How would you know which is which?
Is the way to parse a phrasal verb is to see if the verb can separated from its particle by an adverb or not?
1) "They were shone on by the everlasting Sun". Here "shine" and "on" cannot be separated by an adverb so it is considered as an adverbial phrasal verb because “on” is an adverb?
2) but if we put an adverb into "shine on" like "The sun shone brightly on us" "shine on" is not an adverbial phrasal verb anymore because “on” here is a preposition?
Hope it's clear...
