be careful & be carefully

其實首先你要明白個be是代表甚麼，是甚麼意思。

be基本上是一個概括is/am/are/were/was的動詞。或者可以這樣睇be=is/am/are/were/was.

be後面不能只跟副詞(即係carefully)
be後面卻可以跟形容詞(即係careful)

其實有很多例子可以證明
例如 I am(BE) happy(形容詞).
I am(BE) careful(形容詞).我很小心.
You should be careful.>>變成警告語句>>會寫成>>be careful

反而副詞carefully是這樣用的(副詞是用來描述動作的動詞)

I walk carefully.>>變成警告詞句>>會寫成>>walking carefully.

希望你明白啦

Be Carefully

be carefully is wrong.

careful is an adjective.

carefully is an adverb.

Please put the thing carefully.

be carefully is wrong.

若果叫人小心

應該係

be careful
watch out
take care

有咩分別?
點用先岩?
it's the same as post #1

叫人小心d ge英文係 be careful
careful係一個adjective(形容詞)
而carefully係一個adverb(副詞)
adjective係用黎為某人or物添加細節
而adverb係用黎為一個action添加細節
2者係唔同嫁!!
例子:
This boy has a loud voice
這個男孩有一個響亮的 嗓門
loud係一個adjective,係呢句句子入面,話俾讀者聽呢個男仔ge嗓門係好響亮ge
voice係一個noun(名詞)

The dog barks loudly
這隻狗高聲地 吠
loudly係一個adverb,係呢句入面 話俾讀者聽隻狗吠得好大聲
bark係一個verb(動詞)
