses {#blank#}4{#/blank#} (help) them learn at school.

    So, he {#blank#}5{#/blank#} (make) some researches. He found that 13 million children around the world didn't have proper glasses. And he learnt that not having glasses could cause a 20％ loss in learning!

    Instead of {#blank#}6{#/blank#} (shake) his head at this problem. Yash decided to do something. A few months later, he started {#blank#}7{#/blank#} small organization, Sight Learning, to help find glasses for other kids that need them. He started Sight Learning in 2011 and since then he has helped {#blank#}8{#/blank#} (thousand) of young students around the world! Sight Learning provides {#blank#}9{#/blank#} (glass) for students who need them but cannot afford them.

    Yash is a great example of a young person who takes action to improve not only his own life, but also those {#blank#}10{#/blank#} others.
