Hello, I'm Mike. I'm from America. I'm a middle school s{#blank#}1{#/blank#} like you. I have a computer. I use it every day. Because we do our homework on our c{#blank#}2{#/blank#} Do you know how we write our homework on the computer? It's very easy. F{#blank#}3{#/blank#} use the mouse, c{#blank#}4{#/blank#} new document" and o{#blank#}5{#/blank#} a new document. N{#blank#}6{#/blank#} , you write your homework in the new document. U{#blank#}7{#/blank#} the keyboard, you click "s{#blank#}8{#/blank#} " and write a name for it in the box. T{#blank#}9{#/blank#} click "save" again. F{#blank#}10{#/blank#} , click "print" and "OK".

    When a person is h{#blank#}1{#/blank#} or suddenly becomes ill, people give him immediate care. We call it first aid. When there is a sudden s{#blank#}2{#/blank#}, time is very important, so first aid plays a very important role. Immediate action is necessary when someone loses lots of b{#blank#}3{#/blank#} or when b{#blank#}4{#/blank#} stops for a short time.

    Everyone should know something about how to care for a person with a sudden illness. Even a small injury(损伤)can be very dangerous. And it may result in(导致) d{#blank#}5{#/blank#}, so everyone should know something about first aid.

    When first aiders face a sudden situation, they must be able to keep calm and organize other people to help. He or she must know how to c{#blank#}6{#/blank#} blood and take care of injuries. Knowing how to move the injured without causing more injuries is also very i{#blank#}7{#/blank#} .

    In our country, hundreds of people die in traffic a{#blank#}8{#/blank#} every year because most people don't have first aid knowledge. If more people know about first aid, more lives could be saved. We may face a sudden situation anywhere. One day somebody from our family may get hurt or suddenly become ill. If we don't know anything about first aid, they may get into t{#blank#}9{#/blank#}. But if we know something about it, we o{#blank#}10{#/blank#} can do something for them right away.
