    Activity 81.Grasp the main idea of the listening.Listen to the tape and answer the following questions:Who are the two speakers in the listening? What is their relationship?What is the main idea of the first part of the listening? How about the second part?2.Complete the passage.Ask the students to quickly review the summaries of the two listening materials in activity 2. Then play the recording for the second time.Ask them to complete the passage and fill in the blanks.3.Play the recording again and ask the students to use the structure diagram to comb the information structure in the listening.(While listening, take notes. Capture key information quickly and accurately.)Step 8 Talking Activity 91.Focus on the listening text.Listen to the students and listen to the tape. Let them understand the attitudes of Wu Yue and Justin in the conversation.How does Wu Yue feel about Chinese minority cultures?What does Justin think of the Miao and Dong cultures?How do you know that?2.learn functional items that express concerns.Ask students to focus on the expressions listed in activity. 3.And try to analyze the meaning they convey, including praise (Super!).Agree (Exactly!)"(You're kidding.!)Tell me more about it. Tell me more about it.For example, "Yeah Sure." "Definitely!" "Certainly!" "No kidding!" "No wonder!" and so on.4.Ask the students to have conversations in small groups, acting as Jsim and his friends.Justin shares his travels in Guizhou with friends and his thoughts;Justin's friends should give appropriate feedback, express their interest in relevant information, and ask for information when necessary.In order to enrich the dialogue, teachers can expand and supplement the introduction of Miao, dong, Lusheng and Dong Dage.After the group practice, the teacher can choose several groups of students to show, and let the rest of the students listen carefully, after listening to the best performance of the group, and give at least two reasons.

    新知講授(一)——隨機(jī)試驗(yàn) 我們把對(duì)隨機(jī)現(xiàn)象的實(shí)現(xiàn)和對(duì)它的觀察稱為隨機(jī)試驗(yàn),簡(jiǎn)稱試驗(yàn),常用字母E表示。我們通常研究以下特點(diǎn)的隨機(jī)試驗(yàn):(1)試驗(yàn)可以在相同條件下重復(fù)進(jìn)行;(2)試驗(yàn)的所有可能結(jié)果是明確可知的,并且不止一個(gè);(3)每次試驗(yàn)總是恰好出現(xiàn)這些可能結(jié)果中的一個(gè),但事先不確定出現(xiàn)哪個(gè)結(jié)果。新知講授(二)——樣本空間思考一:體育彩票搖獎(jiǎng)時(shí),將10個(gè)質(zhì)地和大小完全相同、分別標(biāo)號(hào)0,1,2,...,9的球放入搖獎(jiǎng)器中,經(jīng)過(guò)充分?jǐn)嚢韬髶u出一個(gè)球,觀察這個(gè)球的號(hào)碼。這個(gè)隨機(jī)試驗(yàn)共有多少個(gè)可能結(jié)果?如何表示這些結(jié)果?根據(jù)球的號(hào)碼,共有10種可能結(jié)果。如果用m表示“搖出的球的號(hào)碼為m”這一結(jié)果,那么所有可能結(jié)果可用集合表示{0,1,2,3,4,5,6,7,8,9}.我們把隨機(jī)試驗(yàn)E的每個(gè)可能的基本結(jié)果稱為樣本點(diǎn),全體樣本點(diǎn)的集合稱為試驗(yàn)E的樣本空間。

    問(wèn)題導(dǎo)學(xué)類(lèi)比用方程研究橢圓雙曲線幾何性質(zhì)的過(guò)程與方法,y2 = 2px (p>0)你認(rèn)為應(yīng)研究拋物線的哪些幾何性質(zhì),如何研究這些性質(zhì)?1. 范圍拋物線 y2 = 2px (p>0) 在 y 軸的右側(cè),開(kāi)口向右,這條拋物線上的任意一點(diǎn)M 的坐標(biāo) (x, y) 的橫坐標(biāo)滿足不等式 x ≥ 0;當(dāng)x 的值增大時(shí),|y| 也增大,這說(shuō)明拋物線向右上方和右下方無(wú)限延伸.拋物線是無(wú)界曲線.2. 對(duì)稱性觀察圖象,不難發(fā)現(xiàn),拋物線 y2 = 2px (p>0)關(guān)于 x 軸對(duì)稱,我們把拋物線的對(duì)稱軸叫做拋物線的軸.拋物線只有一條對(duì)稱軸. 3. 頂點(diǎn)拋物線和它軸的交點(diǎn)叫做拋物線的頂點(diǎn).拋物線的頂點(diǎn)坐標(biāo)是坐標(biāo)原點(diǎn) (0, 0) .4. 離心率拋物線上的點(diǎn)M 到焦點(diǎn)的距離和它到準(zhǔn)線的距離的比,叫做拋物線的離心率. 用 e 表示,e = 1.探究如果拋物線的標(biāo)準(zhǔn)方程是〖 y〗^2=-2px(p>0), ②〖 x〗^2=2py(p>0), ③〖 x〗^2=-2py(p>0), ④

    二、直線與拋物線的位置關(guān)系設(shè)直線l:y=kx+m,拋物線:y2=2px(p>0),將直線方程與拋物線方程聯(lián)立整理成關(guān)于x的方程k2x2+2(km-p)x+m2=0.(1)若k≠0,當(dāng)Δ>0時(shí),直線與拋物線相交,有兩個(gè)交點(diǎn);當(dāng)Δ=0時(shí),直線與拋物線相切,有一個(gè)切點(diǎn);當(dāng)Δ<0時(shí),直線與拋物線相離,沒(méi)有公共點(diǎn).(2)若k=0,直線與拋物線有一個(gè)交點(diǎn),此時(shí)直線平行于拋物線的對(duì)稱軸或與對(duì)稱軸重合.因此直線與拋物線有一個(gè)公共點(diǎn)是直線與拋物線相切的必要不充分條件.二、典例解析例5.過(guò)拋物線焦點(diǎn)F的直線交拋物線于A、B兩點(diǎn),通過(guò)點(diǎn)A和拋物線頂點(diǎn)的直線交拋物線的準(zhǔn)線于點(diǎn)D,求證:直線DB平行于拋物線的對(duì)稱軸.【分析】設(shè)拋物線的標(biāo)準(zhǔn)方程為:y2=2px(p>0).設(shè)A(x1,y1),B(x2,y2).直線OA的方程為: = = ,可得yD= .設(shè)直線AB的方程為:my=x﹣ ,與拋物線的方程聯(lián)立化為y2﹣2pm﹣p2=0,
