* Key answer:
1. solar energy, air and water
2. atmosphere
3. humans continue
III. Pre- writing: ( 15 mins)
* Activity 1: ( 6 mins) Questions- answers
What sources of energy are mentioned in the chart?

What do the figures 2000, 2005 refer to?
What do the green, red and dark blue columns refer to?
* Key answer: 
Hydroelectricity, petroleum, coal and nuclear
They refer to the consumption of energy
They refer to the years
The green column refers to coal. The red refers to nuclear and hydroelectricity. The dark blue refers to petroleum
* Activity 2: ( 5 mins)
 - be followed by:
- the chart shows/ describes/ presents:..
- as can be seen/ it can be seen that/ according to the chart
- .make up / account for/ contribute the largest / smallest amount of..
* useful language:
The chart shows the past event, so we use the past simple tense.
* Activity 3: ( 4 mins) Fill in the gaps with the information from the chart.

1. 117 2. coal 3. smallest
IV. While- writing: ( 15 mins)
 Continue the description of the trends in energy consumption in the year 2005 in Highland
à Expected answers :
 The chart shows the energy consumption in Highland in 2005. It can be seen, the total energy consumption was 170 million tons. Nuclear & Hydroelectricity made up the largest amount of this figure (75 million tons)
This was followed by the consumption of petroleum (50 million tons). Coal made up the smallest amount of energy consumption (45 million tons) 
V. Post- writing: ( 9 mins)
Describe the chart, using the information from tasks 1 and 2 in your textbook(p.130)
Was the total energy consumption in 2005 higher or lower than it was in 2000?
How many tons were nuclear and hydroelectricity consumed in 2005? Was it higher or lower than it was in 2000?
Was the consumption of coal in 2005 lower or higher than it was in 2000?
Was petroleum consumption in 2005 lower or higher than it was in 2000?
What kinds of energy do people tend to consume more?
* Key answer:
1. The total consumption in 2005 was higher than it was in 2000.
2. 75 tons nuclear and hydroelectricity consumed in 2005. it was higher than it was in 2000.
3. The consumption of coal in 2005 was lower than it was in 2000
4. Petroleum consumption in 2005 was lower than it was in 2000.
5. People tend to consume more nuclear and hydroelectricity than coal and petroleum.
* Suggested paragraph:
 The chart shows the energy consumption in Highland in 2000 and 2005.
 As can be seen, the total energy consumption in 2005 was 170 million tons. So it was higher than it was in 2000 (117 million tons). In 2005, nuclear and hydroelectricity made up the largest amount of this figure (75 million tons). This was followed by the consumption of petroleum (50 million tons). Both of them were higher than they were in 2000. However, coal decreased the amount of the energy consumption (from 57 million tons in 2000 to 50 million tons).
 In conclusion, people tend to consume more nuclear and electricity than coal and petroleum
