谈谈中考中数词的考点

吴　静

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。
