常見錯誤

❌I downloaded the codec software for write a music file.
✅I downloaded the codec software to write a music file.
💡use to-infinitive of purpose after a verb of action, not 'for + bare verb'.
❌My player does not have any codec to read this format.
✅My player does not have a codec that can read this format.
💡pair 'codec' with a relative clause when describing what it does; 'any codec to read' sounds unnatural.
