1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語中表達(dá)做某事的步驟的一種說法。如果步驟較多,還可以說:first-next-after that-later on-finally/at last通常你會(huì)聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時(shí),他們會(huì)做一些停頓。這樣就能提前告訴聽者接下來講的是一系列的步驟。這一點(diǎn)在朗讀和聽力中應(yīng)特別注意。2. how many, how much均為疑問詞,同是“多少”,但用法不同。請(qǐng)看:how many修飾可數(shù)名詞復(fù)數(shù),how much修飾不可數(shù)名詞。但在用法上,同學(xué)們常犯如下錯(cuò)誤:1) [誤] How many are there bananas on the table?[正] How many bananas are there on the table?[析] how many, how much 中的many,much是形容詞,常修飾名詞作定語,故后面跟名詞。2) [誤]How much tea are there on the table?[正]How much tea is there on the table?[析] how much修飾不可數(shù)名詞時(shí),謂語動(dòng)詞用單數(shù)。how many與how much的區(qū)別可簡記為:前how many:問“多少”,復(fù)數(shù)名詞后面跑;how much問“多少”,不可數(shù)名詞單數(shù)好。前者答語用基數(shù)詞,后者答語用數(shù)量關(guān)系。
“Go for it!” is based on “Task-Based Language Teaching”. It adheres to “The authenticity principle”, “The form-function principle”, “The task dependency principle” and “The principle of learning by doing”. These principles all accord with the demands of curriculum focus.In and of Grade Seven (II), “Go for it!”, students have learned “The Simple Past Tense”. And it appears again in of Grade Eight (I). teaches students more about how to talk about events in the past. In addition, it gives affirmative and negative statements in the past tense, such as the sentence patterns “Did you see …?” “Were there …?” “Did you go …?” As the first part of Unit 8, Section A opens with a picture presenting the last school trip in the aquarium and continues with several step-by-step practice activities, which are all good for students to master “The Simple Past Tense”. Doing well in Section A will help students integrate the new target language with that in Section B. Thus, they can describe the events in the past freely and foster their own ability of reflecting and practicing. II. Teaching ObjectivesTeaching objective is the beginning and aim of teaching activities. According to the overall goal of the English elementary course--- improve students' synthetic ability of language application, which should be based on the development of students’ “Language knowledge”, “Language skills”, “Character building”, “Learning strategies” and “Cross-cultural awareness”. The teaching objectives are described as follows(I). Knowledge objectivesi. Master the simple past tense of regular and irregular verbsii.

Using the activities we write in 1a to make conversations .For example :What are you doing for vacation ? I’m visiting my uncle . 2. Pairwork .Practice in pairs . 3. 用第三人稱練習(xí)對(duì)話.
[設(shè)計(jì)意圖:鞏固減法的意義,培養(yǎng)學(xué)生初步的思維能力。](2)組織學(xué)生自己先算一算,教師巡視,捕捉學(xué)生學(xué)習(xí)信息,糾正不良學(xué)習(xí)習(xí)慣。[設(shè)計(jì)意圖:通過巡視,及時(shí)捕捉學(xué)生的學(xué)習(xí)信息,發(fā)現(xiàn)問題及時(shí)解決;把培養(yǎng)學(xué)生良好的計(jì)算習(xí)慣、審題習(xí)慣及檢查習(xí)慣落到實(shí)處。](3)組織學(xué)生全班交流計(jì)算方法。組織學(xué)生在全班交流解決計(jì)算“32-2=”的方法,引導(dǎo)學(xué)生理解“32是由3個(gè)十和2個(gè)一組成,從32里去掉2,就剩3個(gè)十,所以32減2等于30”。如果學(xué)生用其他的方法來計(jì)算,只要正確,也要肯定。[設(shè)計(jì)意圖:同前面一樣,鞏固數(shù)的組成,訓(xùn)練每一個(gè)學(xué)生“述說整十?dāng)?shù)加一位數(shù)相應(yīng)減法的計(jì)算過程”,突破難點(diǎn)。]3.加減法對(duì)比組織學(xué)生比較“30+2=32”和“32-2=30”,并說一說有什么發(fā)現(xiàn),使學(xué)生認(rèn)識(shí)到“3個(gè)十和2個(gè)一組成32,所以30加2等于32;反過來,32是由3個(gè)十和2個(gè)一組成,從32里去掉2,就剩3個(gè)十,所以32減2等于30”[設(shè)計(jì)意圖:強(qiáng)化加減法意義的聯(lián)系,培養(yǎng)學(xué)生初步的思維能力。]
四、課堂小結(jié)今天我們一起研究了什么問題?板書課題:求一個(gè)數(shù)比另一個(gè)數(shù)多幾的應(yīng)用題解答這樣的問題,應(yīng)該怎樣進(jìn)行分析?在老師的提問下,學(xué)生回憶分析思路。最后,小結(jié)上課時(shí)男女學(xué)生小旗的情況,得出數(shù)目后問:你能根據(jù)今天學(xué)習(xí)的內(nèi)容提出問題并列式計(jì)算嗎?教學(xué)反思:求一個(gè)數(shù)比另一個(gè)數(shù)多幾的應(yīng)用題,本節(jié)課屬于計(jì)算教學(xué)。傳統(tǒng)的計(jì)算教學(xué)往往只注重算理、單一的算法及技能訓(xùn)練,比較枯燥。依據(jù)新的數(shù)學(xué)課程標(biāo)準(zhǔn),在本節(jié)課的教學(xué)設(shè)計(jì)上,創(chuàng)設(shè)生動(dòng)具體的教學(xué)情境,使學(xué)生在愉悅的情景中學(xué)習(xí)數(shù)學(xué)知識(shí)。鼓勵(lì)學(xué)生獨(dú)立思考、自主探索和合作交流。尊重學(xué)生的個(gè)體差異,滿足多樣化的學(xué)習(xí)需求。 在課堂過程中,還有小部分學(xué)生不能充分地展開自己的思維,得到有效的學(xué)習(xí)效果,讓所有的學(xué)生基本都學(xué)會(huì)如何去展現(xiàn)自己的有效的學(xué)習(xí)方式,這是我的教學(xué)目標(biāo)。
