意味
Used to express confidence or certainty about a statement.
文化的背景
Americans value directness. 'I'm sure' is a standard way to show you are a person of your word. In the UK, people might add 'I'm fairly sure' to be polite and avoid sounding too pushy. Direct certainty can be seen as blunt. People often use 'I think' even when they are sure. Germans appreciate precision. 'I'm sure' is taken as a factual statement, so don't say it unless you are certain.
Contractions
Always use 'I'm' instead of 'I am' in casual conversation to sound more natural.
Don't over-promise
If you are not 100% sure, say 'I'm pretty sure' instead.
