be going to vs. present continous for future arrangements & will + must/musn’t
be going to, has two different function. first, to talk about things that we intend to do in the future. ex :
i’m going to become an artist in 10 years’time.
second, to make predictions based on things we know or can see.
Look at the clouds. It’s going to rain soon.
how about the negative and interrogative sentences of be going to? ok. the pattern is :
(-) S + be + not + going to + v1/be+adj + C
(?) be + S + going to + V1/be+adj + C ?
be going to vs. present continous for future arrangements.
be going to means something that we intend to do / predict – will happen in the future. but, if present continous. it means something that we arranged/planned to do in the future, it’s kind of fixed arranged. ex :
i’m going to talk about this problem tomorrow. (we intend to talk about the problem) , but if
i’m talking about this problem tomorrow. (stronger, we 100% going to talk about the problem, not just an intend but a fixed plan!)
be going to vs. will
be going to, is for something that means…in longer time. will is for the shorter one. “???”!
ok. i bet u don’t understand. then, look at the example:
i’m going to wash it!
i’ll wash it! (it means something that firm, and in a hurry/shorter time than the going to sentence)
or it can means “response of something”. ex :
*your friend can’t solve the homework*, and then you say “i’ll do it!” but if going to, it means you intend to do it, not a response of something but an intend.
must is similliar to have to. but they’re DIFFERENT! what is the different between them?
must is for something that 100% u need to do. but have to is for something that less than 100% u need to do/its possible for you to “not do it”. so, must is for something that necessary/very important to do. and have to is for something that not necessary to do, although you can if you want to. ex :
I have to go (it isn’t very necessary to do, its ok if you don’t go)
i must go (it’s necessary for you to go! firm-)
OK. Now, how about must/musn’t pattern??
the pattern is same as will/won’t pattern. u don’t have to wear to be, because must/musn’t is a modal too. ex:
i must eat this before class time.
