1d · Discuss the changes in 1c. How do you think they happened
Li Rui's hometown a lot over the years.
It take half a day to reach the town; now it takes only an hour.
The hills sand, but now they are covered with trees.
The town has built a new hospital and there's even a new supermarket.
That's why Li Rui feels proud and happy about her hometown!
These changes happened because the government built new roads and encouraged people to plant trees. With better traffic and environment, the town also built new public facilities like hospitals and supermarkets for local people. That's why the hometown becomes so nice now!

I think ________ is the worst problem, because ________ .
In my opinion, ________ is more serious than ________ .
I put ________ at No.1, because ________ .
2a Rank the following problems from 1 to 4,with 1 being the worst. Give your reasons.
sandstorms
difficult environment
farmland shortage
lack of technology
1.I think farmland shortage is the worst problem, because we all need food to live. If there is less farmland, we will have less food. Then many people may be hungry or even die.
2. In my opinion, sandstorms is more serious than lack of technology. Because sandstorms can blow away the soil and turn good land into desert. Then we can't grow food at all.
3.I put farmland shortage at No.1, because if people don't have enough food, they can't live. So this problem is the most important. We must solve it first.

and smaller. Then, after one big sandstorm, we decided to do something.
Bob: What did you do
Grandpa: We found a small bush. It had long roots that could hold the soil together. We
began planting it in sandy areas. The government provided support too.
Bob: Wasn’t it difficult to plant so many bushes
Grandpa: Yes, it was. At the beginning, we worked by hand. Later, we had machines to
help. We have planted many bushes and trees since then. There are fewer
sandstorms now and the environment is getting better. It has also improved
our lives. Everyone has become richer and happier.

Unit 1 The Changing World - Section A (1a-2d)
Teaching Objectives
Language ability
Students can name four kinds of change in Li Rui's hometown (transport, medical care, shopping, environment) using the words roads, hospital, supermarket, sand, trees, bushes, machines.
Students can describe a change with three patterns: used to + V, In the past ... Now ..., and has / have become ....
Students can explain a cause with because and that's why, and describe an action without naming the doer with the passive voice (Trees were planted on the hills).
Cultural awareness
Students can recognise road building and tree planting as shared community efforts, and use the feeling words proud, happy, amazed, respectful, thankful.
Students can notice that change has a cost as well as a benefit, and name one thing people may have lost.
Thinking quality
Students can rank four problems (sandstorms, difficult environment, farmland shortage, lack of technology) and give a reason for their order.
Students can build a cause-and-effect chain from problem to action to result to feeling.
Learning ability
Students can use the listening routine: predict, listen for gist, listen for details, then check.
Students can use the self-check list at the end of the lesson to decide what to review.
Key and Difficult Points
Key points
Describe changes with used to ... Now ..., the present perfect and the passive voice.
Get the four areas of change and the action taken in each from the listening texts.
Difficult points
Choosing between the simple past, the present perfect and the passive voice inside one sentence: The hills were covered with sand, but now they have been covered with beautiful trees.
Explaining why and how a change happened, not only what changed.
6. Teaching and Learning Methods
Task-based and communicative teaching; the lesson moves from noticing to using.
Scaffolding: every speaking task is given a sentence frame before students speak.
Listening strategies taught explicitly and reused in 1b, 1c, 2b and 2c.
Pair work for drilling, groups of four for the reporter task.
7. Teaching Procedure - Period 1 (1a-1d), 45 minutes

6 min Change pairs around us Show three contrast pairs: trains (120 km/h to 350 km/h), paying (wallet to QR code), shopping (shops to online). Elicit used to run, runs, have plete each sentence with the class, then say one pair to a partner. Move from the textbook topic to the students' own world. 3, 4, 5

Check half a day to an hour, 40 minutes to 15 minutes, travel far to a new hospital, no good places to a supermarket, sand to beautiful trees. Fill the table individually, check in pairs, then report one row. Practise listening for specific information. 9, 10
5 min Grammar discovery Put the sentences from 1c on the board. Ask what tenses they use to talk about changes. Sort them into simple past, used to, simple present and present perfect. Work in pairs to sort the sentences; say the rule in their own words. Let students discover the rule instead of being told it. 11, 12
6 min 1d Discuss the changes Give the frame: Li Rui's hometown has changed a lot. It used to ... Now ... The hills were covered with ... but now ... Ask how these changes happened. Discuss in pairs and give one cause: new roads, tree planting, government support. Move from describing change to explaining it. 13

8. Teaching Procedure - Period 2 (2a-2d), 45 minutes
Time Step Teacher activity Student activity Purpose Slide
4 min Review Show one before-and-after photo. Ask volunteers to give their 30-second change report from Period 1. Two or three groups report; the class ticks the rubric. Re-activate the language and close the previous task. 14
