Band 7+: Which do you prefer, e-books or paper books ?

Your pronunciation is very good. Aim to refine subtleties and intonation to further improve.

This is a good start to answering the question. To improve, consider elaborating on your reasons. For example, you could discuss the convenience of e-books in more detail, or perhaps mention specific features you enjoy, such as adjustable font sizes or the ability to search for words. You could also briefly touch upon any drawbacks of e-books to show a balanced perspective. The response could be expanded as it currently feels quite brief.

The answer is coherent and easy to follow. The slight hesitation between 'expensive' and 'and' could be improved by smoother transitions. Perhaps adding a brief pause after 'expensive' would help.

Vocabulary is adequate and appropriate for the topic. More sophisticated vocabulary could be used to describe the advantages of e-books, such as 'convenient' or 'portable' instead of 'easily carry'.

Grammar is accurate. The use of a simple sentence structure is effective for clarity. To demonstrate a wider range, consider using more complex sentence structures, such as subordinate clauses, in future responses.
