人教版高中語文必修5《談中國詩》教案
教師提示：1.這句話的本體不是一般意義上的“中國詩”，即不是指中國詩歌中的某一類作品或某位詩人的作品，而是指中國詩的發(fā)展特點(diǎn)。早熟，是指“純粹的抒情詩的精髓和峰極，在中國詩里出現(xiàn)得異常之早”；早衰，是指“中國詩一蹴而至崇高的境界，以后就缺乏變化，而且逐漸腐化”(腐化，是對詩的思想內(nèi)容和藝術(shù)價值而言的)。這句話，借助比喻和比喻中的對比(“早熟”與“早衰”)，從詩歌發(fā)展的角度，簡要地說明了中國詩的藝術(shù)特征和由此產(chǎn)生的負(fù)面影響。2.這句話有兩層意思：一是借梵文的《百喻經(jīng)》闡釋中國的藝術(shù)和思想體構(gòu)上的缺欠，旨在批評；二是點(diǎn)明造成這種缺欠的根本原因?！耙粋€印度愚人要住三層樓而不許匠人造底下兩層”這樣的建筑物就是“飄飄凌云的空中樓閣”，作者以此作喻，批評中國的藝術(shù)和思想體構(gòu)缺乏嚴(yán)密的邏輯性，往往脫離客觀實(shí)際，沒有堅實(shí)的基礎(chǔ)，其結(jié)果必定影響藝術(shù)的健康、穩(wěn)定地發(fā)展。

(2)方法一:第一次取到一件不合格品,還剩下99件產(chǎn)品,其中有4件不合格品,95件合格品,于是第二次又取到不合格品的概率為4/99,由于這是一個條件概率,所以P(B|A)=4/99.方法二:根據(jù)條件概率的定義,先求出事件A,B同時發(fā)生的概率P(AB)=(C_5^2)/(C_100^2 )=1/495,所以P(B|A)=(P"(" AB")" )/(P"(" A")" )=(1/495)/(5/100)=4/99.6.在某次考試中,要從20道題中隨機(jī)地抽出6道題,若考生至少答對其中的4道題即可通過;若至少答對其中5道題就獲得優(yōu)秀.已知某考生能答對其中10道題,并且知道他在這次考試中已經(jīng)通過,求他獲得優(yōu)秀成績的概率.解:設(shè)事件A為“該考生6道題全答對”,事件B為“該考生答對了其中5道題而另一道答錯”,事件C為“該考生答對了其中4道題而另2道題答錯”,事件D為“該考生在這次考試中通過”,事件E為“該考生在這次考試中獲得優(yōu)秀”,則A,B,C兩兩互斥,且D=A∪B∪C,E=A∪B,由古典概型的概率公式及加法公式可知P(D)=P(A∪B∪C)=P(A)+P(B)+P(C)=(C_10^6)/(C_20^6 )+(C_10^5 C_10^1)/(C_20^6 )+(C_10^4 C_10^2)/(C_20^6 )=(12" " 180)/(C_20^6 ),P(E|D)=P(A∪B|D)=P(A|D)+P(B|D)=(P"(" A")" )/(P"(" D")" )+(P"(" B")" )/(P"(" D")" )=(210/(C_20^6 ))/((12" " 180)/(C_20^6 ))+((2" " 520)/(C_20^6 ))/((12" " 180)/(C_20^6 ))=13/58,即所求概率為13/58.
