Task Achievement / Task Response: Band 4.5

The response identifies a few relevant elements, including plants and trees, harvesting, processing, microbes, ethanol and transport, so it shows some awareness of the diagram. However, it only minimally reports the process and does not give a clear, factual overview of the full cycle. Several details are inaccurate or unsupported: the diagram does not specify wheat or sugar cane, village land, or supply to other cities and countries. It also omits key stages such as cellulose becoming sugars and the return of carbon dioxide from transport to plant growth. The comments about horticulture and business move away from describing the visual. To improve, summarise the cycle accurately and select its main stages, including the role of carbon dioxide.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the response using “Firstly” and “Secondly,” and the reader can follow a rough movement from plant growth to processing and transport. However, the sequence is not consistently clear, and the ideas are joined in long, difficult sentences. For example, the first section moves from harvesting to crops, factories and sugar without clearly showing the diagram’s stages; the second combines microbes, ethanol, transport and unrelated comments about horticulture. The final business opinion also interrupts the process description. Use separate paragraphs for an overview and the stages, and connect each stage in order with clear references such as “the resulting cellulose” and “the sugars are then converted.”

Lexical Resource: Band 5.0

The response uses some vocabulary relevant to the topic, including “plants and trees,” “harvesting,” “factories,” “microbes,” “ethanol” and “transport.” This gives it a basic range for describing the process. However, word choice and spelling are often inaccurate or imprecise, and some phrases make the meaning difficult to follow, such as “to shape a ethanol form” and “the cycle where mostly be define.” There are also unsupported or unsuitable terms, including “horticulture” and “business term,” which do not help describe the diagram. Aim for precise process vocabulary and check spelling and collocations. For example, use “ethanol is produced” rather than “shape a ethanol form,” and “the process illustrates” rather than “the cycle … define.”

Grammatical Range and Accuracy: Band 4.5

The response attempts to connect several ideas in longer sentences, but control of sentence structure is limited and errors frequently make relationships between ideas unclear. Examples include “then it are many harvesting proccess are be used” and “where added some microbes in it,” where verb forms and sentence construction are faulty. Agreement and articles are also problematic in “a ethanol” and “everyones has.” Punctuation and sentence boundaries need attention: the first section contains many ideas joined together without clear stops, while the final sentence is attached closely to the preceding point. Build accurate simple sentences first, then add a few controlled complex forms, such as “After harvesting, the plants are pre-processed to produce cellulose.”
