一、考查基數詞的表達法
三位數以內基數詞的表達法:個位、十位之間用連字符,十位、百位之間用and。 例如:
(2007山東濟南市) The road is over____ metres long.
A. six hundred and fifty-two B. six hundreds and fifty-two
C. six hundred,fifty-two D. six hundred,fifty and two
【解題點撥】 本題考查基數詞的表達法。 hundred前面有數詞時,即使這個數詞大于1,也用hundred,不用hundreds,且百位與十位之間用and連接。故答案為A。
二、考查基數詞的用法
1. 表示街道、建筑物、學校的序號時,可用“名詞(首字母大寫) + 基數詞(英語首字母也大寫)”,也可用“the + 序數詞 + 名詞”。例如:
(2007浙江省) —Where is the head teacher?
—Maybe he is in____ .
A. Two Room B. the Two Room
C. Rooms two D. Room Two
【解題點撥】 此題考查基數詞表順序時的特殊用法。基數詞一般放在名詞之后,且首字母要大寫。故答案為D。
2. 表示時間時,整點鐘用“基數詞 + oclock”表示,幾點過幾分用“分鐘數 + past + 鐘點數”,幾點差幾分用“分鐘數 + to + 下一鐘點數”。 例如:
(2007黑龍江哈爾濱市) —Its 7:45.
—Yes,its____ .
A. a quarter past seven B. a quarter to eight
C. fifteen past seven oclock D. seven fifteen oclock
【解題點撥】 此題考查時間表達法。表示鐘點過半要用“所差的分鐘數 + to + 下一個鐘點數”。故答案為B。
三、考查基數詞的復數形式
ten,hundred,thousand,million,billion等詞單獨與of短語搭配使用時,可用其復數形式。例如:
(2007安徽蕪湖市) —How many people will come to Beijing next year?
—Its hard to say.____ people,I think.
A. Million of B. Millions of
C. Three millions D. Three millions of
【解題點撥】 句中空白處的數詞后面是表示復數意義的名詞people,所以該空應該填Millions of。 故答案為B。
四、考查分數的構成形式
分數詞的構成方法:分子用基數詞,分母用序數詞。分子大于1時,表示分母的序數詞后面加-s。 另外還要注意下列特殊的表達形式: a half = one second (1/2),one quarter = one fourth (1/4),three quarters = three fourths (3/4)。例如:
(2007北京市) About____ of the books in our school library are written in Chinese.
A. four fifth B. four fifths
C. fourth fifths D. fourths fifth
【解題點撥】 此題考查分數的表達法。題中的分子four大于1,表示分母的序數詞fifth后面應加“-s”。 故答案為B。
五、考查序數詞的構成及用法
1. 序數詞前面加定冠詞表示“第幾個人或物”,而序數詞前面加不定冠詞,則有“再一、又一”的含義。例如:
(2007四川廣元市) —Sandy,our son is 9 years old tomorrow.
—Oh,yes. We should have a party for his____ birthday.
A. nine B. ninth C. the ninth
【解題點撥】 表示“他的9歲生日”,其中的9應該用序數詞表示。故答案為B。
(2007浙江衢州市) —Which floor does Mr Hu live on?
—He lives on____ floor.
A. tenth B. the tenth C. ten D. the ten
【解題點撥】 表示“第十層”應該用the tenth floor。 故答案為B。
(2007天津市) Both of the two rulers are broken. I want to buy a____ one.
A. three B. third C. fourth D. ×
【解題點撥】 兩把尺子都斷了,我還要再買一把。言外之意,“我要買兩把尺子之外的第三把尺子”。所以答案為B。
2. 序數詞還可以用在形容詞最高級前面作修飾語。例如:
(2007山東濟南市) He is____ in our class.
A. the fourth tallest B. fourth tallest
C. four tallest D. the four tallest
【解題點撥】 句意為“他在我們班是第四個個子最高的同學”,句中的in our class是比較范圍,與之相搭配的應為“the fourth tallest”。 故答案為A。
六、考查與數詞有關的詞語
1. 基數詞可與表示度量單位的詞連用。其詞序常為“數詞 + 量詞 + 形容詞”。例如:
(2007河南鄭州市) The river is more than____ .
A. twenty metre wide B. twenty metres wide
C. twenty metre of wide D. wide of twenty metre
【解題點撥】 表示物體或人體的“寬”、“長”、“深”時,應該用“基數詞 + 量詞 + 形容詞”。基數詞超過“1”時,量詞為復數形式。故答案為B。
2. other,more置于數詞之后,another置于數詞之前,都表示“還;再”之意。例如:
(2006山東煙臺市) —Do you have enough students to carry the boxes?
—No,I think we need____ .
A. anotherB. two others
C. more two D. two more
【解題點撥】 another后面應接所修飾的名詞或代詞,others不可位于數詞之后,more可位于數詞之后。故答案為D。
3. 表示“半個……”,可用 “half a/an + 可數名詞單數”。表示“幾個半……”,可用“基數詞 + and a half + 復數名詞”或“基數詞 + 可數名詞(單、復)數 + and a half”。 例如:
(2007湖北武漢市) Do you want to buy____ pork?
A. half kilo B. half a kilo
C. a kilo half D. a half kilo
【解題點撥】 half a kilo意為“半公斤”。故答案為B。
(2006浙江省) It took me____ to find out the key to the drawer.
A. one and half hours B. one and a half hours
C. one and a half hour D. one and half hour
【解題點撥】 一個半小時的表達方式為one and a half hours或one hour and a half。 故答案為B。
