What B1 Reading Part 6 looks like: format, function words, an official sample solved gap by gap and a step-by-step strategy.

We’ve reached the final stop of the Reading paper: B1 Preliminary Reading Part 6. It’s the only one of the six parts where Cambridge doesn’t give you any options to choose from. You get a short text with six gaps, and for each one you have to come up with the missing word yourself. One word, no hints, no A, B, C or D.
In this guide I’ll explain what B1 Reading Part 6 looks like, what kind of words Cambridge is actually after here (and what kind it isn’t), and we’ll solve an official sample together about a trip to the Natural History Museum. 🙂
The Reading paper of the B1 Preliminary has six parts, 32 questions and 45 minutes, and it’s worth 25% of the final score. This is the last one:
| Fact | B1 Reading Part 6 |
|---|---|
| What you have to do | Read a short text with 6 gaps and write the missing word yourself in each one |
| Number of questions | 6 (numbered 27 to 32) |
| Options | None: no alternatives are given, you have to produce the word |
| Scoring | 1 point per correct answer |
| Recommended time | Between 6 and 8 minutes |
| What it tests | Grammar knowledge: prepositions, discourse markers, articles, possessives and other function words |
Like Part 4, this task was introduced with the 2020 reform and didn’t exist in the previous exam. It’s the little sibling of B2 First’s Use of English Part 2: if you already know that task, you’ll find the same mechanics here, at a simpler level.
This is the key difference from Part 5: there, you chose between four content words (nouns, verbs, adjectives) competing on meaning. Here, the missing words are almost always function words — the ones that hold the sentence’s structure together rather than carry its meaning. Specifically, you’ll usually get gaps like these:
You’re almost never asked for a noun, a content verb or an adjective — the text already gives you those. What’s being tested is whether you know which small grammatical piece is missing for the sentence to work.
Let’s work through an official Cambridge sample task: a text about a visit to the Natural History Museum.

Try filling in the gaps yourself before reading on.
«I’ve learned a huge amount about animals and plants (27)……… time I’ve visited.»
every / each, correct. Every time or each time means «on each occasion», and it’s the only way to say she learns something different on every visit.
«There are hundreds of interesting things on display, but (28)……… you like dinosaurs the best time…»
if, correct. It’s the conjunction that introduces the condition: «but if you like dinosaurs…».
«…the best time (29)……… see them is during term-time.»
to, correct. After the best time you need an infinitive with to: «the best time to see them».
«…the queue was (30)……… long that I wasn’t able to visit that part…»
so, correct. This is the so + adjective + that structure, expressing a result: «so long that I couldn’t…».
«…I wasn’t able to visit that part (31)……… the museum.»
of, correct. Part of is the fixed preposition that always goes with part when talking about a section of something.
«You can take (32)……… own picnic and eat in the museum garden…»
your, correct. The subject of the sentence is you, so the matching possessive is your.
Answers, in case you were keeping track: 27. every/each · 28. if · 29. to · 30. so · 31. of · 32. your.
Six numbered gaps (27 to 32), with no options to choose from.
Between six and eight minutes. The text is short, but working out the exact word with no hints takes a bit of thought.
Mostly function words: prepositions, conjunctions, articles, possessives, pronouns and auxiliary verbs. Rarely a content noun, verb or adjective.
Yes, it was introduced with the 2020 reform, just like Part 4, and it resembles B2 First’s Use of English Part 2.
Yes. Since you write the word yourself, a spelling mistake can mean the answer is marked wrong.
There’s no penalty in the B1 Preliminary, so fill in all six gaps even if you’re unsure.
If you’d rather practise with full exams and mark your own work, I have a book dedicated to exactly that: Reading B1: The Ultimate B1 Reading Guide & 10 B1 Reading Tests with Answers. It includes:
This is the sixth guide in a six-part series covering each part of B1 Preliminary Reading. You’ll find the rest at Reading Part 1, Reading Part 2, Reading Part 3, Reading Part 4 and Reading Part 5, or you can go back to the overall picture in my guide to B1 Preliminary Reading and the main B1 Preliminary page.
If these guides were useful, share them with whoever’s preparing for the PET alongside you, and if you’re left with any doubts about any part of the Reading paper, leave them in the comments — I answer every one.
Good luck in your exam. And remember, don’t forget to keep smiling! 🙂
