much 和well 都可以用作程度副词，前者使用范围最广，而well 的用法相当受限。

much 主要修饰以下成分：

第一类：以a- 开头的表语形容词前，如afraid, alike, alone, ashamed 等，可用much 修饰。例如：

He is very much afraid.

他很害怕。

The twins are much alike.

这对双胞胎长得很像啊。

She felt much alone and misunderstood. 

她觉得非常孤独，得不到别人的理解。

第二类：much 可以修饰由过去分词变来的形容词，因为这些过去分词形容词仍然具有动词的意味。例如：

I was much surprised at the news.我对这个消息感到十分惊讶。

The atmosphere of the city is much polluted. 那个城市的空气受到严重污染。

He was much delighted with the results. 他对这个结果感到非常满意。

第三类：much 还可以修饰具有动作性质的介词短语，例如：

此外，very much可以用在比较级之前，但very不可以。例如：

I'm very much happier in my new job. 我在新的工作岗位上开心多了。（不能说：... very happier.）

much可以修饰比较级。如：

第四类：much 常跟very 连用，修饰 like, love, prefer, hope, wish, expect, want, miss, intend, mean, enjoy, would like, feel like, hate, regret, admire, thank, appreciate, believe, trust, look forward to, think of 这些动词（或词组）。这些词语有一个共同特点，就是表达人的“欲想，好恶，观念”等概念。例如：
