Band 4+: The line graph below shows the average daily water consumption per person in three cities between 2000 and 2020.

The report addresses the main trends and provides data for all three cities, which satisfies the basic requirements of the task. However, there are several issues with clarity and accuracy in the overview. For instance, the overview states City B had the highest consumption in 2020, whereas the data indicates City A (125) and City B (130) are close, but the comparison logic is slightly muddled. To improve, focus on organizing the information more logically - perhaps by grouping cities with similar trends versus those with opposing trends. Additionally, work on grammatical precision and sentence structure to ensure that the relationships between the data points are communicated clearly to the reader. The report falls short of the required 150 words.

The report struggles to maintain a clear flow of information. While there is an attempt to organize the response into an introduction, overview, and body paragraphs, the transitions between ideas are abrupt and often confusing. The use of cohesive devices is limited, and the lack of proper punctuation makes it difficult for the reader to follow the logical progression of the data. To improve, focus on using linking words (e.g., 'In contrast', 'Furthermore', 'Subsequently') and ensure each sentence is a complete, distinct thought.

The vocabulary used is quite limited and repetitive. There are several instances of incorrect word forms and awkward phrasing, such as 'the most city that uses water' or 'fail down'. There is also a lack of variety in describing trends (e.g., instead of just 'increased', use 'rose steadily' or 'climbed'). To improve, work on learning collocations related to data description, such as 'water consumption levels' or 'a significant decrease', and ensure that nouns and verbs are used in their correct forms.

Grammatical errors are frequent and significantly impede communication. There are issues with subject-verb agreement (e.g., 'they was'), tense consistency (mixing present and past tense when describing historical data), and sentence structure. Many sentences are run-on sentences that lack necessary punctuation. To improve, focus on mastering basic sentence structures, the correct use of past tense for historical trends, and the proper use of articles and prepositions.
