中考英语 重难考点解疑（三年真题+两年模拟）第五讲 数词（原卷版 ）

第五讲数词考点扫描☆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,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“「'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---fourth②一，二，三特殊记，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-theight—eighth,nine—ninth,five-fifth,twelve一twelfth④以ty结尾的整十数，改y为ie,再加-th.twenty-twentieththirty-thirtiethtwenty-twentieththirty-thirtiethforty---fortiethfifty---fiftiethforty---fortiethfifty---fiftiethsixty-sixtiethseventy-seventiethsixty-sixtiethseventy-seventietheighty—eightiethninetyeighty—eightiethninety——ninetieth⑤几百几，几十几也容易，只需个位变为序。.序数词的用法序数词的用法：无论序数词的数字有多大，在数量上都只是力”，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二即：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。f。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ando以上用法要记住，用时千万莫大意。例1：Therearemonthsinayear.Decemberisthemonthofayear.A.twelve;twelveB.twelfth;twelfthC.twelve;twelfthD.twelfth;twelve【解析】考查基数词与序数词。句意：一年中有个月，12月是第个月。第一空后是months,表示个数，用基数词；第二空表示“第十二个月”，用序数词，故选C。【答案】C高频考点剖析二：序数词的用法.序数词前要加定冠词the,若序数词前有形容词性物主代词或名词所有格时省略theoBillismyfirstpenpal.比尔是我的第一个笔友。.序数词前加a/an表示“又一，再一EventhoughtheBrownshavethreechildren,theystillwantafourthone.尽管布朗夫妇已有三个孩子，可他们还想再要一个。典例2)Hehasfailedtimes,buthewon'tgiveupachance.A.third,fourB.three,fourth
