Writing Task 1
You should spend about 20 minutes on this task.
The Diagram below shows how geothermal energy is used to produce electricity.
Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
Write at least 150 words.
Sample Answer
The given diagram shows how electricity is produced by geothermal energy. There are five main steps in this process. First, in a big box connected underground, cold water is collected in order to be pumped down about 4.5 kilo meters.
After that, water is heated passing through hot racks called geothermal zone and it is sent up with pump up in order to be condensed in a big container. At this point, water is in a gas state that is called water vapors and it is sent to turbine which rotates the turbine to generate the electricity with the help of the generator which is the final step of the process chart. Finally energy is translated to a energy tower.
In summary, the geothermal power plant is used to create energy in some steps: heating cold water by a geothermal zone and condensing it in order to put it in a generator turbine which produces the electrical energy to be used.

This is an answer to achieve a BAND 6.5 score. Here is the examiner’s comment:
The candidate has provided a clear introduction and an overview of the key stages of the process. Each stage is identified and described, although there are some minor errors in the reporting of stage 5. There is a room of expansion of the description of each stage, which could help to achieve a higher score. There is a clear overall progression, which each stage being signaled by appropriate markers. These markers are adequate, but a higher score might be achieved by varying their position in each sentence, rather than always placing them at the beginning. The range of vocabulary is adequate for the task and there are attempts to be used more variety here, though there are some examples of errors in word choice in word formation. There is a mix of simple and complex sentence forms, including accurate use of passive forms. There are some errors, but otherwise the level of accuracy is good. The same level of accuracy, over a wider range of sentence forms, would increase the score on Grammatical Range and Accuracy.
SAMPLE ANSWER 2
The graph shows how power is created by geothermal vitality. There are five general strides in this procedure. To start with, in a major box associated underground, cool water is amassed so as to be siphoned down about 4.5 kilo meters.
From that point onward, water is warmed going through hot racks called geothermal zone and it is siphoned up so as to be consolidated in a major compartment. Now, water is in a gas state and it is sent to turbine which pivots the turbine to create the power with the assistance of the generator which is the last advance of the procedure graph. At last vitality is meant a vitality tower.
In outline, the geothermal force plant is utilized to make vitality in certain means: warming virus water by a geothermal zone and gathering it so as to place it in a generator turbine which creates the vitality to be utilized.

This is an answer to achieve a BAND 6.5 score. Here is the examiner’s comment:
There is a blend of basic and complex sentence structures, including precise utilization of latent structures. There are a few mistakes, however in any case the degree of exactness is acceptable. A similar degree of precision, over a more extensive scope of sentence structures, would build the score on Grammatical Range and Accuracy.
SAMPLE ANSWER 3
The chart shows how electricity is made by geothermal imperative. There are five general walks in this methodology. To begin with, in a significant box related underground, cool water is amassed in order to be directed down about 4.5 kilo meters.
Starting there ahead, water is warmed experiencing hot racks called geothermal zone and it is directed up in order to be united in a significant compartment. Presently, water is in a gas state and it is sent to turbine which turns the turbine to make the force with the help of the generator which is the last development of the technique diagram. Finally essentialness is implied an imperative tower.
In layout, the geothermal power plant is used to make essential in specific methods: warming infection water by a geothermal zone and assembling it in order to put it in a generator turbine which makes the imperative to be used.
SAMPLE ANSWER 4
The graph shows how power is made by geothermal criticalness. There are five general strolls in this strategy. In the first place, in a critical box related underground, cool water is amassed so as to be coordinated down about 4.5 kilo meters.
Beginning there ahead, water is warmed encountering hot racks called geothermal zone and it is guided up so as to be joined in a critical compartment. By and by, water is in a gas state and it is sent to turbine which turns the turbine to make the power with the assistance of the generator which is the last improvement of the method outline. At long last centrality is inferred a noteworthiness tower.
In format, the geothermal force plant is utilized to make centrality in explicit techniques: warming contamination water by a geothermal zone and collecting it so as to place it in a generator turbine which makes the noteworthiness to be utilized.
SAMPLE ANSWER 5
The diagram shows how power is made by geothermal criticalness. There are five general walks around this procedure. In any case, in a basic box related underground, cool water is amassed in order to be facilitated down about 4.5 kilo meters.
Starting there ahead, water is warmed experiencing hot racks called geothermal zone and it is guided up in order to be participated in a basic compartment. Before long, water is in a gas state and it is sent to turbine which turns the turbine to make the force with the help of the generator which is the last improvement of the technique layout. Finally centrality is construed a significance tower.
In design, the geothermal power plant is used to make centrality in express procedures: warming pollution water by a geothermal zone and gathering it in order to put it in a generator turbine which makes the significance to be used.
