把解集在數(shù)軸上表示出來(lái)，并將解集中的整數(shù)解寫(xiě)出來(lái)．解析：分別計(jì)算出兩個(gè)不等式的解集，再根據(jù)大小小大中間找確定不等式組的解集，再找出解集范圍內(nèi)的整數(shù)即可．解：x＋23<1 ①，2（1－x）≤5 ②，由①得x＜1，由②得x≥－32，∴不等式組的解集為－32≤x＜1.則不等式組的整數(shù)解為－1，0.方法總結(jié)：此題主要考查了一元一次不等式組的解法，解決此類(lèi)問(wèn)題的關(guān)鍵在于正確解得不等式組或不等式的解集，然后再根據(jù)題目中對(duì)于解集的限制得到下一步所需要的條件，再根據(jù)得到的條件進(jìn)而求得不等式組的整數(shù)解．三、板書(shū)設(shè)計(jì)一元一次不等式組概念解法不等式組的解集利用數(shù)軸確定解集利用口訣確定解集解一元一次不等式組是建立在解一元一次不等式的基礎(chǔ)之上．解不等式組時(shí)，先解每一個(gè)不等式，再確定各個(gè)不等式組的解集的公共部分.

方法總結(jié)：已知解集求字母系數(shù)的值，通常是先解含有字母的不等式，再利用解集唯一性列方程求字母的值．解題過(guò)程體現(xiàn)了方程思想．三、板書(shū)設(shè)計(jì)1．一元一次不等式的概念2．解一元一次不等式的基本步驟：(1)去分母；(2)去括號(hào)；(3)移項(xiàng)；(4)合并同類(lèi)項(xiàng)；(5)兩邊都除以未知數(shù)的系數(shù)．本節(jié)課通過(guò)類(lèi)比一元一次方程的解法得到一元一次不等式的解法，讓學(xué)生感受到解一元一次不等式與解一元一次方程只是在兩邊都除以未知數(shù)的系數(shù)這一步時(shí)有所不同．如果這個(gè)系數(shù)是正數(shù)，不等號(hào)的方向不變；如果這個(gè)系數(shù)是負(fù)數(shù)，不等號(hào)的方向改變．這也是這節(jié)課學(xué)生容易出錯(cuò)的地方．教學(xué)時(shí)要大膽放手，不要怕學(xué)生出錯(cuò)，通過(guò)學(xué)生犯的錯(cuò)誤引起學(xué)生注意，理解產(chǎn)生錯(cuò)誤的原因，以便在以后的學(xué)習(xí)中避免出錯(cuò).

北師大初中九年級(jí)數(shù)學(xué)下冊(cè)二次函數(shù)與一元二次方程1教案
解：(1)設(shè)第一次落地時(shí)，拋物線的表達(dá)式為y＝a(x－6)2＋4，由已知：當(dāng)x＝0時(shí)，y＝1，即1＝36a＋4，所以a＝－112.所以函數(shù)表達(dá)式為y＝－112(x－6)2＋4或y＝－112x2＋x＋1；(2)令y＝0，則－112(x－6)2＋4＝0，所以(x－6)2＝48，所以x1＝43＋6≈13，x2＝－43＋6<0(舍去)．所以足球第一次落地距守門(mén)員約13米；(3)如圖，第二次足球彈出后的距離為CD，根據(jù)題意：CD＝EF(即相當(dāng)于將拋物線AEMFC向下平移了2個(gè)單位)．所以2＝－112(x－6)2＋4，解得x1＝6－26，x2＝6＋26，所以CD＝|x1－x2|＝46≈10.所以BD＝13－6＋10＝17(米)．方法總結(jié)：解決此類(lèi)問(wèn)題的關(guān)鍵是先進(jìn)行數(shù)學(xué)建模，將實(shí)際問(wèn)題中的條件轉(zhuǎn)化為數(shù)學(xué)問(wèn)題中的條件．常有兩個(gè)步驟：(1)根據(jù)題意得出二次函數(shù)的關(guān)系式，將實(shí)際問(wèn)題轉(zhuǎn)化為純數(shù)學(xué)問(wèn)題；(2)應(yīng)用有關(guān)函數(shù)的性質(zhì)作答．

區(qū)分賓語(yǔ)從句、定于從句和狀語(yǔ)從句賓語(yǔ)從句和狀語(yǔ)從句，都叫做主從復(fù)合句。賓語(yǔ)從句主要是中考必考的，是初中階段必掌握的從句，賓語(yǔ)從句主要是掌握三要素，所謂賓語(yǔ)從句，就是賓語(yǔ)在主從復(fù)合句當(dāng)中充當(dāng)賓語(yǔ)的一個(gè)句子，叫做賓語(yǔ)從句。主句的謂語(yǔ)動(dòng)詞是及物動(dòng)詞，后面如果是詞或者是短語(yǔ)的話，是簡(jiǎn)單句，如果是句子的話，肯定是賓語(yǔ)從句。I know that he good at English.就是賓語(yǔ)從句，三要素，一要素是要注意連詞，連詞一共學(xué)了三類(lèi)連詞，一類(lèi)連詞是that口語(yǔ)當(dāng)中可以省略，就像剛才說(shuō)的那一句，I hear he is good at English.還有疑問(wèn)代詞、疑問(wèn)副詞，how where when，疑問(wèn)代詞、疑問(wèn)副詞。還有一類(lèi)連詞weather是否的意思，不是狀語(yǔ)從句當(dāng)中的如果，這一定要和如果區(qū)分開(kāi)，這是是否。I don't know if he interested at English。賓語(yǔ)從句要注意if是連詞。第二要素是語(yǔ)序，要用陳述舉語(yǔ)序。比如說(shuō)你家有幾口人，我們都說(shuō)How many people are there in you family?但是這是簡(jiǎn)單句，一旦說(shuō)成賓語(yǔ)從句，你可以告訴我你家有幾口人嗎？Could you tell me how many people there are in you family ?
