***** NOT A TEACHER *****
Hello, Dido:
I have found some information that I wish to share with you.
A world-famous grammarian makes these points:
1. You cannot say, "This house sold yesterday" if you are referring to "a single act of selling."'
2. You may, however, say, "His books sell very well."
a. "We think to some extent of the books as active themselves, rather than the activity of the bookseller."
b. "We indicate in such a sentence something that is felt as characteristic of the subject." [my emphasis]
i. "Therefore the verb generally requires some further descriptive term."
[Only my note: He seems be saying that "Some of the fruit here sells" needs "well" to make the sentence acceptable.]
3. Here are two more of his examples: "The meat cuts tender" and "His scientific papers read like novels." [my emphases]

A book that is very popular with students and teachers says this:
4. In some sentences, "the intransitive use has a meaning rather like a passive." [my emphasis]
a. Transitive: "We are selling a lot of copies of your book."
b. Intransitive: "Your book is selling well."
