2. None of THESE things ...
co do none, to róznie to z nim bywa, znalazłam coś na ten temat :
None is always singular.
Not always. In fact, none is more likely to be plural.
Many people seem to have been taught (mistakenly) that none always means "not one" (as in, None of the chickens is hatched). But most authorities have always believed that none is closer in meaning to "not any (of them)" than to "not one (of them)." So it's considered plural in most cases and takes a plural verb: None of the chickens are hatched.
None is singular only when it means "none of it"—that is to say, "no amount." (None of the milk was spilled.)
If you really do mean "not one," say "not one."
