Task Achievement / Task Response: Band 3.0

The response identifies the graph’s subject and gives a basic overview by noting that the USA had the highest proportion and Korea the lowest. These are relevant features, but the account is extremely incomplete: it stops mid-sentence at “while Austr” and does not summarise the other countries or make meaningful comparisons. The USA trend is described as rising steadily, although the graph shows an initial dip from about 45% to 43% before a sustained increase. The response contains 56 words, below the required 150; 10 words copied from the task prompt were excluded from that count. To improve, complete the report and select several key trends and comparisons, including approximate figures where useful.

Coherence and Cohesion: Band 3.5

There is a basic attempt to organise the response: an opening identifies the graph, followed by an overview and then a detail sentence. However, the progression is cut off, and the final sentence ends at “while Austr,” leaving the comparison unfinished. The overview also combines two observations without developing them, so the reader cannot follow a complete account of the data. Linking words such as “Overall” and “In the term of time period” signal stages, but the latter is awkward and does not lead into a clear comparison. Use complete paragraphs and organise the report into an introduction, a concise overview, and grouped details—for example, higher-rate countries and lower-rate countries.

Lexical Resource: Band 4.5

The response uses some relevant task vocabulary, including “line graph,” “proportion,” “rise,” and “steadily,” so its basic meaning is generally understandable. However, the range is narrow and several expressions are imprecise or unnatural, such as “accounted a small proportion” and “In the term of time period.” Country names also need consistent capitalisation: “canada” should be “Canada.” The unfinished “Austr” further limits the evidence available for judging vocabulary. Aim for accurate trend language and natural collocations, such as “accounted for the lowest proportion,” “over the period,” “increased,” and “remained relatively stable.” This would make comparisons clearer and more appropriate for an academic summary.

Grammatical Range and Accuracy: Band 4.5

The response attempts both simple and more extended sentence forms, including “Overall, USA presented the largest proportion and rise for long time period from 1970 to 2020 while, Korea accounted a small proportion.” However, errors in articles, prepositions, and punctuation make these structures less controlled: for example, “the USA,” “over a long period,” and “accounted for a small proportion” would be grammatically appropriate, and the comma before “Korea” is unnecessary. The phrase “USA started from 1970 to 2020” also uses an unsuitable verb pattern for describing a time span. The final sentence is incomplete, so it cannot demonstrate accurate sentence control. Practise complete comparisons using accurate tense and preposition patterns.
