Band 5+: After being involved in an accident, you were looked after by a person you did not know before. Write a special thank you letter to express your gratitude. In your letter: • introduce yourself and let him/her know why you are writing • express your appreciation • and offer him/ her to visit your home with his/her family Write at least 150 words. You do NOT need to write any addresses. Begin your letter as follows: Dear ...................,

The letter addresses all three bullet points: it introduces the writer and the reason for writing, expresses gratitude, and offers an invitation. The tone is appropriate and the purpose is clear. However, there are some lapses in accuracy and clarity (e.g., 'cty' instead of 'company', 'stay' instead of 'stayed', 'what do you did' instead of 'what you did'), and the closing 'Best wishes' is slightly informal for a formal letter. To improve, ensure grammatical accuracy and use a more formal closing such as 'Yours sincerely'. The letter falls short of the required 150 words.

The letter is generally easy to follow, with a clear structure: introduction, expression of gratitude, and invitation. However, there are some lapses in coherence, such as the abrupt transition from the introduction to the gratitude section, and the lack of a clear closing paragraph. The use of 'cty' is unclear and may confuse the reader. To improve, consider using more cohesive devices (e.g., 'Furthermore', 'In addition') and ensure each paragraph has a clear central idea. Also, avoid abbreviations and ensure the letter flows smoothly from one point to the next.

The vocabulary used is appropriate for the task, with some good expressions like 'I would like to say a big thank you' and 'I really appreciate'. However, there is limited range and some informal or unclear phrasing, such as 'near the cty' and 'stay with me unlti'. To improve, expand your vocabulary to include more formal and precise terms (e.g., 'assistance', 'accompanied me', 'until my family arrived'). Also, avoid using abbreviations and ensure word choice is accurate and natural. Boost vocabulary complexity to elevate the overall score.

There are several grammatical errors and punctuation issues that affect clarity. For example, 'stay with me unlti' should be 'stayed with me until', 'what do you did' should be 'what you did', and there are missing spaces after periods (e.g., 'confused.You'). Additionally, the letter lacks a variety of sentence structures, relying mostly on simple sentences. To improve, focus on using past tense consistently, correct spelling, and proper punctuation. Also, try to incorporate more complex structures, such as conditional sentences or relative clauses, to demonstrate a wider grammatical range.
