Every year in Australia there are crocodile (鳄鱼) attacks (攻击) on humans. Two years ago, a 24-year-old German tourist died when she went {#blank#}1{#/blank#} in a lake. Although there were signs warning people that there might be crocodiles, the girl and {#blank#}2{#/blank#} friends decided to have a midnight swim. The girl {#blank#}3{#/blank#} disappeared and the next morning her body was found. Near it was a four-meter crocodile. And only last month two{#blank#}4{#/blank#} boys watched in fear as their friend was killed by a crocodile. They were washing their mountain bikes in a river at that time. Then, those two boys climbed a tree and stayed there for 22 {#blank#}5{#/blank#}while the crocodile waited below.

    Good morning, everyone. Standing here, I know it's time to say goodbye. When I look back to the past three years, many beautiful {#blank#}1{#/blank#} rush to my mind. When I walk by classrooms, it seems that the lessons will never stop. I can't forget the sunshine coming in {#blank#}2{#/blank#} the windows. I can't forget the library where I used to go. I can't forget tidy uniforms and lovely smiles. I'll remember the important people {#blank#}3{#/blank#} helped and supported me-my teachers and my friends. These moments are so unforgettable that I feel like {#blank#}4{#/blank#} them with you.

    Although we have to go our {#blank#}5{#/blank#}ways now, I hope we can value the happy time we spent together. My dear school, I love you, {#blank#}6{#/blank#}. And I really don't want to say goodbye.
