知識與技能1．知道地心說和日心說的基本內(nèi)容．2．知道所有行星繞太陽運(yùn)動的軌道都是橢圓，太陽處在橢圓的一個(gè)焦點(diǎn)上．3．知道所有行星的軌道的半長軸的三次方跟它的公轉(zhuǎn)周期的二次方的比值都相等，且這個(gè)比值與行星的質(zhì)量無關(guān)，但與太陽的質(zhì)量有關(guān)．4．理解人們對行星運(yùn)動的認(rèn)識過程是漫長復(fù)雜的，真理是來之不易的．過程與方法通過托勒密、哥白尼、第谷·布拉赫、開普勒等幾位科學(xué)家對行星運(yùn)動的不同認(rèn)識，了解人類認(rèn)識事物本質(zhì)的曲折性并加深對行星運(yùn)動的理解．情感、態(tài)度與價(jià)值觀1．澄清對天體運(yùn)動裨秘、模糊的認(rèn)識，掌握人類認(rèn)識自然規(guī)律的科學(xué)方法．2．感悟科學(xué)是人類進(jìn)步不竭的動力．教學(xué)重點(diǎn)理解和掌握開普勒行星運(yùn)動定律，認(rèn)識行星的運(yùn)動．學(xué)好本節(jié)有利于對宇宙中行星的運(yùn)動規(guī)律的認(rèn)識，掌握人類認(rèn)識自然規(guī)律的科學(xué)方法，并有利于對人造衛(wèi)星的學(xué)習(xí)．
人教版高中語文必修5《林教頭風(fēng)雪山神廟》教案
②林沖無辜受害，被刺配到滄州，遠(yuǎn)離了京城，高俅一伙，陸謙、富安又追到滄州，在李小二的酒店里密謀陷害林沖。林沖從李小二那里聽說了這件事之后是什么態(tài)度？表現(xiàn)出林沖的什么性格？明確：林沖聽到李小二的報(bào)信，并確知從東京來的尷尬人就是陸虞候時(shí)，馬上意識到“那潑賤賊”是要“來這里害我”，他識破了仇人的陰謀，激起了復(fù)仇的怒火，氣憤地說：“休要撞著我，只叫他骨肉為泥！”說罷，便怒沖沖地“先去街上買把解腕尖刀，帶在身上，前街后巷一地里去尋”，次日，“帶了刀，又去滄州城里城外，小街夾巷，團(tuán)團(tuán)尋了一日”。這說明，當(dāng)迫害逼到眼前時(shí)，林沖也具有了強(qiáng)烈的反抗意識。但是，“街上尋了三五日，不見消耗”時(shí)，“林沖也自心下慢了”，對仇人有所懷疑，卻失去了應(yīng)有的警惕性，剛剛點(diǎn)燃起來的復(fù)仇怒火又慢慢熄滅了。這說明林沖的反抗并不堅(jiān)決，幻想得過且過，委曲求全。
