Teaching Procedures
| Tips
| Step 1 Warming up
| | - Let Ss watch a video about pollution and the environmental protection, then answer the questions:
- How do you feel after watching the video?
- What can we do to heal the world in our daily life?
| | Step 2 Presentation & Practice
| | - Ask Ss to listen to the interview and circle the pollution that have been talked about.
- Ask Ss to listen again and complete the sentences.
- T may want to focus on some words used to talk about the things that are thrown away.
- rubbish (British English) — things that people throw away
- trash / garbage (American English) — things that people throw away
- waste — rubbish and unwanted materials left behind after we have used something, e.g. industrial waste
- litter — things that people have thrown away and left on the ground in public places
- refuse (n. ; pronounced differently from the verb) — a more formal word for “rubbish”
- Answers: 1. more cars 2. pollute 3. are throwing away 4. public places
- Show Ss the listening material, ask Ss to read the conversation sentence by sentence following the recording.
- Ask Ss to role-play the conversation using the information in 2a and 2d.
- For weaker classes, T may want to provide some guidance for the Ss by demonstrating first how the conversation can flow between Jason and Susan. Together with a S more proficient in English, T can role-play the conversation before asking Ss to try it on their own with their partners.
| | Step 3Presentation & Reading
| | - Divide Ss into groups of four. Ask each group to discuss the effective ways to protect the environment and solve the problems of pollution. Then, ask each group to share their answers to the whole class.
After all the groups have shared their answers, T can use the examples from P15-P19 to make a conclusion.
While-reading
- T may wish to invite two volunteers to role-play the given conversation, then ask Ss to identify the ways of solving the environmental problems mentioned in the conversation, without referring to their textbooks. T can ask Ss to write a short paragraph to summarize the problems and the suggested solutions.
- Show the chart on PPT P22 to Ss, ask them to read 2d again and complete the chart.
- Air pollution: Ride a bike, take the bus or subway instead of driving.
- Waste pollution: Bring a bag to go shopping. Don’t take wooden chopsticks or plastic forks when you buy takeaway food. Throw rubbish in the bins.
- Step 1: Ask Ss to think about the questions: What did you learn from the conversation? What other things can we do to protect our environment?
- Step 2: Ask Ss to find their shoulder partners.
- Step 3: Ask Ss to share their answers with their partners.
| | Step 4Language points learning
| | - advantage作名词，其反义词为disadvantage“缺点；不利条件”。take advantage of... 意为“利用……”。
- cost在此处作动词，其过去式和过去分词均为cost。
- cost, spend, take与pay的区别：
- cost的主语是物，宾语是金钱，sth. cost(s) (sb.) some money指“某物花费(某人)多少钱”；
- spend的主语是人，宾语是时间或金钱，sb. spend(s) some time/ money on sth.指“某人花费时间/金钱在某事/物上”，sb. spend(s) some time/ money doing sth.指“某人花费时间/金钱做某事”；
- take常用it作形式主语，宾语是时间，it takes sb. some time to do sth.指“做某事花费某人多长时间”；
- pay主语是人，宾语是金钱，sb. pay(s) some money for sth.指“某人为某物付费”。
| | - Step 5 Exercises& Homework
| | - Do exercises from PPT P28-P29.
- Preview the passage in 3a.
- Do the exercises in students’ book.
| | Teaching Reflection
| This is the second period of the unit. In the unit we talk about pollution and environmental protection. So it is important to get the students to learn words and phrases about the topics in this unit. We will review some structures and tenses and get the students to practice them in listening and speaking. They are “should＋do; used to＋do; have / has＋done; be＋done; be＋doing”. The topic is an important content in our life and students should learn to use the words and structures to talk about and write about it. So much practice should be done in the period and in later periods.
