Reading some mathematical symbols and words in English
1 and year

There are several ways to read a four-digit year:

1) Generally, the four numbers representing the year are divided into two groups, and the numbers in each group are read according to the cardinal number. For example:

1865 pronounced eighteen sixty-five.

2) If the first two digits are non-zero numbers and the last two digits are zero respectively, the first two digits are read first, and the last two digits are read as hundreds. For example:

1900 is pronounced as 1900.

3) The year with the third digit of "zero" (other digits are not "zero") should be read as o [u]. For example, 1809 is pronounced as 1809.

4) Some books about the Millennium.

In 2000, it was declared two thousand years.

2. Date

Reading and writing English dates are different from Chinese, so we should pay attention to this difference.

The English expression of middle age, month and day is "month+ordinal number, year". April 2, 200 1 year should be written as April 2, 200 1 year, and read as April 2, every two days.

Ordinal numbers are usually followed by -th, but in some special cases, they are recorded according to the following rules: 1, 2, 3 respectively (i.e. first, second and third), after 8, there is less T, 9 is less E (i.e. eighth and ninth), and 5, 12 changes ve to fth. For example:

October31(October31st) is pronounced octopus (the) as the third and the first.

3. Time

Time reading has the following characteristics:

1) can be read directly according to the number representing time. For example:

10: 56 is pronounced as 10: 56.

2) Half an hour after the punctuality, what time is usually said to be "past". For example:

9: 25, 9: 25

3) In the second half hour after punctuality, it is usually said that what time is "arrived". "What time" at this time refers to the next "punctuality" after "punctuality". For example:

Pronunciation is five minutes to eleven.

4) 15 minutes can also be called "quarter" in English. For example:

4: 15 is pronounced as a quarter past four.

7: 45 is pronounced a quarter to eight.

4. Scores and percentages

A. 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. For example:

1/2 pronounced: a/ half.

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

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

3/4 hours, say three quarters of an hour (three quarters of an hour); 7/ 10 mile means seven tenths.

Miles (seven tenths of a mile).

B, percentage

Just add "percent" after the corresponding number to read the percentage. For example, 25% is read as 25%.

5. 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)
