年轻人到较贫穷国家做志愿者

The response identifies kindness as a motivation and describes benefits for both groups. However, it concludes that they enjoy different benefits without clearly deciding which gains more or explaining that their benefits are equal. Some general claims also need fuller support.

The response uses distinct paragraphs and has broadly understandable progression. Some connections are weak, particularly the therefore link from learning qualities outside a classroom to helping people, and the concluding comparison is introduced abruptly through a conversational question.

Vocabulary is adequate for the topic, with expressions such as materialistic world and generous act. Precision is reduced by "who is more beneficial", which asks who provides benefits, and "developed countries" where the paragraph appears to mean the poorer countries receiving help.

Simple and complex sentences communicate the argument clearly, although errors such as "These acts ... constantly reminds" and the noun form "doing works" are noticeable. The embedded clause "how it benefits both parties" is grammatically valid.

The response gives reasons for unpaid work and consistently identifies communities as the main beneficiaries. However, most development shifts from volunteering across wealthy and poorer countries to movement between cities and rural areas within one country, so the specific international situation is only partly addressed.

Paragraphing is logical, with a clear sequence from reasons to benefits and conclusion. However, the repeated contrastive use of However is sometimes weakly motivated, and the malformed opening sentence of the benefits paragraph interrupts the flow of the argument.

Vocabulary is sufficient and sometimes precise for the topic, with attempts at less common items, but there are noticeable imprecisions such as 'prominent cities', 'impact knowledge', and 'seek for job' that reduce precision.

Simple and complex structures convey the main ideas, but errors in articles, capitalisation and clause construction reduce control. In particular, "it is working ... benefits to the youths" combines incompatible structures, and "sought for Job" uses an unnecessary preposition.

Both questions are addressed: personal experience is identified as a motivation, and the response consistently judges that communities benefit more. The opening comparison is awkwardly phrased, while the paragraph on motivation spends much of its space describing community needs rather than explaining the volunteers’ reasons.

Ideas are organised in logical paragraphs with clear progression and appropriate linking devices, although transitions are at times formulaic and the reasoning chain in the second paragraph drifts before returning to the point.

The response uses a sufficient range of topic vocabulary, including voluntary services and living standards. However, awkward comparative phrasing and expressions such as "more civilized" reduce precision; the latter does not clearly describe the specific educational or housing improvements being discussed.

A range of complex structures is used with generally good control. The noun-form error "this helps" is noticeable, although meaning remains clear. The construction "help build" is valid and does not itself indicate a grammatical error.

The response addresses both questions with a clear position and relevant ideas, but the response falls 30 words short of the minimum length and development remains somewhat general.

Paragraphing is logical, progression is clear, and cohesive devices such as 'additionally' and 'in contrast' are used naturally throughout.

Vocabulary is flexible and precise, with terms like 'voluntourism', 'socio-economic challenges', and 'empathetic' used appropriately to convey nuanced meaning.

A wide range of sentence structures is used with good control, including complex constructions and effective contrastive clauses, with only minor slips such as the misplaced space before a comma.

The response addresses both the reasons and the comparative benefit question, develops main ideas with explanation and examples, and states a clear position that both parties benefit.

Ideas progress logically across clear paragraphs with effective cohesive devices, though some linking and transitions are slightly mechanical or formulaic.

There is a good range of topic-related vocabulary used with awareness of style, but occasional unnatural collocations and forced phrases reduce precision.

A variety of complex sentence structures is used with generally good control, and the few minor grammatical slips do not impede communication.

Both parts of the task are addressed with a clear, consistent position that volunteers benefit more, but the response is 30 words below the minimum length and its ideas are developed only at a sufficient rather than extended level.

Paragraphing is logical and cohesive devices such as firstly, secondly, and in contrast are used naturally, producing clear progression throughout the essay.

Vocabulary is flexible and precise, with apt phrases like global inequality, manpower and resources, and transformative, allowing ideas to be conveyed clearly with only routine wording.

A wide range of structures, including complex contrastive and subordinate sentences, is used with good control and only minor, non-impeding lapses.

Both parts of the question are addressed with a clear position and relevant explanations, though the discussion of who benefits relies on assertion and generalisation rather than fully developed support.

Ideas progress logically through clear paragraphs with well-managed linking devices, including effective contrastive transitions, though cohesion within paragraphs is occasionally formulaic.

Vocabulary is flexible and precise, with natural idiomatic phrasing and apt less common items such as ostensibly, pervasive, and concomitant, used with only rare awkwardness.

A wide range of complex structures is used with flexibility and accuracy, including relative clauses and parallel constructions, with errors being rare and non-impeding.
