✔ 最佳答案
Have - 複數用 (e.g. dogs, people, we, they, you) and I, you 用
Has - 單數用 (e.g. a dog, a person, he, she, it)
Have/has - Both can be verbs, 解作'有'
For example:
I have a dog. She has a cat.
They have a car. We have pasta for dinner.
Have/has + past participle (過去分詞) 則會構成 present perfect tence (現在完成式)
For example:
I have bought a book. She has finished her homework.
They have gone to movie.
