①系动词和普通的动词有什么区别,系动词后面加什么（举例说明）②除了动词修饰副词,还有什么修饰什么

联系动词后面要接名词,代词,形容词、介宾结构作表语,才有完整意义,意思为“是”、“在”、“变得”、“感觉”、“闻起来”、“尝起来”、“听起来”、“仍然是”的意思.
She was upset.
The dog's hair grows thick.
The milk went sour.
My dream came true.
He lies still on the bed.
My uncle stayed a bachelor all his life.
The material feels soft.
The pizza tasted a little too salty.
The pizza smelt very good.
副词是修饰一般动词的,但也可以修饰形容词和副词,比如：
The boy threw the ball quickly.
The boy threw the ball quickly there twice yesterday.
The very small boy threw the ball quickly.
She drove rather quickly.
worry有三种用法.
作及物动词,相当于汉语文言文里的使动用法,使担心.
My grandma's illness worries me very much.
作不及物动词,表示担心,又分为两种用法.
I worry about my grandma so much.
I am worried about my grandma so much.
希望我能帮助你解疑释惑.

worry这个词有点特殊， be worried about和worry about 意思一样， 都是为什么人或者事担心
something worries me, 某事让某人担心

1.系动词是动词的一种，还有实意动词，助动词，情态动词等。
系动词（be，is ,am ,are...feel，smell）后面加名词或者形容词构成表语，比如：
He is handsome.他很帅。（形容词）
He is a student.他是一名学生。（名词）
2.说反了，应该是副词修饰动词。副词本身也可以修是副词。比如：
He runs really...
