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.

    If you pay a visit to Liu Hasheng's restaurant in Harbin, you will find 18 robots there. They are ready {#blank#}1{#/blank#} (serve) you and make sure that your dining experience is perfect.

When you have ordered your meals, the robots in the kitchen begin to do the cooking. If the food {#blank#}6{#/blank#} (make), a robot waiter will glide (滑行) out of the kitchen to serve you with the meal you've ordered. And as customers enjoy {#blank#}7{#/blank#} (they) delicious food, a robot sings {#blank#}8{#/blank#} (beauty) songs for them.

    You may ask, "Where did all these robots come from?" Liu said they were designed and made by the Harbin Haohai Robot Company. Liu said he invested (投资) 5 million yuan in the restaurant, with each robot costing 200,000 yuan to 300,000 yuan. And the whole robot team is managed by the workers in the computer room.

    After a busy day, all the robots will go for a "meal", which is electricity. After 5 hours, the robots can continue their work for a day. The restaurant now provides a menu {#blank#}9{#/blank#} more than 30 dishes, and the average (平均) cost for a dinner is about 40 yuan to 50 yuan. Do you want to go {#blank#}10{#/blank#} have a try in this restaurant?
