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)

The diagram illustrates how a biofuel called ethanol is produced.

Overall, there are seven steps to made ethanol. These steps is explain one one in the figure. The first is plants and tree growing in the land. Plants and tree make energy this is made sunlight and carbon dioxide.

On other hand, after growing plants then it harvesting with the help of different tools. And next step is pre processing in different machines and it made cellulose. The next step is processing these cellulose pieces sent in to the mills and there machines processing these cellulose to make sugar and after this step in sugar added microbes. These all steps made ethanol.

The ethanol is used in cars and trucks and airplane. The ethanol used in different industry . The cars and trucks fuel exit the carbon dioxide in the air . In this way air quality is pullated and reason of different dieases.

AI examiner evaluation

Task Achievement / Task Response: Band 5.0

You identify the subject and describe several central stages, including harvesting, pre-processing, cellulose, processing, sugars, microbes and ethanol. However, the overview is inaccurate: the diagram does not show seven steps, and it is not simply a linear process. It presents a cycle in which carbon dioxide is absorbed as plants grow and is released when ethanol is used by transport. The response also says plants “make energy,” rather than using sunlight and carbon dioxide to grow, and adds claims about pollution, disease and other industries that are not shown. To improve, give an accurate overview of the cycle and report the transport uses and carbon-dioxide return without adding unsupported effects.

Coherence and Cohesion: Band 5.5

The response has a basic sequence, moving from plant growth through processing to ethanol use, and paragraph breaks separate the introduction, production stages and final use. However, progression is not consistently clear: “On other hand” does not express a relevant contrast, and “These steps is explain one one” does not clearly introduce the sequence. Several stages are crowded into one long sentence, making the relationships between cellulose, processing, sugars and microbes difficult to follow. The final paragraph shifts from the diagram to pollution and disease, weakening the focus. Use a clear overview followed by logically grouped stages, and connect each step with precise sequencing language such as “Next” and “Once the sugars are produced.”

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvesting,” “pre processing,” “cellulose,” “microbes” and “ethanol,” which helps communicate the main subject. However, the range is limited and several choices are inaccurate or unnatural, such as “different tools,” “mills,” “fuel exit the carbon dioxide,” and “air quality is pullated.” Repetition of “step,” “made” and “plants and tree” also reduces precision. Some terms introduce details not supported by the diagram, including “different industry.” Aim to use accurate process collocations and the diagram’s own labels—for example, describe carbon dioxide as being “released” by vehicles and “absorbed” by growing plants. Check spelling and word forms carefully.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and longer sentences, but control is weak and errors occur frequently, sometimes making relationships difficult to understand. Examples include “there are seven steps to made ethanol,” “These steps is explain,” and “after growing plants then it harvesting,” which show problems with infinitives, agreement and verb forms. Articles and plurals are also inconsistent in “plants and tree” and “in sugar added microbes.” Longer constructions, such as the sentence beginning “The next step is processing,” become difficult to follow because clauses are joined without clear grammatical structure. Practise accurate present-simple descriptions of processes, including passive forms such as “the plants are harvested” and “microbes are added,” before extending sentences.
