IELTS Writing Task 1 question

 

The diagram below shows how a biofuel called ethanol is produced.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

Student answer (Band 5.0)

In the given diagram illustrates that how ethanol is produced by the use of biofuel.

Overall, it is clear that there are seven steps are envolved to make ethanol. starting at the growth of plants and trees with the help of sunlight and used carbon dioxide which are presence in the whole atmosphere. Terminate at the final step to transform in the lorries and trucks after that they can be recycled atmosphere in the form of cardon dioxide.

In the whole procedure minute steps are involved that generate ethanol. In the initial a farmer cut down all the trees and take it for the net procedure it is know as pre-processing. After that by the passage of machine that could be converted into cellulose and take it int labs. In the next action they are converted into sugar molecules than add some microbes in this sugar level after that ethanol is produced.

In the final step ethanol is transfor in the different locations for export. After that all the material are loaded in the vehicles at the emd they could be converted into carbon dioxide again. This process is used continuously repeat to produced gas by the waste material.

Task Achievement / Task Response: Band 5.5

You identify the subject and give a broad sequence from plant growth through processing to ethanol and carbon dioxide, so the response includes relevant information from the diagram. However, several key details are inaccurate or omitted: the diagram shows three transport modes—car, truck and aeroplane—not only lorries and trucks, and it does not say the fuel is exported or that waste material is used. The overview also misstates the process as seven steps and describes carbon dioxide as being recycled in the atmosphere, rather than showing it returning to support plant growth. To strengthen the report, give an accurate overview of the cycle and describe the main stages without adding unsupported details.

Coherence and Cohesion: Band 5.0

The response has separate paragraphs for an overview, the production stages and the final stage, and it uses sequence markers such as “After that,” “In the next action” and “In the final step.” These help the reader recognise that the diagram describes a process. However, progression is not consistently clear: the overview says the process terminates with transport, while the final paragraph returns to the transport stage, and some links between stages are difficult to follow. Repeated “after that” phrasing also makes the sequencing mechanical. Organise the report in the diagram’s order, use one paragraph for the production stages and another for fuel use and the carbon cycle, and make each reference to a stage explicit.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “pre-processing,” “cellulose,” “microbes” and “carbon dioxide,” which helps convey the subject. However, the range is limited and several word choices or collocations make the meaning unclear, such as “take it for the net procedure,” “take it int labs,” “sugar level” and “recycled atmosphere.” There are also spelling and word-form errors, including “envolved,” “cardon” and “transfor.” Choose precise verbs for each stage and use the diagram’s labels where possible—for example, “harvest,” “convert into cellulose,” and “add microbes.” Avoid introducing terms such as “export” or “waste material” when they are not shown.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and longer sentences, but control is uneven and errors frequently affect clarity. For example, “In the given diagram illustrates that how ethanol is produced” combines incompatible sentence patterns, while “there are seven steps are envolved” has an incorrect verb construction. Other problems include “starting at the growth” as a sentence fragment, “which are presence” instead of a correctly formed verb phrase, and “This process is used continuously repeat,” where the verb forms do not fit together. Use straightforward complete sentences first, checking subject–verb agreement, articles and verb forms. Then add a few controlled clauses, such as explaining that carbon dioxide released by vehicles returns to the plants.
