Before you start
Describe a task that is demanding but manageable.
See one possible response
It isn’t too difficult, but it needs care.
A fictional theatre group is checking a list of cues. The list matters greatly, the task is manageable, and nobody has yet confirmed that the checking is complete.
What you will practise
- Interpret a negated degree threshold without turning it into an absolute judgement.
- Distinguish evaluation of non-action from a barrier to action.
- Reformulate the construction without changing feasibility, evaluation or event status.
Respond before revealing. Preserve scope, attribution and evidence limits. A defensible alternative or genuine ambiguity must not be marked wrong merely for differing from the model.
Not outside too
Not too difficult to check denies that the difficulty exceeds a relevant threshold. It does not necessarily mean easy: the task may still need effort. The context supplies what counts as too difficult for this person or purpose.
The list isn’t too difficult to check, though it will take concentration.
The box isn’t too heavy for Sam to carry, but it is still heavy.

Not inside the infinitive
Too important not to check presents leaving something unchecked as unacceptable in the speaker’s evaluation. It encourages or argues for checking; it does not report that checking has occurred. Compare too difficult to check, which concerns a barrier to the action.
The cue list is too important not to check.
This question is too important to ignore.
Preserve scope and evidence
A good paraphrase keeps what is negated, whose threshold matters and whether an action is merely feasible, recommended or completed. Not too difficult, important enough to check and already checked answer different questions.
Checking is manageable, but we haven’t done it yet.
I regard checking as essential; that doesn’t mean the list has been checked.
Keep feasibility, evaluation and status separate

Guided practice
Say or write your answer first. Then compare the meaning and grammar with the model.
1. What is denied in The form isn’t too complicated to complete?
Compare a model and explanation
That its complexity exceeds the relevant threshold for completion.
It can still be complicated without being too complicated.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
2. Restate The figures are too important not to check.
Compare a model and explanation
The speaker considers checking the figures necessary because they matter so much.
This preserves the evaluation without claiming the action happened.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
3. Compare too difficult to revise with not too difficult to revise.
Compare a model and explanation
The first presents difficulty as a barrier in context; the second denies that it exceeds the relevant threshold.
Not changes the threshold judgement.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
4. Does The figures are too important not to check establish that they are correct?
Compare a model and explanation
No. It evaluates the need for checking, not their accuracy.
Importance is not evidence of correctness.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
5. Source: not too heavy for Sam. Summary: light for everyone. Repair it.
Compare a model and explanation
It is within Sam’s carrying capacity, though it may still be heavy.
The source does not generalise to every person or say light.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
6. Rewrite The issue is too important to ignore using a negative infinitive.
Compare a model and explanation
The issue is too important not to consider.
Consider is a useful contextual paraphrase of not ignoring, not a claim that every possible action is equivalent.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
7. Add a sentence showing that manageable does not mean completed: The task isn’t too difficult to finish.
Compare a model and explanation
However, we haven’t started it yet.
Feasibility and event status are independent.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
8. The group says checking is manageable and necessary, but still pending. Write two sentences preserving all three points.
Compare a model and explanation
The list isn’t too difficult to check, and it’s too important to leave unchecked. We haven’t checked it yet.
The final sentence prevents an unsupported completion inference.
Accept a grammatical alternative that satisfies the stated prompt and this item’s explanation; the model is not an exhaustive exact-string key.
A short conversation
Listen to the exchange, then take one role. The speaker labels identify roles; do not narrate them.
Open the conversation transcript
Stage manager: The cue list isn’t too difficult to check, is it?
Assistant: No, but it needs care. It’s too important not to check properly.
Stage manager: Then can I mark it as checked?
Assistant: Not yet. We’ve agreed it matters; we haven’t done it.
Listening checks
Listen to each extract, then choose the best answer. These three questions have their own score.
Answer key with explanations
Which conclusion is supported?
Its weight is within Sam’s stated capacity; movement is not confirmed.: The stimulus separates capacity from an actual move.
Compare all choices
- Its weight is within Sam’s stated capacity; movement is not confirmed.: The stimulus separates capacity from an actual move.
- Sam has already carried it.: The speaker says Sam has not been asked.
- It is light for everyone.: Neither lightness nor everyone’s capacity is stated.
What does the speaker express?
An evaluation supporting checking.: The speaker explicitly distinguishes the reason from completed action.
Compare all choices
- Confirmation that the list is correct.: Accuracy has not been established.
- An evaluation supporting checking.: The speaker explicitly distinguishes the reason from completed action.
- A claim that checking is impossible.: The message supports checking rather than ruling it out.
What would overstate the message?
Calling it effortless and already repaired.: Both ease and completion exceed the supplied facts.
