人教新目標(biāo)(Go for it)版七年級下冊Unit 8 Is there a post office near here-there be句型微課教案

1、教師姓名單位名稱填寫時間學(xué)科英語年級/冊七年級下冊教材版本人教版課題名稱第八單元there be 結(jié)構(gòu)難點名稱掌握there be 句型be動詞變化及句型轉(zhuǎn)換難點分析從知識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，因為這種“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，其后的動詞be具有“存在”之意，所以是一實義動詞。這個句型在來理解上有些難。be 動詞 的人稱和數(shù)要與后面的名詞保持一致，并且在多個主語的情況下，be動詞在人稱與數(shù)上采取就近原則。這些是學(xué)生容易出錯的地方。從學(xué)生角度分析為什么難

2、知識點句型不易理解和掌握，學(xué)生會用漢語的思維逐字翻譯。同時對可數(shù)名詞單復(fù)數(shù)和不可數(shù)名詞掌握不好也是錯題的原因。與be動詞之間的關(guān)系缺乏聯(lián)系。對幾個基本句型認(rèn)識不到位，在轉(zhuǎn)換時不能很快掌握其變型規(guī)律。難點教學(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 the picture and make the sentences.1. “A cat is under the tr
