look carefully和look careful有什么区别

look carefully和look careful有什么区别

carefully 是副词，修饰动词，即look。
所以look carefully意思是：仔细地看

careful 是形容词，修饰be动词或系动词，这里的look就是系动词，用法跟be动词一样，意思是看起来。
所以look careful意思是：（某人）看起来很细心

she looks carefully at you.

一般look做实意动词要与up at等连用表示很认真的看

this boy looks careful.表示男孩看起来很细心认真
和she looks beautiful同理

look carefully就是仔细看的意思，这时候look是作实意动词；而look careful是看上去很谨慎的意思，这时look是作系动词。
