五、英语小数读法
1)
不满
“1”
的小数的读法
小数 点读做
point
,小数点左边的零读做
naught(
英
)
或
zero
(美),也可不读。小数点右
边的小数部分按个位基数词依次读出。在小 数点后遇到零时,多读做字母
O
的音,例如:
a)0.3: naught/zero point three; point three
b)0.125: naught/zero point one two five; point one two five
c)0.008%: naught/zero point O O eight percent
2)
整数带小数的读法
小数点左边的整数部分按整数 读法或按个位基数词依次读出。
小数点右边的小数部分按个
位基数词依次读出。在小数点后遇到 零时,可读做
naught/zero,
也可以读做字母
O
的音,
例 如:
a)5.02: five point naught/zero two; five point O two
b)8.004: eight point naught naught/zero zero four; eight point O O four
c)17.69%: seventeen point six nine percent
d)33.33……:thirty
-three point three recurring
3)
万位和亿位以上整数带小数的读法
汉语里有万位和亿位以上整数带小数的写法或读法。英语里没有相应的表示
“
万
”
或
“
亿
”
的
单词。
译成英语时,< br>先将万理解为十个千,将亿理解为一百个百万。然后将小数点左边的整
数部分和小数点右边的小数 部分做相应的变化,例如:
a)5.3
万
: 53,000 fifty-three thousand
b)723.64
万
: 7,236,400 seven million, two hundred and thirty-six thousand , four
hundred
c)17.09
亿:
1,709,000,000 one point seven O nine billion; one billion, seven hundred and
nine million
六、分数
1
)表示分数时 ,分子要用基数词,分母用序数词。如果分子大于
1
,分母必须用复数形式:
1
/
3→a
(
one
)
third
2
/
3→two thirds
1
/
4→a
(
one
)
quarter
(或
fourth)
3
/
7→three sevenths
< br>1
/
2→
应读作
a
(
one
)
ha lf
*比较复杂的分数如:
24
/
789
,多读作
twenty four over seven hundred and eighty nine
。
小数
2
)表示小数时 ,小数点前面的基数词和前面讲的基数词的读法相同;小数点后的数字则必
须一一读出:
0
.
0089→
(
zero
/
naught
)
point zero zero eight nine
1
.
36→one point three six
3
)百分数
百分数由
percent
表示,百分号%读作
percent
,应用时常与
by
连用。
0
.
68
%
→zero point six eight percent
6
%
→six percent
369
%
→three hundred and sixty nine percent
The output of steel went up by 20 percent
.钢产量增长
20
%。
The price of cotton was reduced by 20 percent
.棉花的价格下降了
20
%。
The loss of water has been reduced to less than 30 percent
.水的损耗减少到
30
%
以下
七、年份
关于四位数年份的读法有下列几种情形:
1
)一般情况下,将表示年份的四个数字按前后分为两组,每 一组的数字都按基数词来
读。例如:
1865
年读作
eighteen sixty-five
1998
年读作
nineteen ninety-eight
2
)如果前两个数字为非
“
零< br>”
数字,后两位数分别为
“
零
”
,则先读出前两位数,然后将 后
面的两个
“
零
”
读为
hundred
。例如:
1900
年读作
nineteen hundred
1800
年读作
eighteen hundred
3
)第三个数字为
“
零
”
(其他数字不是
“
零
”
)的年份的读法应当将该
“
零
”
读为
O
〔
u
〕。
例如:
1809
年读作
eighteen O nine
4
)关于千年的一些读法。
2000
年读作
two thousand
2008
年读作
two thousand and eight
(或
twenty O eight
)
1008
年读作
one thousand and eight
(或
ten O eight
)
另外,还有一些非四位数的年份,它们有两种读法:
一种是按照基数词的方法来读,另
一种是一个一个数字来读。例如:
531BC
读作
five three one BC
(或
five hundred and thirty-one BC
)
附加知识:
2
.日期
日期是我们在日常生活中经常用到的数字之一。日期的写法 可以采用基数词和序数词两
种形式。例如:
March 1
也可以写成
March 1st
;
May 29
也可以写成
May 29th
。但是,日
期的读法只能用序数词的形式。例如:
October 31
(
October 31st
)读作
October
(
the
)
thirty- first
August 26
(
August 26th
)读作
August
(
the
)
twenty- sixth
3
.时间
时间的读法有以下一些特点:
1
)可以直接按照表示时间的数字来读。例如:
10
:
56
读作
ten fifty six
8
:
30
读作
eight thirty
2
)正点后的前半小时,通常说几点
“< br>过
”
(
past
)几分。例如:
9
:
25
读作
twenty-five past nine
2
:
16
读作
sixteen past two
3
)正点后的后半小时,通常说几点< br>“
差
”
(
to
)几分。此时,所说的
“
几点
”
指的是
“
正点
”
后的下一个
“
正点”
。例如:
10
:
55
读作
five to eleven
8
:
40
读作
twenty to nine
4
)英语中的
15
分钟也可以说 成
“
一刻钟
”
(
a quarter
)。例如:
4
:
15
读作
a quarter past four
