第二课时语法知识词法（1） 一、名词 表示某一事物，有具体的和抽象的之分。分为可数名词和不可数名词。 强调：不可数名词都默认为单数，最好不要根据some、any、a lot of等词去作判断，以免受误导。 1、可数名词如何变“复数形式”： a．一般情况下，直接加-s，如：book-books, bag-bags, cat-cats, bed-beds ； 读音：清辅音后读[s]，浊辅音和元音后读[z]。 b．以s. x. sh. ch结尾，加-es，如：bus-buses, box-boxes, brush-brushes,watch-watches； 读音：[iz]。 c．以“辅音字母+y”结尾，变y为i, 再加-es，如：family-families, fly-flies ； 读音：[z]。 d．以“f或fe”结尾，变f或fe为v, 再加-es，如：knife-knives ；读音：[z]。e．以“o”结尾的词，分两种情况 1）有生命的+es 读音：[z] 如：mango-mangoes tomato-tomatoes hero-heroes 2) 无生命的+s 读音：[z] 如：photo-photos radio-radios f. 不规则名词复数：man-men, woman-women, policeman-policemen, policewoman-policewomen, snowman-snowmen, child-children, foot-feet, tooth-teeth, fish-fish, people-people, 2、不可数名词没有复数。 如果要计算不可数名词所表达的数量，就得在数词和不可数名词之间加上“量词+of”。
巧记英语序数词 英语中的数词分为基数词和序数词，而基数词和序数词的的变化学生常出现错误，在教学过程中我总结了以下口诀，学生们用起来就简单多了，并且还不会出错。 基变续，有规律，词尾加上th; 一二三，特殊记，词尾字母t,d,d(first,second,third); 八减t(eighth), 九去e (ninth)，f来把ve替 (five---fifth,twelve---twelfth); 单词ty作结尾，ty变成tie(twenty-twentieth); 若是碰到几十几，只变个位就可以(twenty-one----twenty-first). 序数词表顺序，一般需用定冠词。 基数词和序数词的练习题 一、写出下列词的序数词 1. one 2.two 3. six 4.five 5. nine 6.twelve 7.eight 8.twenty-one 二、写出下列单词的基数词 1.third 2.fourth 3.tenth 4.twentieth 5.nineteenth 6.thirty-first _ 三、根据句子意思填空。 1. Children’s Day（儿童节） is on the of June（六月）. 2. There are months（月）in a year(年). 3. Teacher’s Day(教师节) is on the of September（九月）. 4. Three plus(加) six is . 四、选择题

英语数词的用法 Revised as of 23 November 2020
英语数词用法详解 数词部分 ▲掌握分数、时间、日期的表达法。 【复习要点】 （一）基数词 基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。 1 one11 eleven100 a?hundred 2 two12 twelve20 twenty1000 a?thousand 3 three13 thirteen30 thirty1，000，000 a?million 4 four14 fourteen40 forty10，000，000 ten million 5 five15 fifteen50 fifty100，000，000 a?hundred million 6 six16 sixteen60 sixty1，000，000，000 a?billion 7 seven17 seventeen70 seventy 8 eight18 eighteen80 eighty 9 nine19 nineteen90 ninety 10 ten 说明： 1．13—19是由个位数加后缀-teen构成。注意其中13、15的拼写是thirteen和fifteen。
2．20—90由个位数加后缀-ty构成，注意其中20—50的拼写分别是twenty, thirty, forty?和fifty;80的拼写是eighty。 3．其它非整十的两位数21—99是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one。 4．101—999的基数词先写百位数，后加and再写十位数和个位数。如：691 six hundred and ninety-one。 5．1000以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和million（百万）来表达，其换算关系为：1万=10 thousand;1亿=100 million; 10亿=a thousand million=a billion。 6．多位数的读法： 1）1000以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million（百万），第三个间隔或逗号前是a thousand million或a billion(十亿)。 2）每隔三位分段以后就都成了101—999。读的时候十位数（或个位数）的前面一般要加and。如： 888，000，000读作：eight hundred and eighty-eight million。 基数词的用法： 1.基数词在句中的作用

A. hundred B. hundreds C. hundreds of D. hundred of 【答案】 A 【解析】【分析】句意：地震期间，校舍里大约有六百名学生。hundred，百，基数词，表示具体的数量，其前要用基数词；hundreds of +可数名词复数，表示不确定的数量，固定短语。空格前有基数词six，要用hundred，故答案选A。 【点评】考查基数词hundred的用法。注意hundreds不能单独使用，必须与of放在一起使用。 2．The number of the students in our school is about four __________. _______ of them are girls.

英语 ------ 数词 ▲掌握分数、时间、日期的表达法。 【复习要点 （一）基数词 基数词用来表示数目，或者说表示数量的词叫基数词。最基本的基数词如下表所示。 1 one11 eleven100 a hundred 2 two12 twelve20 twenty1000 a thousand 3 three13 thirteen30 thirty1， 000， 000 a million 4 four14 fourteen40 forty10， 000，000 ten million 5 five15 fifteen50 fifty100， 000，000 a hundred million 6 six16 sixteen60 sixty1， 000， 000， 000 a billion 7 seven17 seventeen70 seventy 8 eight18 eighteen80 eighty 9 nine19 nineteen90 ninety 10 ten 说明： 1． 13— 19 是由个位数加后缀-teen 构成。注意其中13、 15 的拼写是 thirteen 和 fifteen 。2． 20— 90 由个位数加后缀-ty 构成，注意其中20— 50 的拼写分别是twenty, thirty, forty 和fifty;80 的拼写是eighty 。 3 ．其它非整十的两位数21— 99是由整十位数加连字符“-”，再加个位数构成。如：81 eighty-one 。 4．101— 999 的基数词先写百位数，后加and 再写十位数和个位数。如：691 six hundred and ninety-one 。 5． 1000 以上的基数词先写千位数，后写百位数，再加and，最后写十位数和个位数。 如：5893 five thousand eight hundred and ninety-three 。在基数词中只有表示“百”、“千”的单位词，没有单独表示“万”、“亿”的单位词，而是用thousand（千）和 million （百万）来 表达，其换算关系为： 1 万 =10 thousand;1 亿 =100 million; 10亿=a thousand million=a billion。6．多位数的读法： 1） 1000 以上的多位数，要使用计数间隔或逗号“，”。即从个位起，每隔三位加一个间 隔或逗号。第一个间隔或逗号前是thousand（千），第二个间隔或逗号前是million （百万），第三个间隔或逗号前是 a thousand million 或 a billion( 十亿 )。 2）每隔三位分段以后就都成了101— 999。读的时候十位数（或个位数）的前面一般要 加 and。如： 888， 000，000 读作： eight hundred and eighty-eight million 。 基数词的用法： 1.基数词在句中的作用 基数词的作用相当于名词和形容词，在句中可作定语、主语、宾语（介宾）、表语、同
