We can't stop an earthquake，but we can do things to make sure they don't destroy (毁坏) whole cities. First，it is not a {#blank#}1{#/blank#}idea to build houses along lines where {#blank#}2{#/blank#}of the earth's plates (板块) join together. Second，if you think there {#blank#}3{#/blank#}be an earthquake，it is better to build houses on rocks， not on {#blank#}4{#/blank#}Third， you must make the houses as {#blank#}5{#/blank#}as possible. Weak buildings will {#blank#}6{#/blank#}down in an earthquake，but strong ones may stay up.

    Scientists are {#blank#}7{#/blank#}that one day an even bigger earthquake will hit the part around San Francisco. They call it “The Big One”. However，people today are still building more {#blank#}8{#/blank#}The population in and around San Francisco is {#blank#}9{#/blank#}ten times more than it was in 1906. This means that {#blank#}10{#/blank#}there is another earthquake，a great many houses and buildings will be destroyed.

    As you may know, coral (珊瑚) Is not a plant, but an animal. However, coral reefs (珊瑚礁) around the world are in {#blank#}1{#/blank#}. Here is a piece of bad news. Thailand will close one of its beaches to protect its coral {#blank#}2{#/blank#} business activities for tourists. The beach is so famous that {#blank#}3{#/blank#} of tourists put it on their wish lists. More than 5, 000 visitors visit it a day. They arrive by boat. This does {#blank#}4{#/blank#} harm to the coral reefs. Most of the coral has died. The beach will be closed between June and September to let the coral come {#blank#}5{#/blank#} to life.

    Experts (专家) say that 80% of Thailand's coral reefs have been {#blank#}6{#/blank#}. Too many tourists {#blank#}7{#/blank#} a lot of pollution to these beaches. An expert said the biggest problems were hotels by the beaches, boats, and plastic waste in the sea. He believed the {#blank#}8{#/blank#} choice was to close the beaches forever. He said, "I hope the {#blank#}9{#/blank#} can take steps to protect the coral reefs. At the same time, I also hope all of us should {#blank#}10{#/blank#} our best to protect the environment around us."

    No leaves are exactly the {#blank#}1{#/blank#} in the world. Nobody in the world is the same {#blank#}2{#/blank#} you. You are unique (独一无二的). Everybody is different {#blank#}3{#/blank#} others. That is good, because it makes the world an {#blank#}4{#/blank#} place. Some people are {#blank#}5{#/blank#} than you, but others are shorter than you. {#blank#}6{#/blank#} your hair is the same color as your friend's but it may be longer than{#blank#}7{#/blank#}. I am sure you have some friends who are smarter than you. And you also have some friends around you who are not {#blank#}8{#/blank#} at some things. What does your best friend like to do? Do you both like {#blank#}9{#/blank#} the same clothes every day? I think in some ways you are the same, but in many other ways you are different. So say {#blank#}10{#/blank#} to the world, "I am unique!"
