IELTS Writing Task 1 question

The diagram below shows the manufacturing process for making sugar from sugar cane.

Summarise the information by selecting and reporting the main features, and make comparisons where relevant.

How sugar is produced from sugar cane

Student answer (Band 6.0)

The given diagram gives information about how sugar is made from sugarcane.

Overall, the process in divided into seven subsequent stages, beginning with the cultivation of sugarcane and ending with the drying and cooling of final sugar product.

First, sugar crop are grown in summer. Next, they are harvested after three years of growth by using machinery or hands. Then the harvested sugar cane is crushed in a machine to obtained juice. Following this, the obtained juice is passed through limestone filter for purification.

In the next step, the purified juice is heated in a closed container where evaporation take place and the purified juice became syrup. In the sixth stage, this syrup is passed from a machine name as centrifuge. In this centrifuge sugar crystals are separated from syrup. In the last step, this sugar crystals are dried and cooled after this cooling process the pure sugar is obtained which is ready to use.

Task Achievement / Task Response: Band 6.0

The response identifies the process as a sequence of seven stages and gives a clear overview from cultivation to drying and cooling, then reports the main steps in order. It also correctly notes the two harvesting methods and the use of a limestone filter, evaporator and centrifuge. However, some details are inaccurate: the cane grows for 12–18 months, not “three years,” and the diagram does not specify that it is grown “in summer.” The final claim that the sugar is “pure” and “ready to use” is also not shown. These inaccuracies and the limited detail about how the centrifuge separates crystals from syrup keep the account from being fully precise.

Coherence and Cohesion: Band 6.5

The response is organised into an introduction, an overview and a chronological description, so the reader can follow the process from growing through to the final stage. Sequencing expressions such as “First,” “Next,” “Following this” and “In the last step” support the progression. This clear overall arrangement is a strength. Some links are less smooth or become repetitive, particularly the final sentence, where “after this cooling process” repeats the preceding idea. The transition into the centrifuge stage could also explain the relationship between syrup and sugar crystals more directly. To strengthen cohesion further, use a wider range of concise links and avoid repeating information already stated.

Lexical Resource: Band 5.5

The response uses relevant process vocabulary, including “cultivation,” “limestone filter,” “evaporation,” “syrup” and “centrifuge,” which helps convey the stages. However, several word choices or forms are inaccurate or awkward: “sugar crop,” “obtained juice,” “machine name as centrifuge” and “pure sugar” do not express the process naturally or precisely. “Subsequent stages” is also less suitable than a straightforward description of the stages. Some repetition of “juice,” “sugar” and “process” limits flexibility. Aim for accurate collocations such as “the cane is crushed to extract juice” and “the centrifuge separates sugar crystals from the remaining syrup.” This would make the vocabulary more precise and natural.

Grammatical Range and Accuracy: Band 5.5

There is a mix of simple and more complex sentence forms, and the stages are generally understandable. However, some grammatical errors recur. The opening overview says “the process in divided,” and “sugar crop are grown” has an agreement error. Verb forms are also inaccurate in “to obtained juice,” “evaporation take place” and “the purified juice became syrup.” Articles and plurals need attention in phrases such as “through limestone filter” and “this sugar crystals.” The final sentence joins several ideas without clear punctuation, making it harder to read. Practise checking subject–verb agreement, passive forms and articles, and divide long sentences into clearer units. These corrections would improve accuracy while preserving the useful range of structures.
