Deep under the sea

    Imagine a trip to the deep ocean. What would you {#blank#}1{#/blank#} (期待) to see? Would it be possible that you find {#blank#}2{#/blank#}(奇怪的) new animals and plants?

    As we know, sunlight warms the surface {#blank#}3{#/blank#} (部分) of the ocean. Plants and animals which need sunlight and warm water live there. But deep in the ocean, other animals live in water that is cold and {#blank#}4{#/blank#}(黑暗的).

    The deep ocean is freezing cold. The water pressure of very deep water can {#blank#}5{#/blank#} (伤害) you. So what animals live in the ocean? Where do they live? How many are there? Scientists have studied and counted animals for ten years to find out. The {#blank#}6{#/blank#} (报告) is surprising.

    The first surprise is where things live: everywhere! They live in the hottest and coldest places. Some live in deed places {#blank#}7{#/blank#} (没有) light or air.

    The second surprise is that there are over 230,000 {#blank#}8{#/blank#} (种类) of animals and plants under the sea. Over six {#blank#}9{#/blank#} (千) have never been seen before.

    So what {#blank#}10{#/blank#} (别的) is living in the deep ocean? Will there be surprises to come?

    What should you do if you are in a crowd(人群)？ The first and most important thing is to make yourself c{#blank#}1{#/blank#}to know where you are and where the exits are. No matter where you are, make sure you a{#blank#}2{#/blank#}know how to get out and to be safe.

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

    If you find yourself in the middle of a moving crowd, must be careful. Do not walk a{#blank#}4{#/blank#}the moving direction and do not stop or sit down b{#blank#}5{#/blank#}you could get trampled (踩踏)easily. I{#blank#}6{#/blank#}, move in the same direction of the crowd. Keep your hands up by your chest(胸部)to protect your chest. If you fall down, get up quickly. If you can't get up, ask someone to pull you back up. If you have kids, I{#blank#}7{#/blank#}them up.

    If you fall and cannot get up, keep on moving in the same direction of the crowd. If that is not possible, then cover your head with b{#blank#}8{#/blank#}arms. Try to get away from hard(硬的)things in a crowd. If you're pushed towards them, as a r{#blank#}9{#/blank#}, you may be hurt badly.

    Remember: Whatever you do, s{#blank#}10{#/blank#}is first! We should learn to protect ourselves, Stay away from the crowd.
