Why grammar comes first in PTE fill in the blanks
PTE has two reading fill-in-the-blanks tasks: a drop-down list for each gap (RW FIB) and one shared word box (Reading FIB). The method differs, and Reading FIB vs RW FIB covers that. What both share is options that are often close in meaning, so reading for meaning first is slow.
Grammar is faster. The words either side of a gap fix its word class (noun, verb, adjective, adverb) and its form (base verb, -ing, past participle, singular or plural). Check those first and most wrong options fall away in seconds.
Every gap that grammar settles in seconds is a mark banked, and time saved for the gaps that need meaning. The guides list no deduction for a wrong blank, so fill every gap. For where these tasks sit in your whole Reading score, see how to improve your PTE reading score.
PTE fill in the blanks grammar rules: the five signals
This is BandLadder advice: before you read the options, look at the word just before the gap and name what it demands. Five signals do most of the work.
Five signals before a gap
| Signal before the gap | What the gap needs | What it removes |
|---|---|---|
| a / an / the / this / their | A noun, or an adjective if a noun comes straight after the gap. After an, a word that starts with a vowel sound. | Verbs and adverbs; after an, words starting with a consonant sound |
| A preposition (of, by, for, without, after) | A noun, a pronoun or an -ing form | Base verbs, to-infinitives, past forms |
| An auxiliary (can, must, will / has, had / is, was, been) | Modal: base verb. Have: past participle. Be: -ing if the subject acts, past participle if something is done to it | Every other form of the same verb |
| The subject (plural or singular) | A verb that agrees: plural subject, no -s and were not was. Several, many, these: plural noun. Each, every, this: singular | The form that does not agree |
| to | Usually a base verb (to slow). After phrases like look forward to or committed to, a noun or -ing form | Other forms of the verb, or the base verb when 'to' is a preposition |
Look one word to the right as well: a noun after the gap means the gap is probably an adjective.
How to solve a gap in four moves
- 1
Read the word before. Article, preposition, auxiliary, 'to', or the end of a subject?
- 2
Read the word after. A noun straight after the gap usually means an adjective goes in.
- 3
Cross out. Remove every option of the wrong class or form before you think about meaning.
- 4
Then meaning. Choose between the survivors by sense and collocation.
PTE reading and writing fill in the blanks examples
An original RW FIB-style passage with the answers in place. Each gap's options differed mainly in form, not meaning, so only grammar could decide. The notes show which signal removed what.
Railway companies in snowy regions learned that ploughs alone could not keep lines open. Instead, they placed wooden fences some distance from the track to slow1 to the wind. Most fences were built2 aux from narrow slats with gaps between them, and the spacing of the slats was3 subject carefully measured. Because the slowed air dropped its snow behind the fence rather than on the rails, crews were spared hours of digging4 prep. Where the ground was too steep for fences, a row5 article of trees was sometimes planted instead.
- → 1. slow / slowing / slowed / slows: after to, only the base verb slow fits.
- → 2. build / building / built / builds: fences do not build anything, so after were the passive needs built.
- → 3. was / were / are / have: the subject is spacing, not slats, so was. The plural noun next to the gap is the trap.
- → 4. dig / digging / dug / to dig: after the preposition of, only digging fits.
- → 5. row / rows / rowed / rowing: after a, a singular noun: row.
Often, though, the four options are different words already in the right form. Then grammar has done its job and you move to meaning and collocation, which is where choosing between two answers that both fit picks up. Practise the signals on BandLadder's RW FIB questions.
PTE reading fill in the blanks grammar tips (drag and drop)
In drag and drop, the same five signals apply; the difference is that you label the gaps, not a list. BandLadder advice: before touching the box, write down what each gap's signal demands (base verb, -s verb, past participle, singular or plural noun), then look for that form. Using the shared box to eliminate across gaps is a separate skill, covered in Reading FIB vs RW FIB.
