Help me distinguish between the following English prepositions

I think that to distinguish the usage of some prepositions, it is better to find the corresponding scene, so that the understanding will come quickly!

There are too many meanings, and the meaning will change depending on the context.

I suggest you go and buy a book dedicated to prepositions.

1.shield a from b is a fixed pairing, which means "to protect a from b". For example:

he shield his eyes from the sun.He covers his eyes from the sun. The first part of the original sentence should be the third-party payers shield us from the cost of our care, which means "third-party payment makes us no longer worry about the safety of our funds."

Literally translated as "third-party payments protect us from spending energy"). Since the first part of the original sentence is a participle phrase, the translation can be Chinese "Since the third-party payment ensures the safety of our funds,...”

2.Here the possibly modification can be done, and can possibly be done means "all that can be done". possibly is usually fixed in a position similar to this usage:

It is always placed after the conjunctive verb; When a predicate verb contains an auxiliary verb, a modal verb, it is always after the first auxiliary verb (e.g., the position of the original sentence possibly).
