C2 Proficiency open cloze practice with answers

C2Reading & Use of English40 questionsUpdated

The C2 Proficiency open cloze gives you no options at all: you supply one word per gap, and almost every answer is a function word. Articles, auxiliaries, prepositions and the second half of a fixed phrase do most of the work, so the task rewards grammar and discourse awareness more than vocabulary breadth.

What this task tests

  • Grammatical structures signalled by a single word: inversion, comparison, unreal conditionals.
  • The missing half of a two-part fixed expression such as by and large or not so much X as Y.
  • Linkers and discourse markers that show concession, contrast or consequence.
  • Reference: which pronoun or determiner points back to what earlier in the text.
  • Dependent prepositions in nominal phrases, where the noun rather than the verb decides the choice.
  • Auxiliary and modal use, including the perfect infinitive after modals of deduction.
  • Quantifiers and determiners in fixed frames: little, few, much, whatever, whichever.
  • Relative and nominal clause markers, including the difference between which, whose and whereby.
  • Ellipsis and substitution with do, so and one, where the missing word replaces a whole phrase.
  • Spelling accuracy in the function words candidates most often mangle: whereas, albeit, nonetheless.

How to do it

  1. Step 1:

    Read for the argument before you write anything

    Open cloze gaps are decided by the direction of the text. If the sentence reverses what came before, your gap is probably a concessive word; if it extends it, an additive one. Know the direction first.

  2. Step 2:

    Name the word class

    Before choosing a word, decide whether the gap needs an auxiliary, a preposition, a pronoun, a determiner or a linker. That single decision removes most wrong answers and stops you writing a content word by reflex.

  3. Step 3:

    Look left for triggers

    No sooner, hardly, little, under no circumstances and such all trigger inversion, which means the gap after them is very often an auxiliary. Train yourself to see the trigger and write did, had or was without hesitating.

  4. Step 4:

    Say the phrase aloud in your head

    For fixed expressions the ear is faster than analysis. By ___ large, in the ___ run, on the ___ hand: if you have read enough, the missing word arrives before the reasoning does.

  5. Step 5:

    Trace every pronoun to its referent

    Where the gap is a pronoun or determiner, find the noun it stands for and check number and animacy. A gap that looks like it wants it very often wants those, so or one.

  6. Step 6:

    Watch for two-part structures split across a line

    Not only ... but also, so ... that, such ... that, the more ... the more. If you can see one half above the gap, the gap is the other half, and no amount of meaning reasoning is needed.

  7. Step 7:

    Check that your word fits the whole sentence

    The commonest lost mark is a word that fits the five words around it but breaks the sentence. Reread each completed sentence in full before moving on, and check that no contraction is needed.

  8. Step 8:

    Fill the easy gaps first, then reread the text whole

    Most candidates solve six gaps quickly and stall on two. Complete the text with the six in place and read it straight through: the remaining gaps are usually obvious once the argument is continuous.

Mistakes that cost marks

  • Not thisNo sooner she had arrived than the phone rang.

    ThisNo sooner had she arrived than the phone rang.

    No sooner in front position forces subject-auxiliary inversion. Candidates write the auxiliary in the gap but leave the word order unchanged.

  • Not thisDespite of the delay, the launch went ahead.

    ThisDespite the delay, the launch went ahead.

    Despite takes no preposition; in spite of does. The two structures collapse into one another under time pressure.

  • Not thisThe plan was expensive, although effective.

    ThisThe plan was expensive, if effective.

    Where the gap is a single concessive word before an adjective, if is the idiomatic choice in formal prose. Although wants a clause to feel natural here.

  • Not thisSuch was her insistence, the matter was reopened.

    ThisSuch was her insistence that the matter was reopened.

    Such was X that Y is a two-part structure. Dropping that leaves a comma splice and loses the mark even though the inversion is right.

  • Not thisNo sooner had he sat down when the bell rang.

    ThisNo sooner had he sat down than the bell rang.

    No sooner pairs with than; hardly and scarcely pair with when. The two patterns are learned together and then confused.

  • Not thisThe report, whose conclusions were ignored, was published in March.

    ThisThe report, whose conclusions were ignored, was published in March. (correct) — but not: The report, which conclusions were ignored, ...

    Possession inside a relative clause needs whose, even with an inanimate head noun. Which conclusions is the error candidates actually write.

  • Not thisHe must had known about the delay.

    ThisHe must have known about the delay.

    Modals of deduction take have plus a participle. The gap wants have, and had is the reflex error under time pressure.

1Complete the sentence.

No soonerthe ink dried than the policy was revised again.
___ as it may seem, the older method proved the more accurate of the two.

3Complete the sentence.

Were it notthe strike, the project would have finished in March.
Decide whether each statement about the open cloze is true.
  • Most answers are grammatical words rather than content words.
  • Contracted forms such as don’t are normally accepted as one word.
  • A gap after 'hardly' at the start of a sentence is likely to need an auxiliary verb.

Decide whether each statement about inversion is true.
  • Under no circumstances should the door be propped open is correctly inverted.

Frequently asked questions

Can I write two words in one gap?

No. One word per gap, and a contraction counts as two, so write do not rather than don’t if the structure allows it and rethink the gap if it does not.

Does spelling matter in the open cloze?

Yes. A misspelled function word is marked wrong even when the grammar is right, and words like whereas, albeit and nevertheless are exactly the ones candidates mangle.

Are American spellings accepted?

Consistent American spelling is generally acceptable in Cambridge exams, but mixing conventions within one paper looks careless. Choose British spelling and stay with it.

What if I can think of two words that both fit?

Write the more common one. Where two answers genuinely work, both are normally on the mark scheme, but an unusual word that only just fits is a risk with no upside.

How do I practise this task on my own?

Take any well-written article, delete every eighth word by hand, leave it a day, then fill it in. Deleting mechanically rather than choosing gaps forces you to deal with the function words this task actually tests.
