常見錯誤

❖ 'I have a lot of improvement in my English this year.' ✅ 'I have made a lot of improvement in my English this year.' — 'improvement' is usually paired with 'make' or 'show', not 'have'.

❖ 'The new system is a big improvement of the old one.' ✅ 'The new system is a big improvement on the old one.' — use 'on' (or 'over') when comparing the improved thing to the original.
