Band 6+: You have received a gift from a relative that you cannot use. You want to write a letter to thank them, but also delicately explain the situation. Write a letter to your relative. You should include: - Express your gratitude for the thoughtful gift. - Explain why the gift isn't suitable for you. - Suggest an alternative way they could help you or someone else.

The letter addresses all parts of the task, including thanking the relative, explaining why the gift is unsuitable, and suggesting a solution. The content is relevant and presented in a clear and organized manner. To improve, consider elaborating on the suggested solution to make it more specific and helpful. For example, instead of just asking for the shop's contact, you could suggest exchanging the mattress for a smaller size or a different item altogether. Also, the tone could be slightly warmer to better convey gratitude and maintain a positive relationship with the relative. The letter falls short of the required 150 words.

The letter is generally well-organized and easy to follow. The purpose of each paragraph is clear. However, the transition between explaining why you can't use the mattress and suggesting solutions could be smoother. Consider using phrases that directly link the problem to the proposed solution to enhance the flow.

The vocabulary used is appropriate and conveys the message effectively. To further enhance your lexical resource, try incorporating more varied and specific vocabulary related to the context of gifts and solutions. For example, instead of 'ask for the alternative,' you could use 'explore exchange options' or 'inquire about different models.' Boost vocabulary complexity to elevate the overall score.

The letter demonstrates a good command of grammar with only minor errors. Pay attention to sentence structure and clarity. For instance, the sentence 'In order to solve the problems, I suggest that you should send me the contact of the shop where you bought the gift so that I can ask for the alternative' could be rephrased for better clarity and conciseness. Also, ensure consistent use of articles (a, an, the) where necessary.
