英语形容词和副词原级的用法→两者之间的同级比较

欢迎大家来到IT世界,在知识的湖畔探索吧!

一、形容词和副词的比较等级有三个。

1.原级，即原形 ；→如：tall (高的)；quick (快的)

2.比较级，表示“更……”的意思；→如：taller (更高的)；quicker (更快的)

3.最高级，表示“最……”的意思→如：tallest (最高的)；quickest (最快的)

在两者之间，表示“更……”时，用比较级。

This room is bigger than that one.这个房间比那个房间更大。

在三者或三者以上中，表示“最……”时，用最高级。

The rabbit is the smallest of them.兔子是它们中最小的。

二、形容词和副词原级的用法→两者之间的同级比较。

1.表示比较双方程度相同时，常用“as + 形容词/ 副词原级 + as ” 结构，意为“…..和…..一样”

Tom is as tall as Jack. 汤姆和杰克一样高。

Fuzhou is as beautiful as Hangzhou. 福州和杭州一样美丽。

He runs as fast as I. 他和我一样跑得快。

Tom studies as hard as Jim. 汤姆和吉姆学习一样努力。

You write as carefully as I. 你和我写得一样认真。

2.表示比较双方程度不同时：“not as /so+ 形容词/副词原级 + as ”结构， 意为“….与…不一样”或 “……不如……”

Tom is not as /so tall as Jack. 汤姆不如杰克高（汤姆和杰克不一样高）。

The weather here is not as/so cool as that in Harbin.这的天气不如哈尔滨的天气凉快。

He doesn’t run as/so fast as I. 他跑得不如我快。

Tom doesn’t study as/so hard as Jim. 汤姆学习不如吉姆努力。

​特别注意：

①为避免双方比较名词的重复，通常用that(those),one(ones)代替前面出现的名词，that指代物,one既可指代人也可指代物，that可指代可数名词单数和不可数名词，而one只能指代可数名词。

The water in this river is clean than that in that river.

这条河的水与那条河的水一样干净。

The weather in Beijing is not so good as that in Hainan.

北京的天气没有海南的天气好。

This song sounds as beautiful as that one. 这首歌听起来与那首歌一样优美。

The girls in Class Two are as beautiful as ones in Class Six.

二班的女孩与六班的女孩一样漂亮。

②有时也可以用名词性物主代词(如：mine,ours,theirs,yours,hers等)代替前面出现的名词。

Your school is as big as mine. 你的学校与我的学校一样大。

The food was not as delicious as ours.食物没有我们的食物美味。

③ “as + 形容词/ 副词原级 + as ” 结构中，选择“形容词” 还是“副词”取决于谓语动词是实义动词还是系动词。如果是系动词就用“形容词”，否则用“副词”。

Maria cooked as successfully as Jane.玛丽煮饭与简一样成功。

I live as happily as before.我过得跟以前一样快乐。

She is writing as carefully as Lucy.她写得与路西一样认真。

Lucy is not so lovely as Lily.路西没有丽丽可爱。

This song sounds as beautiful as that one.这首歌听起来与那首歌一样优美 The food tastes as delicious as theirs.食物尝起来与他们的食物一样美味。

④在”as … as”结构前加上倍数词，表示“……是……的几倍……”

My bedroom is twice as big as yours.我的卧室是你的卧室的两倍大。

Your table is three times as long as mine.你的桌子是我的桌子的三倍长。

He runs three times faster than his brother.他跑的速度比他弟弟快三倍。

倍数词/分数/百分数+ as 形容词/副词原级+ as …

→“…..是…….的几倍/几分之几/百分之几….”

这个盒子是那个盒子的四倍重。
