Question

a woodcutter felled a tree change into past continuous​

Answer 1

The ‘simple possibilities’ have been examined by Joseph Siegal, who rightly concludes that - to state the opposite, which could be construed as ‘negative’ - whereas the syntax holds up, the very notion seems absurd. I could put it differently - ‘Woodcutters REFRAIN FROM TREE-FELLING’ - but this would remain a positive statement.
