be动词后到底是加形容词还是副词总结： be动词后一般是加形容词, It turns out to be good enough I am happy It is really good. 其实系表结构有两种情况： 1.be+adj 就是be加上形容词。比如You are beautiful 2.be+adv+adj在形容词前面加上一个副词修饰形容词，比如You are very beautiful 副词可以放在be的后面,但副词后面必有动词的正在进行时或过去分词或形容词，副词是修饰后面的动词或形容词的。 I am happily listening to the teacher The boss was entirely satisfied with what the workers had done. 两个典型句子，在句子中mostly, exactly都是程度副词,修饰的是整个句子 They are mostly students. 他们大部分是学生 It is exactly 9'o clock. 现在9点整。 本文来源：https://www.wddqw.com/doc/babfb64e0812a21614791711cc7931b764ce7b1a.html
