CPE Use of English Part 2 Open Cloze Tips and Tricks

Try our practice exercise at the bottom of this article.

What is CPE Use of English Part 2?

CPE Use of English Part 2 is the Open Cloze task in the C2 Proficiency Reading and Use of English paper.

You read a short text with eight gaps. For each gap, you must write one single word. There are no options to choose from, so you need to work out the answer from the grammar, meaning, register and structure of the text.

At CPE level, this task is not mainly about obscure vocabulary. The missing word is still often a small word: a preposition, pronoun, auxiliary verb, linker, quantifier or part of a fixed phrase. The challenge is that the surrounding language is more compressed, formal, idiomatic and conceptually demanding than at FCE or CAE.

What makes CPE Open Cloze different?

At C2 level, the answer may look simple, but the reason for the answer is often subtle.

The text may deal with abstract topics, argument, analysis, culture, science, society or academic-style discussion. Sentences may contain embedded clauses, nominalisation, contrastive structures and formal discourse markers.

CAE-style difficulty

advanced prepositions

formal linkers

complex relative clauses

common fixed phrases

abstract reference

C1-level idioms

CPE-style difficulty

highly condensed syntax

nuanced discourse links

less transparent fixed phrases

emphatic negative structures

precise quantifier choices

formal or literary register

This means CPE students need to read the sentence as a whole, not as a sequence of separate words.

Typical C2-level answer areas

CPE Open Cloze often tests the relationship between grammar, meaning and register.

Formal linkers and discourse

however

whereas

whereby

notwithstanding

nevertheless

insofar

albeit

lest

Reference and clause patterns

what

which

whose

whereby

whoever

whatever

whom

Fixed and semi-fixed phrases

to the extent that

on the grounds that

for fear that

in the event that

with respect to

Negative and emphatic patterns

neither

nor

hardly

scarcely

no sooner

under no circumstances

not until

little

You should not try to memorise every possible expression. It is more useful to notice how formal English builds relationships between ideas: concession, cause, contrast, condition, emphasis and reference.

Examples of CPE-level thinking

Look at this sentence:

The committee rejected the proposal, not because it lacked ambition, but ___ it failed to provide a realistic timetable.

Answer: because

The word itself is simple, but the structure is a balanced contrast: not because … but because.

Another example:

Rarely ___ a public inquiry produced such an immediate change in policy.

Answer: has

This tests inversion after a negative or limiting adverb: Rarely has …

Another example:

The author’s argument, ___ persuasive it may appear at first, rests on a questionable assumption.

Answer: however

Here, however + adjective/adverb introduces concession: however persuasive it may appear.

How to approach CPE Open Cloze

At C2 level, you need a slower and more analytical approach than at lower levels.

Before answering

Read the whole text.

Identify the argument or topic.

Notice the register.

Mark contrast, cause and concession.

For each gap

Read the full sentence.

Check both sides of the gap.

Identify the structure.

Test the answer grammatically.

Check spelling and register.

Do not rely only on what “sounds right”. At CPE level, several words may sound possible, but only one may fit the exact structure.

Common CPE Open Cloze mistakes

Mistake

choosing a common word where a formal linker is needed

missing inversion after negative adverbials

overlooking fixed prepositional phrases

ignoring the register of the text

treating the gap as vocabulary only

Better habit

study linkers by function

learn inversion triggers

record full expressions

read formal essays and articles

analyse the whole clause

For example, do not only learn extent. Learn the structure:

to the extent that
the extent to which

Do not only learn means. Learn:

by no means
by means of

This kind of phrase-level learning is essential for CPE.

CPE Use of English Part 2 Open Cloze Tips and Tricks; final advice for students

CPE Open Cloze tests precision. The missing word may be short, but the sentence around it may be highly sophisticated.

To improve, focus on:

Grammar precision

inversion

relative clauses

concession clauses

passive structures

modal perfect forms

comparison structures

C2 lexico-grammar

formal linkers

fixed expressions

dependent prepositions

discourse markers

negative structures

quantifier patterns

When you check your answers, do not simply write down the missing word. Write down the whole pattern.

For example:

however persuasive it may berarely has this happenedto the extent thatby no meanson the grounds thatthe extent to which

This is the most efficient way to prepare. CPE Open Cloze is not random. It tests whether you can see the hidden architecture of advanced English.
