IELTS Writing Task 1 question

The diagram below shows how one type of desert, known as a rain-shadow desert, is formed.

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

The formation of rain-shadow deserts

Student answer (Band 4.5)

The given process diagram elucidates the mass manufacturing of Rain shadow desert . This process is a joint venture of humans and machines which work together for a single final product . Overall it can be seen that mass production of rain shadow desert is caried out by following seven distinctive steps . Additionally the process starts from winds approach coast by sea and end by Dry winds reach inland areas . Futhermore all steps are very important and are connected with each other . Talking about intial steps first step is winds approach coast wich is following by winds pushed upwards then Moist rises and cools , and clouds from , Rain fall , Dry air continues over mountain , and Dry winds reach inland areas . All these process complete almost half of the total proceduce . Pouring these final steps are very critical to the finished product .

Task Achievement / Task Response: Band 4.0

The response identifies that the diagram has seven stages and gives the broad sequence from winds approaching the coast to dry winds reaching inland areas. However, it only minimally reports the process and includes a major misinterpretation: describing it as “mass manufacturing” and a “joint venture of humans and machines” is unsupported, since the diagram shows a natural weather process. Several stages are listed, but their relationships and causes are not explained clearly; for example, the account does not explain that moist air rises and cools, producing clouds and rain on the windward side, before dry air crosses the mountains and creates a rain-shadow desert inland. Focus on accurately describing the natural process and include a clear overview of its key cause and outcome.

Coherence and Cohesion: Band 4.5

There is a basic attempt to organise the response with an opening, an overview, and a sequence of stages. The use of “Overall,” “Additionally,” and “then” signals some relationships, and the stages are mostly presented in the correct order. However, progression is weak because the response repeats general claims such as “all steps are very important” rather than explaining how one stage leads to the next. The final sentence about “Pouring these final steps” is unclear and does not provide a meaningful conclusion. Paragraphing and clearer links between the stages would help the reader follow the process; for instance, connect rainfall on the windward side to the dry air continuing over the mountain and reaching inland.

Lexical Resource: Band 5.0

The response uses some task-related vocabulary, including “coast,” “moist,” “clouds,” “rain,” and “dry winds,” and attempts more formal wording such as “elucidates” and “distinctive.” However, the range is limited and several choices are inaccurate or unnatural for this diagram. “Mass manufacturing,” “joint venture,” and “finished product” wrongly suggest a human production process, while “mass production of rain shadow desert” repeats that misunderstanding. There are also noticeable spelling errors, including “caried,” “Futhermore,” and “intial,” and inconsistent forms such as “Rain fall.” Use precise process vocabulary and check spelling; terms such as “formation,” “precipitation,” “windward,” and “leeward” would better describe the information shown.

Grammatical Range and Accuracy: Band 5.0

The response attempts a few longer structures, including “Overall it can be seen that…” and “which work together…,” but most sentences rely on simple statements or lists, so the range is limited. Errors are frequent and sometimes make the meaning difficult to follow. For example, “winds approach coast by sea and end by Dry winds reach inland areas” has faulty sentence structure, and “Moist rises and cools” omits the noun “air.” The sequence “clouds from, Rain fall” also lacks a clear grammatical connection between stages. Capitalisation and punctuation are inconsistent, with spaces before full stops and unnecessary capitals. Practise complete sentences with accurate subjects and verbs, such as “As moist air rises, it cools and clouds form.”
