HAVE e HAVE GOT
HAVE e HAVE GOT  são maneiras diferentes de se dizer que se tem algo, mas possuem algumas diferenças que serão vistas no final:
    I have two kids and a dog --> I've got two kids and a dog

I've got = I have got

    You have a nice car --> You've got a nice car
    He has a really big apartment --> He has got a really big apartment

He's got = He has got

    I don't have any kids (maneira mais comum) --> I haven't got any kids

O "have got" é mais utilizado em frases afirmativas apenas, com negativas e interrogativas utiliza-se mais apenas o "have".

    Does it have problems? -- Yes, it's got a ton of problems / No, it doesn't have any problems

Perguntas:
    Have I got?
    Have you got?
    Has she got?
    Has he got?

Negativas:
    I haven't got
    You haven't got
    He/she/it hasn't got
    We haven't got
    They haven't got

A diferença entre um e outro:

"The present tense form of have with got used for possession is more than twice as frequent in spolen British English as in American English."

"You use 'have got' to say that someone has a particular thing, or to mention a quality or characteristic that someone or something has. In informal American English, people sometimes just use 'got'."

    I got a car
    I got a T-shirt just like that
    You got any identification?
    We got an extra one here
    They got a lovely daughter

"You use 'have got to' when you are saying that something is necessary or must happen in the way stated. In informal American English, the 'have' is sometimes omitted."

Have got to = gotta
    I gotta go!
    You gotta see this!
    You gotta be joking
    She gotta call us first
    They gotta read the report
    What you got there?
    I gotta a huge family
    You got anything to tell me?
    He got things to do
    They got a wonderful
    I gotta stay here
    She gotta show me what she's capable of

CAUSATIVE HAVE

Clique aqui para ver o post sobre voz ativa e voz passiva em inglês.

Quando algo é feito por ou para você, utiliza-se o CAUSATIVE HAVE, que é a voz passiva, basicamente:
    I had my hair cut (Ao invés de "Eu cortei meu cabelo")
    I will have my apartament painted
    I get my car fixed

É diferente do português, onde se costuma dizer "cortei meu cabelo", "arrumei meu carro", como se a pessoa tivesse cortado o próprio cabelo ou arrumado o próprio carro.

Estrutura: Sujeito + have ou get + objeto + verbo (past participle)
