In 1996,39 American students started a very interesting project-the Green Tree Project. The students began the project by gathering walnuts in the fall. The nuts were buried in the cages in the school garden in Mid-November. In this way, the seeds could be kept cool and wet for several months be fore they started growing. In February, the seeds were dug up, so they could begin to sprout. Sprouted seeds were kept in refrigerators, so they could be stopped from growing until the time to plant. This helped keep the trees about the same size at planting time. In March, sprouted seeds were planted in paper soft drink cups. Each student was asked to plant twelve trees. Then the trees were carefully watered and watched. The first walnut trees began to appear in about a week. The students found this part of the project very exciting. On April 29th, the trees were transplanted to the lake. It took them only 90 minutes to plant all the trees. It was so interesting to see a treeless area turn into a forest fight before eyes!

1996年,39名美国学生开始了一项非常有趣的计划—绿树计划。学生们在秋天以收集核桃开始了此项计划。在11月中的时候,这些坚果被埋在学校花园里的笼子里。通过这种方式,这些种子可以在阴凉湿润的情况下储存几个月,在来年2月,这些种子被挖出来,然后他们开始发芽。发芽的种子保存在冰箱里,这样可以阻止种子的生长,直到播种季节到来的时候再把他们播种。这样可以帮助这些树苗在播种时尺寸一样大。3月时,发芽的种子被种到纸杯中。每个学生被要求种12棵树。这些树被细心的浇灌和照看。大约1个礼拜后第一课核桃树长出来了。学生们发现了这项计划令人激动人心的部分。4月29日,这些树被移植到湖边。仅仅用了一个半小时,学生们就种好了所有的树。亲眼看到一个不毛之地变成一片森林是多么有趣的事啊!

在1996年,39个美国学生开始了一个非常有趣的工程——绿树工程。在秋天,学生们开始了他们的工程,首先就是收集核桃。在11月中旬的时候,将核桃埋在学校花园的箱子里。通过这种方式,种子可在它们开始生长前的几个月时间里保持凉爽和湿润。到二月份,再把种子挖出来,这样他们就可以开始萌芽了。发芽的种子将被保存在冰箱里,以使它们停止生长,直到种植时间。这有助于保持播种时有相同大小尺寸的树。到了三月份,将发芽的种子种植在纸杯中。每个学生种12棵树。然后,树木都要经过精心的浇灌和看护。经过一个星期左右,核桃树开始出现。学生们发现这部分工程非常令人兴奋。到4月29日,树木被移植到湖边。他们只花了90分钟,种完了所有的树。当看到一个光秃秃的区域变成一片森林呈现眼前时,这是多么有意思的事情呀!
