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 depicts about the process of making Biofuel called ethonol there are several steps in this production it consist of various steps such as harvesting, pre-processing, cellulose and processing.Overall, this diagram discribes about the formation of ethanol through various process and it also explains about the different stages or forms in which ethanol is us used.

Althrough, ethanol is firstly grown in the plantation fields it goes through several processes then it gets harvested ones it get harvested its seeds get seperated from the leaves of the plant then it gets converted into cellulose by ,some lab experiment then the processing of the ethanol is done is laboratary by performing some actions in order to create ethanol.

On the other hand, ethanol is usaully made up of sugar tiny molecules which gets released into cars, truks, and aeroplane ect.Ethanal is considerd an alternative of petrol to reduce the enviormental pollution caused by petrol ethanol creates less pollution inv the enviorment but it damages the internal structure of the vehicles.

In conclusion, i strongly believe that Ethanols are eco-friendly but they are harmful for the vehicles, vehicles can't reley completely on ethanol as an alternative of petrol so its important to look the pros and cons of the ethanol.

Task Achievement / Task Response: Band 4.5

You identify the subject as ethanol production and mention several relevant stages, including harvesting, pre-processing and processing. However, the account only partially describes the diagram and includes important inaccuracies or unsupported details. For example, the diagram shows plants and trees growing with sunlight and carbon dioxide; ethanol is not itself “grown in the plantation fields.” It does not show seeds being separated from leaves, laboratory experiments, or claims about pollution and vehicle damage. The overview also refers to ethanol’s “different stages or forms,” rather than clearly summarising the production cycle and the return of carbon dioxide to the plants. Focus on the stages shown, in their correct order, and avoid adding outside claims.

Coherence and Cohesion: Band 5.0

The response has an opening, an overview, and further paragraphs, so there is some attempt to organise the information. The stages are also introduced in a broadly process-focused way. However, progression is difficult to follow because the sequence is not consistently clear, and the paragraph beginning “On the other hand” shifts from production to unsupported claims about fuel and vehicle effects. Linking phrases such as “Overall,” “Although,” and “In conclusion” are used, but some do not express the relationship between the ideas that follow. For a clearer account, group the growing and processing stages together, then describe ethanol use and the carbon-dioxide cycle, using simple sequence markers such as “next” and “finally.”

Lexical Resource: Band 5.0

You use some task-related vocabulary, including “harvesting,” “pre-processing,” “cellulose,” and “processing,” which helps identify parts of the diagram. However, the range is limited and several word choices or collocations are inaccurate, sometimes making the process unclear. For instance, “ethanol is firstly grown” confuses the fuel with the plants used to produce it, while “some lab experiment” is not supported by the diagram. There are also noticeable spelling errors, including “ethonol,” “discribes,” “seperated,” and “enviorment.” Use precise process vocabulary and check spelling carefully. Alternatives such as “is produced from plant material” and “is converted into sugars” would describe the diagram more accurately.

Grammatical Range and Accuracy: Band 5.0

You attempt both simple and longer sentences, including a sentence linking harvesting, separation and conversion. However, complex sentences are often faulty, and errors in sentence structure, verb forms, agreement and punctuation frequently make the account harder to understand. For example, “it consist of various steps” has an agreement error, and “then it gets harvested ones it get harvested” repeats the idea with inconsistent verb forms. The opening also runs several clauses together without clear punctuation, while “ethanol is usaully made up of sugar tiny molecules which gets released” has problems with clause structure and agreement. Practise writing shorter, complete sentences first, then combine stages with accurate connectors and consistent present-tense verbs.
