Key:
1- 100 million tons 2. Nuclear and Hydroelectricity
3- 18 million tons
* Elicit the tense and the language which is used in the passage from Ss.
+) Useful Languages:
 - use Simple Past tense.
 - to be under / over / + figure.
 - to make up the largest ...
 - to account for / to take the smallest ...

 a large proportion of ......
 a large percentage of ......
- There was / were + noun / noun phrase.

- Based on the chart in the textbook on page 130, Ss write a description of the trends in energy consumption in the year 2005 in Highland.
- Set the time limited in 5 minutes.
- Move around to give help.
- When Ss have finished , ask them to exchange their writings, comparing and give corrections.
Sample writing:
The total energy consumption in 2005 was over 140 million tons/ under 160 million tons. Nuclear and Hyroelectricity made up the largest amount of this figure. There was nearly as much petroleum used as coal which only made up the smallest proportion of the total about 41 million tons.
* Activity 2:
- Have Ss work in pairs to describe the chart, using similar function of language. Give correction if necessary.
* Activity 3:
- Divide the class into 4 groups.
- Deliver a large piece of paper for each group.
- Ask Ss to compare the amount of energy consumption in the two years 2000 and 2005.
- Set the time limited in 10 minutes.
- Move around to give help if necessary.
- Ask Ss to stick their posters on the board.
 Correction
- Give correction and comments on their writing
 Suggested writing;
 There was an upward trend in the consumption of coal and nuclear & hydroelectricity but there was a sharp decrease in the use of petroleum. The amount of coal used increased by 20 million tons and the consumption of nuclear & hydroelectricity went up dramatically by 54 million tons . However, the amount of petroleum consumed in 2005 fell by 15 million tons.
