英文高手請進(有關have同has幾問題)

首先人嘅眾數，例如you(你/你們)係+have，係唔受物嘅單/眾數影響
例a: I/you/we/they have an apple (have跟我I，而唔係apple)
例b:he/she/it has an apple

children係多過1個或０個，唔一定有好多．
例：no children`one child` ２children` 3 childen
does = has(單數) , do = have(眾數)

其實眾數只係1個概念，搞唔掂就當係公乸，靚女/醜女都得．好似我係1個人，但都用have．物嘅眾數都唔＝１，而唔一定好多．眾數可以+s/es，但係眾數係指人/物，唔包括動詞（have/do），只可以話個動詞跟單數/眾數名詞嚟分．

你應該咁諗I/you/we/they係高等嘅（因為有我/人多），所以用眾數：have, do，he/she/it係低等（因為人少，唔在場，唔係人:it），所以用單數：has, does

有not=否定句，同單數/眾數冇關，亦唔重要．
例：we do not have children（眾數否定句）=we have no children（眾數肯定句）
我地（眾數名詞）有（動詞,因為前面係眾數,所以用have）0個（數詞,好似1,2,3,4,唔分單數/眾數）仔女（眾數名詞）=眾數肯定句

- has係單數, 例子 :
John has a car. (John is a單數)
- have係眾數, 例子 :
Mary and John have a car. (Mary and John are 眾數)
Please raise your question here if you still are not clear about this question.

In general, we use has with a third person singular pronoun or noun, such as he, she, it, Peter, Mary and a table etc; and use have with all the other types of nouns or pronouns, i.e. I/you/they/we/dogs etc. However, you cannot over-generalise this rule. If has doesn't immediate follow a noun/pronoun, we use have instead of has even though the subject of the sentence is a third person singular pronoun or noun. I give you some examples

He has a pen.
He will have a pen.
He may have a pen.
She would like to have a pen.
He doesn't have a pen.
He can have a pen.

This explains the examples you quoted: he has a bath every day; he does not have a bath every day.

Again, adding s and es to a noun to make it become plural is also a general rule. There are exceptions and children is one example. Therefore, not all plural nouns end with s/es

Does is a verb, not a noun. We add s or es to a verb when the subject of the sentence is a third person singular noun or pronoun. The root form of does is do. So, when the subject of the sentence is a third person singular, e.g. he/she/it/Peter/Mary/ a table, we use does instead of do. The followings are some examples:

They do not like going out. (They is a plural pronoun)
He does not like going out. (He is a singular pronoun)
