Unit 2 Is this your pencil?.Ø 知識經(jīng)緯第2單元教學內(nèi)容的核心是 “確認物品”,也就是通過學習物品的單詞，對物品的所屬進行回答；學會寫尋物啟事和失物招領(lǐng)。類別語言知識點語音元音字母E在重讀開音節(jié)、閉音節(jié)中相應的發(fā)音以及拼讀規(guī)則E /ei/ E he me E pen set ten重點詞匯重點短語This, pencil, pen, book, eraser, ruler, case, backpack, sharpener, dictionary, that, no, not, yes, sorry, thank, OK, in, English, how, do, spell, baseball, watch, computer, key, notebook, ring, call, at, lost and found, please重點句型交際用語Is this your pencil? Yes, it is. /No, it isntWhats this in English? Its a pen. How do you spell it? P-E-N.Excuse me, Sonia. Is this your pencil? Yes, thank you. And that is my pencil.語法1. 一般疑問句的問與答。2冠詞的初步用法。探索與實踐學會寫尋物啟事和失物招領(lǐng)啟事。Ø 熱點聚焦1 Is that your backpack? No, it isnt. Its his backpack. 那是你的背包嗎？不，不是的。是他的背包。This (這個)， that(那個)他們是指示代詞，主要用來指示或表示人或事物的代詞。單數(shù)復數(shù)近指this這個these這些遠指that 那個those 那些that /those this/these在回答this 和that 作主語的疑問句時，要用it代替this或that, 如：-Is this your note book? 這是你的筆記本嗎？-Yes, it is. 是的。-Whats that? 那是什么？-Its a ring. 是只戒指。2 Excuse me, Sonia. Is this your ruler? Yes, thank you.請問，Sonia，這是你的尺嗎？是的，謝謝。 “Excuse”一詞主要意思是“原諒”。在交際中，“Excuse me”的主要功能是提醒注意，當說話人想問問題、征求允許、問路、糾正對方的某種行為等必須打擾對方時，均可有它開頭。它和sorry的用法有較大的區(qū)別：sorry多用于事后道歉的情景中。 “Excuse me.” 在譯成漢語時有各種靈活的說法，如“勞駕”“對不起”“請問”“打擾一下”，等等。3How do you spell it? P-E-N. 它是怎么拼寫的？這句話和spell it, please, 所達到的交際目的是一樣的，但是，這句話中的how意思是“如何”“怎么”。我們也可以這樣表達：How to spell it? 再比較：How are you?中的how, 那是表示詢問身體狀況。4And that is my pencil-case. 而那才是我的鉛筆盒。承接下句中，我們用and 進行連接，使句子過渡自然。5Please call Mary. 請打電話給Mary.Please 是禮貌用語，表示：“請”，常用于請求或邀請別人做某事的情景中。Please 可以放在句首，也可放在句尾。放在句尾時要用逗號與前面的內(nèi)容隔開。如：Please sit down.= Sit down, please.Ø 思維廣角1所謂確認事物，實際上都的大家所熟悉的身邊的學習和生活用品，在學習過程中容易犯“明知故問”的毛病，這樣就失去了語言交際的功能。那么，怎樣才能體現(xiàn)出語言的交際功能呢？這就要我們?nèi)ビ谩?）猜物?？梢詫⑽锲贩旁诓煌该鞯陌?，允許同伴觸摸，然后問: “Whats this? Is this a ?” 2）多向猜測。畫出幾何圖形，它既可成物品A，也可成物品B；邊畫邊問Whats this? Is this a ? 引導對方說出自己的想象物，添加筆畫，再繼續(xù)圖形。2_. Is this his pencil-box? Yes, it is. A. Sorry B. Excuse C. Excuse meKey: C解析：在要打擾別人之前，應該說excuse me.3How do you spell the word? _. A. Yes, you can B. Sorry, I cant C. No, you cant D. Sorry, I canKey: B解析：上句問句是特殊疑問句，不能用yes/no來回答，如果拼寫，就直接用字母拼寫；如果不能，就先表示歉意，然后說I cant表示自己不會拼寫。所以選B。4Whats that in English? _ a pencil sharpener. A. This is B. Thats C. He is D. ItsKey: D解析：回答“Whats this /that?”常用“Its /It is ”句型，用it來代替上文中的this或that.所以答案是D.5Excuse me, is that _ eraser? No, its _ pencil sharpener. A. a, an B. an, an C. an, a D. a, a Key: C解析：a, an這兩個詞意思一樣都表示“一”，不強調(diào)“一”這個數(shù)量，強調(diào)的是類別。A 用在一輔音音素開頭的單數(shù)可數(shù)名詞前，而an 則用在一元音音素開頭的單數(shù)可數(shù)名詞前。上句中eraser以元音音素開頭，須加an, pencil 以輔音音素開頭，須加a, 所以答案選擇C。Ø 課外拓展1英語的單詞雖然難學，但它本身卻有規(guī)律可循。發(fā)現(xiàn)、掌握其中的規(guī)律，是學習單詞的有效方法，可以學一得十，觸類旁通。從構(gòu)詞法來講，單詞的核心是詞根，前后綴的含義有一定的規(guī)律可循。如：這單元學的sharpener，詞根是sharp(尖的)，從sharp到sharpener的演變過程是這樣的： sharp (鋒利的adj) sharpen（削尖v.） sharpener（卷筆刀n.）又如：short (短的adj) shorten （使縮短v.）read(讀，朗讀v.) reader （讀者n.）2Lost and Found:失物招領(lǐng)美國許多公共場所或公園都設有失物招領(lǐng)處（Lost and Found Office）,失主可以直接與之聯(lián)系。« 自我評估 «I. 聽Unit2 1b,回答下列問題。 1Is this ruler the boys?
