Look at two examples first:

1, 345,233 = one million, 345,233.

1, 684,234,465 = one billion, 684 million, 234,465.

Look carefully, do you find the pattern?

In English, one digit is represented by ten, two digits by one hundred, and three digits are represented by a new cardinal word, and then the new word is carried in the same way!

Ok, I'll tell you another practical rule. This time it's about the difference between "teen" and "ty". 15,50 sounds silly and unclear!

"-teen" and "-ty" are a pair of easily confused pronunciations. We can distinguish between sound and phoneme. The word with "-teen" has two stresses, that is, "-teen" should be stressed, and the vowel in "-teen" is a long vowel [ti: n], with long and clear pronunciation; The word with "-ty" has only one stress, that is, "-ty" is not stressed, and the vowel in "-ty" is a short vowel [[ti]], which is short and urgent.

Example:

Fifteen fifty.

Ninety nineteen.

In conversation, numbers are often key information, but I find that most people are confused about this information. The main reason is not that I can't hear it, but that I don't know the rules of reading English numbers at all. Through the communication with some people around me, it is found that quite a few students have not systematically studied the law of digital reading.

Therefore, to solve this problem, the most fundamental thing is to popularize the rules of English digital reading.

Of course, the pronunciation of numbers in Britain and America is slightly different. For example, in British English, the last two digits of a number (ten digits and one digit) must be "and", which is not used in American English, but it is harmless.

Let's begin to popularize the rules of digital reading.

Insert a sentence in the middle: please ask yourself, what is the correct expression of year, month and day?

Also, many times you can't understand the dialogue, not because the vocabulary used in it is complicated, nor because your vocabulary is not enough. When you hear a word, it is also very simple, such as apple (you have been exposed to this word since you started learning English), but you just can't react. No amount of words will help. The active words are the really meaningful part. A bird in the hand is worth than two in the bush. This expression may be problematic. In short, you have to find ways to improve your active words. More investment, there is still a long way to go.

First, let's start with the cardinal number.

First of all, master the pronunciation of numbers below three digits, because this is the basis of multi-digits. Once you master it skillfully, you can easily handle any huge number over four digits with the help of commas. We can illustrate this point through examples.

(1) Pronunciation of 3-5 digits

202 is pronounced: two hundred (and) two.

Pronunciation: 200 (and) 34.

1, 234 pronounced: 1200 (and) 34.

(2) Pay attention to the following points when reading:

A. In British English, the last two digits (ten digits and one digit) of a number must use' and', but not in American English. For example, 3077 reads: USA: 3,777.

B the indefinite article "a" is only used at the beginning of numbers with "forgotten" and "used". Try to compare:

146 pronounced: one hundred (and) forty-six.

2 146 pronunciation: two thousand, one forgot (and) forty-six.

C. 1 0,000, this integer, we said a thousand, and we also said a thousand before, but in a few hundred digits, we are going to say a thousand now. Try to compare:

1, 03 1 pronounced: one thousand, (and) one third,

1, 150 pronounced: one thousand, one thousand (and) five.

The singular of the words "D. Happy, thoughtful and millions" can be used with "A" and "one", but not alone. "A" is more common in informal style; When we speak more accurately, we try to compare it with "one":

I want to live for a hundred years.

The trip took a whole hundred days.

E. We often say "Happy Eleven" (1, 100), "Happy Twelve" (1 200) and so on, instead of thinking about one pleasure. From 1, 100 to 1, 900.

(3) How to read numbers with more than 5 digits.

1 1, the pronunciation of 234 is: eleven thousand two hundred (and) four thirds.

155,721pronounced: one happiness (and) 55,000, seven happiness (and) 21.

The pronunciation of 6,155,702 is: six hundred and one hundred and ten (and) five hundred and fifty-seven thousand and two minutes.

26,000,008 is pronounced as: 2,608.

326, 465, 438+04, 765, 438+08 is pronounced as: three loses (and) 26 million, four loses (and) 40 thousand, and seven loses (and) 800.

The pronunciation of 4,302,000,000 is: 4.3 billion hungry people (and) 2 million.

As can be seen from the above pictures, a multi-digit number has a comma for every three digits from right to left. This comma plays an important role and can help us a lot when remembering numbers!

