The following sentence is copied from the Cambridge Dictionary.
Our goods sell so well in this country that we have no need to export.
There are two questions of this sentence.
The first part of this sentence has noun phrase but it has one words which is not noun or adjective. Is it allowable to use adjective and adverb in the noun phrase.
The second part of this sentence that we have no need to export looks to me a present simple tense but the rule says that it should be written as we do not have need to export. Needs some comments on it.
