课件39张PPT。专题 5　数词专题 5　数词┃考点直击 ┃●1　数词表示编号
在通常情况下，表示年级、班级、排、房间、课等的编号要用基数词，且基数词要在名词后，表示“年级”等名词的首字母要大写；若基数词用英语表示，其首字母也要大写。若要用序数词表示，则序数词前必须加the。如： Lesson One/the first lesson 第1课，Room 306 306号房间，Row Four/the fourth row第4排，Class Three, Grade Nine 九年级三班。专题 5　数词●2　基数词的拼写
1. 0—12单独记。如： zero, one, two, three。
2. 13—19词尾都是-teen。如： fourteen, seventeen，但13—thirteen, 15—fifteen, 18—eighteen需要特殊记。
3. 20, 30, 40等整数的基数词均以-ty结尾。如： 20—twenty, 30—thirty, 40—forty, 50—fifty, 80—eighty。
4. “几十几”要加连字符“-”。如： 48—forty-eight, 97—ninety-seven。专题 5　数词5. “几百几十”或者“几百几十几”在百后加and。如： 156—one hundred and fifty-six, 509—five hundred and nine。
6. 四位数或者四位数以上的基数词书写时从右往左每三位加一个逗号，第一个逗号前为thousand(千)，第二个逗号前为million(百万)，第三个逗号前为billion(十亿)。如： 3，610＝three thousand six hundred and ten; 94，295＝ninety-four thousand two hundred and ninety-five; 274，350＝two hundred and seventy-four thousand three hundred and fifty。专题 5　数词●3　确数和概数的表达
“基数词＋hundred/thousand/million/billion”表示确定数目；表达不确定数目，即数百、数千等时，要用“hundreds/thousands/millions/billions of ＋名词复数”形式，其前可用many, some, several等修饰。 如：
____________ students 五百名学生
many/several ____________ students 数千名学生five hundred thousands of 专题 5　数词●4　以-ty结尾的基数词复数的意义
从20至90以-ty结尾的基数词表示年代或岁数时，以复数形式出现。如：
in the 1990s/in the 1990's在二十世纪九十年代
in her forties在她四十多岁时专题 5　数词●5　序数词的构成与功能
序数词除用来表示编号外，还可用来表示事物的先后顺序，多与定冠词、物主代词或名词所有格连用。注意下列数词的拼写与转换： one—first, two—________， three—third, five—fifth, eight—eighth, nine—________， twelve—twelfth, forty—________。
　　　　　second ninth fortieth 专题 5　数词记忆口诀
基变序，有规律，词尾加上th。
一二三，特殊记，词尾字母t d d。
八减t, 九减e, f要把ve替。
ty把 y 变成i, 记住th 前有个e。专题 5　数词[注意] 另外，表示第几十几时，用几十的基数词形式加上连字符“-”和个位序数词形式一起表示；表示第一百以上的多位序数词时，由基数词的形式变结尾部分为序数词形式来表示。如： fifty-second第五十二，seventy-sixth第七十六，eighty-ninth第八十九，two hundred and thirty-first第二百三十一。专题 5　数词●6　不定冠词a/an与序数词连用
序数词除了与定冠词、物主代词或名词所有格等连用表示顺序外，还可与a/an连用，意为“再一，又一”，相当于another。如：
Then they had a second child—a son.
然后他们又有了一个孩子——一个儿子。专题 5　数词●7　分数的用法
1．分数的构成： 分子用基数词，分母用序数词；若分子大于1，分母加-s。如： 1/3—a(one) third, 2/3—two thirds。
[注意] 1/2—one half或a half(但不说one second)，3/4—three quarters/three fourths。
2．“分数＋名词”作主语时，谓语动词的单复数形式应由后面名词的数决定。后面的名词为可数名词复数时，谓语动词用复数形式；为不可数名词或可数名词单数时，谓语动词用单数形式。如：专题 5　数词Three fifths of the work ________ hard to finish.
五分之三的工作很难完成。
Three fifths of the students in our class ________League members.
我们班五分之三的学生是共青团员。
[注意] 数词作主语时，谓语动词多使用单数形式。如：
What's two and/plus three？二加三等于几？is are 专题 5　数词●8　时间表达法
1．整点钟： 基数词＋o'clock
2．非整点时间： 顺读(先读点钟，再读分钟)或逆读
(1)当分钟数≤30时，可用“分钟＋past＋点钟”表示。如： twenty-five past seven 7：25。
(2)当分钟数＞30时，可用“(60－分钟数)＋to＋(点钟＋1)”表示。如： twenty-five to eight 7：35。
[注意] 15 minutes＝a quarter, 30 minutes＝half an hour。专题 5　数词●9　日期表达法
其顺序为“月＋日＋年”，日和年之间需用逗号隔开，也可以用“日＋月＋年”来表示。如：
August 2nd, 2003 2003年8月2日
10th May, 2003 2003年5月10日专题 5　数词●10　特殊表达
