2. 比较级，表示“较……”或“更……一些”的意思。
3. 最高级，表示“最……”的意思。
一、原级使用原级一般有两种情况：1. 当不进行比较时，在程度副词very, so, quite, too等后面的形容词或副词要用原级。
例如：This box is too heavy. 这个箱子太重了。
She speaks English very well. 她英语讲得很好。
2. 在“as…as”或“not as/so…as”结构中，虽有比较的意思，但形容词或副词要用原形。
例如：This ruler is as long as that one. 这把尺子和那把尺子一样长。
Jim is not as/so tall as Tom. 吉姆不如汤姆高。
二、比较级表示两者（人或事物）之间的比较时，一般要用比较级。
1. than前面的形容词或副词要用比较级。
You are taller than your brother. 你比你弟弟高。
He jumped higher than you. 他比你跳得高。
2. 形容词或副词前有much, a lot, a little, far, still, even等词时，要用比较级。
例如：He studies even harder. 他学习更努力了。

This story is much more interesting than that one. 这个故事比那个有趣的多。
三、最高级表示三者或三者以上的人或物比较时，要用最高级，其中有一个在某方面超过了其他几个。
形容词最高级前要用定冠词the，副词前可不用the。
最高级一般要与表示比较范围的介词in或of连用。
of后面常接可数名词复数或all等代词，主语和of后的名词或代词属于同一个概念范畴；in后一般跟一个组织、单位、团体之类的集体名词，主语和in后面的名词不是同一概念范畴。

英语形容词和副词的比较级和最高级
英语形容词和副词的比较级和最高级英语形容词和副词的比较级和最高级是英语语法中的一个重要部分，它们用于表示事物之间的程度差异。
在英语中，形容词和副词有三种形式：原级、比较级和最高级。
1. 原级（Positive Degree）：表示事物的正常状态或基本程度。
例如：happy（快乐的）、quickly（快速地）。
2. 比较级（Comparative Degree）：表示两个事物之间的程度差异。
比较级的构成方式有两种：a) 在形容词和副词后面加-er。
例如：bigger（更大的）、faster（更快的）。
b) 对于以字母e结尾的形容词和副词，只需在后面加-r。
例如：nice（好的）→nicer（更好的）、large（大的）→larger （更大的）。
c) 对于以一个辅音字母加一个元音字母结尾的双音节形容词和副词，以及以重读闭音节结尾的多音节形容词和副词，需要在前面加more。
例如：beautiful（美丽的）→more beautiful （更美丽的）、carefully（小心地）→more carefully（更小心地）。
3. 最高级（Superlative Degree）：表示三个或三个以上事物之间的程度差异。
最高级的形式分为两种：a) 在形容词和副词前面加the。
例如：the biggest（最大的）、the fastest（最快的）。
b) 对于不规则变化的形容词和副词，需要单独记忆其最高级形式。
例如：good（好的）→the best（最好的）、bad（坏的）→the worst（最坏的）。
在使用比较级和最高级时，需要注意以下几点：1. 当比较的对象是同一类事物时，可以使用比较级或最高级。
例如：My car is faster than yours.（我的车比你的车快。
）2. 当比较的对象不是同一类事物时，不能使用比较级或最高级。
例如：My car is faster than a bicycle.（我的车比自行车快。

B.英语中常见的表示“最高程度”的形容词有excellent、extreme、perfect等，它们没有最高级，也没有比较级。
C.此外，英语中有些词和短语不用比较级形式却表示比较级概念，如：minor（较小的）、senior（年长的、高级的）、junior（青少年的）、prior（事先的、优先的）、inferior（次的、低等的）、superior （上级的、更好的）、prefer to（更加喜欢、宁愿）、preferable（更好的、更合适的）2.形容词比较级、最高级规则变化注意：多音节或部分双音节词，也可加less（不如、不像）或least eg. I am less outgoing than my sister. 我不如我的姐姐外向。
3.形容词比较级、最高级不规则变化二、形容词和副词原级的用法1.表示A与B在某一方面相同或不同时，用adj/adv的原级，表示两者在某一方面相同时，用“as+adj/adv原级+as”句型；表示一方在某方面不如另一方时，用“not+as/so+adj/adv原级+as”句型。
