◇ 101 one hundred and one
◇ 225 two hundred and twenty five

（3） 基数词的用法

hundred，thousand和million在合成数词中一般用单数形式，但是用来表示不定
数目时，用作复数形式。例：
◇ Hundreds of workers will go onstrike．
◇ Thousands of people are swimmingin the river．
此时 hundred，thousand等词前没有数词修饰，且通常其复数形式与of 连用。
序数词的构成与用法
（1） 序数词的构成
① 一般来说，是由相应的基数词加词尾th构成。例：
◇ four ＋ th → fourth ◇ six ＋ th → sixth
◇ seven ＋ th → seventh ◇ ten ＋ th → tenth
② 下面这些基数词在变为序数词时，有特殊的变化。例：
◇ one → first ◇ two → second ◇ three → third
◇ five → fifth ◇ eight → eighth ◇ nine → ninth
◇ twelve → twelfth
③ 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 → thirtieth
◇ forty → fortieth ◇ ninety → ninetieth
④ 两位或两位以上的基数词变成序数词时，仅将个位数变成序数词。例：
◇ twenty－one → twenty－first
◇ thirty－five → thirty－fifth
◇ a hundred andfifty－three → a hundred and fifty－third
（2） 序数词的用法
① 序数词在使用时，一般加上定冠词。例：
◇ the first book ◇ the second floor
◇ the third day ◇ the fourth week．
② 序数词在多数情况下都用作定语，有的也可以作表语、主语和宾语。例：
◇ The may 1st is Labour Day．
五月一日是劳动节。
◇ My room is on the second floor．
我的房间在二楼。
◇ The first is larger than the second． （主语）
第一个比第二个大。
◇ Read the book from the first．宾语）
从开头读这本书。
◇ You’ll be the sixth to write． （表语）
你将是第六个写的。
③ 序数词的前面可以加上不定冠词，用来表示“再一”，“又一”的意思。例：
◇ You may have a third try．
你可以第三次尝试。
（3） 时间表示法
① 时间都由基数词表示。例：
◇ It’s nine．
现在九点。
◇ It’s not five yet．
还不到五点。
有时后面要加o’clock，但在口语中通常省略。
② 几点几分表示法有两种形式。
A．倒读法：与汉语顺序不同，先读“分”后说点”。30分钟以内，用“分钟数”＋past ＋“钟点数”表示“几点过几分”，超过30分钟，用“分钟数”＋ to＋ “下一个钟点数”表示“差几分到几点”。15分钟也可以用a quarter，30分钟也可以用a half。例：
◇ 2：15 a quarter past two
◇ 2：45 a quarter to three
◇ 1：55 five to two
◇ 7：05 five past seven
◇ 5：35 thirty five past five
◇ 9：30 half past nine
只有指几点钟整时才用o’clock，如teno’clock，但不可以说seven past
ten o’clock．
B．顺读法：与汉语顺序相同，连用两个基数词，第一个表示“点钟”，第二个表示“分钟”。例：
◇ 5：40 five forty
◇ 2：30 two thirty
◇ 1：15 one fifteen
这时的15和30不能用a quater, a half代替。
（4） 日期表示法
① 年的读法：用基数词，分成两位一读。例：
◇ 1949 nineteen forty－nine
◇ 1840 eighteen forty
② 月份的名称要大写。例：
◇ January ◇ February ◇ March ◇ April
③ 日期用序数词表示，前面可加the，也可以省略。例：
◇ 5月4日 May （the） fourth
◇ 10月1日 October （the） first
④ 年、月、日的顺序：在英语中， 按月、日、年的顺序来读。例：
◇ 1949年10月1日 October （the） firstnineteen forty－nine
◇ 1999年5月1日 May （the） first nineteenninety－nine
表示在“在某年、在某月”用介词in，如in2000，in September，表示“在某日
”用介词on，如on July 8。
（5） 编号的读法
① 表示“第几课（部分，章或节）”时，用序数词时，前面一定要加冠词；用基数词时，不用冠词，但
语序与汉语相反。例：
◇ lesson one → the first lesson
◇ part three → the third part
② 当数字较长时，通常用基数词。例：
◇ 第219页 page 219 （two one nine）
◇ 第306号房间 room 306 （three o six）
◇ 第六路公共汽车 bus number six
◇ 电话号码 885316 telephone number 885316 （eight eight
five three one six）
（6） 倍数的用法
① The train arrived half an hour late．
火车晚到了半个小时。
half 是形容词。
② He has three times as many books as I have．
他的书有我的三倍多。
“～的几倍”的说法，两倍用twice，注意表示倍数的词在句中的位置。
