Make yourself know the type of  {#blank#}3{#/blank#}  you are standing on. Wet or uneven（不平坦的）ground can cause you to {#blank#}4{#/blank#}  down in a crowd of moving people.

 If you find {#blank#}5{#/blank#}   in the middle of a moving crowd, you must be careful. Do not walk {#blank#}6{#/blank#}  the moving direction and do not stop or sit down, because you could get trampled (踩踏)  {#blank#}7{#/blank#} Instead, move in the same {#blank#}8{#/blank#}  of the crowd. Keep your{#blank#}9{#/blank#}  up by your chest（胸部）to protect your chest. If you fall down, get up quickly, If you can't get  {#blank#}10{#/blank#}  , ask someone to pull you back up. If you have kids, lift  {#blank#}11{#/blank#}  up.

 If you fall and cannot get up, keep on  {#blank#}12{#/blank#}   in the same direction of the crowd. If that is not  {#blank#}13{#/blank#}   , then cover your head with your arms.

 Try to get away from hard things in a crowd. If you're pushed against them, {#blank#}14{#/blank#}   a result, you may be hurt badly.

 We should learn to {#blank#}15{#/blank#}  ourselves. Stay away from the crowd.

Remember: Whatever you do, safety is first!

   Life today has brought about new problem. One of the biggest problems of every nation is pollution. In America, there are laws {#blank#}1{#/blank#} the air and water clean.

   When food is brought from the store to the home, it is packed in paper, glass, or plastic. Every day a newspaper comes to the home.

The truck dumped the garbage into a large hole and then earth was pushed over the garbage until the hole was filled. Then, a new hole must be found.
As the years went by, the garbage increased as the population {#blank#}5{#/blank#} . Scientists suggested using some garbage again. They advised businessmen {#blank#}6{#/blank#} money by recycling or using paper, glass, and plastic again.
   Now, a recycling truck comes to each home once a week {#blank#}7{#/blank#}  up materials. American families are told {#blank#}8{#/blank#} their newspaper in boxes and clean all glass, and plastic. The truck takes them to factories for recycling.
   Recycling is a way {#blank#}9{#/blank#} the environment from pollution by {#blank#}10{#/blank#}  many materials again.

    When I was born, my doctor told my mother that there was something wrong with my l{#blank#}2{#/blank#}. They were too soft to be able to walk. A{#blank#}3{#/blank#}the news was bad, my mother didn't become frustrated(沮丧的). She didn't believe what the doctor said and started to look for other ways.

    My mother k{#blank#}4{#/blank#}looking for other doctors for me, and finally she succeeded. The doctor and his team in the hospital did everything t{#blank#}5{#/blank#}could to help me. They also asked my parents to teach me to do some e{#blank#}6{#/blank#}to help me walk. One day when my mother came to pick me up. I crawled(爬) towards her. She was so surprised and happy that she couldn't believe her eyes. Crawling was not walking, but it was a good s{#blank#}7{#/blank#} Day by day, I could walk by myself.

    When I grew up, my mother a{#blank#}8{#/blank#}told me these stories. She said that if I thought of what she said whenever I met difficulties, I could do a{#blank#}9{#/blank#} successfully. I have been working hard and I have turned out to be a very e{#blank#}10{#/blank#}person. I get best grades in school and I am a good dancer and swimmer. What the story tells us, as my mother always says, is: Never give up.