Marram grass is one of the few plants able to surviveto on bare coastal sand. Its roots spread sideways for several metresplural, binding loose grains together. When wind buries the plant, new shoots push up through the sand, so the dune around it growssubject higher each year. Volunteers are trainedaux to set each clump at the right depth. Without this protectiondeterminer, a storm can strip a young dune in a single night.
- → Box: survive, metres, grows, trained, protection, dunes, rapidly.
- → Labels first: after able to, a base verb; after several, a plural noun; after singular the dune, an -s verb; after are, with volunteers being taught, a past participle; after this, a singular noun.
- → Each label matches one form in the box: survive, grows, trained, protection. The adverb rapidly matches no label, so it is a spare.
- → The dune around it is the trap: 'around it' sits before the verb, but the subject is still singular dune.
- → The plural-noun label fits two words, metres and dunes. Grammar leaves two; meaning picks metres.
The labels settled four gaps alone and narrowed the fifth to two. Try it on BandLadder's Reading fill in the blanks questions.
PTE fill in the blanks grammar traps
Three signals hide a trap, and one spelling rule catches people out.
✗ The parish is committed to restore the old windmill.
✓ The parish is committed to restoring the old windmill.
Here 'to' is a preposition: you can say 'committed to it'. Prepositions take a noun or -ing, not a base verb.
✗ The cost of the new sluice gates were shared by two villages.
✓ The cost of the new sluice gates was shared by two villages.
Find the head noun of the subject (cost), not the nearest noun (gates).
✗ Each of the kilns have its own chimney.
✓ Each of the kilns has its own chimney.
Each is singular, even when a plural noun follows 'of'.
✗ Every snowflake forms an unique pattern.
✓ Every snowflake forms a unique pattern.
A or an depends on sound, not spelling: unique starts with a 'y' sound.
If one signal keeps catching you, usually verb forms after auxiliaries, work through that topic in Grammar Hub.
Your turn: PTE fill in the blanks grammar check
Use only the signal before the gap. Choose the one option that fits, then check the why.
- Restorers clean old tapestries by ______ them gently with a low-suction vacuum.
- A. treat
- B. treating
- C. treated
- D. treatment
Show answer
treating
After the preposition 'by' you need a noun or -ing; 'treatment' is a noun but cannot take the object 'them'.
- Several villages look forward to ______ the lavender harvest each July.
- A. celebrate
- B. celebrating
- C. celebrated
- D. celebrates
Show answer
celebrating
In 'look forward to', 'to' is a preposition, so it takes -ing, not the base verb.
- The weather balloons launched from the station each morning ______ data back within minutes.
- A. send
- B. sends
- C. sending
- D. to send
Show answer
send
The subject is 'balloons' (plural), so no -s; 'morning' is not the subject.
- Falconers describe the bird's return to the glove as an ______ moment.
- A. memorable
- B. special
- C. unforgettable
- D. striking
Show answer
unforgettable
All four make sense, but only 'unforgettable' starts with a vowel sound after 'an'.
- Each climbing rope must be ______ by an instructor before use.
- A. inspect
- B. inspecting
- C. inspected
- D. inspects
Show answer
inspected
Modal plus 'be' plus 'by an instructor' is passive, so the past participle.

Questions
FAQ
What are the grammar rules for PTE fill in the blanks?+
Five signals before the gap do most of the work: an article or determiner, a preposition, an auxiliary verb, the subject (for agreement) and 'to'. Each one fixes the word class or form the gap needs.
How do you solve PTE reading fill in the blanks using grammar?+
Label each gap with the form its signal demands, such as a base verb after 'to' or a plural noun after 'several', then find that form in the box. Use meaning only to choose between words with the same form.
Are there tricks for PTE fill in the blanks?+
There is no trick, but there is an order: grammar first, then meaning. Checking the word before and after each gap removes the options of the wrong class or form in seconds.
How can I improve fill in the blanks in PTE?+
Practise naming the signal before you read the options, and keep a note of which signal you miss most, often verb forms after auxiliaries. When two options share the right form, work on collocation.
