Under what circumstances should English words be added ES / Ed / ing

There are two cases of es: 1. Plural nouns ending with s, SH, CH, X and adding - ES / iz / bus buses / watch watches ending with O and adding es, such as: potato -- potato, tomato -- tomato
2. In the third person, the verb ending with "s, x, CH, SH" is pronounced as "iz" by adding "es" at the end of the word
teach－teaches [iz]; watch－watches [iz]
For verbs ending in "O", add "es" and read [Z]
go－goes [z] do－does [z]
3. ED is a regular change of the verb past tense, such as watch watched
4. The ing form is used for continuous tense

The general representative of an ER or is a person of a certain occupation
"Ing" is a present participle. In short, it is used in the present continuous tense

Use the past participle when you come across the past tense

Why add es after English words?
We have learned the third person singular form, such as goes and so on. We have added es. The teacher asked us to find out why we need to add es.

If it is after a noun, it is the plural of the noun, which means more than one thing the noun stands for. If it is added after the auxiliary verb do, it is the third person singular as the subject

Primary school teachers say "add es" and middle school teachers say "add s"

If there is life, add es, otherwise add s
For example: tomato → tomatoes potato → heroes hero → Heroes
↑
All three words are alive
Another example: photo → photos Park Zoo → zoos
↑
Both words are inanimate
