This spring, our teacher suggested we should do a green project and plant some trees around the school. Everyone thought it was {#blank#}1{#/blank#} great idea, so we started looking online for the best trees to buy. But we soon found that {#blank#}2{#/blank#} (choose) trees was not that easy. Our teacher suggested that we should look for trees that grew {#blank#}3{#/blank#} (natural) in our part of the world. That way, the trees would be more suitable {#blank#}4{#/blank#} the wildlife here. We learnt that trees are the{#blank#}5{#/blank#} (happy) when they have room to grow, with plenty of space for their branches. The trees might get {#blank#}6{#/blank#}(damage) close to the school playgrounds, for example. So we tried to avoid areas where students were very active. Finally, we found a quiet corner close to the school garden – perfect! Later we all {#blank#}7{#/blank#} (take) turns to check the trees regularly and make sure they had no strange spots or marks on the {#blank#}8{#/blank#} (leaf). We all knew that we wouldn't be at the school anymore by the time the trees grew tall, and that was a bit sad. {#blank#}9{#/blank#} we'd planted the trees to benefit not only the environment, but also future students at the school. We knew they'd get as much pleasure from them as we had. And that {#blank#}10{#/blank#} (think) really cheered us up!
