To help Ss to learn the importance of helping others and the ways to help others.2. To help Ss to learn about the educational and living conditions of some developing countries and develop their awareness of helping those in need.3. To teach how to use the new words and phrases in the text.Teaching Procedures:Step 1. Leading-in1. Lead Ss to the content of this unit. Teacher may say, “We have all heard about Lei Feng, who was ready to help others and set us an example. We live our own lives. Everybody has his own work to do. Why must we help others?”2. Get some Ss to present their opinions on the question above before the class.Suggested Answer:Nobody can do everything alone, no matter how powerful he is. Nobody never meets with trouble, no matter how well he is going. So everybody needs others’ help. But we cannot alwaysreceive but never give. We must give in return for what we receive. We give help because we have been helped. Since we were born, we have received a lot from the society. So we should return it. We give help today, but we may need help tomorrow. Even if we may not see a person again, by helping him, we can let him know help is necessary and important for those who are in need. By helping each other, people can feel that life is full of warmth and friendliness and is worth living. In a word, to help others is to help oneself.Step 2. Warming Up1. Ask Ss to discuss the following question.In what ways do we help the people around?2. Ask Ss to work in groups of four and one of them to interview the other three. Tell him to ask the questions in Ex1 of Warming Up on P28. Then get one pair to act out their dialogues before the class.3. Divide Ss into four groups and ask them to discuss the following question.Can we call the person who helps others a “volunteer”?Suggested Answer:When one of your parents or friends needs help, you may not be asked to help but you volunteer to help, we don’t say you are a volunteer. A volunteer is a person who helps others in or outside his community or in a foreign country.Step 3. Pre-readingPurpose: To get Ss prepared for the reading text.1.Ask Ss to look at the pictures on P29～P30 and guess what the passage talks about.2.Ask Ss to describe the students and their classrooms in the pictures. After that, let Ss imaginetheir living conditions.3. Lead Ss to the reading text. Teacher may say, “Today we are going to read a letter written by an Australian volunteer, Jo, who taught for two years in Papua New Guinea, a country to the south of Australia.”Step 4. SkimmingPurpose: To help Ss get the general idea of the letter.1.Ask Ss to listen to the tape and try to get the main idea of the text.Suggested Answer:In the letter, the writer wrote about the educational and living conditions in PNG and her experience of visiting a student’s village.2.Play the tape paragraph by paragraph and let Ss read after it. Then ask them to sum up themain idea of each paragraph with only one sentence.Suggested Answer:Para.2: The school is simply built and far away from the students’ homes.Para.3: The educational conditions are very poor.Para.4: I visited a village of one of my student’ and received a warm welcome.Para.5: I stayed with the student’s family and their huts were poorly equipped.Para.6: I had a meal with the student’s family and they cooked in an unusual way.Para.7: I returned from the visit and felt greatly rewarded.Step 5. ScanningPurpose: To help Ss get a deeper understanding of the text..1. Ask Ss to find out the relationship of the people mentioned in the text. Teacher may say, “There are some persons mentioned in the text. Can you name them? Can you find out who they are?” Suggested Answers:Jo — the writer of the letter.Rosemary — the person who Jo is writing to.Tombe — one of the writer’s boy students, whose family Jo visitedJenny — the writer’s fellow workerKiak — Tombe’s motherMukap — Tombe’s father2. Ask Ss to read the text carefully and ask them the following questions. It is better to read them out to Ss than to present them on the blackboard. Encourage Ss to keep the eyes away from the books when they answer the questions.(1)What is the school like?(2)Is the writer popular with her students? How do you know?(3)What is the writer’s difficulty in teaching?(4)Why did the students jump out of the windows?(5)Why does the writer wonder if she is making any difference to her students’ lives?(6)Was the writer warmly welcomed by the villagers? How do you know?(7)Do Mukap and Kiak usually sleep in the same house?(8)Where did the writer and Jenny sleep that night?(9)Why did Tombe throw away the tin can?Suggested Answers:(1)It is made of bamboo and the roofs are made of grass. It is from away from Ss’ homes.(2)Yes. When she gets to school, the students all say hello to her.(3)There is no electricity or water and they have no textbooks. There is no teachingequipment.(4)Because they had never seen such an accident and were frightened.(5)Because most of her students will go back to their villages to work in the field and shethought what they have learnt will be of no use.(6)Yes. Because Tmbe’s mother welcomed her by crying “ieee ieee” and the villager allshook hands with her warmly.(7)No. They sleep in their own huts.(8)They slept on a newly-made platform in Mukap’s hut.(9)Because they think throwing away the tin can is in fact throwing away evil spirits.Step 6. Language point1. Ask Ss to work in pairs and underline and translate the following phrases in the text.hear from, be dying to do sth., up to, adapt to, the other day, before I knew it, come across, make a difference to sb., get to know, shake hands with sb., stick out of, get through, a newly made platform, a couple of, build a fire, leave…to do sth., dry out, dry up, fall into bed2. Lead Ss to deal with some more language points.(1) be dying to do sth (line 2, para1): want very much to do sth, have a strong desire to do sth.I am dying to know what has happened. 我迫切想知道发生了什么。
