📝 Summarizing and Paraphrasing
🎯 Learning Objectives
After studying this topic, you will be able to:
- Summarize a long text into a concise version (⅓ of original length)
- Paraphrase a sentence or passage in your own words without changing meaning
- Distinguish between summarizing, paraphrasing, and quoting
- Avoid plagiarism by properly citing sources
- Apply techniques like synonym replacement, sentence restructuring, and voice change
📋 Prerequisites
- BSHS1001 Week 2: Vocabulary Building — using synonyms effectively
- BSHS1001 Week 5: Sentence Structure — transforming sentence types
- BSHS1001 Week 6: Paragraph Writing — understanding paragraph structure
3. 📖 Core Content
3.1 Intuition: Why Summarize and Paraphrase?
Imagine your friend tells you a 10-minute story about their vacation. When you retell it to another friend, you do NOT repeat every word. You summarize: "She went to Goa, had a great time at the beaches, and ate amazing food." That is summarizing — shortening without losing key information.
Now imagine reading a definition in a textbook. You understand it, but you want to write it in your own words for your notes. You paraphrase: you keep the same meaning but change the words and sentence structure.
Real-world context: In academic writing, you MUST use your own words. Copying directly from sources = plagiarism (a serious offense). Summarizing and paraphrasing show that you understand the material AND help you avoid plagiarism.
3.2 Summary vs. Paraphrase vs. Quotation
| Technique | Length | Words | Purpose |
|---|---|---|---|
| Summary | Much shorter (⅓ or less) | Your own words | Give the main points of a long text |
| Paraphrase | Similar length | Your own words | Explain a passage in different words |
| Quotation | Exact same | Author's words | Use the original for impact or authority |
Example
Original (50 words):
"Climate change, driven primarily by human activities such as the burning of fossil fuels and deforestation, has led to a measurable increase in global average temperatures. This warming has resulted in melting polar ice caps, rising sea levels, and more frequent extreme weather events across the planet."
| Technique | Result | Length |
|---|---|---|
| Summary | "Human-caused climate change is raising global temperatures, melting ice caps, and causing more extreme weather." | 16 words (⅓) |
| Paraphrase | "Global temperatures are rising mainly because humans burn fossil fuels and cut down forests. Consequently, ice caps are melting, sea levels are rising, and extreme weather is becoming more common." | 34 words (similar length) |
| Quotation | "Climate change, driven primarily by human activities such as the burning of fossil fuels and deforestation, has led to a measurable increase in global average temperatures." | Exact copy in quotation marks |
3.3 How to Summarize
The 5-Step Summary Process
(Diagram)
Step-by-Step Example
Original Passage (120 words):
"The Industrial Revolution, which began in Britain in the late 18th century, marked a major turning point in human history. It transformed agrarian and craft-based economies into industrial powerhouses. Key inventions like the steam engine, spinning jenny, and power loom revolutionized manufacturing and transportation. This led to rapid urbanization as people moved from rural areas to cities for factory work. However, the Industrial Revolution also brought significant challenges, including poor working conditions, child labor, and environmental pollution. Despite these problems, the era laid the foundation for modern technological advancement and economic growth." Step 1 — Read and understand: The passage is about the Industrial Revolution — its positive transformations AND negative consequences. Step 2 — Identify main idea: The Industrial Revolution transformed economies and society through new inventions, causing urbanization but also problems like poor working conditions. Step 3 — Note key points:
- Began in Britain in late 1700s
- Transformed economies from agrarian to industrial
- Key inventions: steam engine, spinning jenny, power loom
- Led to urbanization
- Negative: poor conditions, child labor, pollution
- Positive: foundation for modern tech Step 4 — Write in your own words (summary):
"The Industrial Revolution began in late 18th-century Britain, transforming agricultural economies through inventions like the steam engine. It caused mass urbanization but also poor working conditions and pollution. Despite these issues, it enabled modern technological progress." Step 5 — Check length: Original: 120 words. Summary: 35 words (about ⅓). ✓
3.4 How to Paraphrase
6 Techniques for Paraphrasing
| Technique | Original | Paraphrase |
|---|---|---|
| 1. Synonym Replacement | "The results were significant." | "The findings were important." |
| 2. Change Word Order | "Although it was raining, we went out." | "We went out despite the rain." |
| 3. Change Voice (Active ↔ Passive) | "The team conducted the experiment." | "The experiment was conducted by the team." |
| 4. Change Part of Speech | "She analyzed the data carefully." | "She conducted a careful analysis of the data." |
| 5. Combine/ Split Sentences | "The sun set. The stars appeared." | "After the sun set, the stars appeared." |
| 6. Change Clause Structure | "The man who lives next door is a doctor." | "The man living next door is a doctor." |
Worked Example: Full Paraphrase
Original:
"Renowned physicist Stephen Hawking made groundbreaking contributions to our understanding of black holes and the origins of the universe, despite being diagnosed with a debilitating motor neuron disease at the age of 21." Paraphrase (using multiple techniques): "Stephen Hawking, a famous physicist, transformed how we understand black holes and the universe's beginnings. He achieved all this even though he was diagnosed with a serious motor neuron disease when he was only 21 years old."
| Technique Used | Original | Paraphrase |
|---|---|---|
| Synonym | "Renowned" | "famous" |
| Restructure | "made groundbreaking contributions to our understanding of" | "transformed how we understand" |
| Split sentence | One long sentence | Two sentences |
| Reorder | "despite being diagnosed... at the age of 21" | "He achieved all this even though..." |
3.5 Summarizing vs. Paraphrasing: Which to Use?
| Situation | Use |
|---|---|
| You need to explain a whole chapter or article | Summary |
| You want to use a specific point from a source | Paraphrase |
| The original wording is particularly powerful | Quotation |
| You are writing a literature review | Summary (of each paper) |
| You are explaining a technical concept in simpler words | Paraphrase |
3.6 Avoiding Plagiarism
Plagiarism = using someone else's words or ideas without giving credit.
