春天，树上长出了一片片新叶;夏天，枝头茂密的树叶可以为我们提供清凉的树荫;秋天，树叶开始一片接着一片从枝头飘落……树叶的生命，就是这样在四季中循环往复。树叶说，能够为大树提供养分，让它长得那么壮实，真为自己感到自豪！就让我们一起到绘本中去了解一片树叶的一生吧！
　　I’m a leaf.
　　I live on a maple tree.
　　See the ladybug？
　　She’s crawling on me.
　　It tickles！
　　Many leaves live on my tree.
　　We have a summer job.
　　We make tree food.
　　We make it from air and sunlight.
　　That sun feels good.
　　We also need water to make tree food.
　　Rainwater goes into the soil.
　　It goes into the tree’s roots.
　　It goes up the tree.
　　It flows into my veins（叶脉）.
　　My veins are like little pipes.
　　I mix sunlight， air， and water.
　　Then I add something green.
　　It’s called chlorophyll（叶绿素）.
　　Chlorophyll is green.
　　It makes me green.
　　All summer long，
　　I have made tree food.
　　Once a caterpillar came by.
　　Nibble， nibble， nibble.
　　It ate a little hole in me.
　　But I still did my job.
　　Once a spider came by.
　　Busy， busy， busy.
　　It made a big web.
　　But I still did my job.
　　Once a squirrel jumped on me.
　　Boing， boing， boing！
　　It ran right over me！
　　But I still did my job.
　　Now fall has come.
　　My work is over.
　　My green goes away.
　　Now I am ...
　　Red！ Yellow！ Orange！
　　It’s party time！
　　All the leaves on my
　　tree are turning colors！
　　People ooh and aah.
　　The wind blows.
　　We break away.
　　We dance with the wind.
　　Gently， we land on the ground.
　　We rest.
　　Winter has come.
　　The forest is white with snow.
　　Some trees stay green.
　　They are called evergreens（常青樹）.
　　Slowly， leaves turn into soil.
　　The soil holds roots.
　　The soil holds water.
　　The soil holds animals sleeping in dens.
　　Winter is over.
　　The soil warms.
　　Hi！ I’m a baby leaf.
　　Spring is here.
　　I’m the first bud to sprout on my tree.
