专题五 数词的主要命题点
考点扫描☆聚焦中考
数词是中考的常考点也是必考点，主要考查基数词、序数词、概数词以及分数的表达。
高频考点一：基数词的用法
1.基数词：表示数量多少的数词。2.序数词：表示顺序的数词
注意：
基数词的用法：用于修饰可数名词，除“1”之外名词都要用复数。
高频考点二：序数词的用法
基数词变序数词口诀:基变序，有规律，
①一般情况直接加-th,如:four---fourth
②一，二，三特殊记，词尾t , d , d .（ one-- first， two-- second， three-- third）
③8去t , 9去e ,ve要用f来代替（five ,twelve 是两兄弟）之后再加-th
eight--eighth， nine-- ninth，five--fifth， twelve→twelfth
④以ty 结尾的整十数，改y为 ie,再加-th.
twenty---twentieth thirty---thirtieth
forty---fortieth fifty---fiftieth
sixty---sixtieth seventy---seventieth
eighty---eightieth ninety----ninetieth
⑤几百几，几十几也容易，只需个位变为序。
2.序数词的用法
序数词的用法：无论序数词的数字有多大,在数量上都只是“1”，所以序数词只能用于修饰单数可数名词。其前必须加定冠词the, 除非有one’s.即：总有这样的标志。the/one’s+序数词+单数名词
高频考点三：分数、百分数的表达及做主语的用法
分数的表达法：分数由基数词和序数词合成。分子用基数词，分母用序数词。分子是1 时，分母用单数形式；分子大于1时，分母用复数形式。
百分数的表达法：百分数由基数词+percent表示。
分数和百分数跟名词做主语，谓语动词的形式由后面的名词决定。
高频考点四：hundred、thousand、million的用法
当这些词与具体数字连用时，习惯上用单数，而且也不后接介词of。当这些词不与具体数字连用，而是表示不确定的泛指数时，则不仅要要用复数，而且要后接介词of，然后才能接名词。
考点剖析☆名师点拨
高频考点剖析一：基数词的用法
数词是表示数量多少或顺序先后的词,数词可以分为基数词和序数词。
100以内的基数词基数词不难记,找清规律很容易,十二以内词各异,十三数到十九,teen莫忘记。二十、三十……至九十,尾巴要加ty。要说“几十几”,中间“-”别丢弃。
若说几百几十几,百位十位用and。以上用法要记住,用时千万莫大意。
典例1：(2018来宾)There are ________ months in a year. December is the ________ month of a year.
A．twelve; twelve B．twelfth; twelfth C．twelve; twelfth D．twelfth; twelve

1.分数的表达
(1)分子用基数词,分母用序数词;如果分子大于1,分母要用复数形式。
1/6 one sixth 3/4 three fourths 4/5 four fifths
(2)在英语中,“四分之一”常表示为a quarter;“四分之三”表示为three quarters;“二分之一”表示为a half。
2.分数的用法
“分数+of+限定词+名词复数”作主语时,谓语动词应用复数形式;
“分数+of+限定词+不可数名词/名词单数”作主语时,谓语动词常用单数形式。

1.one 和 two除了变序数词first ，second 还可以变成次数once一次, twice两次
2.序数词在使用时，通常前面要加定冠词the，除非有one's,如果序数词前面有不定冠词a/an时，则表示“再一”，“又一”。
如：I have two apples already, but I want a third apple.
●3.“基数词+more+名词”或“another+基数词+名词”表示在原来的基础上增加的数量。意为“又…”“再…”
如：two more apples=another two apples
●4.“基数词-单数名词”相当于复合形容词，作名词的定语，用于表示时间，距离等。如：two-hour walk=two hours' walk
●5.hundred百,thousand千, million百万. billion十亿等的用法：简单记为：等的用法：简单记为：
