just same but, i have is in present and i have got is in perfect tense. and also, we can't shortened I have in present but we can shortened I have got in perfect. I mean for example : - I've 3 cats = this is wrong.. you just must be write = I have 3 cats - I've got 3 cats = this true, because we can shortened have into the subject.

first we have to tell them about the usage of simple present.. so the usage is 1. daily activity, e.g : I go to school everyday 2. habitual, e.g : I always get up at 6 AM 3. fact, e.g : the earth is round. actually all of them interrelated.. after that. you have to tell them about "SUBJECT" in pronoun. then we can continue to tell them if in tenses itself has 2 different type. I mean "THE NOMINAL" and "THE VERBAL". first. we tell them about nominal sentence. 1. tell them what the usage of nominal 2. tell them about TOBE 3. give them the formula 4. give the example. note : if they ask about "What the function of tobe?" so, of course we have to tell them it all, like what the usage and give the example. second, then tell them about the verbal. 1. the usage 2. the formula 3. and remind them about the usage of "S/ES" in the end of the verb and the usage of "DO/DOES" so they can understand what the different.. so in the end.. we have to tell the conclusions about the different between "NOMINAL SENTENCE" and "VERBAL SENTENCE" in PRESENT. and don't forget to tell the time signal in present. so, that's my experience when i teached my students...

well, they called MODAL in English and part of "Helping Verb" that can stand by itself. so actually can, will, shall are use in present. and could, would and should is use in past and they're more polite than can, will, shall. well, the sixth usage of the words almost have same meaning, but it doesn't mean we can use that words freely, it must be adapted to our speaker and conditions of that time..

It was interesting and sometimes confusing.. but I do really like when I can understand what the sentence means and what I should change of them. It just like a riddle, i think.. umm, i think tenses is easier..
