一、考查基数词的表达法
三位数以内基数词的表达法:个位、十位之间用连字符,十位、百位之间用and。 例如:
(2007山东济南市) 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
【解题点拨】 本题考查基数词的表达法。 hundred前面有数词时,即使这个数词大于1,也用hundred,不用hundreds,且百位与十位之间用and连接。故答案为A。
二、考查基数词的用法
1. 表示街道、建筑物、学校的序号时,可用“名词(首字母大写) + 基数词(英语首字母也大写)”,也可用“the + 序数词 + 名词”。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
【解题点拨】 此题考查基数词表顺序时的特殊用法。基数词一般放在名词之后,且首字母要大写。故答案为D。
2. 表示时间时,整点钟用“基数词 + oclock”表示,几点过几分用“分钟数 + past + 钟点数”,几点差几分用“分钟数 + to + 下一钟点数”。 例如:
(2007黑龙江哈尔滨市) —Its 7:45.
—Yes,its____ .
A. a quarter past seven B. a quarter to eight
C. fifteen past seven oclock D. seven fifteen oclock
【解题点拨】 此题考查时间表达法。表示钟点过半要用“所差的分钟数 + to + 下一个钟点数”。故答案为B。
三、考查基数词的复数形式
ten,hundred,thousand,million,billion等词单独与of短语搭配使用时,可用其复数形式。例如:
(2007安徽芜湖市) —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
【解题点拨】 句中空白处的数词后面是表示复数意义的名词people,所以该空应该填Millions of。 故答案为B。
四、考查分数的构成形式
分数词的构成方法:分子用基数词,分母用序数词。分子大于1时,表示分母的序数词后面加-s。 另外还要注意下列特殊的表达形式: 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
【解题点拨】 此题考查分数的表达法。题中的分子four大于1,表示分母的序数词fifth后面应加“-s”。 故答案为B。
五、考查序数词的构成及用法
1. 序数词前面加定冠词表示“第几个人或物”,而序数词前面加不定冠词,则有“再一、又一”的含义。例如:
(2007四川广元市) —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
【解题点拨】 表示“他的9岁生日”,其中的9应该用序数词表示。故答案为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
【解题点拨】 表示“第十层”应该用the tenth floor。 故答案为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. ×
【解题点拨】 两把尺子都断了,我还要再买一把。言外之意,“我要买两把尺子之外的第三把尺子”。所以答案为B。
2. 序数词还可以用在形容词最高级前面作修饰语。例如:
(2007山东济南市) He is____ in our class.
A. the fourth tallest B. fourth tallest
C. four tallest D. the four tallest
【解题点拨】 句意为“他在我们班是第四个个子最高的同学”,句中的in our class是比较范围,与之相搭配的应为“the fourth tallest”。 故答案为A。
六、考查与数词有关的词语
1. 基数词可与表示度量单位的词连用。其词序常为“数词 + 量词 + 形容词”。例如:
(2007河南郑州市) The river is more than____ .
A. twenty metre wide B. twenty metres wide
C. twenty metre of wide D. wide of twenty metre
【解题点拨】 表示物体或人体的“宽”、“长”、“深”时,应该用“基数词 + 量词 + 形容词”。基数词超过“1”时,量词为复数形式。故答案为B。
2. other,more置于数词之后,another置于数词之前,都表示“还;再”之意。例如:
(2006山东烟台市) —Do you have enough students to carry the boxes?
—No,I think we need____ .
A. anotherB. two others
C. more two D. two more
【解题点拨】 another后面应接所修饰的名词或代词,others不可位于数词之后,more可位于数词之后。故答案为D。
3. 表示“半个……”,可用 “half a/an + 可数名词单数”。表示“几个半……”,可用“基数词 + and a half + 复数名词”或“基数词 + 可数名词(单、复)数 + and a half”。 例如:
(2007湖北武汉市) Do you want to buy____ pork?
A. half kilo B. half a kilo
C. a kilo half D. a half kilo
【解题点拨】 half a kilo意为“半公斤”。故答案为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
【解题点拨】 一个半小时的表达方式为one and a half hours或one hour and a half。 故答案为B。
