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 below image reprasent the step cycle a biofuel know as ethanol is made.

Owerall, It contrubted by a 9 major factors cycle process that initialy started by the growth of plants and trees by the help of sunlight and carbon dioxide moreover after a long processing steps it end when microbes added with sugars and give the final product ethanol that use by vechels and there by product carbon dioxide is again use for plants growth.

Firstly, the large trees and sugar cane is harvested by high teck machenries and pre-processed so the give a cellulose then the major step is done in libratries take sugar formula from cellulose.

Secondly, Sugars formula is added by microbes to form a final product called ethanol. Now these ethanol is use as a mobility energy fuel for vechels then again the emergen of fuel creat carbon dioxide that again give energy to growth of plants and trees with the help of sunlight.

In conclugien it is a endless cycle of biofuel which take a long 9 steps with some 4 to 5 high prossesing steps.

AI examiner evaluation

Task Achievement / Task Response: Band 6.0

You identify the diagram as a cycle and give a relevant overview: plants grow using sunlight and carbon dioxide, ethanol is produced, and carbon dioxide from fuel use returns to support plant growth. You also describe several central stages, including harvesting, pre-processing, cellulose, sugars, and the addition of microbes. However, some details are unclear or inaccurate: the diagram shows plants and trees, not specifically sugar cane, and the processing takes place in a factory rather than “libratries.” The account also skips the distinct cellulose-to-processing-to-sugars sequence and does not clearly mention ethanol being used by cars, trucks, and aircraft. The main features are covered, but some stages need more precise and complete explanation.

Coherence and Cohesion: Band 6.0

The response has a recognisable structure: an introduction and overview are followed by two stages of explanation and a concluding sentence. Sequencing words such as “Firstly” and “Secondly” help guide the reader through the process, and the circular nature of the diagram is maintained. However, the progression is not consistently clear. The overview combines many stages in one long sentence, while the first body paragraph moves quickly from harvesting to cellulose and then to sugars without clearly showing the processing stage between them. “Now” and “then again” are somewhat mechanical, and “these ethanol” has an unclear reference. Group the stages in order and use clear links to show how each material changes into the next.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “harvested,” “pre-processed,” “cellulose,” “microbes,” and “final product,” which helps communicate the general sequence. However, the range and precision are limited by repeated or unsuitable expressions such as “step cycle,” “major factors,” and “sugar formula.” Several spelling errors—such as “reprasent,” “vechels,” and “conclugien”—also make the writing less clear and can slow the reader. “High teck machenries” and “libratries” do not accurately describe the diagram’s harvesting equipment and processing factory. Aim for accurate process terms and check spelling; for example, use “stages,” “sugars,” and “factory” where appropriate.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and more extended sentence forms, including a sequence linked with “moreover” and a concluding description of the cycle. The overall meaning is usually recoverable, but some grammatical errors make relationships between stages difficult to follow. For example, “it end when microbes added with sugars” needs a correctly formed verb phrase, while “these ethanol is use” has problems with agreement and passive verb form. Articles and plurals are also inconsistent, as in “a cellulose” and “a endless cycle.” Several long sentences would be clearer if divided or punctuated more carefully. Practise accurate present-simple and passive constructions, such as “microbes are added to the sugars” and “ethanol is used as fuel.”
