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!

    Plenty of people dream of going to Mars(火星).{#blank#}1{#/blank#}different from those people, 13-year-old Alyssa Carson has been working{#blank#}2{#/blank#}(happy)for that dream since the age of 4, according to a new report which{#blank#}3{#/blank#}(make)by the BBC not long ago.

    Alyssa tells the BBC, "I hope{#blank#}4{#/blank#}(go)to Mars because it is a place that no one has been to before. I want to take that first step." According to the BBC, she{#blank#}5{#/blank#}(attend) the USA's three world space camps so far.

    Her father, Bert Carson, tells the BBC that Alyssa plans to be on the first long journey to Mars, which is expected to take place in{#blank#}6{#/blank#}year of 2033."We are proud{#blank#}7{#/blank#} her, "he says." We have the next eighteen{#blank#}8{#/blank#}(year) planned out." One of those plans is Alyssa attending the International Space University.

    Of course, Alyssa's dream could come with{#blank#}9{#/blank#}(big)sacrifices(牺牲)than others. If Alyssa goes to Mars, maybe{#blank#}10{#/blank#}is very difficult for her to return to the Earth. Still, her father says, "If that's the only choice she has, she still wants to go." Alyssa agrees.
