形容词有三个等级:原级、比较级、最高级。现将其用法解码如下:
I.一级解码——原级的用法
形容词的原级表示人或事物的特征、性质。句中只出现一个人或事物,没有比较对象时,要用原级。例如:
I am tall.我个子高。
Lily is a good student.莉莉是个好学生。

1.表示程度相同时,我们常用“as 形容词的原级 as”句型,意思是“和……一样”。例如:
She is as pretty as her sister.她和她姐姐一样漂亮。
2.表示程度不同时,我们常用“not as/so 形容词的原级 as”句型,意思是“不如”。例如:
It’s not so/as cold today as yesterday.今天不如昨天冷。
Ⅱ.二级解码——比较级用法
形容词的比较级用于二者(人或事物)的比较。基本句型为:主语 系动词 形容词比较级 than 被对比的人或事物。例如:
She is taller than I.她比我个子高。
This cake is bigger than that one.这块蛋糕比那块大。

1.在比较级前可用much,a lot,a little,even,still等词或短语修饰。例如:
My brother is much older than I.我哥哥比我大得多。
Japan is a little larger than Germany.日本比德国大一点。
2.避免与自身相比。例如:
他在班上是最高的。
误:He is taller than any student in the class.
正:He is taller than any other student in the class.
3.被比较的对象必须是同一类的。例如:
在冬天,北京的天气比广州冷得多。
误:In winter,the weather in Beijing is much colder than Guangzhou.
正:In winter,the weather in Beijing is much colder than that in Guangzhou.
Ⅲ.三级解码——最高级用法
形容词的最高级用于三者或三者以上(人或事物)的比较。基本句型为:
主语 系动词 the 形容词最高级 (n.) of/in...(表示范围)。例如:
Autumn is the best season in Beijing.在北京,秋天是最好的季节。
Mary is the shortest of the three.玛丽是三人中个子最矮的。

1.形容词最高级前常常要用定冠词,但当形容词最高级前有物主代词修饰时,则不再用。例如:
Today is his busiest day.今天是他最忙的一天。
2.当用of/in短语表示最高级的比较范围时,介词of后的名词或代词与句中的主语是同一类;只说明是在某一特定范围的比较时,用介词in。例如:
My father is the tallest in my family.在我家里,我父亲最高。
He is the happiest of us.他是我们当中最幸福的。
