be carefulluy 和be careful 的区别

carefulluy 这个单词打错了吧,只有carefully,carefully是副词只能修饰动词,be carefully的说法不对,As long as you drive carefully,you will be very safe.
如果你开车小心,你就会很安全.这里carefully是修饰drive的.而be careful =carefully,careful是形容词,be是系动词,也可以单独使用,是小心的意思例如 Be careful crossing the road.
过马路要当心.

careful是形容词 carefully是副词
please be careful 中的careful是形容词表语 修饰be
he is carefully driving a car 中的carefully是副词状语 修饰driving

eg:please be careful. 小心
eg:he drives carefully. 他小心地驾车