What Counts as Plagiarism?
| ❌ Plagiarism | ✅ Acceptable |
|---|---|
| Copying a sentence without quotation marks | Using quotation marks + citation |
| Changing 2-3 words but keeping the structure (patchwork paraphrase) | Full paraphrase + citation |
| Using someone's idea without credit | Citing the source |
| Using AI-generated text as your own | Using AI as a tool but writing in your own voice |
The "Patchwork" Problem
Original: "Regular exercise strengthens the heart and improves circulation."
❌ Plagiarism (patchwork): "Regular physical activity strengthens the heart and improves blood flow." (same structure, only a few synonyms changed)
✅ Acceptable (true paraphrase): "One of the key benefits of physical activity is that it enhances cardiovascular health by fortifying the heart muscle and promoting better blood circulation."
3.7 Annotated Example: Bad vs. Good Paraphrase
Original Text:
"The rapid expansion of urban areas in developing countries has created unprecedented challenges for infrastructure systems, including transportation networks, water supply, and waste management." Bad Paraphrase (Plagiarism): "The quick expansion of urban regions in developing nations has created unmatched challenges for infrastructure systems, such as transportation networks, water supply, and waste management."
| What's Wrong | Annotation |
|---|---|
| "quick expansion" | Just synonym for "rapid expansion" |
| "urban regions" | Synonym for "urban areas" |
| "developing nations" | Synonym for "developing countries" |
| "unmatched challenges" | Synonym for "unprecedented challenges" |
| Same structure! | Still follows the exact same sentence pattern |
Good Paraphrase:
"Cities in developing countries are growing quickly, which puts enormous pressure on their infrastructure. Roads, water systems, and waste disposal facilities struggle to keep up with the increasing population."
| What's Right | Annotation |
|---|---|
| "Cities in developing countries are growing quickly" | Different starting point |
| "enormous pressure" | Different way of expressing "challenges" |
| "Roads, water systems, and waste disposal facilities struggle to keep up" | Different sentence structure and word choice |
3.8 Précis Writing (Advanced Summary)
Précis (pronounced /preɪsi/) is an even more concise summary — typically ⅓ of the original.
Rules of Précis Writing
| Rule | Explanation |
|---|---|
| 1. Reduce to ⅓ | The précis must be about one-third of the original word count |
| 2. Use your own words | Do not copy phrases from the original |
| 3. Maintain the tone | Keep the same mood (serious, formal, etc.) |
| 4. Keep the order | Maintain the sequence of ideas |
| 5. No opinions | Do not add your own comments or judgments |
| 6. Use third person | Write in third person (he/she/it/they) |
| 7. Connect sentences | Use proper transition words |
Précis Example
Original (120 words):
"Thomas Jefferson is best known for the Declaration of Independence, in which he announced the separation of the 13 British colonies in North America — the right of Americans in these places to govern themselves. The declaration listed grievances against King George III and articulated the philosophical foundations of democratic governance, including the idea that all men are created equal and endowed with unalienable rights. This document became a cornerstone of American democracy and influenced liberation movements worldwide." Précis Development:
| Draft | Words | Notes |
|---|---|---|
| 1st draft: "Thomas Jefferson announced the separation of the 13 British colonies of North America and their right to govern themselves." | 19 | Too long |
| 2nd draft: "Thomas Jefferson declared the 13 British colonies of North America were independent and would henceforth govern themselves." | 17 | Better |
| Final draft: "The 13 British American colonies would henceforth govern themselves, declared Thomas Jefferson." | 12 | ✓ (⅓ of original) |
3.9 Key Concepts Summary Table
| Concept | Definition | Length | When to Use |
|---|---|---|---|
| Summary | Short version of a longer text in your own words | ⅓ or less | Book/article overview |
| Paraphrase | Restatement of a passage in your own words | Similar | Explaining a specific point |
| Quotation | Exact words from the source in "..." | Exact | Powerful original wording |
| Précis | Extremely concise summary | ⅓ | Academic précis exercises |
| Plagiarism | Using others' words/ideas without credit | N/A | NEVER acceptable |
| Patchwork | Superficial paraphrase (changed words, same structure) | Similar | Also plagiarism |
4. Common Pitfalls
Pitfall 1: Patchwork Paraphrasing
- Mistake: Changing 2-3 words but keeping the exact same sentence structure
- Why: Students think "different words = different text"
- How to fix: Read the original, close it, then write what you remember. If your version looks like the original, rewrite it.
- Correct: Change both words AND structure.
Pitfall 2: Adding Opinions in a Summary
- Mistake: "The author argues that pollution is harmful. I think this is a valid point."
- Why: Students confuse summary with response
- Rule: A summary is NEUTRAL. It reports what the original says WITHOUT your opinion.
- Correct: "The author argues that pollution is harmful." (stop there)
Pitfall 3: Making the Summary Too Detailed
- Mistake: Including minor examples and statistics in a summary
- Why: Students cannot distinguish main ideas from supporting details
- How to fix: Ask: "If I could only keep 3 sentences, which would they be?"
- Correct: Include only the main idea and key supporting points; leave out examples and data.
5. Practice Questions
Question 1
Which is the BEST summary of this passage?
"The internet has revolutionized communication, commerce, and education.
