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 diagram illustrates the process of producing sugar from sugar cane.

Overall, sugar can be manufactured by growing sugar cane in months then harvest it. After that crushing is quite important, then purify it through some filter. The usage of evaporator, centrifugemade the process almost completed. The last step is drying.

To initiate with, the production of sugar is possible only when sugar canes can get the time to grow well which is about 12-18 month. Secondly, crucial thing is harvesting. Harvesting can be done through two methods; wheather it is by cutter or by machines in field. Thirdly, crushing sugar canes and transfer it into juice then purify it carefully so that impurities can be removed.

On the second hand, after the purification evaporator is necessary to make it like syrup through heat. Centrifuge which seperates sugar crystals from syrup. the last step of manufacturing is drying or cooling to make it more appropriate for selling.

Task Achievement / Task Response: Band 6.5

You cover the main stages in the correct general order, and the overview identifies the process from growing and harvesting through to drying. You also include the key growth period and both harvesting methods, while explaining that heating turns the juice into syrup and the centrifuge separates sugar crystals. This gives the response a solid account of the process. Some details are less fully or precisely reported: the final stage is described as “drying or cooling,” whereas the diagram presents drying and cooling together, and the limestone filter is referred to only as “some filter.” The overview also says the process is “almost completed” at the centrifuge without clearly summarising the separation and final output. A more precise overview and fuller naming of the equipment would strengthen coverage further.

Coherence and Cohesion: Band 5.5

The response has a recognisable structure: an introduction and overview are followed by two paragraphs describing the stages. Sequencing expressions such as “To initiate with,” “Secondly,” and “Thirdly” help the reader follow the process, and the broad progression is understandable. However, the organisation is somewhat mechanical and the progression is weakened by awkward or inaccurate links, including “On the second hand,” which does not appropriately introduce the later stages. The overview also compresses several steps into a confusing sentence, particularly “The usage of evaporator, centrifugemade the process almost completed.” Improve cohesion by grouping connected stages clearly, using accurate transitions, and linking each sentence to the previous stage rather than relying mainly on numbered sequencing words.

Lexical Resource: Band 5.5

You use relevant process vocabulary, including “harvesting,” “crushing,” “purification,” “evaporator,” “syrup,” and “sugar crystals,” so the reader can understand the main operations. There are also attempts at more specific language, such as describing the centrifuge’s function. However, the range is limited and several choices or forms are inaccurate or unnatural: “cutter” is not a clear description of the mechanical harvester, “make it more appropriate for selling” is vague, and “usage of evaporator” is an awkward collocation. Spelling errors such as “wheather,” “centrifugemade,” and “seperates” are noticeable. Use precise process terms and check spelling; for example, name the limestone filter and describe the final product as dried and cooled sugar.

Grammatical Range and Accuracy: Band 5.5

You attempt both simple and more complex forms, including a relative clause in “Centrifuge which seperates sugar crystals from syrup” and a purpose clause in “so that impurities can be removed.” The overall meaning is generally recoverable, but some sentence structures are incomplete or faulty. “Centrifuge which separates…” is a fragment, and “The usage of evaporator, centrifugemade the process…” lacks clear grammatical structure. There are also errors in verb forms and agreement, as in “then harvest it,” and in number and articles, as in “12-18 month.” Capitalisation and punctuation need attention, especially the lowercase “the last step” after a full stop. Build complete sentences around each stage and proofread for agreement, articles, plurals, and sentence boundaries.
