Band 6+: Ecology problems in the ocean

Your pronunciation is above average. However, you may find complexity in certain words challenging. Regular practice should aid in improvement.

The response is relevant to the question and demonstrates some understanding of the topic. However, it lacks depth and detail. Consider expanding on specific examples of marine species affected and the types of pollution, providing more specific details to support your points. Elaborating on the consequences of these ecological problems would also strengthen your answer.

The answer is understandable but lacks a smooth flow. There's some repetition and the structure could be improved. Try to plan your response briefly before speaking to improve coherence. Adding a concluding sentence would also help.

Vocabulary is adequate but could be more precise and sophisticated. Instead of 'a lot of marine species suffers,' try 'numerous marine species are affected.' The phrase 'other chemicals polluted things' is unclear; more specific examples would improve the answer.

There are grammatical errors, such as subject-verb agreement ('Ecology problems...is'). The sentence structure is sometimes awkward. Focus on improving sentence structure and subject-verb agreement to enhance grammatical accuracy.
