后接介词 of 或 about, 表示“当心”、“留意”等.如：

You must be careful of [about] your pronunciation. 你要注意你的发音.
注：be careful 后一般不接介词 for.如：
我希望你要多注意身体.正：I hope you’ll be more careful of[about] your health.
误：I hope you’ll be more careful for your health.
2. 后接介词 with(其后多接名词)或 in(其后多接动名词),表示做某事时很小心或仔细.如：
He’s careful with [＝in doing] his work. 他工作很仔细.
Be careful with the vase; it is valuable. 这花瓶很贵,小心点.
Be careful in dealing with such people. 和这种人打交道要小心.
3. 后接不定式.如：
Be careful not to drop it. 小心不要把它掉了.
You must be careful to avoid being caught. 你必须小心,不要被抓住.
比较：
He’s careful to read every sentence. 他注意读(即不漏读)每一个句子.
He’s careful in reading every sentence. 他读每个句子都很仔细.
4. 后接从句.如：
Be careful how you hold it. 小心拿好.
Do be careful what you say. 说话一定要小心.
Be careful that you don’t hurt her feelings(＝Be careful
not to hurt her feelings). 当心别伤害她的感情.
注：后接 what 从句时,可用介词 of, about 等,但通常省略,但是若是接 that, how, when, where 等引导的从句,则一般不用介词；另外,从句谓语若指将来,通常要用一般现在时代替将来时( 见上例).
Be careful about what you say。
Please be careful with the strangers when you are at the groceries store.
