    Animals are people's friends. But many wild animals are facing the {#blank#}1{#/blank#} (危险) of dying out, because the environment that they are living has {#blank#}2{#/blank#} (变化) greatly. Their living area has become {#blank#}3{#/blank#} (小) than before because of {#blank#}4{#/blank#} (污染) and the {#blank#}5{#/blank#} (发展) of cities. They have no room to live in {#blank#}6{#/blank#} (除了) the zoo. And many of the wild animals now can't find enough food to eat. At the same time, man is killing animals for their fur and meat. Now the situation is serious. So we should do something to {#blank#}7{#/blank#} (保护) the animals. For example, we should set up some nature reserves so that animals can live {#blank#}8{#/blank#} (自由) and stop people from {#blank#}9{#/blank#} (杀死) animals. Of course a {#blank#}10{#/blank#} （健康的） environment which has fresh air, clean water and green grass is also important for animals. Only in this way can we save them.
