新概念英語第三冊語法總結(jié)：形容詞

定義：形容詞是用來修飾名詞的詞，描述名詞的性質(zhì)、外觀、特點等。功能：形容詞可以做定語、表語或補助語。分類：主要分為兩類：描繪性形容詞和限定性形容詞。

● 描繪性形容詞主要用來描繪大、小、新舊、顏色、質(zhì)量等。

● 限定性形容詞主要用來限定所修飾詞的數(shù)量、距離及范圍所屬等。1.當(dāng)形容詞修飾單數(shù)可數(shù)名詞時，必須與冠詞連用：

a lovely girl, the naughty boy2.形容詞可與系動詞連用，做表語，說明主語的性狀。常用系動詞有：be, become, seem, appear, feel, look, taste, smell, sound, remain, go, turn, keep, stay, etc.

The dish tastes delicious.

The music sounds sweet.

The milk went bad.

小心陷阱：feel，smell，taste，look，keep有時可以用作實義動詞，并可以用副詞修飾。

He looked me up and down carefully.

I tasted the soup slowly to see whether it was salty.3.形容詞用作后置定語。(簡單理解：一般的形容詞修飾名詞時放在名詞前面，但有些形容詞修飾名詞時放在名詞的后面)

a river navigable(一條可通航的河)

sight visible (可見的景象)

person responsible(負(fù)責(zé)人)注意：responsible person(有責(zé)任心的人)

the best way possible(盡可能好的辦法)

the number necessary(必要的數(shù)量)

the people present(在場的人)4.只能作表語的形容詞(1) 某些表示健康狀況的形容詞。

well(身體好的)，ill(病的)，faint(虛弱的)，poorly(身體不好的)

示例：His mother has been ill for a long time.

特別注意：sick是個特例。它既可做表語，又可做定語。

He is sick for a couple of days.(他病兩三天了)

He is a sick person.(他是個病人。)(2) 某些以 a-開頭的形容詞。

如：afraid, alone, alive, asleep, awake, aware

The old man is alone in the house.(老人一個人在家。)

The teacher is alive with enthusiasm.(這位老師熱情洋溢。)

He is asleep in his mother's arms.(他在母親的懷抱中睡著了。)

I have been aware of the difficulty.(我已經(jīng)意識到了困難。)
