一、數詞竟然有復數,平時學習不注意

難點介紹:

對數詞的掌握不少同學建立在基數詞、序數詞及其轉換上,很少有人會想到數詞的復數形式,結果造成高考中的失分。

題例分析:

例1:It is rare in ________ that people in ________ fifties are going to university for further education.

A. 90s; the B. the 90s; /

C. 90s; their D. the 90s; their

析:D。 第一空表"在90年代",應用in the 90s短語;第二空表"在他們五十多歲時",應用 in their fifties短語,但不少同學不了解數詞的復數形式,結果只能亂選一氣。

例2:All of the students came into the classroom by ________.

A. two and three B. twos and three

C. two and threes

D. twos and threes

析:D。三三兩兩應表達為by twos and threes,但有些同學因對數詞的復數形式缺乏了解而造成解題錯誤。

例3:It is said that this terrible matter happened in ________.

A. eighties B. eighty C. the eighty D. the eighties

析:D。in the eighties表"在八十年代",符合題意,但有些同學因對這種語法現象知之甚少而造成解題錯誤。

應對方法:重視數詞的復數形式,熟悉數詞的復數形式,如by twos and threes三三兩兩,in the eighties在八十年代;in his forties在他四十多歲時;in the 1980's/1980s在二十世紀八十年代。

二、特殊數詞記不住,考試難免會出錯

難點介紹:

不少同學對基數詞、序數詞非常熟悉,但對分數、百分數、半數、倍數等特殊數詞形式不太了解,即使有所接觸也因其形式復雜而失分。

題例分析:

例1:It is reported that the United States uses ________ energy as the whole of Europe.

A. as twice B. twice muchC. twice much as D. twice as much

析:D。該題考查倍數的表達方法,其結構為:A... times as 形容詞/副詞原級as B,不少考生沒記住這個結構,結果造成失分。

例2:He did it ________ it took me.

A. one-third a time

B. one-third time

C. the one-third time

D. one-third the time

析:D。分數的表達方式為:先講分子,再講分母,分子用基數詞,分母用序數詞,分子大于1時分母用序數詞的復數形式,中間加連字符號。分數應放在所修飾的名詞前面。不少考生對分數構成及其用法特點缺乏了解,容易造成失分。

例3:Can't you see this map is _______ small as that one?

A. half as B. as half C. two-ninth as D. two as

析:A。 A是B...的一半可表達為:A is half as...as B。但如果記不住這一結構,在極易混淆的備選答案前考生難免莫衷一是。

例4:Look, this bridge is only ________ that one.

A. as long as four-fifths B. four-fifths as long as

C. as four-fifths as long D. as four-fifths long as

析:B。A是B...的幾分之幾可表達為:A is +分數+as...as B。這種試題的備選答案形式相似,混淆度高,如果句型記憶不牢極易造成失分。

應對方法:熟悉分數、百分數、半數、倍數的表達方式和A是B的幾分之幾/百分之幾/一半/幾倍的表達方式,并增強其使用意識。
