In English papers or other official documents, numbers are usually read directly instead of the serial number "-"attached to figures and tables. For example:

The number 1 is pronounced as the number one.

Figure 2 is read as Figure two.

The number 1-3 is pronounced as the number one three.

Table 4 is pronounced Table four.

Table 4-2 is read as Table 42.

"-"is a hyphen, don't read it. Read the following numbers directly.

Therefore, figure 1-3 in the above example is read as drawing one three, and table 4-2-2 is read as table four two.

Besides charts and tables, other types such as charts (graphs), diagrams (patterns) and illustrations (illustrations) also have the same numbering rules. Read the following numbers directly, not "-".

Sometimes, files will have alphabetical numbers, as shown in Figure A- 1 and Figure A-3. The pronunciation is the same, pronounced directly as Figure A 1 and Figure A 3.

In addition to the serial numbers after figures and tables, similar serial numbers will also appear in the text, such as:

For example 1 read example 1.

Step 2: Read Step 2

The third stage is read as the third stage.

Wait, the rules are the same, just read numbers instead of "-".

In short, in formal English literature, the numbers with "-"after the serial number are usually not read, but directly behind the numbers. This is a relatively common specification.

If you are not sure or confused about the pronunciation of "-"in the serial number, please continue to ask. I would be happy to provide further explanations and examples. Your understanding of these norms is an important step to improve your English ability, and I am willing to take the time to help you improve this knowledge.

Good luck with your English study!
