Q. it was a present perfect, am I right? And since they wrote have, it means it's plural, isn't it?
A. WHEN TO USE Have Had & Had Had
In the present perfect, the auxiliary verb is always have (for I, you, we, they) or has (for he, she, it).
In the past perfect, the auxiliary verb is always had.
So yes it is present perfect and plural, however it is the "kids" that defines the plural not the "have" in this instance. Have can also be used with the singular "I" and "you".
Ref Have & Had In English
So, is it also correct to say:
People like him are talented;
Adults like my father are so lame;
Children like my son like to play;
A. Once again; It is not all about grammar To answer this question first you need to define the sentence. Does what you have written make sense, even when you are just using them as examples?
Talented in what? or should it be Talented People like him?
Are all adults lame? Do all children like to play?
Talented People like him; Children like to play; Some adults, like my Father are lame.
It would be different if you were to add more detail
*Artists like him are talented;
Jerks like my father are so lame;
Then I tried to translate a sentence (my original language to English), this is the sentence:
Singular ?
People like me are someone who never gives up. This is incorrect
The correct translation would be
A person like me is someone who never gives up.
Plural
People like me are people who never give up.
so look at what you have written "people (like me) are people", "who never give up" Well I think we already know people are people so we only need to write people once and to define who they are a third time is also unnecessary so we can drop the "who" and simplify the sentence to .
"people, like me, never give up"
Kids (like Bryce) have….
