區(qū)分賓語從句、定于從句和狀語從句賓語從句和狀語從句,都叫做主從復(fù)合句。賓語從句主要是中考必考的,是初中階段必掌握的從句,賓語從句主要是掌握三要素,所謂賓語從句,就是賓語在主從復(fù)合句當(dāng)中充當(dāng)賓語的一個句子,叫做賓語從句。主句的謂語動詞是及物動詞,后面如果是詞或者是短語的話,是簡單句,如果是句子的話,肯定是賓語從句。I know that he good at English.就是賓語從句,三要素,一要素是要注意連詞,連詞一共學(xué)了三類連詞,一類連詞是that口語當(dāng)中可以省略,就像剛才說的那一句,I hear he is good at English.還有疑問代詞、疑問副詞,how where when,疑問代詞、疑問副詞。還有一類連詞weather是否的意思,不是狀語從句當(dāng)中的如果,這一定要和如果區(qū)分開,這是是否。I don't know if he interested at English。賓語從句要注意if是連詞。第二要素是語序,要用陳述舉語序。比如說你家有幾口人,我們都說How many people are there in you family?但是這是簡單句,一旦說成賓語從句,你可以告訴我你家有幾口人嗎?Could you tell me how many people there are in you family ?

There are four snow globes in the pictures. And what are they?Ss: They are a monster, two polar bears, two penguins and a birthday cake.Write these words on the blackboard: snow globe; monster; polar bear; penguin and birthday cake. Read them to the class and ask students to repeat each one. Make sure students understand each word.Use a computer to show the E-mail message on the screen and read the message to students.Get students to read the e-mail on their own, and then draw lines connecting each snow globe and its description.Correct the answers.AnswersA line should connect each snow globe picture with the words that describe it in the letter.Step Ⅳ 3bThis activity provides writing practice using the target language.First review Activity 2a on Page 47.Then ask students to complete the message according to Activity 2a.Some partial sentences are given to students. Write about one person's collection.When students work, walk around the room checking the progress and offering help as needed.When they finish, ask some students to read their messages to the class.

(一).知識方面: 1.培養(yǎng)學(xué)生能運用過去進行時來描述、談?wù)撨^去某個時間正在發(fā)生的事情或動作的意識和能力,能就過去某個時間正在發(fā)生的動作做出正確的描述。 2.培養(yǎng)學(xué)生的想象力和角色扮演的合作能力。 3.培養(yǎng)學(xué)生講述過去發(fā)生的事情經(jīng)過的能力。能正確運用一般過去時來講述故事。 (二).技能方面: 1.本單元的語言目標(biāo)是Talk about past events and tell a story(談?wù)撨^去的時間和講述一個故事),圍繞這一目標(biāo),要涉及句型: What were you doing when the UFO arrived? ----I was sitting in the barber’s chair. The barber was cutting my hair. 因此必須學(xué)習(xí)standing、studying、cleaning、sleeping、cooking、making、eating、cutting、等表示地點的詞,以便為上述句型提供語言材料。2.學(xué)習(xí)過去進行時的有關(guān)知識。Was/were+現(xiàn)在分詞,是該時態(tài)的表達式。 3.在學(xué)習(xí)過程中,要區(qū)分The boy was walking down the street when the UFO landed.和While the boy was walking down the street, the UFO landed.這兩種由when和while引導(dǎo)的狀語從句的句型結(jié)構(gòu)。注意它們的不同。

教學(xué)要求1. 通過生活中的事例,學(xué)會解決“找次品”這類問題的思想方法。2. 體會解決問題策略的多樣性及運用優(yōu)化的方法解決問題的有效性。3. 感受到數(shù)學(xué)在日常生活中的廣泛應(yīng)用,培養(yǎng)應(yīng)用意識和解決實際問題的能力。學(xué)情分析有化是一種重要的數(shù)學(xué)思想方法,可有效地分析和解決問題。本單元主要以“找次品”這一操作活動為載體,讓學(xué)生通過觀察、猜測、推理的方法感受解決問題策略的多樣性,在此基礎(chǔ)上,通過歸納、推理的方法體會運用優(yōu)化策略解決問題的有效性,感受數(shù)學(xué)的魅力。這些內(nèi)容對五年級的學(xué)生來說有一定的難度,所以應(yīng)讓學(xué)生在具體操作和試驗中感悟、體會,由此使學(xué)生養(yǎng)成勤于思考、勇于探索的精神。教學(xué)重點學(xué)會解決“找次品”這類問題的方法。

因此,本套教材中刪去了“整除”的數(shù)學(xué)化定義,而是借助整除的模式na=b直接引出因數(shù)和倍數(shù)的概念。在本冊教材中,由于允許學(xué)生采用多樣的方法求最大公因數(shù)和最小公倍數(shù),分解質(zhì)因數(shù)也失去了其不可或缺的作用,同時,也是為了減少這一單元的理論概念,教材不再把它作為正式教學(xué)內(nèi)容,而是作為一個補充知識,安排在“你知道嗎?”中進行介紹。由于這部分內(nèi)容較為抽象,很難結(jié)合生活實例或具體情境來進行教學(xué),學(xué)生理解起來有一定的難度。在過去的教學(xué)中,一些教師往往忽視概念的本質(zhì),而是讓學(xué)生死記硬背相關(guān)概念或結(jié)論,學(xué)生無法理清各概念間的前后承接關(guān)系,達不到融會貫通的程度。再加上有些教師在考核時使用一些偏題、難題,導(dǎo)致學(xué)生在學(xué)習(xí)這部分知識時覺得枯燥乏味,體會不到初等數(shù)論的抽象性、嚴(yán)密性和邏輯性,感受不到數(shù)學(xué)的魅力。所以在教學(xué)中應(yīng)注意以下兩點: (1)加強對概念間相互關(guān)系的梳理,引導(dǎo)學(xué)生從本質(zhì)上理解概念,避免死記硬背。(2)由于本單元知識特有的抽象性,教學(xué)時要注意培養(yǎng)學(xué)生的抽象思維能力。

2、揭題:小朋友們,知道嗎?剛才你們的學(xué)習(xí)過程其實就是統(tǒng)計的過程,這節(jié)課我們就一起來研究統(tǒng)計的有關(guān)知識。3、發(fā)統(tǒng)計圖和統(tǒng)計表:根據(jù)你剛才收集的數(shù)據(jù),完成統(tǒng)計圖和統(tǒng)計表。實踐活動(調(diào)查全班小朋友們喜歡的動物)統(tǒng)計表:(學(xué)具卡片)綠孔雀非洲象大熊貓袋鼠梅花鹿河馬統(tǒng)計圖:(學(xué)具卡片)綠孔雀非洲象大熊貓袋鼠梅花鹿河馬4、出示統(tǒng)計圖和統(tǒng)計表。(1)通過小朋友們的統(tǒng)計,你能發(fā)現(xiàn)什么?(2)你可以提出什么問題?三、總結(jié):1、日常生活中有許多事情可以用統(tǒng)計解決,你能說一說嗎?2、談?wù)勥@節(jié)課你的收獲。作業(yè)布置:第二課時、練習(xí)教學(xué)內(nèi)容:完成練習(xí)十七的2——4題。教學(xué)目標(biāo):鞏固本單元所學(xué)的內(nèi)容。教學(xué)過程:一、檢查作業(yè):1、小組互相交流自己調(diào)查的結(jié)果。2、展示幾份。二、練習(xí):練習(xí)十七1、第2題。(1)看圖,明確題意。(2)先用自己喜歡的方法統(tǒng)計。(3)完成統(tǒng)計表及問題。(4)集體訂正。
