    Hello everyone! I'm Lucy. My parents love travelling with me. We have been in Australia{#blank#}1{#/blank#} three days. We're having a {#blank#}2{#/blank#} time here. Australia is {#blank#}3{#/blank#} sixth largest country in the world. There is too much to see. And it is impossible for me to tell you {#blank#}4{#/blank#}. Sydney is a beautiful city. There are both many trees {#blank#}5{#/blank#}beautiful flowers around the houses and they look really beautiful. There are also some special {#blank#}6{#/blank#} in Australia, such as kangaroos and koalas. They are really lovely.

    During the past three days, we've visited many {#blank#}7{#/blank#} of interest around Sydney. I'd like to spend more time here, but we will fly to {#blank#}8{#/blank#}city, Cairns, to see coral reefs(珊瑚礁) tomorrow. People say that words cannot tell the beauty of the colorful coral. Many famous cartoon films were made there. Now we are busy packing our bags. We will enjoy{#blank#}9{#/blank#} in Cairns this time tomorrow. I'm looking {#blank#}10{#/blank#} to going there!

    People have always been interested in animal communication and scientists have done a lot of research {#blank#}1{#/blank#} this subject. Most animals communicate by smell. Dogs are famous for this. When a dog walks outside, it learns about other dogs by {#blank#}2{#/blank#} (smell) things. Dogs {#blank#}3{#/blank#} (help) the police since a long time ago. Everyone has heard birds singing. Research has shown that many other animals use sounds {#blank#}4{#/blank#} (communicate). Frogs and insects communicate with sounds. Usually the "men" make sounds to invite the "{#blank#}5{#/blank#} (woman)". Whales and elephants {#blank#}6{#/blank#} use sounds to communicate. These sounds can travel very far through water or the ground. However, it is {#blank#}7{#/blank#} (possible) for humans to hear some of the sounds. They are {#blank#}8{#/blank#} too low or too high for us. Animals have always used body language to communicate as well. {#blank#}9{#/blank#} a dog puts its tail under its body, it is scared. When a dog wags its tail and {#blank#}10{#/blank#} (open) its mouth, it is happy.
