Adjectives
形容词是一个词，如“高大”、“孤独”或“教育的”，用来描述或提供有关人或事物的更多信息。形容词通常在名词之前，在存在和感知动词之后，如“味道”和“感觉”。
示例:
That is a very tall man.
He's such a lonely puppy when I'm at work.
We watched an educational movie.
There was a sweet taste in my mouth.
The old, dark house gave me a bad feeling.
形容词语序
当多个形容词一起使用时，有一个语序：
数量、价值/意见、尺寸、温度、年龄、形状、颜色、来源、材料
The tall (size) Chinese (origin) vase was worth a lot of money.
My favourite (value/opinion) old (age) blue (colour) sweater was ruined in the wash.
The cold (temperature) round (shape) metal (material) touched my arm and shocked me.
使用形容词进行比较
要比较两个相等事物的属性，使用这个结构：
as+形容词+as
Coco is as thirsty as Steve.
She is as tall as her best friend.
The string is as long as the table.
要比较两个不相等事物的属性，请使用以下结构：
not as+形容词+as
少于+形容词+than
形容词+ than
They are not as cool as the others.
Miranda is not as funny as her sister.
They are less cool than the others.
Miranda is less funny than her sister.
The others are cooler than them.
Yoko is funnier than Miranda.
描述数量的形容词
当比较相等的事物时，使用这个结构：
as+表示数量的形容词+（名词）+as
I had as many books as a library has in my house.
There were as many dogs as there were people at the party.
If I had as few problems as you do, I would be more relaxed.
当比较不相等的事物时，使用这个结构：
表示数量的形容词+（名词）+than
Sarah has more pens than her sister.
The big monkey has fewer nuts than the small monkey.
We have had more success than they have.
The company made less money than it did last year.
形容词比较级
比较形容词让我们能够比较两个名词。以下是与比较形容词一起使用的结构：
名词（主语）+动词+比较形容词+than+名词（宾语）。
大多数比较形容词都是在形容词的末尾加上“r”或“-er”，或在形容词前面加上“more”。
| 形容词 | 比较的 |
|---|---|
| 小 | smaller |
| 宽 | wider |
| strong | stronger |
| happy | happier |
| intelligent | more intelligent |
| important | more important |
The fir tree is stronger than the pine tree.
My friend is older than your friend.
Your health is more important than your need for sweet snacks.
绿色和红色的糖果都很好吃，但我更喜欢绿色的。（“…比红色的”是暗指）。
最高级形容词
最高级形容词比较三个或以上的名词，使名词的比较达到最高程度。以下是构建的方法：
名词（主语）+动词+the+最高级形容词+名词（宾语）。
大多数最高级形容词都是在形容词后面加上“-est”或在形容词前面加上“most”。
| 形容词 | 最高级 |
|---|---|
| 小 | smallest |
| 宽 | widest |
| strong | strongest |
| happy | happiest |
| intelligent | most intelligent |
| important | most important |
Jim's mom is the most intelligent person I know.
