数菜籽11 月9 日 晴
今天科学课，李老师走进教室就问了我们两个问题：“你们猜一猜，每棵油菜上大约有多少个菜荚？每个菜荚里有多少颗菜籽？”老师的话刚说完，大家就七嘴八舌地回答起来：“21 个菜荚，20 颗菜籽。”“50 个菜荚，16 颗菜籽。”“100多个菜荚，30 几颗菜籽。”„„李老师神秘地笑了笑，说：“我们还是到田里去解决这个问题吧！”我们来到田边，一看，二十多天前，这里还是一片金黄，现在每一棵油菜的枝条上结满了一个个饱满的菜荚了，看起来有点沉。仔细观察菜荚，只见一颗颗种子胀满了它的“外衣”，圆鼓鼓的凸了出来，顶端尖尖的；剥去“外衣”——菜荚，里面的种子圆溜溜的，像一颗颗小珍珠晶莹发亮，十分好看。我和仇琦两人一组合作数，我们两个两个地数，很快就数完了三株油菜。当我数到最后一棵的时候，大吃一惊，这株足足有400 多个菜荚，它们密密麻麻地挂在茎上伸出的枝条上。我还从上面采来了一个菜荚，剥开数了数有27 颗菜籽。――刘 召

"the teacher said just now.We will go on to answer : "21 dishes dioxin, 20 were rapeseed. "" Vanilla 50 dishes.Rapeseed 16 satellites. "" Vanilla more than 100 dishes, a few of rapeseed 30. ": : The teacher smiled mysteriously and said :"We have to solve this problem or to the fields!" We have come to the edge, a look at two days ago,here was still golden, every tree branches rape of a month full of dishes full unity of the pod looks a bit Shen.Careful observation pod vegetables, I saw so many seeds of its legs "while" a convex circular swelling, and the sharp tip;Has the "cloak" of dioxin -- vegetables, seeds inside the circle Liuliu, like so many small shiny glistening pearls, very pretty.Theirs was a combination of me and a few Qiuqi, two at several quickly finished several lengthy rape.When I find that the tree came over 400 pages of this strain of dioxin in food,They're helping to hang on branches stems.I have to adopt a vegetable dioxin from above, catching 27 rapeseed augmented.
