      李建高

      一、考查基數(shù)詞的用法

      【真題】(2016年濟(jì)南卷) —How many hours do you sleep every night?

      —About ____ hours. From 9:00 p.m. to 6:00 a.m.

      A. nine B. nineteen

      C. ninth D. ninety

      【答案】A

      【解析】句意為:——你每晚睡幾個(gè)小時(shí)?——大約9個(gè)小時(shí)。從晚上9點(diǎn)到早上6點(diǎn)。基數(shù)詞用于表示事物的數(shù)量。由From 9:00 p.m. to 6:00 a.m.不難推算出睡眠時(shí)間為“9個(gè)小時(shí)”,空白處應(yīng)填基數(shù)詞nine。

      【溫馨提示】基數(shù)詞的構(gòu)成:

      (1)0~12為基本單詞;13~19為對(duì)應(yīng)的個(gè)位數(shù)單詞或變形后加-teen,如:16→sixteen。整十的基數(shù)詞(10除外)為其對(duì)應(yīng)個(gè)位數(shù)單詞或變形后加-ty,如:80→eighty。

      (2)兩位數(shù)基數(shù)詞的十位與個(gè)位數(shù)之間用連字符“-”連接,如:57→fifty-seven。

      (3)三位數(shù)的基數(shù)詞須在百位和十位(若無(wú)十位則和個(gè)位)之間用and連接,如:365→three hundred and sixty-five。

      (4)1000以上的基數(shù)詞從數(shù)字的右端向左端數(shù)起,每三位數(shù)后面加一個(gè)逗號(hào)。第一個(gè)逗號(hào)前的數(shù)為thousand,第二個(gè)逗號(hào)前的數(shù)為million,第三個(gè)逗號(hào)前的數(shù)為billion。兩個(gè)逗號(hào)之間最大的數(shù)為百位數(shù)。如:2,383,820,966→two billion three hundred and eighty-three million eight hundred and twenty thousand nine hundred and sixty-six。

      二、考查序數(shù)詞的用法

      【真題1】(2016年武威卷) July 1st of this year is the ____ birthday of the CPC (中國(guó)共產(chǎn)黨).

      A. ninety-five B. ninetieth-fifth

      C. ninetieth-five D. ninety-fifth

      【答案】D

      【解析】句意為:今年的7月1日是中國(guó)共產(chǎn)黨第95個(gè)生日。“第95個(gè)”用序數(shù)詞ninety-fifth表示,并且序數(shù)詞前面要加定冠詞the,表示順序。

      【溫馨提示】序數(shù)詞的構(gòu)成:

      (1) 除“第一”“第二”“第三”外,其他序數(shù)詞都是在基數(shù)詞后面加-th構(gòu)成,其中有些詞在拼寫上有細(xì)微的變化。如:fifth, eighth, ninth, twelfth, twentieth等。

      (2) 兩位數(shù)的詞,只需把個(gè)位數(shù)變?yōu)樾驍?shù)詞。如:第二十二→twenty-second。

      (3) 三位以上的詞,只需要把最后的兩位數(shù)變?yōu)樾驍?shù)詞。如:第九百九十九→nine hundred and ninety-ninth。

      另外,序數(shù)詞可以用縮寫形式來(lái)表示,如:“第一”“第二”“第三”的縮寫形式分別是1st, 2nd, 3rd;其他序數(shù)詞的縮寫形式是在阿拉伯?dāng)?shù)字后面加-th。

      【真題2】(2016年瀘州卷) On her ____ birthday, she got an iPad as a gift from her father.

      A. twelve B. twelfth

      C. the twelve D. the twelfth

      【答案】B

      【解析】句意為:在她12歲生日時(shí),她從父親那里得到一部iPad?!暗?2個(gè)生日”用序數(shù)詞twelfth表示,當(dāng)名詞前有限定詞(如形容詞性物主代詞或名詞所有格等)修飾時(shí),就不再用定冠詞the。

      【真題3】(2016年隨州卷) —If your parents wanted to have a ____ child, would you agree?

      —Of course. But they should make it in ____ years time.

      A. second; second B. two; two

      C. second; two D. two; second

      【答案】C

      【解析】句意為:——如果你的父母想再要一個(gè)孩子,你會(huì)同意嗎?——當(dāng)然。但他們應(yīng)該在兩年之后再要。當(dāng)序數(shù)詞前加不定冠詞a或an時(shí),意為“又一,再一”。

      三、考查hundreds / thousands / millions / billions of等的用法

      【真題1】(2016年淮安卷) More than two ____ trees are planted in our neighborhood every year.

      A. hundred B. hundreds

      C. hundreds of D. hundred of

      【答案】A

      【解析】句意為:每年在我們的街區(qū)栽種200多棵樹(shù)。當(dāng)hundred, thousand, million, billion等詞前面有基數(shù)詞修飾時(shí),要用單數(shù)形式。本題中hundred前面有基數(shù)詞two修飾,所以用單數(shù)形式,并且其后不接of。

      【真題2】(2016年安順卷) Unluckily, ____ people were killed in the earthquake.

      A. two thousands B. thousand of

      C. two thousands of D. thousands of

      【答案】D

      【解析】句意為:不幸的是,成千上萬(wàn)的人在這次地震中喪生。hundreds / thousands / millions / billions of意為“數(shù)百/千/百萬(wàn)/十億的”,前面不用基數(shù)詞,但可用many, several等詞修飾。本題中thousands of意為“成千上萬(wàn)的”。

      四、考查“基數(shù)詞+名詞(+形容詞)”構(gòu)成的復(fù)合形容詞

      【真題1】(2015年孝感卷) Last year, three hundred English teachers took part in the ____ English Training.

      A. two-month B. two-months

      C. two months D. two month

      【答案】A

      【解析】句意為:去年,300名英語(yǔ)老師參加了為期兩個(gè)月的英語(yǔ)培訓(xùn)。在“數(shù)詞+名詞(+形容詞)”構(gòu)成的復(fù)合形容詞中,詞與詞之間要用連字符“-”連接,并且名詞要用單數(shù)形式?!皟蓚€(gè)月的”是復(fù)合形容詞,表示為“two-month”。

      【真題2】(2016年連云港卷) —Yan Jiashuo, a ____ girl, has won the prize of International Master of Memory.

      —Wow, shes great, isnt she?

      A. ten-year-old B. ten-years-old

      【溫馨提示】分?jǐn)?shù)的構(gòu)成:

      表示“幾分之幾”,英語(yǔ)中常用基數(shù)詞做分子,序數(shù)詞做分母。當(dāng)分子是1時(shí),分母用單數(shù)形式;當(dāng)分子大于1時(shí),分母用復(fù)數(shù)形式。另外,表達(dá)“二分之一”,可用one half或a half。表達(dá)“四分之幾”,可用“基數(shù)詞+ quarter(s)”。

      【真題2】(2016年龍東卷) About ____ of the land ____ covered with trees and grass.

      A. three fifths; is B. three fifths; are

      【溫馨提示】“in ones + 逢十的基數(shù)詞復(fù)數(shù)”,表示“某人幾十歲”。

      七、考查編號(hào)的表達(dá)

      【真題】(2016年廣東卷) Please turn to page ____ and take a look at the picture on it.

      A. the eightieth B. eightieth
