五、温故知新
人称代词的主格用来表示动作的发出者，在句子中做主语，放在动词的前面。
人称代词的宾格指一个动作作用在什么人物的身上，是动作的承受者，在句子中作宾语，放在动词或介词的后面。
因此，如果一个人称代词要放在动词或介词后面，一定用人称代词的宾格形式。
E.g. I gave him an apple.我给了他一个苹果。
2.牛刀小试
1) like dancing.(We ,Us ,Our ,Ours)
2)Let have a look.(me ,my ,mine ,I )
3) goes to work on foot every day.(He ,Him ,His)

仁爱版初中英语七年级上册Unit2_Topic_1_Section_A_教学设计与反思
Teaching Plan for SectionA,Topic1, Unit2(Project English, Grade Seven)Self-introductionGood morning, ladies and gentlemen. Nice to meet you .I’m very glad to be here sharing my lesson with you. Today I am going to talk about Unit 2 Topic 1 Section A I have a small nose. I prepare to say the lesson from seven parts.Ⅰ、Analysis of the Teaching Material1. Status and function•Unit2 is the real beginning of the whole Junior Middle School English. The content in this unit is not only releated to the students’life , but also interested and colorful. This lesson tells us how todescribe a person and how to talk about possessions. Besideslearning this, students will also learn some words, phrases andexpressions of people's looks and so on. In this lesson, the main job is to understand the simple present tense using “have/has”.I willlead the students to pay attention to the new tense.2、Teaching Aims and Demands(1) Knowledge aimsa. Get the students master the words about parts of the body: nose, eye, head, face, hair, ear, mouth, neckb. Learn the simple present tense with “have/has” and understand some useful sentences:(1)I have a big nose.(2)They have round faces.(3)She has long hair.(4)It has big ears.c. Learn how to describe people’s appearances.(2) Skillful aimsa. Develop the students’ abilities of listening, speaking, reading and writing.b. Train the students’ abilities of communication.(3) Affective aimsa. Develop the students’ habits of paying close attention to the differences between Chinese culture and western culture.b. Strengthen the students’ conception of cooperation.c. Help the students feel the happiness of learning.3. Key points and difficult pointsAccording to the New English Curriculum Criterion and the students’ real situation, I choose the following materials as the key points and the difficult points of this class.(1)Key pointsa. Develop the st udents’ abilities of listening, speaking, reading and writing.b. Learn some information about people’s appearances.(2) Difficult pointsHow to use the simple present tense with “have/has”Part Ⅱ. Analysis of the StudentsThe students in my class are lovely and co-operative. Most of them are interested in English. They have learnt English for nearly three years. And they have learnt some basic skills of listening, speaking, reading and writing. But on one hand, they are eager to show themselves and want to have a try. On the other hand, in the daily life there are few chances for them to speak English and most of them are too shy to speak English in public or are afraid of making mistakes. So I will try my best to create a relaxing environment for them to practice using English.Part Ⅲ. Analysis of Teaching MethodIn this lesson I will mainly use Five Steps Method and Task-Based Language Teaching. I think if I want the students to improve their oral English, I must give them more chances to practice. That is “Learning by doing, learnin g by using”. In this case, by designing tasks according to the New English Curriculum Criterion, I will lead my students to study and cooperate with each other.Part Ⅳ. Analysis of Learning MethodThe main feature of the Task-Based Language Teaching is the students’ participation and creation. So I plan to enable the students to use “self-learning” and “co-operative learning” as their learning methods Thus, the students are required to do as follows:1. Be well prepared for the new lesson, look up some necessary information.2. In the class learning, the students should work actively and finish the tasks efficiently.3. The students should learn to work with others from their bottom of hearts.Part V. Analysis of Teaching ProceduresStep 1 Warming-up and Review(1)Show a table about Jane. Create a proper atmosphere for the new lesson . Then let the students answer the questions according to the table.T: What’s her name?S1: Her name is Jane.T: How old is she?S2: She is twelve.T: Where is she from?S3: She is from Canada.T: What class is she in?S4: She is in Class Four, Grade Seven.T: What’s her telephone number?S5: It’s (010)9267-6929.(2)Let the students look at a picture and review the words: eye, nose, mouth, ear, neck, head, hair.(3) In order to make the students remember the words quickly, I deside to play a game with them. And the name of the game is “Touch your body.”I say “Touch your nose”, the students touch it quickly. I’ll Praise the students with “well done. You are wonderful.Excellent” and so on . Reason: It is necessary for the students to review learned knowledge. Through this activity, the students can be cheered up, too.Step 2 Presentation1. Show some pictures and teach the phrases, such as, “a small nose, a wide mouth, long hair, big eyes, and so on.2. Let the students observe the picture, and try to say:She has long hair. He has a wide mouth.He has short hair. She has big eyes.3. Let the students read 1a after the tape and pay attention to the pronunciation and intonation. At the same time, let the students underline the words and phrases that they don’t understand.4. Read 1a again and complete 1b,check the answers. Encourage the students to get help from their group members.Reason: This step aims to make the students get the general idea of the article.Step 3 Consolidation1.Let the students look at the chart and discuss in groups. Showyourself. They will say: I have a small nose. He has a wide mouth.They have big eyes. She has long hair.2.I’ll let some students come to the front. Other st udents describehim/her using their words. They will feel excited.Reason: The step aims to make the students not only practicetheir speaking ability but also feel the happiness of learning. Step 4 Practice1.Work in groups. Show a picture and let the students writedown her appearance. Let them list as many sentences aspossible in groups.2.I’ll give the students some chances to shoe their passages infront of the students.Reason: Task-based language Teaching Method is used here to develop the students’ ab ility of writing and also their ability of their cooperation will be well trained.Step 5 HomeworkAfter class, I’ll let the Ss Write a passage about Jim’s appearance in the exercise book. I think homework is so important that the Ss should speak English as much as they can in class or after class. It is necessary for the Ss to do some exercises after class to consolidate the knowledge they learned.Blackboard Design：Reason: In this step, I’ll write the important words to help the students understand the present tense with have/has.Reflection about this lesson1. In the teaching process, we should encourage the students to join, observe, practice, think independently and cooperate. Change their thought from “I have to study.” to “I want to study.”2. As teachers, to make our English classrooms shine with vitality, we are laid with heavy burden, and we still have long way to go.Teaching Plan for SectionA,Topic1,Unit2(Project English, Grade Seven)。
