副词其实和形容词的概念差不多，形容词是用来修饰名词，而且只能修饰名词，说明名词的属性和特征；相比之下，副词不会与名词有任何关联，它是用来修饰动词、形容词或者整个句子的。
比如He is walking quickly to school. 这里的quickly就是副词，用来指明动词walk的特征是快不是慢或其它。
副词的用法很灵活，但基本思路是修饰哪个词就跟在哪个词前或者后，比如刚才的walk quickly，还有very beautiful中的very。另外还有一类句子副词，用法相对独立，不与单个词联系，比如 Frankly, She is more beautiful than you.
需要说明的是，副词如果使用得当，可以使整个句子提升一个档次，比如Modern science and technology is developing more and more rapidly. 如果使用副词可以更简洁地表达为Modern science and technology is developing increasingly rapidly.
