序数词的用法 1到10的序数词

1.比较级用法

基本句型：主语+be+比较级+than+比较对象

两者相比较用比较级 eg：Who do you think is more outgoing，Lily or Lucy？

very，more，quite，so，too等修饰原级；much，a little，a lot，a bit，far ，even等修饰比较级

eg：I’m much/ a little / a lot / a bit /far more outgoing than my sister.

I’m even worse now.

不能与人或事物自身相比较

eg：He is taller than any other student in his class.

China is larger than any country in Africa.

比较对象要一致（that代替不可数名词，those代替可数名词复数，所有格，ones）

eg：The weather in Harbin is much colder than that in Wuhan.

比较级中出现of the two/ twins结构时，adj比较级前要+the，不可用than

Eg：Tom is the taller of the two brothers.

“get/ become+ 比较级+and +比较级”表示“变得越来越……”（多音节或部分双音节用“more and more+原级）

Eg: It gets warmer and warmer when spring comes.

You’re getting more and more beautiful.

“the+比较级……，the+比较级……”表示“越……，就越……”

Eg: The more you exercise, the stronger you will be.

“as…as”中间接原级，表示“与…一样”，否定为“not as/ so…as”表示“不如”

Eg: He is as tall as his father.

He is not as/ so tall as his father.

“比较级+than”(more/ less +原级+than)与“not as/ so…as”可以互换

比……大/多/长/宽几倍，用“主语+be+……times+比较级+than+比较对象”

Eg: Our classroom is twice larger than yours.

重几斤，高几公分，大几岁……，用“主语+be+数量词+比较级+than+比较对象”

Eg: I’m six years older than you.

2.最高级的用法

用于三者或三者以上的比较 eg：Which do you like best，Chinese，Math or English？

“one of+最高级+n.复数”表示“最…之一”

Eg：Lu Xun is one of the greatest writers last century.

“the +序数词+最高级+n.单数+范围”表示“在…范围内…是第几…”

Eg：Hainan is the second largest island in China.

先行词被最高级或序数词修饰，只能用that引导定语从句

Eg：My cousin is the funniest person（that） I know.

This is the first letter（that）I received from my sister.
