PETS-3常見語法知識點(diǎn)（形容詞用法）

形容詞的用法、比較等級形式及其示例：

1、形容詞的用法

形容詞是用來修飾、描繪名詞的，通常在句中作定語、表語或賓補(bǔ)，有時(shí)還可作狀語。如：

He is honest and hardworking.

I found the book interesting.

某些形容詞與定冠詞連用表示一類人作主語時(shí)，謂語通常用復(fù)數(shù)形式。如：

The rich and the poor live in different parts of the city.

The English like to be with their families.

多個(gè)形容詞作定語修飾名詞的順序：

冠詞+序數(shù)詞+基數(shù)詞+性質(zhì)狀態(tài)(描述性)+形狀大小+新舊老少+顏色+國籍+材料+名詞。如：the second five interesting big new red Chinese wall papers.

2、形容詞比較等級的形式

(1)規(guī)則形式

一般說來，單音節(jié)詞及少數(shù)雙音節(jié)詞在后加-er;--est來構(gòu)成比較級和較高級;其他雙音節(jié)詞及多音節(jié)詞在前加more,most.如：

great-greater-greatest

busy-busier-busiest

important-more important-(the)most important

(2)不規(guī)則形式

good(well)-better-best

bad(ill)-worse-worst

many(much)-more-most

little-less-least

(3)形容詞比較等級的用法

②表示兩者以上的比較，用"the+形容詞較高級(+名詞)+of(in)…"如：

He is the cleverest boy in his class.

③表示兩者是同等程度，用"as+形容詞原級+as".如：

④越…越…

例如：The more I learn,the happier I am.

⑤You can never be too careful.越小心越好

又如：You can never praise the teacher too highly.

你怎么贊揚(yáng)這個(gè)老師也不過分。
