1.揭示課題那么,這個運算定律是否對分數(shù)加法也適用呢?現(xiàn)在我們就來研究這個問題。板書課題:整數(shù)加法運算定律推廣到分數(shù)加法。2.研究運算定律對分數(shù)加法的適用性出示式題:提問:上面每組算式的左右兩邊有什么關(guān)系?得數(shù)是否相等?先指名學(xué)生練習(xí),算出得數(shù)后,再引導(dǎo)學(xué)生觀察。提問:這兩組試題有何共同之處?組織學(xué)生開展小組討論,共同概括總結(jié)出他們的共同點,得出規(guī)律性的認識,從而使學(xué)生體會到整數(shù)加法運算定律,對分數(shù)加法同樣適用。通過討論明確:加法的交換律、結(jié)合律中的數(shù),既包括了整數(shù),又包括了小數(shù)和分數(shù)?!驹O(shè)計意圖】通過具體的實踐活動,直觀感知了加法運算定律同樣也適用于分數(shù)加法。這種通過自己實踐得來的東西,學(xué)生理解得更透,掌握得更牢。
教學(xué)目標1.知識目標:(1)學(xué)習(xí)What are you going to be when you grow up?/How are you going to do that?句式。(2)學(xué)會用英語描述有關(guān)職業(yè)的表達法。2.能力目標:(1)能夠談?wù)摓閷崿F(xiàn)理想所做出的打算和安排。(2)能夠談?wù)撐磥碜约号c他人理想的職業(yè)及原因。(3)能用英語描述課余時間的活動安排,最終具備表達綜合信息的能力。3.情感目標:新學(xué)期到來之際,讓他們在學(xué)習(xí)、體育、飲食、特長、讀書等方面制定計劃,教育學(xué)生合理安排自己的課外生活,思考自己的理想職業(yè)及適合自己的職業(yè)。教學(xué)重點、難點本單元的重點為“be going to”表將來,want to be, what,where, when,how引導(dǎo)的特殊疑問句。難點是語言目標的實現(xiàn)。教材分析本單元以I am going to be a basketball player為話題,共設(shè)計了三部分的內(nèi)容:一、Section A該部分有4個模塊。第一模塊圍繞Do you think these jobs are interesting?這一話題展開思維(1a)、聽力(1b)、口語(1c)訓(xùn)練;
“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.

Step 3 (3b)First, tell the students when we talk about our future plans, we often use: I’m+verb+ing When we talk about what we must do, we use have to. Ask the students to fill in the blanks in 3b. The answers are: shopping, go to see, a test, I’m going, my family. Step 4 (3c)Let the students write an e-mail message to a friend. Say why you can’t visit next. Before the exercise, ask the students to give some possible answers and write them on the blackboard. So the students will feel easy to finish the writing exercise. After they finish it, Let them to correct it in groups first. Each group chooses theirs best one to read in front of the whole class.

1. First, ... then, ... next, ... finally, ...首先,……然后,……接著,……最后,……這是英語中表達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通常你會聽到說英語國家的人在說 first, next, then, finally 和后面的內(nèi)容時,他們會做一些停頓。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,謂語動詞用單數(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。
