要點(diǎn)：比較級(jí)是兩者或者兩部分之間進(jìn)行比較。兩者比較要用比較級(jí)。than 比。

比如說(shuō)：

他比Jim高。

這條河流比那條河流長(zhǎng)。

這本書(shū)比那本重。

He is taller than Jim.（比較級(jí)的時(shí)候，就不能用原形了。）

（tall-taller；long-longer；heavy-heavier）

要點(diǎn)：最高級(jí)就是三者或者三者以上進(jìn)行比較，注意比較的范圍。

比如說(shuō)：

他是我們?nèi)齻€(gè)最高的一個(gè)。

這個(gè)房子是所有的房子中最大的一個(gè)。

（tall-tallest；big-biggest）

你知道比較級(jí)和最高級(jí)是如何構(gòu)成的嗎？

必須要知道！

第一種情況：如圖所示：

?

第二種情況：部分雙音節(jié)與多音節(jié)的詞比較級(jí)在原級(jí)之前加more, 最高級(jí)在原級(jí)之前加most

beautiful---more beautiful---most beautiful

interesting---

difficult---

第三種情況：不規(guī)則變化的形容詞:

little （原形） - less （比較級(jí)）- least（最高級(jí)）

good/well（原形） - better（比較級(jí)） - best（最高級(jí)）

bad/ill （原形） - worse（比較級(jí)） - worst（最高級(jí)）

far （原形）-- further—furthest

many/much——more——most

few——fewer——fewest

例句展示：

Tom is tall. John is tall. Bob is tall.

I'm as tall as you. Tom is as tall as John.

A as+形容詞或者副詞原形+as B 這是原級(jí)比較，

Bob is taller than John.

John is the tallest of the three.

John is the tallest in his class.

常見(jiàn)的用法如下

一、 在…than…句中，這是常見(jiàn)的比較級(jí)用法

He is taller than I.（口語(yǔ)中常作：He is taller than me.）

他比我高。

He is two heads taller than I.

他比我高出兩個(gè)頭。

二、 比較級(jí)and比較級(jí)，表示越來(lái)越……

It‘s getting darker and darker.

天越來(lái)越黑了。

He is getting more and more interestedin sports.

他對(duì)體育越來(lái)越感興趣。

備注：如果是多音節(jié)的話(huà)，用more and more+adj./adv.

More and more beautiful；more and more carefully

三、 The +比較級(jí)，the +比較級(jí)， 表示越……，越……

The more you eat， the more you want.你越吃越想要。

四、 在which…or…？句中，表示兩者比較

?

五、形容詞比較級(jí)前可受much,far,a lot,still,no,a little,even,any 修飾，表示超出的程度
