Question

be动词后是形容词还是副词

be动词后是形容词还是副词
比如是：be careful
还是：be carefully???

Answer 1

不能笼统地说be后面接什么，要是做表语或定语的话一般只接形容词，但是后面可以跟副词修饰另外一个词，如
He is beautiful (直接接形容词做表语）
The house is beautifully decorated（be后面接副词，修饰后面的动词）
She is very clever （very也是副词，修饰形容词clever）
你问的例子也是两种都有可能，关键是你要用哪个
He is careful .
The house is carefully checked

追问

照你的说法，，那么you must be_____( careful),,是原形了咯

追答

是的，后面没有别的词的话说明careful做be的表语

追问

如果后面还有一串定语呢，一样吗

追答

后面一般也不叫定语，应该是表语，有时前面可以加副词的

Answer 2

[be careful] 形容词放在be动词之后。eg：The flower is beautiful.花很漂亮

Answer 3

两者兼可，要按语境决定。例：
Please be careful when you cross the road.
The flowers are carefully placed in the vase to produce a perfect floral arrangement.

Answer 4

形容词，构成主系表结构，也就是说应该是be careful

Answer 5

形容词~~~be happy~~~be good be careful~~~
