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)

Here we have diagram, ehich shows that how a biofuel called ethanol is produced. It is actually a flow chart about the process of creation of ethnol.

First of all, the trees and plants observe energy, sunlight, and carbon dioxide. Through this the plants and trees grow very easily.

After that, the harvestors cut them and they sent for pre-processing. During the pre-processing workers divide the cellulose from the trees. Furthermore, after this event they have sent to companies for the proper process. During the process of plants and trees in the companies they seperate the sugars, and use them for different purpose. The sugars, who are saperated from plants in companies are much differnt from the chemical sugars, which we use in daily life.

Microbes are also added in them for their betterment.

The process, after all these is called Ethanol, in this process all the material is export to other countries or cities. This exportation can be done by Airplanes, heavy trucks, and also through the cars. The most important thing is that all these things produce Carbon Dioxide. And this process repeated many times.

By repetation of this process, world is working together and every country and city is also connected to eachother.

Task Achievement / Task Response: Band 4.5

You identify the subject as ethanol production and include several relevant stages, from plant growth and harvesting through processing, microbes, transport and carbon dioxide release. However, the account only partially reports the diagram: the overview is unclear, and some details are inaccurate or invented. For example, the diagram shows cellulose being processed into sugars, not workers separating cellulose from trees or sugars being used for different purposes. It also shows ethanol being used by transport, rather than being exported to other countries or cities. The final claim that countries and cities are connected is not supported by the visual. To strengthen the response, give a concise overview of the cycle and describe the stages and carbon-dioxide return accurately.

Coherence and Cohesion: Band 5.0

The response has a basic sequence, signalled by phrases such as “First of all,” “After that,” and “Furthermore,” so the reader can follow some of the process. However, progression becomes unclear when the description shifts from processing to sugar use, exportation and a general statement about countries being connected. Several sentences repeat or loosely refer to earlier information, such as “after this event” and “all these things,” making the links between stages imprecise. Paragraphing is also limited, with most stages presented in one continuous block. Organise the report into a brief introduction and overview, followed by clearly grouped stages, and use references that identify the material or process being discussed.

Lexical Resource: Band 5.0

You use some relevant process vocabulary, including “pre-processing,” “cellulose,” “microbes,” and “carbon dioxide,” which helps communicate the topic. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the meaning difficult to follow. “Observe energy” is not an appropriate way to describe plants using sunlight, while “seperate the sugars” misrepresents the stage and uses an incorrect spelling. “For their betterment” and “exportation” are also unnatural in this context. Aim for precise process language such as “absorb,” “convert,” and “release,” and avoid adding claims that require vocabulary for ideas absent from the diagram. Check spelling and choose words that describe the depicted stages directly.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and longer sentences, including a sequence of clauses linked with “After that” and “Furthermore.” However, the range is limited, and errors occur frequently in sentence structure, verb forms, articles and agreement. For example, “shows that how” has an unnecessary conjunction, “they sent for pre-processing” lacks a suitable passive form, and “the process … is called Ethanol” does not form a clear grammatical description. The sentence beginning “The sugars, who are saperated” also uses an unsuitable relative pronoun and has faulty agreement. These problems sometimes make relationships between stages hard to understand. Practise accurate passive constructions for process descriptions and use shorter, controlled sentences before combining stages.
