English Grammar sentence help!?

[Tsering Lama]

Hi.. My name is Tsering and I have been learning grammar for many days. I am having many problems with it and two specific problems are word/phrase/clause order in a sentence, and saying 1 sentence in 2 different ways and being grammatically correct at the same time.

Ex: Arguments for the SMS are typically invoked in settings involving considerable uncertainty and potentially irreversible loses.

Why can't you say: Arguments are for the SMS typically invoked in settings involving considerable uncertainty and potentially irreversible loses.

or
Typically invoked are arguments for the SMS in settings involving considerable uncertainty and potentially irreversible loses.

I know the sentences sound weird but can you guys tell why Why in a strictly grammatical sense.

Ex: He could not help but see that.

He could not help seeing that.

How can you say these sentences in two ways yet they are both grammatically correct.

Last Ex: I desperately want to gain flexibility.
- I desperately want to be flexible.

Both "gain and be" are verbs so why is "gain"followed by noun "flexibility" and "be" by adjective flexible.
-Can you also say "flexibility is what I want to gain desperately."

Question about saying sentence in millions of different ways always confuses me like how can they be all grammatically correct. When can you write a sentence and when can you not.

Thanksss so much...

Hi,
I think for your first example, we must consider the first phrase as a subject:

Hi Lama. I think your question must be left to your english teacher. I mean the teacher from your country and who speaks your language. After hearing you said that you'd learnt english grammar for SOME DAYS, I know that you're now a beginner. There are many new terms in english must be explained to you in your language by your teacher himself. I mean the equivalent terms. When I started to learn english, my teacher did so. They're basic rules from which I can build my english knowledge myself better. Sometimes, there are something native teachers can't teach you better than your teachers. That's why we always learn philology before other subjects and mother tongue before other languages.

I don't think Lama is that much of a beginner, BS. He'd never have been able to construct that post if he hadn't been learning for more than 'some days'. I think that was just an incorrect choice of phrase.

Of course everyone wants to learn a language with native speakers but what will happen if we know nothing about it? When learning a new language or whatsoever, we need a basis. This basis helps us know how the language works and from which we will have targets to reach. Notice that every foreign language center has native speakers on behalf of tutors.

BS,
I really don't like to call you an idiot. Anyway, watch you words, kid! You don't have the right to scold me!

If I didn't have some friends form Vietnam, I would think Boy! Every Vietnamese is a bad mouth one!
