数词（专项训练）-2024-2025学年人教PEP版英语六年级下册

pep人教版小学英语数词专项训练 概念 数词主要包括基数词和序数词。基数词用于表示数量，如one、two、three等；而序数词用于表示顺序，如first、second、third等。无论是描述物品数量、表达时间、还是讲述年龄等，都离不开数词的运用。数词的分类 数词主要分为基数词和序数词两大类。 数词的表达方式 1.基数词 1 - 12 的基数词为独立单词 one（1）、two（2）、three（3）、four（4）、five（5）、six（6）、seven（7）、eight（8）、nine（9）、ten（10）、eleven（11）、twelve（12） 13 - 19 的基数词，一般以-teen结尾 thirteen（13）、fourteen（14）、fifteen（15）、sixteen（16）、seventeen（17）、eighteen（18）、nineteen（19） 注意： thirteen、fifteen 的拼写稍有不规则 20 - 90 整十数，以-ty结尾 twenty（20）、thirty（30）、forty（40）、fifty（50）、sixty（60）、seventy（70）、eighty（80）、ninety（90） 注意：forty 的拼写需特别注意，不是 fourty，这也是常见易错点。 21 - 99 的非整十数：先说几十，再说几，中间用“-”连接。如： twenty - one（21）、thirty - five（35）、forty - eight（48）等 拓展 100 及以上 one hundred（100），百位与十位（或个位）之间用 and 连接，如：one hundred and twenty - three（123） 2.序数词 序数词是用来表示顺序的数词，常与定冠词the连用。 1 - 3 的序数词 first（1st，第一）、second（2nd，第二）、third（3rd，第三） 4 - 19的序数词 通常在基数词后加-th，特殊的有:fifth（5th,第五），需将ve变为f再加-th;eighth（8th,第八),直接加-h；ninth（9th，第九），去掉e加-th；twelfth（12th，第十二），把ve变为f再加-th。 20及以上的整十数序数词 将词尾的-y变为-ie，再加-th。如： twentieth（20th，第二十）、thirtieth（30th，第三十）等。 非整十数的序数词 十位数用基数词，个位数用序数词，中间用连字符“-”连接。如：twenty-first（21st，第二十一）、thirty-second（32nd，第三十二）等。 数词的用法 1.表示数量 基数词最基本的用法就是用来表示人或事物的数量。例如： I have three apples.（我有三个苹果。） 2.表示年龄 用“基数词+ year(s) old”来表达年龄，当年龄大于 1 岁时，year 要用复数形式。如： I'm ten years old.（我十岁了。） My little sister is three years old.（我的小妹妹三岁了。） 3.表示日期 在英语里，表达日期要用序数词。先说月份，再说日期，日期要用序数词的缩写形式（除了 1st、2nd、3rd 外，其余通常以-th结尾），最后说年份。如： It's February 13th, 2025.（今天是2025年2月13日。） 4.表示时间 整点：用“基数词 + o'clock”，o'clock 可省略。如：It's six (o'clock).（六点了。） 非整点：先说小时数，再说分钟数，也可以借助介词 past（分钟数小于等于 30）或 to（分钟数大于 30）连接。如： It's half past seven.（七点半。）这里的 half 表示“一半”，即 30 分钟。 It's ten to eight.（七点五十。）意思是“差十分八点”，to 后面接即将到达的整点小时数。 拓展：当分钟数是 15 时，可用 a quarter past（表示“过一刻”）；分钟数是 45 时，可用 a quarter to（表示“差一刻”），如：It's a quarter past three.（三点一刻。）；It's a quarter to six.（五点四十五。） 5.表示顺序 序数词用于表示事物的排列顺序，常与定冠词the连用。如： He is the first one to come to school.（他是第一个到学校的。） 习题巩固 一、写出下列基数词对应的序数词。 1.one __________ 2.two __________ 3.three __________ 4.four __________ 5.five __________ 6.eight __________ 7.nine __________ 8.twelve __________ 9.twenty __________ 10.thirty - one __________ 二、写出下列序数词对应的基数词。 1.first __________ 2.second __________ 3.third __________ 4.fifth __________ 5.eighth __________ 6.ninth __________ 7.twelfth __________ 8.twentieth __________ 9.twenty - fifth __________ 10.thirty - second __________ 三、单项选择。 1.There are ______ days in a week.
