    數(shù)詞難點(diǎn)揭秘

    發(fā)布時(shí)間:2016-5-1 編輯:互聯(lián)網(wǎng) 手機(jī)版

    作者:郝昌明

    一、數(shù)詞竟然有復(fù)數(shù),平時(shí)學(xué)習(xí)不注意

    難點(diǎn)介紹:

    對(duì)數(shù)詞的掌握不少同學(xué)建立在基數(shù)詞、序數(shù)詞及其轉(zhuǎn)換上,很少有人會(huì)想到數(shù)詞的復(fù)數(shù)形式,結(jié)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(yīng)用in the 90s短語;第二空表"在他們五十多歲時(shí)",應(yīng)用 in their fifties短語,但不少同學(xué)不了解數(shù)詞的復(fù)數(shù)形式,結(jié)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(yīng)表達(dá)為by twos and threes,但有些同學(xué)因?qū)?shù)詞的復(fù)數(shù)形式缺乏了解而造成解題錯(cuò)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(xué)因?qū)@種語法現(xiàn)象知之甚少而造成解題錯(cuò)誤。

    應(yīng)對(duì)方法:重視數(shù)詞的復(fù)數(shù)形式,熟悉數(shù)詞的復(fù)數(shù)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(shí);in the 1980's/1980s在二十世紀(jì)八十年代。

    二、特殊數(shù)詞記不住,考試難免會(huì)出錯(cuò)

    難點(diǎn)介紹:

    不少同學(xué)對(duì)基數(shù)詞、序數(shù)詞非常熟悉,但對(duì)分?jǐn)?shù)、百分?jǐn)?shù)、半數(shù)、倍數(shù)等特殊數(shù)詞形式不太了解,即使有所接觸也因其形式復(fù)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(shù)的表達(dá)方法,其結(jié)構(gòu)為:A... times as 形容詞/副詞原級(jí)as B,不少考生沒記住這個(gè)結(jié)構(gòu),結(jié)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?jǐn)?shù)的表達(dá)方式為:先講分子,再講分母,分子用基數(shù)詞,分母用序數(shù)詞,分子大于1時(shí)分母用序數(shù)詞的復(fù)數(shù)形式,中間加連字符號(hào)。分?jǐn)?shù)應(yīng)放在所修飾的名詞前面。不少考生對(duì)分?jǐn)?shù)構(gòu)成及其用法特點(diǎn)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(dá)為:A is half as...as B。但如果記不住這一結(jié)構(gòu),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(dá)為:A is +分?jǐn)?shù)+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(yīng)對(duì)方法:熟悉分?jǐn)?shù)、百分?jǐn)?shù)、半數(shù)、倍數(shù)的表達(dá)方式和A是B的幾分之幾/百分之幾/一半/幾倍的表達(dá)方式,并增強(qiáng)其使用意識(shí)。
