IELTS Reading: Summary Completion
Summary completion tests whether you can find the part of the passage that matches a shortened paraphrase of it, then choose or supply the exact word(s) that complete the gap accurately and grammatically.
What this question looks like
You are given a short paragraph or set of sentences that summarises part of the reading passage, with several words missing and replaced by numbered gaps. Sometimes you fill gaps using words taken directly from the passage (with a stated word limit, e.g. "NO MORE THAN TWO WORDS"); sometimes you choose answers from a box of options listed below the summary. The summary usually follows the same order as the information in the passage, though it summarises only one section, not the whole text. Each gap tests one specific fact, so precision matters more than general understanding.
Step-by-step approach
- 1Read the summary first, all the way through, to understand its overall topic and structure before looking at the passage. This tells you roughly which section of the passage it summarises.
- 2Identify the word class needed for each gap by looking at the grammar around it: is it a noun, verb, adjective, or number? This narrows your search and prevents you wasting time considering words that don't fit grammatically.
- 3Underline or note key words near each gap in the summary (dates, names, technical terms) and scan the passage for matching or paraphrased ideas, since the summary rarely uses the passage's exact wording except for proper nouns and numbers.
- 4Check the word limit instruction carefully (e.g. ONE WORD ONLY vs NO MORE THAN TWO WORDS) and never exceed it, since exceeding it makes an otherwise correct answer wrong.
- 5If answers come from a word bank, eliminate options as you use them and watch for distractors that fit grammatically but change the meaning of the original sentence.
- 6After filling every gap, re-read the completed summary sentence aloud in your head to confirm it makes logical and grammatical sense as a standalone sentence.
Worked example
Passage extract: 'Urban beekeeping has grown rapidly in the last decade, partly because city rooftops offer bees a wider variety of flowering plants than many rural monoculture farms, where a single crop dominates for miles. Beekeepers in cities also report lower pesticide exposure, since municipal parks tend to use fewer chemical treatments than large-scale agricultural land.' Summary: 'City bees often have access to a greater range of flowers than rural bees because farmland is frequently planted with only one type of _______.' What word from the passage completes the gap?
crop
The summary paraphrases 'rural monoculture farms, where a single crop dominates' as 'farmland is frequently planted with only one type of _______'. The gap needs a noun describing what is planted, and the passage supplies exactly that word: 'crop'. Grammatically it fits after 'one type of', and it is a single word, satisfying a typical 'ONE WORD ONLY' limit. 'Monoculture' would not fit the sentence structure as naturally and changes the part of speech expected.
Try it yourself
Read the short passage and summary sentence, then choose the option that correctly completes the gap.
Passage: 'Many coastal towns are turning to floating solar panels as land becomes scarce for large installations. These panels sit on reservoirs and slow the evaporation of water beneath them, an added benefit in regions facing drought. However, engineers note that panels must be specially treated to resist corrosion from constant exposure to moisture.' Summary: 'Floating solar panels are useful in areas without much available land, and they also help to reduce water _______ from reservoirs.' Choose the correct word to complete the summary.
Common mistakes
- !Choosing a word that fits the meaning but breaks the word limit, such as writing two words when only one is allowed.
- !Copying a word straight from the passage without checking it fits grammatically into the summary sentence (wrong tense, wrong singular/plural form, wrong part of speech).
- !Assuming the summary follows the passage word-for-word, then failing to recognise a paraphrase and missing the correct section entirely.
- !Picking a word bank option because it appeared near the right area of the passage, without checking it matches the specific meaning required by the gap.
- !Not re-reading the finished sentence to check overall logic, which can leave answers that are grammatically fine but factually contradict the passage.
Quick quiz
1. Before scanning the passage in detail, what is the most useful first step for summary completion?
2. A gap in the summary reads 'the study found a significant _______ in reported cases.' What should you determine first?
3. Why is it risky to choose a word bank option simply because it appeared in the correct paragraph of the passage?
4. If the instructions say 'NO MORE THAN TWO WORDS', and the correct concept in the passage is expressed as 'renewable energy sources', what should you write?

Do the answers in summary completion always come in the same order as the passage?
Usually yes, since the summary follows the sequence of ideas in the section of the passage it is based on. However, the summary typically only covers one part of the passage, not the whole text, so don't assume gap 1 is near the very start of the reading.
Can I use a word that's a synonym of the passage's word instead of the exact word?
Generally no, unless the question specifically allows it; most summary completion tasks require you to use the exact word or words from the passage, since spelling and grammatical form are checked precisely. If you paraphrase instead of copying, your answer is usually marked incorrect even if the meaning is right.
What's the difference between summary completion with a word bank and without one?
Without a word bank, you find and copy the answer directly from the passage while respecting a stated word limit. With a word bank, you choose from a fixed list of words or phrases below the summary, which removes spelling risk but adds the challenge of avoiding grammatically-tempting distractors.
