（2）怎樣理解本文的一些相關(guān)論述？【明確】這是一篇科學(xué)講演，涉及較為復(fù)雜的背景知識(shí)。這些知識(shí)和講演的主題是密切相關(guān)的，如果不作必要的交待，講演的內(nèi)容就會(huì)顯得抽象和單薄。如，談到天氣預(yù)報(bào)、大腦工作原理都具有混沌性質(zhì)，來反襯宇宙在大尺度上是"平滑而非混沌"的；如，談到恒星的死亡（歸宿）引出黑洞，為宇宙中暗物質(zhì)的存在尋找理論支持；如，談到現(xiàn)存宇宙對(duì)初始密度的極度敏感，引出了"人擇原理"等等。這些相關(guān)的論述，或從對(duì)立面凸顯觀點(diǎn)，或從縱深面強(qiáng)化觀點(diǎn)，使論證豐富多彩。（3）這篇講演在語言上具有怎樣的特點(diǎn)？【明確】講演是面對(duì)面的交流，這種交流又是單向度的，如果不注意講演的語言藝術(shù)，就達(dá)不到最佳的表達(dá)效果。這篇講演，除了推理嚴(yán)謹(jǐn)外，語言幽默也是其突出的特點(diǎn)。幽默的語言創(chuàng)造出一種輕松愉快的氣氛，更具有親和力，使所闡發(fā)的事理更容易為聽眾接受。

六、到此為止，我們了解到，作者對(duì)“笑”鯤鵬和別人的蜩與學(xué)鳩、斥鴳、宋榮子都一一作了否定。那么請(qǐng)大家討論一下，1、作者對(duì)鯤鵬和“知效一官，行比一鄉(xiāng)，德合一君，而征一國者”是不是肯定呢？明確：也都作了否定。否定后者好理解，關(guān)鍵是否定前者不好理解，因?yàn)椤蚌H鵬展翅”早已作為積極的意象被人們廣泛引用。但在本文中，作者在講述這一寓言故事時(shí)，突出的不是鯤鵬本身，而是風(fēng)力，“故九萬里，風(fēng)斯在下矣，而后乃今培風(fēng)；背負(fù)青天，而莫之夭閼者，而后乃今將圖南”。對(duì)風(fēng)力作用的突出，實(shí)際上就是對(duì)鯤鵬的否定。作者寫了“笑”的雙方，對(duì)“笑”的一方蜩與學(xué)鳩、斥鴳、宋榮子都作了否定，對(duì)被“笑”的一方鯤鵬和“知效一官，行比一鄉(xiāng)，德合一君，而征一國者”也都作了否定，并且對(duì)順便提及的野馬、塵埃、芥、大舟、朝菌、蟪蛄、冥靈、大椿、彭祖、列子等事物或者人物也都作了否定。這種全盤否定的態(tài)度，如果我們借用本文中的一個(gè)形象的詞語，可以說是：笑！是的，本文也可以說是：莊子“笑”萬物！

1．改善城市環(huán)境：治理河流、控制大氣污染物、大力加強(qiáng)綠化建設(shè)為改善城市環(huán)境，上海市全面展開對(duì)大氣、河流、噪聲等多方面的治理工作。如蘇州河的治理、降低城市污染物濃度、加強(qiáng)綠化建設(shè)，截止1990年，市區(qū)綠化覆蓋率達(dá)到20.3%。2．改善城市交通、改善居住條件擴(kuò)寬主干道，修建環(huán)城公路，修筑了南浦大橋和揚(yáng)浦大橋，新修城市高架公路和地鐵，改造住宅。3．控制城市規(guī)模建立衛(wèi)星城，開發(fā)新區(qū)，有效地控制城市中心區(qū)的規(guī)模。思考：什么時(shí)候許多國家采取措施保護(hù)和改善城市環(huán)境？你認(rèn)為可以采取哪些措施來保護(hù)和改善城市環(huán)境？上海市保護(hù)和改善城市環(huán)境的措施：上海的衛(wèi)星城有哪些？上海新建了哪個(gè)新區(qū)？目前浦東新區(qū)在上海的地位如何？建立衛(wèi)星城和開發(fā)新區(qū)可以起到什么作用？上海市為改善交通條件，做了哪些工作？
人教版新課標(biāo)高中物理必修1摩擦力教案2篇
l．知識(shí)與技能：（1）知道摩擦力產(chǎn)生的條件。（2）能在簡單問題中，根據(jù)物體的運(yùn)動(dòng)狀態(tài)，判斷靜摩擦力的有無、大小和方向；知道存在著最大靜摩擦力。（3）掌握動(dòng)磨擦因數(shù)，會(huì)在具體問題中計(jì)算滑動(dòng)磨擦力，掌握判定摩擦力方向的方法。（4）知道影響到摩擦因數(shù)的因素。2．過程與方法：通過觀察演示實(shí)驗(yàn)，概括出摩擦力產(chǎn)生的條件及摩擦力的特點(diǎn)，培養(yǎng)學(xué)生的觀察、概括能力。通過靜摩擦力與滑動(dòng)摩擦力的區(qū)別對(duì)比，培養(yǎng)學(xué)生分析綜合能力。3．情感態(tài)度價(jià)值觀：在分析物體所受摩擦力時(shí)，突出主要矛盾，忽略次要因素及無關(guān)因素，總結(jié)出摩擦力產(chǎn)生的條件和規(guī)律。二、重點(diǎn)、難點(diǎn)分析1．本節(jié)課的內(nèi)容分滑動(dòng)摩擦力和靜摩擦力兩部分。重點(diǎn)是摩擦力產(chǎn)生的條件、特性和規(guī)律，通過演示實(shí)驗(yàn)得出關(guān)系f=μN(yùn)。2．難點(diǎn)是學(xué)生有初中的知識(shí)，往往誤認(rèn)為壓力N的大小總是跟滑動(dòng)物體所受的重力相等，因此必須指出只有當(dāng)兩物體的接觸面垂直，物體在水平拉力作用下，沿水平面滑動(dòng)時(shí)，壓力N的大小才跟物體所受的重力相等。
