筹办大学毕业十周年同学聚会

The letter covers all three bullet points with a clear celebratory event, reasons for it, and a request for help with dietary arrangements, though the greeting to a group rather than one named friend and some loosely relevant details slightly reduce precision of purpose.

Ideas progress in a broadly logical order with linking phrases such as 'Furthermore' and 'Moving further', but some transitions are mechanical and relationships between sentences are occasionally unclear.

Vocabulary is adequate for the informal purpose and shows some attempted range, yet noticeable errors in word choice and spelling such as 'soul purpose' and 'bachleour' reduce precision.

A mix of simple and complex structures is attempted, but frequent errors in verb forms and agreement, such as 'I going to married' and 'it been so long', mean accuracy is limited and meaning is strained at times.

The letter covers all three bullet points from the prompt, including the cafe or banquet hall event, the reason of recalling college memories, and the specific help needed to reach two friends, using an appropriately warm and friendly register.

Ideas are logically organised into greeting, purpose, explanation, and request, with workable linking devices such as 'Another reason' and 'Along with that', though some connections feel slightly mechanical.

Vocabulary is adequate and natural for an informal letter but somewhat limited in range, with imprecise collocations such as 'I am writing this letter to organise a get-together' phrased awkwardly and 'doing good' for 'doing well'.

A reasonable variety of sentence structures is used with generally accurate tenses, but errors such as the misplaced relative clause 'which was very famous' and inconsistent comma use show imperfect control.

All three bullet points are directly and fully addressed, with a suitable friendly register, clear purpose, and relevant developed detail such as the venue, dinner, music, and slideshow.

Ideas progress logically across well-organised paragraphs with a clear opening, purpose, justification, request for help, and closing, supported by mostly effective cohesive devices.

Vocabulary is natural and appropriately informal with good collocations like 'relaxed and enjoyable setting' and 'managing the guest list', though it relies on some predictable, safe phrasing.

Grammatical range is good, using varied complex structures and accurate modals and tenses, with only rare, minor slips that do not affect communication.

The letter covers all three bullets with clear, relevant detail: a reunion weekend with a guesthouse and Saturday dinner, the reason that friends are scattered and rarely meet, and a specific request to collect contact details and confirm dates, all in an appropriately friendly tone.

Ideas progress logically from plan to rationale to request, with smooth paragraphing and cohesive devices such as 'My plan is', 'Here is where I need you' and a closing question that ties the letter together.

Vocabulary is precise and idiomatic for an informal letter, with natural phrasing like 'turning an idea over', 'takes large groups', 'slip past' and 'pull together', and there is no awkward or inaccurate usage.

Grammar is flexible and accurate throughout, using varied structures such as conditionals, semicolon-linked clauses and modal requests, with clear control of the informal letter form.
