Summarise the information by selecting and reporting the main features, and make comparisons where relevant.
The formation of rain-shadow deserts
Student answer (Band 4.0)
The map illustrates the process of raining in a rain-shadow desert.
Overall, it can be clearly seen that this is a linear process of raining which has seven stages, which starts with winds come from sea, and ends with dry winds reach inland areas. It is a natural process.
Initially, winds came form the coast subsequently, winds pushed upstream while it collide to the mountains. After that, the moist air cools down and rises. Thereafter,

Task Achievement / Task Response — Band 3.0
The response is significantly under the required word count of 150 words, as it contains only 75 words and is incomplete. Consequently, the task is not fully addressed, and the description of the process is cut off mid-sentence. While the introduction attempts to identify the main features, the lack of development means the reader cannot gain a clear understanding of the process. To improve, you must ensure you complete the description of all stages shown in the diagram and meet the minimum length requirement to allow for a full explanation of the data.
Coherence and Cohesion — Band 4.0
The response shows an attempt at logical sequencing by using transition words such as 'Initially', 'subsequently', and 'thereafter'. However, because the text is incomplete and abruptly ends, the overall progression is severely hindered. Paragraphing is present, but the limited length prevents the development of a coherent structure. To improve, focus on completing your sentences and ensuring that each stage of the process is clearly linked to the next using a variety of cohesive devices, rather than relying on a repetitive list-like structure.
Lexical Resource — Band 4.0
The vocabulary used is basic and somewhat repetitive, such as the frequent use of 'winds' and 'process'. There are also minor errors in word choice, such as 'process of raining' instead of 'process of precipitation' or 'formation of rain'. The range of vocabulary is insufficient to demonstrate the flexibility required for higher bands. To improve, try to incorporate more precise, topic-specific terminology related to geography and meteorology, such as 'moisture-laden', 'orographic lift', or 'arid conditions'.
Grammatical Range and Accuracy — Band 4.0
There are several grammatical errors, including tense inconsistencies ('winds came' vs 'winds pushed') and awkward phrasing ('winds come from sea'). The sentence structures are simple, and the incomplete nature of the text makes it difficult to assess your ability to use complex structures effectively. To improve, focus on maintaining consistent verb tenses when describing a process and work on combining simple sentences into more complex ones using relative clauses or subordinating conjunctions to improve the flow and sophistication of your writing.
