農(nóng)業(yè)科學的周期是以年為時間單位，一次實驗就要等到一次花開、結(jié)果。就這樣，幾個實驗誤導了袁隆平好幾年。這時登在《參考消息》上的一篇不起眼的文章像給迷途中的袁隆平以當頭一棒：克里克、沃森和威爾金斯發(fā)現(xiàn)DNA螺旋結(jié)構(gòu)，西方的遺傳學研究進入分子水平?！拔耶敃r還在那里搞什么無性雜交，糟糕得很”。水稻是自花授粉植物，雄蕊雌蕊都在一朵花里面，雌雄同株，沒有雜種優(yōu)勢一雜種優(yōu)勢是生物界的普遍現(xiàn)象，小到細菌，大到人，近親繁殖的結(jié)果是種群的退化。但是水稻因為花小，其雜交是當時公認的世界難題，設在馬尼拉的世界水稻研究中心就是因為困難重重，差點關閉。袁隆平偏不信這個邪，他突發(fā)靈感：專門培養(yǎng)一種特殊的水稻品種——雄花退化的雄性不育系，沒有自己的花粉，這樣不就可以做到雜種優(yōu)勢了嗎?于是，漫長的尋找過程開始了，要找到這樣一株雄花退化而且雜交之后產(chǎn)量猛增的“太監(jiān)”水稻簡直是大海撈針。
人教版新課標高中物理必修1牛頓第二定律教案2篇
1．這節(jié)課以實驗為依據(jù)，采用控制變量的方法進行研究。這一方法今后在電學、熱學的研究中還要用到。我們根據(jù)已掌握的知識設計實驗、探索規(guī)律是物體研究的重要方法。2．定義力的單位“牛頓”使得k=1，得到牛頓第二定律的簡單形式F=ma。使用簡捷的數(shù)學語言表達物理規(guī)律是物理學的特征之一，但應知道它所對應的文字內(nèi)容和意義。3．牛頓第二定律概括了運動和力的關系。物體所受合外力恒定，其加速度恒定；合外力為零，加速度為零。即合外力決定了加速度，而加速度影響著物體的運動情況。因此，牛頓第二定律是把前兩章力和物體的運動構(gòu)成一個整體，其中的紐帶就是加速度。四、評價方案及說明1、對科學知識與技能的評價要注重科學內(nèi)容的理解與應用，而不是單純記憶。技能的評價目標包括觀察技能、實驗技能等方面。對科學的技能的評價要盡量融合在科學探究過程的情景中。對科學知識的評價主要從兩方面，一是根據(jù)學生診斷性練習；二是通過學生作業(yè)反映學生掌握情況。
