Animals are helpful. And animals are {#blank#}1{#/blank#} very important part of the world. October 4 is World Animal Day. This is a great chance to celebrate our lovely {#blank#}2{#/blank#} (friend).

    They help keep nature on the right track. For example, bees move pollen (花粉) and seeds among plants. If they don't do so, things may stop {#blank#}3{#/blank#} (grow), and we would have no food {#blank#}4{#/blank#} eat.

    Animals can also tell {#blank#}5{#/blank#} (we) about our past. Studies on monkeys show us human evolution (进化).

    We also keep animals {#blank#}6{#/blank#} pets. They give us support (支持) and make us happy. So we {#blank#}7{#/blank#} (not) get lonely.

    We need animals in our {#blank#}8{#/blank#} (life), and we can't live {#blank#}9{#/blank#} (with) them. So always show respect (尊敬) and love {#blank#}10{#/blank#} (to) them.
