当数九隆冬刺骨的寒风一天比一天猛烈的时候,春天也就离我们不远了。可是,你知道春天从哪儿起步,又是以怎样的步伐向我们走来的吗?下面这个“动手做”将带领我们去追寻春天的脚印,记录下绿色生命的旅痕。 北方流传的一首“九九歌”中有一段唱道:“五九和六九,河边看杨柳”,而今年的立春正值“五九”、“六九”之间,也就是你刚刚拿到这一期《知识就是力量》的时候,我们的跟踪行动适时地开始了。我们都知道绿色是春天的象征,植物由黄转绿之时就是春回大地之日,所以,这个追寻春天的“动手做”就从绿色植物开始。首先需做好思想准备的是一定要持之以恒,全部跟踪过程要两个月时间;其次,制作过程要精心细致,注意安全。
When the winter winds of Jiulong are fierce day by day, spring is not far from us. However, do you know where to start in the spring and how are we going to come to us? The following “hands-on” will lead us to pursue the footprints of the spring and record the traces of green life. A song in the “Nine or 9 Songs” circulated in the north sang: “May 9 and June 9th, by the river to see Willow,” and this year’s spring breaks up between “May 9th” and “June 9th,” which is just what you When we got this issue of “Knowledge is Power,” our tracking action began in due course. We all know that green is a symbol of spring. When plants turn from yellow to green, it is the day of spring return to the earth. Therefore, this “hands-on” to pursue spring begins with green plants. First of all, it is necessary to be prepared for the idea. It must take two months to follow up the process. Second, the production process must be meticulous and careful, pay attention to safety.
