小学英语数词_小学英语词法 | 数词、量词的使用详解及练习小学英语数词数词和量词是小学英语必须掌握的一类知识点,相信大家对数词量词并不陌生,但是不少同学还处懵懂的阶段。
那么如何准确无误的拿到数词和量词的分值呢,我们今天一起来学习一下吧!最基本的基数词一、基数词的写法:21~99的两位数,十位与个位之间用连字符。
例:21twenty - one32thirty - two99ninety – nine注意:数字“0”可以读作“zero”,也可以读作字母“o”。

例:one—— first two —— secondthree —— third five —— fiftheight —— eighth nine —— ninthtwelve —— twelfth3. 十位整数序数词的构成方法是将基数词的词 y 变成 i,然后再加 eth.例:twenty —— twentieth thirty —— thirtiethforty —— fortieth ninety —— ninetieth4. 两位或两位以上的基数词变为序数词时,仅将个位数变成序数词。
例:twenty –one —— twenty- firstthirty-five —— thirty-fiftha hundred and fifty-three —— a hundred and fifty- third基数词变序数词的口诀基变序,有规律,词尾加上th;一、二、三,单独记,结尾字母 t, d, d;八去t,九去e,ve要用f替;整十基数变序数,ty 将 y 变成 i ; th 前面有个 e;要是遇到几十几,前用基来后用序。

英语数词的详细讲解
英语数词的详细讲解英语数词是用来表示数量或顺序的词,主要分为基数词(cardinal numbers)和序数词(ordinal numbers)两大类。
以下是关于英语数词的详细讲解:一、基数词基数词用于表示事物的数量。
从1到12的基数词分别是:one,two,three,four,five,six,seven,eight,nine,ten,eleven,twelve。
从13开始,基数词的构成遵循一定的规律:在十位数词后面加“-teen”构成13至19的基数词(如thirteen,fifteen);在十位数词后面加“-ty”构成20至90的基数词(如twenty,forty,eighty);而100以上的基数词则是在百位数词后面加“hundred”(如one hundred,two hundred)。
二、序数词序数词用于表示事物的顺序。
序数词在构成上通常在基数词后面加“-th”,但也有例外。
例如:first,second,third,fifth,eighth,ninth,twelfth等。
对于整十的序数词,通常将个位数变为序数词(如twentieth,thirtieth,fortieth等)。
对于百位、千位等更高的序数词,则在相应的基数词后面加“-th”(如one hundredth,one thousandth)。
三、数词的用法用作定语:数词可以用作定语,修饰名词。
例如:“a three-story building”(一座三层楼)中的“three-story”就是数词作定语。
用作表语:数词也可以用作表语,表示数量或顺序。
例如:“She is the first to arrive.”(她是第一个到达的。
)中的“first”就是数词作表语。
用作主语或宾语:数词还可以用作主语或宾语。
例如:“Three plus five is eight.”(三加五等于八。
)中的“three”和“five”就是数词作主语,“eight”是数词作宾语。
小学英语数词及专项训练
小学英语数词及专项训练(总5页)小学英语数词及专项训练一、数词的分类:基数词和序数词。
基数用于表示数量多少,而基数词用于表示次序,常在日期中出现。
区别:基数词前面没有“the”;序数词前一定要有“the”。
1、超过二十以上的两位数需要在个位和十位之间加上“-”。
如:21 twenty-one2、用基数词来修饰可数名词时,一定别忘了它的复数形式。
如:十八个男孩 eighteen boys3、用基数词修饰不可数名词时,如是复数,变它的量词为复数。
如:两碗米饭 two bowls of rice4、序数词一般加“th”,特殊的有:first, second, third, fifth, eighth, ninth, twelfth;二十及二十以外的整十:twentieth, thirtieth, fortieth…“第几十几”:前面整十不变,后面“几”改为序数词。
如:88 eighty-eighth巧记基数词和序数词:1,2,3,特殊记,加th从4起; 8少t,9去e,逢5逢12ve变f;20~90,y要变ie;若是几十几,前基后序别倒位.二、数词的表示方法:三、数词的用法1. 章节、页数的读法第一章:the first chapter ; Chapter One第二节:the second section ; Section Two第三课:the third lesson ; Lesson Three第463页:page four six three第2564页:page two five six four或twenty-five sixty-four注意:如果页码的数字较长,通常用基数词。
2. 房间、门牌、电话号码的读法第305房间:Room three o(零)five长安街76号:seventy-six Chang'an Street电话号码:204-2244:telephone number two o(零) four two two(double two) four four十一路公共汽车:Bus(No.) eleven3. 年代、日期、时刻的读法(1)年份是四位数字时,各分成二位来读,eg. 公元1995年:1995(=nineteen ninety-five)(2)日期使用一般的序数词来读取eg. 5月10日:May 10th(=May tenth)(3)时刻通常用基数词来读eg. 8点45分:8: 45(=eight forty-five)(4)年代表示法:eg. 二十世纪九十年代:1990's nineteen nineties4. hundred, thousand, million用法:hundred, thousand, million前面有具体数字,要用单数形式,但如果它们后面有of,那它们要用复数形式,同时,前面不能再加具体的数目。
