The essay has a clear structure with an introduction, body, and conclusion. However, the body of the letter is not organized effectively, leading to some confusion. The use of cohesive devices is inconsistent, and the letter lacks smooth transitions between ideas. The repetition of the same idea disrupts the flow of the letter, making it less coherent. The letter would benefit from better paragraphing and clearer expression of ideas.

Suggestions

• Use a variety of cohesive devices to improve the flow of your writing.
• Consider reorganizing the body of the letter to present your ideas more clearly and effectively.

The letter uses basic vocabulary and expressions, but there are several instances of awkward and unclear phrasing. The repetition of the word “absolutely important” is noticeable and should be varied. The choice of words in some places is awkward and does not fit the context. The letter would benefit from a more varied and precise vocabulary.

The letter contains several grammatical errors that affect clarity and readability. There are errors in verb tense, preposition use, and sentence structure. Some sentences are incomplete or awkwardly phrased, making it difficult to understand the intended meaning. The letter would benefit from a thorough review and revision for grammatical accuracy.

The letter addresses the task and provides relevant details, but it could be more concise and focused. The writer expresses an apology for not returning the book and explains the reasons for the delay. However, the letter is repetitive and could be more concise. The writer mentions asking for the book in three or four days, but this timeframe is unclear and could be more precise. The letter ends abruptly without a proper closing statement, which would have provided a more satisfactory conclusion.

Suggestions

• Try to be more concise and focused in your writing to address the task more effectively.
• Provide a proper closing statement to conclude your letter.
