Re-write the following sentences according to the instructions given after each. Make other changes that may be necessary, but do not change the meaning of each sentence.
I have never seen a film as bad as this. (Begin: This is ..................)
Topic: Degrees of comparison — positive to superlative
Answer
This is the worst film I have ever seen.
Converting a negative POSITIVE-degree comparison into a SUPERLATIVE.
Positive: I have NEVER seen a film AS BAD AS this. Superlative: This is the WORST film I have EVER seen.
Two changes: "never" becomes "ever", and "as bad as" becomes "the worst". Note that the negative disappears entirely, because the superlative already carries the meaning.
WATCH THE IRREGULAR FORM. The superlative of BAD is WORST, not "baddest" and not "most bad". The irregular comparisons to learn as a set: good — better — best bad — worse — worst little — less — least much/many — more — most
The 2018 paper sets the same conversion with "ill-fitting", where the regular "most" form is correct — so check whether the adjective is regular before you write.
