一、回顧舊知，復(fù)習(xí)鋪墊1、上節(jié)課我們學(xué)習(xí)了一些比例的知識(shí)，誰能說一說什么叫做比例？比例的基本性質(zhì)是什么？應(yīng)用比例的基本性質(zhì)可以做什么？2、判斷下面每組中的兩個(gè)比是否能組成比例？為什么？6:3和8:4 : 和 :3、這節(jié)課我們繼續(xù)學(xué)習(xí)有關(guān)比例的知識(shí)，學(xué)習(xí)解比例。（板書課題）二、引導(dǎo)探索，學(xué)習(xí)新知1、什么叫解比例？我們知道比例共有四項(xiàng)，如果知道其中的任何三項(xiàng)，就可以求出這個(gè)比例中的另外一個(gè)未知項(xiàng)。求比例中的未知項(xiàng)，叫做解比例。解比例要根據(jù)比例的基本性質(zhì)來解。2、教學(xué)例2。（1）把未知項(xiàng)設(shè)為X。解：設(shè)這座模型的高是X米。（2）根據(jù)比例的意義列出比例：X:320=1:10（3）讓學(xué)生指出這個(gè)比例的外項(xiàng)、內(nèi)項(xiàng)，并說明知道哪三項(xiàng)，求哪一項(xiàng)。根據(jù)比例的基本性質(zhì)可以把它變成什么形式？3x＝8×15。這變成了什么？（方程。）教師說明：這樣解比例就變成解方程了，利用以前學(xué)過的解方程的方法就可以求出未知數(shù)X的值。

（三）作家介紹，寫作背景大家說“雨巷”這首詩寫得美不美？（美）剛才我也說了，這首詩是中國朦朧詩的百年經(jīng)典。那么對(duì)于這么出名的詩，有誰能夠向我們介紹一下它的作者跟寫作背景呢？（明確：戴望舒，原名戴朝實(shí)又名戴夢(mèng)鷗，1905年出生于杭州。1929年4月出版第一本詩集《我底記憶》，他的成名作《雨巷》即收入此集中。1933年8月出版了《望舒草》1948年出版了《災(zāi)難歲月》一生留下了詩篇92首。《雨巷》是戴望舒的成名作和前期的代表作,他曾因此而贏得了“雨巷詩人”的雅號(hào)。這首詩寫于1927年夏天。當(dāng)時(shí)全國處于白色恐怖之匯總，戴望舒因曾參加進(jìn)步活動(dòng)而不得不避居于松江的友人家中，在孤寂中咀嚼著大革命失敗后的幻滅與痛苦，心匯總充滿了迷惘的情緒和朦朧的希望。）（適當(dāng)板書）
