China has the largest population in the world. The large population has caused many {#blank#}1{#/blank#} /′səʊʃl/ problems for the whole nation. For example, there is {#blank#}2{#/blank#} (little) living space for each family. And it is not easy {#blank#}3{#/blank#} find jobs. It's also hard for China to {#blank#}4{#/blank#}/sə′plaɪ/ energy and water to satisfy people's daily needs. Most cities are more crowded {#blank#}5{#/blank#} before, and the traffic is much heavier. {#blank#}6{#/blank#} (nature) environments are becoming {#blank#}7{#/blank#}/wɜ:s/. China has taken many measures to control the population. And the measures have worked well in it. {#blank#}8{#/blank#}, our government still faces a serious population problem. So we have a long way to go.

    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.
