1、教師姓名 單位名稱 填寫時(shí)間 學(xué)科 英語 年級(jí)/冊(cè) 七年級(jí)下冊(cè) 教材版本 人教版 課題名稱 第八單元there be 結(jié)構(gòu) 難點(diǎn)名稱 掌握there be 句型be動(dòng)詞變化及句型轉(zhuǎn)換 難點(diǎn)分析 從知識(shí)角度分析為什么難 英語中，there 是引導(dǎo)詞，無詞義。there be 后面的名詞是句子的主語。它像是一種倒裝句，但又非倒裝句，因?yàn)檫@種“倒裝”已成為一種自然的詞序。這種結(jié)構(gòu)中的there本身無詞義，其后的動(dòng)詞be具有“存在”之意，所以是一實(shí)義動(dòng)詞。這個(gè)句型在來理解上有些難。 be 動(dòng)詞 的人稱和數(shù)要與后面的名詞保持一致，并且在多個(gè)主語的情況下，be動(dòng)

2、詞在人稱與數(shù)上采取就近原則。這些是學(xué)生容易出錯(cuò)的地方。 從學(xué)生角度分析為什么難 知識(shí)點(diǎn)句型不易理解和掌握，學(xué)生會(huì)用漢語的思維逐字翻譯。同時(shí)對(duì)可數(shù)名詞單復(fù)數(shù)和不可數(shù)名詞掌握不好也是錯(cuò)題的原因。與be動(dòng)詞之間的關(guān)系缺乏聯(lián)系。對(duì)幾個(gè)基本句型認(rèn)識(shí)不到位，在轉(zhuǎn)換時(shí)不能很快掌握其變型規(guī)律。 難點(diǎn)教學(xué)方法 1.通過觀察所給例句來總結(jié)句型結(jié)構(gòu)和be動(dòng)詞的變化規(guī)律，并用習(xí)題鞏固 2.通過將there be結(jié)構(gòu)的幾個(gè)句型中需變型的部分用不同顏色標(biāo)出來發(fā)現(xiàn)變化規(guī)律，并用習(xí)題鞏固 3.通過口訣來加深記憶 教學(xué)環(huán)節(jié) 教學(xué)過程 導(dǎo)入 Step 1what is“there be ” Look at

3、the picture and make the sentences. 1. “A cat is under the tree.”we can see“There is a cat under the tree.” 2. “Two dogs are under the tree. ”we can see“There are two dogs under the tree.” 概念：“there be ”句型表示某處有某物/某人。 Eg：1.There is a student in the classroom. 2.There are manybooks on the desk

4、. 用法：There be +主語+地點(diǎn)狀語 知識(shí)講解 （難點(diǎn)突破） Step 2 be動(dòng)詞的變化 Look at the sentences and find the rules 1.There is a cat under the tree. 可數(shù)名詞單數(shù) 2.There are two dogs under the tree. 可數(shù)名詞復(fù)數(shù) 用法：There is/are +可數(shù)名詞單數(shù)/可數(shù)名詞復(fù)數(shù)+地點(diǎn)狀語。 3.There is some bread on the desk. 不可數(shù)名詞 用法總結(jié)：There is +可數(shù)名詞單數(shù)/不可數(shù)名詞+地

5、點(diǎn)狀語。 There are +可數(shù)名詞復(fù)數(shù)+地點(diǎn)狀語。 Step 3就近原則 Look at the picture and make the sentences.Then find the rules 1.There is a cat and two dogs under the tree. 2.There are two dogs and a cat under the tree. 就近原則：若句子中有幾個(gè)并列的主語時(shí),be動(dòng)詞的形式要與離其最近的一個(gè)主語在人稱和數(shù)上保持一致。 Step 4 There be 相關(guān)句型轉(zhuǎn)換 There is/are--- 的否定句

6、1.There is a knife in the kitchen. There is not a knife in the kitchen. isn’t 2.There are five apples on the tree. There are not five apples on the tree. aren’t 3.There is some milk in the bottle. There is not any milk in the bottle. 規(guī)則： be詞后面加not, some 變any There be--- 的一般疑問句 1.There