Read the first comma backwards; Push three more places to the left, and the second comma is read as million; ; The third comma reads billion; ; The fourth comma is trillion. The function of these commas is that when we hear thousands, we immediately write down this number, followed by a comma, leaving 3 digits; When you hear a million digits, write it down and put a comma after it, leaving six digits; When you hear a billion numbers, the method is the same as above, leaving nine digits behind, and so on, so that all the numbers will be in their places.

For example, when you hear "twenty thousand four" and "write 20", and "four" means that there is only one person in the latter group, that is, 004, then the number written down completely is 20004; If you hear "six million and twenty to four hungry twenty-three", the first step is to write: 6,020, and then write the last group of 423 after the first comma. The complete number is 6,020,423. If you hear "one billion, four million hungry, twenty to four hungry twenty-three", the first step is to write 1, 104, the second step is to write the third group 020, and the third step is to write 423, then the complete number is 1 653. As long as we strengthen the three-digit reading and writing training in our usual training, we can distinguish "ty" from "teen" and make good use of this indispensable "comma". No matter how big the number is, it will not cause us obstacles.

Second, the reading method of ordinal number

Lst is pronounced: (the) first.

The second pronunciation is the second.

third

The fourth pronunciation is: (the) the fourth.

Twenty is pronunciation: (the) twenty.

2 1st is pronounced: (the) 21st.

The twenty-second pronunciation is: (the) the twenty-second pronunciation

Pronunciation on the 23rd: (the) 23rd and so on.

Third, reading fractions, decimals and percentages.

(1) score

The numerator in a fraction is expressed in radix and the denominator in ordinal number. Look at the numerator first, then at the denominator. When the numerator is greater than 1, add "s" to the denominator. take for example

1/2 pronounced: a/ half.

1/3 Pronunciation: one third

Pronunciation: one eighth

1/4 pronounced: a/ quarter (fourth)

Two-thirds pronunciation: two-thirds

1/5/9 is pronounced as one and five ninth.

More complicated scores are often represented by the word over. For example:

3 17/509 reads: three forgets seven, five forgets nine.

3/4 hour, 7/ 10 mile means 3/4 hour, 0.7 mile.

(2) Decimals

For numbers with decimal points, the decimal point "."is read as "point", and if there are more than two numbers after the decimal point, they are read separately.

0.5 Pronunciation: (zero) point five

0.25 Pronunciation: (zero) point two five

0. 125 reads: (zero) point one two five.

93.64 meters pronunciation: 93.64 meters.

2' 15. 1 1' Pronunciation: two minutes and five point one seconds.

(3) Percentage

Just add "percent" after the corresponding number to read the percentage. For example:

25% is read as 25%.

1 1.3% read eleven point three percent.

Fourth, reading the year and date.

Years expressed by numbers are usually divided into two halves.

2000b. Pronunciation: 2000 BC

1558 pronunciation: fifteen fifty-eight.

1603 is pronounced six teenagers (hungry and) three/603.

92 1 Pronunciation: 921.

British and American expressions of dates are different, please pay attention to the differences.

When writing a date, the British write the date first and the Americans write the month first.

English19991April 6, 999 = April 6.

USA1April 6, 999 = April 6 1999

In reading, the British have two expressions:

1. April 6th, 1999

2. April 6, 1999

Americans generally say this:

April 6, 1999 (omit "the")

Five, the reading method on the hour

We should pay attention to the current British and American pronunciations.

hero

7: 00 a.m./7: 00 p.m.

A quarter past eight/a quarter past eight

Half past nine/half past nine

Quarter to ten, nine forty-five.

10:03 past three o'clock

The usage in the United States is basically similar, except that the past tense is used in Britain, and the United States usually uses after；; To is used in Britain and fo is commonly used in America. American 5: 15a 5: 15.

Half past nine/half past nine

9: 45/9: 45

Nine fifty-five, ten fifty/nine fifty-five.

When used in military orders and travel plans, the pronunciation is as follows:

07:00 (Oh) 700 hours = 7 am

9 am 15 pm

12:00 1200 hours = noon/noon

13:45 13: 45 = 65438+ 0:45 pm

19:00 19:00 = 7:00 p.m.

23:05 Twenty-three (oh) five = 165438+ 0:05 pm

24:00 Twenty-four hours = midnight

24: 10 twenty-four ten = ten after midnight.

Telephone number, temperature and house number reading.

