1、care about和care for在表示“关心,担心,”等意思的时候,用法是一样的,基本可以通用。

如,Don't care about/for me.别担心我.You needn't care for/about his safety.你不必为他的安全担心。

2、在表示“介意,计较”等意思的时候,要用care about,后面一般接表示事物的词.如,He doesn't care about his clothes.他不讲究衣着.I don't much care about going.我不太想去。

3、在表示“关怀,照顾”/“愿意...”等意思的时候,要用care for.如,We must care for the younger generation.我们必须关怀年青的一代.Would you care for a walk after supper?晚饭后去散散步好吗?

4、在表示“喜欢,愿意,想望”等意思的时候,要用care to do .即care后面接不定式.如,I don't care to go there.我不愿到那里去。
