Our clothes sell so well in this country that we have no need to export.
- Our clothes sell so well in this country...
Is this part of the sentence a noun phrase although it has two words which are not nouns (so and well)? Can a noun phrase have adverbs and adjectives in it? Please explain.
- We have no need to export.
The second part of the sentence does not show any tense like present or past or future. Sometimes sentences have no situation, like present or past as in "all is well" or "everything is good". Does in such cases in sense of grammar we should use "be" verbs or sentence will be used as the present simple tense? What are the rules of grammar in such situations?
