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.
