Come and meet my best friend, Lisa. Lisa is a beautiful girl. Many people like her because {#blank#}1{#/blank#} her good look. So do I. As my best friend, she likes to do {#blank#}2{#/blank#} same things as me. We {#blank#}3{#/blank#} like singing and reading books. There are also some {#blank#}4{#/blank#} (different) between us. I am shy and I always like to stay by myself. Lisa is much {#blank#}5{#/blank#} outgoing than me. She is {#blank#}6{#/blank#} (talent) in telling jokes. She often makes me {#blank#}7{#/blank#} (laugh). She is good at sports, too. She plays sports every day to keep healthy. She thinks it is not necessary for friends {#blank#}8{#/blank#} (be) the same. Her favorite {#blank#}9{#/blank#} (say) is, "A true friend reaches for your hand and {#blank#}10{#/blank#} (touch) your heart." What do you think of my best friend?

    From deserts and beaches to playgrounds, sand is a common sight. But you might not know that sand is also a useful resource. Sand is the second most-used resource in the world after water, the BBC reported. However, the UN said that sand is not limitless and that we might be running out of {#blank#}1{#/blank#}.

    Sand is made up of very small {#blank#}2{#/blank#} (piece) of rock, soil and minerals(矿物质). It can take tens of thousands of years to form. But now we are using sand more{#blank#}3{#/blank#} (quick) than it is being formed. According to the BBC, we use about 15 billion tons of sand every year {#blank#}4{#/blank#} build houses, roads and other things. People also put sand in the{#blank#}5{#/blank#} [si:] to make new islands. For example, the Palm islands are made up of three{#blank#}6{#/blank#} [lɑːdʒ] man-made islands in Dubai, United Arab Emirates. In 2010, they {#blank#}7{#/blank#} (take) 94 million cubic meters of sand to build. If people keep{#blank#}8{#/blank#}(use) this much sand, it will run out in many places. For example, Vietnam may run out of construction sand by 2020, Live Science noted.

    {#blank#}9{#/blank#} [sins] people need so much sand, they are trying to mine(开采) more of it. But this is bad for the environment. Mining sand may {#blank#}10{#/blank#} beaches to disappear and more floods to happen in places close to the sea. Also, this may affect the habitats (栖息地) of many plants and animals.

    On my recent tip to Sydney with my parents, we visited the Wildlife Park.

    The Wildlife Park has lots {#blank#}1{#/blank#}different birds. Some are local birds in Australia and they can only be found there. There {#blank#}2{#/blank#}(be) over 600 animals there, including kangaroos, koalas and crocodiles. They {#blank#}3{#/blank#}(keep )in the natural environment.

    We first spent some time with the kangaroos. We were allowed {#blank#}4{#/blank#}(touch)and feed them. It was exciting for me to get so close to {#blank#}5{#/blank#}(they).Also the koalas looked very lovely. I knew I couldn't carry them, so I took a photo with one. It was one of {#blank#}6{#/blank#}(wonderful)photos of my holiday in Sydney

    The Wildlife Park has plenty of freshwater {#blank#}7{#/blank#}saltwater crocodiles. Some of them are really big with huge{#blank#}8{#/blank#}(tooth)! I was so scared of them. There was also a bird show. The keepers showed us different species they had. I saw {#blank#}9{#/blank#}old parrot which could talk

    It made a great {#blank#}10{#/blank#}(impress)on me.

    I enjoyed the trip very much.
