成人高考英語(yǔ)
第七章 數(shù)詞的基本用法:序數(shù)詞 教學(xué)設(shè)計(jì)
安遠(yuǎn)中等職業(yè)學(xué)校 杜譞
教學(xué)內(nèi)容:序數(shù)詞
教學(xué)目標(biāo):能聽、說、認(rèn)讀序數(shù)詞。
教學(xué)重點(diǎn):掌握序數(shù)詞的構(gòu)成及其基本用法。
教學(xué)難點(diǎn):基數(shù)詞轉(zhuǎn)化為序數(shù)詞,分?jǐn)?shù)的構(gòu)成,日期的表達(dá)。
教學(xué)方法:對(duì)比法、歸納演繹、TPR
教學(xué)準(zhǔn)備:圖片、單詞卡、課件
教學(xué)過程:
Step 1.Preparation 1.Greetings: Say hello.2.Sing a song.3.Review the numbers。讓學(xué)生把課件上的單詞用英語(yǔ)讀出來。(這個(gè)環(huán)節(jié)既復(fù)習(xí)了上一課內(nèi)容基數(shù)詞,又為序數(shù)詞的新授做鋪墊。)
4.Ask and answer“How old ??? I’m ??”“How many ??? ”“How much ??”(學(xué)生根據(jù)實(shí)際情況回答)(目的復(fù)習(xí)基數(shù)詞在實(shí)際情境中的運(yùn)用的。)最后教師拿出圖問: Where is the living room? It’s on the first floor.Step 2.Presentation
1.單詞導(dǎo)呈
(1)教學(xué)單詞 first.利用圖片直接介紹This is a living room.It’s on the first floor.老師指著圖片介紹,學(xué)生跟讀單詞,老師同時(shí)板書單詞。
(2)運(yùn)用“Where is the living room? 引出It’s on the first/second floor.”利用相同方法教授單詞second和third。(在學(xué)習(xí)這幾個(gè)單詞時(shí),可以采用TPR的方法,增加趣味)
(3)出示序數(shù)詞概念:表示數(shù)目順序的詞,我們稱為序數(shù)詞。(明確序數(shù)詞概念)
(4)運(yùn)用單詞圖片簡(jiǎn)單復(fù)習(xí)剛學(xué)的新詞。
(5)課件出示基數(shù)詞,并逐個(gè)出示20以內(nèi)的序數(shù)詞(通過游戲PK的方式鞏固序數(shù)詞單詞)
(6)教授整十和幾十幾的序數(shù)詞。(老師要讓學(xué)生明白序數(shù)詞和基數(shù)詞的不同,并通過觀察歸納出基數(shù)詞變序數(shù)詞的方法。)2.歸納出基數(shù)詞變序數(shù)詞的口訣。
基變序,有規(guī)律。
1,2,3,特殊記,詞尾字母t,d,d;(first,second,third)8減t,9去e,f來把ve替;
(eighth,ninth)
(fifth,twelfth)單詞ty作結(jié)尾,ty變成tie;(twentieth)
若是碰到幾十幾,只變個(gè)位就可以。(thirty-first,sixty-fourth)(口訣有助于學(xué)生對(duì)序數(shù)詞構(gòu)成方法的記憶)
合作學(xué)習(xí)。
The students read the words in groups.3.序數(shù)詞的簡(jiǎn)寫形式:是由阿拉伯?dāng)?shù)字之后加上單詞最后兩個(gè)字母組成,讀音不變。
4.序數(shù)詞的基本用法:
(1).用來表示事物的順序:the second lesson
(2).表示年代世紀(jì):the seventies of the 20th century或 the seventies of the twentieth century
(3).表示日期:1949年10月1日:October the first,nineteen forty-nnine(注意日期的縮寫表達(dá)及讀音)
(4).分?jǐn)?shù)的表示:分子用基數(shù)詞,分母用序數(shù)詞,分子大于1時(shí),分母用序數(shù)詞復(fù)數(shù)。
one-fifth Step 3.Practice
課件出示題目,學(xué)生完成相應(yīng)練習(xí)。(通過答題,進(jìn)一步鞏固序數(shù)詞的在實(shí)際中的基本用法。)
Step 4.Prolongation
1.再次通過星期問答“What day is it? It’s Thursday.”導(dǎo)出星期四是感恩節(jié),教育學(xué)生要心懷感恩之心。
Step 5.Homework
1.熟讀序數(shù)詞單詞。
2.掌握序數(shù)詞的變化規(guī)律。
3.抄寫序數(shù)詞,p67表格里的所有序數(shù)詞,每個(gè)單詞抄一次。
