形容词的比较级：
当两种物体之间相互比较时，我们要用形容词或副词的比较级；
当相互比较的物体是三个或三个以上时，我们就要用形容词或副词的最高级。

形容词的比较级和最高级用法：形容词比较等级用法： 1.没有比较对象时，用原级。

3.程度副词用在助动词与一般动词之间。

5.程度副词much(…得多)，even(更加)可在形容词或副词的比较级之前作修饰语。

程度副词和强调副词：
1、程度副词可修饰动词，表示“到某种程度”：
He loved his mother dearly. 他深爱他的母亲。
I strongly object to your saying that. 我强烈反对你这样说话。
Is she badly hurt? 她伤得重吗？
这类副词除修饰动词外，还可修饰形容词（a）或另一副词(b):
a. fairly simple 相当简单
awfully sorry 非常抱歉
quite correct 完全正确
truly grateful 确实很感激
b. fairly smoothly 相当顺利地
wonderfully well 好极了
know fully well 完全清楚
do it very quickly 干得很快
2、强调副词和程度副词很接近，有些就是程度副词。它们主要是对所修饰的动词(a)、形容词（b）加以强调：
a. I quite agree. 我完全同意。
He knew absolutely nothing. 他是毫无所知的。
Your attitude simply amazes me. 你的态度简直使我吃惊。
b. You’re entirely wrong. 你完全错了。
She’s perfectly correct. 她完全正确。

3）much 是一个特殊的程度副词，它可以：
a. 修饰副词（特别是用在否定句中）：
She didn’t talk much. 她不怎么说话。
I don’t much like the idea. 我不大喜欢这个想法。
Thank you very much. 非常感谢你。
b. 修饰形容词等；
I’m not much good at singing. 我唱歌不太好。
I’m very much afraid that she won’t come. 我很担心她不来。
c. 和形容词或副词的比较级或最高级连用：
You sing much better than me. 你比我唱的好多了。
Their house is much nicer than ours. 他们的房子比我们的好多了。
d. 和how, so , too等词连用：
How much do you like him? 你喜欢他到什么程度？
He would so much like to go. 他会很想去的。
程度副词的用法注意点：
(1) 程度副词主要用于修饰形容词和副词,有的还可修饰比较级(如much, rather 等)和最高级(如quite, much, almost 等)。如:
Houses are much more expensive these days. 如今的房价贵多了。
This is quite [much] the most expensive radio here. 这是这里最贵的收音机。
【说明】quite 有时也修饰比较级,但只用于quite better(身体康复)这一表达。
(2) 有的程度副词(如quite, rather, almost等)可修饰动词,但有的(如fairly, pretty, very等)则不能修饰动词。如:
I quite agree with you. 我完全同意你的意见。(不用fairly, pretty, very)
We rather like the film. 我们很喜欢这部电影。(不用fairly, pretty, very)
(3) 个别的程度副词(主要是quite和rather)还可修饰名词(注意词序)。如:
It’s quite [rather] a good idea. / It’s a quite [rather] good idea. 那可真是个好主意。
若此结构中没有形容词,则 quite 和 rather 则只能放在冠词之前。如:
It was quite [rather] a success. 那事相当成功。
