(一)、基數(shù)詞

【形容詞,副詞】
形容詞及其用法
形容詞修飾名詞,說明事物或人的性質(zhì)或特征。通常,可將形容詞分成性質(zhì)形容詞和敘述形容詞兩類,其位置不一定都放在名詞前面。
1) 直接說明事物的性質(zhì)或特征的形容詞是性質(zhì)形容詞,它有級的變化,可以用程度副詞修飾,在句中可作定語、表語和補語。例如:hot 熱的。
2) 敘述形容詞只能作表語,所以又稱為表語形容詞。這類形容詞沒有級的變化,也不可用程度副詞修飾。大多數(shù)以a開頭的形容詞都屬于這一類。例如:afraid 害怕的。
(錯) He is an ill man. (對) The man is ill.
(錯) She is an afraid girl. (對) The girl is afraid.
這類詞還有:well,unwell,ill,faint,afraid,alike,alive,alone,asleep,awake 等。
3)形容詞作定語修飾名詞時,要放在名詞的前邊。但是如果形容詞修飾以-thing為字尾的詞語時,要放在這些詞之后,例如:something nice
用形容詞表示類別和整體
1) 某些形容詞加上定冠詞可以泛指一類人,與謂語動詞的復(fù)數(shù)連接。如:the dead,the living,the rich,the poor,the blind,the hungry
The poor are losing hope.
2) 有關(guān)國家和民族的形容詞加上定冠詞指這個民族的整體,與動詞的復(fù)數(shù)連用。
the British,the English,the French,the Chinese.
The English have wonderful sense of humor.
以-ly結(jié)尾的形容詞
1) 大部分形容詞加-ly可構(gòu)成副詞。但 friendly,deadly,lovely,lonely,likely,lively, ugly,brotherly,仍為形容詞。
改錯:(錯) She sang lovely. (錯) He spoke to me very friendly.
(對) Her singing was lovely. (對) He spoke to me in a very friendly way.
2)有些以-ly 結(jié)尾既為形容詞,也為副詞。
daily,weekly,monthly,yearly,early
The Times is a daily paper. The Times is published daily.
多個形容詞修飾名詞的順序
多個形容詞修飾名詞時,其順序為:
限定詞--數(shù)詞--描繪詞--(大小,長短,形狀,新舊,顏色) --出處--材料性質(zhì),類別--名詞
a small round table a tall gray building
a dirty old brown shirt a famous German medical school
an expensive Japanese sports car
worth 的用法
worth,worthy,worth-while都為adj. 意為"值得"。
1. worth:be worth + n. 當(dāng)名詞為金錢時,表示"…… 值得……"
be worth doing sth. "……某事值得被做"
The question is not worth discussing again and again.
2. worthy:be worthy of +n. 當(dāng)名詞為抽象名詞時表示"……值得……"

典型例題

A.worth B.worthy C.worth-while D.worth while
答案C. 由worth的用法可知,此句只適合詞組be worth-while to do sth.。
公共英語一級考試閱讀提點練習(xí)
part 1
In a good cartoon, the artist can tell in a few lines as much as a writer can tell in half a dozen paragraphs. The cartoonist not only tells a story but he also tries to persuade the reader to his way of thinking. He has great influence on public opinion. In a political campaign, he plays an important part. Controversial issues in Congress or at meetings of the United Nations may keep the cartoonist well-supplied with current materials.
A clever cartoonist may cause laughter because he often uses humor in his drawings. If he is sketching a famous person, he takes a prominent feature and exaggerates it. Cartoonists, for instance, like to lengthen an already long nose and to widen an already broad grin. This exaggeration of a person’s characteristics is called caricature. The artist uses such exaggeration to put his message across.
Useful Words and Expressions:
1. cartoonist 漫畫家
2. campaign 活動
3. controversial 爭論的,爭議的
4. sketch 素描
5. prominent 卓越的
6. exaggerate 夸張
7. lengthen 延長
8. grin 露齒笑
part 2
“House” and “home” are two words that have similar meanings.
“House” and “home” both refer to places where people live. However, there is a difference between them. “Home” is often referred to as the place that we live in with our families. Sadly, in our society, people can hardly distinguish a home from a house because they often see no difference between them. This confusion can be traced back to the indifference between family members. Therefore, we can say that love is an important factor in a home. A home is a shelter, not only for our bodies but also for our minds. Whenever we are depressed, we can go home for comfort. Everyone in the family will do his best to take care of each other and share their happiness as well as sorrow. Without love, a home is merely a house where loneliness is all that can be found. And a house can never be a home unless there is love.
Useful words and expressions:
1. refer to 提到
2. distinguish區(qū)別,辨別
3. confusion 混亂,混淆
4. trace back 追溯到
5. indifference 不關(guān)心
6. depressed 沮喪的
