“I” is used at the begining of a sentence (or proposition) and “me” will generally be at the end.

It should work 90% of the time, to get you going until you know how to use it properly.

I is used as the SUBJECT of a sentence. This does not depend on the word order, but on the function of “i” in the sentence, for example:

I am going to climb a mountain.

The hero was I.

Elly and I took a walk this morning.

(I is also never the object of a preposition, such as to or for or with)

Me is used as an object, either direct or indirect:

1. as a direct object:

He hit me.

Ask me a question.

Do you love Joe and me?

Indirect object (or object of a preposition):

Write me a letter!

He threw the ball to me.

Is that chocolate for me?

Second question:

There is no difference between hasn’t and has not. The first is just a contraction.

You’ve (or you have) gotten a lot of good answers up there.

Write them all down and carry it with you to use for a conversation. You will get use to saying it and hearing it – then you’ve (or you have) learned it.

Also, if you are going to be observant – listen to the music or songs that you know and sing it all the time. There’s a lot you can learn from the songs to – especially love songs and Christian’s songs.

If you are catholic and you like the song “I Believe” – that song has a lot of answers to your question.

Another song is “You and I”

The song by the Beatles: “Can’t Buy ME Love”

“I’LL buy (or I WILL) buy you diamond ring my friend, if you say you love ME too”

Contractions (shortened)

Have not (or haven’t)

I had not (or Ihadn’t)

I will (or I’ll) come back for more – this food fills me up.

I will not (or I won’t) say Americans are bad – they are very helpful to me.

I do not or (i don’t) recognize her – she gain wieght.

I would not (or I wouldn’t) exchange you for anything – I like you a lot. You like me too?

I am (or I’m) very interested – are you not?

He has not or He hasn’t ( He has not) or He hasn’t learned his lesson very well yet – he needs more time.

(Don’t) or Do not use I ain’t – this is illegal for educated people.

Good Luck.

He hates “me”

OR

“I” feel that everything is ok

Bring that to “me”

He has not and He hasn’t has the same meaning… however “hasn’t” is the shortened version of “has not”