(1) phone number

When reading telephone numbers, each number is read one by one, and "o" is pronounced as d1[ou] in English; Americans read zero (sometimes zero). When the British read two identical numbers, they usually read them as doublex, especially when the two numbers are in the same group (the telephone number is a group of two numbers from right to left). For example:

The pronunciation of 345-6638 is: 345, double 638.

307-4922 is pronounced: 307, 49 pairs of two, while in the United States it is pronounced: 307, 4922, but if the same two numbers are not in the same group, they can have two pronunciations. For example, 62899033 can be pronounced as six two eight double nine oh double three or six two eight nine oh double three, but 99033 can never be pronounced as nine nine oh three three. On the contrary, when the numbers are the same, American will repeat the numbers. But there is an exception in Britain. The emergency telephone number 999 is always pronounced as nine, nine, nine.

(2) Temperature

There are two kinds of temperatures: Fahrenheit and Celsius. Both Britain and the United States use Fahrenheit as the unit for measuring temperature. The usage of degrees Celsius is becoming more and more common.

15℃ Pronunciation: Five Centuries (or Celsius)

32 degrees Fahrenheit: 32 degrees Fahrenheit

Pronunciation: zero degrees Celsius

-5C Pronunciation: five degrees below zero

(3) the house number.

When the house number meets three digits, read each digit separately, and when it meets four digits, read half. For example:

The pronunciation of room 302 is: room 302.

349 1 King Street Pronunciation: No.3-No.491 King Street.

..... Congratulations on seeing this. Let's take a look at meko's two tips, which lazy people can't see (May 9) ...

In daily spoken English, Americans usually casually say a long list of numbers. Sometimes even a hundred &; Don't say anything about it. 543 will say five forty-three, 1234 will become twenty-three fours.

Speaking of telephone numbers, they are more accustomed to saying three numbers. Because the first three digits are the area code of the United States.

I know, you can not only read English numbers, but also write! ! !

This part mainly talks about: which occasions are represented by words and which occasions are represented by Arabic numerals. English-speaking countries have formed several established rules when writing numbers.

First, publishing houses in Britain and America follow a principle when typesetting, that is, 1 to 10 is expressed in words, and numbers above 10 are expressed in Arabic numerals (some are bounded by 100).

That table is 10 feet long and 5 feet wide.

The working head is 10 feet long and 5 feet wide.

The traditional mode of college classroom teaching is that professors and 20 to 30 students spend 45 to 50 minutes two or three times a week.

The traditional teaching method in university classroom is that a professor and twenty or thirty students meet two or three times a week for 45 to 50 minutes each time.

2. It is more concise to use Arabic numerals to represent the number of people, but it is more appropriate to use words to represent indefinite numbers and approximate values.

There are 2038 17 voters on the electoral roll.

There are 2038 17 voters on the electoral list.

Nearly thirty thousand voters took part in the election.

Nearly 30,000 voters participated in the election.

3. Encounter dates, percentages and special numbers with units, usually Arabic numbers.

The maximum rotation angle of the workbench is120.

The maximum rotation angle of the workbench is 120 degrees.

For example, March 3rd l99 1 or March 3rd L991;

5% discount (5% discount);

Bought 7 yards of carpet (bought 7 yards of carpet);

Ordered 2 pounds of minced steak (2 pounds of minced meat)

If the number and units involved are uncertain, they can be expressed in words.

About five miles per hour (about five miles per hour)

At least ten yards away (at least 10 yards away)

Hesitate for a moment (hesitate for a moment)

How many times have I warned you? )

Numbers appear frequently in scientific and technological articles, and it is more advantageous to express them in Arabic numerals than in words.

The new engine has a volume of 4.3 liters, a rotation speed of 4,400 revolutions per minute and an output power of 153 kW.

The volume of this new engine is 4.3 liters, the speed is 4400 revolutions per minute, and the output power per hour is 153 kw.

We know that the weight of a cubic foot of air is 0? C and 76cm, and the pressure is 0.08l pound, or 12 cubic feet of air weight 1 pound.

As we know, the weight of 1 cubic foot air is 0.8 1 pound at 0 degrees Celsius and 760 mm Hg pressure, which means that the weight of 12 cubic foot air is 1 pound.

5. Don't use Arabic numerals at the beginning of the sentence, and try to avoid using Arabic numerals at the end of the sentence.

July 4th is an important day in American history.

It should be written as July 4.
