三年級學(xué)生觀察日記中英文

  今天科學(xué)課,李老師走進(jìn)教室就問了我們兩個問題:

三年級學(xué)生觀察日記中英文

  “你們猜一猜,每棵油菜上大約有多少個菜莢?每個菜莢里有多少顆菜籽?”

  老師的話剛說完,大家就七嘴八舌地回答起來:“21個菜莢,20顆菜籽!

  “50個菜莢,16顆菜籽!

  “100多個菜莢,30幾顆菜籽!薄

  李老師神秘地笑了笑,說:“我們還是到田里去解決這個問題吧!”

  我們來到田邊,一看,二十多天前,這里還是一片金黃,現(xiàn)在每一棵油菜的`枝條上結(jié)滿了一個個飽滿的菜莢了,看起來有點(diǎn)沉。仔細(xì)觀察菜莢,只見一顆顆種子脹滿了它的“外衣”,圓鼓鼓的凸了出來,頂端尖尖的;剝?nèi)ァ巴庖隆报D―菜莢,里面的種子圓溜溜的,像一顆顆小珍珠晶瑩發(fā)亮,十分好看。

  我和仇琦兩人一組合作數(shù),我們兩個兩個地數(shù),很快就數(shù)完了三株油菜。當(dāng)我數(shù)到最后一棵的時候,大吃一驚,這株足足有400多個菜莢,它們密密麻麻地掛在莖上伸出的枝條上。我還從上面采來了一個菜莢,剝開數(shù)了數(shù)有27顆菜籽。

  Today, science classes, the teacher asked us to walk into a classroom on two issues : "You guess.Rape about the number of dishes for each pod? how many there are in each pod vegetables rapeseed? "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.
