Water has no colour, no shape, no taste and no smell. Water is everywhere. It is in the ocean, in the sea, in the river and in the lake. Water is {#blank#}1{#/blank#}(use). We use water to cook rice. We use water to take showers. We use water to put out fires. We can swim {#blank#}2{#/blank#}the lake and the sea. People in China have {#blank#}3{#/blank#}Dragon Boat Race in the river.

    Water is {#blank#}4{#/blank#}(value). It brings us happiness. Nothing can live without it. {#blank#}5{#/blank#}some people waste water and pollute water every day. They keep {#blank#}6{#/blank#}(throw)rubbish into rivers and lakes. Many {#blank#}7{#/blank#}(factory)even put waste water into rivers. Let's do {#blank#}8{#/blank#}(we)best to save water {#blank#}9{#/blank#}keep the water clean. Don't forget {#blank#}10{#/blank#}(turn)off the tap after you wash hands. Don't throw rubbish into rivers and lakes.

    Every morning Tom {#blank#}1{#/blank#} (go) to work {#blank#}2{#/blank#} train. He has a long way to go. So he always buys {#blank#}3{#/blank#} piece of newspaper. It helps him {#blank#}4{#/blank#} (spend) time on the train. Tom likes sports news very much. One morning on the train he is reading something about a world football match. The match is very {#blank#}5{#/blank#} (interest). So he forgets {#blank#}6{#/blank#} (get) off the train at his station. He does not know it. When he finishes {#blank#}7{#/blank#} (read), he {#blank#}8{#/blank#} (see) outside. It is far {#blank#}9{#/blank#} his station. He gets off at the next station. He has to go back by train. Of course, he {#blank#}10{#/blank#} (be) late for work.

    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.