Compare all choices
- Saying the repair has not started.: That is explicitly stated.
- Calling the repair manageable.: That preserves the threshold judgement.
- Calling it effortless and already repaired.: Both ease and completion exceed the supplied facts.
Mastery quiz
Choose the best answer for each situation. The score is out of eight.
Answer key with explanations
Which paraphrase best preserves isn’t too difficult to finish?
It is manageable, though it may still be difficult.: This denies an excessive threshold without erasing effort.
Compare all choices
- It cannot be finished under any circumstances.: That reverses the threshold judgement.
- It requires no effort.: That is stronger than the source.
- It is manageable, though it may still be difficult.: This denies an excessive threshold without erasing effort.
What does too important not to check primarily express in this lesson?
A judgement that leaving it unchecked is unacceptable.: The construction evaluates non-action.
Compare all choices
- A judgement that leaving it unchecked is unacceptable.: The construction evaluates non-action.
- A report that checking is complete.: Completion is not encoded.
- A claim that importance makes checking impossible.: The practical direction is the opposite.
Which pair differs in the relevant position of negation?
Not too difficult to do / too important not to do.: The first negates the threshold judgement; the second includes a negative infinitive.
Compare all choices
- Has done / had done.: This changes time marking, not the target construction.
- Not too difficult to do / too important not to do.: The first negates the threshold judgement; the second includes a negative infinitive.
- Difficult to do / easy to do.: This changes the adjective, not the position of not.
The source says not too heavy for Sam. Which inference is unsupported?
Everyone can carry it effortlessly.: The source concerns Sam and does not promise ease.
Compare all choices
- Sam’s capacity is the relevant comparison.: For Sam supplies that context.
- The box can still be heavy.: Not too heavy does not mean light.
- Everyone can carry it effortlessly.: The source concerns Sam and does not promise ease.
Which sentence clearly reports a completed action rather than feasibility or evaluation?
We checked the list yesterday.: Past simple here reports the action.
Compare all choices
- We checked the list yesterday.: Past simple here reports the action.
- The list is too important not to check.: This gives an evaluative reason to act.
- The list isn’t too difficult to check.: This evaluates feasibility.
A source says not too complicated, though demanding. Which edit is least faithful?
Completely simple and effortless.: It removes the explicit demand and adds stronger ease.
Compare all choices
- Manageable but demanding.: This preserves the contrast.
- Completely simple and effortless.: It removes the explicit demand and adds stronger ease.
- Within our ability, though it needs effort.: This is a reasonable contextual paraphrase.
What information helps interpret too in these patterns?
The relevant person, purpose and threshold.: Excessiveness is evaluated relative to context.
Compare all choices
- A universal numerical limit for every adjective.: No such universal limit applies.
- Whether the adjective is positive or negative in isolation, without any person or purpose.: The relevant threshold cannot always be recovered from adjective polarity alone.
- The relevant person, purpose and threshold.: Excessiveness is evaluated relative to context.
Which summary preserves the theatre case?
Checking is manageable and important, but not yet complete.: All three supplied facts remain separate.
Compare all choices
- Checking is manageable and important, but not yet complete.: All three supplied facts remain separate.
- Checking is finished because it is important.: Importance does not establish an event.
- Checking is unnecessary because it is manageable.: Manageability does not remove its importance.
Use it in your own words
A qualified ability judgement
Describe a manageable but demanding task without calling it easy. Identify whose ability matters.
Reveal a possible response
The instructions aren’t too difficult for our new member to follow, but they’ll need time and concentration. I wouldn’t describe them as effortless.
- Name the relevant threshold
- Retain possible difficulty
- Avoid a completion claim
Choose a harmless practical task.
A reason, not a result
Explain why something matters enough to check and clarify whether checking has occurred.
Reveal a possible response
The dates are too important not to verify. That’s my reason for checking them, not a claim that I’ve done it. At the moment, they’re still unverified.
- Use negative infinitive scope accurately
- Separate evaluation from status
- State the status explicitly
Different factual statuses are valid when stated clearly.
Put it all together
A fictional exhibition needs labels checked. The task is demanding but manageable; leaving errors would mislead visitors; work is not started. Give a precise spoken update using both target patterns.
Reveal a possible response
The labels aren’t too difficult to check, although we need concentration. They’re too important not to review carefully because visitors rely on them. We haven’t started yet, so I won’t describe them as verified.
- Preserve feasibility
- Preserve the reason to act
- Preserve the uncompleted status
Do not equate importance with accuracy or manageability with completion.
Take it with you
Not outside too denies an excessive threshold. Not inside the infinitive can change the practical evaluation. Feasibility and a reason to act are not proof of completion.
