英語作為當(dāng)今的主流語言,越來越受到大家的重視。四六級是大學(xué)里面的一項考試,下面是小編給大家分享的四級考點,大家可以作為學(xué)習(xí)的參考。

一、代詞

代詞中主要講解六個問題

(一) 掌握代詞的幾種格

主格、賓格、所有格

名詞前面用代詞來修飾,只能用所有格(my books)

(二) 反身代詞

當(dāng)主語和賓語表示同一事物時,賓語使用反身代詞。

He killed himself. (他自殺了)

He killed him. (他殺了他)

例:Researchers(A) at the University of Colorado are(B) investigating a series of indicators that could(C) help themselves(D) to predict earthquakes.

分觶篋錯,應(yīng)改為them。如果用反身代詞themselves,指代對象是從句主語that(即名詞indicators),這顯然是錯誤的。從句意來看,help的賓語應(yīng)該是主句主語researchers,故應(yīng)用代詞賓格而不是反身代詞。注意C并沒有錯,情態(tài)動詞could 比can語氣弱,表示較小的可能性。

Indicator為征兆,這些征兆幫助他們來預(yù)言地震。主語是征兆,后面指研究者,不是同一個事物

(三) 代詞的單復(fù)數(shù),代詞的性別

在考試中如果代詞打橫線,代詞錯誤的概率是非常高的,因此代詞打橫線,應(yīng)該先看代詞有沒有錯。

例:The continental divide refers to an imaginary line in the North American Rockies that divides(A) the waters(B) flowing into(C) the Atlantic Ocean from (D)it flowing into the Pacific.

分析:D錯,應(yīng)改為those。D指代復(fù)數(shù)名詞waters, it是單數(shù),顯然是錯誤的,根據(jù)習(xí)慣故改為those。注意waters一詞并沒有錯,它指江湖河海中的大片水域,可用復(fù)數(shù)形式。

Water作為水是不可數(shù)名詞,waters表示水域,通常使用復(fù)數(shù)形式,作主語謂語動詞用復(fù)數(shù)。

Work作為工作是不可數(shù)名詞,work作為作品,可數(shù)不可數(shù)都可以,例如:

Many of his works= much of his work, work都表示作品

例:In 1920 the presidential candidate Warren Harding(A) coined the word “normalcy” to(B) express social and economic(C) conditions they(D) promised the nation.

分析:D錯,應(yīng)改為he。動作promised是由Warren Harding發(fā)出來的,故用第三人稱單數(shù)he來指代。

例:Many critics believe(A) that Amy Lwell' s most important work(B) is not poetry, but his(C) biography, John Keats, published (D)the year of her death.

分析:C錯,應(yīng)改為her。his指男性,顯然是錯誤的,應(yīng)改為her與后面的her同指Amy Lowell.

(四) Who和which的區(qū)別

which指代事物或者動物,who指代人

who/whom son往往要改為whose son, whose可以指代事物

例:The human body contains more(A) than six hundred muscles who ( B ) account for (C)approximately forty percent of(D) the body weight.

分析:B錯,應(yīng)改為which或that。先行詞不是指人,而是指物,關(guān)系代詞不能用who,故改為which或that。

人體前面加定冠詞the, account for 占有多大的比例,解釋說明

(五) that和which的區(qū)別

介詞后面使用which, 而不用that, in that除外

例:When television was first introduced(A), the extent to that(B) it would affect(C) society could not have been foreseen(D).

分析:B錯,應(yīng)改為which。The extent to which, 介詞加which(引導(dǎo)定語從句),影響社會的程度沒有被預(yù)見

(六) 定語從句的特殊省略

Reason后面有定語從句,中間往往省略why,

Time后面有定語從句,中間往往省略when

I do remember the time I heard the sweetest voice in the wild world.

way后面有定語從句,中間省略了in which

例:Research on pain has been neglected(A), although the mainly (B) reason people take(C) medicine is to(D) relieve pain.

分析:B錯,應(yīng)改為main。mainly為副詞,不能修飾后面的名詞,故改為形容詞main。句子中people take medicine修飾reason,定語從句引導(dǎo)詞被省略

例:Commercial expansion from city to suburb has

affected the way people in the United States----.

(A) living and working

(B) they live and work

(C) live and work

(D) to live and to work

分析:選擇C, the way people....影響了人們生活和工作的方式。
