Thanks FOR your help.
You're very welcome, Nanatuha.
I have understood the function of each word, but I still I have one question.[/COLOR]
"gone" is an adjective modifying "is".
"Gone" doesn't modify "is". It's a predicate adjective modifying "lunch". Adjectives modify nouns or pronouns.
"long" is an adverb modifying "gone".
Can I connect both with "and", even they are different about part of speech?
Can I ...........even though they are different PARTS OF SPEECH?
No, you can't.
