使用手机应用付款的优势与劣势

The response presents a clear position that advantages outweigh disadvantages and develops both sides with relevant examples. However, it does not explain explicitly why convenience outweighs the potential harm from fraud, and the conclusion introduces security without developing that benefit.

Progression is logical across clear paragraphs with generally appropriate linking devices, although 'On the contrary' is misused where a contrastive adverbial like 'on the other hand' is needed, and some cohesion relies on repetition.

Vocabulary is sufficiently flexible and precise for the topic, with natural collocations such as 'phishing email', 'unauthorized transactions' and 'hassle-free transaction', with only occasional vague phrasing like 'provides benefits for people'.

A wide range of complex structures is used with strong control, including conditionals, relative clauses and participle clauses. Errors are rare and do not impede meaning; the repeated “leading to” construction is grammatical, although it offers less syntactic variety.

The response discusses relevant advantages and disadvantages and states a clear position in the introduction. Examples support both sides, but some benefits remain briefly listed, and the argument does not explain sufficiently why the advantages outweigh the risks.

Ideas are logically organised into clear paragraphs with effective use of cohesive devices and examples, showing consistent progression throughout.

The response uses a useful range of topic vocabulary, including digital wallets, cybercrime and network connectivity. Some choices lack precision, particularly audit feature and take advantage of people’s money.

The response uses complex structures with generally good control, including relative clauses and passive constructions. The unclear singular pronoun in Due to its accessibility and ease is a noticeable local weakness.

The response addresses the question directly with a clear position, relevant reasons and examples, though the advantage side is somewhat briefly developed and the conclusion introduces an unsupported point about system failures.

Ideas are logically organised with clear paragraphing and a range of cohesive devices used naturally, despite slightly uneven paragraph balance.

Vocabulary is sufficiently flexible and precise, with natural use of topic-related terms such as encryption, digital divide, and inequitable.

Complex structures are generally well controlled, including relative clauses and passive constructions. Naming the customer in the QR-code example would make the agent of scanning and tapping more explicit.

The response addresses all parts of the task with a clear, consistent position that the advantages outweigh the disadvantages, supported by relevant explanation and examples, though some ideas are developed in a limited or slightly generic way.

The essay is logically organised with clear paragraphing and a range of cohesive devices used naturally, although progression within paragraphs is occasionally loose and the final remedy in the conclusion feels appended.

There is a sufficient range of vocabulary for the topic, including “biometric authentication” and “fraud”, but imprecise wording such as “paid apps” for payment apps and “without any financial means” for an inability to pay by phone reduces precision.

A variety of complex structures is used with good flexibility, including relative clauses and conditionals, and errors are minor and infrequent, generally not impeding communication.

The response addresses all parts of the task with a clear opinion and extended, relevant support, though examples remain general and the conclusion is slightly hedged.

Ideas progress logically across clear paragraphs with a range of cohesive devices used mostly naturally, though some linking is mechanical.

Vocabulary is flexible and topic-appropriate, with occasional imprecision: “issuers’ smartphones” misidentifies the people using the apps, and “mobile phone banking” narrows the question’s broader focus on payment apps.

A variety of complex structures is used with good control, and errors such as 'such biometric authentication' are minor and rare.

The response directly answers the question with a clear, consistently maintained position, and both the convenience advantages and the privacy drawback are developed with relevant, specific examples and explanation.

Ideas progress logically from the introduction through convenience and privacy to a conclusion, with effective transitions and generally clear referencing. Single line breaks mark these stages; more distinct paragraph breaks would make the organisation easier to see.

Vocabulary is flexible and precise, including natural collocations like 'street vendors', 'surveillance states', 'fumbling about for money', and 'fluctuate wildly in terms of value', with only a rare slip such as 'intrusion of their privacy'.

A wide range of structures is used with strong control, including relative clauses, concessive clauses and balanced negative constructions. Minor slips include making cryptocurrency wallets, rather than currencies, the subject of “fluctuate wildly in terms of value”.
