careful to avoid danger or risk
Being very careful so that nothing bad or dangerous happens.
用法模式：
be cautious about [doing something] / a cautious [person/approach/decision]
常见错误：
Learners sometimes confuse "cautious" with "conscious" (awake/aware). Also, they may say *"cautious to"* instead of the more natural "cautious about" or "cautious with": say "be cautious about driving at night" or "be cautious with your money."
近义词
careful (Very close in meaning; more common and slightly broader in use.)
|
prudent (More formal; stresses wise and sensible care, especially with money or decisions.)
反义词

|
careless (Not giving enough attention, so mistakes or accidents are likely.)
