【明報專訊】I spend considerable time as a university lecturer and public speaker trying to persuade Chinese speakers to improve their English. This is no mere academic exercise. There are practical reasons why your written English should be correct and understandable. If it's not, misunderstandings can occur. Money can be lost, or time wasted. You might fail to communicate an important point because the person on the receiving end has no idea what you're trying to tell him.
