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 5.5)

The Pictorial representation Illustrates, the process of converting biofuel into ethanol and how it is produced. Overall the plants and trees is the main thing furthermore, add some effort to make ethanol.

To begin with, first step is to grow plants and trees and the absord energy from sunlight and carbon diaoxide for their growth. The farmer harvest the trees and plants. Next step is a pre-processing method after the process cellulose is appears. Furthermore the processing is the next step and add some kind of chemicals in it.

Continuing the process, it forms in sugars. Next prcess is microbes added in it and the last step is Ethanol is ready by all the process we have done. After the all steps Ethnol used in cars, trucks and in aeroplanes and the engine exhale the smoke and the smoke will called the Carbon Dioxide and it will be useful for plants and trees for growing.

Task Achievement / Task Response: Band 5.5

You identify the main subject and describe the broad sequence from plant growth through processing to ethanol use, including the return of carbon dioxide to plants. This gives the reader a basic account of the cycle. However, some details are inaccurate or unsupported: the diagram does not show chemicals being added during processing, and it shows microbes being added after sugars are produced. The overview that plants are “the main thing” and that “some effort” is needed does not clearly summarise the key feature: ethanol production is a cycle in which carbon dioxide released by transport returns to support plant growth. Develop the stages more precisely and avoid adding information not shown in the diagram to make the account more complete and accurate.

Coherence and Cohesion: Band 6.0

The response has a generally understandable order, moving from plant growth to harvesting, processing, ethanol, and its use in transport. Paragraphing also separates the opening from the process description. Sequencing phrases such as “To begin with,” “Next step,” and “Continuing the process” help guide the reader, although their repeated, formulaic use makes the links feel mechanical. Some connections are unclear, particularly “after the process cellulose is appears” and “Next prcess is microbes added in it.” Use clearer links that show the relationship between stages, and organise the account into a concise overview followed by logically grouped stages. This would make the progression easier to follow without relying so heavily on repeated transition phrases.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvest,” “pre-processing,” “cellulose,” “sugars,” and “carbon dioxide,” so the topic is recognisable. However, the range is limited and several choices or combinations are inaccurate or vague, such as “add some effort,” “some kind of chemicals,” and “the engine exhale the smoke.” These expressions do not describe the diagram precisely and can make the reader work to infer your meaning. Spelling errors such as “absord,” “diaoxide,” “prcess,” and “Ethnol” also reduce accuracy. Aim for precise process verbs and standard spelling, and use terms such as “release” or “emit” for carbon dioxide rather than describing it as smoke.

Grammatical Range and Accuracy: Band 4.5

You attempt both simple and linked sentences, and the overall sequence can usually be understood. However, control of basic sentence structures is inconsistent, and several errors affect clarity. For example, “the plants and trees is” has subject–verb disagreement, while “the farmer harvest” needs a plural subject or a different verb form. The construction “after the process cellulose is appears” combines incompatible verb forms, and “Ethanol is ready by all the process we have done” is not grammatically well formed. Articles and sentence boundaries are also unreliable, as in “first step is to grow.” Practise accurate subject–verb agreement and complete clauses first, then build longer sentences with clear links between stages.
